I am trying to install an app to a jailbroken iPhone from PC via USB (using AFC2), for personal research. The app is actually an installer, so it has no UI.
My biggest 2 problems are: I don't know any API to run a command via an USB services, to run the binary after copying.
Then, I installed a LaunchDaemon plist to start my installer, but it seems that the binary is copied with no execution rights (maybe a limitation in AFC2), so the launch daemon fails.
So now I am stucked. Do you have any ideeas?
UPDATE
Thanks to creker I made some steps into achieving my goal. He provided me with several solutions, but I chosen the automatically install DEB via Cydia, since it looks the most simple and elegant method of all.
Nevertheless, I hit some bumps with this method also:
now I am able to succesfully install the .deb file via Cydia; I load the app and a launch daemon in the deb, but the launch daemon is unable to start the app, since installd fails to validate the app, which was fake-signed with ldid (I thought ldid signing is sufficient for running in jailbroken environment); so I guess either I sign it for real or I use a tweak like AppSync, to bypass validation
I also tried the following formula: a launch daemon to launch a bash script, which then starts the app, since I saw that cydia and OpenSSH registers some launch daemons like that, but my script / launch daemon is ignored, so I presume there should be a trick somewhere. Am I missing something here?
Do you have a WiFi? If not, you can use USB tunneling. Then you can SCP your app on a device and install it with SSH (give it persmissions you need and then launch). That's enough for testing. Or you can pack it into debian package with postinst script that will do all the installation. Debian packages can be installed manually through ssh and deb -i command. Or you can copy it into /var/root/Media/Cydia/AutoInstall and it will be installed automatically on device boot.
As for root:wheel, you can do this in your postinst script. The script by default is executed with root permissions. Just set all necessary permissions in it for all your files. If it's a daemon, you can even manually add it to launchd and launch immediatelly.

I have a docker image with a medical data analysis app installed in it. The app works from both gui and console. Normally, in my linux, I run the app from the terminal as
./dsi_studio --action=trk ...
and it works quite smoothly. If you click on this app, it'll try to open a GUI. While I'm trying to use this inside the docker image, it tries to connect to the display in any case (even if I run as shown in the terminal). And, of course, since I didn't do any setup for showing GUI from docker, I get the following error, stating that it couldn't find a display to connect.
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
I don't know why the app is trying to open a display while running in terminal, because it doesn't open a GUI in my linux. I just want to suppress this warning somehow, as if there is a fake display. I don't want to connect my display to docker image, because this image is going to run in batch in an HPC.
So, How can I do this?
You should probably export the DISPLAY environment variable to point to your linux terminal.
Just to test, run
xhost +
in your linux terminal and add
-e DISPLAY=:0.0
to your docker command line
I'm trying to streamline my iOS development builds and read about Docker.
If I understood it right, I could create an image that would include all the dependencies and my fellow devs could just pull it and build inside it.
Point is now, does this also work with Fastlane (which uses the Xcode cli tools I think) and "Docker for Mac"?
Also, I'm using React-Native, which seems to start a second process for bundling the JavaScript that will be included in the native build later and I read Docker only allows one process, is this a problem?
The problem with using Docker is that even if you use Docker for mac, you won't have access to macOS-based images. Docker runs in a lightweight virtual machine called xhyve - at least if you install docker via the Docker for Mac package - that runs Linux on your mac.
Essentially what this means is that your docker container is going to be limited to non-Xcode functionality. Here's what you definitely won't be able to do, at least not without a non-trivial amount of work:
Compile your app's native code
Take screenshots of your app or run your app in the Simulator
Signing the finished app with Apple's codesign
Here's things that you could potentially use your docker container for:
Building the JS code (I assume, since RN should work on Linux)
Uploading your app with iTMSTransporter (i.e. using fastlane's deliver)
Downloading/Creating certificates, provisioning profiles and push certificates (i.e. fastlane's match, cert, pem and sigh)
Working with git
All in all you're probably going to be very limited. Instead, it would be advisable to use things like Gemfile and Brewfile to list all your dependencies, and have a small setup.sh script that runs brew bundle and bundle install to install them on your colleague's machines. You can also set it up to run those during building (with Xcode's script build phases), so that no one can accidentally forget to install something that is needed for the build.
That being said, there is a fastlane docker image that is being worked on here that is also available on the Docker Hub. Note that it has only ever been tested to run the fastlane tests (that don't depend on macOS-only software), so it doesn't actually claim to run fastlane reliably.
I read Docker only allows one process
Docker allows multiple processes, it just doesn't allow more than one main process. If your main process stops everything else and the container stops with it. If you just want to use it to install dependencies so that you can run one-off commands that use them, instead of hosting a long-running service, you can always do that by using docker run:
docker run <repo/image:tag> <your_command>
Or launch an interactive shell into the container:
docker run -it <repo/image:tag> /bin/bash
I would like to silently install chocolatey on a series of test agents, and I'm trying to use a TFS build to do so. I have a build step that uses the "Run Powershell on Remote Machines" task. This in turn invokes the ps1 to install chocolatey, from https://chocolatey.org/install.ps1, and I supply the powershell switches as documented on the chocolatey website:
-NoProfile -InputFormat None -ExecutionPolicy Bypass
When I run the build, I receive this error:
System.Management.Automation.RuntimeException: A command that prompts the user failed because the host program or the command type does not support user interaction. Try a host program that supports user interaction, such as the Windows PowerShell Console or Windows PowerShell ISE, and remove prompt-related commands from command types that do not support user interaction, such as Windows PowerShell workflows. ---> System.Management.Automation.RuntimeException: A command that prompts the user failed because the host program or the command type does not support user interaction. Try a host program that supports user interaction, such as the Windows PowerShell Console or Windows PowerShell ISE, and remove prompt-related commands from command types that do not support user interaction, such as Windows PowerShell workflows.
What am I doing wrong? Seems odd that the chocolatey installer required user interaction, I think the whole point of chocolately was silent installs?
It seems you have wrong settings in task "PowerShell on Target Machines". Follow the steps below:
Create a .ps1 file on the target machine and specify the text below:
Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object
System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
In "PowerShell on Target Machines" task, specify the location of the .ps1 file just created.
Queue the build.
Check the screenshot below:

silent installs?
Typically it goes fully silent, unless there is something (like a proxy) that requires input. It would be best to determine what might be causing the issue by running the install directly on the machine and seeing what happens.
Details
The install.ps1 passes over to chocolateyInstall.ps1, which calls chocolateySetup.psm1.
As you look over that script, you may notice that the install.ps1 uses Write-Output, but that psm1 uses Write-Host in some places. This may or may not cause issues, but it's unlikely given that the script works fine with PowerShell DSC.
So it could be a few things:
Make sure whatever runs that script has Administrator privileges, otherwise you will get an access denied error (unless you specify a different Chocolatey installation location).
Make sure you are not getting hit by needing to put in proxy credentials (which is fixed by the Offline Recommendation below).
Make sure you are not getting hit with not being able to access internet resources (which is also fixed by using offline resources).
It could be something else causing a popup, like needing to install .NET 4.x. Recommend you have the latest .NET Framework in the 4.x series installed prior to installing Chocolatey.
Offline Recommendation
The best recommendation we can give - don't use the internet for any part of this script. If you want reliability, you should have everything internal. That includes the install.ps1 script you are going to use for Chocolatey and the chocolatey.nupkg itself.
Take a read over at https://chocolatey.org/install#completely-offline-install to understand our recommendations.
When any application that uses bash to launch their executables as root, iOS registers the bash script as the main executable instead of the intended executable.
The problem is that I cannot turn off cellular access to these applications because iOS calls the script rather than the applications executable and nothing happens.
I found a partial method that works, but it's not practical because the application looses root capabilities, but it will allow the setting's app to disable cellular data for the application;
Remove the bash script,
Rename the apps main executable to the bash scrips name,
Reboot.
Can I do anything to solve this?
Thanks, Jason.
I would like to run a script on a device that I have established an SSH session into. However, the script is on my local Windows machine.
For my experiment, I have:
A python script on my local machine (Windows)
A jailbroken iOS device that I can SSH into using putty
I want to run the python script, that's located on my windows machine, on my jailbroken device.
Is this possible?
I know on a Mac, you can actually use the terminal to do just that and it would look something like this.
python [pythonfile].py [parameters] [target device]
The reason why I can't just run the python script on my device is because I can't install python on that device (at least it isn't on Cydia). Plus, I don't want to pay for an app that executes it.
Let me know if you have any suggestions, thanks.
Have you tried this libssh2-for-iOS. Its an open source library which does exactly the same thing you are looking for.
