I'm running FC2 now. I did a netstat and didn't see any connections
I couldn't account for.

I have set up for FC2 legacy updates, and done a

# yum update

which pulled several packages.

What should I do in order to defend against this sort of attack?
I'm not familiar with iptables, though I just looked, and it
didn't look like much was blocked. I don't have awstats, I guess,
as

$ su -
# man awstats
No manual entry for awstats

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
