    That's what you want: as the address is in the 127.0.0.0 network,

    require your LAN to be set up, and AIUI it's like localhost
    (127.0.0.1) in that it doesn't touch the network hardware.
    Indeed, the entirety of 127.0.0.0/8 is the virtual loopback adapter
    (i.e. "localhost").
    Doubtless yet another fallacious notion, but I thought IPV6 opened up
    the flood gates of assigning "real" ip addresses to whatever the heck
    Gene's talking about.

    I guess it isn't happening any time soon.
    The more rural WV areas are an ipv6 desert, and given Debian's penchant for >> ipv6, its disabled here.  I've no clue, but it seems to me that if it gets >> no replies trying ipv6, it should fall back to ipv4.
    The problem is what is "it". Currently it's each application (using some underlying library). The normal path is:

    - resolve the name (there you can get both A and AAAA records, if
    the programmers know what they are doing)
    - try one of them: which one first? Wait for some timeout (how
    long?) try next.
    - ideally, try all of them in parallel (suddenly you end up with
    an application written in non-blocking style or -GAH!- even
    some multi-threaded monster.

    The solution is underway, is called "happy eyeballs" [1] and will be
    here some day.

    At the DNS resolution level you can prioritise whatever suits you by
    editing /etc/gai.conf, which comes with a man page.

    Which in my case, never heard about before, was there but 100% commented
    out. Uncommented what claimed be ipv4 preference but it didn't do
    anything for my freezes.

    Thank you Tomas.


    Cheers

    This happens only in that directory and only when you own the file?

    I think its a bit more complex than that. I'm the only user since I'm
    alone now, but it does not seem to bother synaptic if I launch it from
    the gui menu or sudo apt to update. Working as me 99% of the time, its a PITA.  I keep the stuff I use current, like the weekly builds of
    OpenSCAD so there's quite a few AppImages.  So my $PATH has been
    expanded to include that directory and a /home/me/bin where I keep my
    bash scripts.

    Thanks John.
