Within the System ➤ Administration page, you can configure the Router Password, SSH, Telnet, Web, and FTP settings.
Password: Allows you to set the router password, the default being password.
Confirmation: Requires you to re-enter the password.
SSH: Allows you to access the router's Linux shell and file system using the Secure Shell protocol. For example, the programs PuTTY and WinSCP can be used.
Interface: Lets the device listen on a given interface or all interfaces.
Port: Specifies the listening port, the default being 22.
Password authentication: Allows SSH password authentication.
Allow root logins with password: This is enabled by default.
Gateway ports: Allow remote hosts to connect to local SSH forwarded ports.
Telnet: Provides administrator tools for controlling the device or network debugging, over an unencrypted connection.
Port: Specifies the listening port, the default being 23.
To start using Telnet, enter the command
“telnet 192.168.1.1 23”
into a Command Prompt if using Windows, or into a Terminal if using Linux or Mac OS X. This is assuming that 192.168.1.1 is the IP address of your router.
The splash page of OpenWRT appears after login. Commands can then be entered into the Linux shell of the router, e.g. ifconfig, iwconfig, iwpriv, uci show, ls /bin, ls /sbin, ls /usr/bin, or ls /usr/sbin.
Web Server Mode: This can be set to Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol Secure (HTTPS). For HTTPS, if you see the warning, “The certificate is not trusted because it is self-signed.
The certificate is only valid for OpenWRT,” click “Add Exception”, “Confirm Security Exception” and proceed. Port: Specifies the listening port, the default being 80 for HTTP and 443 for HTTPS.
