I'm not certain what an RPC connection is, but I assume it's some type of flow of data. Nothing referring to RPC appears in either machine's logs. Not a lot of activity occurs on the file server at 192.168.0.244. It's primary purpose in life is to act as a file server for the machine at 192.168.0.252, which is the machine having difficulty connecting. It's worked flawlessly for years. The time-out problem is something that's appeared in the past week. I'm using a stale version of FreeBSD, but why would that cause mount_nfs to suddenly start timing out? ------- At 04:52 PM 4/20/2010, Jon Mercer wrote: >Do you have anything relating to RPC connections inbound on the server logs? > >It may also be time to look at which version of FBSD you are running. > >On 20 April 2010 19:06, <peter@vfemail.net> wrote: > >> >> I deleted the unnecessary line from the /etc/exports file and rebooted both >> machines.
