Hi all, Tried to send this message earlier but didn't go through. Moved quite far and after installing SuSE here behind a M$ ISP I get the following messages all the time. May 1 16:17:36 sts kernel: Packet log: input DENY eth0 PROTO=17 192.168.0.101:137 192.168.0.255:137 L=78 S=0x00 I=16855 F=0x0000 T=128 (#3) May 1 16:18:18 sts kernel: martian source 0d00a8c0 for 6500a8c0, dev eth0 May 1 16:18:18 sts kernel: ll header: ff ff ff ff ff ff 00 e0 13 00 00 40 08 May 1 16:18:51 sts kernel: martian source 0a00a8c0 for 6500a8c0, dev eth0 May 1 16:18:51 sts kernel: ll header: ff ff ff ff ff ff 00 e0 13 00 00 37 08 Eth0 is the nic pointing to the internet ISP-M$. Port 137 seems to be related to netbios, thats OK because I don't want it, so firewall denies it. My questions are, why and what's the martian source ? How can I avoid it or is this related to M$-netbios or to the ISP M$-NT-netbios network. If so, any clue on charging M$ for using my diskspace, say one cent a log message line, due to sending incomprehensive, bugfull, martian code. TIA, Filip.
