After upgrading from FC6 to FC7 the hostid of my computer became 007f0100, which if I understand things correctly means it thinks that the IP address is 127.0.0.1, which it is not. I've checked the network config and it looks fine, and I can access the machine from elsewhere. The hostid is important as certain programs will not run if the hostid is incorrect/changed. Another machine, which was upgraded from FC5, had no such problem. Any ideas? Be smarter than spam. See how smart SpamGuard is at giving junk email the boot with the All-new Yahoo!
