How to Disable SSL for Webmin

Webmin is a Web application that enables administrators to manage Linux servers. Webmin runs on a Web server at port 10000. Miniserv is the name of the Web server application that handles the Webmin Web application. By default, Miniserv uses SSL. However, you can disable SSL for Webmin Miniserv by editing the configuration file for the Web application. With SSL disabled, you can access the Webmin application over a standard HTTP connection.

Step 1
Open a terminal window on the Linux server. You can also SSH into the server if you do not have physical access to the machine.

Step 2
Type the following command at the command prompt and press the “Enter” key:
nano /etc/webmin/miniserv.conf
This command opens the Miniserv configuration file in the Nano text editor.

Using SSL with Webmin Fix SSL error

SSL Error On First Access of Webmin on New Install - (Error code: ssl_error_rx_record_too_long)

If you try to log into a new install and you receive this error:
An error occurred during a connection to xxx.xxx.xxx.xxx:10000.
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)
It is because SSL is not configured for Webmin and it must be enabled.
Solution:

Because your Webmin login and password are normally passed between your browser and the server in unencrypted form, an attacker with access to any of the networks between the browser and server can easily capture your Webmin login. To prevent this, Webmin can be configured to use SSL to encrypt all of its network traffic.

If you have yum support on your linux distribution following will resolve SSL issue.
yum install openssl openssl-devel perl perl-Net-SSLeay perl-Crypt-SSLeay

Else follow below method.
