Re: YAM transmit problem

Hi Jim

There are two things to check :
Verify if the HWaddr-ssid is unique for all interfaces (in this case -11)
and not set on other interfaces :
> yam0      Link encap:AMPR AX.25  HWaddr W6XE-11

Next check if this ssid corresponds to the /etc/ax25/axports file.
When the axports is correct pointing to this interface, you can confirm this
with listen. Listen should show the 'name' of the axports interface, not the
physical interface.

Ie : if your /etc/ax25/axports configures :
port1   W6XE-11        115200          255     7       KISS

Then listen should show the incoming packets marked as 'port1' and not
'yam0' :
port1: fm PD1ACF-11 to PD1ACF-5 ctl UI^ pid=CC(IP) len 49
IP: len 49 44.137.2.29->44.137.2.92 ihl 20 ttl 63 DF prot TCP
TCP: 3610->1054 Seq x7ab1128d Ack xb01b9cfc ACK PSH Wnd 16200 Data 9
0000  +OK 0 0..

Above is copied and pasted from my own running setup, only as example.

Next to that you can force some TCP traffic over your port :

#route add 44.1.1.1 yam0
and verify when you ping this 'host' if the transmitter is keyed :
# ping 44.1.1.1


Hope this helpes,

Ron
