Yeah I saw that. But if you do a "rpcinfo -p" on the server I get the
following:
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 32768 status
100024 1 tcp 32768 status
100021 1 udp 32769 nlockmgr
100021 3 udp 32769 nlockmgr
100021 4 udp 32769 nlockmgr
391002 2 tcp 35414 sgi_fam
100011 1 udp 847 rquotad
100011 2 udp 847 rquotad
100011 1 tcp 850 rquotad
100011 2 tcp 850 rquotad
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100005 1 udp 45112 mountd
100005 1 tcp 35691 mountd
100005 2 udp 45112 mountd
100005 2 tcp 35691 mountd
100005 3 udp 45112 mountd
100005 3 tcp 35691 mountd
As you can see, nfs is listenering only on UDP, and not TCP. So I assume that
this means the server is only serving UDP connections. Am I wrong?
