Issue with listing consoles with -u with port forwarding #88

Closed tse77 closed 1 year ago

tse77 commented 1 year ago

I have a setup where i'm running conserver on a raspberry pi which is connected to several devices over consoles. I have no issue running console client application on the raspberry pi and attaching to the different devices through conserver.

But when connecting to conserver from console over port forwarding I have an issue with listing consoles with "-u" argument.

Tested with the following versions of conserver: 8.2.6 8.2.1

The raspberry pi is connected to a server and is not accessible from the network it self. So I have enabled port forwarding on the server the following ports:

3109 (primaryport) 62000 (secondaryport)

When I connect with console from my laptop attaching to a console everything works fine:

command: console -D -M 10.2.83.240

Debug log from the session:

But when I want to list all available consoles with the following command:

console -D -M 10.2.83.240 -u

It fails!

When you compare the two different logs you can see from the log for the "-u" command it says incorrectly ip 198.18.121.10 and it can not reach that address of the raspberry pi since it is sitting behind the server.

But when attaching to the console (working example) you can see from the log that you don't get that incorrect IP so I wonder why.

Anyone have any ideas, could it be an issue with conserver/console?

Best regards Thomas

I worked it out with another setup so i'm closing this now.
