Oggetto: Re: [opensuse] SuSE cannot restart internet services after network blackout A: "opensuse" Data: Venerdì 18 settembre 2009, 15:21 the whole building. After about 1/2 hour people were able to use the internet again. So was I on my wireless laptop but I am still isolated on my wire (Ethernet) desktop. Both systems are running Linux/SuSE ..... Someone here suggested that Linux looses sone network infor which is written in a /etc system file whenever the network service is interrupted abruptly. Is that true ? I tried to reboot but nothing changed. Why the wireless system has not been affected ? How can I retrieve the lost piece of data ?
Thank you so much, Maura
If one machine is working that's a good start point in order to begin investigations :-)
Check the wireless network configuration, especially the IP and DNS ones and then replicate it logically, on the wired machine.
Other checks must be oriented from the very basic standpoints as:
Physical connection from pc to router, switch, outlets...
What is the connection device from wired pc toward the outside connection?
The wired PC is connected through an Ethernet cable to the University server. Thank you, Maura

It could be that University server is offering DHCP service to the wired PC and that something has changed on the configuration(?) But before to enter into this section, verify all from the very basic: 1 ping from wired.pc to U.server 2 ping from U.server to wired.pc 3 ping from U.server to a internet address (ping google.com) 4 cat /etc/resolv.conf on U.server 5 ping from wired.pc to one of the nameserver of U.server resolv.conf If (as I am thinking) you are working, or you are member/student of a University, ask to an IT "old man" which can guide you better than whomsoever to discover and solve the problem.
