Read: In the name of thy Lord Who createth, Createth man from a clot. Read: And thy Lord is the Most Bounteous, Who teacheth by the pen, Teacheth man that which he knew not. Nay, but verily man is rebellious That he thinketh himself independent!. Lo! unto thy Lord is the return. (Sura Alalaq 96:8)

Using Redir command for redirecting ports

Redir is a very useful command line script that allows port redirection. The script listens on the given TCP port and forwards incoming connection to the given ip address and port

One use case for the Redir command is to setup SSH access for a container that is running inside a host system. For example if you are running LXC containers on a server and you want to be able to SSH to a container from outside the server, then you can use the redir command to redirect incoming connections on SSH port 22 or some other port to the SSH port of your container. The following redir command listens on all available ip addresses and port 1000. It redirects all incoming connections to port 22 on host 192.168.1.6. The '&' at the end of the command allows the command to run in the background


redir --laddr=0.0.0.0  --lport=1000 --caddr=192.168.1.6 --cport=22 &
