My scenario is that I have a VPS with Apache (mostly for development of my own projects) accessed via SSH; and I time to time I would like to do a quick check just to be sure that there's no potential flaw I would not be aware of.
Most of the time I'm behind evil firewalls so I can't simply do an n-map from another (desktop) machine.
they never offer scan of a third IP---only the very same IP that is requesting the scan via the web interface (obviously because that could be easily abused)
since all (that I know) have web-based interface, it's quite complicated to use them from SSH command line (unless you're a lynx/links freak); particularly, scans cannot be easily scheduled or called from a test script
Is there an equivalent to these services that can be used for a single machine, via command line, or other terminal-friendly interface?
Edit: I'm starting to think I might be looking in the wrong direction. Or that the service is yet to be offered ;)
But to make it clear, idea of such scenario is:
I make agreement (and pay) provider of this service, running on theirhost
I log in to myhost
Using a a CLI tool I instruct theirhost to scan me (which and how scans they run is their know-how)
Either directly or e.g. via e-mail, I receive results
