Here is what I got, it hangs on "debug2: we sent a keyboard-interactive packet, wait for reply" for about 10 seconds. ssh -vvv root@192.168.0.3 OpenSSH_4.3p2 Debian-8ubuntu1, OpenSSL 0.9.8c 05 Sep 2006 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 192.168.0.3 [192.168.0.3] port 22. debug1: Connection established. debug1: identity file /home/andy/.ssh/identity type -1 debug1: identity file /home/andy/.ssh/id_rsa type -1 debug1: identity file /home/andy/.ssh/id_dsa type -1 debug1: Remote protocol version 1.99, remote software version OpenSSH_3.9p1 debug1: match: OpenSSH_3.9p1 pat OpenSSH_3.* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.3p2 Debian-8ubuntu1 debug2: fd 3 setting O_NONBLOCK debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug2: kex_parse_kexinit: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 debug2: kex_parse_kexinit: ssh-rsa,ssh-dss debug2: kex_parse_kexinit: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour128,arcfour256,arcfour,aes192-cbc,aes256-cbc,
