MAT is an easy-to-use network-enabled UNIX configuration and monitoring tool. It provides an integrated tool for many common system administration tasks, including backups, replication, and running commands on hundreds of machines at once. It includes a warning system for potential system problems, and graphing of many common system parameters. MAT provides many of the tools a system administrator needs during the day, including DNS, NIS, Backups, and Replication. One can run a MAT command on many hosts at once. A simple editor window is provided which can modify a set of machine's configurations in one session.
CD-R/W discs can be written with a technique called packet or incremental writing. This allows transparent and buffer-underrun-free recording for CD recorders that support this method. No more mastering of .iso images; just mount your CD-ROM read/write and copy files directly to it.
changedfiles is a framework for filesystem replication, security monitoring, and/or automatic file transformations--essentially any application where you'd poll files or directories and either do something to them or send them somewhere else (or both). The difference is that the kernel tells you when they change instead of you having to poll. It's an easy real time FTP push mirror to one or multiple sites. It's also a full fledged MySQL client, so you can do realtime database operations (for example, batch imports). It consists of two parts: a kernel module (works with Linux kernel version 2.4) which reports to a device whenever a file on the filesystem changes, and a daemon which runs in user space and can be configured to do almost any action when a change to a file matching the one of the patterns it looks for is reported. The kernel module is SMP safe and has been tested on Intel, PowerPC, and Alpha.
amandalogp is a package whose goal is to facilitate the interpretation of the logs and reports produced by Amanda (the Advanced Maryland Automatic Network Disk Archiver). It will parse the mail sent by Amanda (typically as a procmail filter) and send a colorized HTML version of that report which helps monitor a specific set of machines of special interest to some admins.
Userexitd for TSM is a configurable handler for Tivoli Storage Manager events. It allows an administrator to filter events using regular expressions and run various actions for TSM events, such as sending mail and SNMP traps, writing messages into syslog, and running scripts and programs. This software consists of two parts: a simple shared library (userexit.so), which is dynamically linked to the TSM Server as a user exit and communicates using a socket with the userexitd daemon, which runs as a separate service. The daemon is configured with an XML configuration file.
Network Device Change Control (NDCC) is a system that monitors and records changes to the configurations of network equipment. It can store configuration snapshots for any text-based configs. It has been used to store configurations from Unix and Linux systems, Cisco routers, switches, load balancers, and firewalls, Foundry, NetScreen, Juniper, NetScaler, and others.
