Linux migration tutorials

After several months of using Linux we found several ways to print on Linux including Windows Printer server...and REVOLUTION... now we found a ultimate driver :D We found that every PPD driver which have sufix "ljet4" will work on Linux. We usually use Samsung QL-5100A ljet4 driver which works on our KONICA MINOLTA printers. Before this our KONICA MINOLTA printers like 15490, 240f, bizhub c10, c352... worked only with Windows Print Server. Now Linux computers can send data directly to printer and it works perfectlly.

If printer is not working , and you need it, your system is almost unusable.

Because that we will now explain you how to setup ALL of printers you could have in your life.

If you need LAN communicator or intern communicator on which you can connect from internet, on which you can edit groups, rooms, users ... everything you need to do with instant messaging protocol... you should try openfire.

Her is full tutorial how to install/setup openfire on ubuntu 12.04. or 12.10 Tutorial is needed because openfire non-opendsource  java runtime , and that java runtime you can't install without some tweaks.

If you are one of many users who have one Windows computer in LAN and lot of Linux computer and lot of printers which don't work with Linux we have solution.

After some googling we found page that explain how to print on Windows printer from Linux machine without any driver or PPD needed. You can red it here. But it is to hard to confiugure for most of users, it supports only one printer on one computer, and it is hard to manage. We created program which is doing same thing much better and easier.

If you have remastered Linux with included TeamViewer or if you cloned your Linux distribution and all programs and setting you will be faced with problem that all your cloned, preinstalled machines will have the same ClientID number.

You can solve this easily by removing teamviewer settings.

Open terminal and enter this command: rm -r ~/.teamviewer

It will delete all teamviewer setting , but they will be back after you start teamviewer, and there will be new ClientID. Sometimes you must wait several minutes to gain new ID number and password.

If your Openfire chat server stops after few days and says "Out of memory" you have several thing to do, some of them solved problem, but if you do it all and update Openfire it should stop showing error.

1. Add system property: cache.username2roster.maxLifetime = 419430400

2. Add system property: xmpp.pep.enabled = false

3. You can increase memory for Java. Add a line like this in file /etc/sysconfig/openfire : OPENFIRE_OPTS="-Xms256m -Xmx512m"

You can increase memory as much as you can, so if you have 2GB of memory you can set: OPENFIRE_OPTS="-Xms512m -Xmx1024m" .

If you want to use BIRT reporting as alternative to Microsoft SSRS you can easily do it by instaling BIRT on any linux distro. There are several tricks you have to do before everything will be fine.
