Detailed Ubuntu under the installation and Landing SSH service (SSH remote login) _linux

Ubuntu does not have SSH service installed by default, and if you connect to Ubuntu remotely via SSH, you will need to manually install Ssh-server.

To determine whether or not to install the SSH service, you can do so by using the following command:

Ps-e|grep SSH

The output is as follows:

zht@zht-ubuntu:~$ ps-e|grep ssh
 2151?    00:00:00 ssh-agent
 5313?    00:00:00 sshd

Ssh-agent said Ssh-client started, Sshd said Ssh-server started.

If sshd is missing, the SSH service is not started or is not installed.

To install the ssh-client command:

sudo apt-get install openssh-client

To install the Ssh-server command:

sudo apt-get install Openssh-server

After the installation is complete, start the service first:

Sudo/etc/init.d/ssh start

After startup, you can view the correct startup through Ps-e|grep ssh.

SSH Service The default port is 22, you can change the port, and use the following command to open the SSH configuration file:

sudo gedit/etc/ssh/sshd_config

The contents of the configuration file are as follows:

# Package generated configuration file   
# the SSHD (8) manpage   
for details # What ports, IPs and protocols we Sten for  
Port 
# Package generated configuration file # and the 
sshd (8) manpage for details 
# What Ports , IPs and protocols we listen for 

After modifying the port number (port), restarting the SSH service will take effect with the following commands:

Sudo/etc/init.d/ssh restart

SSH service is launched, you can login, login command format: SSH account @ip Address

For example:

SSH test@192.168.135.249

When prompted to enter the password for test, you can log on remotely.

Exit Remote login Command: Exit
