Your IP at the time was this: $ host cmb8-158.dial-up.arnes.si cmb8-158.dial-up.arnes.si has address 194.249.38.158 DNS suggests it's a dialup node, but it's on your eth0 interface?

This packets are logged on my external interface. Im on cable, and IP address starts with 82.xxx.xxx.xxx. I have nothing to do with this packets. They are just logged. >> My ip number is totaly diferent from >> 194.249.38.255..

If > it's Ethernet, 194.249.38.255 might be the broadcast address. Yes, its on external Ethernet card. If 194.249.38.255 is broadcast, why then they end on my inetcard, which is on completly different network, ip. > >> Wed Jan 14 12:33:27 2004; UDP; eth0; 140 bytes; from >> cmb8-158.dial-up.arnes.si:1322 to 194.249.38.255:39213 Wed Jan 14 12:33:28 >> 2004; UDP; eth0; 852 bytes; from cmb8-158.dial-up.arnes.si:1323 to >> 194.249.38.255:39213 Wed Jan 14 12:33:29 2004; UDP; eth0; 296 bytes; from >> cmb8-158.dial-up.arnes.si:1324 to 194.249.38.255:39213 Wed Jan 14 12:33:29 > > The origin ports seem to be incrementing, whilst the destination port is > fixed. Were you doing some kind of port scan? Is this kind of DoS or something.. constantly flooding my external interface with UDP packages... Definetly they all end on 39213 port, and source port is incrementing.., BUT source addres is on different network than my addres and destination addres is also on different network... so why they end on my interface??? This is going on for days... making me little nervous... > > Oh well, enough of this for today.
