I own a Linux VPS, which I use mostly for fun (to teach myself things etc.), while I also have some rather important services there, such as an email stack, a Jabber server, a LAMP stack etc.
I was thinking of an online service, which I could submit my server’s IP address to, and the experienced people there could check my box for any vulnerabilities, just for fun, while me having some degree of confidence that they won’t actually compromise the box.
Are you aware of anything like that?
I know what nmap is, so don’t suggest that.
You might want to check out Sitewatch, they have a free service.
