Directing port traffic from interface to localhost

jpresto · 02-03-2015, 10:09 PM

I have a mongodb process which I'm unable to change the config on and it's bound to localhost only. I'd like to connect to it from another system.

I may have exhausted my options for trying to change the config file - is there any way to route tcp a single port's traffic from eth1 over to localhost?

Thanks in advance - Joe

Might try ssh forwarding. You will need ssh access with TCPForwarding set to yes for this to work.

Code:

ssh -R remoteip:remoteport:localip:localport hostname

This will forward all traffic going to the remote port to the local port you specifiy.

Do you own the system? Generally, subverting security is not a way to get on people's good side.
Just saying

My systems. Background is this is a unifi controller and it launches mongodb without any way to change the bind address. I want it on an IP so I can connect to it via an ODBC driver on a windows box.

I'd rather avoid using SSH on the remote side.. and forgive linux ignorance, but perhaps iptables??

You could likely port forward using iptables so that external devices can connect

But if the process is localhost bound, then a connection by a external ip will not work. Since you can't seem to change that behavior, the only way I know would be to "trick" it, using ssh.
If windows is involved though, I can't say whether it would work or not.

However, someone else may have an idea.
