Add option to rescan services

[ikstream]

It would be great to have an option to rescan individual services.

If a single service's scans are botched for what ever reason I would like to rescan theses services. If we use the --overwrite flag we would rescan all services on all hosts, which might be very time and resource intense. Therefore something like below would be desirable in my opinion.

-r , --rescan 

e.g.:

python scan.py -i service.xml  --rescan http telnet ... 

One could delete the result files, but this might lead to fat fingering the deletion of additional files. This Could be combined with overwrite and used as --single-scan or something instead where only the provided services are scanned by recon, which might be the better option.

what about this:

• in case the user provides the --rescan option the given hosts/ports/services are re-scanned
• existing files will be overwritten; no need to provide the --overwrite_results flag

the parameters for --rescan are as followed:

<host>[:<port>[/<protocol>][:<service>]] [...]

If I have like 20 hosts that would need an smb rescan, because I forgot to change the enum4linux-ng command this sounds quite tedious to me

then how about using * if you don't want to specify a particular host/protocol/service?

--rescan *:*:http localhost:udp:* vulnerable.lan:*:*

[ikstream]

Let me put it in my own words to see if I understand your idea correctly.

• *:*:http would mean rescan all http tagged ports
• localhost:udp:* scan all UDP services on localhost
• vulnerable.lan:*:* Rescan all services on vulnerable.lan Always related to the content of the provided xml file of course.

If that's correct it sounds like a great solution to me.
