Re: [SLE] NFS in V 10 and Apple OS

Hi,
I'm also having a few problems with NFS on SuSE 10. I am trying to mount
resources from a SLES 9 machine, presumably set up for nfsvers 3???
Each boot time, I get the error message that the "server reports TCP
unavailable, resorting to UDP". I also occasionally see error messages
to the effect of "server reports nfsvers 4 not available, switching to
version 3".
All in all, it means that each time I reboot my SuSE 10 machine, I have
to log in as root and issue the command: mount -vat nfs, and more often
than not this will pick up the nfs drives that aren't being mounted at
boot time.
FYI, here's the lines from /etc/fstab:
163.1.82.28:/home /home nfs
rsize=8192,wsize=8192,intr,bg,nfsvers=3 0 0
163.1.82.28:/home1 /home1 nfs
rsize=8192,wsize=8192,intr,bg,nfsvers=3 0 0
163.1.82.28:/home2 /home2 nfs
rsize=8192,wsize=8192,intr,bg,nfsvers=3 0 0
What are the implications of using UDP and nfsvers=2 on
security/performance etc.????
Anyone know what's going on? I have another AMD64 machine (SuSE 9.3),
which has exactly the same problem.
Best wishes,
Jon.
