No-ip dyndns update script
2 November, 2013 - 08:36
Hi all,
I need to use dynamic DNS services to control HAH away from home. My router only works with Dyndns.com which is not free anymore and I let my free account expire! DOH.
Anyhow, I have registered with no-ip.com for a free account and written the following script to check and update noip servers if my local IP changes.
I saved the following script as a file (eg noipupdatescript) in /etc directory and chmod a+x it to make it executable.
Then set cron to run it every 15 mins or so like so:
0,15,30,45 * * * * /etc/noipupdatescript
Then if your ip has changed when checked the script will send new address to noip and tweet the response so you can see if it was successful or not.
Cheers
Garry.
heres the script:
#!/usr/bin/lua
-- $Id$
require("string")
require("pl")
require("pl.xml")
require("xap")
require("xap.bsc")
local http=require("socket.http")
local username="username here!"
local pass="pass here!"
local domain="mydomainhere!.no-ip.biz"
if (io.open( "/etc/www/ipaddress.cfg", "r" ) == nil ) then
io.open("/etc/www/ipaddress.cfg", "w"):close()
else
end
local t=pretty.read(file.read("/etc/www/ipaddress.cfg"))
if(t == nil) then t={ipaddress = "0.0.0.0"} end
local xmlstring = http.request("http://ip2country.sourceforge.net/ip2c.php?format=XML")
if(xmlstring == nil) then return end
local d = xml.parse(xmlstring)
data = d:match [[
<lookup>
<ip>$IP</ip>
</lookup>
]]
if data.IP ~= t.ipaddress then
local response = http.request("http://"..username..":"..pass.."@dynupdate.no-ip.com/nic/update?hostname="..domain.."&myip="..data.IP)
t.ipaddress = data.IP
file.write("/etc/www/ipaddress.cfg",pretty.write(t))
xap.init("dbzoo.livebox.Plugboard:Noip","FF00DF99")
bsc.sendText("dbzoo.livebox.Twitter",response)
else
end

I posted a sample no-ip
I posted a sample no-ip updater applet into the HAH source tree.
http://code.google.com/p/livebox-hah/source/browse/trunk/userapps/hah/xa...
Use in conjunction with a HOST and an account setup on http://www.noip.com/
Never really got into the idea of sending lots of messages re where I was and what I was doing ... too much detail! However, your script is a perfect example of something that twitter is really good for.
Thanks for sharing.
