AX25 Node problem - please help

[Roger Harris]

Hi

I've been trying to post full details of this problem to the mailing 
list but my messages don't seem to be getting through. Perhaps there's 
something in the body of the message that the system doesn't like so 
here is a summary in the hope that someone may recognise the problem.

I've recently noticed that a particular set of events can cause the node 
to go into an endless loop. I have noticed this with node-0.3.2-4 on 
Fedora 9 and node-0.3.2-14 on Fedora 20 so I'm assuming that it's a bug 
which has always been there. Note that these are the distribution 
(unpatched) versions.

Does this sound familiar to anyone? Has it been reported before and is 
there a patch available? I'm happy to correspond directly with someone 
with full details including strace info etc. in order to get this fixed, 
but I don't know who is looking after the node software these days.

Many thanks

Roger G3ZFR

Hi again

Many thanks to those who have replied to me personally on this.

It would appear to be a known problem. Brian N1URO has fixed it in 
URONode but I believe that it's still a problem in the original node.

Anyone who notices the node going into a loop and using unnecessary 
resources should consider using URONode instead.

Thanks again

Though I too recommend UroNode, could you tell us more about what you're 
seeing in this "looping" issue with LinuxNode?  If it's a real bug, we 
should try to get it fixed as that software is still commonly used and 
available in various Linux distributions:

    Ubuntu: http://packages.ubuntu.com/lucid/hamradio/node
    Fedora: http://koji.fedoraproject.org/koji/packageinfo?packageID=6606
    Debian: https://packages.debian.org/stable/hamradio/node
    etc

yet UroNode is *not* included in most distribution packages per the 
request of the developer.

Hi David

Not being a regular contributor on here, I'm unsure how wise it would be 
to give too much away about how to crash the system, especially as this 
forum becomes public when it gets archived.

I'll email you directly with the details. Please feel free to post it if 
you feel that it won't do any harm.

I'll do the same for any other developers who want the details.

Cheers

Roger

Okay, what's the logic in that?  If UroNode fixes a lot of the problems 
in the original "node" package, why package it up in the distributions 
where it will get wider visibility and coverage?

I'll admit I hadn't even heard of it until Brian Rogers mentioned it in 
an earlier thread, with a link to it on an obscure FTP site.

If this is Brian's whish we can not argue.
BTW: Brian Rogers = N1URO = author of UroNode, in case the link is not clear.

I had an email thread with Brian many months ago where he previously had 
some personal objections of how some distributions compiled things 
incorrectly, created specific support issues, etc.  I think previous 
versions of UroNode called out those objections in the LICENSE file but 
it seems both 2.0 and 2.1 have that file removed in their respective 
archive:  ftp://ftp.n1uro.net/packet/

It might be work asking him again as his UroNode software really is a 
significant improvement over the old LinuxNode package.
