The best known example application is for remote login to computer systems by users. Sometime you need to have basic tools to SSH to the server.

For Linux/Mac User

The process on Linux and Mac OS are generally the same. Below we use Ubuntu as an example.

ssh root@192.168.8.1

If you have ever connected to another router, host key verification failed may displayed as follow:

If this happens, run the command in the red box. Please copy the exact command which is displayed in your terminal.

ssh-keygen -f "~/.ssh/known_hosts" -R "192.168.8.1"

You may also encounter the following error when connecting:

Unable to negotiate with 10.0.0.1 port 22: no matching host key type found. Their offer: ssh-rsa

This error is due to a change in the Openssh package from version 8.8. To fix it, open the ~/.ssh/config file with a text editor (you can use for example Nano or Vim) and add the following lines:

host 192.168.8.1
    HostkeyAlgorithms +ssh-rsa
    PubkeyAcceptedAlgorithms +ssh-rsa

Make sure to change the host IP if it is not the default one.

2. Log In Router

Retry the SSH login command:

ssh root@192.168.8.1

Type "yes"

Input your router password: (you can set this password when you first connect to your router)

Finally, you login the router when the above message displayed.
