This tutorial shows how to use sockets to get info from http://checkip.dyndns.org/index.php and how to use that info to set the ip in mirc correct. This can be usefull if you've a router and a bnc.
;this is a little tutorial about sockets
;
;it's about how to connect to http://checkip.dyndns.org/index.php with mirc, then take your ip out
;
;and use that ip to set $ip
;
;this can be usefull if you've a router and a bnc, depending on your mirc settings, mirc will normally
;make $ip your bnc serverip, or your local ip, like 192.168.0.2
;
;
;on connect event, with timer, so if you connect to 3 different servers on start up, it'll only be triggered once :)
on *:connect:{ .timermyip 1 5 myip }
alias myip {
;if the socket already is open, close it, you can only have one connection with the same name at the same time
if ($sock(myip)) { sockclose myip }
;to open a socket with name myip to address checkip.dyndns.org on port 80
sockopen myip checkip.dyndns.org 80
}
;this event is triggered on the moment the sockets is opened
on *:sockopen:myip:{
;to tell the server which file you want to receive
sockwrite -n $sockname GET /index.php HTTP/1.0
sockwrite -n $sockname Host: checkip.dyndns.org
;this is only needed for a few websites, but it's just more complete to have it ;)
sockwrite -n $sockname user-agent: Mozilla/??
sockwrite -n $sockname Connection: Keep-Alive
sockwrite -n $sockname $crlf
}
on 1:sockread:myip:{
;same way as in mirc helpfile with the :nextread
if ($sockerr > 0) return
:nextread
sockread %temp
if ($sockbr == 0) return
;to check if we got the right line, it's pretty easy for this file, but usually more complicated,
;use $gettok or variables to get the right line.
if (<html> isin %temp) {
;%temp will contain something like:
;<html><head><title>Current IP Check</title></head><body>Current IP Address: 217.20.116.184</body></html>
;an easy way to 'strip' it is with $remove
var %z = $remove(%temp,<html><head><title>Current IP Check</title></head><body>Current IP Address:,</body></html>)
;scon -a is to send a command to all servers mirc is connected to
scon -a localinfo $chr(10) %z
scon -a echo 4 -s ip is set to $ip
}
goto nextread
}
;If your knowledge about sockets is still $null or just not enough yet ;), maybe read this tutorial:
