Hello Freebsd Guru's, In my day to day matters I have noticed several port 137 packets getting nixed by my firewall. In looking at some tcpdump output I have noticed the following packets originating here and destined for places on the Internet and some places on the Internet destined for my internal network. I am curious what would cause this and how this can be disabled?? IS there a security issue out there related to this type of traffic?? I have attached my tcpdump output below. If anyone can pass on any info related to these issues to me I would be appreciative. If possible email me back directly. Thanks very much for your info/help Ryan TCPDUMP OUTPUT FOR 3 PACKETS: 15:50:08.319069 X.X.X.X.netbios-ns > X.X.X.X.netbios-ns: udp 50 (ttl 32, id 9475) 15:50:10.059069 X.X.X.X.netbios-ns > X.X.X.X.netbios-ns: udp 50 (ttl 32, id 10499) 15:50:11.569069 X.X.X.X.netbios-ns > X.X.X.X.netbios-ns: udp 50 (ttl 32, id 10755) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
