[WT-support] Network problem, explosion of duplicates

[Tõnno Vähk]

Yes, with great help of K0DQ, N6TV and F6FVY the issue seems to be
identified.

 

The requirements for such multiplication to happen are:

 

-              One station in the network has to have both WiFi and wired
Ethernet enabled

-              Another station in the network has to be configured as SO2R

-              QSO has to be logged on SECONDARY RADIO of this another
station

 

It is strange that it happens for secondary radio QSOs but that is confirmed
by K0DQ and me also now. Then the passive computer with two network channels
multiplies it and sometimes the network seems to get into very long loop.
Sometimes this passive computer just produces 2-3 identical QSOs.

 

If anyone can find some more interesting details with tests then would be
interesting to know. It does not seem to depend on op systems, station
identifiers, etc.. It probably requires more than 2 computers in the network
to create an explosion.

After off list discussion, it appears it can be caused by having both WiFi
and wired Ethernet active on a computer at the same time.

 

Just set the hardware WiFi switch to OFF, or unplug the Ethernet cable, and
the problem should go away as now you will have only one connection to the
LAN per PC, instead of two.

Hmmm. 

Can't it be something so simple as a L2 switching loop in your IP network
