well i somehow felt someone will be pedantic over it.
its a quick script originally thrown together in a few minutes for personal use and wasn't really
intended to be released, i just thought it may help someone.
besides that this is ment to stop those bruteforce attempts which *all* have more than
enough users without spaces they try. or do you know anyone that does ssh bruteforce by hand?
you may be able to add a bogus ip (wow your l33t), but it wouldnt be of any use so...
instead of beeing a smartass why dont you provide a better solution for the people who are annoyed by
those bruteforce attacks?

i made a small bash script last year to block those bruteforce attempts automatically via the firewall.
In case someone is interested, i released it on our website. Someone may have a use for it :-)
Have a nice day everyone!
That is remarkably shoddy coding from a "security research and
*NEWS FLASH* most platforms allow login names to contain spaces.
$ for ((i=0;i<5;i++));
do ssh -l "j00 ar3 l4m3 220.127.116.11" idiot.running.this.script.com
And i just added an arbitrary address to your firewall, fun!
