Hello, I have been monitoring an LTSP 4.1 client (runlevel 3) to see what network traffic is involved. I have put into our rc.local a 'remount' of the root file systems to include the 'noatime,nocto,actimeo=3600' options as there seems little point in too much checking of attributes for a read-only file system.
However, using tcpdump I can see NFS ACCESS calls going from the client to the server every 5 seconds or so: 15:17:47.923542 IP 141.163.60.56.280810905 > 141.163.66.135.2049: 88 access [|nfs] 15:17:47.923908 IP 141.163.60.56.297588121 > 141.163.66.135.2049: 88 access [|nfs] 15:17:52.923582 IP 141.163.60.56.314365337 > 141.163.66.135.2049: 88 access [|nfs] 15:17:52.923939 IP 141.163.60.56.331142553 > 141.163.66.135.2049: 88 access [|nfs] 15:17:57.923623 IP 141.163.60.56.347919769 > 141.163.66.135.2049: 88 access [|nfs] 15:17:57.923970 IP 141.163.60.56.364696985 > 141.163.66.135.2049: 88 access [|nfs] 15:18:02.923663 IP 141.163.60.56.381474201 > 141.163.66.135.2049: 88 access [|nfs] This shows just the client->server traffic, but the server does send a 'reply ok' packet back too. I understand that ACCESS call results are not cached in 2.4 kernels (but are in 2.6), but cannot think why the client is sending an access call? What is it trying to access? The client is not doing anything but sitting there at the bash prompt. There is no nfs swap configured.
