As per this serverfault answer, use the following syntax:

1. Run this:

2. Login to webmin at https://localhost:10000. Expand the group Webmin, then Webmin Users.

3. Create a group call “WebminRootUsers” or the like. Click through and allow that group access to as many Webmin modules as you like.

4. Create new webmin users, and add them to the newly created group.

5. Test that the new user accounts work.

6. sudo vim or sudo gedit /etc/webmin/miniserv.users, the line with root should look like “root:x:0″ (which is the default).

If you are receiving a “HTTP Status 500 Internal Server Error” when trying to Edit or view a Gallery2 setup, you would ought to check whether your choice of graphics toolkit is the cause of the error.

In a gallery I was setting this morning, the “Gd” graphics toolkit was causing the site to crash because of a time-out which arose when Gallery2 attempted to use Gd to generate a thumbnail.

The fix is to fight your way to the Admin/Plugins page, configure and activate the ImageMagick plugin, and deactivate (& delete) the Gd plugin.

Incidentally, the only way to trouble-shoot Gallery2 when it is in this condition is to:

1. Check your host’s error log for any errors generated by the PHP scripts and/or Apache; and
2. Activate Gallery2′s immediate debug mode.

Immediate debug mode should at least generate output, the last line of which should indicate where/why Gallery2 has died.

Finally, if you are running on a Linux Host / LAMP stack and you want to use a local php.ini, you must put the following line in the  .htaccess file:

I have been using an Epson TX110 for all of my at home printing needs for about three years. While its scanning function is good, I am absolutely sick of the way I need to keep on replacing colour cartridges even though I only ever print in black and white. My colour usage has, in fact, almost entirely been taken up by routing cleaning of the printer heads.

So, rather then spend another dollar on colour cartridges I will never use, I finally bit the bullet and purchased a laser printer.

Being a linux-geek, the first thing I did was connect it to my home server and share it with my laptop and desktop.

The next thing I wanted was the ability to link the scanner function on the Epson TX110 with the Brother laser printer, to be able to quickly photocopy a page. This is amazingly easy with bash and the right tools installed:-

All that remains is to have the ability to scan documents to PDFs…and again, bash and the command line comes to the rescue…you can download my scanpdf.bsh. It is designed for flatbed only scanners. Try running it with --help to see available options. You may click here to view the code.

Take note of the “DISPLAY” variable, this is the local port (on the machine called “desktop”) which is forwarding X11 server commands to the X11 client running on the machine called “laptop”.

This sets the “DISPLAY” variable to the first screen on the desktop, and starts VLC as a background process. For this to work you must be logged into the server with the same user account, and have an X11 client running on the desktop.

This sets the “DISPLAY” variable to the laptop, and starts Gedit on the server, but displaying it on the laptop.
