本文介绍了一种在Ubuntu 13.10/12.10中通过修改/etc/ssh/ssh_config文件来解决SSH仅能在Putty上工作而不能在终端上工作的具体步骤。通过对配置文件进行必要的修改并添加特定的主机密钥算法，可以成功地让SSH客户端与GitHub服务器建立稳定连接。

The solution was found here: SSH works in putty but not terminal

in Ubuntu 13.10/12.10, login and gain sudo access.

Edit /etc/ssh/ssh_config, uncomment the following lines

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc
GSSAPIAuthentication yes
GSSAPIDelegateCredentials no
MACs hmac-md5,hmac-sha1,umac-64@openssh.com,hmac-ripemd160

Add the following line

HostKeyAlgorithms ssh-rsa,ssh-dss

You should end up with your /etc/ssh/ssh_config file looking like this

Host *
Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc
MACs hmac-md5,hmac-sha1,umac-64@openssh.com,hmac-ripemd160
SendEnv LANG LC_*
HashKnownHosts yes
GSSAPIAuthentication yes
GSSAPIDelegateCredentials no
HostKeyAlgorithms ssh-rsa,ssh-dss

Now run ssh -T -v git@github.com and it will ask you to add the server to your known hosts file. Hit yes, and then it should welcome you to the server.
