I posted a Cisco 2501 for auction on Ebay on a Friday. To make my product stand out from the intense competition I decided to do something different. I decided to connect the router to the internet using my high speed cable modem. I enabled telnet and posted the access information on Ebay with the tile “TRY FRIST BEFORE BUYING – CISCO 2501 ROUTER�. Now an interested buyer could telnet into the router and issue the command allowed in user mode. Obviously I did not give out the privilege mode password.
Some the useful commands allowed in user mode are, show version, show flash, show memory etc. The show version command provides the most useful information to the buyer, below is the result of show version on my router.
