Connecting to a server via SSH from Linux¶

To connect to your server via SSH from Linux, follow these steps:

Check for the server's IP address. Make sure you know the server's IP address. If you don't know it, you can find it in the Invapi Control Panel.
Install an SSH client (if necessary). An SSH client is usually already installed by default on most Linux distributions. To check this, open a terminal and run the command:
```
ssh --version
```
If the client is installed, you will see the program version.

If the SSH client is not installed, install it using your distribution's package manager:
- For Ubuntu/Debian:
```
sudo apt update
sudo apt install openssh-client
```
- For CentOS/RHEL:
```
sudo yum install openssh-clients
```
Connect to the server. Open a terminal and enter the following command:
```
ssh <username>@<server IP address>
```
For example:
```
ssh [email protected]
```
Enter your password. After connecting, the system will prompt you to enter the password for the specified user. The server's login and password are sent to you via email when it is delivered.

Check for the server's IP address. Make sure you know the server's IP address. If you don't, you can find it in the Invapi Control Panel on the HOSTKEY.com website at https://invapi.hostkey.com.
In Windows 11, there are several ways to connect to a server via SSH:

Starting with the October 2018 Update of Windows 10, the SSH client is included by default. To check this, run PowerShell and execute:
```
ssh
```
If the client is installed, you will see output options for its use.

If the SSH client is not installed, enable it through Settings:

1. Go to **Settings** > **System** > **Additional components**.

2. Find `OpenSSH Client` and install it.

Connect to the server. Open PowerShell and enter the following command:
```
ssh <username>@<server IP address>
```
For example:
```
ssh root@192.168.0.100
```
Enter your password. After connecting, the system will prompt you to enter the password for the specified user. The server's login and password are sent to you via email when it is delivered.

Download PuTTY from the official website https://www.putty.org.
Launch PuTTY and enter the server's IP address in the field "Host Name (or IP address)".
Specify the connection type as SSH and click Open.
Connect to the server:
- Enter the server's IP address in the field Host Name (or IP address).
- Specify port 22 for SSH if it has been changed.
- Click Open. In the window that opens, enter your username and password.
Enter your password. After connecting, the system will prompt you to enter the password for the specified user. The server's login and password are sent to you via email when it is delivered.

Note

It is recommended to use SSH keys instead of passwords for more secure authentication. Instructions for setting up SSH keys can be found in your distribution's documentation or in our guide.
If you receive an error Connection refused, make sure that the SSH server is running on the target server and port 22 is open in the firewall.
