I have a Windows 2000 Active Directory. I just added a Linux client. The
linux client is receiving DHCP from my domain controller. I've added an entry
for my linux client in Windows 2000 DNS so now all my Windows machines can
ping the linux machine by its hostname.

I set /etc/resolv.conf on the linux machine to use the correct domain and
nameserver. I also set /etc/host.conf: order bind, hosts and
/etc/nsswitch.conf: hosts: dns files

This is the wierd part. From the linux machine I can ping stuff on the
internet (like Google) however, I can't ping anything inside my local network
by hostname. I even tried pinging using the fully qualified domain name but
still no luck.

Now it gets really wierd. If I use nslookup on the linux machine I can query
query local hostnames and it works fine. So why does that work but ping
doesn't?

Okay, after lots of research I fixed my own problem. The problem was due to
the fact that I'm using the .local suffix in my Windows domain. Aparently
SUSE Linux doesn't like this or rather libresolv doesn't like this. Programs
like ping use libresolv but other programs like nslookup don't. Here's what I
did at my linux machine:

cd /lib
cp libresolv.so.2 libresolv.so.2-orig
rm libresolv.so.2
cp libresolv.so.2-orig libresolv.so.2
perl -pi -e 's/local/lozal/g' libresolv.so.2
shutdown -r 0

I have no idea what that does or why it works but it did. I can now ping
all the machines in my local network by hostname.

I don't play much with Linux, but I can comment on one of my customers using
numerous Mac OSx systems in their environment, which is BSD based and has
the same problem as Linux in this respect because Mac, for it's Rendezvous
name, uses .local. We overcame that by jumping thru a few hoops early on.

Glad you figured it out.

That is really interesting. I use Redhat (Fedora) for numerous things in our
operation and have never had a problem with .local as the DNS suffix. In
fact it's been my tradition to use .local for Windows AD setups for years.
I'll definitely file both of these posts away for future reference.

For the OP:

I'm not a perl programmer, but one could assume that after making a backup
of your original libresolv.so.2 file it replaces references to "local" with
"lozal".

I can tell you it sure was a learning experience with Macs and Rendezvous!
