THanks to everyone for their suggestions. I'll try to cover as many as I
1. Uhh...I didn't actually *try* to ftp to ftp.foo.com. That was an example.
2. The problem was not nsswitch.conf (I had hosts: dns files and do not
3. killing nscd made no noticeable difference.
4. Don;t use suns dns. I don't. THis was a fresh built BIND 4.9.3
5. more stuff that I had already tried...
Well, apparently everyone was right with respect to DNS (which is what I
thought, but I have so little experience with 2.5.1 that I thought there
might be a known bug...) It was clearly a DNS problem - recompiling
BIND and cleaning up my db files seems to have done the trick. Oh
well. Thanks again for all the help!!
ps. Here's a little something that I don;t even want to think about:
using IP addresses instead of hostnames was also slow and is now fast.
That sholdn;t have anything to do with DNS should it? Maybe reverse
lookups on the reverse end?
