Re: NSE Socket Operation on a non-socket

[Joao Correa <joao () livewire com br>]

I've tried to reproduce the errors using the commands David mentioned.
I also used the common ips file provided by Patrick. The only error
I've found was:

./nselib/stdnse.lua:61: bad argument #4 to 'format' (string expected, got table)
stack traceback:
        [C]: in function 'format'
        ./nselib/stdnse.lua:61: in function 'print_debug'
        ./scripts\html-title.nse:180: in function 'is_vhost'
        ./scripts\html-title.nse:114: in function 'rule'
        ./scripts\html-title.nse:156: in function 'redirect_ok'
        ./scripts\html-title.nse:55: in function <./scripts\html-title.nse:45>
        (tail call): ?

This error happens due to a return from dns.query(). I'm not very
familiar with dns.lua, so I'm not able to point the 'cause of the
problem. Also, this problem only happens while running on windows XP
SP2, and not on linux. Anyway, both errors does not seem to be
connected...

While running only html-title.nse, the error only happens to a
percentage of the tests, just like David mentioned.
