  1. Re: Wi-Fi passwords suddenly not accepted (multiple Wi-Fi networks)

    I've encountered this myself. I found that rebooting the router helped.
  2. [server] Re: allow only 1 (not specific) IP at a time on a port

    In the good old days, I would wrap the service with xinetd to limit it to one simultaneous connection. Apparently systemd now offers this ability, but someone else will have to explain that method.

    Re: Resold Broken

    If you edit resolv.conf manually, chances are good the edits will be lost the next time you reboot.

    /etc/resolv.conf should read:


    nameserver 127.0.0.53
    options edns0

    and it may have a...

    Re: Adventures in Partitioning (Newby)

    More than enough. Currently my Kubuntu 20.04 machine is using about 2.6 GB of the 8 GB I have available. Most of the rest is being used as buffers and cache. Linux is quite aggressive about caching...

    Re: important operative systems.

    After BSD, MINIX and Linux, my list is short. MIT X/Windows gave *nix systems a powerful graphical interface. Apple chose the Mach kernel developed at Carnegie-Mellon as the basis for Mac OSX. MINIX...

    Re: Adventures in Partitioning (Newby)

    I'd put the OS on the SSD for performance reasons, though with enough memory there isn't that much disk activity in normal operation. Linux loads needed programs and libraries into memory; once they...

    Re: Adventures in Partitioning (Newby)

    In general, most users have no need to partition their drives for Ubuntu installations these days unless it's for dual-boot or multiple operating systems. I like to keep a couple different operating...
  10. [xubuntu] Re: Resource use of KDE apps running on XFCE

    I'm running the development version of 20.04. It's only using 1.5 GB of my system's memory with Brave Browser and Thunderbird along with a couple of other applications like Dolphin all running.
  11. Re: Choppy video playback of mobile phone video

    I'd remove the snap version of mpv then run

    sudo apt install mpv smplayer
    SMPlayer is a GUI front-end to programs like mpv and the older mplayer.

    [ubuntu] Re: migrating from old to new machine

    Anything under /home should constitute "personal" files.

    If you want to have the same software on the next machine as the old, you can use the command

  13. Re: Manually installing from a live distro by copying the system

    Use the installer, choose manual to assign the drive's partitions to the various OSs, then tell grub where to write the boot record. It will overwrite whatever was there before.

    You can't copy...

    Try installing testdisk from the repositories. If you run "testdisk /path/to/your.iso" it should offer to analyze that file.
  15. Re: Squid memory usage increase overtime, proxies slows down

    First, where is this Squid installation running? Is it on a gateway of some sort with a public-facing IP address? What address is 216.115.184.251? Is it yours? It doesn't have reverse DNS...
  16. Re: do you use live distros often and why.

    I use live installations when I need to do something with the hard drive in my systems. Most recently I've booted a live Kubuntu ISO and installed gddrescue so I can clone a machine's hard drive to...

  18. Re: Have You Used Pop and Ubuntu (and Mint)?

    I think effective support is a crucial to running Linux. i would not choose a distro that sounds as unsupported as you describe Pop to be.
