  1. .ssh/config as follows:

    host log
            hostname 23.251.96.137

            ServerAliveInterval 30
            GSSAPIAuthentication no
            ForwardAgent yes
            TCPKeepAlive no

    the debug info for the bad situation:

  2. i first login to the server without password, after the network broken, i login to the server again in the same panel in tmux. it ask for a password:

    10:28:06#walkerxk@ubuntu1/~> ssh log date
    Enter passphrase for key '/home/walkerxk/.ssh/id_rsa_2':
    Wed Nov  7 02:28:15 UTC 2018
    10:28:15#walkerxk@ubuntu1/~>

    i open another panel  in tmux and login to the server, i don't ask for a password

    10:28:09#walkerxk@ubuntu1/~> ssh log date
    Wed Nov  7 02:28:13 UTC 2018
    10:28:14#walkerxk@ubuntu1/~>
  3. script as follows:

    #!/bin/bash
    eval `keychain --noask --eval id_rsa_2`
    ssh -vvv 192.254.80.9 date

    i run it manually, it works:

    ssh 192.254.80.9 date
