For those dealing with Linux and/or OpenWRT firmware (that includes DD-WRT), you can update your network if you are using dynamic assignment with the curl command

# curl -k -u username:password https://updates.opendns.com/nic/update?hotsname=network

Some help for setting OpenDNS up on Altel/Windstream, DSL for the SpeedStreem 4200 DSL Modem.

1st. Login to your modem at: http://192.168.254.254/

2nd. Go to “Setup” then “DHCP”.

3rd. Change the Primary DNS Server to: 208.67.222.222

4Th. Change the Secondary DNS Server to: 208.67.220.220

5th. Click the “Apply” button then reboot the modem, so the new setting will take affect. If all went well your network should be using OpenDNS.

SWEET!

@ Gloria Justice:
You would change the DNS settings in your router, not on each computer. There is no software to install for this.

The software is for a dynamic IP updater, which is useful if your ISP assigns IP addresses dynamically (this means that you do not have a static IP address that never changes). If you do not plan to make use of OpenDNS network Dashboard, or the filtering/blocking services, you would not need it. The OpenDNS Updater simply alerts your OpenDNS account when your IP address changes, so that these other services will continue working. Again, it is not needed to simply use the OpenDNS servers rather than your ISP DNS server.

Unfortunately, I don’t think any of this is going to resolve an issue internal to your home network. What is the problem you are having?

@Jeremy, @Shizzle:

I am thinking Shizzle means an OpenDNS Updater client for Linux. If that is the case, it’s a cron job.

I am in the middle of setting up a server at home that will be a model for other networks I will set up.

The server is running Ubuntu 8.10 with LAMP, BIND9, SSH, SAMBA and some other stuff.

The server will NOT be exposed to the internet (behind a firewall and NAT), but as networkconnections are slow here, I would like to run it as a caching server for the lan as well as resolving for the servers on the lan (yes, homenetwork with multiple servers ).

I am not a stranger to editing configuration files, but prefer using Webmin. So it would be very nice to see a step-by-step tutorial on how to set up this using Webmin. And who would be better at doing such a tutorial than the people behind OpenDNS? Of course, I use OpenDNS as the forward DNS (right term?).

@Jeremy, I meant an updater client, sorry ’bout that. I find it inconvenient to have to log into OpenDNS or DNS-O-Matic to update my network settings and apply my “filtering” when I boot up, not DNS configurations.

There is an updater client for Windows and Mac that update network settings upon boot up to ensure you receive content filtering if you choose to use it. I haven’t found a Linux one, that works anyway. I tried ddclient but could not get it to work. I guess I could leave my Windows machine on all the time and update my network settings that way but no one’s home most of the day so why bother.

My DNS configuration does not work by editing the resolv.conf, I set my DNS configuration at the router level, so all my machines use it automatically. But thanks for the info.

Your site caught my eye… looks amazing! I am in the midst of trying to solve a DNS problem with one of the three computers we have on our home wireless internet system. If I installed your software on one of the operational computers would it help me solve my problem, or do I need to have all three computers able to communicate with the web before downloading OpenDNS? Just curious. Thanks.

@Shizzle. Linux already has an official OpenDNS client. It’s called /etc/resolv.conf.

How else do you think your DNS configuration works?

What would a “Official Linux OpenDNS” do? I have no idea, as there exists none for any other operating systems, so I really have no idea what you’re getting at.

Or better yet, when are we going to see an official Linux OpenDNS client that actually works. I have tried some of the hack jobs available out there to no avail. All my home machines run Ubuntu and I really haven’t had the chance to update my firmware with DD-WRT and configure it.

As a DD-WRT OpenDNS user I can only add,

/usr/sbin/iptables -I FORWARD 1 -p tcp -d 208.67.222.222 –dport 53 -j ACCEPT

/usr/sbin/iptables -I FORWARD 2 -p tcp -d 208.67.220.220 –dport 53 -j ACCEPT

/usr/sbin/iptables -I FORWARD 3 -p tcp –dport 53 -j logdrop

Thanks for the great service OpenDNS!

rchk,

From my point of view (at least), there actually isn’t a whole lot of information there.

You can find out about:
- Basic Setup (straight from OpenDNS generic instructions
- set up a dynamic IP
- Intercept DNS Port

Anyway, like I mentioned above, would be great to have some “official” instructions for some of the popular open-source router software, like DD-WRT and Tomato.
