Nice little shell command to get a real-time list of the top IP's hitting your site at the moment...

[b]tail -50000 access_log | awk '{print $1}' | sort | uniq -c | sort -n | tail[/b]

The -50000 says look at the last 50000 lines of the access_log file. You can tweak that if you need to look at more or less entries.

Helped me today when I was getting bombed by "omgilibot" essentially nearly bringing my server down. I was able to pinpoint the little sucker in seconds and add them to my firewall block list.
