View 3 Replies View RelatedI am looking for c/c++ code (no third party lib dependency) to get the physical address of ethernet card on mother board.Most of them suggests to use the linux commands and process the output. For example "/sbin/ifconfig eth0".The problem with above command is that when you run this on a linux variant which is running using VirtualBox on windows host, it's not returning the correct mac address. In this case the correct mac address is the one set for individual virtual machine."/sbin/ifconfig eth0" works fine when linux variant is installed normally.There is another case when linux variant is installed normally and if you install virtualization apps such as VirtualBox or VmPlayer, they create a virtual adepter for their own use. In that case running "/sbin/ifconfig" returns all the adepters. (physical and virtual)

Starting from the operating system to the programs all was backed by a closed company.EurekaAt the year 2004, I have read a magazine that mentioned the word "Linux", it was the first time I got to know that actually there was other Operating Systems than Windows. I "googled" and "wikipped"(searched), all the information I could get about that new system(for me).
After few searchs the word "Debian GNU/Linux" came up. I have burned the ISO file for a brand new CD and got all enthusiast.ExperienceI had actually complete the command line install, but always thinking for myself "What a waste of time!" (Yeah... such an idiot I was at that time).
After the installation, I booted the distribution and at the minimal error and/or thing that didn't worked like I pretended, I would just say a lot of terrible things and give up.The second chanceOnly at about 2007, I gave Linux other chance(ironic, like Linux was the guilty for my lack of skills. I downloaded and burned the Ubuntu Linux 6.06 Live CD ISO.
I was astonished when the CD booted,
asked for language and actually changed it.
Then the Live Environment "flashed"(appeared).
I was out of words and almost regretted everything I have said about Linux efforts(I still didn't had a open mind tough). For the first time I actually faced-up the problems and issues that came up, but annoying everyone and saying bad stuff(I'm terribly sorry).The enlightenmentOnly at about end of 2009, I started actually wanting to learn how everything worked. That was the time I changed for Slackware Linux distribution. I learned many stuff. But with the time, I realized that the important isn't the Operating System and/or Distribution we use, is the use that we make of it. Nowadays I use about any distribution without complaining much. We need to respect the work of others after all, and we can learn with the mistakes too.
All this to askThe questionDo you think the registration of Linux users can make people, companies, governments, institutes, and everything related to technology change their opinions (minds)?NOTE: This reflects for BSDs, OpenSolaris(now over) and all other related open source software not just Linux.

We are virtualizing our data center. We have a total of 23 HP blade units (2-sockets each) that will have hundreds of potential RHEL 6 virtual machines running on them within VMWare. All of these VMs (Set 'X') will need to have rhn_register run on them so that patches and updates can be routinely applied. A subset of X - call it set 'A' - of these VMs will require 12x5 support (Standard Support) from Redhat. Another subset of X - call it set B - which is mutually exclusive from set A, will require 24x7 support. For any given server, we can not yet identify which will be in Set A, Set B, or just in X alone.
If we decided we had no need for phone or web support, but wanted to be able to use RHN for patches, would purchasing one Self-Support entitlement for each VM suffice? We are probably looking at the Unlimited-number-of-guest-OS subscriptions. Is there any way to purchase Premium (24x7) support for some VMs and Standard (12x5) for others? Does the count have to be decided ahead of time, or can we decide on the fly?
In other words, can we wait until a VM crashes over the weekend to call Redhat and say "We need this VM on premium support" ? The motivation for this inquiry is that we don't have the budget to put 23 blade units' worth of VMs under premium, or even standard support. I'm curious how Redhat manages this, since subscriptions are done per physical server, not per VM. (When you're dealing with the unlimited-number-of-VM pricing.)
It seems whenever i create a folder it creates the folder as untitled folder, but i can't change the folder name it just says "you don't have permission to rename item" but yet i created the folder and it is there. One thing i have noticed is that once i enter a folder it won't even let me move the folder.

I've tried kwrite and mousepad and both have a search feature and a replace feature but I haven't been able to just have the text removed successfully.
