That was me. I haven't touched that code in a while but I should go take a look at it again. It used SHOW KNOWN CIRCUITS and SHOW ADJ NODES. Let me know when you're back online and I'll play with that some more. -brian On 4/3/2013 6:55 PM, Rob Jarratt wrote: A while ago there was discussion of a program or DCL script that was automating the creation of a map of HECnet. It stumbled when it came to my user mode router because it did not implement NICE. Well, I have been doing some work to rectify that. The work is far from complete, but under the right circumstances and with a fair wind you can get A5RTR to tell you the output of SHOW KNOWN CIRCUITS. Who was doing that work, and which commands needed to be supported for the program/script to work? Regards Rob NB A5RTR is not on HECnet at the moment because I have had a change of IP address and I am waiting for Johnny to tell his bridge to re-read its config.
