-^ Copy a local file to iOS:

scp /path/to/localFile user@iOSIP:/path/to/remoteFile

For instance:

snakeninnysiMac:~ snakeninny$ scp ~/1.png [email protected]:/var/tmp/

-^ Copy a file from iOS to the local system:

scp user@iOSIP:/path/to/remoteFile /path/to/localFile

For instance:

snakeninnysiMac:~ snakeninny$ scp [email protected]:/var/log/syslog ~/iOSlog

These two commands are relatively simple and intuitive. After installing OpenSSH, make

sure to change the default login password “alpine”. There’re 2 users on iOS, i.e. root and

mobile, we need to change both passwords like this:

FunMaker-5:~ root# passwd root

Changing password for root.

New password:

Retype new password:

FunMaker-5:~ root# passwd mobile

Changing password for mobile.

New password:

Retype new password:

If we forget to change the default password, there’re chances that viruses like Ikee login as

root via ssh. This leads to very serious security disasters: all data on iOS including SMS, contacts,

AppleID passwords and so on is at the risk of leaking, the intruder can take control over your

device and do whatever he wants. Therefore, promise me you’ll change the default password

after installing OpenSSH, OK?

4.6 usbmuxd

Most of you ssh into iOS via WiFi, which leads to slow responses in remote debugging or

file copying. This is because of the instability of wireless network and the limitation of

transmission speed. The well-known hacker, Nikias Bassen (@pimskeks) has written a tool

named usbmuxd to forward local OSX/Windows port to remote iOS port. With this tool, we

can ssh into iOS via USB, greatly increasing the speed of SSH connection. usbmuxd is easy to

use:

1. Download and configure usbmuxd
