CIFS Manager on CM 7

Here is what I've tried:
1. Settings -> about tablet to get kernel version: 2.6.32.39-cyanogenmod [email protected] #1
2. Go to http://droidbasement.com/db-blog/ and find the kernel for gTab. There are several one, I just picked one with Gingerbread and downloaded
lib-2632.39_gb.tar.gz
Unpack on put cifs.ko under /system/lib/modules
3. Install CIFS Manger
4. Run CIFS Manager, add the share
5. If there is problem mount it in rw mode, use option "rw,noperm" (thanks, rajeevvp)
The share is successfully mounted.
Thanks!

The only issue I have is that it can't seem to mount a share in read-write mode even though it's shared with write permission. Does anyone know how to fix it?

After pushing the cifs module to the tablet you need to add an chmod and then you also need a insmod line every time you want to use it (at least after following a reboot).
Go back and read the instructions on droid basement. He has the details of the steps following loading the cifs.ko.
Good luck.

CIFS manager already loads the module fine. Are you saying in order to mount in rw mode, it needs permission on cifs.ko file?

No, you don't.
CIFS Manager should have an option to do a read-write mount.
Otherwise, you can try changing the mounting back into read-write mode:
Code:
$ su
# /system/xbin/mount -w -o remount /CIFS/PATH
Replace, /CIFS/PATH with the directory you provided to CIFS Manager.
Also, understand my cautions, as mentioned in the other thread, about mixing and matching kernels and kernel modules. I would suggest that you also install the kernel that goes with the module file you downloaded--ie. get the one in the same blog post.

Appreciate your advice on not mixing kernel and modules. I could not tell which exact build CM 7 uses so I had to pick one. When I get more experienced with Android, I may start changing kernels.
Doesn't CIFS uses rw mount by default? If not, what's the option? rw? I've tried that as well.
If I change the system file to mount it by default, I'd have to save the password on the command line, right? Will wireless be ready at that time? And if server or wireless is not ready at the time, I'd need to manually remount with some tool, do I?
Thanks!

I wanted to help you with this earlier but been sidetracked. I hope this helps

Yes, by default it should be mounted read-write. If, for some reason, it gets mounted read-only, you can use the remount command I gave earlier to make the mount read-write again.
But, there could be other reasons for you not being able to write to the share directory. Permission and UID/GID mismatches could be one reason. Try adding the "noperm" flag to tell Linux not to check permissions locally ie. do the permission checking only on Windows:
Code:
/system/xbin/mount -t cifs //SERVER-IP-ADDRESS/SHARENAME /some/path -o rw,noperm,domain=DOMAIN,username=USER.NAME,password=PASSWORD
If I change the system file to mount it by default, I'd have to save the password on the command line, right? Will wireless be ready at that time? And if server or wireless is not ready at the time, I'd need to manually remount with some tool, do I?
Click to expand...

Which system file? If you mean /etc/fstab, then that file does not exist on Android.
CIFS Manager (I haven't used it) should have an option to let you store the password securely. On normal Unix systems, the mount command accepts a "credentials=/some/file.txt" option which can be used in place of the "domain=XXX,username=YYY" options when mounting. Unfortunately, the mount command on the gTablet does not understand that option--I checked: you have to do it the old-fashioned way. You can't even skip the "password=" bit. On Unix, if you skip that, the mount command will prompt you for the password.
The solution, if you don't use CIFS Manager, is to place all the commands--the insmod and the mount--into a shell-script and give it 700 permissions. That way only the owner can see what's inside it and you can run the script after the wireless has come up.

noperm does the trick. Will update first post.

Could you explain the exact process for doing this from a terminal emulator. My main hold up is the /system directory being read only, so I can't copy the module (CIFS.KO in this case) to that directory.

You don't need to put cifs.ko into /system. If CIFS Manager asks for the path to a cifs.ko file, then you can put the file anywhere you want.

I have a new problem. There seems to be a limit on the file size. I have a 3 GB file shows up as 28 KB. Does anyone have success with large file? Thanks

I tried your instruction... there are two problems...(my rom is also cm7.0.3)
1. I can't put the cifs.ko into /system/lib/modules~ it seems that it is forbid to copy some files into system folder...
2. so I tried to put the cifs.ko in the /mnt/cifs.ko, and made the related setting in cifs manager(path to cifs.ko), then i mounted, but it showed that:"no route to host"
but i am sure that my ip and password is correct... so is there anyone know how to solve this problem?

I used Root Explorer. I am sure there are other means to put it under /system. I am not sure if that's necessary

I literally just went through this today. Download Terminal Emulator (free on the market).
PS: Don't type the '#' sign below.
#su
#/system/xbin/mount -w -o remount /system
#cp /SDCARD/cifs.ko /system/lib/modules/2.6.32.41-cyanogenmod/
#/system/xbin/mount -r -o remount /system
Then, just add the path /system/lib/modules/2.6.32.41-cyanogenmod/ into CIFS Manager. Should be all set.

File size limits depend on the underlying filesystem.
I tried the following command on an external NTFS formatted USB HDD connected to a Linux desktop mounted on the gTablet at /mnt/usbdisk via CIFS, and had no problems.
Code:
# ls -l /mnt/usbdisk/rvp/bak/hda3.img
-rw-rw-rw- 1 root root 8011422720 Apr 17 2010 /mnt/usbdisk/rvp/bak/hda3.img
# dd if=/mnt/usbdisk/rvp/bak/hda3.img of=/dev/null bs=1M skip=7500
140+1 records in
140+1 records out
147102720 bytes (140.3MB) copied, 150.135761 seconds, 956.8KB/s
The command skips the initial 7.5 GB of a 8,011,422,720 byte file and reads the rest (~140 MB).

I had the same issue, but I found the guide on abettergeek which helped me fix it. Turns out the problem is that the mount point created by Cifs Manager doesn't have execute permissions.
I don't have enough seniority to post the link, but it's a recent post on abettergeek.com. If someone with enough seniority wants to paste it, some others may find it extremely helpful.

ByteWrencher

Pls, where I can put "rw,noperm" in cifs manager? I tried in module path as:
/system/lib/modules/slow-work.ko:/system/lib/modules/cifs.ko rw,noperm
And:
/system/lib/modules/slow-work.ko:/system/lib/modules/cifs.ko:rw,noperm
But still don't working as rw.

[GUIDE/MOD] DNSCrypt for AArch64 (ZIP) (2016/03/17)

NOT SYSTEMLESS!
This writes to system, so systemless master race stay away.
Someone wanna make a Magisk version?
Instructions:
0. Download zip below and place inside internal storage.
1. Boot to TWRP.
2. Mount>System
3. Flash zip
4. Boot to Android and open a terminal emulator
5. Run dnscrypt enable. You probably have to do this every reboot.
Changing resolver:
Edit /system/etc/init.d/99dnscrypt. There's a line RESOLVER_NAME, change it to a suitable one from here under Name. I suggest you ping every server geographically nearby and go with the lowest ping.
Changing DNS server:
On Nexus 5X at least, use a Terminal Emulator and run
Code:
setprop net.dns1 127.0.0.1:53
Self-compile guide:
Requirements:
Linux computer (x86_64)
Android NDK (r12b is the newest so far, get the 64-bit one)
libsodium
dnscrypt-proxy
Here's how I did it:
1. Extract the NDK (unzip android-ndk-rXXb.zip )
2. Run
Code:
export ANDROID_NDK_HOME=<NDK Location>
3. Extract libsodium and dnscrypt-proxy.
4. Enter the folder of libsodium/dist-build, then edit android-build.sh such that NDK_PLATFORM:-android-16 becomes NDK_PLATFORM:-android-24. Then modify android-armv8-a.sh and add
Code:
-mtune=cortex-a57.cortex-a53 -mcpu=cortex-a57.cortex-a53
to the end of CFLAGS.
5. Return to libsodium root folder (cd ..) and do ./autogen.sh then ./dist-build/android-armv8-a.sh. When the script finishes it will tell you where the output is.
6. (Optional) Run android-toolchain-armv8-a/aarch64-linux-android/bin/strip on the output .so (typically in libsodium-android-armv8-a/lib/libsodium.so)
7. Now we do
Code:
export SODIUM_ANDROID_PREFIX=<libsodium output>
8. Enter the folder of dnscrypt, do the same modifications to dnscrypt's dist-builds. Again, do ./autogen.sh and ./dist-build/android-armv8-a.sh.
9. Now you have a fresh compilation of AArch64 dnscrypt-proxy!
It's usually dnscrypt-proxy-android-armv8-a.zip
10. Finally, we need to edit the zip file and rename the /system/lib folder to lib64, and change references in updater-script and /system/addon.d/75-dnscrypt.sh.
11. (Optional) Add --ephemeral-keys to 99dnscrypt for extra security.
Credits:
qwerty12 for the basic instructions
Changelog:
02/19: Updated libsodium (1.0.8->master) and dnscrypt-proxy(01/27 master->master)
03/17: Pulled freshest code from masters, compiled with NDK r11b and platform android-23
09/26: Latest stable branch of libsodium and master of dnscrypt. Compilation target now android-24. Compiled with NDK r12b
Changes to both dnscrypt-proxy and libsodium:
dist-build/android-build.sh:
Code:
NDK_PLATFORM:-android-16 to NDK_PLATFORM:-android-24
dist-build/android-arm-v8-a.sh:
Code:
Appended:
-mtune=cortex-a57.cortex-a53 -mcpu=cortex-a57.cortex-a53
to end of CFLAGS

That's true, but at the other side we trust random flashable zips for roms, mods etc from XDA
Thanks for the upload will take a look
Edit: well it works but in DNSManager for example it shows greyed out "Enable DnsCrypt"
dnsleaktest.com shows dnscrypt works though

This works only on 64-bit devices. For 32-bit devices, a download is provided here.
Yes, this is a flashable zip. However, DNS needs to be changed manually such as through DNS Manager because iptables doesn't entirely work.

Any major changes with 4/6? Thanks for updating this BTW.

For automatic execution, you can create a script in /system/su.d or /system/addon.d I guess.

Questions for disable verity

Hello,
I have rooted my pixel 3 by using Magisk,
my version is still Android pie,
it has successfully rooted but then when I type "adb root" it returns adbd cannot run as root in production builds,
I found out it might because I need to disable the verity, but when I type adb disable-verity it shows "verity cannot be disabled/enabled - USER build",
I have tried to follow the steps from https://android.stackexchange.com/q...dm-verity-on-android-with-user-build-type-rom but I don't quite understand how to do it,
I was wondering if anyone have more specific steps that will be able to disable the verity.
Thanks!

As far as I know you cannot do it in 10. I have never updated and tried, but that is what I have heard. There is no way to modify system except systemlessly with magisk modules. What exactly are you trying to do, might help get more suggestions if you tell us.

I am trying to run python script on the phone, so I have found this website https://medium.com/swlh/python-on-android-root-4aa56f22070a
and I was trying to follow the step to install python on the phone, but I am stuck at the adb remount command step.
It shows that I need to type adb root, but when I typed adb root it shows "adbd cannot run as root in production builds",
and I have try mount -o rw,remount /system, it gave me error "mount: '/system' not in /proc/mounts".
I checked mount and for some reason it shows system_root instead of system for "/sbin/.magisk/block/system_root on /sbin/.magisk/mirror/system_root type ext4 (ro,seclabel,relatime,block_validity,delalloc,barrier,user_xattr)", so I did some research and found out that I need to disable the verity, but when I tried to disable it it gave me the error which is "verity cannot be disabled/enabled - USER build".

I checked mount and for some reason it shows system_root instead of system for "/sbin/.magisk/block/system_root on /sbin/.magisk/mirror/system_root type ext4 (ro,seclabel,relatime,block_validity,delalloc,barrier,user_xattr)", so I did some research and found out that I need to disable the verity, but when I tried to disable it it gave me the error which is "verity cannot be disabled/enabled - USER build".

System partition is under /system_root on Pie. I wonder if you could create a magisk module to install the app systemlessly.

Hi,
So now I am trying to unpack the boot.img file that I downloaded from google firmware website in order to try the method that provided by https://android.stackexchange.com/q...dm-verity-on-android-with-user-build-type-rom.
But I was wondering instead of editing boot.img, should I just edit the magisk_patched.img?
Thanks!

You are going to need root so better to modify the magisk boot image.

Hello,
Thank you for your respond!
Do I need to modify boot.img as well?
Or just the magisk_patched.img?
Thank you!

I think there is a way to disable verity before installing the magisk boot img, but you would have to look at the magisk github information.

Sounds good!
Thanks for your advice!
Beside that I was wondering if you know that is there anyway we can access the battery data through abd command?
I know that we can gather cpu frequency info, but I am not sure if we can get the battery data as well.
Thanks in advance!

Maybe check this thread about battery

"No such file or directory" if tried run binary file in TWRP

I need to run a binary file, dalvikvm which located in /system/bin from TWRP terminal, but no matter what, it says, "No such file or directory found", and then I found that this is link file located another directory, I cd'd there and tried, but still the same result
I can be able to run the same file in Termux without any issues
Can anybody please help me on this?
Thanks

Hi, I think you need to mount the system partition before being able to access it. It's not mounted by default on TWRP, but when the phone is on it is (otherwise Android wouldn't work)
If you need help on how to mount partitions on TWRP, ring me (or google it, it's actually pretty simple)

Thanks for replying, it wasn't mounted at first, so I had mounted, still it didn't work, while some of the files in bin do work, some don't.
Then I copied the file to /sdcard and /tmp, and tried execute from these folders, still
Well, if when you're free, can you confirm if it's running on yours?
File: /system/bin/dalvikvm
Thanks once again

I didn't found it inside, but it may be because I'm not rooted.
While searching around I've found this :

I looked into it.
I had no opt folder in root directory. So I made one, and moved dalvikvm to there and tried execute this time, it said permission denied, so I gave it chmod 755. But after that, it says "there no such file or directory".
Well, do you telegram account, so I could contact you there.
Thanks

This is really curious, tbh I'm not an expert around that subject, idk what's wrong with this binary...
Hopefully someone who knows more may help you with that. Have a nice day

This is because the binary you are trying to execute was compiled to run in the Android context, but you're trying to execute it in the TWRP one. Each binary has a path to a linker used during execution. The problem is that it refers to a linker that doesn't exist in TWRP.
Suppose we want to execte a binary file and obviously we can't:
Bash:
x00h:/ # /system/bin/awk
/sbin/sh: /system/bin/awk: No such file or directory
Let's take a look to its linker:
Bash:
x00h:/ # strings /system/bin/awk | head -n 1
/system/bin/linker64
Then, you will actually discover that it's sym linked to a linker that is available only when Android is running:
Bash:
x00h:/ # ls -ald /system/bin/linker64
lrwxr-xr-x 1 root shell 38 2009-01-01 00:00 /system/bin/linker64 -> /apex/com.android.runtime/bin/linker64
Since TWRP comes with its linker in /sbin/linker64, we can sym link it to /system/bin/linker64.
So, the hack:
Bash:
x00h:/ # mkdir -p /apex/com.android.runtime/bin/
x00h:/ # ln -s /sbin/linker /apex/com.android.runtime/bin/linker
x00h:/ # ln -s /sbin/linker64 /apex/com.android.runtime/bin/linker64
Retry, and it works:
Bash:
x00h:/ # /system/bin/awk
usage: /system/bin/awk [-F fs] [-v var=value] [-f progfile | 'prog'] [file ...]
Pray to God the TWRP's linker will be compatible and do the job (most binaries works fine), but sometimes you may get CANNOT LINK EXECUTABLE.

Question How to do run root as Pixel 6A?

adb root
I have already tried the following command, but it says:
adbd cannot run as root in production builds

Uh.. What are you trying to do?
Are you trying to emulate a Pixel 6a on your computer, or do you want to have root privileges on your device?

I want to have write permission on /system/bin and /system/xbin, this is for the purpose of me importing nano into the devices. My main goal is to have a bashrc alias and and make it easy for me to edit files in the system.

You'll have to look into rooting then. I suggest you use Magisk. There are many guides on xda (specifically for this device too).

Even magisk won't overcome that error, because at the end of the day, it is a production build.
But that doesn't mean you can't use root! You just can't call "adb root".
Code:
adb shell
$ su
# <-- do stuff as root
# exit
$

Just to be clear, even if you have root, you can't easily write to the system partition. The system partition is mounted as read-only and to get around that you'd need several steps like a modified super partition, and potentially have verity/verification disabled.
Your best bet you be to use Magisk, and either use the Magisk mirror partitions to add nano, or use the Magisk nano module (https://github.com/Magisk-Modules-Repo/nano-ndk)

You can use Termux, or any other terminal emulator, type 'su', allow superuser privileges, and do stuff as root.

Btw, how do I install nano-ndk? There is no release on the GitHub page and when I try to download the .zip file and install, it say fail.
[ Error writing /etc/mkshrc: Read-only file system ]
How do I go about editing this when it is a read only file system
Ok I have successfully added nano, now how do I edit the following file to add alias

You never really mentioned where you suggest them use that bit of code you provided, nor have you suggested they use a terminal emulator (where they can obtain root privileges), but alright.

Terminal emulator application is irrelevant. OP was asking about ADB specifically.

hope you are aware that if you modify /system you can't ota update anymore

You CAN...but this can only be done in engineering and debug builds.
adb root restarts adbd with root permissions.
There is a way around this; use an elevated shell to write ro.debuggable=1 to /system/build.prop, /system/default.prop, or /data/local.prop
If you want adb shell to automatically start with root, add ro.secure=0
