Installing a SSH server on Ubuntu
On May 04,2023 by Tom Routley
SSH server allows users to connect remotely in a secure way and allows access to file transfers. Installation of the SSH server on Ubuntu requires the use of command 'sudo aptitude install ssh' and through the Login ID and the password reported in Ubuntu , one can have encrypted remote access. To connect, the command line must be used and the server can be accessed from Windows through open source clients such as PuTTY and WinSCP. SSH server can be installed through a proxy server after the package connect-proxy gets installed.
An SSH server allows you to remotely access your machine.
You'll have access to the remote console (equivalent to telnet, but secure) and the ability to transfer files.
Installation
The easiest way is to use: sudo aptitude install SSH
You can now connect remotely in a secure way.
Use the login/password of users reported in Ubuntu.
Connection
You can use ssh command line: ssh mylogin@ipaddress
You can also access it from Windows:
with Putty for the command line: http://ccmet/download/download 918 putty
with WinSCP to transfer files: http://ccmet/download/download 3382 winscp
SSH through a proxy
First install the package connect-proxy:
sudo aptitude install connect-proxy
Edit /etc/ssh/ssh_config to enable SSH via proxy:
to enable SSH via proxy: sudo echo 'ProxyCommand /usr/bin/connect-proxy -4 -S monproxy.domaineom:port %h %p' >> /etc/ssh/ssh_config
Be sure to replace "proxy.domaineom" and "port" with the name of your proxy and port number.
Additional tip
To run the ssh server on another port which the port 22 standard:
1. Open the configuration file: sudo gedit/etc/ssh/sshd_config
2. Locate the line Port 22 and replace by the value of your choice (eg port 741 )
and replace by the value of your choice (eg ) 3. Restart the ssh server: sudo/etc/init.d/ssh restart
This little trick ensures that the server is identified by a scan of IP address ranges, and thus reduce some risks.
