Ok, that is good! I once tried this with NETCHL and it failed, and I did not
want to spend the effort of going through all code to make it 64-bit secure,
and this is a waste for such a program anyway (it does not require large integers
or pointers that can access more than 2GB).
So for NETCHL the -m32 flag is mandatory.
Of course, with Debian8.7 there still are several compiler options (4.6 - 4.9 and
maybe more) so there may be some issue with a different version of the compiler,
I have seen that happen in the past.
Otherwise I have no clue what could be happening, we would need at least the
stack backtrace and maybe more.

As you mention JNOS I presume you are not using the NET/ROM code built into the
Linux kernel, but run JNOS as a user program on some tun/tap device.
This means, this problem has very little to do with Linux. It is just a bug
in the code, maybe combined with a property of the compiler. It sometimes happens
that when you compile C code with a newer (or another) compiler than the original
developer used, bugs surface that have always been present under the carpet.
What happens when it crashes? Segmentation violation? That would indicate
a corrupted pointer or -memory. When you type "ulimit -c unlimited" before you
start the program you will get a core file (memory dump), and you can find out what is
happening using gdb. Of course you need some insight in programming, but
it could already help when you just print the stack backtrace (bt) and post it here.
I have no personal experience with JNOS under Linux but it kind of surprises me
that nowhere in the makefile or compile document there is mention of "64 bits".
I would compile a program this age in 32-bit mode (my NETCHL also requires this),
and that would be done by adding -m32 to the CFLAGS and installing the 32-bit
development libraries first. But I leave it to others to comment if this is
required. Unclean code could fail in the way you describe when compiled in 64-bit
mode and work perfectly in 32-bit mode.

Hi All,
A couple of weeks ago I downloaded and compiled jnos2.0K and found that
while the compile appeared to be successful, jnos would crash when a nodes
list was sent or I entered "netrom bc xxx"
So I have learn a lot about linux since then but not yet found the problem.
I compiled using Fedora 24 with the most latest updates on two different
PC's and today downloaded the gz file again.
A kind user has helped enormously and sent me a file he compiled last
December 11 (I think) and it runs well.
Jnos2.0i compiled here today also runs well with no problems using my same
config.h file.
So it seems that something has changed with the "netrom broadcast" source
file since around December.
I have discounted Fedora mostly as jnos2.0i still compiles good so a side by
side source file compare is the next do.
The question is then, has anyone else had netrom crashes after a recent
Fedora jnos2.0k compile please?

Well, it should be mentioned that going directly for BGP routing and mentioning
that you are an ISP is probably not going to speed things up!
It would be advisable to start experiments with IPIP tunnels or other connectivity
and add BGP routing later, as a service to local hams only.
There are lots of requests for large blocks to be BGP routed for AMPRnet that really
are attempts from ISPs to get IPv4 space that they can no longer obtain from the
normal registries, so this kind of requests and formulation will make the
coordinator very wary...

What's the timeframe to get a block of IP's, I'd like to start testing
and messing around with AMPRnet. I've got BGP routing available, and I
can't wait to get connected.

Hello,
I have linbpq32 setup and would like to get more axip connections and chat
links. I also would like to get some messages flowing my direction.
Could anyone help? I can give you my MAP line...

Hi All,
Since compiling JNOS2.0 some years ago, I have always had problems with
Netrom transmits killing it back to the directory prompt.
I have been using JNOS1 version ? in its place for a long time because of
the same problem.
But today I downloaded and compiled the latest JNOS2.0k and have the very
same problem.
It all compiles ok on my Fedora (latest updates) it starts and runs
perfectly until it does a node transmit and dies immediately.
I can poke it with all the netrom commands until I do "netrom bcnodes port"
and it crashes.
It receives nodes ok and populates the list ok. It also does normal "Connect
XX VK1KW-5" ok.
So to try another idea, I removed all my netrom options from autoexec.nos
and used the defaults. (except interface /call/node name). Same problem and
crashed.
I notice also in this version, you need to type the whole word eg "connect"
vice "con" or "ifconfig" vice "ifc".
Maybe something in Fedora is not compiled in or is missing or I haven't read
enough yet.
There may be a conflict in my config.h but it's pretty much the same as
original.
So I am open to ideas.
Thanks in advance
Regards
