Overwrite tmnet DNS in router DIR-615

In the past, I have read into how the site was "blocked" in Malaysia where web surfers unable to load some websites. I don't know what is the fuss about it as it certainly create a lot of talks in the social websites. The term blocked would probably be at IP level where if the access by a machine to a address of IP a.b.c.d is unreachable, then that is a really blocked. But the funny things is, some ISPs in malaysia do not actually blocked the IPs but merely make some hostname unable to resolve into IP.

So in this article, I'm gonna show you how you can get back your freedom. There are many public DNS out there. Just google public DNS would give you a lot of list. In fact, google has public DNS too. When you choose the DNS, be sure it is public trust able and speed of your machine to the DNS server is matter when you want a quick web browser able to determine the IP address quickly.

With that said, I'm gonna show you how you can overwrite the DNS entries in tmnet router DIR-615. You need to ssh to your router in order to accomplish this. I have tried many times in the web interface, though it has text box for you to specify, apparently you cannot specify to the list that you want, it always default to tmnet DNS. This is annoying!

What you need is a terminal, ssh program installed, username = operator , password = h566UniFi

After you have ssh into the router, these are all the steps you need to do.

# cat /var/etc/resolv.conf
# This file is generated by gen_resolv.php
nameserver 1.9.1.9
nameserver 202.188.0.133

# sed 's/1.9.1.9/192.168.10.2/' -i /var/etc/resolv.conf
# sed 's/202.188.0.133/8.8.8.8/' -i /var/etc/resolv.conf
# cat resolv.conf
# This file is generated by gen_resolv.php
nameserver 192.168.10.2
nameserver 8.8.8.8

So I have an internal IP because there is a internal DNS service running. 8.8.8.8 would be the google public DNS.

Well, that's all you need, the site where it is unable to resolve to an IP, you can check by ping to the hostname, it should return a valid IP. That's all folks, I hope you learn something and gain back your right.
