Details
With Tera Term 4.73 I can't connect to an SSH server that sends extra debug messages in the SSH2 protocol. In my case the server is a firewall box that relays the connection and inserts some additional debug messages.
Tera Term displays an error message box saying "Unexpected SSH2 message(4) on current stage(4). DEBUG message from server: Original server fingerprint for ..." and then disconnects :-(
Here is the debug output when connecting with OpenSSH "ssh -v" client (I've highlighted the extra debug message):
debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to 192.168.61.60 [192.168.61.60] port 22000. debug1: Connection established. debug1: permanently_set_uid: 0/0 debug1: identity file /root/.ssh/id_rsa type -1 debug1: identity file /root/.ssh/id_rsa-cert type -1 debug1: identity file /root/.ssh/id_dsa type -1 debug1: identity file /root/.ssh/id_dsa-cert type -1 debug1: identity file /root/.ssh/id_ecdsa type -1 debug1: identity file /root/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.0-beta debug1: match: OpenSSH_6.0-beta pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.8p1 Debian-7ubuntu1 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: DSA 6f:c3:69:7e:2b:3a:85:f3:3d:ed:09:74:4e:f4:21:66 debug1: Host '[192.168.61.60]:22000' is known and matches the DSA host key. debug1: Found key in /root/.ssh/known_hosts:63 debug1: ssh_dss_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent ***************** debug1: Remote: Original server fingerprint for [192.168.60.13]:22000: RSA 02:82:ab:52:13:70:4f:16:1f:30:ad:37:61:3e:50:ee ***************** debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Next authentication method: publickey [...]
Can Tera Term just ignore unknown debug messages?
