[julia-users] RandIP A random IP generator for Large scale network mapping.

[Jacob Yates]

I've been working on porting a script I wrote in python to julia and have 
been having some issues with the script freezing.

So pretty much all this script does is generate a random IP address and 
checks to see if its valid(the Python version will give http error codes) 
then logs the results for further analysis.

function gen_ip()
        ip = Any[]
        for i in rand(1:255, 4)
                push!(ip, i)
        end
        global ipaddr = join(ip, ".")
end

function test_ip()
        gen_ip()
        println("Testing IP: ", ipaddr)
        global socket = connect(ipaddr, 80)
end

function timer()
        sleep(5)
        close(socket)
end

try
        while true
                @async test_ip()
                @async timer()
                timer()
        end
catch err
        println("Simple Error:\n", err, "\n")
        println("Detailed Error: ", error(), "\n")
        println("Bactrace: ", backtrace())
        exit()
end
