  1. [ubuntu] Re: ubuntu server failed to start network time syncronisation

    If you have no network interfaces, that's the problem, and it's much bigger than just time sync.

    18.04 uses netplan, not /etc/network/interfaces, to activate interfaces and assign them IP...

    Re: Will using iptables secure Ubuntu?

    First, about the localhost address. Yes, I forgot to exempt it in the rules above. It's easier to write a rule that exempts the "lo" interface like this:

    Re: Will using iptables secure Ubuntu?

    First, out of the box, Ubuntu has no services that listen on ports. So it's largely invulnerable to most attacks.

    Does the machine present a publicly-visible interface? Does anyone other than...
  4. [ubuntu] Re: Brother Laser Printer HL-L2340DW, wifi

    I strongly suggest hard wiring the printer to your router with an Ethernet cable. Then give it a static IP address within your network subnet.

    Re: php failure: Text File Busy

    Make sure you have the opening and closing PHP tags in your script. It should look like this:


    #!/usr/bin/php
    <?php
    PHP code here
    ?>
  6. Re: Which would be the best domain name?

    I'd start by searching in the .com and .net domains myself. Like TheFu says, top-level domains like .systems raise suspicions.

    There aren't many options in .com, but I did find that...
  7. [ubuntu] Re: ubuntu server failed to start network time syncronisation

    Let's see the results of these commands:



    date
    sudo hwclock


    You could make your server an NTP server by installing the ntp package. Then it will synchronize itself with other Internet...
  8. Re: looking for web connected phone sevice

    You can buy an interface device that will let you use Google Voice from regular telephones. I've been thinking about replacing my landline this way.

    For instance,...

    I'm on the planning committee for the 50th Reunion of my college class a year from now. As you can imagine, we're considering methods to convene virtually if necessary including live streaming of...
  10. Linux software to control my Logitech web cam?

    I switched over to Windows today for a Zoom call. Before I did so, I installed the utility application from Logitech to control my camera (a 9000 Pro, I believe). That allows me to pan the camera...

    Re: zoom cpu usage

    Are you hosting these sessions? How many participants? In our experience the host's bandwidth and computing power can matter quite a bit.

    If you're hosting a 200+ participant meeting, I'd...

    Those permissions do grant full access to all users as the MySQL complaint indicates.

    [ubuntu] Re: i do not have cd rom anymore

    Remove, or comment out with a leading hash mark ("#"), the CD-ROM entries in /etc/apt/sources.list.

    Most of these problems come from the fact that 19.04 ("Disco Dingo") reached end of life in...
  16. Re: Adding a Second Router to Home Network

    You can daisy-chain the routers by connecting the WAN port of the second router to one of the LAN ports on the first router, then giving it an address in the first router's network, 192.168.1.0/24 in...
  17. [xubuntu] Re: Is it possible? Clone a Windows 10 to an SSD in the same machine?

    I don't know if cloning will work; never tried it myself. But you could download a brand-new ISO image of Windows 10 and install it on the SSD if you still know what your Product Key is. (Most...

    You might want to check the integrity of the btrfs filesystem. If a filesystem has errors, Linux will mark it read-only. Can you write other files to that filesystem using the same username as...
  19. Re: Nextcloud, Apache & Letsencrypt in Ubuntu 18.04 server

    NIce. My servers run CentOS 6 so they're not using systemd. At the time I created them at Linode I didn't want to deal with that, so I stayed on an earlier release.
  20. Re: PDF Looks/prints great on Windows, but is wrong on Ubuntu

    What about GIMP? It will import PDFs.

    As for the background, I wonder if it might be a mismatch between the RGB and CMYK color models. I bet Avery uses the latter. If this is the issue, you...

  23. [server] Re: Ubuntu Server 19.10: WOL not working

    Are you building a server with WOL? My servers are always available 24/7. To my mind, that's part of the definition of a "server." Usually WOL is a client-side technology.
