How to popup a window on remote Linux desktop or make remote Linux to speak. In this post I will show you harmless tricks that can be really funny. Among helping, fixing and upgrading Linux systems there should be time for joking. So sit back, relax and open your terminals.
Before mplayer-gui installation in Fedora Core 12, you will have to add RPM Fusion repositories. After that, yum will resolve all dependencies and mplayer will be installed in a minute.
You can find a lot of backup solutions for Linux server. From expensive and multi platform software like NetBackup to simple BASH scripts. As a Linux (LAMP) administrator, I decided to write my own backup script in PHP. I wanted to backup important locations like Web root, crontabs, /etc, /root and copy MySQL dump files.
You can very easy enable Java applets in FireFox on Linux. In my case, I use Fedora Core 10 and FireFox version 3. Here are steps how to enable Java applets in FireFox …
rpm is a powerful Package Manager, which can be used to build, install, query, verify, update, and erase individual software packages. This is the first sentence in the long rpm manual that lacks examples. On the other hand, I will try to write nothing more but the rpm examples.
The “find” command is very useful. It can search the entire file system for one or more files that you specify to look for. With the “find” command, not only are you able to locate files, but you can also perform actions on the files it finds like move, delete, rename …
Files in Linux can be searched with “find” and “locate” command. “Find” exists very long, while “locate” is a new Linux feature. The main difference between them is the way they work – “locate” uses database to search files, while “find” searches for files in a directory hierarchy.
If you are a Linux administrator, then you certainly need tool to delete old files – especially old backup files or /tmp directory. Here comes tmpwatch. With parameter time and path, tmpwatch will recursively delete all files older then a given time. But if you use NetBackup, then you might have a problem with deleting files.
This post is second part of “Configuring VPN client”. After completion steps in previous post, VPN will work with starting pppd and manually adding route. With a few PHP lines and configuration of ip-up.local file, VPN connection can be automated and reduced to only one script.
After upgrade to the Fedora Core 10 and Fedora Core 12, I was surprised when ‘yum install mplayer’ didn’t find any package. I’m sure yum worked in Fedora Core 9 with installed Livna repository. I checked my Livna configuration once again, but there was no luck with mplayer. Something has definitely changed in the meantime.
In this post you can read how to configure the VPN client in Fedora Core 10. I tried to configure VPN client in NetworkManager, but there was no success. I turned off NetworkManager with chkconfig and uncheck Controlled by NetworkManager in system-config-network. In my case, VPN server is on Microsoft platform, so my domain name must precede the user name.
If your work is organized in a way to have all documents inside /home partition and e-mails on remote server then you have qualities for easy upgrade to the new Linux desktop. Easy upgrade means to have a fully functional Linux desktop in a few hours. Is it installation or upgrade? Well, technically I will write about installation, but it will look like an upgrade.
