Can not authenticate to server

[tomaskir]

Greetings,

Getting login failure against an Araknis switch. I can login to this device without an issue with Putty with the same credentials.

This same code works fine with other devices (Cisco, HP, etc.).

Code used:

final SSHClient sshClient = new SSHClient(new DefaultConfig());
sshClient.addHostKeyVerifier(new PromiscuousVerifier());

try {
    sshClient.setConnectTimeout(timeout);
    sshClient.connect(address, port);

    sshClient.authPassword(user, pass);
} catch ...

Log:

Any idea what could be wrong or how to further debug this?

Thanks!

As there is an USERAUTH_FAILURE, I would recommend revisiting the credentials. They might've been mistyped.

Else please provide trace logging.

Sadly I no longer have access to the switch this issue was present on.

Credentials were correct, I checked multiple times.
