[...] Does this mean that your infrastructure enforces the use of DHCP-renewals, or could you also stick with the IP address you obtained once? In this case I'd suggest that you build a static IP configuration from the data obtained from DHCP (hmm, may be stupid, probably the code does this anyway). On the other hand, your hangs: Could it be that your client gets a different IP from DHCP at some point? I guess NFS is pretty much unhappy with that... Best, Michael
