About ez-ipupdate
Ez-ipupdate is a small utility for updating your host name IP for any of the dynamic DNS service offered at:
http://www.ez-ip.net
http://www.justlinux.com
http://www.dhs.org
http://www.dyndns.org
http://www.ods.org
http://gnudip.cheapnet.net (GNUDip)
http://www.dyn.ca (GNUDip)
http://www.tzo.com
http://www.easydns.com
http://www.dyns.cx
http://www.hn.org
http://www.zoneedit.com
The key features are: support for multiple service types and updating your IP address if it changes.
To install the ezipupd.lrp package, edit leaf.cfg file and add ezipupd.lrp in the list of packages to be loaded at boot.
Configuring ez-ipupdate
You can edit the ez-ipupdate configuration file through the package configuration menu:
ez-ipupd configuration files 1) ez-ipupdate configuration file q) quit --------------------------------------------------------------------------- Selection:
The parameters allowed in the configuration file are the followings:
address usage: address=[ip address] cache-file usage: cache-file=[cache file] cloak-title usage: cloak-title=[title] daemon usage: daemon=[command] execute usage: execute=[shell command] debug usage: debug foreground usage: foreground pid-file usage: pid-file=[file] host usage: host=[host] interface usage: interface=[interface] mx usage: mx=[mail exchanger] max-interval usage: max-interval=[number of seconds between updates] notify-email usage: notify-email=[address to email if bad things happen] offline usage: offline retrys usage: retrys=[number of trys] server usage: server=[server name] service-type usage: service-type=[service type] timeout usage: timeout=[sec.millisec] resolv-period usage: resolv-period=[time between failed resolve attempts] period usage: period=[time between update attempts] url usage: url=[url] user usage: user=[user name][:password] run-as-user usage: run-as-user=[user] run-as-euser usage: run-as-euser=[user] (this is not secure) wildcard usage: wildcard quiet usage: quiet connection-type usage: connection-type=[connection type] request usage: request=[request uri] partner usage: partner=[easydns partner]
Here is how it could look like:
service-type=zoneedit user=myname:mypassword interface=eth0 host=mydomain.com #notify-email=john.doe@mydomain.com # other options: #address=<ip address> #cache-file=/tmp/ez-ipup #daemon #debug #foreground #host=<host> #interface=<interface> #mx=<mail exchanger> #retrys=<number of trys> #run-as-user=<user> #run-as-euser=<user> #server=<server name> #timeout=<sec.millisec> #max-interval=
The four most important entries for a typical LEAF Bering-uClibc installation will be explained below:
service-type - make shure to add the according service-type. See above the
list of available services.
user - here you have to provide your username and password for the choosen
service seperated by a colon.
interface - this defines your interface to the internet - the one which is
changing from time to time and whose ip should be changed at your dynamic
DNS service (usually eth0 or ppp0)
host - the host(s) you like to have been updated. It is possible to update
more than one host for a service-type. To allow that, add all your hosts
separated by a comma.
Please note: The options cache-file and daemon aren't needed. notify-email doesn't work today.
Using ez-ipupdate
Through dhclient exit-hook script:
reload_all() { /sbin/shorewall restart echo "Starting ez-ipupd from dhclient ..." /etc/init.d/ez-ipupd start }
Through ppp's /etc/ppp/ip-up script: All you need is to add the command /etc/init.d/ez-ipupd -start to /etc/ppp/ip-up.
# Main Script starts here # /etc/init.d/ez-ipupd restart run-parts /etc/ppp/ip-up.d [ -x /bin/beep ] && /bin/beep -f 600 -n -f 900 -n -f1200 -n -f1800 # last line
Configure shorewall
You need to add a rule to allow accessing port 80 from your firewall on the net zone to make ez-ipupdate work. Therefor add to /etc/shorewall/rules
HTTP(ACCEPT) fw net
Don't forget to save your configuration with lrcfg -> s!
