Perl Pop3 is a POP3 server fully implemented in Perl. The advantages over other POP3 servers are that it is not a memory hog, and can be used to connect to databases for authentication. Also, its code is easy to extend for any other uses, like POP-before-SMTP and extended logging.
SpeedySu is a modification of SpeedyCGI (a.k.a. PersistentPerl) so that it works with suEXEC-enabled Apache Web servers. Both Apache 1.3.x and 2.y running on UNIX systems are supported. SpeedyCGI speeds up Perl scripts (CGI or not) so that they remain running persistently, thus reducing the startup times of subsequent executions. SpeedySu extends SpeedyCGI by allowing ~UserDir CGI scripts started by Apache execute with the privileges of their owner user. SpeedySu contains other improvements in addition to suEXEC support.
The Kraftwurfel is a Linux-based appliance server for use in small organisations, which can be administered with an easy-to-use and good-looking Web interface. The focus of the administration interface is to offer a good chosen subset of the service's features to the administrator. Behind the surface of the Web based administration and user interface is an expandable software architecture build around a database, which holds the all configuration information.
percomoni will monitor one or more processes. It can read a regular expression from its configuration file to look up the process in your local process table. If the process is not running, percomoni will execute a given command and re-check if the process is up again. If the process is not up after executing the command, an email message will be sent to the address that belongs to that process.
