linux - 无法在本地设置ssh

Question

我试过设置 ssh key 。具体遵循 bitbucket 和 ubuntu.com 上的说明。

sudo apt-get install openssh-client
sudo apt-get install openssh-server
ssh-keygen -t rsa

但是，当我尝试检查它是否安装正常时，可以进入。

ssh -v

我收到回复。

ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]
       [-D [bind_address:]port] [-E log_file] [-e escape_char]
       [-F configfile] [-I pkcs11] [-i identity_file]
       [-L [bind_address:]port:host:hostport] [-l login_name] [-m mac_spec]
       [-O ctl_cmd] [-o option] [-p port]
       [-Q cipher | cipher-auth | mac | kex | key]
       [-R [bind_address:]port:host:hostport] [-S ctl_path] [-W host:port]
       [-w local_tun[:remote_tun]] [user@]hostname [command]

但根据 Bitbucket，第一行应该是版本详细信息。

$ ssh -v 
OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011
usage: ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]
           [-D [bind_address:]port] [-e escape_char] [-F configfile] etc etc...

它还指出

If you have ssh installed, the terminal returns version information.

我在这里遗漏了什么吗？我在 Macbook 上运行 Ubuntu 14.04。

谢谢。

Answer 1

我认为:

ssh -v 是:

-v Verbose mode. Causes ssh to print debugging messages about its progress. This is helpful in debugging connection, authentica- tion, and configuration problems. Multiple -v options increase the verbosity. The maximum is 3.

和 ssh -V:

-V Display the version number and exit.
