Re: [NSE] http-slowloris, check if a webserver is prone to the Slowloris DoS attack

There is a limit on the number of open sockets that NSE can have (currently 20)

Just wanted to mention that this value can be changed on the command
line with --max-parallelism.

I read the script and it seems that it cannot handle several targets
because it relies upon the nmap registry to control the threads. The
registry is shared between instances, hence producing undesired
behavior here. A solution can be to use an IP field for each host to
distinguish the entries (like nmap.registry[host.ip]['slowloris']
instead of nmap.registry['slowloris'] for instance). Nevertheless I am
not sure that the nmap registry is well suited to achieve such
inter-thread communications.

Regards.
