Well, I finally got something different. I upgraded to 2.5.2p2 and rebuilt everything. Very good, ./sshd -ddd - p 9xxx gets me this on the working machine:
debug1: Seeding random number generator debug1: sshd version OpenSSH_2.5.2p2 debug1: load_private_key_autodetect: type 0 RSA1 debug3: Bad RSA1 key file /etc/sshd/ssh_host_dsa_key. debug1: read SSH2 private key done: name dsa w/o comment success 1 debug1: load_private_key_autodetect: type 2 DSA socket: Address family not supported by protocol debug1: Bind to port 9399 on 0.0.0.0. Server listening on 0.0.0.0 port 9399. Generating 768 bit RSA key. RSA key generation complete. while it gets me this on the non-working machine: debug1: Seeding random number generator debug1: sshd version OpenSSH_2.5.2p2 debug1: load_private_key_autodetect: type 0 RSA1 debug3: Bad RSA1 key file /etc/sshd/ssh_host_rsa_key. debug1: read SSH2 private key done: name rsa w/o comment success 1 debug1: load_private_key_autodetect: type 1 RSA debug3: Bad RSA1 key file /etc/sshd/ssh_host_dsa_key. debug1: read SSH2 private key done: name dsa w/o comment success 1 debug1: load_private_key_autodetect: type 2 DSA socket: Address family not supported by protocol debug1: Bind to port 9020 on 0.0.0.0. Server listening on 0.0.0.0 port 9020. Generating 768 bit RSA key. RSA key generation complete. Any ideas would still be very welcome. Regards, Luigi Fabio - [EMAIL PROTECTED]
