sshd 3.1 dumps core when client connects -- Solaris 9 gcc 3.1
Team - I'm running Solaris 9 and gcc 3.1 on a Blade 1000, named jefferson. I built OpenSSH_3.3. I can use the client to connect out, but cannot use the client to connect to localhost (nor can I use a Linux box with OpenSSH_3.2.3 to connect to it). I *can* use F-Secure 3.0.0 on a Windoze box to get into it. I've tried configurations both with and without privsep enabled but get the same results. This is the trace when connecting using the OpenSSH client: jefferson# /usr/local/sbin/sshd -d -d -d debug1: sshd version OpenSSH_3.3 debug3: Not a RSA1 key file /usr/local/etc/ssh_host_rsa_key. debug1: read PEM private key done: type RSA debug1: private host key: #0 type 1 RSA debug3: Not a RSA1 key file /usr/local/etc/ssh_host_dsa_key. debug1: read PEM private key done: type DSA debug1: private host key: #1 type 2 DSA debug1: Bind to port 22 on ::.
