Security threats -- Firestarter?

Tags:

I installed Firestarter in Debian 4 and I keep getting the following messages over and over again:

Time:Dec 30 00:27:10 Direction: Inbound In:eth0 Out: Port:515 Source:192.168.0.100 Destination:192.168.0.101 Length:48 TOS:0x00 Protocol:TCP Service:Printer

Should I worry about this? Have anyone here seeing the same messages? Don't know if this will help, but I have a DLink wireless router. My Debian system is plugped to it with a cable and I have an XP system in the house connected wireless. Thanks!

This is portscan from your lan, just check which machine the ip belongs to, if it's one legitimate there's probably something wrong with the machine network settings. If the ip doesn't belong to you lan machines, then you have naughty neighbors !
