DNS proxy for Android 4.3+

dnsproxy2's Issues

use ndc to set dns

on android 4.3 and 4.4 run command bellow:
ndc resolver setifdns wlan0 "" 208.67.222.222 208.67.220.220

res_query: send error

DNS resolution works correctly when calling dnsproxy2 -l directly:

;; res_setoptions("debug", "env")..
;;	debug
;; res_nquerydomain(google.fr, <Nil>, 1, 1)
;; res_query(google.fr, 1, 1)
;; res_nmkquery(QUERY, google.fr, IN, A)
;; res_send()
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 27940
;; flags: rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;;	google.fr, type = A, class = IN
;; Querying server (# 1) address = 8.8.8.8
;; new DG socket
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 27940
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
;;	google.fr, type = A, class = IN
google.fr.		4m59s IN A	216.58.209.227
216.58.209.227

But if fails when used in proxy mode:

;; res_nquerydomain(google.fr, <Nil>, 1, 1)
;; res_query(google.fr, 1, 1)
;; res_nmkquery(QUERY, google.fr, IN, A)
;; res_send()
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 36674
;; flags: rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;;	google.fr, type = A, class = IN
;; res_query: send error

How can this dns proxy project work on the phones below android 4.3?

Binary files would be useful to common people

Really great project, i was just wondering if you could put a dist/ folder with the latest built commit.
Would be very useful for people experimenting with the binary, or someone that wants to create a GUI for it!

CM13: only position independent executables (PIE) are supported.

When trying to run dnsproxy2 on CM13:
error: only position independent executables (PIE) are supported.

wishlist: put it on fdroid

Hi,
I found dnsproxy2 coming from https://www.kuketz-blog.de/f-droid-und-afwall-android-ohne-google-teil4/ I'm trying to make afwall+ see all the dns requests. However, I'm not technical enough to compile and package Android apps and automate the installation of security fixed whenever github changes anything. Would you please put Dnsproxy2 on Fdroid, for a wider audience?
Thank you.

Another dns proxy for Android 4.3+

There is another dns proxy for Android 4.3+. It's supports running standalone or JNI built-in Android application. and select dns servers by policy (client uid to dns servers).

Thank you patch of setfsuid. ;)
