Secure SHell

SSH 打通：

ssh-keygen -t rsa

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

SSH代理：

ssh -f -N <user name>@<ip or domain> -D <port>

ssh -i

ssh -i id_rsa  // private key, the pub key >> authorized_keys [id_rsa的机器需要和目标机打通]

mac 下自动打通工具：

~/.ssh/config

ServerAliveInterval 300
ServerAliveCountMax 36

service sshd restart
