This is a small utility which will help you test whether a syslogd (or syslog-ng, or others) really works when listening on a UDP port for incomming log messages.

poplimitd is a daemon process that will monitor your server maillog file for POP3 or IMAP connections. Using configurable settings it monitors the rate of logins based on user account and IP address. If it finds excessive usage, it will send a preconfigured email with the users information to that user asking them to stop it. In the future it will also have the option to block the IP address. On servers that suffer from high POP3/IMAP load, this can dramatically modify user behaviour and limit POP and IMAP connections and load.

IP Accountant allows you to keep an Rx/Tx byte count for each address aliased to a single interface. It features optional graphical output.

Syslog2 is a realtime parser and event handler for syslogd. An event is a message from some service. It uses a simple plugin system to add event handlers. Syslog2 is written in Perl. A plugin is simply a Perl script which invokes the "register_handler" or "unregister_handler" subroutines. By default, the package uses the included script "default.pl", which logs all messages from the syslog daemon in sorted order. More scripts are available from the homepage.

A simple Perl script which monitors system load and if the load is higher than a specified amount, it performs user-defined commands in an attempt to lower the load. Once the load has returned to a normal level (also user-defined), it will perform another set of specified commands to bring the server back to normal. This script also can connect to an Eggdrop bot to announce problems with the server load in real-time.
