How to manage port 830 behind a firewall

Open basfrever opened this issue 6 years ago • 1 comments

Hi Michal,

My Libnetconf2 server is running on port 830. Only port 22 is visible behind the firewall and Openssh server runs on port 22(needed for other applications) . .Is it possible to route netconf requests on port 22 to port 830. .If not can we create an ssh session with openssh and pass the handle to Libnetconf2 server, for it to handle only netconf requests? Can you suggest any better way to accomplish this.

Thanks, pjm

Hi, to my knowledge, you cannot do it the former way. But, it should work the latter way, by configuring your SSH server to start an application in case the netconf subsystem is requested. But you will have to add support for this in your libnetconf2 server so that it somehow gets the input and output file descriptors created by the SSH server. You will then call nc_accept_inout() and it should work.

Regards, Michal
