Telnet Tool For Mac

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. Telnet is an incredibly useful diagnostic and debug tool. I use it at some point nearly every day diagnosing SMTP connection problems, accessing old Cisco switches / routers on my internal private/secure network, connecting to serial consoles across a local/private network and more.

PuTTY is a free implementation of SSH and Telnet for Windows and Unixplatforms, along with an xterm terminal emulator. It iswritten and maintained primarily bySimon Tatham.

Telnet On Mac Terminal

Of course, now few people use the telnet protocol, because there is SSH more powerful and secured tool, but still telnet sometimes could be necessary. Apple is so reckled about our security from that to exclude telnet from the list of basic Terminal commands on Mac.
