One thing you could do is have a dedicated machine that you just use
for accessing your financial institution. On that machine you would
just have Chrome and nothing else and you would not use that browser
for anything else.

Brave is based on chromium as is Chrome so I don't know exactly what you
are avoiding by using Brave instead of Chrome. Both Firefox and Chrome are
really good browsers. Each have their strong and weak points.

Re: [PLUG] RIP JJJ

I remember John arriving at his first Plug meeting many years ago. I
was a bit early for the meeting and he wandered in early also and we
started chatting. We manned the Plug booth at Oscon together for a
while also. He was always asking for help on the Plug List  because he
was always wandering off into unexplored territories of configurations
of hardware and software. He was not keen on doing things in the
conventional way. I will miss him.

If you are using Tailscale then you are only going to places inside
your own private network. There is no idea of going outside that
network so there would be nothing for them to monitor or "spy" on.
They in fact do charge if you have a large enough network or want
commercial support. I think you are confusing them with some type of
other VPN provider.

Do you need the static IP for a public facing purpose? If it is just

Google Messages uses the phone as the gateway.  The web app sends the
messages to and receives the messages from the phone. If the phone is
off this does not work. However the phone does not need to be nearby,
just on and connected to the internet and in a cell coverage area.

Limiting how deep to recurse is helpful. You may want just the page

--level= depth
--level=1 would be a good place to start.

Maybe it has nothing to do with the strange character in the filename,
maybe it is set to immutable.

Try
lsattr
if there is an i for immutable then

I find that Firefox works best if installed directly with the FIrefox
official installation. It updates itself and in general behaves better
than any of the packages I have tried. It is always as up to date as
possible and that is more important with browsers than most programs.
Just install from https://www.mozilla.org/en-US/firefox/new/

If memory is not freed when the program terminates, that seems to me

If you want to sample the temperature that quickly make sure you get a

what if stuff was supposed to go to a device mounted there but instead
it went to a folder in /media?

This computer has two drives,

sdb 480GB partitioned as / 84G and the remainder as /home
sda 1GB, one partition, label Data, mounted at /media/jjj/Data

However, there are also two external drives that are always mounted,
Movies (14TB, USB) and Synology (16TB, NAS). I suspect that Movies is
the problem. It is mounted at /media/jjj/Movies, but I think that there
must be some movies there that are not on the drive. Perhaps I moved
some movies to Movies when the drive was not actually mounted. The
Synology is just a backup mirror of Movies (rsync).

Unfortunately, Thunar just displays all the movies in Movies without
telling me if they are really on the USB drive or whether they are
on /media/jjj/Movies. There are over 1400 folders (one for each movie),
so checking each one individually would be ridiculous. I need a more
efficient way to figure this out. Any suggestions?


Umount / disconnect the external drive  and then check to see if anything
is still in the directory where the drive was mounted.

I need reliability & durability more than anything. I'll need it

I'll be going to school for Software Engineering & Embedded

I was thinking about replacing it with a Lenovo ThinkPad T570:

15.6" display

32 GB DDR4 2133Mhz SoDIMM Ram

For the hard drive they show :

Intel 180GB SSD 2.5 SATA3,OPAL2.0
or
512 GB SSD OPAL2.0 PCle-NVMe

(The 1 Tb version is $140 more.)

Q: What is the difference between

SATA3,OPAL2.0 & PCle-NVMe?

As an OS I'll probably be running Linux Mint, I just don't have
time to tinker with new operating bases at this point.

I have used the instructions here
https://www.virtualbox.org/wiki/Migrate_Windows  to migrate Windows XP to
Virtualbox, but have not tried it with WIndows 10.  In summary you boot
into windows and run a script which does some registry magic that makes
your Disk drivers look very generic. Then you shut down, DD the image,
convert it the DD'd image to a virtualbox image and boot it.  It sounds
easy, but it's Windows and every step is fraught with peril.  You should
also boot into Windows and create a Recovery Drive before you do anything
else.
https://support.microsoft.com/en-us/help/4026852/windows-create-a-recovery-drive
After you have a Recovery Drive you might want to shrink your WIndows
installation. I have done this before with a live linux and GPARTED, but
Windows has a native way of doing this now which sounds like a better idea

There used to be a Refresh Firefox feature that resets the preferences

Re: [PLUG] "Installing" the Debian installer - How?

On Feb 20, 2017 5:29 AM, "Richard Owlett"  wrote:

An underlying and/or related question:
Explanation of the "whys" of the "whats" occurring when Linux is
"installed".


_The Background of My Question_
Historically I've been interested in optimizing a minimal Debian install.
My method has been repeated clean installs, sometimes multiple installs in
one
day. I've made enough progress that use of preseed.cfg files improves the
mechanics if the installation process.

Some have questioned why I do this. I've found it a productive learning
experience. I attempt things the normal user wouldn't. My failures force me
to
ask questions.

_The Immediate Problem_
I've become annoyed with the physical mechanics of installing from a DVD
*or* a
flash drive. The installer should be in/on its own partition of the hard
disk
and recognizable to GRUB2.

The closest approximation to an acceptable solution I've found is described
at
https://help.ubuntu.com/community/Grub2/ISOBoot and related pages.

That page is unsatisfactory in at least two ways:
1. It is unclear what is Ubuntu specific and what applies to Linux
generally.
2. Loop mounting an image of the installation CD/DVD obscures what's
happening.
[An underlying goal *IS* understanding how Linux works.]

That the loop mounted installer can be launched by GRUB2 indicates that the
image has everything needed. That a LIVE CD can also launch the installer
suggests that what I want is possible.

The only hint I've had of what needs to be done comes from observing the
output
of update-grub reporting:
Generating grub configuration file ...
Found background image: /usr/share/images/desktop-base/desktop-grub.png
Found linux image: /boot/vmlinuz-3.16.0-4-686-pae
Found initrd image: /boot/initrd.img-3.16.0-4-686-pae
done

Have not been able to correctly apply that hint.

What should I be reading?
Is there something simple I've missed?
Thank you.


How about reading the source code of the installer. That should provide
some definitive  answers to all the above questions.

An email arrived this afternoon from xfinity (Comcast) telling me that

1.

Shut down your computer &
unplug your modem from the outlet

2.

Wait 10 seconds, then plug your modem back in

3.

Wait 30 seconds, then turn your computer back on


Before going through that process I ran the test at speedtest.net on two

Machine Ping  Download Upload
Wife's Win97 17 ms 91.29 Mbps6.1  Mbps
My Ubuntu 14.04  20 ms119.02 Mbps6.18 Mbps

I ran mine a second time and got

   9 ms119.62 Mbps9.19 Mbps


So, without shutting anything down I get better than promised speed on
my machine, and close to it on my wife's machine.

Is there likely to be any change if I shut down my router, their cable

Maybe your router had already rebooted since the upgrades for other reasons
and your tests are just showing the upgraded speeds?

The lm-sensors package has utilities for measuring temperature and fan
speed and setting the fan speed accordingly. That might be a good
place to start. As for your specific error message I don't know what
that is about. It could be what is causing lm-sensors to not  do it's
job.

Try simplifying things. Just write out the long and see if that works. If
so move to the ints, etc and see if you can find out if one of the
individual datum is causing the problem.

Some good work has been done since this article came out.  Version 15 of
openwrt has available a couple of packages which implement a system called
Smart Queue Management that does a good job of mitigating bufferbloat.  The
packages are sqm-scripts and a corresponding luci-app-sqm.

Here is a page about installing and tuning them.

Used routers are easy enough to come by. ISP's regularly update them and
the old ones appear at Goodwill or on Craigslist. If you are careful you
might even find one that supports openwrt. That would allow you to play
around with Linux on your router and network your two laptops together.  A
lot of the newish routers have WiFi, but that can be turned off if you

What router do you have.  Does it have a wireless bridging mode? One type

You will not be using mount.cifs. That is for the windows cifs filesystem.
You will be using something else for NFS.

The problem is not quite that the entire drive is owned by root. The
underlying problem is that you are trying to rsync to a windows type file
system. Or probably more correctly what is presented to you as a windows
file system.  This will prevent you from correctly preserving owners and
groups and such because windows has a different notion of such things.   If
you want to preserve those file attributes, you would be better off
mounting the drive as an NFS drive if the Synology allows for that.

It might even have trouble rebooting.
I am just stabbing in the dark at this point but you can try
umount --lazy /media/jjj/Synology
umount --lazy /mnt

It did not take well to your forced umount. Everything still thinks there
is something mounted at /mnt
Don't really know  how to solve this, but you can try
umount -i /media/jjj/Synology
umount -i /mnt
See if thunar is ok, then try to mount again where you want it.

With that knowledge the mount command would be closer to

mount -t cifs //synology.local/synology/  /mnt --verbose -o user=username

where I still don't know the username and /mnt should already exist or you

If you want to use cp you will have to mount the filesystem. The regular
mount command will do this.  The filesystem type you want is called cifs.
The man page for the requisite options is here
man mount.cifs
A typical command would look like
mount -t cifs //server/share /mnt --verbose -o user=username

One place to begin asking this question is with antenna theory. The basic
question you are asking is what does the radiation pattern of a mobile
phone antenna or wifi router antenna look like if you put a huge plane of
metal above it.  There are debian packages like nec and xnecview  for
antenna modeling. Some of these only allow you to create wire elements, but
some allow  grid or planar elements. Getting an answer that you believe out
of these modelling programs is tricky.

I don't see anything there intensive enough to be causing the problems you

the screen savers. You could disable them for a while and see if that is

I think it means it might not be a hardware problem. Have you done any

Since model trains can be made Turing-Complete you could build a router out

The alsamixer solution should work. After you start alsamixer hit F6 then
choose the right sound device. If all is well the Headphone control will
show up and you can maneuver to it, hit m for mute/unmute, increase it's
volume and it will be working. I have to do this every time I reboot.

Something like this has been mentioned on this thread already, but it's
worth saying again. If you are going to run phone line, you could also run
Ethernet from your current modem (or the router after it) to the other
building. That way you could have internet access in both buildings at the
same time. And you only need one modem.

 Get boot floppy with busybox on it, maybe this one

 Busybox includes dd and nc (netcat).

 Using dd and nc together you can transfer the image over the network

 It will be slower than putting both disks in the same machine, but it

Another possibility is that you have two disk, one of which has an old
version of grub on it and occasionally your system is trying to boot
from the disk with the old grub on it. This can be fixed by installing
the correct grub on all the disks. Make sure you have booted correctly
to your normal working system and run
sudo dpkg-reconfigure grub-pc
choose the defaults until you get to the screen for Grub install
devices: and put a check mark in front of all the disks /dev/sda ,

If instead of a pull model there was a push model then the pushing node
could start the downstream service when it had something to push. Nothing
would be started until it was needed the first time. Also if it can't start
or find anything to push to it can send a message upstream pausing the rest
of the nodesl much like the kill switch in the Toyota production line. No

will have to pause the upstream line occasionally even under normal

There are a lot of monitor power supplies out there with bad capacitors. I

slightly different depending on which caps and the design of the supply.
Perhaps some of the capacitors are on the edge of their spec and small

the monitor and take a look. The bad caps are usually obvious.

 One thing the articles about this problem keep saying and which doesn't
 make complete sense is that this infection is immune to removal.
 There is a method to get the infection into spare sectors and into
 firmware, which seems to me to mean that there *is* a way to see those
 raw sectors and/or firmware in a such a way as to a) see what's there;
 and b) remodify the firmware.

 It might be that if you are dependent on the firmware to inspect or
 replace the firmware, then the infected firmware could just lie to you
 in order to hide itself.  In which case, these devices really need to
 have some offline way of inspecting their flash sufficient to generate
 dumps and checksums to verify they are running what you think they are
 running.

 What tools currently exist on linux to inspect the hard disk firmware?
 I recall updating some hard disk firmware (several years ago), but
 perhaps using a vendor supplied freedos-based software kit.



Also you would think that anything headed for that special area of the disk
would have some sort of signature that could be searched for before it got
sent to the mysterious firmware.

 Robert,

I left out the first 'T' because I did not see 'FT' on the man page; the
 time string is not separated from the date string. Just added the 'T' to the
 format.

What's interesting is that I now see how frequently Frontier changes my IP
 address. Yes, it's unreasonable to change it so frequently, but ... that's
 just the way it is with them. Here's the log since I changed the script
 yesterday afternoon:

Rich,

Are you sure you don't have a bad wire or connector or power cable or
? somewhere between your modem  and the ISP?  Do you have cable or
DSL? What model is your modem?

 As far as I can tell, just running 'less myfile.txt', when myfile.txt is
 being written to by another app, seems to just take a snapshot of
 myfile.txt -- I want to be able to look at the full extent of the file
 AS IT GROWS, to monitor ongoing long computations to see how they're

less itself works that way.   shift-g will reveal anything new added
to myfile.txt after you opened it with less.

 One possibility is that the *remote* web server has reverse DNS validation

 Jim,

Easily found with whois, host, and dig on the domain name. However, since
 you made me see what I overlooked before, the IP address for this domain is
 static; it points to the server hosting my web site at my ISP. It's only the
 mail. IP address that is dynamic since mail comes directly here.

 Almost all ISPs provide PTR records for their dynamically assigned pool
 addresses. For example, my (obfuscated) IP is aa.bb.cc.dd and if I do a
 dig -x on it I get:

This morning a message from the GRASS coordinator said that the web server
 had hardware issues that slowed response times. Why my location should seem
 to be the only one consistently affected will probably never be known.

No PTR record returned by dig, only the SOA:

 If your ISP has not provided a PTR record for your address, then it's the
 SERVER that could be timing out on DNS resolution trying to figure out who
 you are (for blacklisting, for instance). It's pretty rare nowadays to
 configure a web server to do PTR lookup (email servers yes, web servers
 no) but it would cause exactly the behavior you are seeing.

Perhaps that's it.


To my eye this dig result fits Jim's explanation perfectly. The
webserver is doing  a reverse DNS lookup for some reason. Maybe for
blacklisting or maybe just for logging.

This article describes how you can accidentally configure Apache to do
this by putting in an Allow from localhost directive.
http://blog.endpoint.com/2013/09/apache-accidental-dns-hostname-lookups.html

This problem could resolve itself because your IP address is so
dynamic. It might randomly change to an IP address that has a PTR
record and then suddenly you will be able to load the website
normally.

The idea is that the grass.osgeo.org webserver is looking up the PTR
record for the external IP address  of the machine that is running
your web browser.
In your case it is the same as your MX address.

host mail.appl-ecosys.com
mail.appl-ecosys.com has address 50.38.89.212

dig -x 50.38.89.212

 John,

I have not.

 If it makes it all the way through then there's a problem with your
 browser. Are you using ad-blocking strategies? Maybe redirecting known ad
 sources in a way that would cause a request to appear to hang?

Same problem occurs with firefox, opera, chromium, lynx, and links.
 Adblock runs only on firefox.

And this is the only web site I've tried accessing that has this issue,
 and I first noticed it only last Saturday. Always connected as quickly there
 as other sites before Saturday ... but it was a while ago when I last
 visited there.


How about trying from a different machine, a laptop or another desktop?

 wes,

It is quite irrational, I agree. That I could not load several of the
 mirrors may or may not be a related issue.

At least now I can access a mirror site so I'll wait to see if something
 changes back in the future.

Age discrimination? :-)

Very likely just makes them load slower and look slightly blurry.



Only some of the mirrors work for me also. Do these match up with what you see?

USA Tier 1 http site
http://mirror.quintex.com/grass  does not load

http://grass.meteo.uni.wroc.pl/works

http://grass.unibuc.ro/   404

http://grass.milthi.me/works

don't see any listings for French, German or Italian mirrors on the

What makes you think they installed Ubuntu on the hard drive? You gave them
