How can I set up GDB for remote debugging over SSH tunneling?

To set up GDB for remote debugging over SSH, you need to follow these steps: 1. Ensure GDB is installed on both local and remote machines. 2. On the remote machine, start GDB server with the command: gdbserver :<port> <program>. 3. On your local machine, use SSH to create a tunnel: ssh -L <local_port>:localhost:<remote_port> user@remote_host. 4. Finally, connect GDB to the server using: target remote localhost:<local_port>.

What if I want to use a different port for GDB server?

You can specify any available port when starting the GDB server. Just replace <port> in the command gdbserver :<port> <program> with your desired port number. Make sure to update the SSH tunnel command accordingly.

Can I use this method for debugging applications on embedded systems?

Yes, you can use GDB remote debugging over SSH tunneling for embedded systems as long as you have GDB and the necessary tools installed on both the host and the target device. Just ensure that the embedded system is accessible over SSH.

Are there any security concerns I should be aware of?

Yes, when using SSH tunneling, ensure that your SSH keys are secure and consider using strong passwords. Additionally, limit SSH access to trusted IP addresses to enhance security.
