Re: Permission denied!

[Douglas Santillan A.]

Remount first
adb remount

If still fails, grant perms
adb shell chmod 777 /path
Once done restore perms
adb shell chmid 755 /path

Hey folks I'm trying to push a compiled VNC server binary into Android x86. I set up an ADB connection between my Android x86 from one machine to my main development machine (ubuntu). I can instal APK's no problem. But when I tried to push the binary files it said "Permission denied" ... do you folks know how to fix :(

~/Desktop/android-sdk-linux/platform-tools# adb push androidvncserver /data/local/

failed to copy 'androidvncserver' to '/data/local//androidvncserver': Permission denied

adb shell "su chmod 777 /path"

Thank you so much for your advice but sadly didn't work :( (still permission denied when running $adb push androidvncserver /data/local)

ran on Ubuntu machine with ADB connection to Android x86.

Sorry, I think that there is something wrong with the command syntax provided try

adb shell su -C "chown 777 /path"

If fail try these steps

adb shell
On android promt
su
On super user
chmod 777 /path
exit
On android promt
exit

Upload files, then restore perms

No passwd entry for user 'adb'

Really appreciate you helping me out and trying to figure this out

[Douglas Santillan A.]

Just give perns to the binary 755 should do

adb shell su -c "chmod 755 path/file"

First number is super user
Second system
Third user

4 gives read
2 write
1 exec

7= write+read+exec
5= read+exec

PERFECT!!! Your the best!

 the command

worked cause I pushed it and it went through (below). Last quick question. When I try running it it gives me a same error that permission is denied :/ do I have to make it executable and if so how :))

I don't know why are you placing this executable in data. Bins should go in /system/bin or /system/xbin so they are accesible to the system

Thing is, you need to remount system for write, then push to /system/bin give owner (chown 0.0 or root.rooot) then perns (chmod 755). Then remount read only

Data is mounted read/write
System is usually just read

I am away from my desktop. I will send you details later.

It was just the instructions for the Android vnc server (bottom of this link: https://github.com/LibVNC/libvncserver/blob/master/examples/android/README) and their main link: https://code.google.com/p/android-vnc-server/wiki/README

Also other folks put it in /data: https://code.google.com/p/android-vnc-server/wiki/README (comment: "Comment by Ryan.Bee...@gmail.com, Dec 4, 2009")

So you think I should put it in /system/bin?

So same procedure as before right but instead of "/data/local" I should do it in "/system/bin"

Please confirm this is an executable for android-x86.
Issue the commands in your linux host:

file androidvncserver
ldd androidvncserver

(I suspect it's an arm executable)
