TraceMAC is a command-line Layer 2 traceroute for Cisco switches
TraceMAC is a Windows/Linux command-line tool that allows you to trace a specific MAC address thru Cisco switches.
It works by connecting to a switch using SSH, SNMP, Telnet, HTTP or HTTPS and do some "show commands" and later process the output, this will happen recursively until it finds the switch where that MAC address (PC/Printer/Etc) is directly connected.
chainssh is a shell script to smplify the ssh login via multiple sshgateways/firewallgateaways. e.g. connect from homehost via sshgateway to a clusternode with one command.
