Hi Duncan, 

Thanks for that advice.

I installed ngrep and am working on understanding how to use it to
debug this nntp triplicate-posting problem.

By way of advice to others on RHEL6 derived Linuxes (I'm on Centos 6), 
it's found in the epel and rpmforge repositories:
 
$ yum --noplugins --showduplicates --enablerepo \* --disablerepo 
c6-media,\*-source,\*debug\* provides "*/ngrep"

REPORTED:

$ man ngrep
(reading the man page for hints on how to use it)
