VLC is a sturdy, capable player that can run nearly any file, CD, disk, or DVD without issues. It can even play broken and fragmented files.

Vlc Player For Mac

Media on demand

Watch videos, listen to music, and stream your webcam with ease in this powerful multimedia program that’s just a download away.

VLC is one of the most popular players out there, and for good reason. It can run almost any media file available. There are a variety of video and sound file types in the world. Having one program to run all of them makes your life easier, and putting in your favorite album is a breeze. It’s easy to download and set it up. Once you get it going, you’re ready to run any media type you encounter.

VLC can also run DVDs and CDs, which is great. The only catch with a DVD is that you won’t be able to record any video footage from within the media player. But VLC still boasts high system compatibility as it will run on almost any computer, no matter how dated it is.

There are a couple of issues with VLC, one of which is the interface; it’s not particular attractive. In fact, it looks like something from the early 2000s. However, this doesn’t mean it’s complicated or painful to use. Aside from the visuals, you’ll notice that the software can become buggy or even crash at random times. This is usually caused by RAM-related issues, though a problem like this does imply a memory leak in the software.

With the many powerful and free programs out there, you need to be careful that you aren’t installing adware or spyware as an extra feature. Fortunately, VLC doesn’t come with any of those; it’s entirely ad-free and contains no malicious software.

Where can you run this program?

It’s available for the latest versions of Windows, Mac OS, Android, IOS and Linux.

Is there a better alternative?

No, VLC is a compelling media player. But if you find the user interface unpleasant, you can look at alternatives such as Eltima. Both software compete to be the best media players.

Our take

VLC is packed full of features and capability, but its instability presents some issues. In the face the expansion of QuickTime’s capabilities, users of newer versions of Mac OSX might find VLC to be a bit redundant. If you’re on an older version, however, VLC could be for you.

Should you download it?

Yes, if you’re looking for a new way to experience multimedia content, DVDs or CDs. It can read almost any video or sound file you’ll want to play.

Control Your Laptop with an Android Phone using Python, Twisted, and Django

Introduction

It is pretty enjoyable to put forth your Android or Python programming abilities. Recently, I just got an idea to use my laptop with my Android phone. Just Think: the remote laptop access will allow you to stop and play music, manage programming tasks or downloads, and so forth. You can do this by directly sending messages from your Android device. Nice, isn’t it?

Before you start reading this post, you must remember that it is a pet project, in its starting levels—yet the main platform is present. By using some conventional tools and techniques, I was proficient to setup my phone to manage laptop using Python mediator.

However: it is an open-source project. You can have a look at the server and client codes.

Tool Belt of Remote Laptop Access: Twisted, Python, Amarok and Django

There are diverse technologies involved in this project. You might be familiar with some; some technologies are particular to the project at hand:

Twisted: An exceptional project-driven structure particularly designed for the network hackers.

Python 2.7.

Amarok: It is a D-BUS controllable media player. You can select any other media player like VLC and Clementine that support MPRIS, if you are familiar with their messaging settings. I have selected Amarok because it came up with KDE distribution. Moreover, it’s configuration is easy and quick.

Django: I have used v1.4. Thus, you will need to change the place of some files if you have to run a previous version.

It is imperative to install Python For Android in your phone. The installation method is simple-also for Py3k.

Remote Amarok Web

Remote Amarok

At The High Level

At the high level, we will consider the laptop to be the server and Android phone, the client. I will explain the architecture of remote access in detail, yet the main project flow is mentioned below:

1.      The user will type a command into the mediator of Python.

2.      The command will be sent to Django.

3.      Now, Django will pass this command to Twisted.

4.      Twisted will analyze the command and then send a new one through D-Bus.

5.      D-Bus will then send the command to Amarok.

6.      Amarok will interact with the laptop, managing the pause/play of music.

We are going to explain it more.

Python For Android

One day, I had a glance at the mediators of Python that I could install and use on my phone (Droid 2). Shortly, I learned about the amazing SL4A package that was able to bring Python to life on the Android phone. It is a smart package to choose: you will need to click some buttons, and then you will almost get a Python environment on your Android device. This device can now run the Python code properly and access the Android API (I said almost because some things are still missing and the Android API is not readily available, yet for several use-cases, it is good enough).

If you want, you can develop Python distribution of your own to run on your phone. With its help, you can easily run any version of the mediator of your choice. In this method, you have to perform cross-compiling Python to run on ARM (the structure employed on Android devices). It is a bit tough, yet it is workable.

After setting up your mediator, you can do anything by linking Python to the Android API, comprising remote laptop controlling. For instance, you can:

•         Play/Pause videos and music

•         Set the ringtone of your choice

•         Read and send SMS.

•         Show the intuitive design

•         Check out the spinning dialogs and prompts.

•         Interconnect with third-party APIs across the web through urllib and diverse other libraries.

•         Interconnect with Bluetooth – It has to offer many opportunities. Like, I once used a lock-unlock app on my Android phone to control my laptop. (For example, locking up my laptop through Bluetooth when my Android device was close).

How Your Android Phone Controls Your Laptop?

The Framework

The composition of our project is below:

•         The client-side app developed on Twisted in case you need to check the server code devoid of running the Django app.

•         The server-side app designed on Django, which can read the commands from Android phone and then passes them to Twisted. As seen, Amarok is one particular application for a laptop that the server can interconnect with (specifically, to control videos and music). However, it is a full proof concept because the platform is adaptable.

•         The server-side app designed on Twisted “instance” which connects with the media player of the laptop through D-Bus, passing the commands when they come up from Django (presently, I prefer ‘mute’, ‘stop’, ‘pause’, ‘play’, ‘previous’, ‘next’). Why don’t you directly send messages from Django to Amarok? The non-blocking and project-driven features of Twisted can handle the big tasks.

Twisted is project-driven, exceptional, and adaptable. It contains deferred items, the callback system, and other methods to operate. I would recommend that you check it out: the amount of work that you will escape by making use of Twisted will be remarkable. For instance, it can assist boilerplate code for diverse protocols which incorporates HTTP, IRC, SSH, and so forth, devoid of dealing with the non-blocking tools like threads.

•         The Android code on client-side, transferred to your phone with the personalized URL to reach your app of Django. It is imperative to mention that this code specifically runs on Python 2.7+, which includes Py3k.

What is D-Bus?

I have mentioned D-Bus at diverse places, yet the time has come to explain it more. In general, D-Bus is a bus system which is used to send and receive messages. It allows the apps to communicate with one another (for example, on the Android phone and laptop) simply via designed messages.  

It contains two buses: the session bus that is used for the user-side things while the system bus for the system-side things. The special messages send to the system bus are like “Hello, I have connected a new printer, inform my D-Bus allowed apps that the new printed is online”, while the session bus will handle the standard IPC (Inter-Process Communication) between the apps.

In this project, we have used the session bus to interact with Amarok. It is one of those modern apps (among Linux environments, no less than) that assist this sort of messaging. The functions and commands its processes are well-organized. Any app with the support of D-Bus is easy to control and manage under this framework; there are limitless probabilities.

Background:

After setting up the framework, you can open the Android app and it will take you to the infinite loop from where you can read received messages, go for certain checks to process them, if usable, send them to the pre-mentioned URL (in other words, the Django application URL), which will operate the input. After that, the client of Android marks up the messages as read. The loop starts again till the message with the accurate details “exit-client” (fabulous, isn’t it?) is operated, in which the client exits.

On the server, the Django app chooses the command to be executed. It also analyzes if the command starts with valid instruction or not. If it does, it links to the server of Twisted (making use of the Telnetlib to link through telnet) and passes the command. In the end, the Twisted analyzes the input, modifies it into somewhat appropriate for Amarok. Allow Amarok to handle the rest! Lastly, your laptop will start responding to the send commands like pausing/playing music or videos.

When it comes to the “predefined URL”: if you need to control your laptop from a distant place, you will have to use a public URL. It is reachable across the web. Ensure that, presently, the code does not implement any security layer like SSL – similar advancements are practices for the person who reads, for now.

What Else Can You Do With This?

Till now, everything seems to be easy and straightforward, isn’t it? You may think: “Can it easily support the smart feature [X]?” Well, the answer to this question is: Yes! Nevertheless, you should have the know-how to interact with your laptop by using your Android phone. If you know, then you can easily add the code on server-side to do anything you want.

Before you get the know-how, you need to go through lengthy methods on your laptop remotely. Or else, if you have to capacity to match up with the technology, you can develop an interface amid your favorite electronic appliance and your laptop, managing it through SMS commands (“Make tea for me!” strikes instantly).  

What’s More

For now, I am going to play on with my new Android laptop controller, work on its features, fix up some bugs, and so forth. In case you are interested, I will be there for you to help! Just follow the instructions and email me at _________if you have questions.

Raspberry Pi 3 und IP-Kameras zur Videoüberwachung

Raspberry Pi 3 und IP-Kameras zur Videoüberwachung Hardware: Raspberry Pi 3, Digoo DG-WO2f, FosCam FI9826P, Digoo BB-M2 Das Angebote chinesischer Hersteller an billigen IP-Cams ist groß und obwohl man sich damit möglicherweise zum potentiellen Mitbetreiber eines Bot-Netzes macht und sich außerdem noch Zuschauer ins heimische Wohnzimmer holt, werden diese Cams massenhaft verkauft. Digoo z.B. wirft zum Beispiel seine Cloud-Cams mit minimalen Gewinnspannen auf den Markt, um mit dem dafür benötigten Cloudspeicher dem unbedarften Laien jeden Monat Geld aus der Tasche zu ziehen. Den Betrieb solcher Kameras sollte man nur über ein VLAN oder zumindest über NAT verbinden, da etliche dieser Billig-Cams bereits massenhaft gehackt wurden und über Backdoors verfügen. Zudem sind sie sehr geschwätzig und kontaktieren laufend Server, da sie als Cloudcams konzipiert wurden. Für dieses Projekt verwende ich diese billigen Kameras, da sie auch bei mir zuhause rumliegen...

Hinweis (10.10.2018)

In ZD-Net erschien am 9.10.2018 ein -> Artikel in ZDNet von Catalin Cimpanu, in dem er die Sicherheitsprobleme von Kameras des chinesischen Herstellers Hangzhou Xiongmai Technology Co., Ltd. beschreibt und auf die Anfälligkeit auch von DiGoo-Produkten hinweist. Insbesondere die Gefahr diese Kameras zum Werkzeug eines BotNetzes zu machen, sollte man beachten und beim Einsatz keine Verbindung zum Internet zulassen!

Streams der Kameras anzeigen

Als Erstes gilt es heraus zu finden, wie man an die Streams der Kameras kommt. Um die Kamerabilder auf den PC-Monitor zu bekommen, genügt bereits der Aufruf im Browser (z.B. Firefox mit dem AddOn Open in VLC media player und dem VLC-Player).

FosCam FI9826P

Für die FosCam FI9826P gibt man in die Adressleiste ein: [cce_bash]rtsp://<user>:<passwort>@<IP der Kamera>/videoMain [/cce_bash] Das AddOn öffnet den VLC Mediaplayer und videoMain liefert den Mainstream (hohe Auflösung). Für den Substream lautet der Aufruf [cce_bash]rtsp://<user>:<passwort>@<IP der Kamera>/videoSub [/cce_bash] Für unseren Zweck kann man auch den Link zum Snapshot verwenden: [cce_bash]http://<user>:<password>@<IP der Kamera>:<Port>/cgi-bin/CGIProxy.fcgi?cmd=snapPicture2&usr=<root>&pwd=<password>&; [/cce_bash]

Digoo DG-WO2f

Für die Digoo DG-WO2f lautet der Aufruf für den Main- und Sub-Stream mit den originalen Zugangsdaten: [cce_bash]rtsp://admin:dg20160404@<IP der Kamera>/onvif1 rtsp://admin:dg20160404@<IP der Kamera>/onvif2 [/cce_bash] Bei älteren Modellen ist das Passwort 20160404. Eine Verbindung über TELNET ist bei dieser Kamera mit dem User root und dem Passwort cxlinux möglich. Offene Ports dieser Kamera: Discovered open port 23/tcp Discovered open port 80/tcp Discovered open port 554/tcp Discovered open port 6670/tcp Discovered open port 7103/tcp Discovered open port 7101/tcp Discovered open port 5050/tcp Discovered open port 843/tcp Discovered open port 8001/tcp Discovered open port 3201/tcp

Digoo BB-M2

Bei diesem China-Billig-Modell erhält man Snapshots unter [cce_bash]http://<IP der Kamera>:81/snapshot.cgi?user=admin&pwd=admin& [/cce_bash] Hat man das Admin-Passwort oder den Port geändert, muss das angepasst werden. Streaming ist über http:// [cce_bash]http://<IP der Kamera>:81/videostream.cgi?loginuse=admin&loginpas=admin [/cce_bash] und rtsp:// möglich: [cce_bash]rtsp://<user>:<password>@<IP der Kamera>:10554/tcp/av0_0 rtsp://<user>:<password>@<IP der Kamera>:10554/tcp/av0_1 [/cce_bash]  

Streams mit mplayer anzeigen

Um einen Stream auf einem eigenen Display oder dem Display eines anderen Rechners anzuzeigen, eignet sich der mplayer hervorragend. Meist ist er in der Distribution schon enthalten oder man installiert ihn einfach nach. [cc_bash]:~ $ sudo apt-get install mplayer [/cc_bash] Von einer lokalen Konsole auf einer grafischen Benutzeroberfläche des Raspberry startet man die Kamera-Streams mit [cce_bash]:~$ mplayer <Streamingadresse der Kamera> [/cce_bash] und aus einer SSH-Sitzung mit [cce_bash]:~$ mplayer -vo fbdev <Streamingadresse der Kamera> [/cce_bash] Damit lassen sich komplette Überwachungsdisplays aufbauen, da man mit mplayer die Streams mehrer Kameras auf dem Bildschirm verteilt anzeigen kann. Ich komme später noch darauf zurück.

Raspberry vorbereiten

Dazu habe ich -> hier schon auf etliche Seiten verwiesen, die sich damit sehr fundiert mit der Installation beschäftigen. Um sich Arbeit zu sparen falls etwas schief geht, erstelle ich vor jeder größeren Installation ein Image der SD-Karte des Pi. Unter Windows verwende ich das USB-Image-Tool ( -> hier) . Unter Ubuntu reichen die Bordwerkzeuge aus. zunächst muss mit [cc_bash]:~$ df -h [/cc_bash] der Gerätenamen der SD-Karte festgestellt werden. Die SD-Karte erkennt man zum einen an der Größe und an den beiden Partitionen, von denen eine mit boot benannt ist. Um den gesamten Inhalt der SD-Karte zu sichern, benutz man den Gerätenamen (z.B. /dev/sdc). [cc_bash]:~$ dd if=/dev/sdc of=/path/images.img bs=4M [/cc_bash] Damit erhält man ein image, das genauso groß ist wie die SD-Karte. Wer Platz sparen will/muss, kann daraus gleich ein ZIP-File erstellen, in dem die leeren Bereiche der SD-Karte sehr gut komprimiert werden. [cce_bash]:~$ dd if=/dev/sdc bs=4M | gzip > /home/<user>/<filename>.gz [/cce_bash] Das Kopieren des Images aus einem gzip-File auf die SD-Karte erfolgt mit: [cce_bash]:~$ gunzip /home/<user>/<filename>.gz | sudo dd bs=4M of=/dev/sdc [/cce_bash]  

Motion detection auf Raspberry

Motion ist in allen mir bekannten Distributionen enthalten. [cc_bash]:~ $ sudo apt install motion [/cc_bash] Unter Debian benötigt man libav-tools, da ffmpeg warum auch immer damit ersetzt wurde. Die meisten anderen Distributionen verwenden weiterhin ffmpeg. [cc_bash]:~ $ sudo apt install libav-tools [/cc_bash] Die Konfiguration von motion befindet sich im Verzeichnis /etc/motion/ und besteht nach der Installation aus der Hauptkonfigurationsdatei motion.conf und aus Konfigurationsdateien camera_x.conf.  Für den Betrieb einer einzigen Kamera kann man alle Konfigurationsparameter in der motion.conf unterbringen. Will man mehrere Kameras betreiben, stehen nur die Parameter in der Datei motion.conf, die universell gelten. Die kameraspezifischen Angaben stehen für jede Kamera in einer eigenen Datei. Im Verzeichnis /etc/motion muss dann auch noch das Unterverzeichnis conf.d angelegt werden. [cc_bash]:~$ sudo mkdir /etc/motion/conf.d [/cc_bash] Die Aufnahmen speichere ich auf einer USB-Festplatte, die ich an den Raspberry angesteckt habe. Die wird deshalb auch unter /home/pi/<UUID der HDD> ins Dateisystem eingebunden und bei den Kameras als target_dir angegeben. Es ist sicher eine gute Idee, z.B. eine NAS zu mounten, aber zur Demonstration genügt mir diese Variante Ich habe eine Hauptkonfiguration motion.conf und für die beiden Kameras eigene Konfigurationen erstellt. Die originale Datei sollte man sich irgendwo sichern, da ich hier alle Kommentare zwecks Übersichtlichkeit entfernt habe.

TIPP

Wenn die Bilder später von motion immer wieder mit mehr oder weniger großen verwaschenen Streifen oder auch mit nach unten gezogenen vertikalen gleichfarbigen Streifen aufgezeichnet werden, dann glaubt man dem Hersteller zu sehr! Mit der VLC-Erweiterung für den Firefox oder irgendeinem anderen Programm die Informationen zur Bildgröße der Kamera suchen und in motion korrekt eintragen. Die Werte von height und width müssen auch durch 8 ohne Rest teilbar sein. In VLC findet man die Original-Bildgröße des Streams im Menü Werkzeuge -> Codec-Informationen und kann mit den aufgezeichneten Bildern gegenprüfen.

En esta página oficial de Xiaoyi tenemos las intrucciones para instalar otro firmware en la Xiaoyi Ant Cam:

- http://xiaoyi.querex.be/instructions/

Otros enlaces para aprender más sobre la cámara:

Diferentes versiones de firmwares -> http://xiaoyi.querex.be/firmwares

A pregunta de un usuario se explica cómo cambiar la zona horaria:

Andy 9/12/2016 | 9:56

1.8.6.1b work very well. Those in GMT+8 timezone, just change “-8mytz=UTC+8” in the equip_test.sh with windows notepad and you are done. In case you already flashed it, just reset and flash it again. The equip_test.sh file will only work once its reset.

A pregunta de un usuario también descubrimos cómo utilizar una cámara que nos dice que sólo se puede usar en China (el famoso “This camera can only be used in China”):

Kheang 24/08/2016 | 10:15                                                    

My yi camera home can not be use within china ??

admin 24/08/2016 | 10:18

Kheang, please try to download the chinese version of the”YiCamera” app by using a chinese apple id / play store account. If you don’t have one, create a second apple id / play store account for this region. This should solve your problem.

Veamos cómo instalar otro firmware y cosas sobre el RTSP, zona horaria...: (instrucciones sacadas de http://xiaoyi.querex.be/instructions/)

Instructions: How to flash another firmware

Note: flash firmware is at your own risk!

– Download a firmware version

– Turn off the camera (unplug USB)

– Remove micro SD card

– Power on (inset USB) and long press reset button

– Turn off the camera again

– Put the “home” firmware file on SD card (with a PC / laptop)

– Insert micro SD card an power on the camera again

– Wait around 5 min and try to connect with the smartphone app

– Check your cam it’s IP address in the router DHCP list

Modified firmware with additional features

To use the additional features, you need to flash a modified firmware version. You can download them on the firmware page. Flash instructions are quite the same as above, but for some versions you need to copy multiple files instead of only the home file.

RTSP url’s: Main stream: rtsp://ipaddress:554/ch0_0.h264 Minor stream: rtsp://ipaddress:554/ch0_1.h264 Audio stream: rtsp://ipaddress:554/ch0_3.h264 (Note: you can use VLC to test the RTSP stream)

Timezone: Edit the script “equip_test.sh” in a text editor. Modify the “my_tz=GMT+5” value, this is not the Green Mean Time. Seems the script developer uses GMT as “Chinese timezone”. You need to use the time difference between the Chinese and your own timezone as offset. Examples: – Belgium summer time (normally GMT+1) in this script GMT+6 – Belgium winter time (normally GMT+2) in this script GMT+7

FTP: User: root Password: 1234qwer Port: 21 (default FTP port)

Telnet: User: root Password: 1234qwer

HTTP: Via HTTP you get access to the SD card (as file website). Just use the IP address as website URL.

¿Qué hacer después de instalar CentOS 7?

La distribución CentOS Linux se deriva de los fuentes de Red Hat Enterprise Linux (RHEL). Al igual que RHEL, es una distribución que se destaca por su estabilidad, robustez, y simplicidad. Características deseables para los administradores de sistemas. Su estabilidad y robustez dan un buen nivel de confianza, al mismo tiempo que su administración es muy simple y ampliamente documentada. Aunque, estas características no se ponderan al momento de instalar GNU/Linux en una computadora personal, sino que se opta por tener un sistema no tan estable, pero con las versiones más recientes posibles de cada aplicación o paquete. Estabilidad y actualizaciones son conceptos divergentes, ya que la estabilidad de una aplicación se logra con años de testeo y depuración.

Ahora empecemos a preparar nuestro nuevo sistema.

Básico:

Como root ejecutamos

yum update && yum autoremove && yum install yum-plugin-priorities

yum install epel-release

Descargan estos .rpm y los instalan:

http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm http://linuxdownload.adobe.com/adobe-release/adobe-release-x86_64-1.0-1.noarch.rpm

Ahora os ubicáis en /etc/yum.repos.d y editan todos los repos que aparecen en dicho directorio añadiendo al final de cada repositorio las siguientes prioridades de uso:

priority=1   para CentOS-Base.repo, epel.repo priority=10  para nux-dextop.repo, adobe-linux-x86_64.repo

Ejemplo:

nano CentOS-Base.repo

# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.  You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 priority=1 #released updates [updates] name=CentOS-$releasever - Updates mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 priority=1 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 priority=1 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

Una vez estén modificados los repos mencionados seguimos:

yum install java-1.7.0-openjdk icedtea-web thunderbird firefox libreoffice libreoffice-langpack-es filezilla p7zip unzip zip gimp kernel-devel dkms telnet mc wget htop ntfs-3g yum install gstreamer-plugins-good gstreamer-plugins-bad gstreamer-plugins-ugly yum groupinstall "Development Tools" "Development Libraries" yum install vlc lm_sensors unrar foomatic sensors-detect

Puede que el comando yum groupinstall "Development Tools" "Development Libraries" no funcione, hay que utilizar:

yum groupinstall "Development Tools"

Testeando el Hardware

sensors-detect

Este comando nos permitira configurar el hardware de nuestro equipo:

(Pongo mi configuración)

$ [root@kozlov yum.repos.d]# sensors-detect # sensors-detect revision 3.4.0-4 (2016-06-01) # System: Dell Inc.

It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing.Some south bridges, CPUs or memory controllers contain embedded sensors. Do you want to scan for them? This is totally safe. (YES/no): YES Silicon Integrated Systems SIS5595...                       No VIA VT82C686 Integrated Sensors...                          No VIA VT8231 Integrated Sensors...                            No AMD K8 thermal sensors...                                   No AMD Family 10h thermal sensors...                           No AMD Family 11h thermal sensors...                           No AMD Family 12h and 14h thermal sensors...                   No AMD Family 15h thermal sensors...                           No AMD Family 16h thermal sensors...                           No AMD Family 15h power sensors...                             No AMD Family 16h power sensors...                             No Intel digital thermal sensor...                             Success!    (driver `coretemp') Intel AMB FB-DIMM thermal sensor...                         No Intel 5500/5520/X58 thermal sensor...                       No VIA C7 thermal sensor...                                    No VIA Nano thermal sensor...                                  NoSome Super I/O chips contain embedded sensors. We have to write to standard I/O ports to probe them. This is usually safe. Do you want to scan for Super I/O sensors? (YES/no): YES Probing for Super-I/O at 0x2e/0x2f Trying family `National Semiconductor/ITE'...               No Trying family `SMSC'...                                     Yes Found `SMSC SCH5514D-NS Super IO'                              (no hardware monitoring capabilities) Probing for Super-I/O at 0x4e/0x4f Trying family `National Semiconductor/ITE'...               No Trying family `SMSC'...                                     No Trying family `VIA/Winbond/Nuvoton/Fintek'...               No Trying family `ITE'...                                      NoSome systems (mainly servers) implement IPMI, a set of common interfaces through which system health data may be retrieved, amongst other things. We first try to get the information from SMBIOS. If we don't find it there, we have to read from arbitrary I/O ports to probe for such interfaces. This is normally safe. Do you want to scan for IPMI interfaces? (YES/no): YES Probing for `IPMI BMC KCS' at 0xca0...                      No Probing for `IPMI BMC SMIC' at 0xca8...                     NoSome hardware monitoring chips are accessible through the ISA I/O ports. We have to write to arbitrary I/O ports to probe them. This is usually safe though. Yes, you do have ISA I/O ports even if you do not have any ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES Probing for `National Semiconductor LM78' at 0x290...       No Probing for `National Semiconductor LM79' at 0x290...       No Probing for `Winbond W83781D' at 0x290...                   No Probing for `Winbond W83782D' at 0x290...                   NoLastly, we can probe the I2C/SMBus adapters for connected hardware monitoring devices. This is the most risky part, and while it works reasonably well on most systems, it has been reported to cause trouble on some systems. Do you want to probe the I2C/SMBus adapters now? (YES/no): YES Using driver `i2c-i801' for device 0000:00:1f.3: Intel Cougar Point (PCH) Module i2c-dev loaded successfully.Next adapter: Radeon i2c bit bus 0x90 (i2c-0) Do you want to scan it?

Just press ENTER to continue: Driver `coretemp':  * Chip `Intel digital thermal sensor' (confidence: 9)Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): no To load everything that is needed, add this to one of the system initialization scripts (e.g. /etc/rc.d/rc.local):#----cut here---- # Chip drivers modprobe coretemp /usr/bin/sensors -s #----cut here----You really should try these commands right now to make sure everything is working properly. Monitoring programs won't work until the needed modules are loaded.Unloading i2c-dev... OK
