Webmin

Webmin is a web-based interface for system administration for 'nix systems which allows a user to setup user accounts, Apache, DNS, file sharing and more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and allows you manage a system from the console or remotely.

HOWTO: SSL Certificate

https://www.digicert.com/ssl-certificate-installation-webmin.htm

HOWTO: DISABLE:

SSL

sudo nano /etc/webmin/miniserv.conf
     ssl=0
sudo service webmin restart

HOWTO: FIX:

ERROR: Failed to open socket family 10

Error...

Failed to open socket family 10 : Address family not supported by protocol at /usr/share/webmin/miniserv.pl line 542

Fix...

This is because you are trying to start Webmin on a system without IPv6 support.

sudo nano /etc/webmin/miniserv.conf

ipv6=0

/etc/webmin/start

ERROR: SSL_ERROR_RX_RECORD_TOO_LONG

You will now get an SSL error on most web browsers, because the SSL self-signed certificate used by the standard installation is out of date. More information on the new SSL rules can be found here.

To fix it, regenerate the self-signed certificate, or install your own proper domain SSL certificate.

Incorrect Operating System Version Detected

Webmin behaves differently depending on the operating system or Linux distribution that you have installed, and the particular version that you are running.

The correct OS is always automatically detected at installation time or provided by the installer, but it is quite possible that your system may be upgraded during the lifetime of the system.

If this happens, Webmin will not automatically detect the upgrade - you must tell it by following these steps :

1. Click on the Operating System and Environment icon on Webmin > Webmin Configuration page.
2. Select your Unix vendor and version from the New operating system list.
3. Change the exact version number to match the detected version.
4. Hit the Save button to have Webmin start using it.
