OpenSSH : SSH Port Forwarding2023/02/20 |
|
It's possible to forward a port to another port with SSH port forwarding.
|
|
| [1] | For example, set SSH Port Forwarding that requests to port [8081] on [dlp.srv.world (10.0.0.30)] are forwarded to port [80] on [node01.srv.world (10.0.0.51)]. |
|
# SSH login from source host to target host [alma@dlp ~]$ ssh -L 10.0.0.30:8081:10.0.0.51:80 alma@node01.srv.world alma@node01.srv.world's password: [alma@node01 ~]$ # confirm state [alma@node01 ~]$ ssh dlp.srv.world "ss -napt | grep 8081"
alma@dlp.srv.world's password:
LISTEN 0 128 10.0.0.30:8081 0.0.0.0:* users:(("ssh",pid=3311,fd=4))
# listen on 8081
# keep this login session |
| [2] | Verify to access to a port on source Host you set from any client Host, then target port on target Host replies. |
