Hello Paul,

So are you saying that ax0, ax1, and ax2 all looked ok and you were able 
to make outgoing connections on each of them but after a period of me, 
ax1 disappeared?  Do you know when?  Maybe it disappeared after you
disconnected from the ax1 link?   This is a key detail we need to know.

> ax0 u433 ttyS8
> ax1 u439 ttyS5

What are these "u433, u439, and v70" terms?  Are those the device names 
in /etc/ax25/axports?

What program are you using to make these outgoing calls?  "axcall" or 
"call"?  Maybe something else?


What other packet software are you running during these simple tests? 
Any netrom, node, ax25d, ax25ipd, BBS, or other software?  Below it 
shows you might be running the legacy NODE program.  Yes?

Above it shows you're bringing up ax4.  Where is ax3?  As mentioned 
above, we need to know WHEN ax1 disappears in relation to bringing up or 
using these other interfaces.  I'm suspecting you have a conflicting config.

It seems this remote station, G4APL is coming *into* your station and 
then maybe after that things break?  How is this remote station coming 
in.. via AX.25?  via Netrom?  Via IP?

Is this coming from your node program?  How are you accessing the node 
interface?  Are you telnet'ing into localhost on a specific port?  If 
that is the classic LinNode software then I don't understand the prompt. 
  Your machine is GB7CIP but this prompt is showing you're currently 
coming from "GB7CR:CRNODE"


Anyway, there is another thread going on the Linux-hams list on Vger on 
how the LinNode software is pretty old.  Seems that thread mentions a 
known "looping" bug which I think should should be fixed but I don't 
have any details on that.  Regardles, I too would recommend running 
UroNode instead of the LinNode software:
