So first off, my suggestion to change the user-agent to firefox was
tongue-in-cheek - I'm sure that was apparent, but I thought I'd better
emphasise it in case it gets misconstrued.
Heh, well I didn't thing it was a terrible idea :). Sometimes you
want to be stealthy and blend into the crowd. But at other times
there is value in being above-board and stating that we're Nmap NSE
and damn proud of it! Right now I think the our http library user
agent is just "Nmap NSE". I think we should at least use a more
standard format. Here is what Yahoo uses:
Mozilla/5.0 (compatible; Yahoo! Slurp/3.0; http://help.yahoo.com/help/us/ysearch/slurp)
We could use something similar:
Mozilla/5.0 (compatible; Nmap Scripting Engine; http://nmap.org/book/nse.html)
Unless someone has a better idea, I'll change it to this for now. If
a bunch of idiots start misunderstanding and thinking it is me trying
to hack their server just because I host the NSE documentation page,
the URL is going away. Or maybe I'll just change it to sco.com or
I agree that it would be nice to have an NSE option argument to set
your own user agent.
For lots of examples: http://www.useragentstring.com/pages/useragentstring.php
Shouldn't the user agent string have a version number in it, too?
And it is really Mozilla/5.0 compatible or are you just trying to make
sure it gives up useful information?
That's a thought. Some websites change their response based on user
agent. This may have unforeseen consequences.
