Yes. The FreeBSD Server only accepts NFSv2 mounts (using the -2 flag
on mountd). NFSv3 was said to be too unstable to use in a production
system. The system specs are as follows:
PII-300 w/ 128M RAM
Adaptec aic7880 Ultra SCSI host adapter
Intel EtherExpress PRO/100+ card.
3COM hub
The card is:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 206.29.49.78 netmask 0xffffff80 broadcast 206.29.49.127
ether 00:a0:c9:ce:ea:4a
media: autoselect
The one problem seems to be:
[vshah@hal] ~/extraspace> netstat -i | more
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
fxp0 1500 <Link> 00.a0.c9.ce.ea.4a 43972311 183 43193398 2 1842570
fxp0 1500 206.29.49/25 hal.rstcorp.com 43972311 183 43193398 2 1842570
There seem to be a lot of collisions on the card. Is this indicative
of anything? Should the NIC be forced into 100baseT/full-duplex mode?
The 100Mb segment only has a couple of Ultras, the FreeBSD server and
a couple of NT boxes on there (basically all the different server type
boxen).

The Solaris server is an Ultra-1 without any RAID.
