2. Run the command ‘service sshd restart’ to restart SSH service

Command 1 : service sshd restart

OR

command 2 : /etc/init.d/sshd restart

You can either use the command “service sshd restart” OR “/etc/init.d/sshd restart” to restart SSH service. There is no need to run both commands.

[root@server ~]# service sshd restart
Stopping sshd: [ OK ]
Starting sshd: [ OK ]

[root@server ~]# /etc/init.d/sshd restart
Stopping sshd: [ OK ]
Starting sshd: [ OK ]



HOW TO STOP SSH SERVICE ON CENTOS/REDHAT 6 SERVERS

Do the below steps to stop SSH service on linux server.

IMPORTANT : You might get disconnected from the server if you stop SSH service on your server. You can safely stop SSH service only if you have console access to the server.

Command to stop SSH service on centOS/RHEL linux server is given below.

1. Log into your linux server via SSH as ‘root’ user

2. Run the command ‘service sshd stop’ to stop SSH

Command 1 : /etc/init.d/sshd stop

OR

Command 2 : service sshd stop

root@server [~]# /etc/init.d/sshd stop
Stopping sshd: [ OK ]

OR

How To Restart Server Service

OR

Command 2 : service sshd start

Start Openssh Server

root@server [~]# /etc/init.d/sshd start
Starting sshd: [ OK ]

OR

root@server [~]# service sshd start
Starting sshd: [ OK ]

[OK] = This means service is started successfully
[Failed] = Means the service failed to start for some reason. Example : The service won’t start if the disk space is 100% full or if there is high load on the server. You must check the server logs to find the exact error and troubleshoot accordingly.

HOW TO CHECK THE STATUS OF SSH SERVICE

Run the command ‘service sshd status’ to check the current status of SSH service. This command will show whether SSH service is running or stopped on your linux Server.

The below shows that SSH service is running fine on the server.

Command : service sshd status

OR

Command : /etc/init.d/sshd status

root@server [~]# service sshd status
openssh-daemon (pid 14945) is running…

root@server [~]# /etc/init.d/sshd status
openssh-daemon (pid 14945) is running…

‘14945’ is the process ID of the SSH process. Killing this process ID will stop SSH service and you will get disconnected from the server.

If the SSH service is down on the server it will show “openssh-daemon is stopped”

root@server [~]# service sshd status
openssh-daemon is stopped


“openssh-daemon is stopped” is stopped means the service is not running on your server. You can run the command “service sshd start” to start the service. You must check the server logs if you are unable to start the service.

In this article, I will show you how to enable the OpenSSH server on Windows 10 and how to connect through ssh to a Windows 10 machine.

By default, recent versions of Windows 10 have an OpenSSH client already installed, this means that you can use a Windows 10 machine to connect through ssh to other machines, typically Linux servers, that have an ssh server enabled. How about when you want to be able to connect through ssh to another Windows computer ?

Go to the Windows Start menu and select Settings, next go to AppsOptional featuresAdd a feature, on this page, search for OpenSSH Server or scroll until you find it and check the left box. Press Install.

Once the installation has finished, you need to start the OpenSSH server in order to be able to connect to this machine. Open a PowerShell window as an Administrator: go to StartWindows Power Shell and right click on the Windows Power Shell app select More and pick Run as administrator, answer Yes when asked if you want to let this app to make changes to your device.

At this point, you can temporarily enable the OpenSSH server by writing the next command in Windows Power Shell:

You can connect to your Windows machine with:

If you need to find your IP address, run this command in PowerShell:

Windows Openssh

When you will stop or restart Windows, the OpenSSH server will be also stopped. If you need to reenable it, you can use the above command to start the service or, if you know that you want this to be on permanently, write the next two commands in a PowerShell administrator window:

The above will ensure that after a restart the sshd service will be always on. Mathmr. macs class 2019 20.
