background for them......
There are plenty of problems with the Linux LAT code (this isn't
DECnet). I tried looking at it a few years ago, but decided that it
would be easier to rewrite all of it instead of trying to fix that code.
But then I got sidetracked (as often happens), so I haven't done
anything about it.
Several people have already come to that conclusion, including me! It was written while I was reverse-engineering it so it's built up as a heap of guesses on top of other guesses. It works most of the time, to VMS, but as I didn't (and still don't) have anything else to test against that's where it stayed. I don't even have many DECservers to test against any more, my 90s power supply died (twice) and the 200 melted after the fans broke down :-( So the code languishes in its current state.
I also happen to think that C++ is a bad language choice. :-)
But it don't seem that many people are inclined to fix this. We'll see
what happens in the future. The LAT specs are atleast available
nowadays, so it should be easier to do this "right" now.
That said, I have also had problems with the Linux DECnet code.
Christine might remember me complaining in the past. :-)
It works fine with VMS, but horribly with RSX (which also is true of the
LAT code).
Although I've not tried doing much with Linux DECnet to RSX it's always seemed to work for me when I have tried it. I suspect that any problems here are much easier to fix. Even though the main protocol is in the kernel (unlike LAT) it's pretty solid code, so anything that needs fixing will most likely be in userspace. Most (though not all!) of that was written from proper specifications so should be easier to work with than LAT.
I think it's all userspace programs that I have had problems with.
Then again ... I've not had any bug reports from anyone about either and it's quite hard to fix bugs you don't know about :-P
Sorry, you're right. I think I've only talked with you on perhaps rather
vague terms about the problems I've had.
But as we now have HECnet, this is way easier to work on.
I suggest you log into MIM, and then just try to do a few different things:
1) Try phone to a Linux box. Initiated from both sides.
2) Try accessing files from both sides to the other side.
Neither of these things worked when I last tried.
And that's a start atleast. :-)

The one you really want is the DECserver 932. It's dense.
Peace... Sridhar
I've got a DECserver 900TM which works pretty well but I've noticed a pretty significant lag/poor performance when I use the TCP/IP connection. It's the only one I've ever had so I don't know if it's typical for these units or if I have a problem.

Guys,
I will most likely be experiencing some downtime next week due to an
upcoming house move, probably Thursday - Saturday.
This will mean that:
- GORVAX will be down, so anyone routing MULTINET through it will be
down as well
- CHIMPY will be down
- The IP addresses used for GORVAX's MULTINET and my bridge to Johnny
MIGHT change - the ISP has not confirmed or denied this.
However, on the plus side, the new apartment will have dual 20 down/2.5 up
DSL links with a load balancing router.
In addition to this, I have had a 47U rack* installed into a spare room so I
will be able to bring some additional hardware online, including:
- CHIMP. AlphaServer 4100, 2 CPUs with 2 GB of RAM and about 120 GBs
of disk
- RHESUS. Itanium rx2600 with dual 900 MHz CPUs and 8 GBs of RAM,
300 GB or so of disk.
- MKYVAX. VAXstation 90A, not sure about the config got it off ebay

- A DECserver 200 with various toys attached including some Amigas

Accounts will be available on all of the above to anyone interested.

I hope your move goes well, and that there isn't any problem with
setting up everything all over again. And that nothing throws a simian
spanner into things as well.
And as for that terminal server, should you manage to find another
one, please see how much it weighs and how much it would cost to send
it to this side of the pond. (If I can find the room for it....)
