Resolves an issue with automatic disconnection of SSH link server timeouts

For security, SSH's default connection time-out is short; it's often just a matter of being disconnected; You can actually change the time-out.

Sample environment:

Server: centos6.5

1:[[email protected]/]cp/etc/ssh/sshd_config /etc/ssh/sshd_config.bak //Develop a backup configuration item Good habit

2:[[email protected]/]vim/etc/ssh/sshd_config

Delete the comment # number 110 lines Clientaliveinterval 0 and change to Clientaliveinterval 5

Delete 111 lines of Lientalivecountmax 3 before the comment # number and change to Clientalivecountmax 180

3:[[email protected]/]service sshd reload;

[Email protected]/]/etc/init.d/sshd restart;

Restart the SSH service;
