Replicant

h1. SSH

This tutorial was tested on Replicant 6.0, it might or might not work on older Replicant versions.

This tutorial assumes that you already know how to use OpenSSH and that you already generated some SSH keys on your computer.

First, connect your smartphone or tablet to your computer trough USB, and make sure that ADB is already setup. If it is not, you can follow the [[ADB|explanations on how to setup ADB]].

Then on your computer, make sure to give adb root permissions:

<pre>

$ adb root

</pre>

OpenSSH requires some host keys to work, generate them on your smartphone/tablet with:

<pre>

$ adb shell "/system/bin/ssh-keygen -A"

</pre>

OpenSSH also needs a configuration file in /data/ssh/sshd_config, and by default the /data/ssh/sshd_config doesn't exist. Since we have an example configuration file in /etc/ssh/sshd_config, we can use it.

First copy the smartphone/tablet's /etc/ssh/sshd_config to your computer.

<pre>

$ adb pull /etc/ssh/sshd_config

</pre>

Then edit the file if you wish to change configuration options.

<pre>

$ adb push sshd_config /data/ssh/sshd_config

</pre>

Then, to permit accessing the smartphone/tablet with your SSH key, you need to copy your public key to the smartphone/tablet. This can be done with:

<pre>

$ adb push ~/.ssh/id_rsa.pub /data/ssh/authorized_keys

</pre>

Then you can start OpenSSH with:

<pre>

$ adb root

$ adb shell "/system/bin/sshd"

</pre>

Note that OpenSSH won't be started automatically at boot, so after rebooting the smartphone/tablet, it will need to be started again manually.

You should then be able to ssh into the smartphone/tablet with:

<pre>

$ ssh root@192.168.43.1

</pre>
