---Reply on mail from EDS about UDP port 137
My firewall has been alerting me to "possible port scans" on UPD for port 137. This seems to occur from a number of source addresses and domains on the internet, some resolve-able, some not. Does anyone know of a reason I should be concerned? John B.
That is WINS.. Windows DNS effectivly.. When I goto a windows nt based web server, I see that it tries to figure out who I am based on a querry via WINS.. I would warn you though, that WINS can give up information on the system (like the netbios name, which may not always equal the DNS name) so you may be wise to block that.. -- Bret McDanel http://www.rehost.com Realistic Technologies, Inc. 973-514-1144 These opinions are mine, and may not be the same as my employer
