建立ssh tunnel的命令


 

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

 但連上后都會出現錯誤

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
 

 最后想想把中間的ip換成自己的試一試  居然成功了。。   但這是為什么呢?不可能那么多人都錯了啊。。。

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

 

 

 

另外,備忘一下  使用ssh代理服務器的命令 ssh -qTfnN -D 7070 username@58.xx.xxx.xxx 

端口轉發: ssh -b 0.0.0.0 -fNR 59110:localhost:59155 localhost
