Hello! In my firewall-log I can find several entries like this:
----8<----------- Oct 11 19:25:48 asterix kernel: Dropwall: IN=eth0 OUT= MAC=ff:ff:ff:ff:ff:ff:**:**:**:**:**:**:**:** SRC=***.***.***.*** DST=***.***.***.*** LEN=1456 TOS=0x00 PREC=0x00 TTL=110 ID=21266 PROTO=UDP SPT=17060 DPT=0 LEN=1436 ----8<----------- [Real IP's and MAC removed] I did some research and find out, that there is no port 0 (and I was shure that I have no service running on port 0 (it's even not possible)). So, what could this be? What could it be good for trying to connect to a not existing port? Is it a kind of scan? Somewhere on the internet I've read that in this way you can find out which OS is runnig. Thanks for your help!
