兩台電腦沒兩台螢幕還挺不方便的, 用ssh連到另一台Linux用command line的缺點是一些X11 apps都沒辦法用, 不過好像ssh也不是只有文字可用
ssh -X my_host
用上面的方式就可以用X11 forwarding的模式連到Linux的那台, 這時候執行任何一個X11程式, 視窗就會在你的電腦顯示而非遠端那台Linux, 舉個例, 我從mac mini連到一台遠端的Linux執行banshee, 這就是mac mini上得到的結果(這screenshot有兩個視窗, 上頭是banshee run on X11, 下頭是terminal, 用ssh -X連到Linux並執行banshee):
"男人"(man)的說明是這樣寫的:
-X Enables X11 forwarding. This can also be specified on a per-host basis in a configuration file.
X11 forwarding should be enabled with caution. Users with the ability to bypass file permissions on the remote host (for the user's X authorization database) can access the local X11 display through the forwarded connection. An attacker may then be able to perform activities such as keystroke monitoring.
For this reason, X11 forwarding is subjected to X11 SECURITY extension restrictions by default. Please refer to the ssh -Y option and the ForwardX11Trusted directive in ssh_config(5) for more information.
