  1. [ubuntu] Re: CLAMAV not scanning .rar format files for heuristics

    I'm going to take a guess and say you probably need to install libclamunrar9 from the repositories. "apt-cache search clamav" returns libclamunrar9 with the description, "anti-virus utility for Unix...
  2. [server] Re: allow only 1 (not specific) IP at a time on a port

    If you use REJECT instead of DROP,

    sudo iptables -A INPUT -p tcp --dport 22 -s 0.0.0.0/0 -m connlimit --connlimit-above 1 -j REJECT
    the second connection will see

  4. [server] Re: How to Close Email Ports in Ubuntu 16.04?

    Unless you installed SMTP or IMAP software like Postfix or dovecot, there should be nothing listening on those ports, so there's no reason to close them specifically. Ubuntu ships with nothing...
  5. [server] Re: allow only 1 (not specific) IP at a time on a port

    Xinetd has a number of useful features. I use the redirect option to pass connections to an IMAP server running on a machine behind a public-facing server. The man page for xinetd.conf is quite...

    Re: FTP to web documents directory

    Openssh-server is not part of the standard installation for the desktop. It's included in Ubuntu Server. On a desktop you need to run "sudo apt install openssh-server".

    [SOLVED] Re: upgrade ubuntu 20.04 beta to final

    If you install 20.04 in the space that 18.04 occupies now, you should be fine. Kubuntu 20.04 has been pretty stable for me so far.

    I'd probably just go for a fresh installation rather than...
  8. Re: Tyring to install a 4TB hdd, problems.

    Open the drive with "sudo fdisk /dev/sdb" (my guess is it will be sdb). Use the "d" command repeatedly to delete any existing partitions. Write the results to the drive with the "w" command. Exit...
  9. [kubuntu] Re: install .deb and see list of unsatisfied dependencies

    There's a build of 5.2 at Oracle for 18.04 thru 19.04. I bet it will work on 19.10 as well.

    Re: FTP to web documents directory

    If you control the system, you can implement SFTP by installing openssh-server. You can then use SSH for remote access as well.

    I've encountered this myself. I found that rebooting the router helped.
  12. [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.

    If you're considering systems other than PCs, IBM System/360 was perhaps the most important mainframe operating system.

    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...

    If there is software you need to run for work, and it does not run on Linux, that would seal the deal for me.

    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...

  21. 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.
