very short and basic question, i'm having trouble in a network's homework i'm having. This is the point i'm asked to implement:
- Configure SSH remote port forwarding in order to redirect the port 83 of pc1 to the port 8000 of s1.
To do it, i used a simple
s1:~# ssh -o StrictHostKeyChecking=no -NR 83:127.0.0.1:8000 email@example.com &
Where 10.0.1.2 is the ip of pc1, however every time i receive as return the warning:
Warning: Remote Port Forwarding failed for listen port 83
I have nothing running that's already using the 83, also if I try to locally (from pc1) try to listen on port 83 I can easly do it.
Note: i receive this error from all the privileged ports i try to bind.
