The sister of a friend is a vet. She has blood analyses equipment which
sends analysis results to a serial port. Each brand and model has it's

Recently she acquired Skyla VB1. This device has both a serial port and
Ethernet. It sends a ^A to the serial port, expects a ^F and then sends
the data followed by a ^D, after which it expects an other ^F.
I did manage to get data from the device this way.

The device can also use the ASTM protocol. With ASTM it can also use
Ethernet. Which is more practical.
I could not find a free version of the ASTM standard. Apparently, there
is some Linux software which supports ASTM, but what I could not find is
a nice overview.

Hi Rob,

OK. Now I understand a little bit more the situation.

You are referring to this pattern:
https://www.astm.org/Standards/E1381.htm  


I didn't know this standard.

What I have seen in my experience with laboratory automation with some 
instruments/equipment is that each manufacturer has its own ASCII communication 
protocol.

Therefore, it is more viable to use some standard to specify a communication 
interface but without specifying the specific protocol of each 
equipment/instrument.

The only ASTM standard for laboratory automation with this approach (define 
interface) was the LECIS standard, which is now discontinued:
https://www.astm.org/DATABASE.CART/WITHDRAWN/E1989.htm

I discovered, a few days ago, the SiLA project to standardize automation in the 
laboratory:
https://sila-standard.com/

But I still don't know the details.

I have already had to implement programs for serial communication with 
instruments and equipment in the laboratory.

But I don't remember seeing any Debian packages related to this ASTM standard.

I've found some programs for acquisition and graphic display of data received 
through the serial port.

But as they didn't have all the resources I decided to develop my own programs 
using the Tcl/Tk language, always using Debian.

I tried to document some of these projects on my website, which might be useful.

The material is in Portuguese but it is possible to translate it with the help

Hi Dan, Yes, you are right, it is not a specific Debian issue.But I 
don't know where to ask for help. I'm having trouble finding reliable 
answers to configure this router.There are many videos on Youtube but 
with contradictory information.I searched on the TP-link website and 
posted a question on the forum but I didn't have an answer.I did what 
you suggested, but throughout the day the speed varies. So my 
question is, what a speed value mean if it varies throughout the day?


I think you're getting into fundamentals of how your internet is 
provided. I'm not a networking engineer, so some of the detail of the 
following might be off, but this is how I understand it to work. The 
most popular broadband around at the moment is ADSL. This is, in VERY 
broad strokes, an extension of the older analogue modem technology. 
But, instead of the data being modulated into audible sound, it's 
modulated into ultrasonic sound. Instead of dialling into a server 
halfway across the country, with ADSL the sound only needs to carry as 
far as your local telephone exchange. Blocks of frequency, all above 
human hearing, are used and the total frequency range (and therefore 
data bandwidth) is MUCH higher than before. (Incidentally, because 
ADSL is fully above human hearing, this is why we can use a 
"microfilter" to split the data and voice frequencies, meaning you can 
use your phone without disrupting the internet).


Now, here is the first reason why the speed can vary throughout the 
day. ADSL is, fundamentally, trying to push wires which were only 
rated for voice frequencies beyond their limits. Sure, all data 
transmission technologies have an analogue medium, but Cat5e Ethernet 
cable is designed to fully handle the frequencies being passed across 
it. The copper phone lines to your telephone exchange might be half 
buried in water, they might run alongside a train track, they might 
follow the twisty route of a suburban road, rather than taking the 
most direct route. The upshot of this is that the amount of noise on 
your line probably isn't constant. Your ADSL modem will be constantly 
monitoring the signal-to-noise ratio of the various blocks of 
frequency, and the two ends will negotiate which to use. To put it 
simply, bad weather can reduce your bandwidth.


Another issue that might affect your speed is "contention". Contention 
is a more broadly-applicable issue. You see it on ADSL broadband, but 
you see it more commonly on Cable broadband. Contention basically 
means that some part of the connection between your house and the 
ISP's central servers is oversold. Taking the ADSL system as an 
example, let's put ourselves in the shoes of a fledgling ISP. We are 
provisioning a neighbourhood for ADSL. Let's say that, theoretically, 
ADSL can go up to 50Mbps per line and that there are 100 houses being 
served by this one exchange. That means we need a 5Gbps link between 
the exchange and our servers, right? But they're SO expensive! And, 
no-one's actually bought ADSL yet, let alone the "Top Speed" package. 
If we buy the 1Gbps link, we can save massively. So, people start 
buying  ADSL and they're getting 10Mbps speeds. Wow! That's fast 
compared to 56kbps! 20 people buy it. 50 people buy it. Excellent, 
we're still only at half the capacity of our big link. Oh, but here's 
a technology update and ADSL can now reach 25Mbps. As you can see, as 
more and more people buy ADSL, and the ADSL routers get cheaper and 
faster, the pressure on the uplink increases. Now, as this happens, 
your ADSL modem will still report the fast speed. As far as it's 
concerned, it's established a, say, 25Mbps connection with the 
telephone exchange. Now, if it's 3am, perhaps you CAN download at 
close to that speed. But what if it's 7pm? And it's the season finale 
of "Lilliput's Got Talent". Suddenly, you've got dozens of people 
trying to download masses of data. Everyone is still connected to the 
telephone exchange at high speed, but the over-sold uplink can't 
transfer all of that data, so everyone's bandwidth

This isn't really a Debian issue, but let me take a stab at it:



Disconnect network A. Run a speed test.



Connect network B, disconnect network A. Run a speed test.



Connect network A again, and now you have values for A and B to

Hi Ming,


That's right, I think I need to choose an "input method".

I'm gradually understanding what I need.

I found a tutorial that explains what the input methods are.

http://xahlee.info/kbd/chinese_input_methods.html


 From what I've seen the most popular method is "pinyin".

I installed:

apt-get install fonts-arphic-bkai00mp
apt-get install fonts-arphic-bsmi00lp
apt-get install fonts-arphic-gbsn00lp
apt-get install fonts-arphic-gkai00mp
apt-get install fonts-arphic-ukai
apt-get install fonts-arphic-uming

and

apt-get install ibus-pinyin

Please, what I should do now?

Since I am not currently using a debian system with GUI, I may not be
able to guide you in detail.

But in most cases, you just need to find the ibus settings/system
languages setting (with GUI), add an input method, and finally logout
and re-login. Then you can use shortcut keys or click the input method
icon in status bar to switch input methods.

I find some tutorials in Debian Wiki that might can help you:
https://wiki.debian.org/InputMethodBuster
https://wiki.debian.org/I18n/ibus

And this Arch Wiki may also be used for reference:
https://wiki.archlinux.org/index.php/IBus

In addition, I noticed that ibus-pinyin is deprecated, you may
need change to ibus-libpinyin.



Hi Ming,

I followed your tips:

In the Preferences menu -> ibus preferences -> Input method -> Add, then 
I selected Chinese and Pinyin.


And to insert ideograms I just activate Chinese - Pinyin in systray 
(bottom right of desktop)


http://www.c2o.pro.br/download/Linux/Chinese/ibus_prefences_add_pinyin.png
http://www.c2o.pro.br/download/Linux/Chinese/ibus_preferences.png
http://www.c2o.pro.br/download/Linux/Chinese/select_input_method_at_systray.png

Then I saw your tip for replacing ibus-pinyin by ibus-libpinyin.

I was in doubt if I should remove the ibus-pinyin first so as not to 
conflict, but I found at


https://askubuntu.com/questions/502811/why-my-ibus-input-cant-type-que-or-qve-in-chinese

the tip for just install

apt-get install ibus-libpinyin

and change the input method but not removing any packages.

If Chinese cannot be displayed normally on your computer, you may need
a font. But with your description, you might just need an input
method?

For fonts, I recommend WenQuanYi(??), it is a very good open
source Chinese font. Just use the command to install it (actually, it is
a set of fonts with different styles, you can choose to install
according to your needs):

apt install fonts-wqy-microhei
apt install fonts-wqy-zenhei

If what you actually need is an input method, I think ibus may be a good
choice, you can configure Chinese input through its GUI.
I actually use the ibus-rime(a rime input method engine encapsulated
using the ibus framework), but it may require more manual configuration
and is not suitable for beginners of a language.

It could well be worth your while to get on top of LaTeX, through the
Texmaker editor or similar.
Install the font programmes you require, and employ Babel.
You can employ both languages within the same document.
It's what I do.
It's not such a learning curve, but it depends on how serious you are.

/etc/NetworkManager.conf

[device]
wifi.scan-rand-mac-address=0

Now the file /etc/NetworkManager.conf is:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=0

Now itconnects to the network but does not navigate. :-(

I could check, for example, that it is not creating the file 
/etc/resolv.conf


which indicates the Gateway address.

Continuing my searches, I found information that there is a conflict 
between Wicd and NetworkManager.


I decided to remove Wicd with the commands:

apt-get remove wicd

sudo apt-get remove --auto-remove wicd

But it did not solve the problem, and even the ifconfig command is not 
working anymore.


I think I just made a mess. :-(

Any tip?

Thank you,
Markos

TPLink WN722N and WN823N can find wireless network but can't connect to it

[Markos]

Hi,

I'm trying to use these two adapters on a desktop with Debian 9.

I installed the firmware:


|apt-get |install| /|firmware-realtek|/|

|/|And the Network Manager|/|


|/||apt-get |install| /|network-manager-gnome|/||/|

I open the applet in |/||/|system tray to select wireless network in the 
list.|/||/|


|/After to click the desired network I enter the password and click 
"connect" button./|


He tries to connect for a while but can't.

Please, how can I try this connection by command line interface (CLI) to 
identify the reasons for not connecting and troubleshoot it.

Re: How to set access permissions to protect a database file?

[Markos]

Many thanks to Mick, David and Joe,

To guarantee "some" protection to the file containing the database I 
decided to use the following strategy:


I created, as root, the directory /home/reading_room

And activated the "sticky bit" of the reading_room directory with the 
command:


chmod +t /home/reading_room/

And transferred, the files to the new directory with the following 
access permissions:   


reading_room.tcl  rwxr--r-x  (owner markos)

reading_room.db rw-r--rw- (owner markos)

This way other users can run the reading_room.tcl program but can't  but 
not edit.


And can't delete the files (.tcl or .db)

Trying to protect against Murphy, but not Machiavelli.

Thank you,
Markos

I never did anything on a PC with other people having access so I 
never made a file only executable by anybody but I don't see why not.

As you wrote reading_room.tcl presume that belongs to you.
I don't know anything about tcl as yet but assume it's executable as 
it is and does something.
You may have a group librarians that want to have read/write access 
to reading_room.tcl

Assume you have backups of the files.
guess books.db wants to be 644
"su -"
"chmod 644 books.db"

"chown you.librarians books.db"

I don't believe there is a solution using just read, write, and mode
bits and group membership.  (Perhaps, there is a solution if you also
use access control lists?)


Suppose I have a Perl script "shared-program.pl" (sorry, I don't know
TCL) that reads a line from the terminal, lower cases the line, and
then writes the line to the terminal.  If the line contains the word
"write', the line is also written to a data file "shared-program.dat":

2019-05-25 20:31:43 dpchrist@tinkywinky ~
$ ll sandbox/perl5/shared-program.pl
-rwxr-xr-x 1 dpchrist dpchrist 267 2019-05-25 20:31:35
sandbox/perl5/shared-program.pl*

2019-05-25 20:31:49 dpchrist@tinkywinky ~
$ cat sandbox/perl5/shared-program.pl
#!/usr/bin/env perl
use strict;
use warnings;
use FindBin    qw( $Bin );
use File::Slurp;
use constant DATAFILE => "$Bin/shared-program.dat";
print "$0 >";
my $line = <>;
$line = lc $line;
write_file(DATAFILE, {append => 1}, $line)
    if $line =~ /write/;
print $line;


If I run the program as the owner, it works as expected:

2019-05-25 20:34:01 dpchrist@tinkywinky ~
$ sandbox/perl5/shared-program.pl
sandbox/perl5/shared-program.pl >Hi, Dave!

2019-05-25 20:35:22 dpchrist@tinkywinky ~
$ cat sandbox/perl5/shared-program.dat
write bye, dave!


The mode of 755 on the script allows other group members and all other
users to run the script:

tinkywinky@tinkywinky:~$ /home/dpchrist/sandbox/perl5/shared-program.pl
/home/dpchrist/sandbox/perl5/shared-program.pl >Hello, Tinky Winky!

2019-05-25 20:38:08 dpchrist@tinkywinky ~

Other users are not able to run the script because the Perl
interpreter cannot read the script:

tinkywinky@tinkywinky:~$ /home/dpchrist/sandbox/perl5/shared-program.pl

"/home/dpchrist/sandbox/perl5/shared-program.pl": Permission denied

Printer pull half of a second blank page after the first printed page and stops

[Markos]

Hi,

I am having problems with my HP Laserjet 1020 printer installed in 
Debian 9 "Stretch".

I installed the drivers from: http://foo2zjs.rkkda.com/

||bash$ | wget |-O | /|foo2zjs.tar.gz 
http://foo2zjs.rkkda.com/foo2zjs.tar.gz|/|

||bash$ | tar |-xzvf | /|foo2zjs.tar.gz |/|
||bash$ | cd /|foo2zjs |/|
||bash$ | make |
||bash$ | ./getweb 1020 |

and

||bash# | make /|install |/|
||bash# | make /|install-hotplug
|/|

...

It worked normally for about 5 years, but suddenly started the following 
problem:


When I print multiple pages, it prints only the first page and pulls a 
second blank sheet until the half of the sheet and stops.


To remove the sheet I need to turn off, remove the toner cartridge and 
pull the sheet.


Any tip about what may be the cause of this problem?

I suppose that this comparable to install a Firefox extension via

Do not take my word for it, though: I have absolutely no competence in

Using pip is like building non-python software from source when it is
already packaged for Debian -- possible, and occasionally necessary in
some circumstances, but to be avoided where you can. If you use the
Debian packaging system, Debian knows what you have installed and what
libraries your system is dependent on, etc, and won't do anything to
break your system for example when you upgrade. But if you install using
pip Debian doesn't know anything about it (so won't upgrade it for you
when you upgrade). In particular, but not limited to, upgrading a system
that has a mix of manually-built and Debian-installed packages can be a
pain.

I can tell you from experience the version of matplotlib in Debian 9,
while not the latest and greatest, is plenty good enough. I use it quite
a lot.

If this is you making a foray into data science with python, by the way,
I also strongly recommend the pandas library (also in Debian, and again
the version in Stretch is not latest but plenty new enough).

failed to load iwlwifi-7265D-26.ucode but wifi works

[Markos]

Hi,

I installed Debian 9 with Debian-live-9.4.0-amd64-lxde+nonfree.iso.

But during startup I see messages that the system can not find the 
driver for the wifi card. (dmesg bellow)


But despite that I am getting access to the wifi network.

My question is whether I should leave it as is or should install the 
package firmware-iwlwifi.


But if I install this package could it generate conflict with the driver 
that is already working?


Thanks,

Just copy abook.mab from the old to the new. But see below because you

Export/Import is great for archival or migrating between different 
email clients, but I found copying raw data files to be the most 
convenient when going between Thunderbird instances. However, 
automigration is likely what you want.


The official way of migrating is to copy your *entire* ~/.icedove 
directory to your new computer.


tar zcf icedove.tar.gz .icedove
# copy icedove.tar.gz to new computer
tar zxf icedove.tar.gz

Since the Icedove->Thunderbird unrebranding, the first time 
Thunderbird starts with no ~/.thunderbird (if you already have a new 
one you can remove or rename it to, for example, 
.thunderbird.disabled), it will automatically migrate *everything* 
into a new ~/.thunderbird directory. All your account settings and 
plugins should just work. You should then be able to remove your 
copied ~/.icedove directory and any renamed empty (e.g.) 
~/.thunderbird.disabled. There might be another copied temporary 
icedove directory because Thunderbird will try hard to not harm your 
data.

Hi,

Thanks for all replies.

I followed the procedure:

To transfer the address book (Source: 
http://kb.mozillazine.org/Move_to_a_new_PC):


In the old micro: Tools -> Address Book -> Edit -> Select All -> Tools 
-> Export


In the new micro: Tools -> Address Book -> Tools -> Import

With some difficulty, I discovered that in order to migrate the messages 
it was necessary to install the module ImportExportTools 
(https://freeshell.de//~kaosmos/mboximport-en.html), according to the 
Importing and exporting your mail site 
(http://kb.mozillazine.org/Thunderbird_:_FAQs_:_Migration#Specific_programs%20).


So I downloaded the "addonn" importexporttools-3.3.0-sm + tb.xpi from 
the Extensions page 
(https://addons.mozilla.org/pt-br/thunderbird/addon/importexporttools/).


After downloading click on the menu in Add-ins -> Install from a file, 
and I selected the file importexporttools-3.3.0-sm + tb.xpi.


And finally after installed I was able to transfer the files containing 
the messages with the command:


Right-click a folder in Icedove (old micro) and: Import / Export in mbox 
/ eml format -> Export folder -> Select the location to save the file 
and confirm


Right-click on a folder in Thunderbird (new micro) and: Import / export 
in mbox / eml format -> Import mbox file -> Import directly one or more 
mbox files -> Select the file containing the messages and confirm

Nothing I wrote was meant to imply Jessie was an inappropriate distro

Rather, Gnome3 is more demanding than your hardware was designed to

So, (optionally) removing gnome-desktop, and installing any other

Unless your 160GB disk installation unusually constrained your / 
partition
size, you can install multiple desktop environments, try each, then 
simply
continue using whichever turns out to be your favorite, optionally 
removing

the others.

https://wiki.debian.org/DesktopEnvironment lists Debian's primary desktop
options. If you've been a Gnome user in the past, Mate may turn out to be
your preference.

Alternatively, if switching to another distro is your wish, Edubuntu 
might

turn out to be an ideal choice.

If that isn't the case, adding nouveau.config=NvMSI=0 on kernel

Note that Gnome is arguably the most demanding among DEs from the

Hi David,

Thanks for your tip about sliding switch.

The tool rfkill was also very usefull.

Now I can see the local and remote devices.

The challenge now is to connect to cell phone (Nokia E71):

Following https://wiki.debian.org/BluetoothUser I tried gnome-bluetooth

I haven't used gftp in a long time. These days I just use the default

This just says that the kernel did not find the firmware for your Wifi
chip.  It should be installed in /lib/firmware, typically done by
installing the non-Free package "firmware-iwlwifi".

   

and does not enter the login screen.
 

Usually the failure to initialize the wifi card should not prevent the
proper startup of the GUI and its login screen, so you have two problems

Brazilian portuguese keyboard and accented characters (á, ç, ã)

[Markos]

Hi

I just installed Jessie in an IBM ThinkPad X60.

When I select the Keyboard "en" the keys work properly but can not 
generate non-English characters or accented characters, such as ç, ã  or á.


At another laptop (ThinkPad Z61) I type:

' + c -> ç
' + a -> á
~ + a -> ã
...

How to configure the IBM ThinkPad X60 keyboard to do the same?

Thanks,

Re: Brazilian portuguese keyboard and accented characters (á, ç, ã) (Solved)

[Markos]

Hi Michael,

After testing several input sources I found that the best would be:

Alternative international USA. (alt-intl)

But ccedilla "ç" was not working.

Searching on "The Debian Administrator's Handbook" 
(https://debian-handbook.info/) I found in section "8.1.2 Configuring 
the Keyboard":


"Until Debian Lenny, the keyboard layout was controlled by two different 
systems: for the console, console-tools / console-data; for graphical 
environments, keyboard-configuration.


Since Squeeze, These two systems have been unified and 
keyboard-configuration controls the keyboard layout in both console and 
graphical mode. The dpkg-reconfigure keyboard-configuration command can 
be used at any time to reset the keyboard layout.


The questions are relevant to the keyboard physical layout (a standard 
PC keyboard in the US will be the "Generic 104 key"), then the layout to 
choose (Generally "US"), And then the position of the AltGr key (right 
Alt ).


Finally comes the question of the key to use for the "Compose key", 
Which allows for entering special characters by combining keystrokes. 
Type successively Compose ' e and produce an e-acute ("é"). All These 
combinations are described in the 
/usr/share/X11/locale/en_US.UTF-8/Compose file (or another file, 
determined according to the current locale indicated by 
/usr/share/X11/locale/compose.dir).


I had to enable the "compose key" with the following:

settings (configurações) -> keyboard (teclado) -> shortcuts (atalhos) -> 
typing (digitação) -> composition key (tecla de composição) -> righ Alt 
(Alt direito)


And in file /usr/share/X11/locale/iso8859-1 I found:
  : "\347"ccedilla
  : "\347"ccedilla
  : "\347"ccedilla

So ccedilha "ç" could be typed with Alt + , + c or Alt + c + ,

I also found some info at https://wiki.debian.org/Keyboard

Thanks for your tip.
Markos

What output format do you want? For HTML, simply running a XSLT 
processor (such as the one in package xsltproc) against the stylesheet 
(contained in package docbook-xsl for Docbook 5 or docbook-xsl-ns for 
Docbook 5) is enough. See  the documentation for the packages for a 
list of available stylesheets.


For other formats I cannot help you much, but I believe the first step 
is similar: use a stylesheet to convert the docboock source to an 
intermediate format, which is then processed by specific tools to 
generate the final output.



Hi Eduardo,

I saw that there is a lot of information in the tutorial:
http://www.sagehill.net/docbookxsl/index.html

I already have many documents sources with which I've been using the 
script jw to output in html.


Could you possibly give me some tips on how to use the xlstproc in 
Debian Squeeze?


For example, I saw that there is a package:

xsltproc - XSLT 1.0 command line processor

I think that I should install this package: apt-get install xsltproc

What else?

And what changes I should do in the header of my source documents?

At the moment they are:

?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE article PUBLIC -//OASIS//DTD DocBook XML V4.1.2//EN
/usr/share/sgml/docbook/xml-dtd-4.1.2/docbookx.dtd

And what command I should run to generate the html files?

The man page has all the details, but it is pretty simple anyway.

Yes. And also the package with the XSL stylesheets, which, for Docbook 
4, is docbook-xsl.



And what changes I should do in the header of my source documents?


None. Unless you would want to update to a newer version, but that is 
not necessary. And it would need more changes than simply the header.



And what command I should run to generate the html files?


Again, man xsltproc has the details, but basically something like

xsltproc /usr/share/xml/docbook/stylesheet/docbook-xsl/xhtml/chunk.xsl 
file.xml


There are other stylesheets, such as for HTML 4, XHTML 1.1, and also 
stylesheets that output everything in a single html file. See the 
documentation under /usr/share/doc/docbook-xsl for more details.


Hi Eduardo,

I intend to read carefully the tutorials (Ex: www.sagehill.net/docbookxsl)
to better understand DocBook XSL but at the moment I'm needing to 
generate html documents quickly.


And your tips worked.

Thank you very much.

Re: Serial Port Problems

[Markos]

Dear Ethan,

Your scale has a DB9, DB25 or USB connector?

It is important to make sure that the cable you are using has the 
correct pinout.


Your scale has come with a cable from manufacturer or you set up the 
communication cable yourself?


The DB9 serial cable for communication use, in general, only 3 pins, Tx, 
Rx and Gnd. If your instrument follows the standard RS232.


Then you need to know what are the serial communication parameters that 
the scale are using (data bits, parity, stop bit, bps) to be able to 
configure your acquisition program correctly.


Some instruments send information over the serial port automatically as 
soon as they are turned on, others send after setting the instrument by 
typing some commands at the keyboard, and there are some instruments 
which send information only after receiving commands by the computer.


The manufacturer's manual should provide this information.

And finally use an acquisition program to verify that data is being 
received correctly to be processed.


I have some information about serial communication on these sites:

http://www.c2o.pro.br/automacao/x834.html
http://www.c2o.pro.br/automacao/x2467.html

Are in Portuguese. Use Google translator.

Any question, email-me,
Markos

Re: Building/Compiling game xonix without X11 for console only

[Markos]

Hi,

How to play this game?

Thanks,
Markos

Hi,

I like `xonix' quite a lot. This game is so fun!

But I prefer to play it from the console, rather than in an X window. 
The game originally written without X11 support. Here is man page 
xonix(6x):


The original xonix game has been seen somewhere on an old PC/XT  clone.
   This  is  a  reimplementation  from  scratch, done by Torsten 
Schoenitz
   starting the project on a Macintosh.  The X11 support has been  
written
   by Joerg Wunsch with the pleasant help by Alfredo Herrera 
Hernandez.


I tried this:

$ apt-get source xonix
$ cd ./xonix-1.4/
$ ln -s ./Makefile.std ./Makefile
$ #'cuz `make' looks for Makefile, without .std extention

This does not compile, since I did not run the following:
$ sudo apt-get build-dep xonix

And since I am not building for X11, I actually do not need (most) of 
those dependencies! So I am not installing them.


Question is:
In the Makefile.std, a MACRO called USE_X11 was defined. Which was 
also defined in xonix.h. I tried to fix Makefile.std into this:


#EXTRA_DEFINES=-DUSE_X11=0 -DXONIXDIR=\$(XONIXDIR)\ $(CUTE)
EXTRA_DEFINES=-DXONIXDIR=\$(XONIXDIR)\

And then run `make'.
Here is the output:

make: *** No rule to make target `/usr/X11R6/include/X11/Xos.h', 
needed by `xonix.o'.  Stop.



Or I tried building directly calling gcc:
gcc -UUSE_X11 ./xonix.c
In file included from ./xonix.c:42:0:
./xonix.h:171:1: error: unknown type name ‘Boolean’
 extern Boolean  gQuit,  /* Wenn gQuit auf true 
gesetzt  */

 ^

In the code, it was said that the X11/Xos.h provides Boolean.

So, how to build this little piece of game without X11 support?

Debian does provide freebasic for oldstable only, but in addition for

Re: Photovoltaic inverter monitoring or logging software

[Markos]

Dear Bret,

If the instrument has a RS232 interface probably it sends information in 
ASCII format.


It would be important to see equipment manual to know how this 
communication works.


Do you have a cable for conection of the instrument with a computer?

In some instruments you set, by the keyboardthe the sending of data over 
serial in a unidirectional way, ie, the instrument only sends data but 
does not receive commands.


Other instruments offer the possibility bidirectional communication, 
receives commands and sends information.


Send more information about this instrument, link to download the 
manual, and we'll see if we can help you.

I am seeking software that will interface with Rewatt inverters, which

Dear Scot and Stephen,

I am using this model of modem:

http://www.4glterouter.de/huawei-b890-4g-lte-smart-hub.html
 

Thanks - yes it's the chipset I was expecting.

   

I just tested on another machine and the modem supplied the IP to my
laptop via wireless and IP to a computer (with 1 NIC) via ethernet
without problem.
 

Yes.

   

Tomorrow I'll change the network card (of the machine with 2 NICs) and
test again to see if the problem is the network card.
 


OK - I misunderstood - I didn't realise you had a second card installed
and assumed you'd just noticed the USB modem cable is seen as a NIC, or
that networkmanager had autoconfigured it for you (it should, if you
have a recent version of usb-modeswitch installed).
You don't need the 2nd network card unless you want to duplicate the
routing functionality build into your modem/hub/router. Just connect the
modem to that computer with the USB cable. Make sure you have
usb_modeswitch installed and add the extra line I suggest (the gateway
stanza).

The modem should then be seen as /dev/eth1 by Debian and will be used as
the gateway for your internet. You'll find that resolv.conf will
automagically use the modem as the nameserver .i.e. /etc/resolv.conf
will contain:-
nameserver 192.18.1.1

You don't need to add netmask and broadcast stanzas to
/etc/network/interfaces, you do need to change auto to hot-plug for the
modem (yes it's USB but the system will see it as an eth device).

Any other devices you connect to the modem should automagically (via
DHCP) do the same - and by default will all be able to communicate with
each other.

NOTE: the route output I quoted (in the previous post) is from a box
connected to a similar Huwaei modem in the same situation.

/etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
 address 192.168.0.6
 netmask 255.255.255.0
 gateway 192.168.1.1
 # dns-* options are implemented by the resolvconf package, if
installed

allow-hotplug eth1
iface eth1 inet dhcp
 # you could make this static, but more typing would be involved


NOTE: network and broadcast stanzas are optional

   

Thanks for your attention,
Markos

Dear Scott Ferguson, Stephen Powell, Dan Purgert, Andrei POPESCU, Pascal 
Hambourg, Rod James Bio and Rob Owens,


Thanks for your comments.

As I said, I tested the modem at home, and it worked well.

I imagine that the initial problem was related to the network adapter.

The next day I changed the network card and realized the following:

When I changed the network card the system started to assign the address 
to eth2 the new card and the modem sent the IP address for this card (eth2).


Despite that the /etc/network/interfaces is:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0

auto eth1
iface eth1 inet dhcp


Then I replace the second NIC by another one and again the system 
assigned the number eth3 for this new card.


And also the modem sent the IP number OK.

Every time I change the card the system increment the number to the 
interface: eth2, eth3 etc..


I searched on the Web

You *could* have things connected backwards. Also, you're missing some
configuration details for eth0.

You need to be bridging eth0 and eth1, I think.  It's been ages since I've set
up a PC as a router, because off-the-shelf ones are usually good enough at the
routing part (DHCP, DNS, etc can be offloaded, but that's easy, and doesn't
require 2 NICs).

He's using a Huawei B-890-53 4G modem/hub[1], and is trying to hook up a *nix
box to act as a router for other devices.


Really rough diagram (from my understanding of the OP) is as follows:

[b-890]---  [eth0] {missing config?} [eth1]---  other device(s).

Not really sure why he needs to do this, as the Huawei box has in integrated
DHCP server/router ... but something like this should work:


1. Set eth0 to have a static IP (e.g. 192.168.0.1)[2]
2. Install DHCP onto the *nix box.
3. Set the IP of eth1 to some other subnet[2] (192.168.1.0/24 or a class A or B
network -- 10.x.x.0/24 or 172.16.x.0/24).
4. Bind DHCP to eth1 (so it answers requests for internal devices)
5. Set up a route from eth1 to eth0, and vice versa.
6. Set up dnsmasq in iptables.
7. hook up internal switch, etc.


Now, the downside to this approach is that devices connected to the Wifi AP of
the Huawei device will not be able to communicate with the stuff behind the *nix
server.  An easier solution (IMO) would be something like the following:

1. Install DHCP server on the *nix box.
2. Set eth0 to a static IP address (e.g. 192.168.0.1).
3. Bind DHCP and DNS to eth0.
4. Connect eth0 on the Huawei device to eth0 of the *nix box.
5. Connect eth1 on the Huawei device to a switch (for the other computers).

A setup like this will then put all devices (wired and wireless) on the same
subnet so they can communicate without any issues.

Please note, this is really high level, and I'm probably forgetting some of the
finer details.

-Dan

[1]That's what they call it anyway.

[2] Something like this should work:

auto eth0
iface eth0 inet static
address 192.168.0.2
netmask 255.255.255.0
gateway 192.168.0.1
[dns-nameservers 208.67.222.222 208.67.220.220]-- these are openDNS, use your
ISP, some other DNS provider, or your internal nameservers if you'd like.


auto eth1
iface eth1 inet static
address 192.168.1.1
netmask 255.255.255.0
gateway 192.168.0.2

eth1 might be wrong, like I said, it's been ages.


   

Dear Dan,

Thanks for your attention.

Let me explain in more detail the situation .

I organized a small network with 6 machines all with static IP and 
centralized log server ( 192.168.0.1 ) with NIS .


This network don't has Internet access, only on weekends I use my mobile 
phone on the server ( 192.168.0.1 ) and through a connection ppp0 share 
the Internet access for other machines on the network .


lan eth0 192.168.0.1 ppp0 Internet

I described all steps of that network on my page (but are in Portuguese ) :

http://www.c2o.pro.br/inf/pimentel/x38.html

And I used iptables to control the network.

But recently bought a modem router :

http://www.4glterouter.de/huawei-b890-4g-lte-smart-hub.html

and today I did my first test with this modem .

I just installed another NIC (RTL8139) in the server (eth1) and replace 
the ppp0 to eth1 in the firewall script below .



I just did a test at home and the modem provided the IP for 2 ethernet 
connections without problems.


Tomorrow I'll change the network card of the server and see if the 
problem is on the network card.


Thanks for your attention,.

Best Regards,
Markos

Hello list,

nvidia-kernel-dkms

[I referred this wiki : https://wiki.debian.org/NvidiaGraphicsDrivers ]

I also created the Xorg.conf file as mentioned in the wiki. But when I
rebooted my system Xorg failed to start. So i figured that I am having
a GPU with optimus support and I do not need the Xorg.conf file but
instead I need the bumblebee package.

So I installed the bumblebee package.

Everything seem to work now except this:

Under system-Nvidia server settings when I open It i get a message:
You do not appear to be using the NVIDIA X driver.  Please edit your X
configuration file (just run `nvidia-xconfig` as root), and restart
the X server.

But there was already a post in bumblebee wiki which said:

Warning: If you choose to install bumblebee-nvidia and the dependent
nvidia driver packages, during postinst, you will see a debconf prompt
warning you that you need to create a xorg.conf file in order to use
the proprietary nvidia driver. This prompt only applies to non-Optimus
users, i.e. single Nvidia GPU systems. Do NOT allow debconf to create
a xorg.conf file, and do NOT run nvidia-xconfig! (This prompt always
appears when you install nvidia packages through the repositories, and
it currently does not detect Optimus/bumblebee users. See 735049 for a
brief explanation.) 

So I am pretty sure that I do not need to run that nvidia-xconfig command.

But I just want to make sure that I am running the nvidia driver
successfully. How can I do that?




   


You're not alone.

I have the same problem.

I have a new laptop with the GeForce GT 750M video card.

And yesterday I made several attempts to install the Nvidia driver, 
using packages from backports and the proprietary installer from Nvidia, 
it did not work.


The NVIDA-setting application always indicated he was not running the 
nvidia driver.


And besides the command:

bumblebeed service restart

Do not restart the program.

If you find a solution, please share with the list.

Wheezy NVidia driver for card GT 750M

Dear,

I just installed Wheezy 7.4 on a notebook with Nvidia video card 
GeForce GT 750M.


I searched the site:

https://wiki.debian.org/NvidiaGraphicsDrivers

And from what I've seen, the list of devices supported by the version 
304.88:


http://us.download.nvidia.com/XFree86/Linux-x86/304.88/README/supportedchips.html 



does not include the GT 750M model

Another option is to use the Nvidia proprietary installer available at:

http://www.nvidia.com/download/driverResults.aspx/72249/en-us

Version: 331.38
Release Date: 01/13/2014
Operating System: Linux 32-bit

Is there a newer Debian package that includes the GT 750M card?

How to find?

Thanks for any tip.

If you want smooth Debian-style installation, you can use the version
that is backported (319.82) - it lists these models as supported in its
documentation:

 GeForce GT 750M   0x0FE4 D
 GeForce GT 750M   0x0FE9 D

It is available through backports:

https://packages.debian.org/wheezy-backports/nvidia-driver

I am using it myself (though with a 650Ti), and it works flawlessly.

Now one more question .

I am confused about which packages should I install .

The site :

https://wiki.debian.org/NvidiaGraphicsDrivers

recommended to install the linux -headers and kernel module packages :

linux -headers- $ aptitude- r install ( uname - r | sed ' s , [ ^ - ] *

then install the nvidia-glx package and create the file /

Section Device 
Identifier  My GPU 
Driver  nvidia

But on other sites , for example , at:

http://www.fandigital.com/2012/05/install-nvidia-in-debian.html

recommended to install the packages:

apt- get install nvidia-glx nvidia-kernel-dkms nvidia-xconfig 
nvidia-settings


And do not mention the installation of linux-headers- ...

And in other sites :

http://gnutwoall.wordpress.com/2013/07/29/nvidia-no-debian-wheezy-mais-uma-vez/

recommends :

# apt- get install build-essential dkms linux-headers-` uname -r`

and then :

# apt- get install nvidia-glx nvidia-installer-cleanup libgl-nvidia-glx 
nvidia-alternative libxvmcnvidia1 nvidia-kernel-dkms nvidia-support
nvidia-vdpau-driver xserver-xorg-video-nvidia nvidia-settings 
nvidia-xconfig-table utils


I am confused with so much information.

Please some tips about the packages for card GT 750M.

Thank you for your attention .

Where are the CD 9, 10 ... for Debian Wheezy?

[Markos]

Dear all,

Please, where are the  iso CD (i386) for Debian Wheezy beyond the CD 8?

The link for 7.4 does not exist:
http://cdimage.debian.org/debian-cd/7.4.0/i386/iso-cd/

And the link for 7.3:
http://cdimage.debian.org/debian-cd/7.3.0/i386/iso-cd/

I found only the links until the CD 8.

But the list of md5sum indicates that there are 68 CDs
http://cdimage.debian.org/debian-cd/7.3.0/i386/iso-cd/MD5SUMS

Any tips?
Thank you,
Markos

How to use de update CDs?

[Markos]

Hi All,

I'm planning to download the CDs :

But I don't know how to use the CDs Update.
debian-update-7.3.0-i386-CD ...

Please, how do I use these CDs?
 debian-update-7.3.0-i386-CD-1.iso
 debian-update-7.3.0-i386-CD-2.iso
 debian-update-7.3.0-i386-CD-3.iso

Since those CDs are not usually needed, they are not hosted as HTTP/FTP
downloads. You can however use Jigdo to download them. See the
instructions at https://www.debian.org/CD/jigdo-cd/
   

Marius,

Thanks for the tip.

I didn't know the jigdo tool.

Indeed, it's not the method I asked about.

 Im afraid that info is lost. Unless you have more of those

 The retention period of that log can be changed in vim

I think I should change the option rotate in /etc/logrotate.conf

/var/log/wtmp {

create 0664 root utmp
rotate 1 -- change this value to 12 to keep log files for 12

...

But I have another doubt. This log only the login at this machine. But
how to log the autentication of other machines at the NIS server?

How keep the login history of NIS clients at only one file at NIS
server?

Is there any way to do that?

My idea is to use this strategy as a alternative to generate an
attendance list of students in classroom.

 hope it helps

How get login history on NIS server during all months?

[Markos]

Hello,

We have a NIS server in a small network (6 PCs), and I need to get
informations about the login history of all users on NIS server during
all months.

The command last (on server) shows only the login of current month, on
the server.

The command last -f /var/log/wtmp.1 shows only the month before.

Is there any way to get this information?

 That tells me that one of two things are the problem.  Either 1) your
 /etc/nsswitch.conf file is incorrect.  Look there and make sure it has
 these lines:
 
   passwd: files nis
   group:  files nis
   shadow: files nis
 
   hosts:  files dns
 
 Note: The use of 'shadow' depends upon the setting of MERGE_PASSWD.
 Note: The hosts setting probably isn't the problem but can be if
 people set it to nis.
 
 If those three file maps are set to files first then nis then the
 local files will always override the network nis/yp account setting.
 
 Or possibly 2) you have your nis/yp token + above the locally added
 accounts when it should be below the locally added accounts in the
 /etc/passwd file.  When using compat and the + token then the
 account priority is in first one seen from top to bottom.  (Except
 when using the 'nscd' package which randomizes it through a hash.  I
 always remove it.)
 
 I strongly recommend using files nis instead of the old traditional
 compat method that uses the + token  It just makes things so much
 simpler.
 
  How do I remove the accounts root and student1 only on the NIS
  database on the server?
 
 You should never be using root from the nis/yp remote network
 accounts!  Always use the local root login account.  But I think you
 are doing so and just don't realize it.  Because I think if you were
 to try to use root account info from the network then you would have a
 bootstrapping problem because the system would not be able to
 bootstrap itself going.  See also the MINUID variable which scrapes
 the presence of the root and other system acounts out of the master
 copy of the file before giving it to clients.
 
 Do you care about those logins on the server machine?
 
 If you set up nis/yp to use /etc/passwd as the master copy of the file
 then simply remove the student1 account from it.  (Do not remove the
 root account from it!)
 
 Of course if /etc/passwd is both the local file and the nis/yp map
 file then that will also remove the local login capability from
 student1 too.  But usually that is fine and normal.  I never allow
 random user logins on the nis/yp and nfs server master machine.  It
 ensures that the machine is kept dedicated to nis/yp and nfs only
 which is a good thing.
 
  I want to login as root or student1 on the client machines with the
  server off.
 
 Then they need to be configured as local users on the machine.  Local
 users mean that they are in the local /etc/passwd, /etc/group,
 /etc/shadow files as a local user.  It means that if compat and + is
 used then they must appear above that token.
 
  Is there any command like delusernis for Debian Squeeze?
 
 If /etc/passwd is used as the master copy of the file then you may use
 the 'deluser' command just like any normal user.
 
   man deluser
 
 Or simply edit the file and make those deletions manually.  It is just
 a text file.  There isn't anything magical or difficult about it.
 
 I have been saying if /etc/passwd is used as the master copy for
 nis/yp because that is configurable for nis/yp.  See the YPSRCDIR
 variable.  I personally never use /etc there but insteal always keep
 nis/yp account data in /var/ypfiles/passwd and so forth for the group
 and shadow files.  That way the machine can serve accounts without
 giving those accounts access to the server machine itself.  To me that
 makes the most sense.
 
 But that means that those files need to be edited by some method other
 than adduser and deluser since those use /etc.  That is okay.  I
 simply edit /var/ypfiles/passwd and so forth manually.  I use scripts
 with semaphore lockfiles.  Or I know that it is only myself editing
 those files and simply edit them with my favorite editor.
 
 But setting up a separate /var/ypfiles takes someone who knows they
 want to set that up.  It is configurable.  In many years of looking at
 various large corporations I have always seen it set up that way at
 any larger site.  For me that is the normal thing to do.  But if you
 haven't known that then the simple default is to use the /etc/passwd
 file.  But there isn't a way for me to know without asking and saying
 about it both ways.

In my case it is set to false
MERGE_PASSWD=false

I think it is better to leave it as is?

No. Only local.

How to log at a NIS client with local user?

[Markos]

Dear,

For the first time, I configured a NIS service on a small network.

Now I observed that if the NIS server is turned off, the NIS client can
not load the login screen. So I'm not able to log even as local user in
client nis machine.

What can I do to login as local user in a client nis machine when the
nis server is off?

Is it possible?

Thanks,
Markos

 2. Change /etc/network/interfaces 'allow-hotplug eth0' to 'auto eth0'.
 

The file /etc/network/interfaces on server is:

auto lo
iface lo inet loopback

auto eth0

  netmask 255.255.255.0

The file /etc/network/interfaces on client is:

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
  address 192.168.0.2
  netmask 255.255.255.0
  gateway 192.168.0.1


 3. Remove bg from the /etc/fstab options list.
 
 Additionally since then I wonder if you are booting with legacy boot
 order or if you are using the new parallel boot order.  Do you have
 this file:
 
   ls -ldog /etc/init.d/.legacy-bootordering
 

There is no such file neither on the client nor the server.


 And that made me wonder if there are additional files left behind as
 lint from previous upgrades in /etc/init.d that may be causing
 problems keeping it using legacy boot ordering.
 
   dpkg -l | grep ^rc
 
No return of this command.

This is a new installation (CD 1 and 2) both the client and the server.

 Are there packages installed, removed, but not purged that would
 contain /etc/init.d files?  If you do then it is probably time to do
 housecleaning.
 
 Bob

I'm thinking don't insist too much about it and include the file /etc/
rc.local of the client the command:

mount  -t nfs 192.168.0.1:/home /home/home_servidor

It is not an elegant solution, but it solves the problem for now.

Is there any difference in operation between the mounting of a partition
using the /etc/fstab and /etc/rc.local?

Thank you very much for your attention.

How to remove users only on NIS database?

[Markos]

Dear,

I have a small network with 6 machines running Debian Squeeze.

When installing the machines I created only the root account and a user
student1 in all machines on the network.

Then I installed a NIS Service on a machine (server), to centralize
logging of new users.

But now, I realized that if I shut down the server I can no longer login
as root, or student1, on the client machines.

How do I remove the accounts root and student1 only on the NIS
database on the server?

I want to login as root or student1 on the client machines with the
server off.

Is there any command like delusernis for Debian Squeeze?

Thanks for any help,
Markos

Dear,

I just checked the configuration file /etc/fstab on the client machine
and the server IP address is correct. 192.168.0.1

When writing the message I copied and pasted the IP address of the site
that I used as a reference and I forgot to check.

Sorry for the mistake.

Do you have any other suggestions?

Thanks for your attention,
Markos

 Okay.  Sounds good.
 
  The NIS service seems to be working
 
 Good.
 
  but NFS don't mounts the /home partition on the clients during boot.
 
 Focus only on the NFS part of the debugging.  Do not be distracted by
 the NIS/yp part.  They may work together in supporting roles but they
 are completely independent subsystems.
 

This is important information for me. I had no experience with NIS or
NFS and I was very confused about the relationship between the two
services

  But I can manually mount the /home partition on the clients with the
  command:
  
  mount 192.168.0.1:/home /home
 
 Good.
 
  I found the strange message in dmesg:
  
  svc: failed to register lockdv1 RPC service (errno 97)
 
 I am unfamiliar with that error and searching didn't turn up anything
 for certain either.
 
  How can I discover what is wrong?
 
 Almost always the information will be logged in /var/log/syslog and
 hopefully there will be clues there.  Start by looking there.
 

I only have access to computers on weekends.
The next weekend I'll check the error messages in syslog and I'll post
what I find.

 Thanks for including much information.  However the file I am
 interested in is /etc/network/interfaces.  The new device way is to
 support a hotpluggable event driven system.  That may be incompatible
 with the traditional nfs mounted home directory environment.
 Specifically you probably have this:
 
   allow-hotplug eth0
 
 Try changing that line to:
 
   auto eth0
 
 Then instead of using the new event driven control flow at boot time
 it will use the old legacy start-at-boot time control flow.  This will
 also re-enable use of 'service networking restart' as one of the
 working ways to restart the network.
 


I am making available information about mounting of this small network
on the site 
http://www.c2o.pro.br/inf/pimentel/x30.html 
but unfortunately the content is only in Portuguese.

The file /etc/network/interfaces of the server is:

# The loopback network interface
it self
inet loopback iface it

auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0

And the client is:

# The loopback network interface
it self
inet loopback iface it

auto eth0
iface eth0 inet static
address 192.168.0.2
netmask 255.255.255.0
gateway 192.168.0.1


 If the problem isolates itself to just that change then please file a
 bug with the details.  I happen to be running with 'auto' for other
 reasons and nis/yp with nfs mounted home direcotries is working fine
 for me.
 
  In file /etc/fstab I included the line
  192.168.10.101:/home /home nfs 
  rw,bg,tcp,rsize=32768,wsize=32768,hard,nointr,nolock,noac,timeo=600,user,auto
   0 0
 
 Secondly I would test it without the 'bg' option in the /etc/fstab.
 This is a philosophical issue but if the machine needs /home to be
 useful then I believe it should wait for it to be available before
 presenting a login to a user.  Otherwise the user will be confused
 that they can log in but don't have a home directory.
 

I copied these options from a site. I was thinking to simplify and
replace with just defaults

192.168.10.101:/home /home nfs defaults 0 0

What do you think about?

  echo +  /etc/passwd
  echo +  /etc/group
  echo +  /etc/shadow
  echo +  /etc/gshadow
 
 I know that is the legacy way but personally these days I prefer to
 use this configuration instead.  It is simpler.
 
 In /etc/nsswitch.conf file:
 
   passwd: files nis
   group:  files nis
   shadow: files nis
 

Ok.

But what about the files /etc/passwd ... /etc/gshadow. Should remove the
+ at the end of these files?

 Bob

After some time just reading manuals and mailing lists, I get confused
with so much information and a tip from someone more experienced is very
important.

Thank you verymuch for your attention.

Help with NIS+NFS in Squeeze

[Markos]

Dear,

Please, I'm confused!

I'm trying to configure the services NIS+NFS in a small network (7 PCs),
all running Squeeze.

The NIS service seems to be working but NFS don't mounts the /home
partition on the clients during boot.

But I can manually mount the /home partition on the clients with the
command:

mount 192.168.0.1:/home /home

I found the strange message in dmesg:

svc: failed to register lockdv1 RPC service (errno 97)

How can I discover what is wrong?

Thanks for any help.
Markos
mar...@c2o.pro.br



PS: I followed the steps below to configure the NFS (Server):

apt-get install nfs-kernel-server

In file /etc/exports I included the line

/home/ 192.168.0.0/255.255.255.0(rw,sync,no_root_squash)

And started the nfs server with the command:

/etc/init.d/nfs-kernel-server start



And NFS client:

apt-get install nfs-common

In file /etc/fstab I included the line

192.168.10.101:/home  /home nfs
rw,bg,tcp,rsize=32768,wsize=32768,hard,nointr,nolock,noac,timeo=600,user,auto  
0   0

-

And the followed steps to configure the NIS (Server):

apt-get install portmap 

apt-get install nis 

In /etc/hosts

192.168.0.1servidor.pimentel.eduservidor

In /etc/defaultdomain

pimentel.edu

In /etc/ypserv.securenets

255.255.255.0 192.168.0.0

In /etc/default/nis

NISSERVER=master

NISCLIENT=false


And the command

/etc/init.d/nis stop
/etc/init.d/nis start

And the command

/usr/lib/yp/ypinit -m

servidor and CTRL+D

In the file /etc/ypserv.conf I included

dns: no
files: 30
slp: no
xfr_check_port: yes

In the file /etc/yp.conf I included

ypserver 192.168.0.1

Edited /var/yp/Makefile

MERGE_PASSWD=false
MERGE_GROUP=false

And after create new users run make at /var/yp



And the followed steps to configure the NIS (Client):

apt-get install portmap 
apt-get install nis

In file /etc/defaultdomain

pimentel.edu

In file /etc/yp.conf I included

ypserver 192.168.0.1

Then the commands

echo +  /etc/passwd
echo +  /etc/group
echo +  /etc/shadow
echo +  /etc/gshadow

 Is there ANY new files under /dev/ after plugging it in?
 IOW, why does it have to be /dev/ttyUSB ?
 

I found at http://blog.gmane.org/gmane.linux.irda.general/month=20070101

A message whith the same description of my converter and the response
informs that should be created, for this converter, a device /dev/ttyUSB

Manufaturer: ARKMICRO
Vendor Id: 18ec
Product Id: 3118
...
...The ARK3116 USB-to-serial adapter is supported by the kernel (at least with
the latest 2.6 ones), so all you need to do is compile the ARK3116 driver,
compile irtty-sir as well, and you're basically done: irattach /dev/ttyUSB0
should do the trick...

Also at http://ubuntuforums.org/archive/index.php/t-1962929.html

A message show that this converter creates a /dev/ttyUSB
...
kernel: [ 375.720348] usb 3-2: ark3116 converter now attached to ttyUSB0
...

The desktop which with I intend to use this converter is being used in
the laboratory for data acquisition and running Lenny. 

Because that will be difficult to update the kernel or distribution (eg
Squeeze) so I'll try to download the driver ark3116.c, edit the source
code, including the VendorID and Productid, then recompile and load.

I believe it will be a less risky procedure. 

I was in doubt how to do that but I found some information on the links

http://www.linuxquestions.org/questions/showthread.php?p=2184457)

http://avr.auctionant.de/ark3116_linux_driver/index.html

I hope that works

Driver ARK3116 don't create /dev/ttyUSB

i searched on internet and the appropriate driver should be ark3116 but

How can I make this driver recognize this interface to create the device
(/dev/ttyUSB)

Re: Need help recovering hard drive

[Markos]

Dear Dennis,

I found at http://andrew.daviel.org/XP-disk-recovery.html, an
interesting strategy to use Linux to recover data from a hard drive with
NTFS system.

Perhaps the same strategy could be used for a HD with Linux (using dd)

...
dd if=/dev/sda1 of=sdb1  # aborted
dd if=/dev/sda1 of=sdb1a skip=2035000

I then made a file to fill the gap, and joined the pieces together. I
could then mount the resulting file loopback: 

dd if=/dev/zero count=704 of=zeroes
cat sdb1 zeroes sdb1a  XP0
mount -t ntfs -o ro,loop=/dev/loop1 XP0 /mnt/test
...

 One of my hard drives quit working, and as luck would have 
 it, just before the scheduled backup! So I need to recover 
 some info that has been updated/added since the last backup.
 
 First, is there any thing I can do to get the system to 
 mount that drive even with errors? As it is right now I get 
 error messages at boot time and the drive isn't recognized. 
 Apparently doesn't make any difference whether the drive is 
 on controller 0 or 1 or is master or slave.
 
 Second, is there any program that I can use to get data of 
 off that drive?
 
 TIA for any help!
 Dennis

Re: Πρόβλημα με ήχο σε Debian testing xfce , μετα απο upgrade

Παρότι δεν μπορώ να καταλάβω τι έκανε το σύστημα μου να μην έχει ήχο έτσι
ξαφνικά.Και για ποιό λόγο εξαφανιζόταν η κάρτα ήχου και εμφανιζόταν ξανά
μετα απο επανεκίνηση.
Με μια δοκιμή για επανεκίνηση του alsa μου έδινε κάποια errors.
Η λύση ήταν οτι σε κάποια entries στο /etc/modprobe.d/alsa-base.conf που
είχα βάλει για παλιότερο θέμα με τον ήχο , έλειπε το σήμα tης δίεσης (#) .
Εφόσον γίνει η αλλαγή , έκανα reboot και επανεκίνηση το alsa.O ήχος μετά
δούλευε.

Μέμο , όπως είπα και στο προηγούμενο mail ο user μου είναι μέλος στο audio
group.Εκανα και paste to output τις εντολής group σαν user.Πρίν την
αναβάθμιση είμουν στην testing.Το upgrade που έκανα ήταν ένα καθημερινό
update με αναβαθμίσης πακέτων και στέλνω και το log με τα πακέτα που
αναβαθμίστηκαν : http://paste.debian.net/185581/.
H κάρτα είναι 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family)
HD Audio Controller (rev 03).
Το σύστημα ήταν εντάξει μέχρι το upgrade.Μετά το reboot που μου ζήτησε
χάθηκε ο ήχος.
Ευχαριστώ για τον χρόνο σου.
