  • Linux How To Access Original Contents of Directory Mounted Debian Mint CentOS Redhat Solution


    Let's say you have a directory /mnt/raid which has files and directories inside it, but nothing is mounted to it. Then you mount a block device such as /dev/sdh to /mnt/raid Even though /mnt/raid has files and directories there, you can only see the mounted contents of /mnt/raid. How do we access the original contents? Just do a bind mount of the root filesystem to another location. mkdir /bindmount mount --bind / /b........

    The display manager is more so what controls the main graphical login process after Debian/Mint/Ubuntu boot and controls the graphical login sequence.

    This is sure simple if you follow the guide but it took a lot of hacking around to make this work on Debian/Ubuntu! Now before you ask why bother running wine and python, the reason is because Python executables are NOT cross-platform. If you run pyinstaller in Linux, that binary will only run on Linux and the same if you do it in Windows. So it is preferable if you have a single environment that you can create Linux and Windows binaries from rather than running 2 separate........

  • How to avoid web content hijacking/copying/Force content to be accessed by only 1 domain name


    This is something that happens a lot and it is very dirty, as you probably know each site is hosted on a certain IP address. Sometimes a domain is hosted by a single IP address and the IP address defaults to this very same domain. This means that if someone buys domain abcd.com and enters your IP address (the one of your website) as the A record, your content will show up on their domain as if it was their own.
