Good to know. Being a unix guy I probably would have assumed case sensitivity. :)
What is regex??
Regular Expressions. A pain in the ass to learn but totally worth it.
Circuit names for ethernet device are DDD-N
DDCMP (serial lines), CI and DSSI devices are DD-N-M
Where D is a letter and N and M are digits.
Ok, so I see a trend here. All circuit names have a dash in them. That's how I was going to filter them out but I think I found a better way.
Thanks!!

With the common dash, check out the f$element( ) function in DCL. Very handy.
Apologies if someone already mentioned it. I jsut scanned through about 100 HECnet messages and I'm blurry.

My first retrochallenge entry http://www.wickensonline.co.uk/retro/documentation.html included processing DEC/ANSI escaped output from ALLIN1 and producing HTML using TPU (Text Processing Utility). If things get hairy this is a very VMS way of doing text processing.

Agh, magica. Those were the good old days. :)
What was that monster MIPS box you had that you terminated the serial tunnel on? Wasn't it the one that came in the same style as the VAX 6000?

Fun story:
A number of years ago I had a russian guy who asked for a guest account on Magica (MIMs predecessor, a real PDP-11/70, which is still around).
A day or so later, the system had crashed, and I had received an email with an apology from the russian guy for crashing the system.
It turned out that he and some friends had a russian cloned RSX system from some old age, which they had done plenty of hacking and working on, and in the process had found some potential exploits. Curious as they were, they decided to check if those exploits were still around in the latest version of RSX, which they had not touched before. Since I had protected all the directories and source files from random access, they couldn't check the source code, but they could write programs, so they did.
And yes, the possible exploits and holes were still around, and thus Magica crashed. This was in V4.5, if I remember right. I thanked them for the information, rebooted the system and sent what they told be on towards Mentec. The russian promised to not do that again, and I just thought it was fun.
V4.6 fixed one or two of the problems, but a couple of them are still around.
So, once it a while, you actually do find someone who knows what they are doing, but such people are normally not evil.
I'm still looking for script kiddies trying to hack MIM. Once in a while I do get people who try to login repeatedly as root, falken, and other known Unix accounts. Poor kids... ;-)

Only some machines have guest accounts and as far as I know we have no
standard. This site does not have guest accounts. I do create accounts
on request for some of the machines. Mostly PLUTO::, because it is the
only RSTS/E system on HECnet, but it is not up all of the time. With

Multinet circuits are in the form of "TCP-x-y". Both "x" and "y" are
assignable and default to zero (0). I have been using "x" to denote
physical circuit and "y" to denote area end-point. This way I no longer
have to remember (or guess) what the other end is. SG1:: only has one
(1) NIC so in my case "x" is always zero (0).
DECnet LAN circuits are in the form of xxA-n, where "xx" is the
controller type, and "n" is the physical unit of that type (starting at
zero (0)).
And multidrop connections might be in the form xxx-yy.z if I remember right.
xxx is normally related to device type. yy in many cases are the number of the controller, and z the line on that controller.
And as usual, I might be remembering details wrong. :-)

Take whatever you need! The new version will be better commented and
not require the reboot. I will place a copy of the old version of the

I'm assuming .eqs. is rather limited (say the way = is in bash)?
Is there any sort of regex style matching available?
Short of that, is it fair to say that all circuit names in the output of
show known circuits will always be in the form of XXX-N for non-multinet

Nah.

Huh? I didn't follow that last part. Why would you loose the ability to use MOP and LAT when you change circuit costs for DECnet?

Actually that's a problem with DECnet - everybody _has_ to do their

circuit costs are individually defined per node.

I think it makes sense as well, as ethernet segments can't really separate costs for different next hops.
Might as well make them expensive so that ptp links are preferred when possible.
