Samba, Linux SMB/CIFS client, Error 5 -- July 2023
--------------------------------------------------

You may find that trying to mount an old SMBv1 samba server (like a WDTV Live Hub media box)
from a Linux client, leads to an "Error 5".  Using smbclient or Fuse will both work, and yet
you can't mount it with the Linux kernel.  It's widely known you will need to use the "vers"
mount option, but it turns out that disabling DFS with the "nodfs" option is also needed.

So /etc/fstab will have an entry like:

Fedora, up to at least version 29 has incorrect Firewalld settings to allow
a tftp client to connect to a remote server.  The problem is that the
OUTPUT chain in the raw table of iptables is not configured to trigger
the conntrack tftp helper.  This raw OUTPUT chain is responsible for
connections created by local processes.

As a temporary fix you can add some config to the file:

   /etc/firewalld/direct.xml

A little feature to pass interactive comments to your favorite language
as-is. This lets you do one-liners easliy without having to quote
strings and semi-colons and other special characters.  Zsh completely
ignores interactive comments for itself, but passes them on to any
command with the leading hash character (#) stripped.

For instance you could do something like this at the Zsh prompt:

zsh> perl6 -e # my $a='hello'~chr(8+<2)~"world "~7*6; say $a if 0|1

loops

#!/bin/env perl6
use lib 'lib';
use Graphics::TinyTIFF;
use NativeCall;

# changed your library away from blob to this:
#
#   sub TinyTIFFReader_getSampleData( TinyTIFFReaderFile is rw, CArray[uint16] is rw, uint16 )
#
#  Didn't change anything else.  And then  this worked:

Subject: [PATCH] Ensure first terminal in a new session is displayed at
 creation

In a new session, the initial terminal may not be displayed
resulting in a grey screen.  If you then use the keyboard
shortcut to add a new terminal to the session, both it and
the initial terminal would become visible.
