Re my question yesterday about having an nfs mount hang from freebsd 2.1 to solaris. It clearly has nothing to do with the particular device card, since the card in question is a PCI smc 100mbit card on a p-90 computer and we are talking about reacting in time to an NFS ACK which is not exactly a big packet. I'm not sure that my answer is IT, but it works and scarier, might make sense, not sure. To refresh the collective consciousness, I would do a # mount -o -P solarisbox:/somewhere /here and the mount would succeed, but then a # cd /here would hang. tcpdump showed that freebsd was getting the NFS ack from the solaris box back ok, but was for some reason rejecting it with a icmp port unreachable error. SO, I tried: # mount -o -cP solarisbox: etc ... The man page for mount_nfs says that -c means: "for UDP mount points, do not do a connect(2), This must be used for servers that do not reply to requests from the standard port number". Now to see if this will actually work reliably enough that I can put it in /etc/fstab and is not just a matter of timing. regards Jim Binkley jrb@cs.pdx.edu
