The default showed up as a nfsv3 mount: 1/25 2:12 mountd/v3: granted 192.67.166.79 to /bob ro=0 uid0=60001 The solaris mount showed up as: 1/25 2:06 mountd/v3: granted 192.67.166.155 to /bob ro=0 uid0=60001 1/25 2:06 nfs/tcp accepted 192.67.166.155,1023 I'll try an explicit v3 mount/tcp and see if it's better.
