• How To Upgrade Debian 8,9,10 to Debian 12 Bookworm

    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://........

  • How to extract view contents of initramfs image gzip'd

    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........

  • How to see what's inside your gziped CPIO'd initrd image

    Copy the initrd to somewhere else, say /tmp: mv initrd.img to initrd.gz *the mv to .gz is needed otherwise gunzip won't work/it will refuse to operate without the correct .gz extension gunzip initrd.gz cat initrd | cpio -idmv The last command extracts the contents of initrd to your present working directory.

  • yum in Centos 5/Xen halts and exits suddenly

    yum exits in the middle The problem is this VPS seems to be an OpenVZ template from HyperVM. The only way to make it work was to disable i386 packages since this was an x64 kernel. That shouldn't be necessary but it was the only way to make yum stop quitting after the first package or two. I couldn't find any issue by checking the logs either. echo y|yum install vim-minimal telnet expect jwhois net-tools slocate iptables elinks gawk L........

  • tar gzip: stdout: File too large - Error Size Limit on Large file > 17GB

    The folder I was trying to archive is about 72GB, but much like rsync at about 17GB it chokes because of the filesize. What's with so many common and essential Linux tools having such limitations? I guess it is likely that the authors never wrote their code with the idea that files would be so large but it's still very annoying. It's important to stay on top of these limitations on production servers because I didn't realize what happened until I checked the file with "........
  • OpenVZ backup container to a single file while it's running using "vzdump"

    Proxmox has made this free utility to backup running OpenVZ containers. It's a great program which is actually just a PERL script but gets the job done. This program is not 100% required because all it really does is cp -a from your container's path as far as I know but it is still good to have uniformity to how you backup your containers. For RPM distros such as Centos/RHEL/Fedora etc.. download and install this: wget http://www.proxmox.com/cms_proxm........
