We are, network engineers, have many *nix tools at our disposal: exaBGP, nmap, tcpdump, to name a few. And with UNetlab its very easy to run a linux system inside a topology (not to mention that you could use cloud
pnet interface to bridge unetlab topology with the real world). By default UNetLab’s linux template opts to VNC access, which is cool if you have a GUI, but for a networker – CLI is the only love. In this post I will share with you a method to get telnet access to a linux image inside the UNetLab.
