FAQ
Q
What does the error pam_ck_connector(webmin:session): cannot determine display-device mean?
A
If you see this error in /var/log/auth.log , edit the file /etc/pam.d/webmin and change the line @include common-session to @include common-session-noninteractive . Then run /etc/webmin/restart .
Q
Free Web-Based Control Panel - Webmin 1.791 For Linux?
A
FOLLOW TIS LINK: " https://www.linuxhelp.com/free-web-based-control-panel-webmin/ "
Q
Can I run Webmin or Usermin under Apache?
A
This can be done with some configuration. See this document for details on running Webmin under Apache, or this page for details on running Usermin.

You can also run Webmin under the Zeus web server in a similar way. See this documentation for instructions.
Q
How do I run setup.sh?
A
After extracting the Webmin tar file, cd into the Webmin-1.890 directory and type ./setup.sh. Because the root user on many systems does not have the current directory in his path, just typing setup.sh will not work.
Q
How do I change my Webmin password if I can't log in?
A
Assuming you have installed Webmin in /usr/libexec/Webmin, you could change the password of the admin user to foo by running
/usr/libexec/webmin/changepass.pl /etc/webmin admin foo
