![SSH exitOnForwardFailure=yes 不适用于本地转发(-L)](https://linux22.com/image/738554/SSH%20exitOnForwardFailure%3Dyes%20%E4%B8%8D%E9%80%82%E7%94%A8%E4%BA%8E%E6%9C%AC%E5%9C%B0%E8%BD%AC%E5%8F%91%EF%BC%88-L%EF%BC%89.png)
我想使用ExitOnForwardFailure
ssh 选项,但它似乎不起作用:
$ ssh -f -L 8080:localhost:22 -o ExitOnForwardFailure=yes [email protected] "sleep 60" ; sleep 3; ps xu|grep ssh
bind: Address already in use
halfgaar 780086 0.0 0.0 51432 728 ? Ss 12:32 0:00 ssh -f -L 8080:localhost:22 -o ExitOnForwardFailure=yes [email protected] sleep 60
另外如果我不 fork( -f
) 的话,我只会获得服务器的 shell:
halfgaar@<localmachine>: ~
$ ssh -L 8080:localhost:22 -o ExitOnForwardFailure=yes [email protected]
bind: Address already in use

当我尝试制作撤销隧道 (-R

答案1
看起来它的一部分使用了 ipv4,另一部分使用了 ipv6。当我使用 时-4
,我正确地得到了:
bind: Address already in use
channel_setup_fwd_listener_tcpip: cannot listen to port: 8080
Could not request local forwarding.
我也提交错误报告,因为它看起来确实像一个错误。
