I am doing a case study at my university and I am trying to analyze packets for LNET. I want to compare this with other Network based filesystems, such as NFS and SMB. I plan on using tcpdump to get capture LNET packets, but I am not sure what port I should listen to. Does anyone know what port Lustre runs on? TIA

There are some tcpdump patches floating around somewhere to do some level of LNET protocol decode that you might be interested in. b. -------------- next part -------------- A non-text attachment was scrubbed...
