Re: [PLUG] Ubuntu messed up LO!

[David Bridges]

I've always found the following helps with broken packages on a Debian
based system. 

apt-get -f install 

You can do man apt-get for more info.

Synaptic, Apt, or whatever all use dpkg under the covers.

Do 'dpkg --list' to see what is installed.

Make a list of things you want to remove, i.e. 'dpkg --list | grep
'somepattern' > files.txt

Then use 'dpkg deinstall' or 'dpkg -r' for each package you want to
remove,
you can gang them up on the command line if there are just a few.
There are various --force-[something] options if you run into trouble
with
dependencies or broken packages.

because that first '*' tells cron to repeat an action once every minute of the 
hour, and the second '*' tells it to repeat the action every hour of the day.

Pick an hour you want the message to appear, and replace 
* * 21 * *
with
0 {hour} 21 * *
and you'll get the message once, at the top of the hour, on the 21st of each 
month.

[PLUG] Linux laptop recommendations?

[David Fleck]

My ThinkPad E531 is showing signs of age and the effects of one too many 
beverages spilled onto the keyboard, and I am now seriously looking for a 
replacement laptop. Asking for any recommendations from the group for a 
replacement.

I use the laptop for web browsing and lightweight programming (generally 
command-line scripting), along with some video HDMI streaming and occasional 
DVD watching. The E531 has a built-in DVD-RW drive, which appears to be a 
vanishing feature in modern laptops. I can live without it, though - presumably 
I could find an external drive.

I'm somewhat partial to ThinkPads (I like the overall form factor and it's 
worked very well with OpenSUSE for me) but always interested in possible 
improvements. I'm intrigued by System76 and wonder if anybody has had 
experience with them (OpenSUSE or not), or any other model that they've found 
works well with Linux.

Thanks in advance for all responses--

how to write a small script to do the tftp uploads. The steps are
as follows
kp4djt@kp4djt64:~$ tftp 192.168.1.1
tftp> bin(set binary transfer)

Packet tracing on.(response)

At this point it will either start showing blocks being

I would like to write a script that just runs that, I would
have 2 versions one for devices which default to 192.168.1.1
and those who use .1.20, then it runs and all I have to do
is either edit it and put the upload file in or have it stop
and I paste/type the file name in and turn it loose.

Of course as soon as you invoke tftp it jumps into it's own
interface, I googled for writing scripts to control tftp, I saw
some that embed it in a bash script but appears that you
i have to make the tftp entries by hand with those scripts.

Anyone have any idea of how to write a script to invoke
tftp and insert commands to tftp?




I believe you want to explore the use of an "expect" script. This allows 
you to receive input from the system being connected to and acting when 
specific prompts are encountered.


It's been two decades since I have messed with this language, but I am 
certain that it will do what you want to accomplish, even if not a 
simple task to learn.

Re: [PLUG] Music Composing Software

I'd suggest Musescore (https://musescore.org/en) although at least for
me it is quite a learning curve.  

It would make things much more simple with a midi keyboard controller.
Any hardware midi suggestions would be appreciated.  I'm the cheap type

Re: [PLUG] filesystems question

[David Bridges]

I've forced this hundreds of times over the years working for a hosting
provider where we used software raid / LVM on almost all of our
servers.

I've found the following commands quite helpful when in the situation
like you describe.  I'd usually be using a CentOS rescue environment
mainly because I have it all set up to pxe boot, do installs, etc but
the Debian rescue environment works just fine too.

lvm vgscan
lvm vgchange -ay
lvm lvs

I'll always follow up with the following (assuming the commands worked)

e2fsck /dev/volumegroupname/logicalvolumename

<--snip-->

the array wasn't just in a degraded state when the new drive was added,
it could not be started at all. the system had crashed and would not
boot fully. it would load the kernel and whatever it could load from
md0, but once it came time to mount the volumes from md1, it stalled. I
had to go into a liveboot environment, manually assemble the array
(with --force), and add the new drive. it synced, then I had to re-
apply the correct name and uuid to the array. then it was detected and
started by the system on md0. but still could not mount the lvm
volumes.

Re: [PLUG] Replacement laptop

If you do decide to take a look at used equipment and you don't mind
buying out of state I think that https://discountelectronics.com/ is a
nice place to buy equipment from.  

I've bought lots of servers, workstations, and laptops from them over
the years.  If you are looking for refurbished Dell or HP stuff it
might be worth it for you to check them out.  They are based in Austin
and get new stuff almost daily.  Almost all systems come with a 1 year

I did separate searches for "python3-pcbasic" and "pcbasic" by entering
them in the search box at
https://www.debian.org/distrib/packages#search_packages to avoid 
possible sources.list related anomalies.

I just re-ran the search specifying "any" for suite.
"python3-pcbasic" is available in testing and unstable.

BTW it has a web site at http://robhagemans.github.io/pcbasic/ .

Subject: [PLUG] Debian buster newbie: recompiling libgd for freetype
support
Date: Fri, 4 Jun 2021 15:40:23 -0700

I'm attempting to add freetype support to libgd for debian
buster.  What's the best way to replace or add a recompiled
library in debian?  I can figure out the specifics, but I
do not yet understand "The Debian Way".



I've used the Scientific Linux variant of RedHat/CentOS
Long Term Support for many years, but now both are going
away.  All that is going away due to BHMR (Butt Headed
Management Reversals), so I am attempting a transition to
Debian Buster, rebuilding shell scripts, and recompiling
many C language point tools I've built over the decades.

I've built hundreds of "engineering animations" using libgd
to make png frames, then combined them into flash animations
and displayed those with firefox.  I labelled the animations
with truetype fonts. 

All that Just Worked, mostly because many in the Scientific
Linux community did the same things.  And now it Doesn't
Just Work.  The SL community is scattering to the winds ...
some to $$$ Enterprise, some to Alma Linux, some to Debian,
and a few (including some small engineering businesses 
disturbingly like mine) to involuntary shutdown.

SL supported international collaborations that perform big
experiments at the Large Hadron Collider and LIGO and on
ISS, so this may impact science productivity for years -
and my productivity for many months.



The good news is that I have learned how to make animated
PNGs with "apngasm", and that works better than SWF. 
That also simplifies the web pages in which I imbed the
animations, so this part of the transition is going well.  

But I'm tearing my hair out trying to understand and work
with all the variations of libgd.  The builtin fonts for
libgd look like 1980's video game crap.  I've added the
packages for truetype fonts, but libgd doesn't find them.

Stock debian buster libgd (2.2.5-5.2) complains "libgd
was not built with freetype font support" ... /if/ I add
the package that converts return codes into error strings.  
"bullseye" and "sid" use libgd 2.3.0-2 ... also not built
with freetype font support.  That version of libgd also
seems to be called libgd3, which is confusing.

It seems like the best way forwards is to recompile libgd
with freetype font support enabled, then replace the
system's libgd library ... but I don't know the right way
to do that, and my clumsy efforts could break other tools
and screw up updates and upgrades.

So ... how do Debian Cool Kids recompile and upgrade 
commonly used system libraries like libgd?

This sounds like a cable or hardware issue to me. If a drive is mounted 
and something happens and the kernel isn't involved, you will get a new 
mount address of the same thing.


Either the drives are going to sleep, as already suggested, or there is 
a glitch in the communication path which is causing a sporadic 
disconnect/reconnect sequence.


I have seen this periodically with USB, and TB3 likely uses something 
similar, where udev is involved.


Sorry that I don't have a solution, but if you have another TB3 cable 
you could use, that may help narrow things down if the problem goes away.

Re: [PLUG] Next topic: whiteboard software

[David Bridges]

I've only made simple presentations but here are 2 options.

Libreoffice can make presentations and was simple enough to do what I
wanted but can probably do much more.

I also use OnlyOffice from a nextcloud instance I have here at home. 
It works very nicely for Documents, Spreadsheets, and presentations. 
It's also very handy to have stuff available from the web or an
internal network.  The only bad thing about OnlyOffice is that you
cannot edit from a mobile device (requires a paid license).  The
collaboration tools available in OnlyOffice are also great as long as
all users are using a PC.

That makes sense.

However, sometimes people use various markup tools to generate text.
Most

So I was hoping for a list of options

I don't use it, but the utility ingests mail, analyzes it, and then

There shouldn't be any reason why you might be able to trigger a script

Re: [PLUG] GUI app to access files on another Linux computer

[David Bridges]

As long as you have ssh access between the computers a decent file
manager should work nicely for this task.  I know that NFS was
mentioned in the original post but I like simple solutions.

In the file manage on Gnome I can set a location I want to access using
a syntax along the lines of

sftp://kdb16@lfs17/home/kdb16

I use ssh key authentication between my computers and have quite a few
bookmarks set up to automatically browse many computers both local and
remote.

I'm assuming that whatever file manager you use would have this
functionality in 2021 but ymmv

I tried it. It was already installed. I tried sshfs and got
'need to specify destination,' so I specified the ip address of the
other computer, which gave me 'address must be in brackets' (why?) so i
added the brackets, and the error message was just repeated.

I'm not impressed with sshfs.

Re: [PLUG] Auto start HTOP in tty.

[David Bridges]

The very first hit for me when searching for the terms below on
duckduckgo more than likely has the information you need since it has
information for Ubuntu and also information for systems using init or
systemd.

start htop on tty on boot 

As with most things there are more than one way to do this.

I think you want to look at /etc/inittab for that configuration.

It may be helpful to look at how X is (re)spawned on your system and see

The space did actually get allocated but only to ubuntu-vg (the volume
group)

The logical volume (ubuntu--vg-ubuntu--lv) was only allocated a small
portion of the space.

gparted, well any partitioning tool is not what you need here, you just
need to extend the logical volume and then resize the file system.  

Resizing the logical volume and resizing the file system can be done
while the file system is mounted.  The commands below are examples of
how you can do this.

lvextend -l +2332415 /dev/mapper/ubuntu--vg-ubuntu--lv 

The command above will use up the rest of the free PE's (physical
extents)  Instead of using the -l you can use -L and specify a specific
amount of disk space instead of the number of extents to extend the
logical volume by.

man lvextend is your friend.


Once the logical volume has been extended you can then resize the file
system using the following command.

resize2fs -F -f /dev/mapper/ubuntu--vg-ubuntu--lv

The command above assumes an ext2/ext3/ext4 file system.  If your file
system is something else you would need to use the appropriate commands
to resize it.

man resize2fs is also your friend.

A quick search for debian installer disable recommends provided your
answer to me in the third hit.  ;)  

Well not the complete answer but if one knows how to pass boot
parameters when booting the install media you can easily accomplish
what it seems you want to do.

FWIW the link is to the boot parameters section of the Buster
installation guide so reading the Debian documentation could have
provided the same answer. 

To disable installing recommended applications you can do the
following.

Boot install media
Press the escape key
at the boot: prompt type the following
expert base-installer/install-recommends=false

I tried and and unselected everything in the package selection screen
except for standard system utilities.  The install completed without
installing recommended applications and also set APT::Install-
Recommends "false"; in the new system.

If it still installs more than what you want good luck on your quest.

Re: [PLUG] A minimalist oriented Debian derivative?

[David Bridges]

There is a difference between the installer and installing packages on
an installed system.

It looks like you can change the behavior.  Checking the apt
configuration on a fairly new install of mine I see that recommended
packages is enabled.

root@jekyll:~# apt-config dump | grep Recommends
APT::Install-Recommends "1";

It looks like you can override that behavior but creating a new file
in /etc/apt/apt.conf.d with something like the following.

APT::Install-Recommends "0";

Might help, might not.

Re: [PLUG] A minimalist oriented Debian derivative?

[David Bridges]

Not a derivative suggestion but maybe this will help.

When you start the installer if you choose the Expert installation (I
believe under advanced section) or if you press the Escape key and type
expert at the boot prompt you can get a very minimal system installed
although there will be a few more questions that you have to answer
along the way.

The trick is when you get to the package selection screen to uncheck
everything except for Standard System which will give you only a basic
system with no gui.

Re: [PLUG] How to use linux for those who need to learn

[David Bridges]

Sorry for the novel.  I know I'm not really providing an answer for the
document/book you are looking for but I thought I would share a recent
experience I had.  

As technical users I think that we tend to think to much about what we
think a computer user needs to know.

> Looking for an end user document/book that's distribution agnostic.
> Focused
> on basics, such as how to view a PDF file.

Does the user really want to learn about a computer or
applications?  Computers for most people are just a tool to get work
done and my opinion is that there should not be a big learning curve to
do normal every day tasks.

Earlier this year a friend of mine who works with insurance benefits
for a major university had his laptop die the first night we were all
out of town for a tennis tournament.  He said he didn't like using a
computer in the office centers of the hotels so I let him borrow mine
since my wife also had hers that I could use for my work.  I use Debian
along with the Gnome desktop environment.  He is a smart guy in what he
does but is not even close to being a technical guy.  

> Based on the above, any modern user-friendliness distro this user is

The only change I  made to the account I made for him was to enable the
Applications extension so that there would be an application menu.  He
had never used linux and I told him to give me a call if he had any
problems.  He never contacted me needing help.  The morning at
breakfast thanked me for lending him the computer and asked if he could
keep it until Sunday.

We had lunch with our friends before we all headed back home on Sunday
and I asked him if he was able to get his work done with my laptop.  He
said that it sure looked different but that he found firefox and that
along with the Writer application he found in the menu was really all
he needed to get work done.  He said at first he missed the task bar
but that with Alt+Tab was able to get back to his programs and was a
bit proud when he discovered that the Windows key would show all of the
applications and allowed him to click on the one that he wanted.  

I asked if he found anything that would not work and he said he had no
problems at all.  He said that other than work he did some youtube
stuff, browsed the web, and that he and found some nice games to relax
with.

If a user is really concerned about not having Windows installing these
type of distributions might be a big help but from my experience owning
a computer business people tend to complain a lot about computers not
working like they expect them to.

In linux there are more things to learn than any of us will ever have
time to learn but not everybody is a linux person like we are.  Not to
start a distro/desktop environment war but I think that providing a
nice modern desktop (gnome/kde) on a distribution that doesn't require
you to look for new applications beyond something like the software
apps in Debian/Ubuntu/Mint would be much better than setting up a
distribution with your favorite window manager.  If it doesn't work for
them or they want more or want to learn more things you can always show
them different things.  I know you like Slackware and XFCE and I was a
Slackware user for a long time but it can be a lot of work.  I think
XFCE is nice as well but I do not see it as a good environment for a
complete novice.

I have a few family members that I have set up with Debian stable who
are very happy.  I have used Debian for decades and have their systems
get automatic updates because I've never really had any issues when
following the stable branch.  I hardly ever get support calls from them
and when I do it is usually simple things that aren't really a problem.

Re: [PLUG] When is a VPN advantageous?

[David Bridges]

I use a VPN on my laptop when I am away from my home, well actually the
laptop is even configured to use the VPN even when at home and the
laptop is using our wireless.  It's very handy and allows me to route
everything through my home network which I consider secure.

I do not use a paid solution I use openvpn that I have set up on a
server at my house.  The authentication is handled using certificates
combined with passwords.  I do not run any GUI apps over the connection
but have my email client configured to connect to a private email
server on my lan, my private git server, ssh.  Once connected to the
VPN my DNS servers are also set to use a personal bind server that is
on my private network.

Early on I did run into some issues at some hotels that used the same
private network that I use a home but with some routing configuration
in the VPN client the problem was easily fixed.  If you use tools/apps
that do things based on your location they will not work as expected
because the location will always be where your VPN is but this doesn't
bother me because I tend to block that stuff as much as possible
anyway. 

This has worked very well for me for years and was well worth the small
amount of time that it took to get it configured.  I also have a VPN
set up on a work machine just in case my home connection is down.  This
doesn't allow me to use the resources on my home network but it allows
me to route things securely through a server that I have total control
over which should never be down.

To refine my answer, your output above indicates that it is attempting 
to open the file named "log" in the root ("/") directory, and that 
probably doesn't exist, and it likely wouldn't have the permissions 
required if it did.


I stand by the suggestion to configure the PMDIR value above the LOGFILE

Two different responses here.

First, the error appears to be trying to write to the directory "/log" 
which it will never be able to do. I would suggest checking the 
configuration to make sure that a real file name is specified.


Second, the mode of 666 is considered insecure because it permits the 
world to read and write to the file. Mode of 600 allows only the owner 
of the file to read and write.


Being that this is likely a private, single-user system, this probably 
isn't a huge security risk, but only you can answer that.

How are you configuring the mount for this? In order to use Nautilus or

I do something similar with autofs in my home network, and it works

In an earlier reply I mentioned using a file to exclude things that is
referenced on the rsync command line.  I know that things can be
excluded as an argument on the command line but I've been tripped up
doing it like that in the past.  I would suggest trying the following 
using your correct information of course.

Create a file on the source node /home/rshepard/excludes.txt that
includes the directory you want to exclude (in this case data no /
needed), and possibly excludes.txt

The following should do what you want as it works prefectly for me with
my specific directories and excludes.

rsync -arvP -e ssh --exclude-from='/home/rshepard/excludes.txt'
/home/rshepard/ rshepard@salmo:/home/rshepard/ 

I have files with commands resembling the one above on several
computers which have worked for me for years.

Hope this helps

Re: [PLUG] Open Source Help Desk software

[David Bridges]

We have quite a few customers who use osticket https://osticket.com
which is open source and can be downloaded and installed on your
server.  It seems to work quite well and is fairly simple to set up.

They also have hosted versions but that doesn't sound like what you are

[PLUG] Distro suggestions

[David Fleck]

For reasons not necessary to go into here, this long-time FreeBSD/OpenSUSE user 
needs to move to a new laptop* Linux distribution, and I have the following 
choices:
CentOS
Fedora
Mint
Ubuntu

I use CentOS in a text console / server at work, and it seems okay; I'm not 
familiar with the others at all. I seem to remember Ubuntu being described as 
more Windows-y than most distros, which I don't care for. But I'd like 
suggestions as to the pros/cons of the four listed above as laptop OS'es 
specifically.

Re: [PLUG] Grub 0.97: convert VM with two disk to VM with single bootable disk

[David Bridges]

There are many variables and unknowns related to what you want to do
depending on how the original VM was built and installed.  I have used
the guidelines below to do the same sort of things you are wanting to
do.

Modify the /etc/fstab entries so that they point to the correct new
locations.  Some locations probably use labels (LABEL=/boot etc) and
from what I gather from your email you are no longer using LVM and are
only using 1 partition.  If this is correct you would need to comment
out old the entry that point to /home and modify the line for / so that
it points to the correct device (/dev/vdy1).  You didn't mention what
you are doing about swap so that is an exercise left up to you.

Shutdown the VM and connect a CentOS 6 CD to it and boot it using the
CD and enter rescue mode.  You'll be asked a few questions to get
things started.  When prompted to scan for existing installations
yes/ok.  If you have things copied over and have corrected the fstab
file it should find the install and mount it all under /mnt/sysimage. 
If the install was found and mounted you should be able to install grub
using the following.

At the shell prompt type the following
chroot /mnt/sysimage
grub-install --no-floppy --recheck /dev/vdy

If the grub-install command is successful type exit to leave the chroot
and exit 1 more time to reboot.  In theory the VM should be able to
successfully boot using the new image file but there could be some
issues depending on how things got copied from the old system.

In cases similar to what you have I usually just spin up a new VM make
a copy of the /etc directory on the new system to /etc.old then use
rsync to copy everything from the old VM excluding things like /proc,
/sys, /dev, /var/log, and /boot (unless you really need something in
it).  Once the rsync completes I restore the /etc/fstab file and things
like the /etc/sysconfig/network-scripts/ifcfg* files from the /etc.old
directory.  If you did rsync /boot you should probably run the same
sort of grub-install command listed above before rebooting.  This
usually works like a charm for any distribution as long as you know
what crucial files that need to be restored.

Good luck

I've used Bacula for backups/restores for many years both Linux and
Windows and it has worked great for us.  I do see that there is a
client bacula-fd for Mac as well but I do not have any experience using
it.

There are some GUI frontends for it but we have always just used the
command line.

It can make bare metal restores although I only have done this on linux
systems and it does take some additional work, in my case custom boot
images we boot via PXE that contains a preconfigured bacula-fd client. 

I use it for a handful of Windows servers and a little over 100 linux
servers at work and have it running at home for all of my personal
stuff (linux only)

If you open a new spreadsheet and set all of the fonts/sizes to what
you want them to be you can then save it as a template and set it to
the default so that new sheets you create will have your settings
preset.

New spreadsheet
Make changes you want
File --> Templates --> Save as Template
Set the name, select My Templates as the category
Click the Set as default template
Click the Save button

Next time you open libreoffice calc it will use your settings.

Not sure about the help on my system (Debian Sid) the help is displayed
in my default web browser so you can just use ctrl + to increase the
font size as needed.

Actually it is quite simple to set fonts and column width for the
entire spreadsheet in Libreoffice Calc or pretty much any modern
spreadsheet application.

Selec the entire sheet by clicking the square in the top left of the
sheet between column A and Row 1.

Choose the font you want and it will be applied to all cells.

Right click on a column and then select Column Width then set the width
you want and make sure that a check is in the checkbox beside Default
Value.

Re: [PLUG] question on linux tool to clean URLs

[David Barr]

Hey, Randall,

To be pedantic, the tracking tags and such are all stuff that appear
after the question mark delimiting character in the HTTP PUT request,
right? `https://foo/bar/baz?evil_tag=evil`

The trick then, is to select only the lines containing question marks,
and then delete from the question mark to the end of the line. Try this:

```
sed -e '/\?/ s/\?.*$//' 
```

Pedantry again: That's "select lines containing a (backslash escaped)
question mark," followed by "substitute all characters from and
including that (backslash escaped) question mark to the end of the line
($) with nothing."

I haven't tested this on a file, so I deserve whatever mockery I get if
I missed something.

Cheers!

Let's start with the basics then.

If you get back a blank line, something is preventing the variable from

[PLUG] Local network routing mystery

[David Fleck]

My wife and I have 2 practically identical ThinkPad laptops, both running 
OpenSUSE 42.3.  They connect to a wireless router via DHCP.  We also have 
several desktop machines (Linux & FreeBSD) with static IP addresses. All the 
machines are connected by a router.  Both laptops can see the router, the 
outside world, and each other.  But one laptop can see all the desktops, and 
the other one can't see any of them. The desktops can't see the one laptop, 
either.

As far as I can see, the routing tables are the same on both laptops:
m2:~ #  route  ### This is the non-connecting laptop
Kernel IP routing table
Destination Gateway Genmask Flags Metric RefUse Iface
default 192.168.1.1 0.0.0.0 UG60000 wlan0
192.168.1.0 *   255.255.255.0   U 60000 wlan0

dcf:~> route   ### This is the connecting laptop
Kernel IP routing table
Destination Gateway Genmask Flags Metric RefUse Iface
default 192.168.1.1 0.0.0.0 UG60000 wlan0
192.168.1.0 *   255.255.255.0   U 60000 wlan0

But when I try to ping from the non-connecting laptop:
m2:~ # ping 192.168.1.9
PING 192.168.1.9 (192.168.1.9) 56(84) bytes of data.
^C
--- 192.168.1.9 ping statistics ---
5 packets transmitted, 0 received, 100% packet loss, time 3999ms

whereas:
dcf:~> ping 192.168.1.9
PING 192.168.1.9 (192.168.1.9) 56(84) bytes of data.
64 bytes from 192.168.1.9: icmp_seq=1 ttl=64 time=9.59 ms
64 bytes from 192.168.1.9: icmp_seq=2 ttl=64 time=0.960 ms
64 bytes from 192.168.1.9: icmp_seq=3 ttl=64 time=0.960 ms

I'm flummoxed. Everything I can think to look at on the non-connecting laptop 
looks right, but the machines simply don't 'see' each other, even though they 
can see other machines on the network and there is no difference in network 
topology distinguishing connecting and non-connecting machines. Reboots (of 
desktops and the laptop) haven't helped.

Last data point: this was all working correctly 24 hours ago.

Is it possible that your old system overwrote the keys from old system

have the same happen again after this run completes.

   However, when I try to copy the /opt partition from salmo to baetis I 
get

a permission denied (publickey) error. Running 'ssh -vv salmo' from the new
desktop shows sending and receiving packets with no issues until this:

Permission denied (publickey).

   Line 5 looks to be trying to send the private key rather than the public
key.

   Here's what I checked:

   1. Perms for both hosts' .ssh/ are 644 except for the private keys for
 which it is 600.
   2. Both hosts have the other host's public key in 
~/.ssh/authorized_keys.

   3. Both hosts have the other host recognized in ~/.ssh/known_hosts.
   4. From salmo I can successfully connect to baetis,

   Since rsync worked on baetis yesterday to copy my home directory from
salmo I'm not seeing why today it will not copy /opt. And web searches
(almost all from ubuntu and github users) offered nothing different from
what I checked.

   A clue stick will help.



A series of thoughts, but nothing specifically to help, sorry.

Are you able to connect to salmo using the password, and is it 
configured to accept the ED25519 key format?


Are both machines set up with the UID/GID values for the username in 
question? You can try specifying the username on the rsync call to be a 
bit more specific, too. (I don't expect this to be a problem, but worth 
looking at.)


Also, even if /opt is set for 777, directories below that may not be, 
and that may be a cascading problem after the key issue is resolved.

Not exactly what you want, but you can specify file system type with 
-fstype xxx.  Anything in /proc is fstype 'proc',  so maybe you could
specify "! -fstype proc" as one of your sets of arguments to find.

Re: [PLUG] Distinguishing instances of GUI file manager by color

You might look into the Meld application.  It is file/directory compare

via apt-get on Debian.

[PLUG] Semi-OT: Anybody here used Bazel?

[David Fleck]

I've been tasked with evaluating the replacement of build tools for a
very large, multi-platform, multi-language (mostly Java and C++) 
client-server application.  Currently, the app is built using a
combination of Ant, Ivy, Java, Make, GCC, Visual Studio, and a whole
lot (and I do mean *a lot*) of Perl gluing things together.  It's
complex, brittle, and slow.

Bazel (https://bazel.build) sounds like it might be a candidate for us,
as it is designed for big heterogeneous applications like ours. But I
don't find a whole lot of information about it other than its own web
page, and I find its tutorials rather opaque and unilluminating. 
Curious if anyone has had experience with it, especially for C++
builds.

[PLUG] Roll-your-own VPN server?

[David Barr]

Good Morning,

If I were to build a VPN server for transient client connections, like mobile 
devices or laptops, what would you recommend?

- Bonus points for using certificates for the server ~and clients~, so devices 
would have to be "registered" in advance.
- Bonus points for requiring 2FA on top of that, to reduce the risk of a 
lost/stolen device.

I haven't looked in a while, but I recall OpenVPN was really oriented towards 
setting up permanent connections, and configuring for transient connections was 
really convoluted.

Thanks!
David

david,

   Good question. Can it find a difference in a specific field and change
only one of them? Perhaps, but I've no idea.


Without a bigger sample size of data from you, I'm not sure.

I use the uniq command a lot when I pull a list of stuff (usually IPs 
and more) with grep or other utilities from log files and then pipe 
things through uniq to get a count of times an entry is found (-c flag).


Provided all data lines are unique, except for your one duplicate line, 
then yes, you could use this. A crude, but effective approach to test 
would be:


cat $file | uniq -u > $outfile

There are a lot of approaches, and I like the awk approach. This might 
just be another tool for you to use in the future to satisfy other needs.

From Richard's link:

Activities were introduced with the KDE 4 release series. For some
reason, they have never caught on, partly because the project has
rarely emphasized or explained them, and partly because how they are
different from virtual workspaces has never been clear. It doesn't
help, either, that from the virtual workspace pager on the panel, you
can set virtual workspaces so that each can have its own icons, widgets
and settings, just as Activities can.

I've been using KDE + SuSE for over a decade, and I *still* haven't figured out 
what "Activities" are or why I need them. On the other hand, I've found that I 
can ignore their existence without detriment.

(I'd just like to take this opportunity to give a shout-out to whomever put 
together the OpenSuSE 42.2 -> 42.3 update process. Smoothest upgrade I've ever 
done, on any OS.)

Perhaps basic256 is close to what you are looking for.  It is packaged
for Debian so it should be easy enough to check out.

apt-cache show basic256

Some people have reported that bill...@spiritone.com works, at least
some of the time.  If you use Facebook, you may want to check out https
://www.facebook.com/groups/1616813681672836/, the "Aracnet & SpiritOne
Refugees" Facebook group. You will find many fellow sufferers there,
and possibly some useful information.

Personally, we were billed monthly and in early Oct. I gave up on
trying to contact SO, called up the credit card co. and told them I
disputed the Oct. monthly charge, and any charges from then on. That
seems to have worked for us. I'm not sure how that will apply to your
situation, though.

Good luck-

The password should be salted in this file even if it is password!

Is there a simple way to use an smbpasswd file properly salted 
without implementing a full samba server?


The proper tool that I know of is "smbpasswd" as an executable, which
is part of the samba-common-bin package on my system (Debian).

It may have dependencies which includes a full smb server (which I
run), so this may not be helpful information.

I am most concerned about the password having to be in plaintext when 
transmitted over the network.  Even if
there is a way without a full samba server deployment to have the 
password sent in encrypted form over the
network, that would be great.  The server is probably the latest 
incarnation of Windows server.  I don't

like the idea of having to have a Linux user for every Windows user either.




Sure, I get that, and agree with the concerns. I was looking at the 
smbpasswd man page initially and this is why I think you want to use 
this utility:


  "On a UNIX machine the encrypted SMB
   passwords are usually stored in the smbpasswd(5) file."

Now, the problem with the utility is that unless you do something fancy, 
you may have to be on the localhost where the share is exported to set / 
reset the password as a user. This may not be feasible in your situation 
unless there is a web interface that you can front smbpasswd with to 
allow users to change passwords.


When mounting a share in a Windows VM on my Linux host, I have to auth 
with a pop-up window of user / pass to access the shared directory. I'm 
not sure if (and don't believe that) you have to have a Linux account 
for the Windows user. They are different password files, but my 
experience is also limited to a full samba server, so your needs may be 
more an issue than mine.

This is more of an ol' skool mentality that reflects a serious lack of a

In reality, we should actually see less and less of this over time as 
the ICMP protocol suite is very useful and blocking it doesn't amount to

Coming from an admin background, you are correct that I don't have a

my mistakes, the input of others, and from readings that I can pick up.


I agree that ICMP is a useful too, and I am frustrated by the security 
group at $WORK that has disabled the return of these packets.



Other tools that you can try are telnet to the port for the service in
question, nmap to check for all open ports (potential for looking like an
attacker), and netcat (nc) to test for specific, or scan for all open,
ports.

A deeper way to search if things are connecting at all is the use of
netstat, Wireshark, or tcpdump in some cases.


I've been a network engineer for over a decade and I've learned to use 
the simplest tool possible for a task. In this case tcping is a very 
good simple and easy to use tool for anyone who's just wanting to test 
connectivity to network host. Most implementations allow for a port 
number to  be specified. If you're unsure of the port number from the 
Linux cli you can cat the /etc/services file to get a listing of udp & 
tcp ports w. description that's updated by IANA.


e.g.
~$ cat /etc/services
# Network services, Internet style
#
# Note that it is presently the policy of IANA to assign a single 
well-known port number for both TCP and UDP; hence, officially ports 
have two entries

# even if the protocol doesn't support UDP operations.
#
# Updated from http://www.iana.org/assignments/port-numbers and other 
sources like http://www.freebsd.org/cgi/cvsweb.cgi/src/etc/services .
# New ports will be added on request if they have been officially 
assigned by IANA and used in the real-world or are needed by a debian 
package.

# If you need a huge list of used numbers please install the nmap package.

tcpmux        1/tcp                # TCP port service multiplexer
echo        7/tcp
echo        7/udp
discard        9/tcp        sink null
discard        9/udp        sink null
systat        11/tcp        users

This particular implementation, 
https://www.elifulkerson.com/projects/tcping.php , provides a lot of 
HTTP mode options as well setting wait interval for a response, 
calculating jitter (variance in delay) and prefer ipv4 or ipv6.


Cool, a new tool to check out. Thank you for this information.

Network connectivity is going to likely become more problematic, and 
our means of testing things will likely become more restricted as time 
passes.

Just my guess, but it's a trend I have been noticing.


I don't follow nor subscribe to this logic at all. I expect network 
connectivity and ways to test to it to only get better as everyone and 
their grandparents demand well performing, highly reliable internet 
connectivity from all of their devices, everywhere. 5 years ago while 
working at an ISP in downtown Portland I had to work on networking 
problems from end-users of our ISP business partners who where 
complaining about high ping times in their favorite online game. And I'm 
talking about sub 150 ms round-trip ping times which is used as the 
measuring stick for toll quality VoIP.


My pessimism revolves around the increasing number of attacks by black 
hats (thinking of Mirai), human errors that impact large networks 
(recent Level 3 / Comcast routing issues), and the potential of the 
federal government trying to take away a level playing field.


It is my hope that the tools will get better and with it the willingness 
on the part of the major ISP players to provide more transparency and 
information real time as problems happen in the future.

All good things for me to learn from and consider. IPv6 is not something 
that I have deep understanding of, and maybe now is the time to start 
looking at, and learning, it again.

Something I've thought about for when I have my domain host back under my

back. I haven't seen much documentation out there about a mail server that just 
spools messages until the primary MX is back on line, though.
