hmm.  I see the same thing on my wireless routers, and I can't see how to
configure that - it should happen in /etc/network/interfaces - which _is_
set to send a hostname.

Ah.  man interfaces tells me some DHCP clients won't use the values from
interfaces... time to submit a bug report on dhclient3.  "send ..." does
the job.

Can't see why not.  You are trying to use a fully-qualified domain name,
right?  What does dig tell you about Foo?  In my case, trying to nfs mount
something from the linux router running the dhcp (saxon.pointerstop.ca)
server gives me "connection refused" - which is not unexpected - and from
the other linux router - which I haven't been able to get into saxon's DNS
for probably exactly the same reasons - "mount: can't get address for

So, mounting from my own system onto the same system via nfs now gives me:

derek at othello:/tmp$ sudo mount -t nfs saxon.pointerstop.ca:/usr/local /tmp/x
mount: RPC: Remote system error - Connection refused

so it would seem that once I got it into saxon's DNS I was over that hurdle.

I still think that samba mounts are probably more useful if you are going to
have a mixed Windows / Linux network, but I can't see why NFS mounts
wouldn't work.
