[rhn-users] NFS over TCP

[Charith Perera]

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?
