Hi Biswas, There is more than that.Yahoo! Messenger works on ports: 20,23,25,80,119,5050. Based on the Yahoo server IPs, we may succeed in blocking connections. That would effect port 80 traffic too. I dont know whether there is a snort signrature to stop Yahoo!Messenger traffic.
Yahoo Server domain names: * scs.msg.yahoo.com * scsa.msg.yahoo.com * scsb.msg.yahoo.com * scsc.msg.yahoo.com For more info visit this link: http://help.yahoo.com/help/us/mesg/twin/twin-36.html -Ravi Biswas, Proneet wrote:

Does any one have a rule or know how to detect Yahoo instant messenger. I would like to block all instant messenger traffic in my network. Thanks, Mike Little Director of Network Services.
