Subject:   amd / multi-homed nfs servers - not responding?
Message-ID:  <3C22650F.95482042@centtech.com>

Ok, this is a weird issue I'm having with FreeBSD clients (4.2, 4.3).  I have a
FreeBSD client on net A, and a multi-homed NFS server (running Linux, or
Solaris, take your pick) on nets A and B.  If I attempt to access the server
with automounter (amd) via the interface that is NOT on my net (A), it times
out, responding with:
nfs server pid226@clienthostname:/net: not responding
nfs server pid226@clienthostname:/net: is alive again
ls: /net/inside/usr2: No such file or directory

It only seems to happen with NFS servers that have a NIC on the same net as the
FreeBSD client AND a NIC on a different net.  

Also, this may be unrelated, but it's still odd (and probably somehow
exploitable).  Hard to explain, but I'll do my best. 
If, on a client, I try to do a 'cd /net/server1/' to a NIC (on the server) that
will timeout (as mentioned above), and as soon as it starts timing out, I do
ctrl-C to break from it, and open another window and do a 'cd
/net/server2/share/', when the first 'cd' command finally breaks, it will drop
to a /net/server2/share/ directory, instead of the original working directory..
So it sounds kind of like the NFS handles are being reused too quickly or
something like that.

Anyone have any ideas?  Anybody seen this? 

Eric
