My netbook has a rather vanilla installation of F15. I tried a new desktop. Wireless didn't work (long story, not relevant) so I manually ran network manager (didn't help). Then I rebooted back to Gnome. Wired networking seemed to no longer work. Actually, networking worked but no domain names could be resolved. After a lot of ineffective poking about (based on my deep understanding of how things worked in the good old days before NM), I discovered (with help) the problem. NM creates a new /etc/resolv.conf.tmp whenever it learns (through DHCP or whatever) what the name servers are. On my system, it could not manage to replace /etc/resolv.conf. /var/log/messages showed: <warn> could not commit DNS changes: (0) Could not replace /etc/resolv.conf: permission denied "ls -l /etc/resolv.conf*" showed nothing scary. But "ls -lZ" did. Something had labeled /etc/resolv.conf unconfined_u:object_r:etc_t:s0 instead of system_u:object_r:net_conf_t:s0 Fix: "restorecon /etc/resolv.conf" How the heck is an ordinary user supposed to figure this out? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
