Ok, so I got that file and put it in our server config path /opt/ftb/config , but I don't know how to have it only change the logging level of one mod (IndustrialCraft 2). I still want to see all other messages in console and server.log.0, as those are helpful when troubleshooting a crash.
I don't know all that much about setting up a server, and I was mainly given admin rank on our server for maintenance and restarts in the event of crashes.
So since FML doesn't generate a logging.properties file by default, I don't know what need to be in it to have everything log as it does without a logging.properties file, but only change the logging level of IC2 from INFO to SEVERE.
Can you guys help me with this, or even just pastebin the config you use? It would be much appriciated.
