pyNMS is a set of Python modules for network management, network testing, systems management, and general use. It contains a nearly complete implementation of SNMPv2c, a SMI/MIB package, and a MIB "compiler". There are many others, such as a telnet/console access class, XML tools, an IPv4 class, etc. There is, unfortunately, little documentation, and not everything works properly yet, but they work well enough to be useful for many things.
Hep Message Server is software that transfers messages between different messaging systems. Eventually, it should transparently route messages between email, weblogs, and instant messaging. Currently Hep does one thing: fetches news feeds from Web sites and lets you view them in your email client.
cgi_buffer is a group of libraries that may be used to improve performance of CGI scripts (and other content generation engines) in some circumstances by applying performance-enhancing HTTP mechanisms that are typically not supported by them. Currently, Perl, Python, and PHP4 are supported. The Python library may also be used as a wrapper around another CGI script.
Python-LZO provides Python bindings for the LZO data compression library. You can access the LZO library from your Python scripts thereby compressing ordinary Python strings. LZO is a portable lossless data compression library written in ANSI C. It offers pretty fast compression and *very* fast decompression. Decompression requires no memory. In addition there are slower compression levels achieving a quite competitive compression ratio while still decompressing at this very high speed.
