修改 ssh server timeout 时间

在 /etc/ssh/sshd_config 中添加:

1
2
3
TCPKeepAlive yes
ClientAliveInterval 120
ClientAliveCountMax 720

The first one configures the server to send null packets to clients each 120 seconds and the second one configures the server to close the connection if the client has been inactive for 720 intervals that is 720*120 = 86400 seconds = 24 hours

或者在客户端的~/.ssh/config中添加配置:

1
2
3
Host *
ServerAliveInterval 60
ServerAliveCountMax 3 # 不设置表示不停重试

ssh client 在不同窗口之间共享 session

ControlMaster auto
ControlPersist 1000m
ControlPath ~/.ssh/master-%r@%h:%p
