But I'm noticed some unfortunate performance characteristics in certain scans due to the way that ms-sql-discover and ms-sql-info are in the "default" category and have hostrules which basically match every host. So say I want to scan for web servers and run the default web-related scripts against them. I might do: ./nmap --datadir . -p80 -Pn -n -v --open -T4 -sC scanme.nmap.org/24 This took 120 seconds in the run I just did. But almost all of this time is actually from ms-sql-*. If I change -sC to "--script default and not ms-sql-*" to exclude the sql scripts, it takes less than 7 seconds. I'm not sure of the best solution. Options include: o Remove these scripts from "default" o Make mssql.SCANNED_PORTS_ONLY default behavior (so it looks at the port state of common ms-sql ports rather than trying to query all hosts) o Or maybe there are other ways to make it more selective or faster? What do you think? Cheers, Fyodor
Sorry for not getting back to you on this. As I haven't had the time to come up with a better solution, I propose we remove it from default for now. Anyone disagree? //Patrik
