Hello

I run Kerio Connect 8 RC 2 on Ubuntu 12.04 server x86_64. I have the security tool called Tiger installed that reports suspicious changes. Today at 2 pm CET, this was reported:

--WARN-- [lin002i] The process `mailserver' is listening on socket 55178 (UDP) on every interface.

The alert was cancelled when the check later ran at 6 pm CET. I have looked through all logs to see if this has ever happened before. There are no recorded changes in ANY listening ports for Kerio Connect's mailserver process for the last months. (I haven't gone through the previous logs yet)

There have been a number of serious attacks on my system before, so I suspect this may be the result of a hacker trying to subvert Kerio Connect. Btw, Tiger gets the data by running lsof -i.

Could there be any other reason for this to happen?

Note: this port was not open when Tiger scanned at 10 am the same day. Kerio Connect has not been restarted and its logs show no significant errors.
