Small knowledge, big challenge! This article is participating in the creation activity of “Essential Tips for Programmers”.

preface

One day when you tweak tweak to 100 iPhone machines you manage, the usual way of making package install, dpkg-i, becomes inefficient. Tweak to batch deploy solutions on devices by setting up a private Cydia source

~/ Cydia -m SimpleHTTPServer 8088

From cydia add corresponding source (http://192.168.2.189:8088/)

I. Cydia source server setup

Assuming our source URL address is 192.168.2.189/cydia, for a local cydia directory, the structure is as follows

Cydia/ --Release repo description file --Packages repO package manifest -- packs.gz Package manifest of the repo -- packs.bz2 Package manifest of the repo -- cydiaicon. PNG --debs/ actual package file --xxxx1.deb --xxxx2.debCopy the code

To build a software source, you must have at least two Release and Packages files, see auxiliary scripts

Download.csdn.net/download/u0…

Core building steps:

Create a repository for deb packages
Enable HTTPServer: ~/cydia executionpython -m SimpleHTTPServer 8088
The corresponding source is added to the cydia in order to download the update deb package (http://192.168.2.189:8088/)

1.1 Use Bzip2 to generate a file format that Cydia can recognize and put into a specific directory as a repository for download

Making scripts to download

Download.csdn.net/download/u0…

HTTP / 1.1 PNG" 404 -
Copy the code

1.2 open the HTTPServer

python -m SimpleHTTPServer 8088

Tests can be used, this command simply opening a HTTPServer ~ / cydia python SimpleHTTPServer 8088 – m running under the corresponding to the original address: http://192.168.2.189:8088/cydia

1.3 Add your own source address to Cyida

Let’s start by looking at the configuration file that holds the source address in Cyida

iPhone:~ root# cat /var/mobile/Library/Caches/com.saurik.Cydia/sources.listDeb http://apt.saurik.com/ ios 1144.17 / main deb https://build.frida.re/ / deb http://cydia.zodttd.com/repo/cydia/ Stable main deb http://repo666.ultrasn0w.com/ / deb http://192.168.2.185/cydia/ / deb http://192.168.2.69:8088/ /Copy the code

Wl. list can be created in /etc/apt/sources.list.d or added directly to cydia.list

 echo -e 'deb http://apt.saurik.com/ ios/1348.22 main \n' >  /private/etc/apt/sources.list.d/cydia.list

Copy the code

Method 1: Add built-in sources with one line of command: Use the prints script to modify sources.list to add source addresses.

Let ordinary people do not know how to delete our source/private/etc/apt/sources list. D/wl. List;

Add the built-in source using the preinst script from the initial deb installation, and then deploy a new machine without adding multiple sources.

# Add in preinst script:
function kncydia {
    echo "[Add your source address to Cyida]"
        # install.exec "echo -e '127.0.0.1 localhost \n192.168.2.107 xx.com' > /etc/hosts"
      echo -e 'deb http://192.168.2.69:8088/ /' > /private/etc/apt/sources.list.d/wl.listThe #-e argument is used to use the newline character \n
}


Copy the code

Check whether the modification is successful

/private/etc/apt/sources.list.d root# cat wl.listDeb http://192.168.2.69:8088/ / deb http://192.168.2.185/cydia/ /Copy the code

Mode 2: Manually add the source address in Cydia APP

Manually adding is equivalent to modifying the following files

/private/etc/apt/sources.list.d/cydia.list -> /var/mobile/Library/Caches/com.saurik.Cydia/sources.list

II. Knowledge supplement

2.1 Description of File directory Functions

Let’s review the directory structure of Cydia_repo

Deb source directory cydia is essentially require specific structure - | - debs - *. Deb | - Packages: DPKG -- scanpackages debs/dev/null > Packages; Packages files contained in the source of each packet of information, including the file path, size, dependence, architecture and calibration information | -- Packages..bz2: by compressed Packages files, command line: bzip2 Packages; | -- Packages. Gz | - Release: it is a plain text file, is used to describe the current source of information; This information is in the source list Cydia and Tweak search list | - the GPG: Package Signatures, the from our Release file. This file will be downloaded by the clients first and then is used to verify the validity of the Release file. gpg -abs -o Release.gpg Release Bz2 and debs are required. Other files are optional.Copy the code

Release

Cydia source configuration file, the client by downloading this file to read Cydia source information;

There is little to change to the Release file, just prepare the deb file and generate Packages with dpkg-scanpackage

Packages

1) Deb index file, save each DEB control file information, and each DEB file information.

2) This directory is generated by dpkg-scanpackages debs /dev/null > Packages

Packages.bz2

Compressed from Packages files, command line: bzip2 Packages

CydiaIcon.png

an icon named “CydiaIcon.png” in your root dir so the user finds your repo at a glance.

2.2 Deb package execution script

Execute scripts before debian/ Preinst installation
Run scripts after Debian/Postinst is installed
Debian/PRERm Scripts are executed before uninstallation
Run scripts after debian/ POstrm is uninstalled

2.3 Two distribution modes of tweak

Package into deb format for batch installation on jailbroken devices

Package the patch as ipA directly using the developer’s own certificate/enterprise certificate so it can be installed without jailbreaking.

cydia

Developed by Jay Freeman (Saurik) and his company to install and manage third-party software and plug-ins on jailbroken devices. It ports the package manager DPKG on Debian and provides a graphical front end for ordinary users. Cydia also has a Cydia Store, which offers paid third-party apps.

CydiaSubstrate

IOS7 was also previously called MobileSubstrate, which was also developed by Saurik. Cydia Substrate consists of 3 major components: MobileHooker, MobileLoader and safe mode.

Electra

Tweak developer CoolStar developed the Electra jailbreak tool based on Async_awake and an open source alternative to CydiaSubstrate: Substitute developed by Comex. Supports all iOS devices from iOS11.0 to iOS 11.1.2

III. Other examples

Remove the built-in source, leaving only apt.saurik.com/

 iPhone:~ root# find / -mmin -1
     echo -e 'deb http://apt.saurik.com/ ios/1348.22 main \n' >  /private/etc/apt/sources.list.d/cydia.list
     echo -e 'deb http://apt.saurik.com/ ios/1348.22 main \n' >  /var/mobile/Library/Caches/com.saurik.Cydia/sources.list

# deb http://apt.saurik.com/ ios/1348.22 main
     echo -e 'deb http://apt.saurik.com/ ios/1348.22 main \n' >  /private/var/mobile/Library/Caches/com.saurik.Cydia/sources.list
Copy the code

Clear V_P_N garbage log

     echo "" > /private/var/log/ppp.log

Copy the code
