In light of April fools day, here is a small list of a pranks instead of an elaborate story. Feel free to add your own pranks in the comments.

 

Disclaimer: Pranks can get your fired. I am not responsible for your lack of judgment. If the target is not a person that would enjoy a good prank….leave them alone. If your manager does not enjoy a good prank … leave everyone alone and just think about how funny it would be.

 



 

  1. Clear tape on a patch cable.

    2.  

    • Remove the patch cable from the target’s PC.
    • Apply clear tape to cover the bottom of the RJ45 connector.
    • Re-connect the patch cable.

     

  2. Set the hostname on a router / switch to ‘rommon’

    3.  

    • Login to a router (lab environment)
    • Change the hostname to rommon
      config t
      hostname rommon
    • Casually ask the target to do something on the router.

      •  

    It is a bit confusing to ssh into a router and be greeted by the ‘rommon>’ prompt

     

  3. Set the exec timeout on a vty port to 1 – 10 seconds.

     

    • line vty 0 4
      exec-timeout 0 1

     

    This will allow the target time to login to the router or switch but not really do anything before he is kicked out. Its frustrating.

    4.  

  4. Turn on the MWI light.

     

    If your office is using Cisco Call Manager / Call Manager Express, you can dial the ‘MWI On’ extension from someone’s phone while they are away…provided you know the ‘MWI On’ extension and the MWI Extensions are not protected with Calling Search spaces and partitions.

    5.  

  5. Send an embarassing email, twitter/ facebook update from an unlocked PC.

     

    No explanation necessary. WARNING: This one really could get you fired. At one time this was a lot of fun at my office. Now, it can lead to termination.

    6.  

  6. Configure a router to log to a server that is alive but not running a syslog service. Set the “logging monitor 3″ and “logging trap 7″ Then use the ‘debug ip icmp’ command on the router in exec mode.

     

    This little trick will consume a lot of bandwidth. I found this by accident. It wasn’t a joke. It will start with a log sent from the router to the server. The server will respond with a ‘service not available’ (or something similar) ICMP message. The router will attempt to log the ICMP debug to the server, which will send another ICMP message….and on and on….
