I'm using ssh 3.5p1-3.  I tried reverting to 3.4p1, but still had the same
issue.  I'm using dante-client 1.1.13-1.  This also exists on ia64, fwiw.

So, as I see it, this could just as likely be a bug in either ssh,
libc6 & libc6.1, or dante-client, so please reassign as necessary.

I've verified that this problem exists on 4 different i386 boxes running sid.
However, there is a fifth i386 box running the same versions of these packages
that works just fine.  woody machines pointing at the same dns/socks servers
work fine.

On one of the 4 that show this problem, adding an entry for the target host to
/etc/hosts fixed the problem. (I couldn't check the other 3).
Removing the entry broke it again.  This, and the fact that I first noticed
the problem after a recent libc6 upgrade, is why I chose to file the bug
against libc6.

## my nsswitch.conf is pristine
dannf@hazel:~$ grep ^hosts  /etc/nsswitch.conf
hosts:          files dns

I tried rebuilding both dante-client and ssh against the headers on the
system, but didn't see a change.

thanks

It's a bug in Dante.  I diagnosed it for Bdale a couple of weeks ago,
so I don't exactly remember the details; I believe it's calling
__res_init at a time when it shouldn't and it used to work by luck.
