 ever since dyndns stopped to be completely free (including hassle-free) i was looking for alternatives. i recently stumbled across RFC2136 which can be used to provide dynamic dns services. since i have access to two nameservers running bind i decided to try it out.. it works pretty nicely :) ever since dyndns stopped to be completely free (including hassle-free) i was looking for alternatives. i recently stumbled across RFC2136 which can be used to provide dynamic dns services. since i have access to two nameservers running bind i decided to try it out.. it works pretty nicely :)
  
-this is an improved version, now that i know more about bind, over my previous setup and it has been updated to work with bind 9.16 which no longer creates TSIG keys using ''dnssec-keygen'' but instead uses the much more comfortable tool ''tsig-keygen''. The main disadvantage of my previous setup was, that any user holding one of the allowed keys could update any host entry, so the user was not limited to a single hostname which can be a seurity issue. +this is an improved version, now that i know more about bind, over my [[diy_rfc2136_dyndns_with_bind&rev=1624605040|previous setup]] and it has been updated to work with bind 9.16 which no longer creates TSIG keys using ''dnssec-keygen'' but instead uses the much more comfortable tool ''tsig-keygen''.

 this following howto will explain how i did my setup so that i could have a little bash script that would allow me to add new hosts to my dyndns with a single command. all my hosts will end with .dyn.mydomain.ch.  this following howto will explain how i did my setup so that i could have a little bash script that would allow me to add new hosts to my dyndns with a single command. all my hosts will end with .dyn.mydomain.ch.
