[ale] "busybox" looping?

[jkinney at localnetsolutions.com (James P. Kinney III)]

Oh. My syntax is, I'm sure, crappy, the idea is there. As long as DHCP
is blank, loop through the process, setting DHCP to NULL if not in good
form.


echo "** Entering bootstrap **"
 while ( ! DHCP ){
 nums=0123456789
 
 echo -n "Enter IP address or DHCP:  "
 read DHCP*
 
 case $DHCP in*
         [$nums]\.[$nums])
                 /sbin/manual_IP 
         ;;
	[Dd][Hh][Cc][Pp])
		echo -n "Starting dhclient: "
                 dhclient && echo "Success." || /sbin/manual_IP
	;;
         *)
                DCHP=""
		echo "I can't start networking with that input" 
		exit
         ;;
 esac
}
