error log with strange message

[z3r0]

Hi,
can anyone tell what this error message telling me to do? It's in /var/log/apache2/error.log

[Fri Sep 16 16:35:56 2011] [error] [client 10.123.33.122] File does not exist: /srv/www/htdocs/sugarcrm/error

You are right, that's really strange.

I suppose anyone who tried to test (hack?) your server looked for a hint how to open the door of your system.

Most times these guys look for something like ../phpmyadmin, ../phpMyAdmin,... and so on.

As this entry is logged in the error.log your system worked right and denied his access.
