Anyway to change DNS

Would like to edit my DNS settings on this. Is it possible? After hearing what sounds like a DNS poisoning, would like to swap out TMOs DNS for another provider.

Grab anycut off the marketplace.
Long tap on the desktop -> shortcut -> activity -> ip settings.
I've been using openDNS from the moment I got the phone. Works like a charm.
edit - shouldn't have replied that quickly... this only works for WiFi as far as I know... but I haven't tested that. Will do so now.
edit 2 - well... scratch all that. I just tested opendns on both wifi at my home and using edge and both did not work. I guess ip settings doesn't work?

That is a nice find for when you are on wifi. It doesn't change your DNS when you are on the network. I have also wanted to change my DNS to Opendns but have not found a way to change dns on data connection. Any help would be appreciated.

Can you confirm that is works for wifi? Opendns.com/org isn't showing that it's working for me.

Ummm opendns.com/org doesn't work for me and I am on opendns

Stupid question: why are you worried about DNS poisoning? I'm aware of what it is, but I'm not aware of how someone would exploit it.
They'd have to find an exploit on T-Mobiles DNS servers (or the higher servers that they receive the information from), that would either: a) use a "fake" higher DNS server to get info from, one that would provide spoofed entries, or b) insert fake entries into the cache. Correct?
Curious as to why you'd be paranoid about this tbh. Even with OpenDNS, if there's an exploits on T-Mobiles servers, wouldn't they be able to exploit it on the edge/3g servers? And if OpenDNS were ever compromised, it would leave hundreds of thousands of users more vulnerable, vs the (very) few people who use their cell phone for web banking.

Confusing syntax on my part. I meant .com or .org.

Guess you don't frequent boards as much as myself. It has already happened twice now. Just search for browser hijacked...
Being it has only been on Edge/3G, it must be their DNS. WIFI has never been affected.

Open an adb shell or Terminal Emulator and type
Code:
setprop ro.kernel.android.ndns 2
setprop net.eth0.dns1 208.67.222.222
setprop net.eth0.dns2 208.67.220.220
Those are ip addresses for OpenDNS, so use your own if you want something else. It might not be persistent through reboots though. If it isn't, append it to init.rc. I can't test this on actual hardware right now but on the emulator it does pass OpenDNS's test (in the upper right corner). Make sure you set the properties before opening the browser.

thanks trying this now and it seems to work well

Not only will it not persist on reboot, it will not persist over DHCP, so every time it reconnects to the network, this will have to be redone.

well, dunnow if you'v seen this
Mobile or other devices :
DNS servers are typically specified under advanced wi-fi settings. However, as every mobile device uses a different user interface for configuring DNS server settings, we provide only a generic procedure below. For more information, please consult your mobile provider's documentation.
To change your settings on a mobile device:
1. Go to the screen in which wi-fi settings are specified.
2. Find the screen in which DNS server settings are specified.
3. If there are IP addresses specified in the fields for the primary and seconday DNS servers, write them down for future reference.
4. Replace those addresses with Google IP addresses: 8.8.8.8 and 8.8.4.4.
5. Save and exit.
6. Test that your setup is working correctly; see Testing your new settings below.

that only works for wifi or 3g connection as well?

I think the only way you can use T-Mobiles network is through there DNS. I think they have it locked to that. I remember when I used to tether if you right clicked a picture (that is on the internet obviously not on your hard drive) and went to properties it was never listed just the url that it was supposed to be it also had an ip before that url. That ip was always the same no matter what site. I think there is a proxy running on one end or the other.

Prove that google dns is faster than opendns, it hasn't even been out for a week yet while opendns is very mature.

This benchmark would have to disagree with you.
http://gizmodo.com/5420931/namebench-helps-you-find-the-fastest-dns-server-for-your-computer

It is highly dependent on your location. Google DNS might be faster than OpenDNS for some, while UltraDNS might be faster than Google DNS for others.
Try out the benchmarks yourself to see which one is the fastest for you. I use OpenDNS myself.

google dns is not at the moment everywhere the fastest but dont worry it will be. suggest you dont use this for t-mobile nl tv coz this wont count for your download limit and wont add to your download fair-use-time other dns probably will

tried nice worked on x10

Change your phone to google's DNS instead of carrier's

I just want to share this link that i came across today by HTCdev. Hopefully this helps some of you guys. It claims it's going to help 3g/4g speeds!
htcdev.net/topic/229295-download-flashable-google-dns-zip/

It look interesting.
Thanks

Has anyone done this? Did you notice a speed difference?

Will try it tonight. If Google's as good as they look, this might own. I already use Google Voice to SMS over data.

I tried and my speeds increased from 315 to 458 and 22 to 87 kbps, download and upload respectively (tested in a 8th floor office bldg).

I won't say I don't believe you, but it is impossible that only using another DNS server increases the upload/download speed.

Actually, that's not true. It has to do with pipe bandwidth and speed. Verizon obviously isn't as big as Google, and they also can handle better servers, it also has to do with where you are in the world, and on their network, and what you are doing. Google's DNS servers are configured and made for SPEED and speed only. Verizons DNS can also be bottlenecked to ensure "data consistancy" as they have came out and said before.
Chris says it better than I can though.

LOL I got it thanks. Speedtest i was getting 1.95down and 1.48up before but using this I get either a really good test score or really bad. ex. one time it will be 2.59down and 1.75 up and next time ill get 0.25down0 .5up-- permissions are different for these files as apposed to the files in the zip. i changed them to match the directory but it diddnt change anything

DNS just translates URLs to IP addresses. I don't see how it would help upload/download speeds once you've connected to a site, but a bad DNS server will make connecting to a site take a while. Slow DNS servers make it take longer to find the site, but once it's found, how would DNS matter?
This script requires you to run it with an argument telling it which ppp device to use, ppp0 or ppp1 (does android even use ppp? mine doesn't but it's a Nexus One that doesn't have anything added by any carrier). If you don't supply it with an argument, it won't do anything. It will skip the first half of the script and enter incorrect information in the second half.
(it tries to enter things like: "net.$NAME.dns1", the $NAME variable is the same as the argument you use to run the script. If you don't use an argument, it will enter "net..dns1")
The script is placed in /etc/ppp/ip-up, meaning it is supposed to be executed when the ppp daemon detects a ppp connection. I don't think the ppp daemon can run it with arguments.
I personally don't see how flashing this script would do anything at all.
Just open a terminal emulator and type:
su
echo "nameserver 8.8.8.8
nameserver 8.8.4.4" > /etc/resolv.conf
voila, DNS changed!

When loading a website, it's loading things from everywhere, for example, on my website, it loads things from Google Analystics, my Godaddy Grid Server (which is a bunch of different addresses), Statcounter, and ads. Each lookup takes take time complete and resolve. As far as file transfer, it has absolutely nothing to do with that. That's between you and the server you're downloading from, as well as the load of the server itself.
Does that command change the DNS permanently?

Hey can you repost this if possible? The original link doesn't work and neither does the one you provided.

another option...
This is a cool script, but I prefer to use Masqed Crusader app. It does the same thing (Google DNS) but adds Local Nameserver Caching and Ad-blocking. And it can be turned off and on just by hitting a button... no permanent changes.

[Q] DNS Suffix on Andriod

Within my company we use a DNS suffix to connect to the internet/intranet. Without that DNS suffix you can not do anything. Does anyone know how to add this within android. Also it is not an IP rather a FQDN.
Thanks!

Add
Code:
search example.com
to resolv.conf. FWIW, what you are doing is pretty much broken. (As for "you cannot do anything, that is simply not true, the name resolution will not work without specifying FQDN - i.e., will not autoappend domain-suffix - that is all.)
Not really sure whether the DHCP client on Android supports this (ISC DHCP v4 does support DHCP option 119).
Also, unless the dhcp client gets run with -R option (talking about isc-dhcp here), resolv.conf will get overwritten.
IOW, fix your DHCP/DNS to use FQDNs everywhere.

Thanks for the help.
So basically there isn't a way to do this on android because of the broken functionality? I don't have access to the servers to change the way the DNS works.

Well, I pretty much see this as a non-issue. Simply use FQDNs for whatever you need and that is all; "we use a DNS suffix to connect to the internet/intranet" does not make much sense really.

Okay. Let me put it this way. I cannot access www.google.com (or any network resource) on any pc without adding example.com to the DNS suffix list under the advanced properties of ipv4 in the network adapters properties. Because there is no option like this on android I cannot browse the web, or access anything. All you get is this page could not be displayed.

P.S. Regardless the above (since I do not feel like debugging the über-broken network setup in $your_company for much longer). Kindly note the IP address, netmask and gateway settings you get when using DHCP. Then go to WiFi settings, select Advanced, check Use static IP, input the details noted before there and stick 8.8.8.8 and 8.8.4.4 to the DNS1/DNS2 fields. This way, you can browse internet just fine using Google public DNS servers.

[net.rmnet0.dns1]: [68.28.154.91]

[dhcp.eth0.dns2]: [192.127.43.152]
[dhcp.eth0.dns3]: []
[dhcp.eth0.dns4]: []
Thats the output. But I tried putting in google's DNS like you said and I get nothing.

Well, simply put - assuming 153.80.17.120 and 192.127.43.152 are those DNS servers of your company (I cannot see any WiFi anywhere in the output you posted, maybe your phone is special and calls wifi iface as eth0 instead of wlan0) - those are supposed to resolve www.google.com or whatever else. With or without any idiotic suffix. You can check this like
Code:
nslookup www.google.com 153.80.17.120
on a Windows box (or in a similar way on Linux/MacOS). If they do not do this unless you use the suffix, then your network admins need a kick in their ass and that is the end of the story. Sorry, this is not an Android problem at all.
P.S. Not really sure what you mean by "get nothing", getprop should show the Google servers instead of your broken ones once you have done that.

Alright. Thanks for your help.
If anyone else has a solution please feel free to help me out.
Thanks!
P.S. I'm using CM7 on an Evo 4G

How to get around tethering detection

As you all know most US (and i believe other) carriers try to charge us more for the data we already pay for if we want to use it in any method besides from our phone. There are a lot of apps that claim to get around it and it works for some and not for others, after some extensive google-fu and research i have found out that most if not all carriers use one of two methods of detecting tethering. 1.if the built in tethering is used the phone will use a separate tether specific apn 2.they look at the TTL of a packet, if tethering is being used the TTL will last past the WAN of the phone.
So i set out to try and find a way around this and a method of tethering that would work safely for all and get around TTL detection and i believe i have now found it.
Things you will need:
-Root
-ConnectBot
-ProxyDroid
-PDAnet (or any other tethering app)
-Something to SSH into
I will post more detailed instructions with screenshots and such if anyone wants but for now ill just keep it simple. Make sure your phone is on 3/4G. Open ConnectBot and connect to your ssh server, bring up the options menu and select port forwarding. Setup a dynamic (socks) proxy on port 8080 (or w/e you feel like) now open proxydroid and set host to 127.0.0.1 and make sure to enable global proxy (this does not work on all phones if it does not work for you then there is not much you can do) now open up a browser and go to any of the various ip checking sites and make sure your ip is showing up as the ssh servers ip and not a mobile one. Now enable pda net and do the same from the tethered device. If the ip is showing up as the remote servers then congratulations you are now tethering and they cant see the packets going to anything but the phone because everything is contained within the SSH session. Meaning the TTL on packets will end at the phones WAN as they expect them to.
I have been doing this on AT&T for some time now (around a month) and so far they have not found out and all is well, hope this helps at least a few people good luck!

Thanks

Has anyone been able to get this working. Whenever I select "Global Proxy" in ProxyDroid, I get no data. I changed the host to 127.0.0.1, but should I leave the port to default 3128 and Proxy Type to HTTP? Is there any other changes I should make in ProxyDroid? Thanks

Make sure you set the user agent on your computer browser to mobile. Had to do tethering for a client few days ago, and that was the problem. For Firefox and Chrome there are plugins for it.

Thanks for your response....I haven't gotten to the PC as yet. I am don't get any internet connection when I enabled ProxyDroid in with Global Proxy checked. And the OP said to make sure it is selected. So this is where I am stuck. Not sure whether I need to do any other configuration in regards to ProxyDroid. But thanks for your help.

Important feedback needed regarding OnePlus 6 OXYGENOS

After reading the topic below I would like to ask some feedback from fellow XDA members:
https://forums.oneplus.com/threads/secondary-dns-forced-to-8-8-8-8.999920/
What needs to be done from your side:
You need to be on OxygenOS, not custom rom.
Make sure DHCP (your router most likely) feed LAN devices with a single DNS server
Check your OP device if it assigns itself Google DNS as a second dns server. To do so just tap on the connected WiFi (Under Settings -> WiFi & Internet -> WiFi) and scroll down where the DNS Field is.
If that's the case, at least in my mind this is a privacy violation (who asked my permission to feed google with all my resolving data?) at least.
Could I have some feedback on this please?

Never noticed this before...you ask a valid question in my mind. Hopefully someone can give us some reliable feedback. It appears that you can choose to use a static IP in the WiFi settings and enter two of your own DNS addresses. If that is the case then you can use the same one that your router uses or one of those that doesn't track you???

The OS shouldn't add a DNS server on its own so it would be good to find what's causing this issue for you.
What I can say is that Omnirom does no such thing, just checked on my device

This in not just me, there are plenty of people reporting the same on the provided link.
Also, Omnirom or any other custom roms are unrelated.
I'm interested in OOS feedback.
Please don't derail the thread

You didn't specifically mention OOS in your first post so I figured it was worth pointing out that it appears to be an OOS issue, not a general pho n/vendor/driver issue.
FWIW, the DNS settings should be somewhat irrelevant anyway since Pie offers the private DNS feature which should fix this and other privacy concerns by overriding the DNS settings and encrypting DNS traffic.
Sorry for "derailing" your thread, good luck with it.
P.S: why even ask on XDA for people to verify what has been well established on another forum and by yourself?

That's not the point. The point is that if OxygenOS feeds our devices with a 3rd party DNS server without user knowledge or confirmation is unethical and in many cases illegal.

8.8.8.8 is Google's DNS servers, it had the exact same setting on my Nexus 6. You can easily remove the setting via the modify DNS server setting.
You might want to disable Google's async DNS setting in Chrome or any Chrome based browser too.

Did you find any way to disable this thing?

You'll find it's a Google thing not a OnePlus thing. Google products get really ****ty if they can't get to Google DNS servers. To help ease your mind you can use Private DNS which should send everything through that DNS over TLS server, secondly within DHCP assign a Primary and Secondary DNS which should override Google in the Secondary, lastly if you are running a firewall such as pfSense and not a home router you can setup rules to redirect all external DNS queries to the internal resolver.

In my case i cannot set a secondary DNS via DHCP (because my router has only primary DNS setting available).
Btw, the problem seems related to this setting (https://discourse.pi-hole.net/t/disable-async-dns-resolver-in-google-chrome/9500) which sometimes, for unknown reasons, force Chrome to use secondary DNS, even if primary is fully reachable.

Crazy! Mine is that way too. Thanks for heads up! I changed mine to automatic and now my router controls it and Google's dns is gone! I was wondering why my send and receive on websites was slow since pie. This seems to have resolved it!
