  Is your computer reachable?
Network Posted by Beat Rubischon on Wednesday April 06, @05:01PM
from the ping-pong-ping-pong dept.
Each computer attached to one of our networks is tested periodically for several known problems. On Thursday morning, we start with a new, much more reliable ping test. Please investigate in case you get a mail Technical problems. Currently 45 computers are affected.

Two reasons why your computer must be reachable:
  • The DHCP server checks each number before it is offered to a computer. In case a running computer is not responding, two computers could get the same IP number. This happens quite often in our small ranges of public IP addresses.
  • The central IT support probes each IP to detect the real usage of the network. We would lose our ranges in case too many computers would not respond.
You can test your computer yourself and follow our instructions for Windows XP SP1 or Windows XP XP2. MacOS X users can simply stop their firewall - it is needless as long as you don't have configured special features.
