NFS and RPC timeouts

[Nathan Smith <nsmith@poinciana.uttyl.edu>]

Hi,

Sorry if this has been answered here before, I tried looking in the
archives and came up with nothing.  I'm trying to run NFS and have
everything set up correctly on both client and server sides (according 
to the HOWTO and man pages), at least as far as I can tell.  However,
when I'm on the client and try to mount a filesystem by hand (not at
boot-time via fstab, which I haven't tried yet since I can't get it to
work by hand), I get 

mount: RPC: Timed out

I'm assuming that something is going on on the client side in that it's
not waiting long enough to hear back from the server.  Is there a way that 
I can get the client to wait longer?  The pause is about 15 seconds by
the way, and PING averages 0.6 ms between the 2 machines.

Thanks in advance for any help,

Nathan Smith
