about two weeks ago, my server (running Potato) stopped accepting ssh, smtp and telnet requests. I would be able to connect on the respective ports, but would be disconnected shortly thereafter before receiving a login prompt. I've uninstalled and reinstalled all of the packages. The weird thing is, Apache and a mud I run on port 9000 are working just fine. My server is doing IPmasq, and any computer on the local network can get in just fine (ssh, telnet and smtp).
This happened quite suddenly, and I can't think of anything I may have done to cause this. Any thoughts?
