Step 1.) Upgrade to Debian 11 first The process to go to Debian 12 is not as smooth as 11, when trying to upgrade from Debian 10. In fact, it doesn't work directly, so you'll first need to follow this guide to update to Debian 11, reboot and come back here if successful. Step 2.) Update sources.list Update your /etc/apt/sources.list like this: deb http://........

In this example we install debian 10 with --variant=minbase which gives us a minimal/tiny install. Don't use variant if you want the full size install. mkdir /tmp/deb10files debootstrap --variant=minbase buster /tmp/deb10files/ Did you get an error? debootstrap --variant=minbase buster /home/theuser/VMs/deb10files/ You'll get this error if you make a directory in your home........

The problem seems to be that whatever kernel and initrd you have is tied to an old version of CentOS 7 that is no longer in the current repos of most mirrors. If you were previously able to PXEboot and install CentOS and you are sure your network and tftp are good the problem is that you have an outdated kernel and initramfs that point to a defunct version.........

With ffmpeg it literally takes out what you want so you can use it later.

It has been a big pain for a long-time to install Windows from a Linux environment. I used to run a windows install server and it never worked right for some reason (the install would fail on most servers). Before getting start be sure to setup your samba share so once you boot into WinPE you can mount the install for whatever Windows you want /etc/samba/smb.conf [smbwinstall] path = /tftpboot/images/winstall guest ok = yes........

Very simple browse to your /boot directory It does make more sense to extract the image in its own directory eg "initramfs-blabla-dir" as it will literally extract directly to the pwd. cp initramfs.img someotherdir cd someotherdir zcat initramfs-3.10.0-514.el7.x86_64.img | cpio -idmv........

These errors believe it or not are simply because of not being the root user or running with sudo! However if you didn't know to try as root you'd think there was a problem with your burner or disc Essentially it looks like without root you cannot send the required scsi commands to continue writing. Ithink cdrecord should have built-in tests or safeguards to see if it has the permissions to run the required commands. I guess for more advanced users the idea is simila........

Ihave a tar and when extracting it changes /root to a uid and gid of the source server which is bad especially for /root! You can get around this by extracting as follows: Add the -o switch which means "--no-same-owner" tar -o -zxvf sometar.tar.gz........

Ifigured out what caused this but don't have the solution just yet. Iwould deploy a certain script from a .tar.gz to some servers and found that /root was always owned by user and group "1000.1000". This corresonded to the user who made the .tar.gz. For some reason when extract normally with "tar -zxvf file.tar.gz" it impacts the parent directories ownership. There must be some recursion going on or possibly the .tar.gz but I haven't f........

Disclaimer, before starting this I do not like ioncube, it is great to protect your source code, but a big pain to setup this extension since it has to be done manually.

It's always bothered me how Wordpress basically forces the user to provide their hosting credentials to install themes and plugins. How do know for sure the data is not being saved, intercepted and being provided backdoor access to the NSA or other agencies or even just being misused by others with access? Here's how to close the security hole above and if you're already given Wordpress your credentials make sure you change everything associated it with it. Eg. change your........

One thing to remember is that you need MegaCli to do the flashing. You also need the correct file,I tried at least 2 different Perc 6 firmwares from Dell that kept getting rejected as corrupt by MegaCli(they were really the wrong version). I have an external PCI-E Dell 6 Perc/I butI chose images from the 'Integrated" on motherboard version as it was allI could find. They are different, and below is my first time finding success.........

LSi Megaraid At first it was configured as a RAID 0, then I deleted the Virtual Disk Group. I thought both drives would be shown and detected in Linux as sda and sdb but it actually shows nothing. To make them work you have to hit Ctrl+R before the system boots (when prompted) and create a Virtual Disk Group. In my case I created each one as RAID 0 (with a single drive only) as I just wanted JBOD but there is no such option or default in these Dell Pe........

start=1 increment=5 lines=`cat linesfile.txt|sed -n "$start","$increment"p` The secret here is the power of sed. Basically the example above would take the first 5 lines from the file.

It is desirable to strip the leading slashes when taring / because you wouldn't want to overwrite your entire system when extracting some files to check. But if you are restoring / from the tar you want the leading slashes added again. Here's how to do it: --absolute-names -P Either one above will do the same thing.........

Everyone says there is a "manual" way of doing it and then they tell you to use iTunes, but if you're like me, you're travelling on business in a foreign country and your laptop does not have iTunes and you don't have a way of getting it and/or don't want it. For this example I'm using the provider "du" in Dubai, UAE (United Arab Emirates) but this method works for virtually all providers. The requirements in this case to truly "manually update........

There is a tool called "xml2" which will parse both HTML and XML scripts, this is very useful to do a mass extraction or conversion of data based on say an HTML table etc..
