KOSd is a modified version of Ascend's RADIUS (derived from Livingston's) daemon that supports GECOS password files in another location than /etc/passwd. The path to the file is configurable in a C file. It's great for segmenting dial-in and email-only users on a dialing pool, supporting both Max units and Xylogics (now Bay) servers from a single password file, and probably others. It will probably work with Cisco or Livingston servers as well by changing the dictionary file and turning off the -DASCEND extensions within the makefile, but you may need to experiment. This product is totally unsupported.
clockspeed uses a hardware tick counter to compensate for a persistently fast or slow system clock. Given a few time measurements from a reliable source, it computes and then eliminates the clock skew. sntpclock checks another system's NTP clock and prints the results in a format suitable for input to clockspeed. sntpclock is the simplest available NTP/SNTP client. taiclock and taiclockd form an even simpler alternative to SNTP. They are suitable for precise time synchronization over a local area network, without the hassles and potential security problems of an NTP server.
mess822 is a fast library for parsing Internet mail messages, with several qmail-compatible applications. It supports the full complexity of RFC 822 address lists and common RFC 822 extensions, and extracts each address as an easy-to-use string, with a separate string for the accompanying comment. mess822 also converts RFC 822 dates into libtai's struct caltime format, with support for numeric time zones, the standard old-fashioned time zones, and many nonstandard time zones.
