Download: The most recent version of inadyn we have vetted can be. IP Detection inadyn supports detecting the public IP address via our service. System Compatibility inadyn officially runs on Linux, Windows, Mac OS X, and OpenBSD.
Configuration File – Generate your conf file after reading how to run inadyn inadyn can be configured by command line options or by a configuration file. A default configuration file is /etc/inadyn.conf under Unix systems.
The location of the config file can be given to inadyn via the -inputfile option. Example 1 inadyn can be run directly from the command line like so: inadyn -username test -password test -updateperiodsec 600 -alias test.homeip.net inadyn -u test -p test -updateperiodsec 600 -dyndnssystem custom@dyndns.org -alias your.domain.tld Example 2 Here is a basic template which provides the various options available.
Updateperiodsec 600 # Check for a new IP every 600 seconds # Enter your Dyn username and password here username your-login # your Dyn username password your-password # your Dyn password # What kind of host is being updated? Choices are dyndns@dyndns.org, statdns@dyndns.org, custom@dyndns.org dyndnssystem dyndns@dyndns.org alias your-dynamic-host.dyndns.org alias another-dynamic-host.homeip.net Example 3 Here is a minimal inadyn.conf file designed to update a single dynamic DNS host. # Basic configuration file for inadyn # # /etc/inadyn.conf updateperiodsec 600 # Check for a new IP every 600 seconds username test password test dyndnssystem dyndns@dyndns.org alias test.homeip.net Issues To Be Aware Of.
The DynDNS update protocol supports MX, BACKMX, WILDCARD and OFFLINE options, but inadyn does not support these. Entering these options in the inadyn.conf file will result in inadyn failing. inadyn currently only supports updates via http. Updates over https are not supported at this time. inadyn only supports updating hosts for one system type at a time. Dyndns, statdns, and custom cannot be mixed within the same configuration file. Running inadyn from the command line is a security risk because your password will show up in the process table.
Be careful if you run it on a machine with multiple users.
Contents. Dynamic DNS Introduction Every computer attached to the Internet has an IP address. Name Translation is the process of relating a name (like 'www.google.com') to an (like '74.125.19.103') so that a website (or other service) on a computer can be accessed using an easily remembered name, rather than the IP address number of the computer. Name Translation is implemented via a distributed database known as the. This database is implemented on the Internet by which keep track of DNS records and exchange this information between each other to maintain consistency.
Every request for a name (ie. A web browser) is then directed to one of these name servers. Most servers on the Internet have a that never changes. The DNS record for this node will only change infrequently. However, many home users are assigned an IP address that changes more frequently. These are assigned by an. This makes it a challenge to translate a Name to one of these IP addresses.
A number of DNS name servers offer a method to update the DNS database with dynamic IP name translations. This is accomplished by using a small software utility on their computer or a local router.
These Dynamic DNS services allow the user to choose a hostname and set an initial IP address to correspond to that hostname. The software utility then periodically checks for a change to the computer's IP address, and when a new IP address is discovered, it updates the Dynamic DNS database to reflect that change.
Registering with a Dynamic DNS provider DNS requires that a name server somewhere on the Internet keep track of 'where you are' (i.e. Your current IP address). That is, its database must always be updated to make sure your hostname always corresponds to your current IP address. In order to use one of these Dynamic DNS services, registration is required first.
Here is a selection of these services (a full list is available and at ):. Upon registering, you will select a username and password, as well as a hostname that you will use as the DNS name (to allow external access to your machine using the hostname). Many Dynamic DNS providers offer a selection of hostnames available for free use with their service. However, with a paid plan, any hostname (including your own registered domain name) can be used. Setting up Dynamic DNS service updates Once you have chosen a Dynamic DNS service provider, you need to set up a way that your IP address record will be updated whenever it is changed. There are two ways of doing this:. using a dynamic DNS software utility that is installed on your computer.
using the built-in capabilities of a cable/DSL modem/router Many router/modems support Dynamic DNS reporting/notification/updating directly. If your router's configuration is accessible from a web browser, try accessing it by logging into the local IP address of your router (for example, or ) and look for the Dynamic DNS (DDNS) settings. However, even if your modem/router does support dynamic DNS reporting, there are cases in which you may wish to use a software utility on your computer to perform the updates anyway:. you are using several Dynamic DNS services at once (most routers only accommodate one service at a time). the router does not support your particular Dynamic DNS service. your server is on a mobile computer (e.g.
Laptop) which is not always connected to the same network/router/modem. Using a software utility to perform Dynamic DNS Updates There are several available utilities. Each Dynamic DNS service may work better with a particular utility.
(You may need to add the Ubuntu Universe to your set of software repositories to install some of these utilities. See.) ddclient is the original Linux utility for dynamic DNS updates. Lists some configurations for several Dynamic DNS services. More info can be found on the.
The following section has been adapted from. Install ddclient using a software package manager, or using the command-line interface: sudo apt-get install ddclient If this is the first time you have installed ddclient, you will be prompted by the installation script for the hostname(s) that you registered with DynDNS (or other Dynamic DNS service). You will also be prompted for the username/password your registered with your Dynamic DNS service.
Lastly, you will be asked which ethernet port you primarily use to connect to the Internet (eth0 for wired or wlan0 for wireless, usually). Most of the time this is all you will need to do for the utility to function correctly. You can also later edit the ddclient configuration file, however, to suit your specific needs (or if you make changes to your service, hostname, or other variables). Edit the ddclient configuration file (using kate instead of nano in Kubuntu, or gedit instead of nano in Ubuntu): sudo nano /etc/ddclient.conf.
To set the number of seconds between updates, I add the line daemon=3600 My dynamic IP only changes rarely, so I only check it hourly (3600 seconds in an hour). To use secure SSL communications, I add the line ssl=yes. To use the DynDNS checkip service (which will autodetect your current IP address), I add the line use=web, web=checkip.dyndns.com/, web-skip='IP Address' My configuration file now looks like: # Configuration file for ddclient generated by debconf # # /etc/ddclient.conf # # Check the current IP address.
Master
Either check the eth0 port for its current IP address (can't be used on a LAN), # or use the DynDNS IP checking service. Daemon=3600 pid=/var/run/ddclient.pid #use=if, if=eth0 use=web, web=checkip.dyndns.com/, web-skip='IP Address' # # Login and change the values at the DynDNS site, using SSL.
Protocol=dyndns2 ssl=yes server=members.dyndns.org login=myDynDNSusername password='myDynDNSuserpassword' mysite1.dynds.org,mysite2.dyndns.org,mysite3.dyndns.org Note: if this doesn't work, try changing web-skip to 'Current Address' Note that the password must be enclosed in quotation marks, e.g 'myDynDNSuserpassword' for DynDNS. To use ddclient with free dynamic DNS service, the configuration file is as followed: # ddclient configuration for Dynu # # /etc/ddclient.conf daemon=60 # Check every 60 seconds. Syslog=yes # Log update msgs to syslog. Mail=root # Mail all msgs to root. Mail-failure=root # Mail failed update msgs to root. Pid=/var/run/ddclient.pid # Record PID in file. Use=web, web=checkip.dynu.com/, web-skip='IP Address' # Get ip from server.

Server=api.dynu.com # IP update server. Protocol=dyndns2 login=myusername # Your username. Password=YOURPASSWORD # Password or MD5 of password. MYDOMAIN.DYNU.COM # List one or more hostnames one on each line. MYDOMAIN.COM Note: refer to this for more information about updating subdomains. Ensure that the configuration is working: sudo ddclient -daemon=0 -debug -verbose -noquiet. Note that you can add additional services and/or domain names to be updated simply by adding an additional block to the configuration file (appropriate for the service).
Here is an example (see below for references to additional examples). Protocol=otherDDNSservice server=whatever.ddnsservice.org login=MyOtherDDNSserviceusername password=MyOtherDDNSservicepassword mysite4.dnsservice.org, mysite5.dnsservice.org Troubleshooting The following details a used to repair a ddclient setup. Remove/purge all of the previous install attempts: sudo apt-get remove -purge ddclient. Install ssh & ssh socket so that you can send your password via ssh instead of in the clear: sudo apt-get install ssh libio-socket-ssl-perl Note: ssh w/ddclient won't work without libio-socket-ssl-perl, so make sure that you install that even if you have ssh already installed.
