Following modification was tested with ADSL and Cable, if you are behind a router (ex. Dlink 614), please set use=web instead of use=if in your /etc/ddclient/ddclient.conf

Using ddclient v3.6.2 behind a Zyxel 642R ADSL router (NAT'ed access) which is my eth network gateway, I use the below listed ddclient.conf file. First get ddclient with:
e.g. first do a
to see what ebuilds it will install
Ddclient comes with a default conf file "sample-etc_ddclient.conf" inside /etc/ddclient/, just rename it to "ddclient.conf" by
| Code: | | cp sample-etc_ddclient.conf ddclient.conf |
This way you still have the "sample-etc_ddclient.conf" as a backup in your /etc/ddclient/ folder.
Now to the ddclient.conf:
etc/ddclient/ddclient.conf

If you have a custom account you need to set your custom date in the "dyndns.org custom addresses" section. Make sure to set:
I started ddclient with:

works like a charm. |

Hello,
I've got 2 questions.
1. I use the DynDNS offerd domain name my-host.is-a-geek.org. Should I set the custom variable to "yes" or not?
2. I use the -fw switch to fetch the ip-adress from my modem/router/switch and set ddclient to run as a daemon every xyz minutes. Does this mean that ddclient will update my dns entry at DynDNS.org every xyz minutes or will it poll my modem/router/switch every xyz minutes and only update the entry at DynDNS.org when my IP has changed?
It is quite stupid I ask these questions here, but the documentation fails to do so. Thanx in advance for anybody who could help me!
Kind regards,
A belgian Gentoo user |
