OpenSSH : SSH Port Forwarding

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

[cent@dlp ~]$ ssh -L 10.0.0.30:8081:10.0.0.51:80 cent@node01.srv.world

cent@node01.srv.world's password:  

[cent@node01 ~]$

# confirm

[cent@node01 ~]$ ssh dlp.srv.world "ss -napt | grep 8081"

cent@dlp.srv.world's password:

LISTEN   0         128               10.0.0.30:8081             0.0.0.0:*        users:(("ssh",pid=1951,fd=5))

# 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.

Char values are surrounded by single quotes boolean - stores values with two states: true or false [2].
