This one is perplexing the devil out of me, but I'll bet will be easy
for the "right person" to see.

I have built 0.8.3 on two identical Linux boxes, both running 2.3.41 on
AMD K6/350s.  On one machine it works beautifully; on the other, when I
try to begin a capture, I get the following error in a warning dialog:

"The capture session could not be initiated (socket: Invalid argument). 
Please check to make sure you have sufficient permisisons, and that you
have the proper interface specified."

I *thought* both machines basically had identical software; both are
recent Slackware 7.0 installs.

Two clues, neither of which I know how to properly interpret:

Each time I invoke the program, I see a message like this in
/var/adm/messages:

> modprobe: can't locate module net-pf-17

Also, upon bootup, I also see the following message as part of the
sequence on the screen:

> ethereal uses obsolete (PF_INET,SOCK_PACKET)

Could somebody out there point me in the right direction?

Thanks in advance.

B.

p.s. The identical build on the other machine runs perfectly.  So
*something* must be different. . .
