Terry Trapp (KE4PJW) put up one that uses the whois service to run the
queries. He's not advertised it (well, I guess I just did) but then
again, we're not sure how useful this could be. If you have a whois
client then you can do:
whois kg4nrc@whois.nashvilleaprs.net
will return some info on me. It does not have license info, it's just a
simple name / address return. If this is of interest we'll see about
making it publically available and advertising it accordingly. Likewise,
add that additional information such as what was listed in the other email
about this subject. Likewise, if there are features you'd like to see I
think development could be accomodated accordingly (is there anything APRS
specific that needs to be presented? I'm not familiar with the APRS
callsign server).
Cheers,
Sean...

I don't believe it is up. I can't help you with who it was that ran it
though you might be able to find out by searching the archives. In lieu
of that, however, many APRS+SA systems are set up to act as a callsign
server. For instance, you can send a message to AE5PL-10 like:
l:N4BSA
or
w:n4bsa
Case is important for the command but not for the callsign. l (lower
case L) returns a two line response with the name and full address from
QRZ. W returns a single line response with the name and city/state from
QRZ.

What I think would further this idea is a simple daemon-like program
that does precisely one thing: interconnect a TNC to a core server. It
has no GUI. It lives in one process with no multithreading and simply
connects a single TNC to a single core server handling basic gating
requirements. It should be freely available to the community. It must
be reasonably portable so it could run _native_ on Windows, Unix, etc
without too much effort. By portable I mean written in C and no bulky
emulation layers. i.e. not Java Think: bootable floppy disk
Does anything like this already exist?
If this email has any point at all it might be to know whether this idea
is even worth pursuing if I did find some time to work on it.

Most aprsd users are using it as an IGate only daemon. Yes, it has the
capability to be a hub, but it does the IGate stuff well, and the hub
functions of the program take no resources unless you use them.
An IGate is not that simple a program, with the two way features that must
be implemented it takes a fair amount of work. You probably could strip
them out of aprsd, but again, why bother, the rest of aprsd does not
consume resources unless you use it.
I don't know offhand of any floppy boot system that would give you an IP
stack that would be useable for an IGate, but there may be a stripped
version of Linux out there that does this. Certainly Knoppix could do it
with a CD boot system, you would need to burn the disk for each use though
with a separate config file for the IGate (or use Knoppix's persistant home
directory feature on a floppy).

Agreed. I volunteer to assume the leadership role in coordinating the
javAPRSSrvr Tier 2 APRS network. Contact me if you have any questions, or
are interested in taking part in the Tier 2 coordination effort that is
already underway.
