Introduction to SSHD on Mac
Before delving into the methods of restarting SSHD on your Mac, let’s understand what SSHD is and its significance in secure remote access. SSHD is an SSH server daemon that listens for incoming SSH connections and handles the authentication process. It ensures secure and encrypted communication, preventing unauthorized access to your system. Restarting SSHD can help resolve connectivity issues, apply configuration changes, and ensure smooth functioning of SSH on your Mac.
In the following sections, we will explore multiple techniques to restart SSHD seamlessly.
Methods to Restart SSHD
In this section, we will discuss three primary methods to restart SSHD on your Mac:
- Restarting SSHD via Terminal
- Using Launchctl to Restart SSHD
- Restarting SSHD via System Preferences
Restarting SSHD via Terminal
The Terminal is a powerful command-line tool available on macOS, allowing you to interact with your system swiftly. To restart SSHD using Terminal, follow these steps:
- Open Terminal by navigating to Applications > Utilities > Terminal.
- Type the following command and press Enter to stop the SSHD process:
sudo launchctl stop com.openssh.sshd. - Enter your Mac’s password when prompted, as the command requires administrative privileges.
- Next, restart SSHD by executing the command:
sudo launchctl start com.openssh.sshd. - You have successfully restarted SSHD via Terminal. Test the connectivity to ensure SSH is functioning correctly.
Checking SSHD Activity Status
To verify the status of SSHD before and after restarting, use the following command in Terminal:
sudo launchctl list | grep sshd
This command displays the status and availability of SSHD on your Mac.
Using Launchctl to Restart SSHD
Launchctl is a command-line interface for managing macOS launchd services, including SSHD. Follow the steps below to restart SSHD using Launchctl:
- Launch Terminal from Applications > Utilities > Terminal.
- Enter the following command and press Enter:
sudo launchctl unload /System/Library/LaunchDaemons/ssh.plist(to stop SSHD). - Provide your Mac’s password when prompted.
- Next, restart SSHD by executing:
sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist(to start SSHD). - SSH is now restarted using Launchctl. Test its functionality for reassurance.
Restarting SSHD via System Preferences
An alternative method to restart SSHD is through the System Preferences window. Follow these steps:
- Click on the Apple menu in the upper-left corner of your screen and select System Preferences.
- Within the System Preferences window, click on Sharing.
- On the left-hand side, locate and check the Remote Login option.
- To apply the changes, uncheck and recheck the Remote Login option.
- SSH is now restarted via System Preferences. Test its connectivity for verification.
Configuring SSHD Autostart
If you want SSHD to start automatically upon system boot, follow these steps:
- Open Terminal from Applications > Utilities > Terminal.
- Type the following command and press Enter to enable SSHD autostart:
sudo launchctl enable system/com.openssh.sshd. - Enter your Mac’s password when prompted.
- SDH will now automatically start upon system reboot.
