Those who want some kind of graphical user interface SSH client on Linux to connect and manage remote servers can go for the popular PuTTY SSH GUI client on Debian 11 or 10. For SSH GUI client on Debian 11- Use PuTTY In this way, we can connect any Debian 11 Bullseye remotely using SSH running locally or remotely on Cloud or some hosting service. In short the password of the user you have mentioned in the SSH command. The authenticity of host '192.168.1.44 (192.168.1.44)' can't be established.ĮCDSA key fingerprint is SHA256:6QRijBGfGDd1UiYOBeCEQ7Hx4oW453mEn8OO/Xm6RLk.Īre you sure you want to continue connecting (yes/no/)?Īfter that enter the password for the user you want to connect on the remote system using ssh. Once the connection is established the system will ask you to accept the ECDSA key fingerprint. In the above command replace the user with the one you have on your remote Debian 11 or any other system that you want to connect over SSH and server-ip-address with the address of where you have OpenSSH-server installed.įor example– our Debian 11 IP address is 192.168.1.44 and user – h2s and to connect from Windows or Linux using terminal the command will be in this way. Debian/Ubuntu users can go for- sudo apt install openssh-client where RHEL based Linux (CentOS, Rocky, Alma, Fedora)- sudo dnf install openssh-client If you are using Windows then ssh is already there whereas Linux users may need to install an SSH client. Note down the IP address and move to the local system or the one from where you want to access the remote Debian 11 system. Install and Configure UFW Firewall on Debian 11 Bullseye or 10 Busterįirst, find out the remote Debian 11 server or desktop IP address where you have installed the OpenSSH. Those interested in having a UFW firewall can refer to this article: If you have an active firewall on Debian 11 then also whitelist the port in it to let the system accept the public connections over port number 22. Whereas to stop and restart the service, commands are: sudo systemctl start sshd However, if it is not actively running on your system, then run: sudo systemctl enable -now sshd There has been a massive increase in the number of scans on port 22, that is typically used by the SSH server. We can confirm the same using: systemctl status sshd Once the installation is completed, the system will automatically start and enable the service of the SSh server. The packages to install it are already in the system’s default repo, hence, nothing to do except running of the given command. Next, use the APT package manager and install the OpenSSH server on Debian 11 that you want to access remotely using this protocol. Well, first refresh the APT cache so that the system could recognize any recent updates available to download and install or cache. For SSH GUI client on Debian 11- Use PuTTY Steps to install and enable SSH on Debian 11 Bullseye server 1. Please consider things such as the physical location of the machine, etc, before completely disabling sshd. It seems you've deviated from default and without more details it's hard to know exactly what's going on.ĭepending on the requirements, removing the package providing sshd ( openssh-server) would be a more fool-proof approach. $ sudo systemctl stop rvice sshd.socketĪs it has been mentioned, Ubuntu's openssh-server only installs ssh.service, and no socket. One is dependent on the other and will not be disabled unless done in the proper order. This is the portable version of OpenSSH, a free implementation of the Secure Shell protocol as specified by the IETF secsh working group. You need to stop and disable both of these using systemctl, likely the socket first, and then the service. You can see that with your systemctl command, you have rvice and sshd.socket. No new connections should be able to become established. If I'm not mistaken, any existing ssh connections will be maintained even after running systemctl stop sshd. You can use systemctl disable sshd so that sshd will not be started when you turn the system on in the future. You can stop a service with systemctl, but you need to also disable it and anything that would cause it to start up.
