Re: [gentoo-user] HELP! Network status changes randomly, how to diagnose?
Sounds like you might've been trojaned in some weird way. Do you update regularly? If you run out of options, maybe a complete reinstall (to be sure) would be in place. Is there nothing unusual in the logs? -rz -- gentoo-user@gentoo.org mailing list
