Simply put, using this service gives a name to your IP. So if you're hosting something on your line, people would not have to bother typing your IP. They can just type in your domain name! It also helps when your IP changes. Users won't need to discover what your new IP is, they can simply type your domain name. This guide will help you configure your DDNS service, so that your router auto-updates your IP to your DDNS provider. The simplest method possible would be through LuCI (the default webUI for OpenWrt). OpenWrt uses ddns-scripts which are Bourne shell scripts. There are other scripts and programs available in the web, also some DDNS providers offer their own programs. All of them are currently not ported and tested on OpenWrt. Requirements First of all, you'll need to pick and register a DNS name with a compatible DynamicDNS service provider. For a list of DDNS providers, see: https://www.google.de/search?q=dynamic+dns+provider+list http://www.opendirectoryproject.org/Computers/Internet/Protocols/DNS/Service_Providers/Dynamic_DNS https://dnslookup.me/dynamic-dns/ ddns-scripts support the following Dynamic DNS service provider out of the box: 3322.org afraid.org 6) changeip.com cloudflare.com 2) 5) 6) core-networks.de 6) ddnss.de 6) dhis.org 6) dnsdynamic.org dnsexit.com dnshome.de 6) dnsmax.com dnsomatic.com dnspark.com do.de 6) dtdns.com duckdns.org 6) duiadns.net 6) dy.fi dyndns.org 6) (dyn.com) dyndnss.net dyns.net dynsip.org dynu.com dynv6.com 6) easydns.com editdns.net goip.de 6) google.com 5) 6) he.net 6) joker.com loopia.se 6) (loopia.com) mydns.jp 6) myonlineportal.net 6) mythic-beasts.com 6) namecheap.com nettica.com no-ip.com 1) (noip.com) no-ip.pl 6) nsupdate.info 6) nubem.com ovh.com regfish.de 6) schokokeks.org selfhost.de sitelutions.com spdyn.de 6) (spdns.de) strato.com system-ns.com thatip.com twodns.de variomedia.de 6) zerigo.com 6) zoneedit.com 5) zzzz.io 5) 6) BIND nsupdate 3) 4) 6) 1) requires additional package ddns-scripts_no-ip_com to be installed. 2) needs additional package ddns-scripts_cloudflare to be installed. 3) directly updates a PowerDNS (or maybe bind server) via nsupdate. 4) needs additional package ddns-scripts_nsupdate and bind-client to be installed. 5) SSL support required. 6) support IPv6 If you have picked a DDNS service provider and create your host/domain name you need to note additional your username and password. Now you need to decide if you want to use secure communication with your DDNS provider or not. Some provider require secure (HTTPS) communication. Read their help pages for details and also read provider specific informations below.

OpenWrt Forum Github-OpenWrt-Packages for ddns-scripts Github-OpenWrt-LuCI for luci-app-ddns A full list of supported settings (some not supported by LuCI webUI): UCI documentation → Dynamic DNS Client configuration The source code is available at GitHub: CC 15.05 ddns-scripts_2.4.3-1 luci-app-ddns_2.2.4-1 trunk ddns-scripts luci-app-ddns Installation using LuCI Login into your router through your browser. From the menu select 'System' → 'Software' Press button [Update Lists] to update internal lists of available packages. Filter for ddns and install luci-app-ddns package. Installing the package luci-app-ddns will automatically install the package ddns-scripts. You might need to install provider specific packages ddns-scripts_xxxxx and LuCI language packages luci-i18n-ddns-xx. After luci-app-ddns (and other packages) are installed, just press any other menu entry on the LuCI webUI, and the page will refresh itself and it will appear in the menu under 'Services' → 'Dynamic DNS'. via console To install ddns-scripts use the OPKG Package Manager You might need to install provider specific packages ddns-scripts_xxxxx opkg update opkg install ddns-scripts opkg install ddns-scripts_xxxxx SSL support By default ddns-scripts uses BusyBox built-in 'wget' for DDNS updates over http, which does not support https (SSL). To perform DDNS updates over https (SSL), you will need to install the 'wget' or 'curl' package, and add the appropriate root certificate for your ddns provider. If both 'wget' and 'curl' are installed you can configure which one to prefer. Default is 'wget'. You can install either via LuCI (from the menu select 'System' → 'Software') and search for 'wget' or 'curl' or install via console using following commands: opkg update opkg install wget # normally you only need opkg install curl # either wget or curl opkg install ca-certificates If you, also for other software, need all certificates in one file or you want to update CA certificates regulary, then do NOT install 'ca-certificates' package. 'ca-certificate' package is not always backported to older OpenWrt versions. Install latest CA certificates (in one file) using console: mkdir -p -m0755 /etc/ssl/certs curl -o /etc/ssl/certs/ca-certificates.crt http://curl.haxx.se/ca/cacert.pem # using curl wget --no-check-certificate -O /etc/ssl/certs/ca-certificates.crt http://curl.haxx.se/ca/cacert.pem # using wget Since OpenWrt 17.01.7 (and earlier?) Wget works with ca-certificates package, but curl does not. Instead install ca-bundle, if you wish to use curl (but not wget). other functions This does not belong to the Installation section. Move it to where it better fits the context. — tmomas 2017/04/24 01:05 ddns-scripts support other special communication functions to be used: Run once (useful for usage with crond) Set proxy with/without authenfication for http/https requests Set DNS server to use other than system default Binding to specific network if wget or to specific interface if curl installed. Force the usage of either IPv4 or IPv6 communication only. Require either wget or curl AND bind-host ! DNS requests via TCP. Require either wget or curl AND bind-host ! Configuration Basics ddns-scripts are designed to update one host per configuration/section. To update multiple hosts or providers or IPv4 and IPv6 for the same host you need to define separate configurations/sections. Some providers offer to update multiple host within one update request. A possible solution for this option is to use –custom– service name settings. Have a look at Provider specifics. The main settings you need to set are (all other normally work fine with the defaults): Service name the DDNS service provider to use Host/Domain your FQDN you want to update (used by ddns-scripts using nslookup to check if update has happen) Username username or other parameter to use as username (send urlencoded) Password password or other parameter to use as password (send urlencoded) including BB 14.07 Ensure this password does not have “$1” or $ with any number following in it, as this breaks the script. Interface network name (i.e. wan, wan6) used by OpenWrt hotplug event system to start ddns-scripts since DD (trunk) the following main settings need to be set: Service name the DDNS service provider to use Lookup Host ONE of your defined FQDN you want to update (used by ddns-scripts using nslookup to check if update has happen) Host/Domain mostly same as 'Lookup Host', but now can also be used as “normal” parameter. i.e. as list of hosts to be updated Username username or other parameter to use as username (send urlencoded) Password password or other parameter to use as password (send urlencoded) Interface network name (i.e. wan, wan6) used by OpenWrt hotplug event system to start ddns-scripts After fresh installation a configuration/section 'myddns' and 'myddns_ipv4' and 'myddns_ipv6' exists ready to be modified for your needs. You could delete them and define your own. Please heed the following important hints: It is NOT allowed to use dash-sign “-” inside configuration/section names. A full list of supported settings (some not supported by LuCI webUI) you will find in UCI documentation! Always keep in mind the Provider specific settings if there are any! Don't forget to enable your configuration/section! You need minimum one enabled configuration/section for ddns service to start! You need to enable ddns service to enable updates being sent on reboot and hotplug events! Although described elsewhere, it is not recommended to change the files '/usr/lib/ddns/services' or '/usr/lib/ddns/services_ipv6' because they will be overwritten during system and package updates! using LuCI Login into your router through your browser. From the menu select 'Services' → 'Dynamic DNS'. Navigate to the configuration/section you like to change. Modify the fields you need to change. Don't forget to check the 'Enabled' option! Click [Save & Apply] button to save changes. To add a new configuration/section: Type the new name into the text entry box at the bottom of the page next to [Add] button. Do not use a dash character “-” in configuration/section name! Click [Add] button. Modify the fields you need to change. Don't forget to check the 'Enabled' option! Click [Save & Apply] button to save changes. 'Username' and 'Password' fields are required fields. If your provider does not require one or both of them, simply put in a character of your choice. You need to enable ddns service! From the menu select 'System' → 'Startup'. Set ddns service to enabled. SSL Support Options to configure HTTPS communication are only available if wget or curl package is installed. (See Hints if shown.) Check 'Use HTTP Secure' option. Additional field 'Path to CA-Certificate' is shown with it's default setting. If you have installed ca-certificates package leave the shown default! (/etc/ssl/certs) If you have installed CA certificates in one file from above set the value to: /etc/ssl/certs/ca-certificates.crt If you like to use other certificate you need to set here the full path to the certificate including file name. (/path/to/file.crt) If your certificates are stored in a different path, set here the path where your certificates are located. (/path/to/files) Click [Save & Apply] button to save changes. Custom Service If you want to use a DDNS provider currently not listed or you want to update multiple hosts within one configuration/section then you should do the following: Choose '–custom–' as service. Additional field 'Custom update-URL' is shown. Fill in the URL you like to use. Please read URL syntax description below. Also have a look at Provider specifics. Click [Save & Apply] button to save changes. If you found a DDNS provider not listed or with additional IPv6 support or with changed update URL please open an issue at Github-OpenWrt-Packages so it can be included with the next release. via console The easiest way to configure ddns-scripts via console is to edit the file /etc/config/ddns directly using build-in vi editor or any other editor you prefer. Other editors as vi needs to be installed separately. A configuration/section looks like: config 'service' 'myddns' option 'service_name' 'example.org' option 'enabled' '1' option 'domain' 'yourhost.example.org' option 'username' 'your_username' option 'password' 'your_password' option 'interface' 'wan' option 'ip_source' 'network' option 'ip_network' 'wan' Alternatively you can use UCI command line interface. Example input: uci set ddns.myddns.service_name="ddnsprovider.com" # only use names listed in /usr/lib/ddns/services # or /usr/lib/ddns/services_ipv6 (since CC 15.05) uci set ddns.myddns.domain="host.yourdomain.net" uci set ddns.myddns.username="your_user_name" uci set ddns.myddns.password="p@ssw0rd" uci set ddns.myddns.interface="wan" # network interface that should start this configuration/section uci set ddns.myddns.enabled="1" uci commit ddns # don't forget this, otherwise data not written to configuration file ddns.myddns.enabled=“1” means: 'ddns' is the configuration file to change (here /etc/config/ddns) 'myddns' is the configuration/section to change 'enabled' is the option to set/change behind the equal-sign is the value to set. Set single- or double-quotes around the value and no space or whitespace around the equal-sign. Example to create/add a new configuration/section “newddns”: uci set ddns.newddns="service" uci set ddns.newddns.service_name="ddnsprovider.com" # only use names listed in /usr/lib/ddns/services # or /usr/lib/ddns/services_ipv6 (since CC 15.05) uci set ddns.newddns.domain="host.yourdomain.net" uci set ddns.newddns.username="your_user_name" uci set ddns.newddns.password="p@ssw0rd" uci set ddns.newddns.interface="wan" # network interface that should start this configuration/section uci set ddns.newddns.enabled="1" uci commit ddns # don't forget this, otherwise data not written to configuration file You need to enable ddns service by: /etc/init.d/ddns enable SSL Support You need to add the following entries to the desired section in '/etc/config/ddns' file: using 'ca-certificates' package: config 'service' 'myddns' ... option 'use_https' '1' option 'cacert' '/etc/ssl/certs' using single file (ie. as descriped above): config 'service' 'myddns' ... option 'use_https' '1' option 'cacert' '/etc/ssl/certs/ca-certificates.crt' # option 'cacert' '/full/path/to/file.crt' Above options can also be set via LuCI webUI. The options are only shown if 'wget' or 'curl' package is installed! Custom Service Following changes need to be done if you use a DDNS provider currently not listed or to update multiple hosts within one configuration/section. Edit '/etc/config/ddns' config 'service' 'myddns' ... # option 'service_name' 'example.org' # comment out "#" or delete option 'update_url' 'http://your.update.url...[USERNAME]...[PASSWORD]...[DOMAIN]...[IP]' or use UCI command line interface uci delete ddns.myddns.service_name uci set ddns.myddns.update_url="http://your.update.url...[USERNAME]...[PASSWORD]...[DOMAIN]...[IP]" uci commit ddns # don't forget this, otherwise data not written to configuration file URL Syntax It's not needful to set 'https://'. If SSL support is activated 'http://' is replaced automatically. The entries [USERNAME] [PASSWORD] [DOMAIN] [IP] are replaced by ddns-scripts just before update. [USERNAME] is replaced by content of 'option username' from configuration file. [PASSWORD] is replaced by content of 'option password' from configuration file. [DOMAIN] is replaced by content of 'option domain' from configuration file. [IP] is replaced by the current IP address of your OpenWrt system. carefully set 'option domain' in your configuration. This option is also used to detect if the update was successfully done. This entry is the DNS name your OpenWrt system will be reachable from the internet. Have a look at Provider specifics for samples. If you found a DDNS provider not listed or with additional IPv6 support or with changed update URL please open an issue at Github-OpenWrt-Packages so it can be included with the next release.

You need to enable ddns service! Basics Normally no user actions are required because ddns-scripts starts when hotplug ifup event happens. This will happen automatically at system startup when the named interface comes up. Event ifup also happens when a dialup network comes up. ddns-scripts regularly check if there is a difference between your IP address at DNS and your interface. If different an update request is sent to DDNS provider. Whenever you [Save & Apply] an Enabled configuration/section from LuCI webUI the corresponding script is automatically restarted. If you modify '/etc/config/ddns' configuration file from console, you need to restart ddns-scripts (see below) to apply changes. To check if ddns-scripts are running you could check inside LuCI via 'Status' → 'Processes' or via console running ps -w | grep dynami[c] You should find something like '… /bin/sh /usr/lib/ddns/dynamic_dns_updater.sh myddns 0' for every configuration/section you configured and enabled, where myddns shows your configuration/section name. Inside LuCI also exists a section 'Dynamic DNS' at 'Status' → 'Overview' page showing the current status of your DDNS configurations. Run manually using LuCI To check running ddns-scripts processes from the menu goto 'Status' → 'Processes'. Look for something like '/bin/sh /usr/lib/ddns/dynamic_dns_updater.sh myddns 0'. To stop a desired process press the [Terminate] or [Kill] button. The process should remove from the list. You can enable/disable and start/stop ddns-scripts from 'System' → 'Startup' menu. Look for service 'ddns' and press the button for the desired action. You can additionally enable/disable and start/stop individual configuration/section from 'Overview'-page at 'Services' → 'Dynamic DNS'. via console From console command line you could create an 'ifup' hotplug event for the desired network interface. This will start all enabled ddns configurations/sections monitoring this interface. Keep in mind that also other service processes (i.e. firewall) might be (re-)started via 'ifup' hotplug event! For INTERFACE, type the specified ddns-scripts interface name (the interface name from /etc/config/network, usually 'wan') ACTION=ifup INTERFACE=wan /sbin/hotplug-call iface To start only one ddns-scripts configuration/section (here 'myddns'): /usr/lib/ddns/dynamic_dns_updater.sh myddns 0 & To start all ddns-scripts configurations configured for one interface (the interface name from /etc/config/network, usually 'wan'): sh . /usr/lib/ddns/dynamic_dns_functions.sh # note the leading period followed by a space start_daemon_for_all_ddns_sections "wan" exit To stop one configuration/section you need to list running ddns processes with: ps -w | grep dynami[c] you will get something like: 2493 root 1440 R {dynamic_dns_upd} /bin/sh /usr/lib/ddns/dynamic_dns_updater.sh myddns_1 0 2494 root 1440 R {dynamic_dns_upd} /bin/sh /usr/lib/ddns/dynamic_dns_updater.sh myddns_2 0 now you need to kill every running process: kill 2493 # to kill one process kill 2493 2494 # to kill multiple processes To stop all running processes at once ('killall' might not be available on all systems): killall dynamic_dns_updater.sh # if killall is available ps | grep dynami[c] | awk '{print $1}' | xargs kill # or if not available Since BB 14.07 you could enable/disable and start/stop/restart all enabled ddns configuration/section like every other service: /etc/init.d/ddns disable /etc/init.d/ddns enable /etc/init.d/ddns start /etc/init.d/ddns stop /etc/init.d/ddns restart using scheduler Each configuration/section of ddns-scripts can be configured to run once including retry on error so it is guaranteed that the update is sent to the provider. To configure your configuration/section to run once you need to set 'option force_interval' to '0'. Setting of 'option force_unit' is ignored. Inside LuCI set 'Force Interval' in [Timer Settings]-tab of your desired configuration or edit '/etc/config/ddns' on console. config 'service' 'myddns' ... option 'force_interval' '0' If you set ddns service to enable then all configurations/sections are started during interface 'ifup'. The configuration/section configured to run once will stop after successful update. To guarantee that your configurations only run once not looking for an interface event you need to disable ddns service. To start your configuration via build in crond use the following entry as command inside crontab configuration (replace 'myddns' with the name of your configuration/section): /usr/lib/ddns/dynamic_dns_updater.sh myddns 0 & Monitoring Syslog The 'option use_syslog' (also in LuCI) allows to define the level of events logged to syslog: Value Reporting 0 disable 1 info, notice, warning, errors 2 notice, warning, errors 3 warning, errors 4 errors Critical errors forcing ddns-scripts to break (stop) are always logged to syslog. Logfile ddns-scripts have built-in logfile support. Logfiles are automatically truncated to a settable number of lines (default 250 lines). Inside LuCI you could enable logfile in [Advanced Settings]-tab of desired configuration/section. From console you need to edit '/etc/config/ddns' file: config 'service' 'myddns' ... option 'use_logfile' '1' In case your device has enough built in memory or if you are using Extroot, you might want to store the ddns logs persistently. To achieve this, you need to change the log file location by adding the following line in the global section of '/etc/config/ddns': config 'ddns' 'global' ... option 'ddns_logdir' '<your_custom_log_dir>' This option must be defined in the global section of the '/etc/config/ddns' file. If the option is defined at config service level, it will be ignored by the '/usr/lib/ddns/dynamic_dns_functions.sh' script and the log location will be defaulted to '/var/log/ddns'. To view logfile content from LuCI select the [Log File Viewer]-tab of desired configuration/section and press the [Read / Reread log file]-button. From console you should change to the ddns log directory (default '/var/log/ddns'). You will find a logfile for every configuration/section. cd /var/log/ddns ls -la cat myddns_ipv4.log cat myddns_ipv6.log Debugging To debug what's going on, you can run ddns-scripts in verbose mode. Following verbose level are defined: Level Description 0 Non verbose - No output 1 Output to console (default) 2 Output to console and logfile. Run once WITHOUT retry on error. 3 Output to console and logfile. Run once WITHOUT retry on error. Sending NO update to DDNS service. Before starting debugging stop all running ddns-scripts processes: /etc/init.d/ddns stop /etc/init.d/ddns disable validate that no ddns-scripts processes running: ps | grep dynami[c] Now you can start one configuration/section for debugging. To stop/break running script press [CTRL]+C. Replace 'myddns' with your desired configuration/section name and 'level' with the desired verbose level. /usr/lib/ddns/dynamic_dns_updater.sh myddns level You will get full description of errors and the output of programs like wget, nslookup etc. used by ddns-scripts Common errors Network and name resolution problems Check your communication settings with the following commands: nslookup google-public-dns-a.google.com ping -c 5 google-public-dns-a.google.com ping -c 5 -4 google-public-dns-a.google.com # (-4) force IPv4 communication ping -c 5 -6 google-public-dns-a.google.com # (-6) force IPv6 communication if installed wget -O- http://checkip.dyndns.com # for IPv4 wget -d -O- http://checkipv6.dyndns.com # for IPv6 needs wget package and IPv6 to be installed curl -v http://checkipv6.dyndns.com # for IPv6 needs curl package and IPv6 to be installed HTTPS/SSL problems Check if your DDNS provider ONLY supports secure requests and enable HTTPS (option use_https) in your configuration.

The relevant parameters to use together with a custom settings are: UCI option LuCI description Explanatory note service_name DDNS Service provider Inside LuCI set to '–custom–' or delete from '/etc/config/ddns' if you need to use custom update URL. update_url Custom update-URL Copy from description below, if necessary. domain Hostname/Domain The already registered name at your DDNS provider. Must be your public FQDN because used by nslookup command to check if the send IP update was recognized by your provider and published around World Wide DNS. username Username Normally your username but possibly used with different settings. password Password Normally your password but possibly used with different settings. If you find a at a provider description below, please support the ddns-scripts maintainer to test and update this page. Please post a support request if something is not working as described or needs to be updated. Thanks! If you find problem “Failed writing HTTP request: Bad file descriptor” in some server / wget version (see: https://bugzilla.redhat.com/show_bug.cgi?id=912358), it is worth to try changing the update_url in /etc/config/ddns from "http://[USERNAME]:[PASSWORD]path_to_your_provider_and_other_things" to "--user=[USERNAME] --password:[PASSWORD] http://path_to_your_provider_and_other_things" AND change one line in /usr/lib/ddns/dynamic_dns_updater.sh from update_output=$( $retrieve_prog "$final_url" ) to update_output=$( $retrieve_prog $final_url ) cloudflare.com Last updated: 2020-08-31 Homepage To use subdomains (CNAME or A records), use the format below when filling your credentials: domain {subdomain}@[zone] Examples: If the hostname is “sample.example.com”, the “domain” field would be “sample@example.com” if the hostname is “dev1.sample.example.com”, the “domain” field would be “dev1.sample@example.com” If using Cloudflare's “Subdomain Support”, your zone may already be “foo.example.com”, so if the DDNS hostname is “bar.foo.example.com” the domain field would be “bar@foo.example.com” The version of ddns-scripts in the master branch of the packages feed supports the use of API tokens.

To access it, log in to https://domains.google.com and go to Configure DNS for the domain in question, then scroll down to Synthetic Records and add a new one. It will issue a specific username and password for this hostname. Google requires HTTPS for updates, so be sure to also install package wget or curl in order to allow this. Use the following settings: service_name --custom-- update_url http://[USERNAME]:[PASSWORD]@domains.google.com/nic/update?hostname=[DOMAIN]&myip=[IP] domain [Your defined hostname] username [assigned username for hostname] password [assigned password for hostname] http_secure Enabled ca_path Set to "IGNORE" or download certs and provide path gratisdns.dk Last updated: 2015-07-20 Homepage (Danish only) Taken from OpenWrt forum GratisDNS.dk is only supported by ddns-scripts using custom service settings.

I have gone in contact with support of mythic-beasts.com. I will update as soon a solution is available. namecheap.com Last updated: 2015-07-21 Homepage – Knowledgebase Note that with the namecheap protocol, the username option is translated to the host argument in the update request. Therefore, it should be the host-part on the DNS record, not the username that you use to log into the namecheap.com site. To update multiple hosts you might need to define separate configuration/section for each host. To get your password, log into the namecheap.com site, enter the management console for the domain, and click the Dynamic DNS menu option. Currently ddns-scripts only supports the case where your dynamic subdomain has the same IP address as for your unqualified domain. Otherwise you will send updates to namecheap.com every “option check_interval” 10 minutes (default) because your FQDN is not validated. Proposed solution here, which you can easily implement yourself. (This may only be an issue for ddns-scripts 2.4). Let assume you define two FQDN at your domain “example.com”: “www.example.com” and “ftp.example.com“ To update only your domain record “example.com”: service_name namecheap.com domain [Your domain, here: example.com] username @ password [Your password] To update for example only your ”ftp.example.com” host: service_name namecheap.com domain [Your domain, here: example.com] username ftp password [Your password] To update all to the same IP address: NOTE: For namecheap updating multiple subdomains is NOT working nowadays, you have to make one request per subdomain, so configure one section per subdomain. https://www.namecheap.com/support/knowledgebase/article.aspx/29/11/how-do-i-use-a-browser-to-dynamically-update-the-hosts-ip#comment-936527059: service_name namecheap.com domain [Your domain, here: example.com] username @ -a www -a ftp !!! @ stands for your domain, www for www.example.com, ftp for ftp.example.com password [Your password] noip.com Last updated: 2015-07-21 Homepage – SupportCenter Starting CC 15.05 do not forget to additional install ddns-scripts_no-ip_com package. The default is to use your 'username' and 'password' as normal inside ddns-scripts together with 'service_name' 'no-ip.com' or 'noip.com'. If you want to update multiple hosts inside one configuration/section you need the following settings: service_name delete / --custom-- update_url http://[USERNAME]:[PASSWORD]@dynupdate.no-ip.com/nic/update?myip=[IP]&hostname= !!! After the 'hostname=' fill in a comma separated list of hosts to update. Sample: host1.example.com,host2.example.com,host3.example.com without any spaces in between. Sample: http://[USERNAME]:[PASSWORD]@dynupdate.no-ip.com/nic/update?myip=[IP]&hostname=host1.example.com,host2.example.com,host3.example.com domain [Only ONE of your defined hostnames, i.e. host1.example.com] username [Your username] password [Your password] spdyn.de (old spdns.de) Last updated: 2016-08-02 Homepage – Wiki/FAQ (German only) The web-pages of spdns.de are now reachable at spdyn.de. Currently updates send to update.spdns.de pages are still handled but produce warnings in DDNS update log at the provder. Created accounts and domains at spdns.de are still working without any problems. The default is to use your 'username' and 'password' as normal inside ddns-scripts together with 'service_name' 'spdyn.de'. If you want to use Update-Token, keep in mind that this token can only update the host it is generated for. Use this settings: service_name spdyn.de domain [Your defined hostname at spdyn.de] username [Your defined hostname at spdyn.de] password [The token generated for this hostname] If you want to update multiple hosts inside one configuration/section you need the following settings (Update-Token doesn't work): service_name delete / --custom-- update_url http://[USERNAME]:[PASSWORD]@update.spdyn.de/nic/update?myip=[IP]&hostname= !!! After the 'hostname=' fill in a comma separated list of hosts (max. 20) to update. Sample: host1.spdyn.de,host2.spdyn.de,host3.spdyn.de without any spaces in between. Sample: http://[USERNAME]:[PASSWORD]@update.spdyn.de/nic/update?myip=[IP]&hostname=host1.spdyn.de,host2.spdyn.de,host3.spdyn.de domain [Only ONE of your defined hostnames i.e. host3.spdyn.de] username [Your username at spdyn.de] password [Your password at spdyn.de] tunnelbroker.net Hurricane Electric provides a free IPv6inIPv4 tunnel through Tunnel Broker that demands a permanent IP or a real-time updated one. From its homepage: “Our free tunnel broker service enables you to reach the IPv6 Internet by tunneling over existing IPv4 connections from your IPv6 enabled host or router to one of our IPv6 routers. To use this service you need to have an IPv6 capable host (IPv6 support is available for most platforms) or router which also has IPv4 (existing Internet) connectivity.” Apply the following patch to include that service on OpenWRT DDNS [ -z "$(cat /etc/ddns/services 2>/dev/null | grep ipv4.tunnelbroker.net)" ] && echo "\"tunnelbroker.net\" \"http://[USERNAME]:[PASSWORD]@ipv4.tunnelbroker.net/nic/update?hostname=[DOMAIN]&myip=[IP]\" \"good|nochg\"" >> /etc/ddns/services Now you can configure your tunnelbroker ddns: #/etc/config/ddns config service 'HE6in4' option service_name 'tunnelbroker.net' option lookup_host 'hostToCheck.com' #Change it to yours. It should be a hostname updated by a DDNS with the current IP. option ip_source 'web' option ip_url 'http://checkip.amazonaws.com/' option interface 'wan' #Change it to yours option username 'tunnelbrokerUSERname' #Change it to yours. It's the same tunnelbroker login. option password 'tunnelbrokerDDNSpassword' #Change it to yours. It's not the same tunnelbroker login. option domain 'tunnelbrokerDDNSnumber' #Change it to yours. It's only numbers. option enabled '1' Instead of using a web service, that has the risk of being eventually offline, to detect the public IP, you can detect the WAN public IP by this script.
