About ez-ipupdate
Ez-ipupdate is a small utility for updating your host name IP for any of the dynamic DNS services 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
- 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 following:
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 sure to add the according service-type. See above for 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. Therefore add to /etc/shorewall/rules
HTTP/ACCEPT fw net
Don't forget to save your configuration with lrcfg -> s!
