problems logging in from 1.2.2 client to 1.2.1pre24 server

[Marc Haber]

Hi!

On my personal workstation, I have installed openssh 1.2.2. I have two
server machines, one (A) running a self-compiled openssh 1.2.1pre24,
and a different one (B) running an openssh1.2.1pre24 compiled by
someone else.

While I can perfectly log in to A, logging in to B fails:
|mh at leona[32/532]:~$ ssh haber at b
|ssh_exchange_identification: read: Success
|mh at leona[33/533]:~$

So, I started a debugging sshd on B and tried to log in to B:
|mh at leona[34/534]:~$ ssh -p 10022 haber at b
|ssh_exchange_identification: read: Success
|mh at leona[35/535]:~$

|haber at b:~ $ /usr/sbin/sshd -d -p 10022 -h test_host_key
|debug: sshd version OpenSSH-1.2.1
|Server listening on port 10022.
|Generating 768 bit RSA key.
|RSA key generation complete.
|debug: Server will not fork when running in debugging mode.
|haber at b:~ $

What's going on here? Any ideas?

Greetings
Marc
