SSH Log in to the Router¶

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. Sometime you need to have basic tools to SSH to the server. This guide is about how to SSH login to the GL.iNet routers.

For Windows User¶

There are many tools, like Windows PowerShell, PuTTY, Bitvise.

Using Bitvise¶

Using PuTTY¶

1. Download PuTTY¶

Download the latest PuTTY version from here.

2. Install PuTTY¶

Putty Install 1

Putty Install 2

Putty Install 3

Putty Install 4

3. Launch PuTTY¶

Click PuTTY from the Start Menu.

Launch Putty

You will see the following Configuration Window.

Setup Putty 1

Input Host Name (or IP address) 192.168.8.1, keep Port as default 22, select connection type as SSH.

Input Your Session in saved sessions, and Save your content.

For Linux/Mac User¶

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

Using Ubuntu¶

1. Launch Terminal¶

Run Ubuntu.

Run Ubuntu

Click the Terminal icon to launch Terminal. Then input the following command:

ssh root@192.168.8.1

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

remove_ssh_keygen

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"

removed_host_keygen

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

Ubuntu sshin router 1

Type "yes".

Ubuntu sshin router 2

Then input your router password. You can set this password when you first connect to your router.

Ubuntu sshin router 3

When you see a picture above, it means you login the router successfully.

Troubleshooting¶

No matching host key type found. Their offer: ssh-rsa
