That is easy. Just change the source before compiling, and there you have it. Definitely a compile time thingy, and extremely easy to "fix".
If you could make it a compile-time switch for make it would be very-much nicer :) just something like 'CONFIG_FILE=/etc/hecnet' or something with a commonly usable default value in case you forget to specify it or don't want to change it.
Also would it be difficult or counter-productive to roll the Port configuration into the config file instead of having to specify it at runtime?
If you don't want it on the command line, you can just assign it in the code as a constant. Very easy. :-)
That's easy for you to say, you're a coder. I don't code C at all and wouldn't know where to start, so if anyone else fancies na 'easy' challenge then make it so :)
I wouldn't want the port number hardcoded as it's configurable for a reason (it's a good thing), so it would be nice to have it read from the config file instead of having to remember it on the command-line.
Lastly does anyone know how to roll a init.d script for it to set it as a service in Debian/Ubuntu (10.04)?
Not sure which variant of init debian uses offhand, but in general you just write a small shellscript that don't do much more than just run the command line the same way you do by hand. Grab some other simple service and copy the startup, and then change the command line.
It's ridiculously simple.
That I might be able to do. I'll look into it while I'm working out how to make one for SimH. Again though it's something I've not played with so some helping hands along thew way would be nice ;)
I am going to have to try and write up tutorials for building the VAX and PDP-11 machines I have running as there isn't an up-to-date and comprehensive tutorial for either, aside from Phil Werry's which is dated a little and very hard to read as it's very long and not broken up at all.

Feel free. It's not overly complicated. However, make that optional, as maybe not all want that enabled. If DNS lookups take a while (which they definitely do when DNS is having problems), you'll hang the bridge while it's trying to resolve stuff.
It would also be nice to make the code a bit more portable so that it will compile and run on more platforms without modification, a bit like SIMH.
Any changes to make it more portable are always welcome. Just make sure you put the stuff in conditionals, so that the same source still compiles and works on the other platforms.

Did you document the changes? I want to try and port it to VMS.

Subject: [HECnet] Windows Version of Bridge
I just wanted to let you know that I have ported the bridge code to Windows. It seems to work well for me. If anyone is interested in a copy, let me know.
I think that it needs just a little bit more work to do the following:
1. Tidy up some bits that I almost certainly left behind while trying to get it to work.
2. Turn it into a Windows Service so that it starts automatically when Windows starts.
Another feature which would be nice to add generally is something which periodically re-resolves the DNS names in the config file to IP addresses, so that people who use something like DynDNS because they don t have a fixed IP address, can use it more easily and not fall off the network for too long when their IP address changes.

Hello!
That's amazing Rob. Truly amazing. I've been stuck at that place found
in that cave adventure game, because I can't seem to figure out a
working method to connect something appropriate to the networking
setup that the list discusses.
Of course the next step for me, would be to setup something
appropriate...... Well maybe soon.

You have misunderstood what .END does.
.END means assembly stops there, and the argument is the start address
of the program.
So, your code for your PRINT routine is not even assembled. Make sure
you create a list file, and this should be obvious.

Fred, DEC tends over-engineer things so possibly one fan may work provided the box is not loaded with disks. The VS4k series were designed for 5400 rpm disks and not for 7200 rpm or faster running disks. My solution would be to put storage in an external cabinet.
You could try and apply e little graphite powder in the noisy fan bearing, better yet use a molybdenium based lubricant: these do not conduct electricity.
I haven't opened my VS4000-x0's for year and cannot recall what the powersupplies look like, sorry.

Onderwerp: [HECnet] VAXStation 4000/90A power supply fan
Verzonden: 18 november 2011 14:13
Good morning ...
Subject mostly says it all. One of the fans in my VS4K 90A is noisy. I'd
like to replace it. (actually both) Two questions arise:
How the **** do I get the fans out of the power supply? I've got the
power supply out (that's easy), mostly apart (that's not so easy) but do
not seem to see any screws on the fans.
Would it be safe to run it with just one (quiet) fan?
Any pointers or links would be appreciated.
Thanks,
Fred

Lets call it for what it is - "legacy" is a term that people use in a
polite but derogatory manner to imply that the future direction they
prefer is not that which they view as the current direction.
I'd caution against running it with one fan - I think the point of having two is in case one fails, and like hard drives it does occasionally happen.
Regards, Mark.
