on *:join:#:{

else { mode $chan +v $nick }
}


Is wrong ... but I don't see where it goes wrong ... the syntax is correct I think ...

If a user joins, and his host is in the badhosts.txt he should be kicked ... that's what I'm trying to do

on *:join:#:{
if ( $address($nick,4) == $read("badhosts.txt") ) { kick $chan $nick Bad Host }
else { mode $chan +v $nick }
}

works fine

" " was needed ...

of course you can do better a ban ... if autorejoins is on your bot starts flipping

$read(badhosts.txt) reads a random line from that file..

So it not checks every line ... hmz

on *:join:#:{
if ( $address($nick,4) == $read(badhosts.txt,s,$address($nick,4)) ) { mode $chan +b $address($nick,4) | kick $chan $nick }
else { mode $chan +v $nick }
}

But now it do nothing

if ($read(badhosts.txt,w,$address($nick,4)) ) { mode $chan +b $address($nick,4) | kick $chan $nick }

I'm sure I've tried that before, and you need to make the address into a wildcard string, with *'s at both ends of the address
*!*@*.host*

so you would use:

if ($read(badhosts.txt,w,$+($address($nick,4),*)) ) { mode $chan +b $address($nick,4) | kick $chan $nick }

Don't know if it is right, but something I'm sur eI remember from past scripting...
