(free dynamic DNS service that relies on open standards) Configuration Predefined DD-WRT provides a set of predefined configurations for the most common DDNS services. After choosing from one of the predefined DDNS services, you have to provide the 'User Name' and the 'Password' for the account of your DDNS service. In the 'Host Name' field, you have to enter the fully qualified name of your dynamic domain (e.g. Multiple DDNS host names If you have multiple host names registered at your DDNS service, you can enter them in the 'Host Name' field using the '-a' option. Example: You want to update the IP address for myhostname1.example.org, myhostname2.example.org and myhostname3.example.org; in this case, you have to enter in the 'Host Name' field the following string: 'myhostname1.example.org -a myhostname2.example.org -a myhostname3.example.org'. (Note: no '-a' for the first host name.) Custom (URL Updates) With url updates, the client program usually submits a request using the hypertext transport protocal (HTTP) to a DDNS Server. The request may contain your requested hostname (your dynamic domain name) and/or your IP address.
The server then asks for the username and password. The client program returns the information to authorize itself, and the update is completed with the server request response to verify the result. When your DDNS Service provider uses URL updates, you need to know the url which the client program requests. An example of such a url is: The URL is divided into parts, the parts should be simple to divide. Protocol Usually appears first and is followed by '://' Location Usually after protocol, this can be an IP address or a domain name Port (optional) Sometimes appears after location, only appears after a colon. URI The last part of the URL, which can be subdivided.
It normally appears after the location and port. The URI can be subdivided even futher. Most of the URI is optional. URI Location Everything before the '?' URI Parameters Everything after the '?' And before the '#'.
There can be many parameters. Many times, as in the above example is it specified in the 'name=value' form. And commonly when more than one value needs to be specified, it is divided with '&' so 'name1=value1&name2=value2&name3=value3' can be used to specify three parameters. URI Link Everything after the '#', used to specify a specific point in a page. The example request above is: Protocol http Location example.com Port Not specified URI /dyndns/update?hostname=hostname.example.org URI Location /dyndns/update URI Paramater 'hostname' hostname.example.org To confirm that you have the correct URL and can manually update your IP by using your web browser.
When prompted, input your registered username and password. If you aren't registered, register one and setup (add) your dynamic domain name first. Once you have the information, you should be able to set it up using DD-WRT.
Login to the Web GUI, Set DDNS under 'Setup' to 'custom'. If the URL paramaters have 'hostname' use '[email protected]' for DNS System. Otherwise use 'custom@httpsvrbasicauth'. Enter 'Username' and 'Password' with your registered username and password of your DDNS service provider. Fill in your hostname in 'Host Name'.
Complete options in 'Additional DDNS Options' textarea. Save Changes and Reboot Router Additional DDNS Options For the custom DDNS to work properly we must specify options so that the program knows what to do. Specify the Server Name option, this is Location and perhaps the port (if specified) of the URL. Specify Server URL Option.
If you used the '[email protected]' as 'DNS System' you need to specify the Server URL option as just the URI Location; otherwise you need to specify the entire URI. Using the example above, the Additional DDNS Options should be: ' -dyndnsservername example.com -dyndnsserverurl /dyndns/update' If this isn't working, try pinging checkip.dyndns.org. You may have to use the 'ipservername' option if you are unable to recieve a response.
The IP address option is used to specify an alternate source to get your IP. Many websites have options to view your IP Address. For the update to work properly, the IP Address check must be be done on the server side (no javascript/vbscript) and your ip address must be the first address on the page. You may need to confirm this by using 'View Source' in your browser. Example: Dividing this URL is similar to dividing the one above: Protocol http Location www.dnsstuff.com Port Not specified URI /tools/my-ip-address.ch URI Location /tools/my-ip-address.ch The 'ipservername' option uses the Location and the URI. If there is not a URI, use '/' The 'ipservername' string using the server above should be: '-ipservername www.dnsstuff.com /tools/my-ip-address.ch' Note the space beteen the Location and URI.
If you have multiple dyndns domains under the same account and need to update them together, you can add one or more '-a' options to do so. Ie, '-a SECONDHOSTNAME.example.com'. This only works if the domains are under the same provider and account. So, finally, the additional options should be complete and will work in general cases. Examples dnsExit.com is a domain registrar that provides DDNS.

You will have to login every 30 days to keep your account alive. Some guys in the created some scripts to manage the login automaticly. Use this scripts (wget version) as custom script with cron. NameCheap is a domain registrar that includes free dynamic dns with the host registration.
Under $10/year. NameCheap doesn't use normal http auth for updating, so you have to include your domain and password in the URL.
Anything between brackets should be changed to your appropriate information. Do not put anything after the &host= in the URL option! DDNS Service: Custom DYNDNS Server: dynamicdns.park-your-domain.com Username: (Any jibberish can go here.) Password: Your NameCheap-defined Dynamic DNS password Host Name: Your subdomain ('www' for the standard, or '@' for no subdomain) URL: /update?domain=your domain&password=your password&host= Note: If you would like to update the IP address for more than one subdomain, separate each subdomain in the Host Name box with an '-a' argument. For instance: Host Name: www -a webmail -a waycoolstuff would cause www.your domain, webmail.your domain, and waycoolstuff.your domain to be updated to the same IP address.
Updated Dec 1, 2009, after the instructions provided at electronox.net (see link below) worked. 22:30, 1 December 2009 (CET) (Note: I think these instructions may be old. It doesn't cost anything now. I registered my domain at godaddy and was able to change the nameservers to those from namecheap. Also, for ddns, try using your domain name in the username field and the password generated by namecheap (specifically for ddns -.not. your login password!) in the password field.
And it doesn't seem to need the password in the url as part of the get request (which is kind of stupid, sending it in the clear.). This worked for me. See -wikiterra Aug 8, 2009) (Follow up: Leaving the password out of url does not seem to work as that site suggests, otherwise it works correctly. On another note, does anyone know how to force ssl? Namecheap's dyndns server works with https, but the interface in dd-wrt doesn't seem to have that option, at least not in an obvious way.wikiterra March 30, 2010) CHANGEIP.COM The information below is how to configure your router to update dynamic dns hostnames:. substitute your account setting for those in quotes DDNS Service Custom DYNDNS Server nic.changeip.com User name 'Your ChangeIP.com username' Password 'Your ChangeIP.com password' Hostname 'Your DynDNS hostname' or '.1' for Group #1 URL /nic/update?system=dyndns&hostname= Additional DDNS Options -ipservername ip.changeip.com / Regfish is a domain registrar that provides dyndns updates.

Additionally dynamic DNS works on all your own domain names registered on Nubem. Please note that in this sample configuration we suppose that you Nubem username is peterg and that your pasword is letmein.
The associated free ddns hostname is peterg.mynubem.com. Remember to replace the example values with your own ones.

A more detailed configuration with graphical screen shoots is available at.
Is provided as well. I gave up on trying to setup my freedns.afraid.org setup and just set a cron script at startup to use freedns' wget method of updating my dns every 5 minutes on the router.
If this does not work for you, some variation on this theme might: echo './5. root /usr/bin/wget -O - /dev/null 2&1' /tmp/crontab NOTE: In the above, the XXXXXX is an id number provided by freedns.afraid.org Note2: This shouldn't be necessary and causes more traffic than is needed. Please read my entry in the afraid.org section above. It does work. Note3: FYI the busybox wget command on your version of dd-wrt may not work with https, so you may have to use the unsecure http protocol to update DNS via URL.
Secure DDNS Updates Over HTTPS/SSL As of DD-WRT v24, the inadyn client embedded in most DD-WRT releases does not support HTTPS/SSL updates. This means your username and password are sent in clear text over the Internet. Advanced users can use a simple script which utilizes curl to make these updates in a more secure manner until a newer version of inadyn which supports HTTPS can be included. First, enable JFFS under AdministrationManagement, or using the instructions available.
Run 'mkdir /jffs/opt' from your router's command line. Run 'mount -o bind /jffs/opt /opt'. Run 'opkg update' and then 'opkg install curl', verify that curl is installed in /opt/usr/bin. Download the CA bundle for curl - 'cd /opt/usr/bin' then 'wget. Get the example script from the.
Copy the script into /opt/usr/bin/dyndns.sh. Edit the settings section of dyndns.sh to match your DynDNS provider and save. Run 'chmod 755 /opt/usr/bin/dyndns.sh' to make the script executable. Now just add the following commands to your startup commands in AdministrationCommands. mount -o bind /jffs/opt /opt.
sleep 5. /opt/usr/bin/dyndns.sh This script will enter an endless loop and check/update your IP in the interval you specify in the settings section. Curl is able to make these updates securely using HTTPS. Debugging your configuration Internaly, DD-WRT uses inadyn and creates in the directory /tmp/ddns a configuration file from your settings in the web form. To check whether the expected configuration file is created from your settings in the web form, you can inspect this file as follows:.
ssh or telnet to the router. navigate to /tmp/ddns: cd /tmp/ddns. inspect file inadyn.conf: cat /tmp/ddns/inadyn.conf.
the inadyn cache file in DD-WRT is located /tmp/ddns/inadynip.cache If you are not familiar with the format of the inadyn.conf file, you can just call /usr/sbin/inadyn from the command line and the allowed parameters are shown. Put '-verbose 5' in the additional ddns options to get some helpful information. Password conventions Have a look at the characters you use in your password. If there is a '#' in it, it won´t work because linux parses everything in the config file, that´s behind a '#' as a comment!
