sFlow format diagrams

the sFlow version 4 packet format is described in RFC 3176 and the current version 5 in a memo. in addition to that there are format diagrams for both versions available: v4 diagrams, v5 diagrams.

sFluxDebug.pl

sFluxDebug.pl is a script based on the module Net::sFlow, which simply prints sFlow data to STDOUT. It can either read a .pcap file or receive sFlow datagrams via an UDP socket. It is very handy for debugging purposes, or as an example how to use Net::sFlow.

Net::sFlow

The PERL module Net::sFlow provides a mechanism to parse and decode sFlow datagrams. It supports sFlow version 2/4 and sFlow version 5. The current release version is 0.11. A decription of how to use the module and what kind of data it provides can be found here or on CPAN. A few Debian packages are available here.

growlThunderbird

David LaPorte wrote a script which notifies you about incoming e-mails in thunderbird via growl. you need the thunderbird extension yamb to define an "external notifier executable" as in growlnotify, which is a commanline interface to growl. unfortunately growl crashed every time i've got more then 10 mails because every email was handeled seperately. so i wrote an really ugly workaround growlThunderbird. see the README in the .tar.gz for more details.
