This is definitely not true across the board (I use it all the time, for example), so I'm downgrading this bug.
The weird thing is that I don't think this is directly due to the ssh pacakge. I think I was using it for a few weeks before this happened, but I'm not absolutely sure. Anyway, I upgraded a large number of packages recently, and then ssh didn't work. It is probably one of glibc, libz or pam which is the root cause of this bug... but I can't work out which one of those it is. No other program shows a problem, which is why I originally sent the bug report here. :-/

Is there any way you can set up an environment that I can attempt to connect to and check? The host key check happens before authentication, so I wouldn't need an account.
Unfortunately not. The machine with the problem lies beyond a firewall which isn't in my control. All incoming ports are filtered so it isn't reachable from the outside. :-/
However, I have a non-debian linux machine inside the firewall... and sshing from there to the broken box yields:
hash mismatch key_verify failed for server_host_keyIt isn't the network itself which is the problem, since I can ssh from the non-debian machine to the Alphas running Tru64 without any problem.
Also, what architecture are you using?
i386, handrolled kernel 2.6.1I've be fiddling with the source to see if I can find out what is going on, but no luck so far. If you want me to apply any debug patches etc, I'll be glad to help.
