sudo mount -t nfs -o rw santa:/home /net/santa/home
tries to grab the external (wild internet) interface IP of santa
and mount that. But, I block NFS to the wild with shorewall and
with my DSL modem.
sudo mount -t nfs -o rw 192.168.1.3:/home /net/santa/home
works just fine. That means that NFS is working. Autofs
might be working, but it's based on name lookup and that seems
suspicious to me.
My /etc/hosts entries for santa are thus:
192.168.1.3 santa.cosgrove.com santa
Ping works correctly:
PING santa.cosgrove.com (192.168.1.3) 56(84) bytes of data.
64 bytes from santa.cosgrove.com (192.168.1.3): icmp_seq=1 ttl=64 \
64 bytes from santa.cosgrove.com (192.168.1.3): icmp_seq=2 ttl=64 \
But, autofs is tries to do a DNS lookup of santa and comes up
with the external IP address. This DID NOT happen like this
until the auto update from 2010.1 to 2010.2. I searched the web
a bit for things like "/etc/hosts ignored". Someone there wrote
that /etc/nsswitch.conf needs to have "files" before DNS things
on the "hosts:" line. My file wasn't like that. The file had an
August 2010 date on it, so I didn't think that it would be part
of 2010.2. Even so, I tried swapping the putting "files" before
the DNS stuff, which had no effect.
I'm stuck again.
