[aprssig] Re: [Xastir] Investigation into TELEM packets (XASTIR)

I did another packet sniff using ethereal and captured just these two packets going from my PC
One from XASTIR as the transport and the other by hand from a telnet.

XASTIR sends to APRS IS (does not work) PCSAT2>BEACON,SGATE,WIDE,VK4TEC-10*,I:T#918,142,144,002,095,073,11111111,0001,1
When you send by hand (works) PCSAT2>BEACON,SGATE,WIDE:T#918,142,144,002,095,073,11111111,0001,1 

---------------- Testing ----------------------------------------------------------------------------

I connected to XASTIR on port 2023 using telnet and sent 

"PCSAT2>BEACON,SGATE,WIDE:T#918,142,144,002,095,073,11111111,0001,1"

192.168.1.100 ---> 210.193.156.78 (second.aprs.net)

findu.com reports nothing for this packet ***

But yet when I send by hand from telnet to the server 

linux:~/.xastir/logs # telnet second.aprs.net 14580
Trying 134.173.254.38...

Findu.com sees it 

PCSAT2>BEACON,SGATE,WIDE,qAR,AA6RR:T#705,024,027,235,015,015,11111110,0000,1

and here is the sniffer trap


# javAPRSSrvr 3.10b08 
user VK4TEC pass 21694 
# logresp VK4TEC verified, server Core-2 
PCSAT2>BEACON,SGATE,WIDE:T#918,142,144,002,095,073,11111111,0001,1 
# javAPRSSrvr 3.10b08 29 Sep 2005 18:21:43 GMT Core-2 134.173.254.38:14580 

So why does APRS IS not like this ? And why is XASTIR sending it ?


PCSAT2>BEACON,SGATE,WIDE,VK4TEC-10*,I:T#918,142,144,002,095,073,11111111,0001,1
