This is more of a search for similar phenomenon rather than a SOS - incident been too weird to be solved.
Till 2 days ago I could connect to the net using a realtek lancard on a Opensuse 10.3 system. Then abruptly, the day before, I could not connect. The card was being recognised and the network monitor showed that the connection was up, but I could not get any site to open. The ISP reported that the system was not to blame. Disabling the card and reenabling it, deleting and recreating a new connection all were tried out to no avail. Probably the DHCP part of the connection could be to blame, or the DNS configuration wrong, but using the default, automatically set values worked fine till that moment.
Now the real fun part : I tried Kubuntu and Mandriva live CDs and in both cases I could not open any site, though I did not try to manually set network settings. But with a Belenix 0.6 there was no problem, and I could go online as if nothing had happened, again using the automatically detected network settings.
The windows user in me tell me a "repair reinstall" should work. But I do not find anything else wrong with the Opensuse installation. And given than Kubuntu and Mandriva are also facing the same problem, I don't think Opensuse is to blame either.
Can anyone shed some light on this "X-file"?
