Straight to the point, in this tutorial we'll learn how to install SSH on Ubuntu to securely access it from a local computer. You can basically break down SSH in two. You can enable SSH service during installation of openSUSE and SLES at the Firewall and SSH section on the Installation Settings screen. This quick tip shows Ubuntu beginners how to enable the secure shell (SSH) service in Ubuntu 19.10. SSH, also known as Secure Shell or Secure Socket Shell, is a network protocol or operating. Enable Kali Linux Remote SSH Service First, you must remove the run levels by entering the following command. $ sudo update-rc.d -f ssh remove The next step is to load SSH defaults. In Windows, sshd reads configuration data from%programdata%sshsshdconfig by default, or a different configuration file may be specified by launching sshd.exe with the -f parameter. If the file is absent, sshd generates one with the default configuration when the service is started.
SSH Service enable or disable Huawei OLT
Today i will show how to SSH Service enable or disable in Huawei OLT. When you need to disable or enable the network service ports such as the DBWIN, ntp, radius, snmp, SSH, Telnet and Trace in the system, run below command. After the command is executed successfully, the monitoring task of the corresponding port is disabled or enabled.
Format:
sysmanservice{ dbwin | dhcp-relay | dhcpv6-relay | ntp6 | ntp | radius | snmp | ssh-tl1 | ssh | telent-proxy | telnet-tl1 | telnet [ portportid ] | trace }{ disable | enable }
Parameters:
| Parameter | Description |
|---|---|
| dbwin | Indicates the DBWIN service. |
| dhcp-relay | Indicates the DHCP relay service. |
| dhcpv6-relay | Indicates the DHCPv6 relay service. |
| ntp6 | Indicates the Ntp IPv6 net service. |
| ntp | Indicates the NTP service. |
| radius | Indicates the radius service. |
| snmp | Indicates the SNMP service. |
| ssh-tl1 | Indicates the SSHservice of TL1. |
| ssh | Indicates the SSHservice. |
| telnet-proxy | Indicates the telnet proxy service. |
| telnet-tl1 | Indicates the telnet service of TL1. |
| telnet | Indicates the telnet service. |
| portportid | Indicates the portid used by telnet service. |
| trace | Indicates the trace service. |
| enable | Enables the network service ports. When you need to enable the network service ports, use this parameter. |
| disable | Disables the network service ports. When you need to disable the network service ports, use this parameter. |
Modes:
Level:
Usage Guidelines:
- After a network service port is disabled, the user on the port is forced to go offline.
- By default, only the DBWIN, TRACE, SSH-TL1, and TELNET-TL1 network service are disabled.
To query the status of the network service port of the system, do as follows:
SSH Service enable or disable Example:
To disable a SSH service port, do as follows:
Gponsolution(config)#sysman service
{ dbwin<K>|dhcp-relay<K>|dhcpv6-relay<K>|ntp6<K>|ntp<K>|radius<K>
|snmp<K>|ssh-tl1<K>|ssh<K>|telnet-proxy<K>|telnet-tl1<K>|telnet<K>|trace<K> }:ssh
{ disable<K>|enable<K>|port<K> }:disable
Command:
sysman service ssh disable
After the command is executed successfully,all the network service of the same
type will be forcibly disabled. If you want to enable the network service
again,wait for at least two minutes and then enable it. Are you sure to
continue? (y/n)[n]:y

In this tutorial we are going to learn how to install and configure SSH Server on Ubuntu Server/Desktop Operating System. The Secure Shell (SSH) is the most common and secure way to manage Ubuntu using a command line from a remote location.
For this tutorial I am using Ubuntu 18.04 LTS, But you can use the following guide to setup SSH Server on any previous Ubuntu version.
Install OpenSSH Server on Ubuntu 18.04
The SSH Server for Ubuntu is provided by the openssh-server package. If not already installed, you can install openssh-server package in Ubuntu 18.04, using the apt-get install command.
To install OpenSSH, open the Ubuntu terminal and execute:
This will install the SSH Server on our Ubuntu System.
Start SSH Server on Ubuntu
OpenSSH Server should start automatically after the installation, if not, to start the SSH Server on Ubuntu 18.04, we use the systemctl command.
In Ubuntu 14.04 use service command to start the ssh service.
Enable SSH root login in Ubuntu
By default SSH Server in Ubuntu do not allow to connect to the server using the root username. In order to allow root SSH Login we need to change PermitRootLogin to yes in the /etc/ssh/sshd_config file.
First, Open the /etc/ssh/sshd_config file.
Then locate the line PermitRootLogin directive, uncomment (remove the # in front) and change its value to yes.
Then, Save the SSH Configuration file and restart the SSH Server.
Or
Now you can login to the Ubuntu SSH Server using the root user Account.
Enable Ssh Service Linux
Summary - Setup SSH Server on Ubuntu
In this tutorial we learned how to install SSH Server on Ubuntu Linux.
Enable Ssh Service On Kali
- SSH Server for Ubuntu provides by the openssh-server package. OpenSSH is the most widely deployed SSH server in the world
- By default Root Login to the SSH Server is disabled in Ubuntu Linux.
- To enable Ubuntu root SSH login, we need to set PermitRootLogin yes in the /etc/ssh/sshd_config file.
