SUDO-iOS FTP-卡住

Question

I have a script for MobileTerminal in iOS that requires su, is there any way I can add a command to the bash script to login as root without having to type su then the password?

Cheers,

Answer 1

在iOS中不允许SUDO和系统功能，因为它们违反了沙箱和安全性。

Answer 2

That's the solution worked for me:

1. Jaibreak
2. Install sudo from Cydia
3. Install OpenSSH from Cydia

4. SSH to your iPhone

    $ssh root@<your iphone ip> Password: alpine //no echo 

   and run

    iPhone:~ root# visudo 

   add right after

    root ALL=(ALL) ALL 

   this line (varies of what you want)

    mobile ALL=(ALL) ALL 

5. Save changes. Now you can sudo . For editing with visudo you should use controls like in vi

6. After all add to your script hardcoded sudo call like this

    #!/bin/bash sudo -S -p "" echo -n "" <<! alpine ! sudo echo "This line is printed as root" 

   Now explanation:

   • -S allows reading password from <<!\\n ... \\n! block, it should be printed on a single line
   • -p "" suppresses password promt, so the line Password: is not printed
   • echo -n disallows a newline character in the end

So you can sudo in your script without any password promt. The only thing - in this method password is hardcoded. But you can try command line arguments like $1 (not tested, just an idea)
