|
||
> 运行、监控和重启SSH连接。
|
||
> 自动重新连接以保持端口转发隧道的畅通。接受所有SSH标志。

|
||
|
||
- 启动一个SSH会话,当[M]监控端口未返回数据时重启:
|
||
|
||
`autossh -M {{monitor_port}} "{{ssh_command}}"`
|
||
|
||
- 将一个[L]ocal端口转发到远程端口,在必要时重启:
|
||
|
||
`autossh -M {{monitor_port}} -L {{local_port}}:localhost:{{remote_port}} {{user}}@{{host}}`
|
||
|
||
- 在执行SSH之前将`autossh`分叉到后台,并且不打开远程shell:
|
||
|
||
`autossh -f -M {{monitor_port}} -N "{{ssh_command}}"`
|
||
|
||
- 在后台运行,没有监控端口,而是每10秒发送SSH保持活动数据包以检测故障:
|
||
|
||
`autossh -f -M 0 -N -o "ServerAliveInterval 10" -o "ServerAliveCountMax 3" "{{ssh_command}}"`
|
||
|
||
- 在后台运行,没有监控端口和远程shell,如果端口转发失败则退出:
|
||
|
||
`autossh -f -M 0 -N -o "ServerAliveInterval 10" -o "ServerAliveCountMax 3" -o ExitOnForwardFailure=yes -L {{local_port}}:localhost:{{remote_port}} {{user}}@{{host}}`
|
||
|
||
- 在后台运行,将`autossh`调试输出和SSH详细输出记录到文件:
|
||
|
||
`AUTOSSH_DEBUG=1 AUTOSSH_LOGFILE={{path/to/autossh_log_file.log}} autossh -f -M {{monitor_port}} -v -E {{path/to/ssh_log_file.log}} {{ssh_command}}` |
