[NSE] Fix for auth-owners.nse

[Richard Sammet <richard.sammet () googlemail com>]

Hi Guys,

I noticed that the script auth-owners.nse is not working with some
ident daemons. After a few seconds of debugging I identified the
problem:

 owner = string.match(owner, "USERID : .+ : (.+)\n", 1)

This would only match if the format of the reply exactly matches with
all the whitespaces. E.g. (gidentd):

22, 45200 : USERID : UNIX : root

Most of the identd's I tested this script against are replying with
(e.g. oidentd, openbsd-identd, ...):

22,45200:USERID:UNIX:root

And in this case the script will not report anything.

I wrote a small patch which fixes that issue and makes it working with
every format I've seen so far... (attached)


Greetings,
Richard
