Many thanks for any pointers! please don't crosspost but, if you're saying FreeBSD can NOT do tcp mouting of a Solaris NFS server: -mount xxx:/scratch on /mp3 xxx:/com on /com -fstab xxx:/com /com nfs intr,-a4,rw,tcp,bg,nfsv3,-r32768,-w32768 0 0 xxx:/scratch /mp3 nfs intr,-a4,rw,tcp,bg,nfsv3,-r32768,-w327680 0 -netstat tcp 0 0 bright.1021 xxx.2049 ESTABLISHED tcp 0 0 bright.1022 xxx.2049 ESTABLISHED (trafshow also shows the trafic when doing NFS activity going over a tcp socket) This is 3.0 however, maybe i confused your terminology. -Alfred > > Regards, > - Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
