I think your best and safest bet would be to find a conference server that can use a proxy.
A service connected via a proxy has full functionality (this is different from a relay) and
there is really no disadvantage to having a service connected to a proxy hosted on the same
machine. Doing this, only the elproxy program has to open sockets for 0.0.0.0:5198 and 0.0.0.0:5199
and there are no conflicts.
Of course it would still be interesting to know if a program can be listening e.g. on 44.128.0.1:5198
(UDP) while another program on the same machine is listening on 0.0.0.0:5198 and will receive all UDP
to port 5198 except to address 44.128.0.1

My program does not listen on individual addresses. It opens a wildcard socket for
each port, receives the traffic and gets the addresses from the OS using special system
calls. That way it can run serveral proxies and relays using only very few sockets,
improving the efficiency of the select().
You can just move over the existing Java proxies to the C program. Stop the Java
proxies and add their addresses to the config file of the C program.
I have no experience with conferences, I do not know if they can co-exist on the same
machine with the proxies. Probably not. It is probably best to use a separate (virtual)
machine for them.
However, I am not sure. It could also be that having the software that opens ports at an
explicit address and these wildcard ports can co-exist.

Yeah I sort of remembered that, but I wasn't sure. Thanks.
(it might as well have been possible when the kernel first checks the specific address sockets and would fall back to the wildcard socket when none matches)
Unfortunately I have no experience with running conference software at all.
When a conference can run via a proxy, it can still be done on a single machine!
Just configure all the conference addresses as proxies, make these private, and connect the conferences to those.
All UDP I/O will be via the wildcard sockets and the TCP connects can be local on the same machine.
(selected proxies can be made private by configuring something like Password_51=mysecretpassword while the global setting
is Password=PUBLIC)

For everyone's info: I have updated the file at http://pe1chl.nl.eu.org/Softw/elproxy.tar.gz
(also available on www.pe1chl.ampr.org on net44) to include an init.d script example and
a logrotate.d config file. Everything else is unchanged.
I welcome corrections or suggestions for changes in the README file when something
is unclear. Make sure you follow everything written in the file as it is now.
(especially the part about sysctl and the proxy_message logging)
I should probably some description of what proxies and relays are and how they are used,
that was already sent to this list however.

Hello 44net,
Not sure who I should address this issue to but I guess it's to you please
Maiko.
Would someone reassemble the jnos2.0k.tar.gz file to make it easier to
compile and run please? It must be a nightmare for the newbie.
Problem is that the installer2.1 is not included in the jnos2.0k.tar.gz. The
correct files.h is not included, the tun.c file does not work and should be
replaced by tun_sp1l.c under Fedora 26 and others. All these have separate
downloads and driving instructions.
The nos.cfg file does not seem to be included in the 2.1 installer either,
and was recovered from a previous install.
Not to mention the too and froing from my home directory to root after the
install was run.
So on top of all that, and after what seems to be a good compile of
jnos2.0k, the NETROM function still does not work and crashes after the 11th
line of the first nodes transmission. Almost looks like a memory overflow
but there is plenty supplied in the "qlimit"
Have tried jnos2.0k after a fresh installer2.1 and just added netrom and
still crashes the same.
I have tried to get "k" working after many attempts, directory changes, in
root and home, etc, etc but directly replacing the compiled jnos2.0k with
jnos2i or jnos2h exec and netrom works fine.
The last time I tried to capture the crash it locked up the PC.
Is jnos2.0k transportable between directories other than named "jnos" (tried
that)
I currently manually run jnos2i in my home directory under sudo
successfully.
Is anyone else running jnos2.0k netrom successfully and what is the fix
please?
The reason for the revisit to jnos is because I now have 50Mb down and 5Mb
up thru new internet service provider NBN/iinet.
Many thanks

All,
I have made some extensive updates and edits to the OpenWRT WIki:
* Routes and rules are now included in the UCI
* The Startup script only sets up the tunnel and ampr-ripd, it has been reduced to 7 lines.
To do:
* Edits if ampr-ripd is added to the OpenWRT repo.

UCSD is swapping out some networking equipment and amprgw (aka
gw.ampr.org, 44.0.0.1) will be unreachable for a while starting
around 7pm Pacific time Thursday (tomorrow). It should take only
a few minutes, but as both the connection and configuration have
to be transferred to the new equipment, there is always the
possibility that it will take longer or something else may go wrong.

As you know very well, it always takes more time than estimated...
It affected our gateway since a script that downloads the DNS zone when
modified got stuck, halting a cronjob script that also performs other maintenance
tasks. Modified with some more safeguards... :-)

I still have a Mega ST4 with harddisk cabinet and original monitor sitting in a spare room but it rarely gets switched on these days.
(those were the newer pizza-box style ST and disk. the disk cabinet in fact is a 44MB swappable plus a fixed disk)
This one is fitted with an ethernet adapter I made (a PC ethernet card and adapter board to the internal bus) and I added a driver for it to KA9Q.
However, the card has BNC and AUI only and I don't have coax ethernet anymore. Should have an AUI to RJ45 adapter somewhere.
Also in storage there is a Mega ST2 with an 8-port Z8530 SCC card that we used for years on a major network node (TCP/IP and NET/ROM)...
(of course I had a 520ST as well but that one has long been scrapped)
