nice packet tracer for Cisco ios in gns
Did you develop such thing? Are you looking for someone to do it for you? Or maybe you just want to sniff traffic from your dynamips topology using built-in features of GNS?
If you answered YES to the last question - > Capture functionality in dynamips/GNS + sniffer eg. Wireshark
i have installed wireshark
now how to linkto GNS 3
what are the steps to config
Have you tried to check it in documentation for GNS (GUI) or dynamip/dynagen (CLI)? No offence, but it really helps.
