Used etherreal, watched ppp0, saw the desperate attempts at resolving the 

(Open (human) palm meets forehead, slapping sound wakes dog)

It was the DNS - I had totally forgotten that these private IP addresses
used for the PC to Palm ppp connection weren't registered in the LAN's
DNS, and since I was NATing out, the rest of the LAN never saw them,

Rather than go fiddle with production servers and DNS setups (admin has 
teeth), I decided to try it giving *only* the IP address in the Primary PC 
setup on the palm, and no name (i.e. I removed wookie.exocore.com, leaving 
Primary PC name blank).

Tweedledee! Worked first shot! Jpilot and pilot-link rock!

Only caveat - I find that I have to hit jpilot's sync button *before* I 
start the hotsync on the palm. Kind of confusing for a guy who has trained 
himself to hit the jpilot sync button only *after* hitting the hotsync 
button on the cradle ;-)

Without the name specified, worked both with and without specifying IP
address with net:, but good point for another reason - specifying the
interface will prevent some random Palm on the LAN from syncing with my
jpilot ;-)

Hey cool! If your hack fixes that issue, it would certainly make life 
simpler, especially people trying to script something, the way I am trying 
to do right now. 

I have been struggling with a way to get hotplug to kick off a ppp connect
if it sees a Palm come online on my USB port to get around the "Failed to
open /dev/ttyUSB1: No such device" issue. This was what caused me to go
look for a network hotsync solution to begin with (since the port would
never be free for a normal hotsync if pppd is running), which lead to this 

Would appreciate getting the patch and your network-sync stub program.

(You wouldn't by any chance also have a stub to kick off a network
connection one-click, to avoid the prefs>network>connect routine, would
you? ;-) )

Many many thanks!
