4/28 の日記 (同 3/23) に、ssh -Y 等のことに関連して、

• ssh 元 (client) の /etc/ssh/ssh_config に次のように書いておいて

  47  # If you use xorg from pkgsrc then uncomment the following line.
  48      XAuthLocation /usr/pkg/bin/xauth
  

• ssh -Y hostname を使っている

と書いた。ここから二段階進む話。 これらは ~/.ssh/config に設定が可能で、例えば、

ForwardX11Trusted yes
ForwardX11 yes
XAuthLocation /usr/pkg/bin/xauth

と書いておけば、/etc/ssh/ssh_config は変更する必要がないし、 -Y も付ける必要がなく、単に

ssh hostname

で行けることが分った。 (server 側の /etc/ssh/sshd_config には次の行が必要)

X11Forwarding yes

ただし、いつもこのように ~/.ssh/config に書いておくのが安全かどうかは良く考えていない。
この ~/.ssh/config の書き方としては man sshd_config が参考になるけれど、 Match 文は書けないようだ。

If we have to type return for following prompt,

It might be missing just colon(:), which gives empty password.
