Well, this script will ping yourself every minute, but you don't have to look at it, and it works very nicely.
Been using it myself for a couple of years now, and it works briljantly.
alias keepalive { .ctcp $me ping }
on *:CONNECT:{
.timerkeepalive 0 60 keepalive
}
CTCP *:PING:*:{
if ($nick == $me) {
echo $timestamp 05Connection alive
echo -
halt
}
}
