Dear Kind Folks,
  I recently updated one of my machines at work

which

was running Fedora Core 3 to kernel-2.6.12-1.1381

via

yum.  When I rebooted and booted to the new kernel,

I

fired up firefox and could not load yahoo webpage.

I

tried google, Fedorafaq, Distrowatch and nothing.

I

suspected Selinux could be the culprit, so I did:
Hat -> System Settings -> Security Level and

disabled

selinux.  Rebooted with new settings and viola I

could

see yahoo, distrowatch, google, etc.  I went to
terminal fired up yum and yum update selinux and

gave

me error message.  I tried again this time with
selinux-targetpolicy? (not to sure) but it went
through.  I reenabled selinux, and rebooted and

could

not view any webpages again.  I will get back to

the

machine on Monday, and it makes me wonder about

what

do I need to do, which updates I need to run.

kernel installed ->	[kernel-2.6.12-1.1381_FC3.i686]

I read very carefully the FAQ for SELinux from http://www.nsa.gov/selinux/info/faq.cfm

but I am still clueless.  I would like to keep

selinux

enabled and still view webpages.  How can I still

do

that?

post to the fedora-selinux list with the AVC denied

messages in /var/log/messages. Fedora SELinux FAQ is available

from

http://fedoraproject.org/wiki/Communicate
http://fedora.redhat.com/docs/selinux-faq/

Rahul
