Usermin is a Web interface that can be used by any user on a UNIX system to easily perform tasks like reading mail, setting up SSH, or configuring mail forwarding. It can be thought of as a simplified version of Webmin designed for use by normal users rather than system administrators.
Saswire is a Perl program which generates a database in SDBM format containing the modification time, MD5 checksum, size, and creation time for a list of files specified in a input file. It is designed to check for unwanted modifications of Unix system binaries if security is compromised.
The NET-SNMP (formerly UCD-SNMP) package contains various tools relating to the Simple Network Management Protocol including an extensible agent, an SNMP library, tools to request or set information from SNMP agents, tools to generate and handle SNMP traps, a version of the unix 'netstat' command using SNMP and a Tk/perl mib browser. It was originally based on the Carnegie Mellon University SNMP implementation (version 220.127.116.11), but has been greatly enhanced, ported and fixed and barely resembles the original package anymore.
Usermin For Webmail is a modified version of the Usermin package that is pre-configured for use as a Web-based email client. It is designed to work on systems running a local IMAP server, such as Dovecot. By default, users can read email, setup autoresponders and forwarding with Procmail, filter mail with simple rules, change their passwords, and manage folders.
SpamCheetah is a network-level spam filtering solution built around OpenBSD greylisting, tarpit, and blacklisting. It comes with a Web interface and requires zero administration. It does not allow spam to even land in your network, thus saving you precious bandwidth. It does not have the 'false positives' problem of losing legitimate mail.
Many project are mirrored worldwide. Mirmon helps in monitoring these mirrors. In a concise graphic format, mirmon shows each site's history of the last two weeks, making it easy to spot stale or dead mirrors. Mirmon quietly probes a subset of the sites in a given list, writes the results in the "state" file, and generates a Web page with the results. The package includes a Perl module called Mirmon.pm; this makes it easy to write applications related to mirmon.
