[Q] Running DNS Server on Android device - Android Q&A, Help & Troubleshooting

Hi all,
is it possible to run an internal DNS server on Android? I am looking for a solution similar to bind9 on Linux (e.g., h**p://ubuntuforums.org/showthread.php?t=236093) that allows to define DNS zones, i.e., all DNS requests are first of all redirected to 127.0.0.1 and then forwarded based on the predefined DNS zones.
Unfortunately, I didn't find aything about this, so I was wondering if it's possible at all in Android?
Thanks,
Chris

Android - SIP API and SIP server/account

I have just found this example: SipDemo and I have noticed you need, of course, to add the username, password and domain of the used SIP server.
The example shows a walkietalkie, but I would like to have a normal phone call kind of thing.
I was wondering whether there are free and reliable servers for SIP communications.
What I would like to have is just 1 account and every user of mine should be able to call each other in that way.
I am considering both:
-Hosting my own SIP server on my side;
-Using an already existent FREE server.
Probably each user should have its own account, then I believe the easiest way is to have the server on my side. Is that correct?
Thanks in advance.

[Q] Security question regarding Ad Blocking programs

Hi Everyone,
I have a question regarding these Ad Blocking programs. I see that they primarily work by adding entries in the Hosts file for IP resolution (usually the loopback address 127.0.0.1) for known Ad addresses. So my question is this... Is it possible for hackers to produce a fake (or partially legit) product that could be used for Phishing? They could inject IP addresses for banking, ecommerce, etc., websites to be directed to their fake sites.
Any thoughts?
Thanks!

You mean do something like redirect Wells Fargo to a copycat site to phish usernames, passwords, CC#'s etc? It's certainly possible. It'd be a pretty limited audience hack though. You'd still probably do better just sending a mass email.
I spoke with the author of Adfree and his program implements checks on the downloaded host files to ensure they only point to 127.0.0.1 unless specified in the options.

Click to expand...
Click to collapse
Yeah... I thought that the easy way to rest assured was to go through the hosts files to be sure all the entries point to the loopback address...
Thanks!!

[Q] Servers Ultimate APP questions

Some of you may already know about this app which lets you turn your Android device into one of many different types of servers. I am very interested in this, but am not sure of which type of server I should be using.
Could someone knowledgeable give a brief description of what each type of server would be used for?
I am personally wanting to run this on my HTC EVO 4G at home so that I can access things at any time from any computer. I am not sure which server that would be though.
It runs:
DLNA
DNS
Dynamic DNS updater
Email Server
FTP server
IRC Server
Proxy Server
SMS Gateway
Socks Server
SSH Server
Telnet Server
Test Server
Time Server
Web Server
WebDAV Server
Thanks for the info.

[Q] Hotspot force redirect to Local Server

I got this crazy idea that I don't know is possible or not... what I want to do is set up my phone as wifi access point, then allow people to connect to it, but handle all incoming http traffic myself.
So:
Create a server (with KWS - Android web server)
client can connect to the phone
when client tries to open an http connection to any random server, this has to be intercepted by my app and handled by a local web server
Anyone knows any android app to do this ?
What you are talking about is a captive portal.
I made a simple app for this purpose. If you are a developer, I need your help to improve the app. For downloading the app and source code check this thread https://forum.xda-developers.com/android/general/guide-setup-fake-captive-portal-android-t4011689

Private DNS question

Hi,
I use the native Private DNS (DoT, DNS-over-TLS) on Android 9 for a while with my company DNS server. Private DNS (DoT or DoH) have no authentication option and the admins are running amok because the unwanted traffic from anywhere. The DNS should be the only DNS source for the devices outside the company and not a free service. DoT and DoH are faced by nginx for TLS termination and capable to make client certificate authentication (is now active on DoH). So the question:
Can I (and when - how) assign a client certificate to the native DoT client on android 9 (or following)?
Thanks
