Update Client Configurator – 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
inadyn can be run directly from the command line like so:
inadyn --username test --password test --update_period_sec 600 --alias test.homeip.net inadyn -u test -p test --update_period_sec 600 --dyndns_system email@example.com --alias your.domain.tld
Here is a basic template which provides the various options available.
update_period_sec 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 firstname.lastname@example.org, email@example.com, firstname.lastname@example.org dyndns_system email@example.com alias your-dynamic-host.dyndns.org alias another-dynamic-host.homeip.net
Here is a minimal inadyn.conf file designed to update a single dynamic DNS host.
# Basic configuration file for inadyn # # /etc/inadyn.conf update_period_sec 600 # Check for a new IP every 600 seconds username test password test dyndns_system firstname.lastname@example.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.
