• How to Spider the web archive.org to recover your old website/webpage


    There are problably a million blog posts telling you how to do it, but none of those guides worked for me. Things can often be different sites and other "unknowns", so there is no guarantee this works for you or for every site. First we'll use curl to search for all the relevant files for the domain and based on the snapshot/timestamp in bold below. curl -s "https://web.archive.org/cdx/search/cdx?url=yourdomain.com/*&to=2........
  • E: The repository 'http://deb.debian.org/debian buster Release' does not have a Release file. - solution Debian 10


    If you find yourself updating an old Debian/need to upgrade and get this error, generally you just have to update sources.list by setting all hostname references to archive.debian.org Backup your sources.list cp /etc/apt/sources.list /etc/apt/sources.list-bk Change deb.debian and snapshot.debian sed -i s/"deb.debian"/"archive.debian"/g /etc/apt/sources.list sed -i s/"snapshot.d........
  • Cloned VM/Server/Computer in Linux won't boot and goes to initramfs busybox Solution


    This is mainly for if you've done something silly like trying to clone a Live, running VM image. In this example, the VM initially finds grub and tries to boot but is kicked straight into initramfs rescue mode/busybox right after this. If you've done this "silly" thing, you could have dataloss but a lot of times just using fsck will fix it as you are guaranteed at best to have some corruption and inconsistencies in the filesystem. My theory is that some files wer........

  • kvm cannot boot xen guest using lvm


    This booting error is because the Xen PV guest image uses the Xen kernel, this is not compatible with anything but a host running a Xen kernel. I did a kpartx -av virtual.img and then it created some partitions that showed up in fdisk. I mounted it and did a chroot into it and removed the xen kernel and installed a normal kernel but Xen still shows the same kernel in Grub (only the Xen one). This is strange but it seems like this Xen PV guest has some sort of hidden or........
  • Kernel/make compilation time and how to improve compile times/compile the Linux kernel faster without hardware upgrades


    I thought only a faster CPUand SSDwould help but I already have a Quad-Core CPU and it wasn't being maxed out. The actual tests were performed on an AMD-V enabled 128MB dual core VMWare container though. There is a flag that can be passed to make in order to start multiple threads, by specifying 4 threads I was able to reduce the whole kernel compilation time from scratch by about 50%! (65minutes vs 31minutes!). *Yes I did do a make clean before each co........

  • 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........
