RE: Flaky ADSL Connection/Disconnection Control

Hi Ken,

>You didn't say if the spikes in the graphic were for uploads or
downloads.

Here are those details
ADSL is a 1500/256 link. Red NIC Traffic is: Max Incoming: 60.3k Max
Outgoing: 4.9k

Are these "excessive", I wouldn't have thought so.

I have had another look at the graphs and there definitely seems to be two
disconnections a day, early morning requiring a reboot SOB each day and one
in the early afternoon requiring a reboot around 2.30pm. On the weekends
when there isn't anyone there to reboot, there is no traffic until the SOB
reboot Monday morning.


Thanks for this info, we'll look into it.

console of your smoothwall.

>If this is the case then in order to find the culprit you could control all
open connections.  There is a usefull perl script for this which can be
found at http://freshmeat.net/projects/conntrackviewer/ In order to control
the NATed connection then use "conntrack-viewer.pl -m" (naturally without
the "").  You should then see a list of all open connections including the
IP's and Ports.  You just then need to go through the list for computers on
your network which have a lot of open connections to different External
IP'S.  There is then a high chance that these PC's are running file sharing
software.
