MailScanner is a complete e-mail security system designed for use on e-mail gateways. It protects against viruses, and detects attacks against e-mail client packages (such as Outlook, Outlook Express, Eudora). It can also detect almost all unsolicited commercial e-mail (spam) passing through it and respond to all incidents in a wide variety of ways. Not only can it scan for known viruses, but it can also protect against unknown viruses hidden inside e-mail attachments by refusing entry to attachments whose filenames match any given pattern. This can include generic patterns that trap filenames attempting to hide the true filename extension (e.g. ".txt.vbs"). It is superior to many commercial packages in its ability to handle attacks against itself, such as Denial Of Service attacks caused by messages containing the "Zip of Death". It is easy to install into an existing e-mail gateway, requiring very little knowledge of sendmail and no change to an existing sendmail configuration. MailScanner itself is entirely open source, but it uses widely known commercial virus scanning packages at its core. The other software it uses is all high quality open source software, leading to a system that can be trusted for performance and reliability.

Nearly all of today's mail system administrators face spam as their first threat. Because of this, EnderUNIX team has written this small application to automagically monitor malicious spammer activity in your mail server logs. spamGuard is written purely in C, to stop spammers hanging around. The program supports nearly all mostly used MTAs; qmail (both multilog and splogger), sendmail and Postfix.

snoopy is merely a shared library that is used as a wrapper to the execve() function provided by libc as to log every call to syslog (authpriv). System administrators may find snoopy useful in tasks such as light/heavy system monitoring, tracking other administrator's actions as well as getting a good 'feel' of what's going on in the system (for example Apache running CGI scripts).

Ambit, at its simplest, uses Bash Brace Expansion to expand and list hostnames OR commands. First and foremost Ambit is meant to be a general purpose hostlist enumerator to be used by other applications or scripts. Additionally Ambit can be used to manage User Specific as well as System-Wide HostGroups. It can also be used to query Network HostGroups. Finally, Ambit is able to detect when it is expanding a command (rather than a host list), allowing for the command to be expanded and executed synchronously. This means Ambit can expand and run just about anything on the command line and usually works in places where Bash Brace Expansion might fail.
