I just posted a quick update to YAMon that fixed an issue with one of the iptables chains (that caused local traffic to get incorrectly tallied). It has been fixed.
Thanks for the update. I ran the installer and it hung executing #21 (Create YAMon init script in /etc/rc.local?). I typed 1, pressed return, it never finished. Running 3.8.5 on my Omnia. Ctrl-c ended the script after I waited 20 minutes.
