dynamic ip and DNS how to

dasbooter · 02-22-2006, 02:42 PM

I recently changed my ISP provider to one that uses dynamic ip addresses. Can somebody get me started on how to configure one of these setups that allow me to alias a dynamic IP address to a static hostname. I am a bit overwhelmed by the info I have read so far. It seems that I will require the services of DynDNS.com or NO-IP.com and a client that will update my ip address to there servers to provide redirection.
I could really use some direction on which service to use and which client to use (and how to set it up).
In terms of client I would like something with low overhead but I am looking for feedback on which one to use. My ip address does change quite frequently so I guess a client running as a daemon might be best but a script that runs just when the ip address changes would be good. I can use webmin to some extent if that is of any help.

Important info :Suse linux 10.0
DSL connection

Linux experience

ver a year but still only compile when I really have to (Suse babies u I am afraid). Have a small home network. Regularly break things really well but I am always willing to try new things

Here's a guide, but it's more tailored toward Debian. Maybe it'll help some...

i'd say use dyndns. i've used that before in a client setup.

check their KB for more info:

http://www.dyndns.com/support/kb/

the last time i used it is that you just register, pick the domain and run the update client on your machine. i think that's the same proc that is in use.

Did you use the ddclient they recommend or something else for the client born4 ? Was it relatively easy to set up? Did it require a lot of resources ? I am trying to remote to this system and I have noticed some slow down already with 2 users and all there processes running at the same time.

yup. it was ddclient. but that was before they made changes to their service. the client is not that much demanding in terms of resources. just runs a few times a day to update your dyndns profile
but that was over a year ago. i've never tried the version in their support site right now.

I'm using ddclient 3.6.6 and have had no problems with it - I'd recommend it.

You said you had a small home network. If so and you have a little soho router, then let it handle it. Most of them support DynDNS out of the box.

uggh this shift work is killing me sorry I havent replied to this thread sooner.

My first foray into linux was to resurrect an old system and turn it into a router so no store bought router.

I may try ddclient or maybe I will get one of the windows machine in the backround to do it as I understand after reading some more that most clients can ascertain your external IP from an external server. Right now I am working on making my Suse connection stay up all the time as I use to have it dial up on demand which seemed convenient and maybe a llttle more secure.

Thanks all for your helpful responses

If I find anything out of the ordinary or mangage to say, train the cat to update my ip address I will be sure to post back.

As for useful information for this thread, some distributions are starting to come with Dynamic DNS update clients either already installed or available through their update databases (SuSE=yast?).

and some more useless dribble: 'ISP provider' would be Internet Service Provider provider

dasbooter · 04-24-2006, 04:44 PM

In the end I ended up using the official windows client on a windows box in my lan. It works fine besides I have to find something for my windows box to do it was getting lazy
