Didn't even try, I just take whatever Debian does by default.

Any such tool you are using has to be regularly updated as well and by 
definition is built on the assumptions of the developers of what is 
(not) necessary for me. This can easily lead to a false sense of 
security.

There are sufficient tutorials advising to download random scripts and

Would be the same on Debian if you chose to install additional software 
with some other package manager and debs downloaded from whatever 
website.

This is just a side effect of Linux being much less common on typical[1] 
desktop / laptop systems.

You probably mean Linus's law[2]. Unfortunately the reverse is true as 
well: without sufficient eyeballs there will be many bugs.

If something like Heartbleed can happen to a widely deployed software 
imagine what is probably hidden in all the software with a much smaller 
user-base and almost no active maintenance.

In my opinion any system can be made very secure, but not 100%.

The given/chosen hardware and software can make some things easier while 
making others more difficult.

The FLOSS ecosystem has a slight cultural advantage: less reliance on 
tools to stop and/or detect malware. Instead the vulnerability is 
(hopefully) found and patched.

This advantage is partially due to Microsoft's security practices in the 
past. While these have improved significantly in recent years some 
practices are difficult to change and will probably only disappear 
together with the desktops and laptops[3].

[1] not including Chromebooks
[2] https://en.wikipedia.org/wiki/Linus%27s_law
[3] fortunately when new types of devices like smartphones and tablets 
were introduced the hardware and software makers used the opportunity to 
also introduce better security models and practices, unfortunately 
together with an entire class of new privacy issues.

Kind regards,
Andrei

X framebuffer problem on AMD Picasso

[Paul Scott]

Hi,

I haven't posted for a long time!

I just successfully did my first UEFI installation.

It's a new AMD machine with.  X is failing to start.  I have solved a 
number of related problems within online information including finding 
the firmware-amd-graphics package.  I can't easily post log contents 
from that machine since it doesn't have email installed yet.


I am now at:

open /dev/dri/card0: no such file...

What I find online refers to the firmware problems I think I have solved.

TIA for any ideas,

Paul

I don't think anyone has tested, but you could try ReactOS

Of if you happen to have an Android or iOS device, they
work fine.

There is at least some success reported running Webex within Wine:

I'm also sure it would work in a virtual Windows session, if you happen

And I have discovered a way to have a fixed IPv4 address. My router's mac 
which I have cloned into a second emergency router, is how they assign 
an ipv4 address to me, net result has been a fixed dns address, so I am 
now on my 3rd 5 year registration of a namecheap address with 
geneslinuxbox.net.  So you can click on the link in my sig, and get this 
machine for the last 11 or 12 years w/o me haveing to pay for the much 
higher dynamic address I really am.

Sound issues on ThinkPad X220T (Lenovo)

[riveravaldez]

Hi,

I would like to know what's the proper way to solve this. I'm on an
updated debian-testing installation (with pulseaudio installed and
working, but the problem seems to be previous, i.e., in ALSA, because
pavucontrol doesn't show the soundcard in its correspondent tab).

I can get audio from audacity and audacious as long as I choose
manually the proper soundcard in its options, but not from other
programs (e.g., firefox, mplayer, etc.), which I suppose use the
default soundcard.

Strangely, 'speaker-test -c2' doesn't produce a sound. But 'sudo
speaker-test -c2' works flawlessly. (The idea to check that came from
[1].)

I already tested (following [2]):

$ sudo alsactl init
Found hardware: "HDA-Intel" "Conexant CX20590"
"HDA:14f1506e,17aa21db,0013 HDA:80862805,80860101,0010"
"0x17aa" "0x21db"
Hardware is initialized using a generic method

But nothing changed after reboot. (Though, the CX20590 is the working
choice for audacious/audacity.)

I have this info:

$ cat /proc/asound/cards

Upstream releases (these evidently happen about every fifteen minutes
but I only upgrade every few months or so).

I don't lose anything.  I just have to go through a silly song and dance
to import my old profile (which took a bit of research to discover as I

That's what I'm talking about.  The process consists essentially of
creating a new profile and importing the old one into it.  A pointless
song and dance that Firefox could do automatically in the background.
At the very least they could offer a simple dialog along the lines of
"Which of these old profiles do you wish to import?"

There was no warning when they started doing this.  The first time it
hit I was told that I should import my old profile via my nonexistent
"Firefox account".  Not going to happen.

GeoIP usually (though not always) puts me in Elk Mound because that's
where the CenturyLink concentrator that I connect to is located.

Before the exhaustion of the IPv4 space (and before classless routing)
you could always tell what country and what ISP an IP was in by
inspection.  ISPs tended to distribute IPs hierarchically and
geographically internally, so it didn't take too much research to
develop fairly reliable databases.  Classless routing plus the buying
and selling of small blocks of IPs has destroyed that relationship.
It's also exploding the routing tables.

My firefox profile is never lost.
 
I copy my .mozilla directory and take that with me to another town.
On the PC there I replace my .mozilla directory and start firefox:

Result:
Everything is restored: history, bookmarks, settings, logins/passwords, 
even the open tabs.

When I return to my town I take with me my new up to date .mozilla
directory.

Firefox is a very convenient browser nowadays.

I do not take my entire home directory with me, for some reasons.

PS. I believe you have to use the same version of firefox on both
machines for this to work.

My feeling is that running as root is considered an extreme no-no in
Linux (probably apart from the toy distros) and it is this that makes
Linux viruses non-viable. There just aren't enough infectable targets.
(Most) Linux users are horrified by the thought of surfing the Web with
root privileges, most Windows users are not even aware that their
computers can be run at one of two privilege levels (many more with the
business/professional versions).

Even today, with a new Windows 10 installation, the first user is given
root privileges by default, and no advice is offered about demoting the
user to unprivileged later.

About fifteen years ago, I used to help out on a Small Business Server
newsgroup (later web forum) and I was amazed at how sloppy many other
helpers (including MCSEs, which I wasn't) were as regards security.
What really didn't help was the need for each user of a workstation to
open the Office applications for the first time with root privileges,
otherwise some initialisations didn't happen. Lazy admins just gave all
the new users root privileges for a week or two to let them sort it out.
You can't win against that kind of mindset.

What sort of upgrade? Just the regular security fixes (which seem to
be quite frequent recently), or point-releases, or what?
And what parts of your profile do you lose? Bookmarks, cookies (like
the ones you might want to keep for logins) or what?

It's just that I've been using the same two profiles (two users) for
years. I've copied them from machine to machine as my principal
workstation has changed, and I copy them to other machines so that
I don't have to find lots of websites I use fairly regularly. (They
gradually diverge, of course, from the canonical copy on my principal
workstation.)

Some of the files in the profiles are pretty ancient and obviously
were converted into other formats but not cleaned up. I mean, what
do these do?

yes this is true, but the bottle neck could be the cache or the disk IO. If
you have slow disk, RAM can be advantage. If it is the cache, may be it is
time to upgrade the system (cpu and/or mainboard).

For me personally the most impressive boost was the SSD. I do not have any
CPU or RAM hungry applications - except when compiling but this is done on
a server, so the desktop is not affected. 8GB RAM is sufficient for the
desktop. If I put another 4 or 8 it will consume them with time as well.
This is what modern Linux kernel does. It will free memory whenever it
needs. But I would not have big addvantage.
On the PC I call "the server" I started with 16, but because of running
virtualizations I upgraded to 32.

Sheffield is a city well into the North of England.

Here's geoip.com:

England
Washington

This isn't the original Washington, which is in East Anglia, this is a
tiny village near the south coast of England.

And I live in the easternmost London Borough. So much for accuracy. My

Re: Anti-malware for my personal Debian workstation?

[l0f4r0]

Hi,

Thank you everybody for your answers.

I understand most of you respondents don't use anti-malware at all. A good 
hygiene or other kind of solutions like system hardening (AppArmor, SELinux) 
are way more efficient.

NB : I've been told SELinux is so complex, people eventually let it drop... Do 
you all succeed in configuring & using it? ;)

Do you follow any guide or tool to help you in hardening your Linux distro?
I've used Lynis for the audit part, it's nicely done. What do you think about 
it?

Anti-malware on Windows is common/best practice. However, as we are discussing 
it here, things seem to be different with Linux. I don't really think Linux is 
intrinsically more secure than Windows nowadays (a vulnerability remains as 
such) but I really think Linux ecosystem is. Here are some reasons that could 
explain that according to me:
* Most softwares are downloaded through official preconfigured repositories. 
Users are less prone to download malware on suspicions websites
* Updates are easier as well because tracked/centralized through repositories 
themselves for the most part. On Windows you need to check Windows Update + 
Windows Store + each application individually
* Linux users are globally more tech-savvy so they take care more about their 
systems
* Open source is more common on Linux (community-based) than Windows 
(money-based) so theoretically anyone competent enough could view the source by 
oneself and spot a malovelent behavior (/!\ in practice this is not so easy, 
see what happened with OpenSSL / HeartBleed)
* Linux desktops are less exposed : it's more lucrative for black hats to 
target Windows users with malware (see desktop marketshares). However this is 
only half of an argument because Linux server marketshares are quite the 
opposite!
* Until some years ago, I would have added that Linux is more secured by design 
(least privilege, compartmentalization) than Windows but I think this is not so 
true now, Windows has cought up apparently...
=> What is your opinion?

Thank you & Best regards,

Less distant to gparted would be sfdisk. It'll let you access
disk partition tables. But it's not automatic either. And then
there's blkid, which will make educated guesses at which block
devices are out there (results might depend on you being root,
some cache states and perhaps moon phase ;-)

Worked for me.

Apparently, I'm on top of Nelson's Column (London, England).  In
reality, I'm about 160 miles west(ish) of there.  I surmise the location
is based purely on the postal town of my ISP.

That puts my IP in West Sussex.  Still a long way off from where I am.
Based on where my ISP connection is located, I think.

BTW, I fed my IP address to this site

 https://www.maxmind.com/en/locate-my-ip-address

and it nails my location approximately within a 50 meter radius (I
entered the latitudinal and longitudinal coordinate output into Google's
search engine, which brings up the spot in their Maps app).

I found this surprising (in my vast ignorance).

At what level of granularity (country/city/neighborhood/street)? 

I don't know how precise a geolocation by IP address could be where
you're residing in Columbia, given the ISP you use, and maybe other
factors upon which that precision depends.

Sorry for the unwarranted assumption this was the same machine as your

Answering "yes" here would be a gross oversimplification.
Answering "no" here would be a deviation from the truth.

I'd say it this way:

1) Your instance of GNOME Maps connects to nominatim.gnome.org by using
https. Your local IP address does not matter here, as long as the
connection gets established.

2) Due to the way your home network is made (it's called NAT), nobody
sees your computer IP but your router (or the router provided to you by
your ISP).

3) What's nominatim.gnome.org is seeing is the IP that's used by your
ISP for outbound connections on your behalf. It may be the same IP
that's your router is using for the WAN port, it may be different.

4) If you're interested what is your outbound ip - I suggest you to use
some Internet service like https://www.whatismyip.org/ . 

IP from pt 3 is enough to pinpoint your location with the country
precision at worst, city precision at best, and by the very definition
of what's happening here this information is available to you (via GNOME
Maps) and to the nominatim.gnome.org.

I do not GNOME Maps so I cannot comment on if it's possible to disable
this feature without rebuilding GNOME Maps from the source.

It's so called "ephemeral" port that's used on your side for the TCP
connection, and it's the usual thing.

What's important here is that confirms that GNOME Maps is using
aforementioned library for the purposes of establishing your location
regardless of the GNOME privacy setting.

Personally I see it as a privacy violation, but someone may see such
(mis)feature as a crucial function of GNOME Maps. In any case, a bug
report with the severity of "minor" can not do any harm, so I suggest
you to install "reportbug-gtk" package and report your findings in a
"gnome-maps" package to Debian's bugtracker.

This may mean that requests for location service by a browser or a script

Regarding the precision of location. I do believe it might depend on
the ISPs and the country those ISPs are in (there must be laws
regarding this). I am saying that in Colombia, the ISPs have a very
detailed location map based on IP. I am a newbie and do not know a lot
about this.

I believe you :)

I wasn't implying anything -- I was just musing about how complexity
tends to kill understandability. It's somewhat disheartening how we
do and promote free software to have users in control, and then, by
just piling gadget upon gadget we make that goal more difficult.

I have no idea on how to solve that.

So. I right now physically in the beautiful city of Cali, Colombia. And
Gnome Maps is showing my location precise to about a 10 meter radius of
my actual location. That is my concern. Location Services are Off and
have never been turned on on this machine.

This is precisely my issue. I set Location Services to Off in Gnome
settings. And then a Gnome app, like Gnome Maps, provides me with my
location. If you can advise me on how to report this to the Gnome
people or to the relevant Debian team, I would gladly do so.

No Curt. This is not the case, this is a different machine, with a new

I actually now believe you are all right. It is getting my location
based on my IP, I believe this because I don't know of any other easy
way of getting my location. I am on a laptop that does not have a gps
device, nor is it connected to some kind of phone network.
My question remains, why is a Gnome app not respecting the settings I
am inputing in Gnome? (Location Services: Off)

Thanks for the reply -- interesting.  

Two of my machines (Wheezy and Buster) don't have L3 cache, my Jessie machine 
does.

I see varying definitions / explanations of L3 cache -- some say it is on the 
CPU die, and some say it is on the motherboard (but, in either case, one level 
further away from the CPU(s) (mcow).)

And, also in either case, not easy to upgrade short of replacing the CPU or 
motherboard.

RAM is still (to me) the most cost effective upgrade to an existing system.

(I guess I could mention that I don't play games, so video performance is not 
a key for me (and, when I do / did play. games, video performance was not a 
key -- games like FreeCiv and such).

I am considering a new machine at this time, a laptop with a good docking 
system (I'm looking for one with a USB-C port) so that I can easily undock it 
and take it to meetings, but use it at home for development with GCC 8 (or 
high 7) -- I want to do some work on a program (scintilla) that now uses 
features of C++ versions 11, 14, and 17.  (And I was thinking of taking the 
laptop to meetings where I might get help, but who knows when any such 
meetings will take place again.)

(I actually bought a machine (mail order that advertised a USB-C port but have 
to return it as it doesn't have a USB-C port.)

I guess I should say that I don't have objectional performance with any of the 
machines I have -- well, maybe I should take that back -- I keep the Wheezy 
system as my daily driver for several reasons -- including laziness, but also 
it seems better performance with kmail and firefox.

When I have as few as 10 to 15 tabs open on the Firefox on my Jessie system, 
Firefox crashes (I mentioned in a previous post in this thread having a 
thousand or more tabs "open" in Firefox on Wheezy with minimal problems -- yes 
occasional crashes (maybe once every 2 to 4 weeks?), but I couldn't come near 
that on Jessie, and I expect the same problem on Buster.

I guess that is all related to Wirth's law (and variations, Gates', ...).

Back in the old days (when I found my computers slower than I liked), I found 
that adding more RAM was usually a better approach to improving performance 
than getting a faster CPU.  Not sure how to quantify that, but I like to have 
at least 12 GB in any computer I use.

That was especially true when CPUs started to reach the point (around 3 GHz., 
iirc) that their improvement in speed slowed down.  (But it was also true 
before that.)

If I had a computer that I was dissatisfied with the performance, I would 
definitely add RAM to try to get up to 16 GB or so.  Only then would I think 
about getting a faster CPU.

Aside: The idea of extra cores sounds good to me, but I don't know how much 
software actually takes advantage of this (or if the OSs / kernels) are 
typically smart enough to distribute tasks across multiple cores -- I hope 
they are, but really haven't been paying attention.

I think my bottleneck these days is again RAM, on my daily driver I have 16 
GB, but sometimes have 1000 or more tabs "open" in Firefox (on Wheezy).  
("Open" is a little misleading -- occasionally Firefox crashes.  When it does, 
I restart it and choose the option to restore all tabs (or whatever it says), 
the old tabs show up with their names, but the content from those URLS is not 
actually loaded (or fetched) until I click on one of those tabs to view it 
again.

(Actually sort of a nice feature -- it lets me keep easy access to lots of 
pages without filling up RAM.)

Re: Can't get my Debian laptop to use my Radeon 520 Mobile graphics card

[Jörg-Volker Peetz]

Try it without any /etc/X11/xorg.conf file and read the Debian Stretch part in
the Debian wiki. What's the output of the "xrandr" commands listed in the wiki?

Regards,
Jörg.

Would the amount of RAM affect browser JavaScript performance? Is that
due to JIT compiler results not being able to be cached or something
like that? I've just assumed slow performance it due to CPU throughput.

It would be interesting to know if there is an appreciable difference in
precision between Maps and Night Light before you fixed the latter's
imprecision (about which you complained in another thread here) by
presumably feeding it manually your latitudinal and longitudinal
coordinates. Because one would assume both apps would use the same IP
method to locate the user for the case of a user whose geolocation
services have been toggled off (or never toggled on) in his privacy
settings.

Of course, David W. is right (and also Wright!) to say we don't know
what you mean, exactly---at what level of granularity is Maps locating
you precisely (country/city/neighborhood/street/apartment
building/etc...)?

Rather than positing some egregious violation of user configuration on
the part of Maps, I was theorizing in an earlier post that a precision
on its part that couldn't be explained by simply inference from your IP
address might possibly be explained by Night Light sharing the
coordinates you provided it not long ago (if indeed you did do that, as
you never stated this explicitly, either). Whether that would be a bug
or not remains unclear to me.

Localhost is the machine running Apache. The normal IP address for it

If you install Apache2.X on Debian, do nothing else at all, and enter
just 'localhost' in a web browser address window (running on the same
machine as Apache) then you will see the Apache 2 Debian Default Page,
at /var/www/html/index.html which basically shows that Apache is
running, and gives a few details about configuration.

If you can see this page, or whatever you may have replaced it with,
then Apache is running, which is half the problem solved. Always check
this first if you have problems (I leave this page in place, despite the
encouragement to replace it) as Apache is quite fussy, and will refuse
to run under some conditions. If it's not running, check
/var/log/apache2/error.log for the reason.


Joe, I thank you for the explanation.  Because "localhost" did not
display the Apache2 Debian default page, I began by reinstalling
Apache, whereupon the page was displayed.

Next, I checked the local file with my alias declarations, and in it I
found an error.  Then I checked the configuration file in
"/etc/apache2/conf-available" which points to the local file.

After enabling the pointer file, "systemctl reload apache2" failed to
restart Apache.  But systemctl suggested I run "journalctl -xe", and
journalctl pinpointed the line number with the error.  I also looked
at "/var/log/apache2/error.log", but it was not as helpful.

I quickly found the remaining problem (a dot rather than a hyphen in a
file name), and now things are running right.  So at last I can return
to the tutorial.  Again, thanks.

As far as I can tell it depends a lot on the ISP.

My current one apparently maintains its database down to city level... 
and then allocates those IPs dynamically all over the country :) 

My previous ISP was allocating pseudo-static IPs with location as 
accurate as city area.

Kind regards,
Andrei
