OT: Centos 6 question

Thu Dec 22 20:46:32 GMT 2011

Oh, and if you reboot the server it'll load the default rules again - 
which are "allow SSH and that's it".
You need to do something like:

echo "# I did this to get rid of the default rules" > 
/etc/sysconfig/iptables

... as root in order to wipe the defaults.
