CLI can be reached through the router's WebUI. To reach the router's WebUI, simply enter the router's LAN IP address ('''192.168.1.1''' by default) into your browser's URL bar and press "Enter". Next, type in the router's login information (user name: '''admin'''; password: '''admin01''' by default) and click "Login":

In the next window, type in the user name '''root''' and press "Enter". Then type in the router's password (same one you used for logging in to the router), press "Enter" and you should be greeted with a window such as this:

To login to a RUTxxx router via SSH, download the free '''PuTTY''' app if you're using Windows; if you're using a Linux based OS, just use the '''Terminal''' app. In both cases you will need to know three things: the router's LAN IP address, user name and password. The default LAN IP address for all RUTxxx routers is '''192.168.1.1'''; the default login information is user name: '''root'''; password: '''admin01''' (NOTE: the user name used for SSH connections (i.e., root) is not the same as the user name used to login to the router's WebUI (i.e., admin)).

If you're using PuTTY, enter the router's LAN IP address into the '''Host Name (or IP address)''' field, select SSH Connection type and click '''Open''':

* In the next window type in the user name, press "Enter", type in the router's admin password and press "Enter" again. You should be greeted with a message such as this:

After this you will be prompted to enter the user name and password.  

Once this is done, you will able to execute commands via SSH.

If you're using Linux, open up a new Terminal and type in this command:

* '''Linux''': open a new Terminal window, type '''ssh [email protected]''' and press "Enter". If this is your first time logging in, you might be asked to clarify whether you really want to login. In that case, just type '''yes''' and press "Enter". Then type in the router's admin password and press "Enter" to finish the login process:  

 

# ssh [email protected]

 

If you made changes to your router's LAN IP address or login name, replace the relevant data in the command above so that it is correct for your specific case. After executing this command you will prompted with a query that says "Are you sure you want to continue connecting (yes/no)?". Type '''yes''', press "Enter" and type in your router's admin password. If everything went successfully, you should be greeted with a window such as this:

This method is useful when sending short emails. As an example, lets send an email containing the message "'''Hello, JustTesting'''", from the hypothetical address '''[email protected]''' to '''[email protected]''' using Gmail's SMTP settings:

This method is useful when sending short emails. As an example, lets send an email containing the message "'''Hello, JustTesting'''", from the hypothetical address '''[email protected]''' to '''[email protected]''' using Gmail's SMTP settings:

  :~# echo -e "subject:Test\nfrom:[email protected]\nHello,\n\nJustTesting" | sendmail -v -H "exec openssl s_client -quiet -connect smtp.gmail.com:587 -tls1 -starttls smtp" -f [email protected] au"[email protected]" -ap"senders.email.password" [email protected]

  :~# echo -e "subject:Test\nfrom:[email protected]\nHello,\n\nJustTesting" | sendmail -v -H "exec openssl s_client -quiet -connect smtp.gmail.com:587 -tls1 -starttls smtp" -f [email protected] -au"[email protected]" -ap"senders.email.password" [email protected]

Let's examine this command in detail. First, this part:

So in short, the part beginning with '''echo''' and ending just before the column ('''|''') represents the email's header and body of text. Now lets examine the next part (the one that begins after the column):

This next method is superior when sending longer messages. Instead of using the echo command, we'll store our email header and body information into a text file. Just as in the example above, let's send an email from the hypothetical address '''[email protected]''' to '''[email protected]''' using Gmail's SMTP settings, but without using echo:

As you can see, instead of echo, we're using <span style=color:red>'''</tmp/mail.txt'''</span>, which is the path to the '''mail.txt''' file that stores the email's header and body. This file does not exist in the router, therefore, you should create it yourself. To create a file, use the '''touch''' command:
