一、生成公钥key
$ ssh-keygen -t rsa -C [email protected]
一路回车，直到生成 id_rsa, id_rsa.pub
二、http://git.oschina.net/profile/sshkeys添加公钥
三、安装connect-proxy，也可以使用linux自带nc命令
rpm文件下载
http://rpm.pbone.net/index.php3?stat=3&search=connect-proxy&srodzaj=3
$ sudo rpm -ivh connect-proxy-1.93-2.el6.i686.rpm
四、添加~/.ssh/config
$ vim ~/.ssh/config (没有则新建文件),添加
Host git.oschina.net *.oschina.net
ProxyCommand connect-proxy -H 192.168.60.34:18608 %h %p 或
#ProxyCommand /usr/bin/nc -X connect -x 192.168.60.34:18608 %h %p
IdentityFile ~/.ssh/id_rsa
User [email protected]
说明：ProxyCommand可以用linux自带/usr/bin/nc命令，参考man 5 ssh_config
ProxyCommand /usr/bin/nc -X connect -x 192.168.60.34:18608 %h %p # Redhat7.3不可行
$ chmod 600 /home/caiwang213/.ssh/config，不然会提示：
[caiwang213@caiwang213 ~]$ ssh -v -T [email protected]
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013
Bad owner or permissions on /home/caiwang213/.ssh/config
五、验证
$ ssh -v -T [email protected] 提示：
[caiwang213@caiwang213 ~]$ ssh -v -T [email protected]
