sudosh can be used as a default login shell or a filter that takes advantage of PTY devices in order to sit between the user's keyboard and a program, in this case a shell. It was designed specifically to be used in conjunction with sudo, and allows the execution of a root or application shell with logging. It is basically a VCR and will record root shell sessions and also has the ability to play back the sessions as they were originally recorded. It records all input/output, keyboard input, and timing information so that the session can be played back in the original format.
svclean is a set of utilities for enhancing svscan and supervise. With these tools, you get clean shutdown (i.e. services are guaranteed to be stopped before their loggers, so no logs are lost) and supervised logging of svscan's and supervise's output (so if the last-resort logger is killed, it can be restarted). These features are practically necessary for running svscan as process 1, but are useful even when svscan does not run as process 1.
svncommit_hook.php was written to address the numerous problems with the commit_email.pl script which is bundled with subversion. Email messages sent by this script are sent as multipart messages with each diff in its own part. All of the parts are sent as nicely formatted HTML. It is possible to specify the charset of the files in the repository (the default is still UTF-8). Diffs are displayed only for the modified files. Diffs are colored. PHP files are validated with "php -l". It is possible to specify the URL of a corresponding Trac-resource, and the links to the files will be automatically included in the email.
sysklogd-sql is a port of the sysklogd daemon that can log data to a MySQL or PostgreSQL database running either on the same machine or a remote database server. The SQL configuration is done in the standard syslog.conf file for easy administration and configuration. Also included is a set of sample PHP scripts to query the data from the syslog database. In a large environment, you can set up a central logging server, or configure a secure syslog environment that will make it very difficult to tamper with the syslog data.
syslog-ng is a syslogd replacement for a wide variety of UNIX systems that supports IPv6 and is capable of transferring log messages reliably using TCP and SSL and filtering the content of messages using regular expressions. Both RFC3164 and RFC5424 style messages are handled, but more esoteric formats like BSD process accounting logs are supported too. Apart from regular text files, it supports storing messages into SQL and MongoDB databases, and forward messages to local processes via pipes or UNIX domain sockets. This makes syslog-ng ideal as an integration platform. syslog-ng supports extracting structured information from the traditionally text based syslog via csv-parser(), db-parser(), and patterndb. Tag based classification, rewriting messages, and outputting messages in JSON is also possible. This makes syslog-ng ideal for preprocessing events for further analysis, be that home-grown scripts or SIEM systems. syslog-ng scales well on today's multi processor and multi-core systems: reaching 1,000,000 messages per second is a reality for the simplest use cases.
