Not a vulnerability, just for information's sake. Please don't turn
off all ICMP, that breaks more things than it fixes.

Someone fetched /robots.txt which is a file which says which
(well-behaved) web crawlers are allowed to access web sites. Google
amongst others will do this - in which case you should see "googlebot"
as the user-agent for the /robots.txt in your httpd logs.

If you want to know more, check out the references in the signatures.
