OS X 下SSH 超时的问题

You need to change the ServerAliveInterval, as explained in ssh_config(5):

Sets a timeout interval in seconds after which if no data has been received from the server, ssh will send a message through the encrypted channel to request a response from the server. The default is 0, indicating that these messages will not be sent to the server.

For example, create ~/.ssh/config and add:

Host *
    ServerAliveInterval 120

This will apply to all connections. For a single connection, just use the -o option as explained in ssh(1):

ssh -o ServerAliveInterval=120 user@host
