Have you read the FAQs about NFS server with Sun clients? 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).
