    Re: Linux "image"

    In the puppet training, they asked a room with 200+ people how many had puppet maintaining their entire environment 100%. 3 people, all from the same group, raised their hands. They'd taken up...

    [SOLVED] Re: Why does Postfix need to use an SMTP relay?

    587 is for client -to- server SMTP transmissions. No ISP should be blocking that. Thunderbird and MS-Outlook and probably every other thick email client support that port for sending authenticated...

    Re: Linux "image"

    The cobbler infrastructure to push installations to other systems doesn't work on 20.04 Ubuntu. A CentOS or RHEL server is needed for that. I know the Ubuntu devs have a bug open about that...
  4. [ubuntu] Re: Ubuntu dmraid ONLY show 1.6TB in 8TB mirror

    MSDOS partition tables only support 2TB. To get beyond that, a GPT partition table is required. That's my first guess. It might not be correct.

    sudo fdisk -l will output the partition...
  5. Re: Ubuntu 20.04 - Creating /home partition after a LUKS installation

    You should know that the installer with LUKS encryption will also include LVM, so you'll need to learn that as well. LVM is a "Logical Volume Manager", so a single partition will be created and LVM...

    Assuming the posted conf above is correct and the ONLY file in the /etc/netplan/ directory, there are some clear issues.

    Re: OpenVPN and SSH

    Typically, carrier wireless/wifi APs hosted outside your home do not allow inbound connections.

    Any inbound connection requires each network device in the way to forward the required port to the...

    Re: Cloning xubuntu ...

    When device names change, cloning means both grub and the fstab and perhaps some other disk mounting settings will need to be updated manually. Only the OP knows his skill level for these things.

    [SOLVED] Re: Why does Postfix need to use an SMTP relay?

    If your server is on a DHCP range of IPs, then it will be blocked by almost all reputable email servers. You'll need to use the ISP-provided relay. The ISP will likely block all outbound port 25/tcp...
  10. [lubuntu] Re: Copying system setup from on machine to another?

    Re: Mounting drive as an existing folder

    That guide isn't for zfs and is 11 yrs old. ZFS mounts don't use the fstab.
    Suggesting 777 permissions causes repercussions that many people wouldn't desire.

    [xubuntu] Re: Increasing KVM network interface to 1Gbps

    I don't know what, if anything, netplan improved. For the last 10 yrs, most Linux changes have seemed to be about developers chasing "the new hotness" for CV padding. Many changes with reason were...

    Re: Wireless network solution

    No. USB Wifi adapters are NOT routers. They are for laptops that have a broken wifi adapter or for a desktop computer that doesn't have wifi, but you wish to add it.

    You need a new router, if you...

    Standard support for 16.04 Server ended in April. If there are any issues, it hasn't been worth figuring those out on that release for about 6-12 months.

    Re: Linux "image"

    The hardware involved will determine much, as will the exact ubuntu release used as the base.

    If you are trying to run a VM on ARM, the answer would be very different than running a VM on AMD64. ...
  19. Re: SELinux. Unable to get valid context for but user loged via ssh.

    SELinux isn't normally used on Debian-based Linux. Apparmor is. You'll find very little help with SELinux on Debian/Ubuntu because 99.99999% of us use something else.

    Re: Full Screen, Ubuntu Guest VM on Ubuntu Host

    Inside the VM, use any display resolution control tool that you like. I use lxrandr because it is bonehead simple.
    It is always best to run at the monitor's native resolution.

    Perhaps.
