Advisory Check is a program that reads security advisories for you. It gathers security advisories using RSS, RDF, or XML feeds, compares them against the installed software, and alerts you if you're vulnerable. A wide variety of package managers can be queried to detect installed software. Remote systems can be monitored by using the integrated SSH, Windows-RPC, and Nmap support.
Alerttail monitors a given file and executes a list of actions when a user-defined text pattern has been written to the file. For example, the user can pop up a GTK notification window when a certain message is written to a log file. Actions can be alerttail built in actions (GTK notify action, geoipLocalization action, or filtering text action) or a custom user defined shell command action. A Qt 4 GUI frontend helps with configuration.
Aranha is an application that uses an XML-RPC layer to retrieve information from one or more servers. The type of information gathered is implemented via plugins, and can be displayed or archived in several different ways. The data is gathered in Round Robin Databases (integrated with rrdtool) and can be accessed using a XUL interface available from the system. Plugins are very easy to write.
Blogbench is a portable filesystem benchmark that tries to reproduce the load of a real-world busy file server. It stresses the filesystem with multiple threads performing random reads, writes, and rewrites in order to get a realistic idea of the scalability and the concurrency a system can handle.
BulkWatch is a utility that monitors sendmail's logs and takes a specified action when an IP has exceeded your configured maximum settings. You can specify that users may send X messages in X number of seconds. Email in excess of that would trigger an action, which can be any of the following: display an alert to the screen in foreground mode; log an alert to syslog; email an alert to a predefined email address; or run an external command with the IP and number of messages as arguments.
CD-ROM Digest is a program that checks a multi-track CD-ROM. It reports the MD5 digest and size for each track on a CD-ROM. The digest is done as the track is read, without dumping CD-ROM data on the hard drive. This tool helps users that are burning a multi-track CD-ROM to check the result.
