  1. Re: bricked Ubuntu server 20.04 "sudo chmod o= /"?

    This is going to be a mess to fix and you will probably better off just backing up your data and then reinstalling the OS.

  2. [ubuntu] Re: Restoring the DD image of Ubuntu 18.4 LTS is not booting up

    Do you know how the dd image was originally generated?

    If you've already tried to reinstall grub that way, you could always try the old "tar everything and then restore it to a different drive"

  3. [ubuntu] Re: Is there any need Firewall software for Home PC ?

  4. [ubuntu] Re: Restoring the DD image of Ubuntu 18.4 LTS is not booting up

    How did you try installing grub?

    Like this?


    sudo grub-install /dev/sda
  5. [ubuntu] Re: Is there any need Firewall software for Home PC ?

    Same. All I've gotten when I've run ClamAV is false positives.

    The same can be said for other AV too.
  6. [ubuntu] Re: Restoring the DD image of Ubuntu 18.4 LTS is not booting up

    That's good at least.

    Do you already have /boot ?

    If so, try running the procedure here:

    Re: How to modify the router MAC address?

    In addition to what TheFu has said. Some routes have a "clone MAC" option, but that would need to be configured on the router itself.

    Here's what the man page shows about that command:

  11. Re: Did someone log into my PC and edit auth.log entries to cover tracks?

    Agreed on the encryption bit. It's a layer of extra security, but it does have it's down sides as well.

    If you are in this sort of situation, enabling two-factor authentication can help immensely,...
  12. Re: Did someone log into my PC and edit auth.log entries to cover tracks?

    Do you have VNC or Remote Desktop or SSH enabled?

    Is the gap in the logs the only reason you suspect someone tried to access your machine?

    That is the part of how the domain registry itself handles expired domains and grace period that is in place for some domains.

  15. Re: SUGGESTION to make it possible on all ubuntu to select install location

    That's what it sounds like.

    I know you can compile stuff yourself and stick it in /usr/local or ~/bin, but that's as much of the "store programs separately" that you can get without breaking...
  16. Re: looking for kvm qemu drivers for a winxp x64 guest

    XP x64 didn't have very good driver support, so it's unlikely you'll find a driver that works.

    You could have a read here, but it's probably only related to XP x86....

    Re: i need find a new mail program

    Do you have any addons installed? If one of them was updated, that might explain the loss of the send button. Or perhaps it's profile corruption - I've seen that with firefox, but not Thunderbird...

    Do you mean that you want to be prompted for your passphrase before the system completes booting?

    You are able to run full-disk encryption via LUKS on Ubuntu, but as far as I am aware, you still...
  19. Re: TOP is showing strange output and something is eating memory

    Seconding the "that's not normal" bit.

    [ubuntu] Re: Open port Why?

    Hi,

    master is the name of the process and it's probably related to postfix or exim, which are both mail servers.

    They can get installed as a dependency if you install something such as...
  21. Re: Are you using a Microwave oven ? What recipes do you cook using your microwave?

    I don't really cook stuff in the microwave, but I've been spoiled by my air fryer.

    [server] Re: Allow SMTP on Server

    I don't know if this helps, but googling "The server response was: UGFzc3dvcmQ6" returns that "UGFzc3dvcmQ6" is base64 encoded version of "Password:".
