FC2T2 experience & networking problem

Hi,

I have installed FC2T2 and have had some problems which I resolved, and
some which I haven't.

After my first installation attempt I rebooted and saw hundreds of
messages like:

   'denied {write} for pid=1 exe=/sbin/init'

Reading the selinux-faq in the release notes I tried adding 'selinux=0'
to my kernel boot options. Now rebooting gives a different message:

   'Kernel panic: Attempted to kill init!'

Back to the faq. Ah, reiserfs is not supported (but the installer allows
you to do 'linux reiserfs' to enable support) with selinux. So I
reinstalled and reformatted with ext3. Now I can boot, and things are
looking up :-)

Except networking is not working properly. I have a DHCP assigned IP
address via a NetGear router (this all works fine in FC1). I can ping
sites, but ftp or http just sit there. I disabled the firewall, set
selinux=0, but no difference. I tried using traceroute, to see if
anything was happening and I got the following:

# traceroute www.cosmiczoo.com

Then since ping was working I figured ICMP was too. So using traceroute
with ICMP rather than UDP gives:

  1  10.181.64.1 (10.181.64.1)  9.752 ms  49.872 ms  8.904 ms

  8  0.so-0-3-0.gbr1.oct.nac.net (209.123.11.233)  112.862 ms  79.463 ms

  9  209.123.182.243 (209.123.182.243)  79.304 ms  208.909 ms  78.218 ms
10  serv1.silverdns.com (66.246.86.2)  84.249 ms  80.537 ms  84.143 ms

Which is the right answer. This is about where my networking knowledge
runs out.


P.S. There's a typo in the URL in the release notes for the NSA faq. It
should be http://www.nsa.gov/selinux/info/faq.cfm.

Thanks,
