I got 1 response in a private mail on this, but the information wasn't quite what I was looking for, so I'll try again.

We have a server running a bunch of vhosts, and people have various php/pearl/etc. scripts on their websites. We know there are voulnable scripts on some of the websites, but Nessus doesn't find those, because it's just scanning the web server itself.

I was hoping that the use of ip[domain] would make Nessus able to scan the vhosts directly, but as said it didn't quite do that. Am I misunderstanding the mail below, or something?

Maybe Nessus isn't the right tool to do this, but in the past we have had a lot of good use from Nessus, to find a bunch of poorly configed servers. But maybe you guys can recomend a better tool for this type of web server scanning?

I'm looking for a way to scan for vulnerable php-scripts and alike. I'm
trying to scan my domain on my webserver, but I can't quite get Nessus
to do it. It scans the webserver just fine, but it seems it's not able
to scan the vhost running on it.

I've found the mail below in the mailing list archive, and from that I
gather that I should just tell nessus to scan "127.0.0.1[www.foo.bar]"
(with my IP/domain in it), and that's what I've tried. But it still just
scans the webserver itself.

I'm wondering if I'm getting this wrong, and that Nessus arn't able to
do what I want, or if I'm doing something wrong? I hope you guys can
help me out.

No, you just need to enter the name of the target host and that's it. If
the DNS<->IP has not been done it (ie: because the server has not been
put in production yet) you can force it in Nessus by giving the host
name between brackets. Ie: "127.0.0.1[www.foo.bar]" will test 127.0.0.1
and all the HTTP requests will have the Host: header set to www.foo.bar.
