- *************************************************************************
- You need the following software installed on your system:
- - perl 5.003
- http://www.perl.com/perl/info/software.html
- - MRTG 2.1
- http://www.ee.ethz.ch/~oetiker/webtools/mrtg/mrtg.html
- - gcc to successfully compile tcpblast.c
- *************************************************************************
- mrtg-blast has been tested successfully under:
- Linux 2.0.25 (S.u.S.E. 4.3)
-
- (other versions / OSes might work, but have not been tested.)
- -------------------------------------------------
- The latest version should always be available from
- ftp://ftp.inside.ch/pub/mrtg-blast
- If you create a new version, please send it to me so I
- can keep the archive up to date.
- *************************************************************************
- YOU NEED TO CHANGE THE FOLLOWING:
- tcpblast:
- 1 - Type 'make tcpblast' to compile the tcpblast executable
- 2 - Copy tcpblast to your mrtg binary directory
- In mrtg-blast:
- 1 - Line 1: Adjust perl path to your system
- 2 - Line 55: Adjust tcpblast path to where you put tcpblast
- 3 - Copy mrtg-blast to your mrtg binary directory
- Edit your mrtg-blast.cfg file to add statements for the devices you want to
- blast. See mrtg-blast.cfg for an example.
- PLEASE NOTE: Blasting causes traffic, which it inherently does. ;) So please
- don't flood the whole wide world, keep it as local as possible.
- Blasting can't be that bad though, considering internet radio and tv... at least
- it tells us something: How fast our next video conference will pass, for example.
- The program returns traffic estimates which can be off sometimes. Use with care,
- caution and much love.
- Here are some estimates I tested at our site locally. Your mileage will most
- definitely vary, but as a guideline I always use 500 packets if I'm close to
- the site being blasted otherwise 200 is good enough.
- Link: 256 kbps = 32 kB/s
- #of packets: bandwidth as estimated
- by tcpblast [kB/s]: Error in %:
- 100 50 +53 %
- 200 38 +16 %
- 300 35 +5 %
- 400 34 +4 %
- 500 32 0 %
- 800 32 0 %
- You should decide yourself how accurate you're trying to be. Once again:
- Your mileage will vary.
- Have fun!
