I installed wine in fedora (mate), follow the download and installed the img burn, all good, just made copies of a dvd on the computer and just press a button, do not remember exactly what, a yellow table (top right) and give me two options ignore, I do not remember the other, I closed the table (rather than are figured out 'post had to push ignore), and at the same time I pulled the wireless connection of internet, ANY red (prohibitive) table disappeared and the icon wireless network, but I had internet normally, not simply seemed icon. Some point while trying to restore it through the firewall, tweak some settings and the outcome is not I have no internet. While normally restored the settings in firewall, (observing to live cd) internet no. Ans' I understand, if you reset the firewall as shown here default , (from live cd) will i have to internet, (because so it was when it opened for the first time the firewall), but however much I try I can not get by with anything, so it is now without internet. Please help; Thank you.

So far, I see nothing in your post to explain why you think SELinux is the issue. Are you getting alerts from the troubleshooter? If not, open it up (It should be on the System Menu.) and make sure that it's set to give you alerts. If it wasn't, set it that way. Also, see if there are any alerts listed that haven't been dealt with. If not, SELinux isn't involved in your issue.

Thanks for the reply. First, I got notice from selinux (for possible consider some movement of the program - imgburn- as a threat),but i the delete, why the first time i face similar issue. But now, and after this incident I have no internet. Can you recommend a solution, about what I said, because despite persistent efforts I have no result? Τhank you.

That alert that you deleted probably told you exactly what was wrong. Now, of course, there's no way of telling. Sorry.

sudo ausearch -m avc|audit2why should help. I advise you to use applications already in the Fedora repos, especially for such common tasks as burning disks; they generally don't have these problems. sudo fixfiles onboot will relabel on next reboot, a good idea for troubleshooting.

That said, an ingored SELinux warning probably did not kill your networking. Please try to provide more information about the network problem. Update your question with the output of these commands:

  • ip addr
  • ip route
  • ping &ltip address of default route>
  • dig fedoraproject.org

Thank you, randomuser; live and learn. Nti-nos, you might also want to try this: ping 23.48.166.151 and see if you get any results other than No route to host.
