ssh -l salini 192.168.164.78

Но теперь я получаю это:

Проанализировав подробный вывод ssh-клиента, мы обнаружили, что: 

debug1: Connecting to 192.168.164.78 [192.168.164.78] port 22. debug1: Connection established.

Сервер был достигнут (нет проблем с сетью), и ваш ssh-клиент установит соединение по умолчанию через порт 22. 

debug1: Authenticating to 192.168.164.78:22 as 'salini'

ваш клиент попытается аутентифицировать вас как salini Он будет проходить через различные методы аутентификации, доступные (один за другим): 

debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password,keyboard-interactive

В конце он спроситвы за ваш пароль, так как он не мог аутентифицировать вас с помощью kerberos, publickey 

debug1: Next authentication method: keyboard-interactive Password: debug1: Authentication succeeded (keyboard-interactive). Authenticated to 192.168.164.78 ([192.168.164.78]:22).

Вы ввели пароль и теперь вы подключены к серверу

Теперь единственная проблемаэто то, что ваш $HOMEDIR исчез по некоторым причинам ... 

Could not chdir to home directory /home/salini: No such file or directory
