Re: [PLUG] Cannot open config file

[Larry Brigman]

Where is the default.conf file located?  Is dirvish running as something
other than root?
Unless the directory has execute permissions on it, only root can read
anything in the directory there
by making the config file unreadable.
I've had upgraded packages change how things run like changing the running
user of the processes.

Take light rail to downtown Hillsboro (3rd street station?)  to find a few

Sports Look is right at the stop.  Other places are only a couple of blocks
away.

Re: [PLUG] trying to lock down DNS addresses problem

[Larry Brigman]

You can install your own wifi router behind the cable modem.  At that point
you could change the settings that the router hands out for DNS.

The pi-hole project shows how to change the settings where they point to
your local pi-hole server and it forwards anything unknown to a location of
your choice.

Re: [PLUG] trying to lock down DNS addresses problem

[Larry Brigman]

You can load up the bind-utils package.
That gives you the command dig which allows you to explore the DNS
information more than
you can with just ping and a browser.

You can use dig on the address but be aware that not all IP addresses have
a reverse lookup.

I had issues with kvm too.
I finally gave up.

A program called "Synergy" from symless.com

There is(was) an open source version for a while and it worked for me.

Re: [PLUG] Logging network use while using Zoom

Zoom uses an adaptive bitrate codec.  The bandwidth you use will be
dependent upon latency to and from the server.
A test on your broadband connection will be different than a wireless

Re: [PLUG] Internet providers

[Larry Brigman]

My experience with Ziply has been pretty good.  I ordered an upgrade to 1Gig.
They waved the installation fee.
The installer had to do a rewire of my twisted pair from the Fiber
termination to my router.
My setup was just two pairs (I started on DSL at this location).
Gigabit Ethernet requires all four pairs.
The installer took almost 3 hours and need to replace the ODN.

The installer checked the bandwidth and that is how we found the issue.
Afterward, I found that using Chrome will limit bandwidth to a tab.
Checking from Linux with a speed test app (non-browser-based) got me
930Mbps (Max theoretical is 970Mbps.)
Did the same on my Windows box and got close to that.

I'm using my own router.  It wasn't an issue with them.

Re: [PLUG] Raving mad RAID

[Larry Brigman]

You can use mdadm to examine the superblock on each drive and it will
give you the details of the array that the drive thinks it is in.
Without a mdadm.conf, the kernel will attempt to assemble the array
based on what it finds in the drive superblocks and will default to
md127 and count up from there.
/proc/mdadm will give you the status of the assembled arrays directly
without the need to go through the mdadm util.

Re: [PLUG] Creating array with mdadm

[Larry Brigman]

There are tons of options for mdadm.
No, you should not put a format on the devices prior to adding them to
the array.
It is recommended that you partition the drives prior to adding them
to the array but you don't need to do that.
You can just use the raw drive.

Re: [PLUG] Stress-testing a hard disk

[Larry Brigman]

In my former life as a test engineer for a disk company, we used custom
testers to stress-test.
That eventually moved to custom code loaded directly on the device to do
the work.
When I moved to Linux we used direct-io libraries to write and read/verify
random or patterned data to the drive; in both seq, random and butterfly.
Low-level tools like the sg3-utils have a large set of direct disk access
tools.
Other tools to use are IOZone and FIO to run a large sample of tests over
and over again.

Re: [PLUG] Search entire filesystem except two mounted partitions

[Larry Brigman]

If you were looking for mounts why not use this?
cat /proc/mounts

you would probably need to filter it some to get what you want as it
contains every mount.

Re: [PLUG] Your first PLUG talk!

[Larry Brigman]

I have a talk (or two) in mind but I will need some help getting it worked
into shape.
Maybe if I feel good about it, I might submit it to OSCON but I think that
is a stretch.
I have given one of the Advanced topics long ago on disk drives and
S.M.A.R.T which is embedded in all drives these days.

Re: [PLUG] How do I get ssh to not challenge for a password

[Larry Brigman]

The only time I had something like that happen was when the user's file
system wasn't properly labeled for SElinux.
sshd from the command line doesn't source or use
/lib/systemd/system/sshd.service nor /etc/sysconfig/sshd
You can also use -vvv from the client side to see what it doesn't like.

Re: [PLUG] ssh -X "Could not parse arguments: Cannot open display:"

[Larry Brigman]

Maybe I'm stating the obvious. Normally you would be running this command
from a local X client where the shell would have the $DISPLAY value set.
Like this:
echo $DISPLAY
127.0.0.1:0.0

Once I connect via ssh -X,  the same command produces this output:
echo $DISPLAY
localhost:10.0

You have three options in the destination host sshd_config that control
whether you can have the application display on the remote server.
X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes

Only the first one needs to be set.  The other settings are default and
don't need to be changed.

Maybe another obvious fact
Restarting sshd will allow it to operate with changed settings on new
connections.  Existing connections will continue with the old settings.

Re: [PLUG] rsync in a cron job

Even the shell in cron could be different from your login shell.  Only the
location running cron should be affected.
The ~/ is a shell alias pointing to the $HOME variable.

Re: [PLUG] An apology needed? - was [Re: Wanted: handheld data collection device with Linux OS]

[Larry Brigman]

No offense taken.

I have worked as a test engineer in multiple areas and as a software
engineer including doing some embedded development.
I typically get requirements for the task to be accomplished and some idea
of budget.

With that information I craft a design or select hardware for a
hardware/software solution.

>From my projects, I have always needed to have some level of connectivity.

For remote field collection of data,  I would still want external
connectivity such that the data collected wout automatically transfer when
connected to the network.

For long term collection; internet of things or custom solutions use mesh
networks with points of upload via cell networks or satellite.

Data collection is more about the data than how it is collected or on what
OS platform.  The bigger issue would be making sure the  data is
transferable and in a readability format.

The list tries to assist with your request and requirements.  When we
cannot find exactly what is required, we pose possible alternatives.  Not
knowing the underlying requirements sometimes gets you responses that go
far a field.

Re: [PLUG] Wanted: handheld data collection device with Linux OS

[Larry Brigman]

I think these requirements are about 20+ years too late.  Even when there
were PDA devices to they didn't have standard USB connections as the
connector was too large.

The retail market is Android or iPhone these days.
To get something close you would probably need to start searching in the
industrial area.  Those devices will be very expensive.

20+ years ago, I set up a data collection system.  It used a handheld
terminal with a hardwired serial connection.
The system was driven from screens via database coding.

Adding custom software to any device should be the norm even for Windows
devices.  You would just need to learn the SDK to write it yourself.

Devices with cell phone communication are required to have an Airplane mode
to turn the radio off.

I would add checking of the return code (exit code) for the 'cd' commands.
As it is now those could fail but something latter would have to detect the

Do you have more than one home directories?   I would think that should be

It's common to have a $HOME/bin directory to store scripts and add that
directory to the PATH.

Re: [PLUG] [OT ? ?? ???] Linux and computer literacy

The local 169.254 address is part of zeroconf.  If that package (avahi on
some distros) isn't loaded or the service is disabled/not running then
there won't be any autoconfiguration.
I did see that one of the interfaces was up with link(UP,LOWER_UP) in the
output.

Re: [PLUG] How to confirm my router is safe

The second piece that I saw was to turn off upnp protocol.
Akamai(sp?) has a white paper about it and a list affected routers.

Do some searching.  Most of the hba controllers can replace the firmware

Re: [PLUG] CentOS 6 to 7 migration

[Larry Brigman]

The biggest learning curve is systemd.
If you have service scripts for things, you will need to convert them.
Also file system defaults to xfs.
NFS also goes to the next version.

Re: [PLUG] [OT?] Internet privacy? ?? ???

[Larry Brigman]

Clicking on a link in a YouTube video could get that type of information to
a source that could/would use it,
as the link could take you off the youtube site completely.
Any site that he connects can collect any information that the browser has
configured as to his identity.

Also without any clicking, he could receive spam email that looks like it
was extracted related to his viewing habits
but be totally unrelated.

Re: [PLUG] Am I asking the "right question"

[Larry Brigman]

'chroot' is an isolation/security mechanism.  It doesn't allow programs
running within it to access anything except the kernel and the
programs/libraries within the chroot.
For what you are doing, think of it as a file system tree that you can test
most of your boot environment (short of booting) prior to needing to
actually boot it.
And because it is just a command away,  it is fast to change and experiment.

Re: [PLUG] Figure out IP camera

[Larry Brigman]

Unless this is a multi-thousand dollar device, I suspect that it isn't
doing anything fancy except maybe encryption but that could prevent them
from exporting the device.  For port 53, you will need to point dig at it.

For VLC, the it to open a UDP stream at the ports in question.

Re: [PLUG] Figure out IP camera

[Larry Brigman]

Have you tried VLC against one of of the ports?
Also port 53 is normally DNS. Maybe it will provide the necessary
information.

Folks,
I purchased a borescope, it has a wifi output on it to view the borescope
video,
but it works with android and iOS. I am trying to get into it with a web
browser to
see if I can pull the video that way.

A scan shows the following UDP ports open
53
8000
49153

I am assuming that they are using one of those ports for the video, but not
sure how to try to get it to send video to me without the app. I have tried
to
get a packet capture on the android device I have the app installed on.

This is a General Tool borescope (same concept at an endoscope) I would
like to be able to view the video on something beside a phone. I have been
able to find the paths to video sources on ip cameras but this thing has me
stumped.

I tried running wireshark on a laptop and tried to do a capture on the data
on the Wifi channel but no joy. I remember that I used to be able to do it
in
the past, but guess either the encryption or something is not working in
promiscuous mode. .
