queue-admin is a bash2 shell script for managing the mail queue of the qmail MTA. It can provide a summarized list of the messages in the queue, optionally filtered by number or by whether a message is local or remote. The messages themselves can be listed, viewed, or deleted by the same criteria. It can also search for expressions within the messages, and can return the entire email or only the line where the expression was found. The output is colorized.
@1 Helpdesk XP Perl is a very powerful Web-based helpdesk system. It supports file attachments, hidden remarks, priority marking, etc. Unlike other similar products, this script does not use the conventional "assign/completed" method to close past tickets. Instead, it uses an intelligent method to sort/rank inquiry tickets. You can even tell whether your replies have been read by the visitors.
p-run is a utility that runs a program, script, or series of commands on a large number of hosts in parallel. It simplifies management of machines in computer labs. It uses ssh, and supports password and key-based authentication. p-run uses libexpect, and will run in parallel across as many processes as specified. When run on a large number of hosts, its parallel nature significantly speeds up administration.
Kernel Security Checker is a useful tool to locate attackers residing within a system by employing a direct analysis of the kernel through /dev/kmem and bypassing the hiding techniques of the intruder (kernel static recompilation or use of LKMs). It can find the modified syscalls from userspace, detect the promiscuous interfaces, and find the modifications applied to a protocol.
