Just to add anecdotal fuel to the fire, I was using my installation of =20
horde from an ACS connection to my GCI connected Ubuntu server and it =20
seemed like every 45 seconds or so I'd have to re-login.

This is abnormal from what I'm used to at other locations. There are =20
some locations that I access this server from that I leave connected =20
and never have to log in again.

I've speculated that keep alives may be part of the issue, but haven't =20
done enough research to definitively say that the ACS part of the =20
connection was to blame.

I could go back to that location and do some sniffing but not until =20
toward the end of the month.
