I was given a device with embedded linux running a 2.6.x kernel. One thing that is weird with it is that when you telnet to it with root (yes, I know, don't ask), it does not prompt for a password, but instead lets you right in. If you log in with a different username, it does prompt for a password, and it has to be the correct one. This is running Busybox v1.14.3. I have been looking through config files, and using some google fu, but having a difficult time reproducing it on a separate system with the same version of Busybox running telnet. Does anyone know how I can recreate this?
