You might have CA's InoculateIT. The AV product uses 42510 and 42509 and 42509 to communicate between the client and the admin. Check to see if your organization uses Computer Associates Anti-virus product.
-----Original Message----- From: Michael Krymson [mailto:[EMAIL PROTECTED]] Sent: Friday, June 07, 2002 6:51 PM To: [EMAIL PROTECTED] Subject: port 42510 I just wanted to ask if anyone knows what port 42510 would be doing open on a number of machines in my office's network. This includes almost all windows machines, 2000, 98, and NT... I have also see 41508 open as well, on the UDP side. Here is the entry: TCP Mike:42510 Mike:0 LISTENING UDP Mike:42508 *:* I have no idea what these are. I had a Windows 98 machine with nothing running, and this port and 139 (shares on the network) were the only ports open, and my searching on the net has revealed nothing. Anyone have any ideas? Much appreciated. ---------------------------------------- Sincerely, Michael Krymson [EMAIL PROTECTED]
