I administer a network that runs approximately 11-14 Windows
installations, 3 Macs, and 1 standard Linux setup. I recently tried to
upgrade my Linux box to the Ibex. No problems, except My Subnet Mask
wouldn't stick in the Edit screen of Network Manager. I have each
machine on static IP, and hence, the need to input my own subnet. This
problem, however, exists in Opensuse 11, as well, so I figured
eventually I would perform a work-around as I've done in the past.
The problem wasn't the subnet, however, it's the fact that the Ubuntu
box actually disrupted my entire network! All my machines plug into a
basic, 24-port Cisco switch. Which feeds from a Dual Wan Router, and
two DSL lines. I actually replaced the firmware on the router, bought a
new switch, and called my ISP, all this before I realized the Ubuntu box
took it all down! Turned off the Ibex machine, and all was fixed.
I have no idea what caused this, as my entire network was down for the day-that
was my main concern, and I'm lucky my employer trusts me enough to know that I
would never intentionally put something on the network that would compromise
the work-machines.
It wasn't until the afternoon, when with a new switch the network again went
down, that I went over to the Ubuntu box and realized THAT WAS WHAT HAS CHANGED
IN THE PAST 24 hours!...
Just need to get this piece of information into the right hands, please
note this computer had a FRESH install of Ubuntu Gnome, no Samba config,
not even updated yet, as I couldn't get the subnet to stick...
Thanks,
Anthony M.
