If you just want to see how much data you can get it to route through how fast, iperf is a good "quick and dirty" test method. put a box behind eth1 and one behind eth2, run iperf in server mode on one, and run a client on the other and see what kind of throughput you can get. Dont forget to adjust the concurrent threads, you'll be disappointed by the results from a single thread...

If you want more comprehensive performance testing, do as Stig suggested and check out ixia or spirent.

Hi Everyone

Thanks to this forum, I have been able to set up a network with a vyatta router at its center ( having eth0 eth1 and eth2 ) connected to the internet via eth0 and to two separate LANs through eth1 and eth2 respectively. the LANs are able to communicate with each other and with the WAN as well via the vyatta router .

Now I want to do a performance analysis of this router . Can i get a detailed step by step documentation of how i can go about this ? How do i view the packets that are flowing through the router ? is there a thing like Wireshark in vyatta ?

It would be great if someone can help me out with this issue.

Thanks and regards
Saptarshi
