Troubles in Virtual World

Feb 24

Posted by ejs in *NIX | No Comments

For testing OpenOffice.org i’ve set up a VirtualBox, running Debian/testing in x86and amd64 architectures.
In some cases, mouse integration does not work correctly. Although mouse works perfectly in the Guest window, it’s impossible to move it out without pressing Host key (left Ctrl in MS Windows).
VirtualBox guest additions are installed, guest resizing and shared folders works perfectly.
The solution was found in VirtualBox forums :
/etc/X11/xorg.conf must contain

Section “InputDevice”
Identifier “Configured Mouse”
Driver “vboxmouse”
Option “CorePointer”
EndSection

note two lines: vboxmouse tells X.org to use mouse driver from VirtualBox guest additions, and CorePointer instructs to use this pointer as primary. Without CorePointer line the vboxmouse driver is used, but it’s still impossible to move it outside guest’s window.

Unknown column ‘tplname’ in ‘order clause’

Found an error when deploying GLPI plugin “Generic Objects Management” v 1.1.3 from https://forge.indepnet.net/projects/show/genericobject/

I could add and modify object types, but was unable to add objects. Clicking “Add” button did nothing.

Uh.

Switched GLPI to debug mode and found “SELECT * FROM `glpi_plugin_genericobject_…` WHERE is_template = ‘1′ AND FK_entities=’0′ ORDER BY tplname 0.001 Unknown column ‘tplname’ in ‘order clause’ ” near the bottom.
Of course, the was no ‘tplname’ field in the DB.

A quick search in the sourse revealed:
the apropriate database is created when object’s type is created;
the function “plugin_genericobject_addTable($name)” resides in “inc/plugin_genericobject.objecttype.function.php”

$diff -u plugin_genericobject.objecttype.function.php.orig plugin_genericobject.objecttype.function.php

‘tplname’ field should be altered in “plugin_genericobject_enableTemplateManagement” function, but for some reason it isn’t.
That’s all.

How to start multisite Gallery2 on Debian

Jul 11

Posted by ejs in *NIX, My job | No Comments

I had a little disc and database crash, so the site was not updated recently.

Well, Wordpress was updated easily, but i had problems with Gallery2.

I need a multisite deployment of Gallery2. Although it is supported from the installer, some important steps are missing.

In order multisite Gallery2 to work, you will need to add some symlinks to every deployment of the Gallery2:

The site was down. Why?

Jul 1

Posted by ejs in Uncategorized | No Comments

Actually, it wasn’t down. Just the information was not displayed.

The reason is simple – after a prolonged migration to Atom MoBo, data crash in one of physical discs, loss of some MySQL databases, a new Wordpress installation was missing the theme i’ve used. So, quick edit in ‘options’ table, replacing ‘option_name’ ‘template’ and ’stylesheet’ with walue ‘default’ made the trick.
As you see, the blog is up and running again.

It happens

Weekend project – USBasp

Sep 21

Posted by ejs in Hobbies, programming | No Comments

I had some ideas to go out before, but as i got terrible cold last Friday, I had to postpone all of them.

I feel a bit better today, so decided to build USBasp – an USB port ISP programmer for Atmel product family. I used STK 200/300 dongle before, but it works from parallel port only.
USBasp: fresh PCB
Lets start: the schematics is from http://www.fischl.de/usbasp/ . You can find some schematics and pre-routed PCB’s there.

What I need is USB B type or MiniUSB connector, SMD parts, small footprint, single – sided PCB. The one I liked is by Thomas Pfeifer, http://thomaspfeifer.net/atmel_usb_programmer.htm. The problem is I found no files for Eagle there and had to re-create the PCB.

Additional features are:

  • RC filters on MOSI, MISO and SCK lines to suppress ringing, as suggested in AVR Freaks forum;
  • Signal from oscillator (XTAL1) is routed to the pin 3 on IDC connector via jumper – a handy feature to debrick the MCU if you accidentally fused external oscillator;
  • Inductor on the power line.

The PDF files with the layout are here, an A6 – size mirrored image for direct printing on OHP is here.

Added on 2008-10-01:
USBasp top side, populated
USBasp bottom side, populated
First, it works. Both connected directly or via USB hub.
Second: don’t create anything while you are ill. Actually, pin number 5 on miniUSB connector MUST be grounded, while pin number 4 can be grounded or left floating. I’ve used i jumper wire to solve the issue.

Hacking the FlexLM keygens

Aug 21

Posted by ejs in Hobbies, Software | Comments off

Ok, it’s ugly and illegal, i know. The information here is for educational purposes only.

Sometimes i’m asked to “cure” one or another product, protected by registration or network license manager, like FlexLM. And you know, a lot of keygens for these product found in the Internet, do not work. The usual error is “Internal Error #{1..6} – Please be sure the app is running and on the license screen!”. What’s wrong, why the keygens from the glorious crack groups do not work any more?

Search on the Internet revealed almost nothing: from “the kyegen does not work” to “it works perfectly”, some says one must use genuine windows the keygen to work (wow…).

Let’s start a little investigation. Read the rest of this entry »

Make Samba and CUPS in Debian friends again

Apr 15

Posted by ejs in *NIX | No Comments

I’ve seen a lot of these entries in logfiles recently:

[] printing/print_cups.c:cups_job_submit(656)
Unable to print file to - client-error-bad-request

And the printing is stopped, of course.

The solution is simple:

LANG=en_US.UTF-8 /etc/init.d/samba restart

In short:
/var/log/cups/error_log shows a lot of

E [] Unsupported character set "iso-8859-1"!

CUPS requires UTF-8.
In the case of default login in Debian, the console IS in UTF-8, but is not if you have customized it and use `su` for administrative tasks.

C’ia.
