ACGI Dispatcher

Current Version: 3.0fc1 (November 10, 2008)

On Mac OS versions 9 and earlier, once could write applications that ran as "ACGI programs" in AppleScript or other languages that could handle Apple Events. Under OS X, Apache doesn't know how to send Apple Events, so you're out of luck. Apple includes an "ACGI Enabler" program with OS X Server, but chose not to include that with the standard edition. ACGI Dispatcher allows you to use traditional AppleScripts - or other programs that ran as ACGI programs under OS 9 - on OS X with Apache.

Version 3.0 adds/changes the following:

• Leopard compatibility
• Universal binary
• Ability to talk to bundled applications

AmphetaDesk

Open source; $0

Current Version: 0.93.1 (October 31, 2002)

AmphetaDesk is a remarkable program. In short, AmphetaDesk is a news aggregator - it sits on your desktop, downloads the latest news that interests you, and displays them in a quick and easy to use (and customizable) web page. AmphetaDesk actually functions as a simple web server (written in Perl but not requiring a separate download of the MacPerl package) that contacts and collects news from selected XML-based (RSS) news sites to be combined and served in a simple web page format that is served to your web browser (or to other people's browsers, should you care to broadcast the address of your server) by your very own computer.

All this is not as complicated as it sounds; using it is a download-and-double-click affair, and customization and selection of content is done through your web browser. Because it's written in Perl, however, AmphetaDesk runs more slowly than you might like, and it may have a speed impact on other running applications. That said, it's an awful lot of fun, and since it's absolutely free and the source code is available, it's worth a look by any geek who can't get enough news - yours truly included.

Version 0.93.1 makes a whole slew of changes, all of which are fully detailed on the AmphetaDesk CHANGELOG page.

BlueDragon

Commercial; See text

Current Version: 7.0.1.352 (November 30, 2007)

New Atlanta Communications, LLC produces BlueDragon, a low-cost ColdFusion Markup Language (CFML) application server that is widely used and admired. BlueDragon is available for Mac OS X in two editions: Server and Server JX.

The BlueDragon Server family of Java-based servers (Server and Server JX) enables the stand-alone deployment of CFML. Both BlueDragon Server versions contain a built-in web server for development and testing, and each integrates with Microsoft IIS, Sun ONE/Netscape/iPlanet (JX only), and Apache web servers for deployment.

Those looking to replace CFML with ASP or PHP due to budgetary reasons might consider sticking with CFML instead, deploying the base version of BlueDragon Server on Windows, Mac OS X or Linux platforms for free. BlueDragon Server includes support for CFCs, XML, Web Services, and Java and C++ CFX tags.

BlueDragon Server JX adds additional functionality to BlueDragon Server, including precompiled/encrypted CFML templates, J2EE session management, enterprise database drivers, support for SSL, support for additional OS/web server combinations - plus the ability to deploy hybrid CFML/JSP web applications (including shared access to data within J2EE sessions, ability to perform includes between CFML and JSP pages, calling Java objects from CFML, and more).

BlueDragon Server is free and BlueDragon Server JX is $899. See the BlueDragon Feature Comparison matrix for more information on the differences between BlueDragon Server and BlueDragon Server JX.

Version 7.0.1.352 adds/changes the following:

• Fixed #2691: Internal Server Error when connection attribute is excluded from a cfftp tag
• Fixed #2962: comparing strings containing only days of the week always returns true
• BlueDragon 7.0.1 final release

DansGuardian

See text.

Current Version: 2.10.1.1 (June 8, 2009)

DansGuardian is an award winning web content filtering proxy for Linux, FreeBSD, OpenBSD, NetBSD, Mac OS X, HP-UX, and Solaris that uses Squid to do all the fetching. It filters using multiple methods. These methods include URL and domain filtering, content phrase filtering, PICS filtering, MIME filtering, file extension filtering, POST limiting. The content phrase filtering will check for pages that contain profanities and phrases often associated with pornography and other undesirable content. The POST filtering allows you to block or limit web upload. The URL and domain filtering is able to handle huge lists and is significantly faster than squidGuard. The filtering has configurable domain, user and source ip exception lists. SSL Tunneling is supported. The configurable logging produces a log in an easy to read format which has the option to only log the text-based pages, thus significantly reducing redundant information such as every image on a page. Pretty much all parts of DansGuardian are configurable thus giving the end administrator user total control over what is filtered and not some third-party company.

DansGuardian 2 is:

• free for non-commercial use
• not free for installation by 3rd parties charging for installation or support
• not free for commercial use
• licensed under the GPL

Version 2.10 is the first new "stable" release since August 2005, and includes a host of changes from the 2.8 series. Here are the highlights:

• Built-in content scanner plugin system which includes AV scanning
• NTLM and persistent connection support
• Header analysis and manipulation so you can manipulate cookies
• Large file (2GB+) download & scanning support
• Autotools build system
• URL regular expression replacement so you can force safe search in Google
• Deep URL scanning to spot URLs in URLs to for example block images in Google images
• Advanced advert blocking
• Many performance improvements
• Updates to handle all current web technology trends
• Blanket SSL blocking so you can block SSL anonymous proxies and allow access to legitimate SSL sites such as banking by whitelisting

Version 2.10.1.1 is a bugfix release that makes the following additional changes:

• Add "originalip" option to dansguardian.conf, for determining the original destination IP in transparent proxy set-ups, and ensuring that the destination domain of the request resolves to that IP. This can help to address a particular transparent proxy security vulnerability (US-CERT VU#435052), but because of certain limitations - only implemented on Linux/Netfilter; potential breakage of websites using round-robin DNS - the code is not enabled by default. Enable by passing "--enable-orig-ip" to the configure script.
• Fix a crash which could occur when dealing with simultaneous incoming connections in configurations using more than one listening socket.
• Fix a crash when checking time limits on item lists.
• Fix potential usage of uninitialised memory during phrase filtering.

DNS Enabler

Shareware; $15

Current Version: 2.1.1 (July 10, 2007) / 3.0.4 (August 4, 2008) / 4.0.5 (March 12, 2010)

DNS Enabler is an inexpensive shareware application that takes the work out of configuring BIND, the DNS server built into Mac OS X. According to the authors, DNS Enabler "tries to be as buzzword-compliant as possible - it handles multiple virtual domains, multiple subnets, aliases, MX records (including specifying back-up servers on other networks), and creating the right number of reverse pointer and CNAME records - while doing it all using a single window, the Mac way."

Version 2.1.1 - the latest release for Mac OS X 10.3 & 10.4 - adds/changes the following:

• Fixed a bug which occurred when there is a domain, e.g. called ABC.com, and another, say, xyzABC.com which contains the same letters as the first domain. DNS Enabler got confused when it had to process both these domains in the same list. This has been sorted out and DNS Enabler is smarter now about these things.

Version 3.0.4 - the latest release for Mac OS X 10.5 (Leopard) - adds/changes the following:

• Fixed the config file to work with Apple's latest BIND 9.4.2-P1 update. Eliminates the "using specific query-source port suppresses port randomization and can be insecure" warning.

Version 4.0.5 - the latest release for Mac OS X 10.6 (Snow Leopard) - adds/changes the following:

• One cosmetic change - the question-mark icon for the new Dynamic DNS Update feature does not "stick" to its position when the window is re-sized. This has been fixed.
• Also the Authorisation Key generated for DNS Agent now also contains the name of the DNS Server to allow DNS Agent to be pre-filled with the name of its home DNS Server when its Authorisation Key is installed.

DNS Helper

Freeware

Current Version: 1.6 (November 7, 2003)

DNS Helper is a free application that takes the work out of configuring BIND, the DNS server built into Mac OS X. DNS Helper allows you to:

• Create zone, domain, db.cache, and named.conf files for your BIND server without the need to understand the formatting of those files.
• Set the needed permissions and ownership on the files after they are created.
• Install the files for you into the active system.
• Have total control over the DNS Server with the ability to start, stop, and reload BIND.
• Set the DNS Server to start at boot time.
• Read and save the system.log, filtering out the non-DNS Server related entries if desired.

Currently, DNS Helper does not do the following:

• Edit or maintain existing files.

With the 1.5 release, DNS Helper became a full replacement for Mac OS X Server's Server Settings DNS module. Actually, it can do quite a bit more than the Apple software can as of Spring, 2003.

Elektron

Commercial; $750

Current Version: 2.1.2376 (October 4, 2009)

Periodik Labs (formerly Corriente Networks LLC) produces Elektron, which is a software-based server that provides RADIUS/802.1X authentication services for Wi-Fi networks.

While version 2.1 is a bugfix release, version 2.0 added/changed the following:

• Authentication Domains - Authentication domains allow you to map users to different authentication sources based on the user's domain. For instance, "user@foo.com" can be authenticated against your Active Directory, while "user@bar.com" can be authenticated against a remote LDAP server. Even if you have only a single domain, this feature gives you the ability to add support for guest accounts: configure "company.com" to authenticate against your company's user directory, while "guest.company.com" is configured to use Elektron's built-in user database for easy temporary account creation.
• FIPS 140-2 Validated Cryptographic Module - Elektron version 2 uses a cryptographic module that has been tested and validated under the NIST Cryptographic Module Validation Program as meeting requirements for FIPS PUB 140-2, enabling its use in certain government and financial industry applications.
• MAC Address Authentication Simultaneous use of MAC address and standard user account authentication is supported in Elektron version 2, and is fully configurable on a per-access point basis.
• Full Windows Vista Support - Elektron's Windows Vista feature set has been updated to include full support for installation on Vista (including UAC support) and to authenticate Windows Vista clients when installed on any supported platform.
• SNMP - Elektron can be configured to to respond to SNMP management information requests in accordance with the standardized RADIUS MIBs, and to issue SNMP traps is response to a user-configurable set of server events.
• Authorization Policies - Policy support has been enhanced in Elektron version 2, with new support for triggering actions based on string pattern matching of the username, account groups, access points, and MAC addresses. Support for external scripts includes the ability to trigger policies based on the script result, and to have an external script act upon the result of the policy. Also included is greatly simplified configuration of VLAN assignment, one of the most common uses of authorization policies.
• EAP-FAST - Support for Cisco's EAP Flexible Authentication via Secure Tunneling protocol makes its debut in Elektron version 2.
• Least Privilege - Elektron version 2 honors the "principle of least privilege," in which the server performs its normal functions at the lowest possible level of security privilege, closing potential avenues of attacks on your server.

• [MODIF] Display the name of the server instead of its IP

Muffin

Current Version: 0.9.3a (April 4, 2000)

Muffin is an interesting beast. It's one of the few Java applications that I list on the Orchard (if I were to include every Java application that had useful Internet capability, I would never have time to maintain this site), and while its functionality is useful for users of all levels, installing and getting it up and running - while not difficult for experienced Mac users - is not for the faint of heart.

Basically, though, I include it here because it provides incredibly useful functionality that is not really provided by any other free Macintosh software.

Briefly, Muffin is a World Wide Web "filtering system" that acts as a proxy server to filter out content to your own specifications. It can be used to filter any or all of the following:

• animations
• cookies
• Java applets
• JavaScripts
• referer response information

 . . . and a whole lot more. Its core features include:

• Written entirely in Java. Requires JDK 1.1
• Runs on Unix, Windows 95/NT, and Macintosh.
• Freely available under the GNU General Public License.
• Support for HTTP/0.9, HTTP/1.0, HTTP/1.1, and SSL (https).
• Graphical user interface and command-line interface.
• Remote admin interface using HTML forms.
• Includes several filters which can remove cookies, kill GIF animations, remove advertisements, add/remove/modify arbitrary HTML tags (like blink), remove Java applets and JavaScript, user-agent spoofing, rewrite URLs, and much more.
• View all HTTP headers to aid in CGI development and debugging.
• Users can write their own filters in Java using the provided filter interfaces.

Figuring out how to run Muffin on Classic Mac OS from the instructions on its Web site is needlessly intimidating. To save you the trouble, I've written a simplified set of instructions here:

To use Muffin, you'll need the following downloads (all free):

1. Mac OS Runtime for Java (otherwise known as "MRJ" and available on the Orchard's Helper apps page).
2. Apple's MRJ Software Development Kit.
3. The muffin.jar Java archive (control-click and save to disk if you have trouble with this link).

Once you have the two Apple MRJ products installed, you'll need to:

1. Place the muffin.jar file into the place where you want it to reside permanently.
2. Drag muffin.jar onto the JBindery application (located in the MRJ SDK folder under Tools | Application Builders | JBindery).
3. Enter "org.doit.muffin.Main" in the Class name: field, then click on the Classpath icon to make sure that the muffin.jar file is in the class path.
4. Finally, using the File menu select Save As... to give it a name and save it as an application. That's it!

By the way: you'll never have to do this again; now, you'll be able to double-click on the applet whenever you want to use Muffin (but you'll have to be online for it to run).

In order to use Muffin, you'll have to configure your Web browser's proxy settings (dig around your browser's preferences to find this) to point to Muffin so that it can intervene between you and the Web (which is exactly what a proxy server does). This is accomplished by setting your proxy server address to 127.0.0.1 (the magic "loopback" IP address that points to your own machine) and using port 51966.

Sit back, configure Muffin from its "Edit" menu, and you'll be ready to roll! It uses about 6-7 MB of RAM when running, and has excellent performance under MRJ 2.2.

For more information on Muffin, including documentation, visit the Muffin Web site.

NFS Manager

Shareware; €17.85

Current Version: 3.31 (March 17, 2010)

From the NFS Manager home page: "NFS Manager is a graphical user interface to control all built-in NFS features of Mac OS X. It can manage a whole network of Mac OS X computers to setup a distributed NFS file system via a few simple mouse clicks. The application is designed to use the latest technologies available in Mac OS X, like Open Directory, Bonjour, or Kerberos. If your network is setup as a Kerberos realm, secure NFS with authenticated and encrypted connections can be configured."

NFS Manager 3 is for Mac OS X Leopard or later only. Previous generations of Mac OS X use a very different implementation of NFS and therefore need a different management tool. Use NFS Manager 2 for legacy systems (Mac OS X 10.2.5 to 10.4.11).

Version 3.0 was redeveloped completely for Mac OS X 10.5 because Leopard uses a different NFS implementation. All aspects of the application have changed.

Version 3.31 makes the following additional changes:

• This version enhances compatibility with upcoming versions of Mac OS X Snow Leopard.

Paros

Open source; $0

Current Version: 3.2.13 (August 8, 2006)

Version 3.2.13 adds/changes the following:

• New: skipping designated URL in spider. Use options to set the spider.
• New: auto update menu and periodic check for update (Windows and Linux platform only).
• Fix: the use of new external library caused slower performance of proxy. Restored to older library.

See the installation instructions for more information.

Phantom

Commercial; see site.

Current Version: 2.2.5 (January 15, 2003) / 2.5 (August 24, 2003)

Aktiv Software Corporation produces the the Phantom web crawler/search robot formerly distributed by Maxum. Running on your web server, Phantom makes it possible for users to search your web site or other web sites. Phantom works like AltaVista (but on a smaller scale) so it can provide searching for remote web sites you specify using its built-in web crawler. Phantom supports indexing thousands of documents in a variety of formats including text, HTML and PDF. With its HTML form interface and web-based administration, Phantom makes it simple to implement basic searching but is also completely customizable for the more advanced Webmaster.

Post.Office

Commercial; $295

Current Version: 3.8.4 Rev. 115 (July 24, 2008)

For Mac OS X, Tenon has developed a direct port of the popular Post.Office mail server / list server, bundled with the SpamAssassin plugin. Post.Office is a SMTP/POP3/IMAP messaging server designed to meet the needs of small and mid-sized ISPs.

• Mac OS X Leopard compatible
• Unified Licensing

Privoxy

Open source; $0

Current Version: 3.0.16 (February 22, 2010)

From the Privoxy web site: "Privoxy is a web proxy with advanced filtering capabilities for protecting privacy, modifying web page content, managing cookies, controlling access, and removing ads, banners, pop-ups and other obnoxious Internet junk. Privoxy has a very flexible configuration and can be customized to suit individual needs and tastes. Privoxy has application for both stand-alone systems and multi-user networks." Privoxy is freeware, released under the GNU General Public License.

Version 3.0.16 (the latest source release) adds/changes the following:

• Added the config file option handle-as-empty-doc-returns-ok to work around Firefox bug #492459, which causes Firefox to hang if JavaScripts are blocked in certain situations. The option is enabled in the default config file.
• Added the config file option default-server-timeout to control the assumed default server timeout. Since Privoxy no longer returns an error message for connection resets on reused client connections, assuming larger server timeout values appears to actually work pretty well as long as connections aren't shared.
• Added optional support for FreeBSD's accf_http(9). Use the configure option --enable-accept-filter to enable it.
• Added fancier Privoxy icons for win32. Contributed by Jeff H.
• In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
• Resolve localhost using whatever address family the operating system feels like. Previous betas would try to use IPv4 as this is what most users expect, but this didn't work reliably on GNU/Linux systems.
• In the action lists on CGI pages, actions and their parameters are no longer separated with a space. The action file parser doesn't actually allow this and will throw an invalid syntax error if actions and parameters in the action files are separated. Not adding the spaces means copy and pasting CGI output into the action files works.
• The default keep-alive timeout has been reduced to 5 seconds to work around hangs in clients that treat the proxy like any other host and stop allowing any new connections if the "maximum number of connections per host" is reached.
• Several webbug URLs that look like they are leading to images are now blocked as image instead of empty documents. Doing the latter causes WebKit-based clients to show a "missing image" icon which may mess up the layout.
• The no-such-domain template is used for DNS resolution problems with FEATURE_IPV6_SUPPORT enabled. Previously the connect-failed template was used. Reported by 'zebul666'.
• Accepts quoted expiration dates even though RFC 2109 10.1.2 doesn't seem to allow them. Reported anonymously.
• Don't try to forget connections if connection sharing is disabled. This wasn't a real problem but caused an unnecessary log message.
• The still undocumented --enable-extended-host-patterns configure option has a better description.
• Fixed an error message that would claim a write to the server failed when actually writing to the client failed.
• Log the crunch reason before trying to write to the client. The log is easier to read that way.
• Several log messages about client connections also mention the socket number.
• handle-as-empty-document no longer depends on the image blocking code being enabled.
• Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
• uagen, a Firefox User-Agent generator for Privoxy and Mozilla browsers has been imported and is available in the tarball's tools directory.
• The scripts in the tools directory treat unknown parameters as fatal errors.

Radiator

Commercial; see text.

Current Version: 4.6 (February 5, 2010)

Open System Consultants Pty Ltd produces Radiator, one of two RADIUS implementations for the Mac that I'm aware of. Radiator is written in Perl and runs an just about any OS, including Mac OS 9 and Mac OS X.

Version 4.6 makes the following changes:

• Improved AuthLog SYSLOG to support multiple SYSLOG clauses with different LogHost and LogSock options. No comnpatible with multiple Log SYSLOG clauses. Reported by "Martin van der Walle".
• Improvements to example init script for Linux in linux-radiator.init, to be compliant with LSB requirements in http://wiki.debian.org/LSBInitScripts
• AuthBy LDAP2 now detects LDAP_INVALID_DN_SYNTAX errors and interprets them as a per-request error and not a connection failure. When LDAP_INVALID_DN_SYNTAX error occurs, the LDAP connection wil not be shut down. Requested by Dawn Lovell.
• Fixed a problem in Server TACACSPLUS where an AuthorizeGroup of the formAuthorizeGroup group1 permit service=shell cmd\* {autocmd="telnet 169.163.226.81"} would result in the autocmd being sent incorrectly with 2 equals signs.
• AuthBy SQLYUBIKEY now supports static passwords in any format supported by Radiator, including plaintext, {SHA}, {crypt}, {MD5}, {rcrypt}, {mysql}, {mssql}, {nthash}, {dechpwd}, {NS-MTA-MD5}, {clear} etc. TranslatePasswordHook is also supported. Suggested by Jerome Fleury.
• Minor updates to Yubikey documentation to reflect the fact that AES keys must be programmed into each Yubikey before being imported into the SQLYUBIKEY database. Changes to AuthBy SQLYUBIKEY default SQL queries to work better with databases where the tokenID and AES key are in Hex. Yubikey keys may now be present in the database in either hex (no spaces) or base64 format. But the default queries assume the Token ID and AES secret are in Hex, and that there is a one-to-one mapping between users and Yubikeys. Other options are available with custom SQL queries.
• Fixed a problem in AuthBy SQLYUBIKEY where it would sometimes incorrectly detect a replay attack in during multiple authentication of the same Yubikey session. General improvements to the AuthBy SQLYUBIKEY replay detection. Replay detection now uses the session counter and the session_use counter. The timestamp is not used. The database column that previously held the timestamp_low is used for the session_use counter. The database column that previously held the timestamp_high is not used.
• Updated install.html installation instructions for Windows.
• Improvements to AuthBy EAPBALANCE and AuthBy HASHBALANCE to work better in multi-AP roaming TTLS/PEAP session resumption environments. The default behaviour of AuthBy HASHBALANCE is to compute the HASH based on the same attributes as the EAP context. This prevents false detection of loss of continuity in EAP streams. AuthBy EAPBALANCE now sets the State in all replies in an EAP stream, not just the first, in order to work correctly with some non-compliant APs. AuthBy HASHBALANCE is deprecated in favour of AuthBy EAPBALANCE in any EAP-capable environment.
• In Server DIAMETER, fixed a problem that prevented some RADIUS reply attributes being correctly translated into Diameter reply attributes.
• Added new module AuthBy SQLMOTP for MOTP authentication, a new strong, two-factor authentication with mobile phones. See http://motp.sourceforge.net for details.
• In diapwtst, fixed a problem that would result in an incorrect status report: "Unexpected result code: DIAMETER_SUCCESS".
• Improvements to the internal structure of ServerDIAMETER.pm, making it easier to override handling of specific Diameter request types.
• Fixed a problem with AuthBy VOLUMEBALANCE, where if multiple failed hosts are configured with FailureBackoffTime of 0, it was possible for a request to be handed to each host in turn forever.
• Added new sample configuration file goodies/crypto-mas.cfg, showing how to proxy requests to the Cryptocard MAS (Managed Authentication Service) CRYPTO-MAS. See http://www.cryptocard.com/
• Added new parameter MaxTargetHosts to AuthBy VOLUMEBALANCE. Limits the number of different hosts a request will be proxied to in the case of no reply. Defaults to 0 which mean no limit: if the load balancer does not receive a reply from a host, it will keep trying until all hosts are exhausted.
• Improvements tp RPM spec file to permit installation with Perls that do not include /usr/lib/perl5/site_perl/, such as SLES. Reported by Frank Messie.
• Improvements to the rpm: make target so the RPM build correctly uses the local perl version number for links in the Perl lib. Contributed by Bjoern.
• Updated expired test certificates.
• Fixed a problem with incorrect type in replies to proxied Change-Filter-Request. Reported by Belmont Cheung.
• Added support for UpdateQuery in SessionDatabase SQL. Patch supplied by Jose Borges Ferreira.
• Added support for RFC 4818 compliant packing and unpacking of Delegated-IPv6-Prefix. Added new dictionary type ipv6prefix.
• The TacacsPlus group cache GroupCacheFile now uses the IP address of the client as part of the key, so that in situations where the group name depends on the client the correct group name wil be retrieved.
• Some Expiration check items in the sample users file had actually expired, causing the test suite to incorrectly fail on tests 2l, 2m, 3g and 3h.
• Fixed a problem that could cause incorrect authentication of HOTP passwords with leading zeroes.
• Added support for TOTP (Time-based one-time-passwords) as specified in draft-mraihi-totp-timebased-04.txt. Sample configuration and database schema included.

The software is available for online purchase for $840 - $7,140.

RumorMill (formerly made by Stairwars Software, creators of Interarchy), is the only shareware NNTP news server for the Mac. Although this server is not really designed to handle a full modern-day (40,000+ groups) newsfeed, the software is quite powerful, and quite easy to administer. Version 1.3.4 adds/changes the following:

• Fixed a bug that broke posting to moderated groups
• Included a missing error string
• Added an "X-Trace" header
• Brought the "NNTP-Posting-Host" header into common usage standards
• Fixed a bug that could cause database compression to run at the wrong time
• Fixed a bug that could cause the log file to not be trimmed to specified length
• Fixed a set of bugs that could cause improper responses to NEWNEWS and related commands from clients
• Add uptime to daily EMails
• Fixed a number of bugs that could cause errors claiming memory was low (in the log file)
• Fixed RumorMill so that it will not POST articles to a downstream server that originally came from another server
• Fixed a bug where the ARTICLE command could return the wrong article

RumorMill requires a 680x0 or Power Mac running Mac OS 7.1 or higher (the setup application, though, requires Mac OS 7.6 or higher). The program is shareware with a fee of $90 for commercial use, $35 for private or educational use. RumorMill 1.3.x is a $15 update to registered users of RumorMill 1.2. The authors hope to carbonize RumorMill for use on Mac OS X some time in late 2002. The server portion will be ported first; the setup program will be ported later. There will be no upgrade charge to registered users of version 1.3.

Secure Shell Helper

Donationware

Current Version: 1.3 (July 6, 2007)

Secure Shell Helper (formerly SSH Admin) is a useful little utility that allows you to configure Mac OS X's command-line-based OpenSSH (Secure SHell) server application. Secure Shell Helper allows you to do the following:

• Control who's allowed to access your account
• Generate new OpenSSH keys
• View/Export your Public Keys
• Setup and Control the SSH Server
• Easy to use Wizard allows you to configure the server and personal identity

Version 1.3 adds/changes the following:

• Bug Fixes.

Mac OS X 10.1 or higher is recommended. The software is free, and the source code is available upon request, and the author does accept donations.

SHOUTcast

Freeware

Current Version: 1.9.8 (February 28, 2007)

From the SHOUTcast web site:

"SHOUTcast is a free-of-charge audio homesteading solution. It permits anyone on the internet to broadcast audio from their PC to listeners across the Internet or any other IP-based network (Office LANs, college campuses, etc.). SHOUTcast's underlying technology for audio delivery is MPEG Layer 3, also known as MP3 technology. The SHOUTcast system can deliver audio in a live situation, or can deliver audio on-demand for archived broadcasts.

"This SHOUTcast server runs on Mac OS X and Mac OS X Server 2. It is a UNIX-style app without an Aqua interface, and has to be run in a terminal window. This server should be considered beta."

Version 1.9.8 adds/changes the following:

• This release is a security fix release which fixes the Source Port password/script exploits.

SnapperHead

Current Version: 4.6

SnapperHead is an unusual and fun application that allows you to serve up captures of your screen to anyone with a web browser (not guaranteed to be compatible with Windows browsers, however). Think of it as a special-purpose web server: you simply launch SnapperHead, then send a friend your IP address (it is shown on the SnapperHead window under "Snaps Served"). When they type that Internet address into the location field of a web browser, they will be sent - as an image in their browser - a picture of your screen. That's all SnapperHead does, but it does it well. SnapperHead is absolutely free (although the author could use a donation), and is Carbonized to run under Mac OS 8.5.1 or higher, with Carbon Lib 1.2 or higher. Version 4.6 adds/changes the following:

• This version fixes a number of longstanding bugs, and is a recommended update for all SnapperHead users.

SpeedManiac

Shareware; $9.95

Current Version: 1.33

Like Muffin, above, SpeedManiac is a World Wide Web "filtering system" that acts as a proxy server to filter out content to your own specifications. However, it's not written in Java; it's a native Mac OS X application that is much easier to set up and use. While it cannot filter the variety of things that Muffin can, it is capable of filtering graphics, selected sites, and Flash animations, which is good enough for mere mortals who might not have the time to master Muffin.

In order to use SpeedManiac, you'll have to configure your Web browser's proxy settings (dig around your browser's preferences to find this) to point to the program so that it can intervene between you and the Web (which is exactly what a proxy server does). Here's how you do that:

• Open the System Preferences.
• Click on the Network icon, select your usual connection method.
• Click on lock if required, and provide your password so that you can edit the settings here.
• Click on the Proxies tab.
• Check the box for HTTP Proxy, enter 127.0.0.1, enter 1080 for port.
• Click on the Apply Now button.

Version 1.33 adds/changes the following:

• When a server was not found, we could end up connecting to the last good server again.

SpeedManiac - which is written by Ricardo Batista, celebrated author of the Extensions Manager for the "Classic" Mac OS - is shareware, and works as a trial version for 15 days.

SSH Agent

Open source; $0

Current Version: 1.1 (May 10, 2005)

SSH Agent is a graphical front-end to some of the OpenSSH tools included with Mac OS X. Specifically, it allows you to start an ssh-agent, generate identities, and add identities to an agent. Additionally, it allows you to make the ssh-agent global so that, for example, Project Builder and CVL can use it to do version control over SSH, and it has some functionality to set-up a secure tunnel.

Version 1.1 adds/changes the following:

• Conceptually, SSH Agent has changed from a window on the ssh-agent process to an ssh identity manager. This has the following consequences:
  • ssh identities are no longer treated as documents. Instead, SSH Agent's main window is a view on the identities in your .ssh directory.
  • Instead of adding identities to the agent, the interface let's you activate identities. Identities can be flagged as Default, and the preferences lets you add the Default identities when the application is launched.
  • There is an Agent Inspector which shows the details of the ssh-agent process. (It also allows you to detach the application from the process, allowing faceless operation.)
• Other changes:
  • Different preferences format. If you're only trying out 1.1 make sure you backup your nl.uu.phil.* preferences.
  • Eye candy: An animated bubble showing the number of active identities and more beautiful icons.
• Missing, incomplete, or broken:
  • The keychain interaction might be broken.
  • The version checking code is incomplete.
  • No documentation, except this page.
  • No source package yet.
  • No internationalization.

SurgeMail

Commercial; see site.

Current Version: 4.3g4 (July 23, 2010)

NetWin, Ltd. produces the industrial-strength SurgeMail "carrier class" email server that supports any number of users or domains, virus scanning, spam filtering, integrated webmail access, integrated WAP support, and fast browser based administration tools. SurgeMail supports all relevant RFC protocols: POP3, SMTP, IMAP4, LDAP, HTTP, and TLS/SSL, and has optional calendar, file sharing, instant messaging, forum, and chat room modules available.

Version 4.3g4 makes the following changes:

• Fix: (non surgeweb) Domains with mixed case domains in surgemail.ini were no longer able to login (fixed in 4.3h-30 in development branch, unsure when introduced)

TFTP Server

Donationware; $12

Current Version: 3.3.1 (September 10, 2009)

TFTP Server is a simple, free utility that helps you to use and configure the TFTP server shipped with the standard Mac OS X distribution. TFTP is a simple protocol used to transfer files, and therefore was named the Trivial File Transfer Protocol, or TFTP. The only thing it can do is read and write files from/to a remote server. It cannot list directories content or change the working directory, and currently has no provisions for user authentication, so a TFTP server must have set a dedicated working directory from which send and receive files.

With this application, you can easily start/stop the TFTP server and change the path where the files are sent and received from TFTP clients (e.g. Cisco routers and switches) which connect to your Mac acting as TFTP server. This is useful if you have a lot of network devices and want to store in a safe place all their configuration text files and operating system binary images. These files can also be reused later (as is or modified using a text editor on your Mac) to easily configure from scratch or update other similar devices.

While there is no information regarding what's new in version 3.3.1 (presumably, it's a Snow Leopard compatibility update, as it's the first new release in exactly two years), version 3.1 added/changed the following:

• Universal binary.

The NATural

Donationware.

Current Version: 1.0b2 (December 13, 2005)

From The NATural home page: "The NATural is a GUI tool to manage the NAT settings of Mac OS X Server. The NATural allows you to configure many of the settings that Server Admin will pass to natd. Apple's Server Admin software provides only a limited interface to control NAT routing functions. The underlying process, natd, can accept many more arguments. Although Server Admin does not provide an interface to these functions, it does respect all settings that natd supports." The NATural allows you to easily configure the following settings (and many others):

• Default Address
• IP Forwarding
• Port Forwarding
• Logging Options

Version 1.0b2 adds/changes the following:

• No longer asks for password twice on first launch
• Fixed interface menu to read non-physical interfaces
• Added "Other..." option in interface menu
• Fixed several "Error in helper tool response" errors
• Error messages now more specific where possible
• Now asks to apply changes if necessary before starting or restarting NAT
• Port forwarding rules must now include both a target and destination port, this is a restriction imposed by serveradmin
• Punch_fw, custom divert ports, and remote IP/port specifications of port forwarding rules now hidden (ignored by serveradmin)
• Expanded help
• Log drawer performance and memory usage improved
• Better handling of malformed port forwarding and IP forwarding rules

Tomcat

Open source; $0

Current Version: 4.1.40 (June 26, 2009) / 5.5.30 (July 9, 2010) / 6.0.29 (July 23, 2010)

Tomcat is well-known in Unix circles as a preferred Web server (often used in conjunction with Apache) that supports JSP (Java Server Pages) and the running of Java Servlets. Tomcat is actually a Java application itself (and a free one at that), and it runs quite well on the Macintosh.

Tomcat 6.0.x (for Servlet/JSP Spec 2.5/2.1) is the latest major release. Tomcat 6.0 is designed to run on J2SE 5.0 and later. In addition, Tomcat 6.0 uses the Eclipse JDT Java compiler for compiling JSP pages. This means you no longer need to have the complete Java Development Kit (JDK) to run Tomcat, but a Java Runtime Environment (JRE) is sufficient. The Eclipse JDT Java compiler is bundled with the binary Tomcat distributions. Tomcat can also be configured to use the compiler from the JDK to compile JSPs, or any other Java compiler supported by Apache Ant.

Tomcat 5.5.x remains available for Servlet/JSP Spec 2.4/2.0, and it, too, is designed to run on J2SE 5.0 and later. See the online release notes for more details.

Version 4.1.40 (for Servlet/JSP Spec 2.3/1.2) makes a number of changes, which are completely detailed in the online release notes.

Vine Server

Open source; $0

Current Version: 3.11 (October 14, 2009)

Vine Server (also known as OSXvnc) is a native VNC server for OS X that allows you to view and interact with your Mac OS X desktop from another computer over a network. Vine Server is free software and is distributed under the terms of the GNU General Public License.

Vine Server 3.11 includes the following enhancements:

• Fixed a number of international keyboards that had a small number of keys not mapped (like i and ; in French.)
• Fixed a compile level problem that caused a crash when using ZRLE encoding

An OS 9 version - called "OS9vnc" - is also available for download.

WeirdX

Current Version: 1.0.32 (April 27, 2004)

WeirdX is a Java-based, open source X Window server that happens to run successfully under Mac OS and Mac OS X. While I don't generally list Java applications on the Orchard (they're a different breed entirely, and many fine sites track Java-based software), when the program in question provides a service that Mac users find themselves wanting, I happily make an exception. Free X server software is such a beast; MI/X is good but it hasn't been updated since 1998, and XFree86 only runs on Mac OS X. Commercial alternatives exist, to be sure, but for many Mac users who need only occasional access, the pricing of these products makes them impractical. WeirdX is free (and distributed under the GNU GPL) and has a bunch of truly nice features:

• WeirdX handles X protocols directly.
• WeirdX is implemented with JDK 1.1.
• WeirdX runs as an application/applet.
• WeirdX supports Rootless mode.
• WeirdX runs as a TrueType font X Server if your JVM supports TrueType fonts.
• WeirdX supports the three mouse button emulation.
• WeirdX supports copy/paste operations between the native window system and x clients via CUT_BUFFER0.
• WeirdX supports 1bpp, 8bpp and 16bpp mode.
• WeirdX supports multibyte characters; Japanese, Korean and Chinese characters.
• JRexec is included.
• WeirdX supports XDMCP.
• WeirdX supports dxpc(Differential X Protocol Compressor) with the assistance of JDxpc.
• WeirdX includes hacks for the alpha transparency.
• WeirdX supports EsounD compatible applications.
• WeirdX includes the XJS Extension written by Christian Werner.

Version 1.0.32 adds/changes the following:

• added the secure X access support by using JSch.
• fixed a crash bug in setting the title of window frame in RootlessWM mode.
• fixed crash bugs in handling window properties.
• fixed bugs in displaying Japanese characters on recent J2SE's VM.

WeirdX supports core protocols of X11R6.3 partially, and I haven't been able to fully test it just yet. WeirdX will not be suitable to execute "heavy" X clients, but you may find that twm, xterm, etc. will run fine on it. The WeirdX home page has links to ready-to-run (double-clickable) applications for Mac OS and Mac OS X, but they may be a release or two behind the current version; if you really want the latest release, you'll have to work a bit harder. If you're running "Classic" Mac OS (i.e., not Mac OS X), begin by downloading the following files:

1. Mac OS Runtime for Java (otherwise known as "MRJ" and available on the Orchard's Helper apps page) - only if you don't already have it.
2. Apple's free MRJ Software Development Kit.
3. The WeirdX Java archive.

Once you have the two Apple MRJ products installed, you'll need to:

1. Place the weirdx-1.0.32.jar file into the place where you want it to reside permanently.
2. Drag weirdx-1.0.32.jar onto the JBindery application (located in the MRJ SDK folder under Tools | Application Builders | JBindery).
3. Enter "com.jcraft.weirdx.WeirdX" in the Class name: field, then click on the Classpath icon to make sure that the weirdx-1.0.32.jar file is in the class path.
4. Finally, using the File menu select Save As... to give it a name and save it as an application. That's it!

(Mac OS X users have it much easier: download the WeirdX Java archive, open up a terminal window, navigate to the directory where the .jar file resides, and type "java -jar weirdx-1.0.32.jar".). Paul Schaap has provided an unofficial installer for the uninitiated (1.0.31).

By the way: you'll never have to do this again; now, you'll be able to double-click on the applet whenever you want to use WeirdX. Once you have this ready, you'll need to have access to a machine that has X client applications available for running, and you'll need to use the "export" or "setenv" commands to tell this machine to use your Mac as the X Server (talk to your local sysadmin for more info.)

X11 for Mac OS X

Freeware

Current Version: 1.0 (October 28, 2003) / 1.1.3 (November 14, 2006) / 2.1.6 (May 12, 2009)

X11 for Mac OS X - from Apple itself - offers a complete X Window System implementation for running X11-based applications on Mac OS X 10.3 Panther (users of prior versions of Mac OS X should use XFree86, and Tiger users have the latest version on their installer DVDs). Based on the de facto-standard for X11, the open source XFree86 project, X11 for Mac OS X is compatible, fast and fully integrated with Mac OS X. It includes the full X11R6.6 technology, including a window server, libraries and basic utilities such as xterm.

X11 for Mac OS X takes advantage of the Mac OS X Quartz graphics system to deliver hardware-accelerated 2D and 3D graphics. Quartz provides snappy scrolling speeds for text, live drag and resize of windows, as well as 3D animation through OpenGL Direct Rendering. X11 for Mac OS X combines the display and client libraries into a single download and install, so getting X11 running on Mac OS X is easy. The installer sets up your environment with your path and DISPLAY. It also makes it simple to start xterm sessions and other popular X11 utilities. Additionally, you can use any three-button USB mouse with X11 for Mac OS X.

Version 1.0 - the latest version for Mac OS X 10.3 - adds/changes the following:

• GM v1.0: Panther compatible and included as an optional install on Mac OS X v10.3 Panther CDs.
• Bundled: Optional install from the third Mac OS X v10.3 Panther CD.
• XFree86 4.3: Includes latest enhancements from the Open Source community.
• Full Screen Mode: Show X11 root and application windows on their own screens
• X11 Dock Menu: Activate X11 applications or windows directly from the Dock icon.
• Double-click applications: Launch X11 applications in the Finder
• Application Menu Command Keys: Define keystrokes for launching X11 applications.

Version 1.1.3 - the latest version for Mac OS X 10.4 - adds/changes the following:

• This update addresses several issues in the X11 for Mac OS X package, enabling it to better handle GLX stereo visuals and offscreen rendering to GLX Pbuffers and Pixmaps.
• To tell X11 to take advantage of stereo visuals, enter $ defaults write com.apple.x11 enable_stereo -bool true
• Also addresses font issues present in X11 1.1.2

Version 2.1.6 - the latest version for Mac OS X 10.5, and available only as part of the Mac OS X 10.5.7 update (and which reports itself as version 2.0 in the Finder) - makes unspecified changes.

XAMPP

Current Version: 1.7.3 (March 5, 2010)

The "client" version of Mac OS X comes with a variety of perfectly capable open source languages, servers and utilities (such as Apache, Perl, Ruby, etc.) that comprise a comprehensive web-serving package. However, many of the versions Apple has chosen to include with "plain vanilla" Mac OS X (as opposed to Mac OS X Server) are a few versions behind the most current offerings. This makes for a stable, functional, yet somehow conservative collection of services that are missing some "bleeding edge" features that more seasoned users may have come to expect. While it's quite possible to download and use these more recent versions on your own (compilation sometimes required), it can be difficult - if not maddening - to try to keep tabs on the latest releases of all these pieces of software. Enter XAMPP, a free package from Apache Friends, which is a non-profit project to promote the Apache web server, founded in the spring of 2002 by Kai 'Oswald' Seidler and Kay Vogelgesang.

XAMPP is an easy-to-install Apache distribution containing a more recent version of the Apache web server, along with more recent versions of supporting applications such as MySQL, PHP, Perl, and more. XAMPP is really very easy to install and to use - just download, extract and start. It comes as a Mac OS X Installer package which contains all the necessary files and requires no dependencies.

XAMPP version 1.7.3 for Mac OS X contains the following software: Apache 2.2.14, MySQL 5.1.44, PHP 5.3.1, Perl 5.10.1, ProFTPD 1.3.3, phpMyAdmin 3.2.4, OpenSSL 0.9.8k, GD 2.0.35, Freetype 2.3.5, libjpeg 6b, libpng 1.2.32, libungif-4.1.4, zlib 1.2.3, expat 2.0.1, Ming 0.4.2, Webalizer 2.01-10, pdf class 009e, mod_perl 2.0.4, SQLite 3.6.3, gdbm-1.8.3, libxml-2.7.2, libxslt-1.1.24, openldap-2.3.43, imap-2004g, gettext-0.16.1, libmcrypt-2.5.8, mhash-0.9.9, zziplib-0.13.48, bzip2-1.0.5, freetds-0.64.

Please see the online installation guide before downloading.

XFree86

Open source; $0

Current Version: 4.8.0 (December 19, 2008)

XFree86 is a freely redistributable open-source implementation of the X Window System that runs on UNIX(R) and UNIX-like (like Linux, the BSDs, Mac OS X (aka Darwin) and Solaris x86 series) operating systems and OS/2. XFree86 is the underlying software that is between the hardware and graphical user interface (aka gui) that people see and use. If you are using KDE, GNOME, Enlightenment, Blackbox, AfterStep, twm or fvwm then you are already using and running XFree86 as these run as XFree86 clients.

Although Apple includes XFree86 in a special, optimized form in Mac OS X (see X11 for Mac OS X, above, for more information), this version is a little more on the "bleeding edge" and may be used on earlier Mac OS X releases as well.

The version 4.8.0 release includes the XDarwin application. Previous versions of the XDarwin application (up to v1.0.6) were available from the "XonX" site as updates to XFree86 4.1. With this addition, you can run both X Window and Aqua simultaneously - a very nice benefit. X Window on OS X has grown out of infancy into early adulthood, and that's a good thing indeed. (Thanks to Adrian Umpleby for clarifications to these descriptions.)

Xtools

Commercial; $199

Current Version: 1.2 (March 9, 2003)

Tenon Intersystems the Xtools X Window server package for Mac OS X. From the Xtools web site: "Xtools is a new, built-from-the-ground-up, object-oriented, multi-threaded Cocoa application that takes full advantage of CoreGraphics and Quartz. Xtools is optimized for the velocity engine and multiple processors and supports hardware accelerated OpenGL. Xtools is not only a vehicle for displaying remote X11 client applications, but also for developing local X11 clients. The Xtools X11 libraries let developers build clickable X applications that can be minimized in the Dock. Xtools is based on open source industry standards and is tightly integrated with Mac OS X and Apple technologies."

Zeus Web Server

Commercial; $1,699

Current Version: 4.3r4 (July 30, 2007)

Zeus Technology Ltd. produces Zeus Web Server, a scalable, ultra-high-performance (used by eBay and several other high-traffic sites) UNIX-based Web Server that now runs on Mac OS X.

ZWS 4.3r4 is a minor revision of ZWS 4.3r3, containing a number of bug fixes. Customers are recommended to upgrade as soon as possible. Changes include:

• The Bandwidth Throttling maximum number of simultaneous requests limit now applies across all ZWS processes. Previously each ZWS process applied the limit separately.
• Fix a bug where the 'connections.open' SNMP counter could return incorrect, negative values.
• The "Options" directive in the htaccess support now supports the '+' and '-' notation.
• Prevent a crash when multiple virtual servers share the same SSL certificate.
• Fix a problem where viewing the Current Connections page while SSI requests were being handled could cause a crash.
• X509 Certificate Signing Requests now use the SHA-1 hash algorithm and include the 'attributes' section (required by some certificate authorities).
• Ensure that variables set using a FastCGI authorizer appear in the environment for Java Servlets.
• Improve Perl Extension handling of connections closed early.
• Improve FreeBSD 6 kqueue support.
• PHP has been upgraded to version 4.4.7.
• Ensure 'start on boot' works correctly in Solaris 10 and the newest Ubuntu Linux releases.

Note: From 10th June 2008, Zeus will no longer support Zeus Web Server (ZWS) on several platforms, including Mac OS X. For more details, see the end-of-life announcement page.
