If your job involved servers, routers or anything attached to any network, I’m hundred percent sure this little tool is one of your best friend. Telnet is the name which is indispensable to any network admin or system admin. For the past few days, I have been struggling managing and configuring some of the network devices remotely. Without telnet, I think I will get blisters on my foot for walking up and down to the devices and to my room. Telnet helps me to access the devices on the network remotely. You can even use telnet across the ocean through the internet if you want to, that’s how indispensable telnet is.
