Bug#35089: Slink's libc6 breaks linked internet apps (ftp, telnet, etc)
Package: libc6
Version: libc6_2.0.7.19981211-6
[Note: A similar bug report is found at Bug#:34263]
After upgrading from hamm to slink, the new libc6 in Slinks distribution,
has broken several internet programs. It errors about these programs,
which are linked to the libc6 library, not resolving names properly. I
have installed several Slink systems from scratch and have no problems,
however my only upgraded slink system (from hamm) ended with these programs
(ssh, telnet, ftp, smail, etc.) not functional.

and mysystem.louisville.edu as my Debain Linux system which is having trouble.

...I can resolve using nslookup. I run a caching DNS and my resolv.conf
has two entries for nameserver that are the DNS servers for campus. My box
does not appear in resolv.conf, but it still searches there.
Now if I downgrade libc6 to hamm's version... all problems, that I can
tell, are corrected:

My original NCFTP did not suffer from this problem since my version of
NCFTP is linked to libc5. I have since upgraded the package and it is now
linked to libc6.
A separate problem, but could be relevant here is that my BIND seems to be
handling requests, but i am not sure how or why it is doing it. As I said,
my local IP or 127.0.01 do NOT appear in /etc/resolv.conf. If I stop bind
services, I cannot resolve names in any manor. This behavior was there
even with HAMM so I don't see it as a part of this problem, but it could
help out.
So I am not using Hamm's Libc6 (2.0.7t-1) until I can get this other
problem resolved.
This problem occurred in Kernel versions 2.2.4 and 2.0.36.
