Editing Cursor SSH:Setup (section)

== Step-by-Step Configuration ==

=== 1. Enable SSH and Root Access on Raspberry Pi ===

'''Enable SSH server (on Raspberry Pi):'''
<pre class="lang-bash">
sudo systemctl enable ssh
sudo systemctl start ssh
</pre>

'''Or via raspi-config:'''
<pre class="lang-bash">
sudo raspi-config
== Navigate to: Interfacing Options → SSH → Enable ==
</pre>

'''Enable root SSH access (on Raspberry Pi):'''
<pre class="lang-bash">
== Set root password (if not already set) ==
r

== Enable root login via SSH ==
sudo sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
== Or if using password auth: ==
sudo sed -i 's/#PermitRootLogin yes/PermitRootLogin yes/' /etc/ssh/sshd_config

== Restart SSH service ==
sudo systemctl restart ssh
</pre>

'''Verify SSH is running:'''
<pre class="lang-bash">
sudo systemctl status ssh
== Should show: active (running) ==
</pre>

'''Test root SSH access:'''
<pre class="lang-bash">
ssh root@localhost
== Should connect as root ==
</pre>

=== 2. Configure SSH on Your Local Machine ===

Create or edit <code>~/.ssh/config</code> on your local machine (where Cursor is installed):

<pre class="lang-bash">
==== On your local machine (not the VPS) ====
nano ~/.ssh/config
</pre>

Add the following configuration:

<pre>
Host raspberrypi
    HostName 87.106.61.62
    Port 22223
    User root
    IdentityFile ~/.ssh/id_rsa
    ServerAliveInterval 60
    ServerAliveCountMax 3
    StrictHostKeyChecking no
    UserKnownHostsFile ~/.ssh/known_hosts
</pre>

'''Configuration Options:'''
* <code>Host raspberrypi</code>: Alias name (use any name you prefer)

* <code>HostName 87.106.61.62</code>: Your VPS public IP

* <code>Port 22223</code>: External port for Raspberry Pi forward

* <code>User root</code>: Username on Raspberry Pi (using root for Cursor)

* <code>IdentityFile ~/.ssh/id_rsa</code>: Path to your SSH private key

* <code>ServerAliveInterval 60</code>: Keep connection alive (prevents timeouts)

=== 3. Set Up SSH Key Authentication (Recommended) ===

'''On your local machine:'''

==== '''Generate SSH key pair''' (if you don't have one): ====
   <pre class="lang-bash">
   ssh-keygen -t ed25519 -C "cursor-raspberrypi"
=== Or use RSA: ssh-keygen -t rsa -b 4096 ===
</pre>
