while [ $n -le $1 ]
# this part I don't understand

tinydyndns-conf(8)					      System Manager's Manual						tinydyndns-conf(8)

NAME

       tinydyndns-conf - sets up a pop-before-dyndns service

SYNOPSIS

       tinydyndns-conf acct logacct dir myip mydomain

DESCRIPTION

       tinydyndns-conf	creates a service directory dir that runs tinydns(8), and a service directory dir/pop that runs a pop3 service and updates
       tinydns' database after a successful login.

       You can run the services under svscan(8) or runsvdir(8) by creating symbolic links in the /service directory:

	 ln -s dir /service/dir
	 ln -s dir/pop /service/dir-pop

       The service will start within five seconds, and will be restarted upon reboot.  You can use svc(8) to control the service.

       tinydyndns-conf runs

       tinydns-conf acct logacct dir myip

       to set up a DNS publication service.

       tinydyndns-conf modifies dir/root/Makefile to not run tinydns-data(8) upon normal request.

       tinydyndns-conf arranges for tcpserver(1) to listen on TCP port 110, and to start pop3front-auth(8), cvm-pwfile(8), and after a	successful
       login tinydyndns-update(8), and pop3front-maildir(8) upon connections.

       tinydyndns-conf creates a setpasswd script and a default passwd database in dir/pop for the use with cvm-pwfile(8).

       tinydyndns-update(8), tinydyndns-data(8), tinydns(8), tcpserver(1), pop3front-auth(8), cvm-pwfile(8), pop3front-maildir(8)
