How do I set up GDB for remote debugging over SSH?

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, connect to the remote GDB server using: gdb <program> and then use the command target remote <remote_ip>:<port>. Would you like more details on any specific step?

What if I want to use a different port?

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 that the port is open and not blocked by any firewall.

Can I use SSH tunneling for added security?

Yes, you can use SSH tunneling for added security. You can create a tunnel with the command: ssh -L <local_port>:localhost:<remote_port> user@remote_ip. Then, connect GDB to localhost:<local_port> instead of the remote IP.

What if I encounter connection issues?

If you encounter connection issues, check the following: 1. Ensure the GDB server is running on the remote machine. 2. Verify that the correct IP and port are being used. 3. Check firewall settings on both machines to ensure the port is open.
