Since udp 137 is a well-known M$ port this could be normal, but it's worth checking. No one with a source IP that you don't know should be hitting that port anyway (to be frank, no one at all should be hitting that port). So check the target for vulnerability (file and print sharing, shares, non-renamed administrator account....) and see if the source is an attacker. --- Michael <snorter () gmx net> wrote:
Hello !!! I'm using Snort 1.9.0 and I am getting much alerts (portscans) like this: 11/07-05:38:45.031223 UDP src: 210.139.70.184 dst: xxx.yyy.zzz.223 sport: 1026 dport: 137 tgts: 8 ports: 8 event_id: 682 Sometimes there are more than hundred portscans a day. Every time the destination port is 137. Is this a real portscan or something else? Is it possible to ignore portscans to a specific port? Thanx for you help, Michael -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ NEU: Mit GMX ins Internet. Rund um die Uhr für 1 ct/ Min. surfen!
