It would be a VERY good idea to block any samba traffic directed in from the Internet. From my firewall logs, the top three types of probes we get are: SunRPC (port 111) Samba (137,138) and PCanywhere (5632) Samba is a very chatty protocol which will propagate to the edge of the Internet if allowed. Let a broadcast get out and you can expect to receive a friendly reply... Be sure the other services are turned off if you do not specifically need them. > > > Is it also possible to Send/receive the "messenging service" of NT, > > respective the "Popups"? Do you mean the AOL messenger service? I think that comes in as POP traffic. Just 'allow' traffic on that port thru from the Internet. -- Richard Martin dmartin@origen.com OriGen Biomedical Tel: +1 512 474 7278 2525 Hartford Rd.
