OpenSSH SSH クライアント (リモート ログイン プログラム)

ssh user@host

パラメータ

  • -p port
  • -i identity_file

man

  •      -T      Disable pseudo-terminal allocation.
         -v      Verbose mode.  Causes ssh to print debugging messages about its progress.  This is helpful in debugging connection,
                 authentication, and configuration problems.  Multiple -v options increase the verbosity.  The maximum is 3.
         -X      Enables X11 forwarding.  This can also be specified on a per-host basis in a configuration file.
