What is the Configuration Test Protocol, a thingie that uses ethernet type 09000 packets? Is it documented in any RFC? How useful is it? Is it a kind of ethernet ping? Many thanks. Mohamed PS: If it is a sort of Ethernet ping, I would suggest calling the program that uses it PENG (Packet EtherNet Groper)!

You'll find it documented in the DIX Ethernet spec, Version 2.0 (access info below). Basically it allows Ethernet controllers to reply to test packets, and to forward test packets on to another controller. The Test Protocol was dropped from the IEEE802.3 spec, and you will not find much support for it today. The major exception is DEC. DEC has included support for this protocol in many of their Ethernet controllers. Here's how to get a copy of the DIX spec: Ethernet Local Area Network Specification Version 2.0. November, 1982 Digital Equipment Corporation, Intel Corporation, Xerox Corporation, 103 pps. $32.00. DEC Part Number: AA-K759B-TK. Available from DEC-Direct by calling 800-344-4825.
