Muhammad, If I'm understanding you correctly, you have enabled SSH v2 and you're wondering why you're still able to telnet to the device after having removed the configuration from the VTYs. You need that configuration on your VTYs, but you also need to specify the transport layer protocols allowed. Try this to deny everything except ssh; line vty 0 4 transport input telnet ssh transport output telnet ssh line vty 5 15 transport input telnet ssh transport output telnet ssh Hope this helps. //rr Your network connectivity issues are most likely caused by TIME-WAIT state assassination due to an inadequate ephemeral port selection algorithm. -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of Muhammad Hafiz Rafek Sent: Monday, January 24, 2011 5:00 PM To: Mohamed Farid Cc: security-basics () securityfocus com Subject: Re: Cisco Telnet Service Yes..
