Peg DHCP
Peg DHCP a method of assigning the correct network configuration to the individual devices in a Local Area Network (LAN), similar to DHCP , but with the help of clothespins ( pegs ).
history
Peg DHCP is described in RFC 2322 published April 1, 1998 by the Internet Engineering Task Force for an April Fool's joke . Nevertheless, the method is actually used successfully in practice.
On the occasion of the Hacking In Progress 1997 event , a robust solution was sought to avoid having identical IP addresses for multiple participants. DHCP using a server running on Unix was discarded because unexpected problems with a software solution were considered likely.
Procedure
Each IP address to be assigned is written on a clothespin that is kept ready for collection. Parameters that are valid for the entire network, such as the network mask and the IP address of the router, are written on paper and posted or distributed as a copy. Each parameter is set separately on each individual device and the clothespin is then attached to the respective network cable.
Clotheslines are provided to hold IP addresses and clothes hangers are used to assign subnets . The specification also includes how the clothespins and papers are attached to carrier pigeons in order to use the method as Internet Protocol over Avian Carriers .
safety
Even at the event to which the process goes back, it did not guarantee the security of the network. One participant had assigned the IP address of the router to his computer and thereby blocked access to the Internet . This can happen through a simple mix-up, but with the appropriate equipment it can also be used for a man-in-the-middle attack .
If used well, mix-ups and typing errors when setting up each individual computer must be avoided as well as spelling mistakes when labeling the clothespins.
Applications
The process was also used in the follow-up events to Hacking in Progress . At the Chaos Communication Camps and Chaos Communication Congresses , it is regularly offered alongside regular DHCP, as many visitors see it as a kind of tradition.
Also at other events and technology conferences, such as B. the System Administration and Network Engineering (SANE) conference, the Linuxdays or the LinuxTag Peg DHCP was or is used.
