How to Fix: systemd service error: no route to host after booting

                The primary reason for this error is that the `systemd` service does not wait for the network configuration to be fully completed before running the specified service. This can lead to an incomplete routing table, causing the 'no route to host' error.An alternative reason could be a misconfigured network interface or a faulty Ethernet cable, which may prevent the remote machine from being reachable via IP address.

            🚀 How to Resolve This Issue

                Modifying the systemd service to wait for network configuration

                    Step 1: Edit the `/etc/systemd/system/feedback.service` file and add the `After=network.target` directive to ensure that the service runs after the network is fully configured. This can be done by adding the following line under `[Unit]`: `After=network.target`Step 2: Restart the `systemd` service manager using the command `systemctl daemon-reload` to apply the changes.Step 3: Verify that the service is running correctly by checking its status with `systemctl status feedback`.



                Adding a sleep period to wait for network configuration

                    Step 1: Modify the `/usr/local/bin/feedback.sh` file to include a sleep period before attempting to establish the Telnet connection. This can be done by adding the following line at the top of the script: `sleep 10`Step 2: Restart the service with the modified script using the command `systemctl restart feedback`.


            💡 Conclusion
            To resolve the 'systemd service error: no route to host' issue, you can either modify the systemd service to wait for network configuration or add a sleep period to allow for proper routing table setup. By following these steps, you should be able to establish a successful Telnet connection to your remote machine.
