Okay, a lot of confusing stuff is happening. I'm going to try to note this all down in an ordered fashion.
1. I tried 'service network restart'. eth0 still shows up in ifconfig. I don't see eth0 or eth1 anywhere in the directory.
[root@localhost network-scripts]# ls
ifcfg-lo ifdown-ippp ifdown-ppp ifup ifup-ippp ifup-plusb ifup-sit net.hotplug
ifdown ifdown-ipv6 ifdown-routes ifup-aliases ifup-ipv6 ifup-post ifup-tunnel network-functions
ifdown-bnep ifdown-isdn ifdown-sit ifup-bnep ifup-isdn ifup-ppp ifup-wireless network-functions-ipv6
ifdown-eth ifdown-post ifdown-tunnel ifup-eth ifup-plip ifup-routes init.ipv6-global
2. I tried 'ls -lt'. only 'cron', ' Xorg.0.log' and 'messages' were recently updated. But for these I saw no correlation with my attempt to access google.com in mozilla.
3. 'messages' however, kept filling up with the following msg, and is repeated several times per minute.
Feb 28 18:07:01 localhost dhclient: DHCPREQUEST on eth0 to 192.168.1.1 port 67 (xid=0x7638d090)
Feb 28 18:07:01 localhost dhclient: send_packet: Operation not permitted
I rebooted and this stopped. (i initially tried service network stop, without success)
4. I tried '-type f -mmin -1' to see if any files changed recently anywhere on the system.
This returned only a large number of files from the "./proc/" directory.
5. The weird part now. I have internet access. I thought it might be due to the reboot. but doing 'cat /etc/sysconfig/iptables' reveals the same config as in my previous post.
(On subsequent checks, the [x:x] values in the first three lines change, as I wondered about in the original post.)
I was sure that it didn't work before.
To make it fail this time around, I can either add "-p tcp" to the INPUT rule, or I can change --dport to --sport.
Do you know why sport wouldn't work? Doesn't setting dport mean I'm configuring for a port on an outside (destination) computer, thus assuming they used port 80?
6. Would it help if I started over? I don't really want to reinstall everything, but if I had to do it, now would be a good time since it's a pretty fresh install.
