Some server providers, such as Amazon EC2 and Google Compute Engine, disable SSH password authentication by default. That is, you can only log in over SSH using public key authentication.
SFTP is a protocol that runs over SSH, so this means SFTP using passwords will not work by default when SSH password authentication is disabled.
ASA(config)# username ithelp21 password adminwin.ru privilege 15. Asa(config)# ssh version 2. For some oneAPI applications, you must configure a password-less SSH connection for the root user on the target system; for example: IoT applications that use the MRAA/UPM sensor library Any application that interacts with system resources that require su, sudo, or root access Any tool that requires remote root or sudo access to your target. Set up SSH # There are several authentication methods into a VM, including an SSH public/private key pair or a username and password. We strongly recommend using key-based authentication (if you use a username/password, you'll be prompted to enter your credentials more than once by the extension). Regarding the configuration file, you may use a different configuration file or use.ssh/config and write your own code to parse that file and get the password for a given user and host.
To enable SSH password authentication, you must SSH in as root to edit this file:
Then, change the line
to
Using tor on kali. After making that change, restart the SSH service by running the following command as root:
Enable Logging In as root
Some providers also disable the ability to SSH in directly as root. In those cases, they created a different user for you that has sudo privileges (often named ubuntu). With that user, you can get a root shell by running the command:
If you instead want to be able to directly SSH in as root, again edit this file:
And change the line
to
After making that change, restart the SSH service by running the following command as root:
If you enable this setting, don't forget to set a strong password for root by running the command.
Short and complete guide to configure SSH on Cisco router and switch for secure remote connection. The Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. The best-known example application is for remote login to computer systems by users.
SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server. Common applications include remote command-line login and remote command execution, but any network service can be secured with SSH. The protocol specification distinguishes between two major versions, referred to as SSH-1 and SSH-2.
The typical use of SSH Protocol
The protocol is used in corporate networks for:
- providing secure access for users and automated processes
- interactive and automated file transfers
- issuing remote commands
- managing network infrastructure and other mission-critical system components.

Configure SSH on Cisco Router or Switch
To configure SSH on Cisco router, you need to do:
- Enable SSH on Cisco router.
- Set Password for SSH.
- Force remote access to use SSH.
- Enable Password Encryption.
- Add domain name Server (DNS).
- Add Username and Password.
Ssh Config File Example
Let’s enable and configure SSH on Cisco router or switch using the below packet tracer lab. The configure on a packet tracer lab and real Cisco devices are the same. Sethbling. Just try to learn and do it what the SSH remote authentication needs.
Download the packet tracer lab or create your own lab. SSH Configuration Packet Tracer Lab.
In this example, I just enable and configure SSH on SW1 and trying to access it from PC1. It’s enough to learn how to configure SSH on Cisco router.
That’s all. Let’s check the process one by one.
- I have set DNS domain name with “IP domain-name” command.
- Then configure the router to use RSA key pair with modulus size of 1024 bites for remote service authentication with “crypto key generate rsa” command.
- Add username “Admin” with Password of “Technig” for ssh authentication.
- Enabled ssh with “line vty 0 4” command.
- Configure ssh to use local username and password with “login local” command. Remember that you can set a username and password for ssh with “username Admin password Technig” command as well. But here we configure ssh to use local username and password.
- Configure the router to accept only ssh connection with “transport input ssh” command.
- Configure ssh to version 2 using “IP ssh version 2” and set the authentication times to 3 with “IP ssh authentication-retries 3” command.
- Finally set the ssh timeout to 120 seconds with “IP ssh time-out 120” command.

The final step is to test the connectivity of ssh from PC1 with “ssh -l Admin 192.168.1.1” command for command prompt.

OK, the ssh works perfectly.
