Hi All,
I have been looking at OSVDB and I think i can churn out a couple of
plugins...:) I am wondering if there's a standard way of doing it.
1. Do we create a plugin life cycle? e.g.
- Created plugin is accepted,
- verified for correctness and then Commited to the tree?
2. Should we have a plugin directory structure - say Year/Month/*.nasl
or Vendor/Product/*.nasl because at the last count we had 3260 files
under the scripts directory.
3. The plugin id.. Where does it come from?
4. License/Copyrights? I mean should it read "(c) OpenVAS team" or
"This script was written by... for OpenVAS"?
Attached is a simple plugin i've just put together. Please go through
it and comment
This part is obviously wrong
