I have developed myself a similar setup, but i used a perl script with=20
snmp pass_persist to retrieve the data via snmp feed it to MRTG and then =

display it with a CGI script, since i changed jobs recently i made some=20
changes to the setup and was thinking in creating a sourceforge project.

But i don't think it is ready for that yet, i mean, it is working=20
beautifully for me (and in my previous employer) but there are some=20
rough edges to address first.

Btw, the setup generates TC, iptables and MRTG configuration from a=20
config file.

I think it is time to see how can the setup be improved.

I really never tried to write a better tool, with less 'tc -s' parsing,=20
don't have the time or incentive to hack the needed code, so can't help=20
