Hi,
I've setup a small LAN of two desktops running CentOS 5 in a medical office. Both are connected to the Internet via a small modem/router.
Recently I played around with FreeNX on my own desktop, and I'd like to install it on these two computers. On my PC, I just redirected port 22 in the router, so SSH (and thus FreeNX) requests from the outside get redirected to my desktop PC. (And yes, I have a strong password :oD)
I'd like to handle the two PCs from the medical office remotely with FreeNX. I figured that the best way to distinguish them would be to assign a different port for SSH to each of them, and then redirect each of the ports respectively.
- How do I choose different port numbers for SSH ? Any conventions or
caveats for this ?
- How do I configure these different ports ? By that, I mean : how do I
tell SSH to use them instead of port 22 ?
You don't really need to change the ports on the hosts. Just configure the router to accept different ports on the internet side and redirect to port 22 at the different IP addresses on the inside. Then you only have to change the client settings for access from outside. I'd move both of them away from port 22 on the outside, though - you'll avoid a lot of password guessing attempts that will happen otherwise.
