Mac Remote login to an iOS device

Welcome to follow the official wechat account: FSA Full stack action 👋

Install OpenSSH

The premise of this article is that the device has been jailbroken!

Secure Shell (SSH) is a security protocol based on the application layer. It is used for encrypted login between computers and provides a Secure transmission environment for network services on insecure networks

Search for OpenSSH in Cydia and install it

account

Root: indicates the account with the highest permission. $HOME is /var/root

• Account:root
• Password:alpine

Changing the Login Password

1. The loginrootaccount
2. Modify therootPassword of the account, terminal input:passwd

Remote login

Method 1: Account password

Go to the “Settings” -> “Wi-Fi” page of your iOS device, find the network you are connected to, and check its IP address

If the IP address 192.168.10.104 is displayed in the preceding figure, enter:

SSH [email protected]Copy the code

Enter the password: alpine

Method 2: Password-free login

Compared with method 1, you do not need to ask for a password every time you connect to SSH

1. Generate a secret key pair

ssh-keygen -t rsa

#By default, OpenSSH generates an RSA key. The -t parameter is the specified key type
#So the above command can omit the -t parameter: ssh-keygen
Copy the code

2. Upload the public key toiOSequipment

Mode 1: Automatic (recommended)

Run the following command and enter the password

SSH - copy - id [email protected]Copy the code

Method 2: Manual

#This method overwrites the authorized_keys file directlySCP ~ /. SSH/id_rsa. Pub [email protected]: / var/root /. SSH/authorized_keysCopy the code

Since the authorized_keys file will be overwritten, it is best to upload id_Rsa. pub to the device and then append to authorized_keys

#Upload the public key to root's home directorySCP ~ /. SSH/id_rsa. Pub [email protected]: ~
#Logging In to an iOS DeviceSSH [email protected]
#Append content to authorized_keys
cat ~/id_rsa.pub >> ~/.ssh/authorized_keys

#Example Remove the uploaded public key
rm ~/id_rsa.pub
Copy the code

Now log in again and you won’t need to enter your password

3. Precautions

If the /var/root/. SSH directory does not exist on the iOS device, the following error message is displayed

scp: /var/root/.ssh/authorized_keys: No such file or directory
Copy the code

You need to log in to the device to create the directory

xunfengteki-iPad:~ root# cd /var/root/
xunfengteki-iPad:~ root# mkdir .ssh
Copy the code

If you still need to enter the password after the configuration, it may be that the file permissions are insufficient. You need to log in to the iOS device and run the following command to change the permissions on the files or directories

chmod 755 ~
#Set the.ssh directory permission
chmod 755 ~/.ssh
#Set the authorized_keys permission
chmod 644 ~/.ssh/authorized_keys
Copy the code

USB connected device

All of the above mentioned devices are connected through Wi-Fi, which has a big drawback, that is, when the network is not smooth, it will be slow. In order to ensure the transmission speed, you can solve this problem through USB connection

1, install,usbmuxd

brew install usbmuxd
Copy the code

2. Port mapping

Mapping local port 2222 to remote port 22

Iproxy 2222 22 [Device UDID]Copy the code

If multiple iOS devices are connected to the same Mac, add the DEVICE UDID to the end of the command. If there is only one iOS device, omit the UDID

3. Connect the device

SSH -p 2222 [email protected]Copy the code

Encapsulating common commands

Shuttle: simple terminal command shortcut menu, liverpoolfc.tv: fitztrev. Making. IO/Shuttle /

"IOS" : [{" iPhone USB connection ": [{" CMD" : "iproxy 2222 22", "inTerminal" : "new", "name" : "1. USB port mapping SSH"}, {" CMD ": "SSH root@localhost -p 2222", "inTerminal": "new", "name": "2. Connect to iPhone"}]}]Copy the code

Effect:

Now just click iOS -> USB to connect iPhone under 1.USB maps SSH port and 2. Connect iPhone, you can quickly use USB to connect our iOS devices, improve efficiency.

Chinese problem

By default, iOS terminals do not support Chinese input and display. When you enter Chinese, you will automatically delete all the current input content.

Solution: Create an.inputrc file in your home directory

touch ~/.inputrc
Copy the code

Contents of the document:

Set convert-meta off set output-meta on set meta-flag on set input-meta onCopy the code

If you want to edit file content on a terminal on an iOS device, search for Vi IMproved in Cydia and install it

After the installation is complete, enter:

vi ~/.inputrc
Copy the code

Press I to switch to the input mode, paste the content of the above file, press Esc to switch to the last mode, enter :wq, and press Enter to save and exit.

For example, I created a test. TXT, which shows \346\265\213\350\257\225.txt

Solution: search by Cydia Locale Profiles can be installed in utf-8 and source BigBoss:http://apt.thebigboss.org/repofiles/cydia/ (software)

Exit the iOS terminal at this time, but also re-enter the solution!

Click the file system content at the bottom of the details page

As you can see, the plugin installed the Chinese language package in /usr/share/locale and created localeutf8.sh in /etc/profile.d/, setting the current language to en_us.utf-8

xunfengtekiiPhone:~ root# cat /etc/profile.d/localeutf8.sh
export LANG="en_US.UTF-8"
Copy the code
