Well, do you know if you'll get different addresses often? Many
ISPs
give
dynamic IP addresses, but you actually stay on the same address for
months,
which makes it a rather small problem. I haven't had a change in
address
in
over 6 months myself.
And even if you do, with dynamic DNS you still have a hostname that
stays
fixed. All you need is for the things that connect to you, or check
your address, to be able to deal with names.
Well, they also need to recheck every so often... :-) My bridge
program,
for
example, only do name resolution when processing the config file.

I built the user mode router to do periodic DNS queries asynchronously
so it will automatically get updated, provided you use a service like
dyndns, and without any pauses waiting for DNS to respond.
Hello!
Robert if I remember correctly, it was originally built to run first on a
R.Pi
device, and as a service on Windows? (That should be a statement not a
question, but I'm surmising my way across this
thread.)
Actually my primary platform is Windows, so that is where it is tested most.
I have also run it on the R.Pi but not that much to be honest. Others have
played with it on various Unix flavours.
Regards
Rob

Well, proxy is something that needs to be enabled on both sides for it to work, so it definitely involves passing some information in the packets. So it has to be documented somewhere. Keep searching.
I don't think so. RSTS has no notion of proxy, but I distinctly remember having proxies on VMS work when accessed from RSTS with no access control specified.
No. It has to be enabled on both sides. Easy to test. If I just turn off outgoing proxy on a VMS node, proxy access does not work on RSX for the incoming connection. No matter what I do on the RSX side.

Incidentally Cory and Dave they are back. Right now there's a big glut

In all cases, if account information is passed in the request, it is used. For any OS. If no account information is passed, but both requesting node includes proxy information, and responding nodes make use of proxy information, this is used to get an account under which to process the reqeuest.
With VMS, if a request comes in without any account information, VMS applies the default account as the user under which to run the request. The requesting node have no involvement in this.

A variation which some OSs might use (I forgot) is to handle the case where a user name is supplied but no password.
I wonder what the expected behavior of that should be? Seems like just failed access to me (unless the account actually have an empty password).

Ah - and 11M+ can't do this? Didn't know that... Thanks.
Right. No RSX have any default account for DECnet. However, M+ have proxy, which can be made to work pretty close.
