I looked in the archives, but the previous posts on this topic didn't say for sure whether these log entries are benign (or not). Anyone care to hazard a guess at the interpretation of the following entries? Note that the machine generating these messages has a fixed private IP address of 192.168.15.225, runs Samba server and connects to the Internet (via wireless) through a SonicWall Tele3 appliance (if all of that info is helpful). Thanks!
