Hello.
I am facing some strangeness from SunOS/sparc clients, mounting users
home directories on a FreeBSD 4.6 server. The client is unable to
mount the remote directory.
On the server "pave", a tcpdump with the host "geny" gives :
...
18:19:30.110221 geny.0 > pave.imag.fr.nfs: 0 null (DF)
18:19:30.110403 geny.0 > pave.imag.fr.nfs: 0 null (DF)
18:19:33.480054 geny.0 > pave.imag.fr.nfs: 0 null (DF)
18:19:40.230062 geny.0 > pave.imag.fr.nfs: 0 null (DF)
18:19:53.730234 arp who-has pave.imag.fr (Broadcast) tell geny
18:19:53.730252 arp reply pave.imag.fr is-at pave
18:19:53.730750 geny.0 > pave.imag.fr.nfs: 0 null (DF)
18:20:20.730172 geny.0 > pave.imag.fr.nfs: 0 null (DF)
...
The SunOS client hangs, waiting for the FreeBSD server :
Oct 16 18:18:28 geny nfs: [ID 664466 kern.notice] NFS fsinfo failed for server pave:

Running snoop on the client gives :

Any idea to lockout situation ?
Thanks.
