Yup, you can do that. If you can put CGI on your external web site, you don't even need to figure out what the IP address is. Use a CGI script (hopefully password protected) that looks like: #!/bin/sh cat >../redirect.html <<EOF <HTML><HEAD><TITLE>Redirect</TITLE></HEAD><BODY> <P>Your machine is over <A HREF='http://$REMOTE_ADDR/'>there</A>.</P>; </BODY></HTML> EOF cat <<EOF Content-type: text/plain Ok, it worked. EOF You ppp-linkup script then just needs to do an HTTP GET. Other people mentioned dynamic DNS services. <URL: http://www.dyndns.org/ > will provide this service for free. You use a script to change their dns in ppp-linkup, and then always refer to your machine with a hostname in one of their domains. <mike -- Mike Meyer http://www.mired.org/home/mwm/ Freelance WWW/Unix/FreeBSD consultant, email for rates.
