I have installed OpenSSH on a RedHat 7.1. When I try to log on I get a 'connection closed' after I enter my password. What is wrong??? Here is the debug info: # /usr/sbin/sshd -ddd debug1: sshd version OpenSSH_3.5p1 debug1: private host key: #0 type 0 RSA1 debug3: Not a RSA1 key file /etc/ssh/ssh_host_rsa_key. debug1: read PEM private key done: type RSA debug1: private host key: #1 type 1 RSA debug3: Not a RSA1 key file /etc/ssh/ssh_host_dsa_key. debug1: read PEM private key done: type DSA debug1: private host key: #2 type 2 DSA socket: Address family not supported by protocol debug1: Bind to port 22 on 0.0.0.0.
