Re: [Sheflug] NFS the hard way
Hi Guennadi,
Unfortunately, when I try 'rpc.mountd' I get the error message
"Network is unreachable" i.e. The same error message that I get when
I try 'rpc.nfsd' or 'nfs start'. I suspect that there's some
precursor to mountd which I haven't activated, or my ifconfig-ing
(detailed below) lacks some crucial parameter.
Please keep the suggestions coming - I'm a desperate man!
Cheers,
James
