sshd fails to accept connections on HP-UX 11.00

[Ulrich Windl]

Hello,

we run OpenSSH_2.3.0p1 on HP-UX 11.00. Today I had a problem connecting 
to a machine via SSH. The connection seemed to hang. Syslog showed 
nothing, and no sshd processes were started, although I had two hanging 
connections (no output). I logged in via telnet and found one sshd 
(master) running in addition to a ssh-agent from a session that went 
away. That ssh-agent was owned by my user id. After killing the ssh-
agent, ssh login worked again.

I don't quite understand that: I thought ssh-agent is responsible for 
outgoing connections, but not incoming ones. In addition, how does the 
master sshd know about the existence of a ssh-agent?

Regards,
Ulrich
