    [Zorin] Re: no boot linux

    Sorry. I don't know. My Ryzen isn't setup to use UEFI booting, nor does it have an AMD GPU.
    Doesn't UEFI have a tool that allows selection of the boot init file to be used? efi-manager? Something...

  4. [ubuntu] Re: Should backup drives be password protected (LUKS) & can you protect an existing d

    It is important to learn to think like an attacker would, at least for the obvious attack vectors.


    Well, it does in that the data can't be stolen. But it does NOT because if the data can be...

    Re: Can't extract tar.bz2 file

    x/l/c - extract/list/create
    v - verbose
    z/j - some sort of compression
    f - file ... the next argument that follows is a tar filename of some sort.

    Both of these are the same:

    Part 3

    Security professionals suggest using IPSec-based VPNs with 2FA. IPSec is part of the IPv6 standard and has been available and working for over 15 yrs. Android and iOS clients have native...

    Re: Use of VPN in our Brave New World

    Part 2

    VPNs that only use usernames and passwords are not very secure.
    SSL-based VPNs aren't usually secure against state-level monitoring, unless they use TLS 1.3. Earlier versions, including...

    Re: Use of VPN in our Brave New World

    Seems the forum software here is still broken. I'll try splitting my reply up.
    Wikipedia provides explanations for what a VPN is.

    That's part 1.

  11. [ubuntu] Re: chmod to give a remote server read priveleges to a client home directory

    ssh key-based authentication is not just more secure. It is more convenient. I don't understand why everyone doesn't just use keys instead of passwords. Makes no sense to me. Being prompted once per...
  12. [ubuntu] Re: Failed to probe capabilities for /usr/local/bin/qemu-system-x86_64: internal erro

    I like to keep it simple:

    KVM acceleration can be used

    Whatever is pointing at /usr/local/bin/qemu-system-x86_64 was probably installed outside the package...

    [ubuntu] Re: I did something wrong with 20.04]

    300 emails isn't a DoS attack. 30,000 wouldn't be a DoS attack, unless you are on a 2400 baud modem.

    Probably want to open a new thread for these questions, since they aren't related to fsck.
  15. [ubuntu] Re: Should backup drives be password protected (LUKS) & can you protect an existing d

    Yes, having data on encrypted storage is a "good practice." Just be 100% certain you have at least 3 copies of the data on different physical storage.

    Encryption only helps with protection when...
  16. [ubuntu] Re: chmod to give a remote server read priveleges to a client home directory

    chmod works on the local machine or over NFS mounts. There is no remote version of the command.
    If you ssh into the remote system, the chmod commands are "local" to that remote system.

    Any errors? Might be useful to throw the output to a log file and review the logs. That would be :

    For disks, there are lots of tools.
    smartctl, fdisk, badblocks are the main ones. Avoid GUIs. They lie. They often oversimplify way too much and provide misleading output.
