In this article, we will explore a recent issue encountered with a new Fedora 39 machine that fails to register an SSH connection after resuming from suspension. We will discuss the possible causes, provide troubleshooting steps, and suggest potential solutions to resolve the problem.

Background

Suspending a machine is a common power management technique that allows users to save energy while keeping their work intact. However, resuming from suspension may sometimes cause issues, especially when it comes to network connectivity and SSH registration.

Possible Causes

The following are some possible causes for the Fedora 39 machine failing to register an SSH connection after resuming from suspension:

• Network interface driver issues
• Power management settings
• SSH daemon misconfiguration
• Firewall rules blocking SSH connections

Troubleshooting Steps

To troubleshoot this issue, follow these steps:

1. Check the network interface status:

   ip a

2. Ensure that the network interface is up and has an IP address.
3. Check the SSH daemon status:

   systemctl status sshd

4. Verify that the SSH daemon is running and enabled.
5. Check the firewall rules:

   firewall-cmd --list-all

6. Ensure that the firewall allows incoming SSH connections.
7. Check the power management settings:

   cat /sys/class/scsi_host/host*/power/control

8. Ensure that the power management settings are set to "auto" or "on".
9. Check the system logs for any related error messages:

   journalctl -b -1

Potential Solutions

Based on the troubleshooting steps, some potential solutions to resolve the issue include:

• Updating the network interface driver
• Modifying the power management settings
• Reconfiguring the SSH daemon
• Adjusting the firewall rules
