Re: Bandwidth measuring tool
Hello,
I think your question is twofold:
a) Generate Traffic
Have a look at the kernel module "pktgen". It creates UDP only IIRC, but
the kernel has to do forwarding decisions per packet, so it's a quite
good way to test a machine. You can saturate a GBit Link with that tool,
as it works "below the stack"
b) Measure Traffic
Well, many tools and ways exist. Examples
cmdline tools:
- iptraf
- bwm
collecting daemons
- snmpd
- sysstat (?)
GUIs/Frontends:
- Cacti
- OpenNMS
- MRTG
- RRD Tool
And, as Wojciech already posted, there a measurement tools like iperf.
'apt-cache search traffic' will shoe you lots of options. Personally I
would go for a "snmpd + Cacti + pktgen"-solution and probe traffic +
resource usages.
Keep in mind that "Traffic != Traffic". Usually it's more important to
check how much packers per second you machine can handle.
rgds,
Andreas

does anyone know a bandwidth measuring/test tool?
I have to produce more than 150Mbit.
