Wow, this has been a LONG time. I no longer operate this network or the same machines - even that Ubuntu box is gone. So, feel free to close this, as I can't give you any tangible data to see what the problem ever was.
I will stand by my belief, however - whether it was the routers/switches in my office - something about that Ubuntu setup took down my network! Thanks for getting back to me -albeit a couple years late ;) On Tue, Feb 28, 2012 at 7:18 AM, Mathieu Trudel-Lapierre < [email protected]> wrote: > Well, be obviously fail here on the "promptly" part. > > No, not having web access because of the installation is not a security > vulnerability.
