[gentoo-user] [OT?] Dynamic DNS using Gentoo

[Jose Gonzalez Gomez]

Hi there,

I currently have a DSL connection with a fixed IP using a DSL router,
with an internal network of 4 computers with private DHCP IPs (except
the server, with fixed private IP). Now I'm considering changing to
another provider with dynamic IPs. I have three domains hosted in my
SOHO server (let's say example1.com, example2.com and example3.com)
including mail for two of them. The questions are:

1. Which dynamic DNS provider do you prefer and why (I would prefer a free one)?
2. Which is the best dynamic DNS client available in Gentoo, taking
into accout that it must be able to discover the DSL router's
dynamically assigned IP and connect with the chosen provider?

I would like to be able to keep my domain names, but using a dynamic
IP DSL connection, this is, I don't want to change to any URL like
example.no-ip.com or example.dyndns.org. So I thought I could just add
some CNAMEs entries to my DNS service (kind of www.example1.com CNAME
example.dyndns.org and mail.example1.com CNAME example.dyndns.org) to
get what I want, but here:

http://www.dyndns.org/services/dns/

they say the free service doesn't support using your own domain
names... does this mean that you must pay if you want to include your
own domain name in their DNS servers, but the whole CNAME stuff should
work if you have a DNS service available elsewhere? Has anyone ever
tried this?

Thanks in advance, best regards
Jose

Well, I think, this could be easy done by your broadband soho router.
Most of them have already support for all common dyndns providers...

I'm facing the opposite problem: I have gentoo-server with bind running
(with static IP, outside of my home network) and I'm looking for the way
my home router (asus wl500g) with dyn-ip could use it as dyddns instead
of dyndns.org...

Heya, I faced rather the same problem and solved it as follows:

I provided a CNAME record within my zone (being served on my public inet host)
that points to a dyndns record. This gets updated regulary using ddclient then


Well, this is still a solution that *depends* on services like dyndns, but the 
other solution would be in enabling the mysql useflag, and writing a cgi 
script - that could be invoked via wget for example - that updates teh mySQL 
records within your own controlled zone; 
(but I didn't find the time to write this yet)

Christian Parpart.

I currently own a 3com 812 router (a bit outdated) so I think I don't
have that functionality built in the router. Anyway, I have taken a
look at ddclient (suggested by Jean) and seems to have some kind of
support for my router...

Thanks, best regards
Jose

Jose,

I'm currently DHCP behind DSL so I have the kind of setup you're looking at.
Apart from the obvious configuration things you'll have some other things to
keep in mind, like who is doing the DHCP negotiation for the IP address?  If
the router is, it must be able to interact with the dynamic dns service,
otherwise you get into having to script something on the server side to
fetch the ip info from the router and connect to the remote ip address when
a change takes place.

I don't think you'll find a free service that allows for hosting your own
name... Trust me, the small fee for dyndns.org is worth it to keep things
working.  With the fee in place whenever my ip address changes I can ping
dyndns.org to have the ip address change and, so far, I have no complaints
about it at all.

As for the software, look for ez-ipupdate.  It handles most of the dynamic
dns sites including dyndns.org and others.

In any case ez-ipupdate might be a good source for dynamic dns services; if
ez-ipupdate handles it then it's typically a good service.

It seems I don't have support for this on the router, so I'll have to
go the scripting way... I have taken a look at portage, and ddclient
and ez-ipupdate are available.

Well, I was searching for a free service because if I have to pay
anything for this I would consider paying a cheap hosting instead of
mantaining my own server.

Thanks for the tip... I basically have found (from the suggestions on
this thread, thanks everybody) the following providers with some kind
of free dynamic dns service (in case anyone else is interested):

http://www.dyndns.org/
http://www.dyns.cx/
http://www.zoneedit.com/
http://www.no-ip.com/

Thanks, best regards
Jose

I believe ddclient is the standard client; it works like a charm; the
config file already has it all set up for dynsys.org or zoneedit.org, so
it's fairly easy; it can be on any of your computers, ie not necessarily
on the router - of course it has to be awake all the time though.

Well, what else would you expect of such a program? :- )

cheers

I have negative emotions about them. They have limitation only to five
domain names. I was tried to add my five domain names there. Four
domains appeared in them servers in more than week. I'm still waiting
for appearing 5th domain (more than month :)

Of course I didn't contact them support, just changed DNS provider...

btw, I think its not the best service for dynamic DNS :-)

Cheers!
