建立ssh tunnel的命令

 

网上都是说 sudo ssh -L <local-port>:<VM IP address>:80 <your VM user>@<VM IP address> -N 

 但连上后都会出现错误

debug1: Connection to port 80 forwarding to 192.168.1.233 port 80 requested.

debug1: channel 2: new [direct-tcpip]

debug1: Connection to port 80 forwarding to 192.168.1.233 port 80 requested.

debug1: channel 3: new [direct-tcpip]

channel 2: open failed: connect failed: Connection timed out

channel 3: open failed: connect failed: Connection timed out

debug1: channel 2: free: direct-tcpip: listening port 80 for 192.168.1.233 port 80, connect from 127.0.0.1 port 47645, nchannels 4

debug1: channel 3: free: direct-tcpip: listening port 80 for 192.168.1.233 port 80, connect from 127.0.0.1 port 47646, nchannels 3

 

 最后想想把中间的ip换成自己的试一试  居然成功了。。   但这是为什么呢？不可能那么多人都错了啊。。。

 sudo ssh -L 80:127.0.0.1:80 root@192.168.1.233 -N  

 

 

 

另外，备忘一下  使用ssh代理服务器的命令 ssh -qTfnN -D 7070 username@58.xx.xxx.xxx 

端口转发： ssh -b 0.0.0.0 -fNR 59110:localhost:59155 localhost
