perfSONAR User Q&A and Other Discussion

[Joseph Ghobrial <>]

Hi, has anyone setup a perfsonar box with 2 NICs in the same subnet? I’m 
trying to get my kernel routing rules correct along with what I believe is 
necessary for the /proc/sys/net/ipv4/conf/*/rp_filter kernel options.

The issue I’m trying to resolve is my wanting a latency testing NIC with a 
separate throughput testing NIC and have the traffic correctly enter and 
leave the respective NIC. Right now the traffic obeys the default gateway 
rule for some reason even though I’ve specified what I believe is the correct 
combination of rules to get things working with each respective NIC.

This is probably pretty terse and I’m not sure if a supported configuration.

Thanks,
Joseph
