Toggle VPN on/off and add/clean vpn routes

gistfile1.applescript

on vpnToggle(vpnName)
	tell application "System Events"
		tell current location of network preferences
			set VPNservice to service vpnName
			set isConnected to connected of current configuration of VPNservice
			if isConnected then
				disconnect VPNservice
				do shell script "./ip-down" with administrator privileges
			else
				do shell script "./ip-up" with administrator privileges
				connect VPNservice
			end if
		end tell
	end tell
	do shell script "dscacheutil -flushcache"
end vpnToggle

请教如果我只是把这两个文件cp到ppp下边，不每次执行ip-up/ip-down有什么影响么？
