MP3 Diags finds problems in MP3 files and helps the user fix many of them. It looks at both the audio part (VBR info, quality, normalization) and the tags containing track information (ID3). It has a tag editor, which can download album information (including cover art) from MusicBrainz and Discogs, as well as paste data from the clipboard. Track information can also be extracted from a file's name. Another component is the file renamer, which can rename files based on the fields in their ID3V2 tag (artist, track number, album, genre, etc.).
Dr. PortScan is a tool for the automatic analysis of port scans in large and complex network infrastructures. The differences between successive scans of a network can be sent as reports at regular intervals to predefined admins. It uses port scans generated with nmap by default.
The stad (short for SMB Traffic Analyzer Daemon) program collects incoming data from the vfs_smb_traffic_analyzer VFS module included in Samba 3.2.0 and later. Of the received data, it builds an SQL store that can be queried. The SMB traffic analyzer software suite is a toolset aiming at visualizing the data flow on one or more Samba servers, providing statistics about the usage of Samba services. The long term goal of the SMB Traffic Analyzer project is to provide a universal remote debugging facility for Samba.
DynaBlast is a fast Apache HTTPD access_log scanner. It can find hosts that exceed a given number of hits in a given time period, printing them to standard output. It has a "fast mode" that can skip lines that have already been parsed. Multiple dynablast instances are avoided by using a lock file. This make it suitable for crontab usage. It can be run by any user, not just root. It can run in parallel, for example, when analyzing different access_log files. It keeps memory consumption down to about 10 kb, by parsing the access_log file one line at a time.
