Next steps after downloading the image

Instructions on how to write the downloaded image to your card can be found here:
http://elinux.org/RPi_Easy_SD_Card_Setup
The image is only utilizing 4GB of your card, even if you bought a bigger one. On a bigger card, you can make more space available to your root partition by running on the console of your booted RPi:

raspi-config

Select the option expand_rootfs. If you rather prefer to do this manually, one of the easiest ways is using GParted on Linux. Details can be found here:
http://elinux.org/RPi_Resize_Flash_Partitions#Manually_resizing_the_SD_card_using_a_GUI_on_Linux

1. Determine hostname / IP address

Once your RPi is booted, you need to know it’s hostname or IP address for ssh login or to open the web GUI. On Windows computers, you can just use the hostname raspbx to access your RPi.
SSH login:

ssh root@raspbx

Web GUI:

http://raspbx

On Macintosh, use raspbx.local instead:

ssh root@raspbx.local

Web GUI:

http://raspbx.local

In case this is not successful you can check your router’s DHCP client list, and search for the IP associated with the name raspbx.
If this is still not working out, you can always just connect an HDMI monitor and USB keyboard, log in to the console with user root, password raspberry, and run the command:

ifconfig

2. Basic configuration

After your RPi has booted successfully, log in either on the console or by ssh with user root and password raspberry. Follow these steps to complete the initial configuration:
Choose your timezone:

dpkg-reconfigure tzdata

Configure locale settings:

dpkg-reconfigure locales

Configure keyboard settings (not needed when working with ssh only):

dpkg-reconfigure keyboard-configuration

3. Email setup

Email delivery from your RPi is needed if you plan to have voicemails sent to users by email. Email already works in the default configuration using Exim4 as MTA. By default, Exim is configured to directly send mails to the recipient MX hosts. This is however discouraged, as many email providers classify emails coming from dynamic IP adresses as spam. To avoid this, you need to set a smarthost. Unless you have an open SMTP server on your network that can be used as smarthost without authentication, you will need to specify SMTP authentication credentials as well. It is basically possible to use almost any publicly available freemailer as smarthost with the RPi. Have username and password as well as SMTP hostname (sometimes also referred to as outgoing mail server) of the email account you are going to use ready. Run on the console:

dpkg-reconfigure exim4-config

On the first configuration page select “mail sent by smarthost; no local mail”. On the following pages just keep the default values by pressing enter, until you reach the page starting with “Please enter the IP address or the host name of a mail server…”. Here, enter the SMTP hostname of your email provider. Again, keep default values on the remaining pages.
Then, edit the file passwd.client by running:

nano /etc/exim4/passwd.client

Add your credentials at the bottom of this file in the following format:

SMTP_HOSTNAME:USERNAME:PASSWORD

In most cases, the SMTP hostname used in this file is identical to the hostname used as smarthost before. If email fails to work, specify the reverse lookup of your email provider’s SMTP host IP address here. For Google Mail, this is currently gmail-smtp-msa.l.google.com
Some email providers also require you to use sender addresses identical to one of the public email adresses of your account. In this case, edit:

nano /etc/email-addresses

On the bottom of this file add:

root: your_email@someisp.com
asterisk: your_email@someisp.com

This configures the sender address of all outgoing mail to your_email@someisp.com.
Finally, to activate your configuration run:

update-exim4.conf

You can test your email setup with this command:

send_test_email your_email@someisp.com

A test email should reach your inbox shortly.

4. Initial Asterisk setup

Point your browser to the RPi’s hostname or IP address (http://raspbx).
The default login to FreePBX is:
user: admin
password: admin
For inital setup please follow this guide:
http://www.freepbx.org/support/documentation/installation/first-steps-after-installation
Most of the configuration steps presented here apply to the RPi as well. If you are going to use SIP technology, you absolutely need to follow section 5, “Configure Asterisk SIP Settings”. After filling the Asterisk SIP Settings page, you need to go back to the console and run:

amportal restart

This step is only required once after Asterisk SIP Settings have been configured for the first time. For all other configuration changes just use the red apply config button in the GUI.

trying to do a reinstall of a package still means some dpkg work.

here is a cheat sheet.

http://www.cyberciti.biz/howto/question/linux/dpkg-cheat-sheet.php

dpkg command cheat sheet for Debian Linux

dpkg is package manager for Debian Linux which is use to install/manage individual packages. Here is quick cheat sheet you will find handy while using dpkg at shell prompt:

Syntax	Description	Example
dpkg -i {.deb package}	Install the package	dpkg -i zip_2.31-3_i386.deb
dpkg -i {.deb package}	Upgrade package if it is installed else install a fresh copy of package	dpkg -i zip_2.31-3_i386.deb
dpkg -R {Directory-name}	Install all packages recursively from directory	dpkg -R /tmp/downloads
dpkg -r {package}	Remove/Delete an installed package except configuration files	dpkg -r zip
dpkg -P {package}	Remove/Delete everything including configuration files	dpkg -P apache-perl
dpkg -l	List all installed packages, along with package version and short description	dpkg -l dokg -l \| less dpkg -l 'apache' dpkg -l \| grep -i 'sudo'
dpkg -l {package}	List individual installed packages, along with package version and short description	dpkg -l apache-perl
dpkg -L {package}	Find out files are provided by the installed package i.e. list where files were installed	dpkg -L apache-perl dpkg -L perl
dpkg -c {.Deb package}	List files provided (or owned) by the package i.e. List all files inside debian .deb package file, very useful to find where files would be installed	dpkg -c dc_1.06-19_i386.deb
dpkg -S {/path/to/file}	Find what package owns the file i.e. find out what package does file belong	dpkg -S /bin/netstat dpkg -S /sbin/ippool
dpkg -p {package}	Display details about package package group, version, maintainer, Architecture, display depends packages, description etc	dpkg -p lsof
dpkg -s {package} \| grep Status	Find out if Debian package is installed or not (status)	dpkg -s lsof \| grep Status

{package} - Replace with actual package name

here is the home page for this effort. Not simple, for sure

http://www.raspberry-asterisk.org/

hints:

the ITU code for the US is 1 (as in the digit you dial for a country code). for some reason one install attempt I made came up with 61 for Australia, and offered the code for Italy as well, both useless and wrong.

In my case there is a KVM blocking the monitor detection in this case, so the resolutions are defaulted to VESA.

Add 1600 x 1200 for Viewsonic P815 on Dell 745 optiplex

Change Resolution of Unknown Monitor in Ubuntu 11.10

I have the HP v185e Monitor and it was unrecognizable by my Ubuntu 11.10. The “Display” setting shows “Unknown Monitor”, and the maximum resolution I could get is 1024 x 768, the optimal resolution is 1368 x 768. I found that the “Unknown Monitor” could be set with XRandr from the posting in the Ubuntu Forum.
I did that right and the resolution is 1368 x 768, but after restarting, the resolution options were reverted back to 1024 x 768. From the Ask Ubuntu, I found that Ubuntu 11.10 have different way to permanenting the XRandr customization than it’s predecessors.

Here’s the summary (I’m using the example of adding 1440 x 900 resolution):

Open Terminal and type

$ xrandr

The XRandr will show the maximum resolution allowed like this:

Screen 0: minimum 320 x 200, current 1368 x 768, maximum 8192 x 8192
VGA1 connected 1368x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1368x768_60.00   59.9*+
   1024x768       60.0  
   1024x768_60.00   59.9  
   800x600        60.3     56.2  
   848x480        60.0  
   640x480        59.9  
   1280x800_60.00   59.8  
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)

Type “cvt [x resolution] [y resolution]” in the terminal, for my case is like this:

$ cvt 1440 900

The Terminal will show the output:

# 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz
Modeline "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync

For the next step, type:

$ xrandr --newmode [Modeline]

$ xrandr --newmode "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync

To add the new resolution to the “Display” option type:

$ xrandr --addmode VGA1 1440x900_60.00

To apply the new resolution, type:

$xrandr --output VGA1 --mode 1440x900_60.00

In order to make it permanent, add the resolution to /etc/X11/xorg.conf

$ sudo gedit /etc/X11/xorg.conf

The xorg.conf will show the output like this:

Section "Monitor"
    Identifier    "Monitor0"
    Modeline "1280x800_60.00"   83.50  1280 1352 1480 1680  800 803 809 831 -hsync +vsync
    Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
    Modeline "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Card0"
    Monitor        "Monitor0"
    SubSection "Display"
        Modes      "1280x800_60.00" "1368x768_60.00" "1024x768_60.00"
    EndSubSection
EndSection

Section "Device"
    Identifier    "Card0"
    Driver        ""
EndSection

Add the new Modeline and resolution, for the “Driver” in the “Section Device” I just simply type “Intel” (because I’m using intel standard graphic card), if you are using Nvidia just simply type “nvidia”. The output is like:

Section "Monitor"
    Identifier    "Monitor0"
    Modeline "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync
    Modeline "1280x800_60.00"   83.50  1280 1352 1480 1680  800 803 809 831 -hsync +vsync
    Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
    Modeline "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Card0"
    Monitor        "Monitor0"
    SubSection "Display"
        Modes      "1440x900_60.00" "1280x800_60.00" "1368x768_60.00" "1024x768_60.00"
    EndSubSection
EndSection

Section "Device"
    Identifier    "Card0"
    Driver        "intel"
EndSection

Restart and see the resolution setting is now permanent

Hope it worked

Note: from above articles writing to present, package install has changed form

apt-get -y install smbfs

to

apt-get -y install cifs-utils

Now, if it worked, you should see your mount right on the desktop. Browse through it, play music from it, watch movies from it (network speed permitting). Here are some common errors:

mount error: can not change directory into mount target... - either you didn't create your /media/my_share directory or specified it wrong in your mount command.
mount error 13 = Permission denied - your username and password are being rejected. Try some other combinations
mount error 6 = No such device or address - the share_name that you specified in your mount command is not being found on the host computer. Browse the network, find that computer, and check to make sure you see the exact share name.

I think this might be served up from a dyndns home system, so am capturing it here. On the hunt for OBS info.

this puzzle part relates to obs2obs copy and tag creation.

http://saigkill.homelinux.net/entry/2011/07/15/how-to-use-three-open-build-service-source-services-to-simplify-the-packaging

This is a short HowTo about using the OBS Source Services.
Sometimes a packager has a package who changes the Sourcecode very often. So the packager has to choose: On the first hand he can checkout the code from git or svn makes a tar.gz or bz2 from it or he can use the Source Services from the Buildservice. But how to do that?
In the following Example i'm using calligra from the KDE:Active Repository.
First of all i have uploaded the needed specs and *.changes files and all optional Sources. Then i'm going to the "Sources" Tab.In my case it looks like:

There we have two ranges. The first is called "Source Services" and the second "Source Files". If you are creating an new package this range is empty.
In my case i have filled the "Source Files" Range with my files. All my uploaded Files are in Section (2) from the Image. The Files in Section (3) will be automaticly created by the Source Services. But in your case this is empty Range.
But let us show the "Source Service" Section:

If you go to (1) "Add Service for Source Processing" you see this:

In this Overview you can choose your wanted Source Processor. In my case i choosed: tar_scm, recompress and update_sources.
If you choose tar_scm you can fill out a little form. It looks like:

In the field "url" you can add the full git adress. In my case it is "git://anongit.kde.org/calligra". Other Repositories like "git://anongit.kde.org/scratch/cschumac/polka.git" are possible too. In the field "scm" you can choose the Version Control System like git, svn, hg and bzr.
In the Standardform the field "versionprefix" isn't available. But it works.
The Source Services recompress and update_sources coming out without any configuration and working out of the box. So the OBS works like:

fetch the data from scm
recompress the *.tar to *.tar.gz
make a temp spec file with changed versiontag (used that from the source)
make a build

My Problem was now that i got a File like %{name}-%{gitversion} so it looks like calligra-1234567.tar.gz But my goal was to get calligra-2.3.90.git1234567.tar.gz. So i must set the versionprefix.
For doing that you must edit the file "_service". You can just click on it and choose "Edit File". The File itself is a simple XML File, so it is human readable. :-)
That's my file content:

<service name="tar_scm"><param name="url">git://anongit.kde.org/calligra</param><param name="scm">git</param>

The _services file is the control file for all services in that package. For adding the parameter "versionprefix" i've added the marked line.

After that i got my prefered format.

The Source Services are a mighty. You can download a special file and use it, or you can check the checksum with md5. I can see in this Source Services a very good potencial.

If you want to read more about that, just go to doc.openSUSE.org.

ATM it looks for me, that if you must start the services manually daily, if you want to update the sources. But all in all you can save time if you use that great tools.

If you liked this short intro or not, i'm happy about comments and trachbacks ;-)

utility for configuring or connecting to ports

http://communities.vmware.com/message/1741943

quote:

As far as I could gather, there is/was no easy way to do what I wanted to do. That said, I was able to cobble together a solution.

First of all, VMware sells an additional license called the "Remote Virtual Serial Port Concentrator" license (for way too much money, IMO) per ESXi server, which is what allows one to pipe a virtual machine's serial port out to a telnet port, using a telnet daemon running on the ESXi server. Paying the money and getting this license was the first step. Thankfully, VMware's turnaround was quick enough after we paid the money, that we were able to install these permanent licenses before the temporary, evaluation licenses expired.

The next step was to dynamically configure this serial port for my virtual machines. I could find no VMware-supplied API's, so I hacked my own perl script. I've attached it in case others find it useful, warts and all. I put in lots of comments since I was learning how to do this and I'm sure there's extra junk in there that's not needed, but it's working for me. Use at your own risk.

installation: use the automatic installer for the install

desktop: use cde. it still works.
/usr/dt/bin/Xsession is used to create the session. use it with vncserver to get rid of the horrid twc desktop (at least there is a default, not a crash, but still.)

nfs mounts: nfs version 3 should be max for this place. many of the nfs servers don't support the version 4 authentication and will say "not owner" when you do mounts. Ubuntu supports 4, readynas does not.

nfs partitions:
http://www.ogre.com/node/64

paths: very few paths are set up. Add /usr/X11/bin and /usr/openwin/bin to the path somewhere, or vncserver won't work (and probably a lot else).

useradd -m -d /export/home/<account> creates an account with a home directory. /home is off limits. useradd doesn't add on the user name so you have to supply it with this command. after this use passwd.

if you mess up usermod will let you change some things.

Probably more to it with the kerberos stuff, and roleadd, rolemod, etc.

Simple step by step guide to mounting Sparc-based ReadyNAS Drives in x86-based Linux:
Tested on brand new install of Ubuntu 10.10 (32bit x86), no other dependencies- 23rd Jan 2011
In a terminal window:
(1) sudo su
(2) apt-get install fuseext2
(3) apt-get install lvm2
(4) modprobe fuse
(5) vgscan
(6) vgchange -ay c
(7) fuseext2 -o ro -o sync_read /dev/c/c /mnt
That’s it!!!
You can now see the mounted files in the /mnt directory
(NB: Without the “-o sync_read” option to fuseext2 I had problems with copying large files. It kept saying the source file wasn’t found. After adding this option everything worked fine).
************************************************
Original Post
When the ReadyNAS developers changed the default block size in RAIDiator 4.x to 16 KB (from 4 KB in version 3.x), there was concern from the community that users would be unable to mount drives from a failed ReadyNAS into a Linux computer. The concern is that the ReadyNAS Duo, NV+, X6, 600 & 1100 use a Sparc-based processor and that an x86-based PC cannot read 16 KB blocks. One of the developers, Skywalker, has provided some details and I have taken the liberty of editing his posts into an easy-to-follow step-by-step set of instructions.

Quoting Skywalker:

There is no “proprietary” filesystem running on any ReadyNAS. It is “straight”, ordinary, unmodified EXT3. You can even run all the e2fsprogs (debugfs, e2fsck, etc) on a 16KB ReadyNAS filesystem on a standard Linux PC with no modifications. Mounting a 16KB ReadyNAS filesystem on an x86 PC requires about the same amount of work as mounting an NTFS filesystem read/write on Linux — using a FUSE driver to mount it.
The ext2fuse driver won’t come on any LiveCDs, so you’d need a full distro running with the necessary build tools installed.
Ubuntu, Fedora, Debian… it doesn’t really matter. Once you get those installed, you need to get the ext2fuse source code from sourceforge.net.

Using Debian, you can install the build tools by issuing the following command as root:

apt-get install build-essential

Download the ext2fuse package and extract it:

tar xvzf ext2fuse-src-0.8.1.tar.gz

Change to the directory of the extracted program
Run the following command:

./configure

Before compiling, open src/Makefile in an editor.
Remove the lines that look like this:

ext2fuse_DEPENDENCIES = ../lib/et/libcom_err.a \

../lib/ext2fs/libext2fs.a

Change this line:

ext2fuse_LDADD = ../lib/et/libcom_err.a ../lib/ext2fs/libext2fs.a

To this:

ext2fuse_LDADD = -lcom_err -lext2fs

Then build the executable by running make:

make

Next, install the package by running make install:

make install

After compiling and installing the package, you’ll need to load the fuse module:

modprobe fuse

Next, run the following commands to recover the volume group information and then activate it:

vgscan

vgchange -ay c

Create a directory to mount the array:

mkdir /mnt/lvm

Mount the array:

ext2fuse /dev/c/c /mnt/lvm

If successful, you should see:

/dev/c/c is to be mounted at /mnt/lvm

fuse-ext2 initialized for device: /dev/c/c

block size is 16384

At this point, your ReadyNAS data volume should be mounted on /mnt/lvm and you should be able to access your data.

I haven’t tried this myself (I gave my NV+ to my dad), but welcome any feedback on making it better.
Update (May 22, 2010) – Have a look at this for additional information:
http://greyproc.blogspot.com/2010/04/readynas-600-raid-recovery-with-ubuntu.html

Alternative Method

If you are trying to recover data from a Duo (or from a disk with only 1 or 2 disks in the array), then you may be able to recover the data using the following method:

Connect your faulty disk to PC using a SATA to USB cable
Download, install & run the free software R-Linux from www.r-tt.com
Copy the recovered data from the faulty disk

Thanks dbott – very useful and clear site! Currently backing up thousands of pics off my 3 NAS drives from an Ubuntu box
I managed to bypass the compilation step by using an older pre-built ext2fuse 0.5 from here:

From the blog linked to above:
Choosing a NAS solution where you can’t mount the storage media outside of the NAS is asking for trouble. I was worried I’d made the wrong choice when I found that mounting the ReadyNAS do ext3 drives is not trivial, mainly because they use a 16kb block size with their SPARC cpus.
A bit of routing around found various solutions, but the one which worked for me was as follows.
1. Fire up ubuntu vm (running on OS X for me and in my case 9.10 Karmic)
2. install lvm2 using: apt-get install lvm2
3. Download ext2fuse 0.5 (from here for example)
http://linux.softpedia.com/progDownload/ext2fuse-Download-29820.html
http://sourceforge.net/projects/ext2fuse/files/ext2fuse/0.5/ext2fuse-0.5.src.tgz/download
4. run vgscan to locate drives
5. vgchange -ay c to allow access to drive
6. mkdir /mnt/lvm
7. ext2fuse /dev/c/c /mnt/lvm (where ext2fuse will have been downloaded)
8. drive can now be accessed on /mnt/lvm

ext2fuse is no longer active and apparently redundant based on comments on the project itself. It seems to be superseded by a another project called fuse-ext2.
I’m using ubuntu 10.10 and I found a ‘fuseext2′ package in the repository and it worked with no problems. Although it complained that it’s experimental and to only use write option at your own risk, and so because I only need this to get my data off the disk I simply mounted it are read only:
fuseext2 -o ro /dev/c/c /mnt/lvm/

Hi
I’v tried to mount a disk from a 2 disk Duo with Ubuntu 10.10. vgscan dosent locate the disk but I can se it in the diskutility. How can I find the name of the disk so that I can run “vgchange -ay c” ?
Richard Millington Says:
March 30th, 2011 at 6:01 am
Thanks. Peter Schlesinger’s method works fine for me in LinuxMint 9, even though (4) modprobe fuse returned an error.
Installed fuseext2 and lvm2 from the repositories.
In terminal ran 5,6, and 7.
Copy needed files.
Change owner. (Copied files will be root)
chown -R (user) /home/user/folder_name
May need to changed permissions also.
chmod -R a=rwx /home/user/folder_name
Maybe Peter Schlesinger could make this a ‘sticky’ in the ReadyNas forums.
Again – Thanks

Hi, just like ext2fuse, fuseex2 on Ubuntu 10.10 is not allowing me to copy files > 4GB onto another ext3 system. The portion of file >4gb is rewritten from the start, so that files never end up greater than 4GB.
Has anyone managed to work around this? I tried compiling fuse-ext2-0.0.7 on Ubuntu, but the compile doesn’t produce an executable. The changelog said it had fixed the >4gb problem

Hi Mathias
The free software for windows “R-Linux” did the job for me.
http://www.r-tt.com/free_linux_recovery/
It took some time for it to scan my disk, but it found all my data with folders and the right file names and extensions.
Try it !!

@Peter Schlesinger ,
Brian Ost has already said:
“vgscan dosent locate the disk but I can see it in the diskutility. How can I find the name of the disk so that I can run “vgchange -ay c” ?”
What are we doing wrong?
Do we have to make Local Volumes?
I used fresh installed Ubuntu 10.04 LTS
Frederic Says:
April 30th, 2011 at 12:03 am
The method doesn’t work for me.
The vgscan doesn’t detect my drive.
# vgscan
Reading all physical volumes. This may take a while…
#
When I try to mount it manually the system return to me:
# mount /dev/sdb1 /mnt/lvm
mount: unknown filesystem type ‘linux_raid_member’
This drive was used previously as RAID but not in my last configuration.
Have you any idea to help me to mount this drive? Something is wrong with vgscan but I don’t know what.

vmware

vlance, vmxnet, flexible, e1000, e1000e, vmxnet2, vmxnet3

Available Network Adapters

Only those network adapters that are appropriate for the virtual machine you are creating, are available configuration options in the Choose Networks window.

Vlance — An emulated version of the AMD 79C970 PCnet32- LANCE NIC, an older 10Mbps NIC with drivers available in most 32-bit guest operating systems except Windows Vista and later. A virtual machine configured with this network adapter can use its network immediately.
VMXNET — The VMXNET virtual network adapter has no physical counterpart. VMXNET is optimized for performance in a virtual machine. Because operating system vendors do not provide built-in drivers for this card, you must install VMware Tools to have a driver for the VMXNET network adapter available.
Flexible — The Flexible network adapter identifies itself as a Vlance adapter when a virtual machine boots, but initializes itself and functions as either a Vlance or a VMXNET adapter, depending on which driver initializes it. With VMware Tools installed, the VMXNET driver changes the Vlance adapter to the higher performance VMXNET adapter.
E1000 — An emulated version of the Intel 82545EM Gigabit Ethernet NIC. A driver for this NIC is not included with all guest operating systems. Typically Linux versions 2.4.19 and later, Windows XP Professional x64 Edition and later, and Windows Server 2003 (32-bit) and later include the E1000 driver.

Note: E1000 does not support jumbo frames prior to ESX/ESXi 4.1.
E1000e - This feature emulates a newer model of Intel gigabit NIC (number 82574) in the virtual hardware. This is known as the "e1000e" vNIC. e1000e is available only on hardware version 8 (and newer) VMs in vSphere5. It is the default vNIC for Windows 8 and newer (Windows) guest OSes. For Linux guests, e1000e is not available from the UI (e1000, flexible vmxnet, enhanced vmxnet, and vmxnet3 is available for Linux).
VMXNET 2 (Enhanced) — The VMXNET 2 adapter is based on the VMXNET adapter but provides some high-performance features commonly used on modern networks, such as jumbo frames and hardware offloads. This virtual network adapter is available only for some guest operating systems on ESX/ESXi 3.5 and later.

VMXNET 2 is supported only for a limited set of guest operating systems:
- 32- and 64-bit versions of Microsoft Windows 2003 (Enterprise, Datacenter, and Standard Editions).
  
  Note: You can use enhanced VMXNET adapters with other versions of the Microsoft Windows 2003 operating system, but a workaround is required to enable the option in VMware Infrastructure (VI) Client or vSphere Client. See Enabling enhanced vmxnet adapters for Microsoft Windows Server 2003 (1007195) if Enhanced VMXNET is not offered as an option.
- 32-bit version of Microsoft Windows XP Professional
- 32- and 64-bit versions of Red Hat Enterprise Linux 5.0
- 32- and 64-bit versions of SUSE Linux Enterprise Server 10
- 64-bit versions of Red Hat Enterprise Linux 4.0
- 64-bit versions of Ubuntu Linux
In ESX 3.5 Update 4 or higher, these guest OS are also supported:
- Microsoft Windows Server 2003, Standard Edition (32-bit)
- Microsoft Windows Server 2003, Standard Edition (64-bit)
- Microsoft Windows Server 2003, Web Edition
- Microsoft Windows Small Business Server 2003

Note: Jumbo Frames are not supported in the Solaris Guest OS for VMXNET 2.

VMXNET 3 — The VMXNET 3 adapter is the next generation of a paravirtualized NIC designed for performance, and is not related to VMXNET or VMXNET 2. It offers all the features available in VMXNET 2, and adds several new features like multiqueue support (also known as Receive Side Scaling in Windows), IPv6 offloads, and MSI/MSI-X interrupt delivery.

VMXNET 3 is supported only for virtual machines version 7 and later, with a limited set of guest operating systems:
- 32- and 64-bit versions of Microsoft Windows XP,7, 2003, 2003 R2, 2008, and 2008 R2
- 32- and 64-bit versions of Red Hat Enterprise Linux 5.0 and later
- 32- and 64-bit versions of SUSE Linux Enterprise Server 10 and later
- 32- and 64-bit versions of Asianux 3 and later
- 32- and 64-bit versions of Debian 4
- 32- and 64-bit versions of Ubuntu 7.04 and later
- 32- and 64-bit versions of Sun Solaris 10 U4 and later
Notes:
- In ESX/ESXi 4.1 and earlier releases, Jumbo Frames are not supported in the Solaris Guest OS for VMXNET 2 and VMXNET 3. The feature is supported starting with ESXi 5.0 for VMXNET 3 only.
  
  For more information, see Enabling Jumbo Frames on the Solaris Guest OS (2012445).
- Fault Tolerance is not supported on a virtual machine configured with a VMXNET 3 vNIC in vSphere 4.0, but is fully supported on vSphere 4.1.

Setup of motion, RTL8188CUS realtek based wifi & UVC webcam

Post a reply

Hi all.

Hopefully this will be of interest and help to someone trying to get a uvc webcam and/or realtek wifi dongle working on their rpi.

I hope this is the correct place to post this kind of topic.

*******************************************************************************************
Why.....

I wanted to have a rpi with a wifi dongle & a uvc logitech webcam and motion installed.

Problem.....
Arch, has the webcam modules but unable to get the rpi arch image to
support either of my 2 RTL8188CUS realtek based dongles.

: Belkin surf n150 micro adapter
: Edimax N150 Wireless nano USB Adaptor

Debian, doesn't immediately work with the dongle, but fairly easy to get working using this great
script: viewtopic.php?f=26&t=6256

But.... the default rpi Debian kernel doesn't have the uvc webcam stuff.
So I cant use the script above, because I need to bake in the webcam.

So...these instructions should enable you to have a:

1) debian based distro (custom kernel)
2) wifi working with RTL8188CUS based adapters.
3) logitech webcam working.

*******************************************************************************************

What you will need

1 x linux machine
1 x rpi
1 x SD card
Wired network between rpi & linux machine
1 X Realtek based wireless dongle. !DO NOT PLUG IN UNTIL TOLD TO!
1 X Logitech webcam

*******************************************************************************************

Getting started..

Prepare SD with the debian6-19-04-2012.zip image from http://www.raspberrypi.org/downloads

Lots of methods to do this.. take a look at:

http://elinux.org/RPi_Easy_SD_Card_Setup

Resize SD card if you need to gparted on your linux machine is your friend.

*******************************************************************************************

Boot for the first time.

Login as the user you have been given as part of the download for your initial image and change the password

Change your user (pi) password

Code: Select all: # passwd

Change the root passwd

Code: Select all: # sudo passwd

Switch to root

Code: Select all: # su

Enter the password you just changed

Get everything up to date

Code: Select all: # apt-get update # apt-get update [to clear duplicates] # apt-get upgrade

At this point I normally (2xpi, 2xpowerAdapters ) get a kernel panic on first upgrade
Just pull plug out and reboot

Login as root this time

Code: Select all: # apt-get upgrade

I want a fixed IP on this machine so I can find it when i disconnect the monitor
dont do this if you want the wired to be dhcp

*startOfDontDoThisIfYouDontWant

Code: Select all: # vi /etc/network/interfaces

(of course you could you emacs here)

Change the following line

Code: Select all: iface eth0 inet dhcp

to

Code: Select all: iface eth0 inet static address 192.168.0.80 <---- whatever is applicable to your lan config netmask 255.255.255.0 <---- whatever is applicable to your lan config network 192.168.0.0 <---- whatever is applicable to your lan config gateway 192.169.0.1 <---- whatever is applicable to your lan config

Then to write the file

Code: Select all: :wq!

Code: Select all: # ifdown eth0 # ifup eth0

* if after the next reboot you lose your ability to resolve hostnames
* i.e. ping google.com --> unknown host google.com
* just add:

Code: Select all: nameserver 8.8.8.8 (or your favourite DNS server IP address)

* to the bottom of /etc/resolv.conf

endOfDontDoThisIfYouDontWant

To see (or check ) the address assigned to your eth0 network interface

Code: Select all: # ifconfig

eth0 inet addr, should be either a dhcp address or the one you set in the interfaces file.

Now I want to install Hexxeh/rpi-update tool
From here: https://github.com/Hexxeh/rpi-update

Code: Select all: # cd # mkdir hexxeh # cd hexxeh # apt-get install ca-certificates # apt-get install git

Code: Select all: # wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update && chmod +x /usr/bin/rpi-update # rpi-update

Dont worry if you get this:

Code: Select all: /opt/vc/sbin/vcfiled: error while loading shared libraries: libvchiq_arm.so: cannot open shared object file: No such file or directory

* Always happens and no one seems worried about it.

Ok..... lets leave our rpi alone for a minute.

On our second linux (Ubuntu in my case) machine

(A lot of this next bit sourced from here: http://elinux.org/RPi_Kernel_Compilation)

Code: Select all: # sudo apt-get install gcc-4.6-arm-linux-gnueabi # sudo apt-get install git-core # cd # mkdir raspberrypi # cd raspberrypi # git clone https://github.com/raspberrypi/linux.git # cd linux # sudo ln -s /usr/bin/arm-linux-gnueabi-gcc-4.6 /usr/bin/arm-linux-gnueabi-gcc # cp arch/arm/configs/bcmrpi_cutdown_defconfig .config # make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- oldconfig # make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- -k

Depending on your machine this might take a while.

(You can use -j flag if you have multi-core see notes on above url
you might have to press ENTER a lot)

This will have create a kernel image in: /home/yourUser/raspberrypi/linux/arch/arm/boot/
called: "zImage"
Now we need to copy it to our pi

* back on the pi....

Code: Select all: # apt-get install sshfs # cd /mnt # mkdir linux # sshfs yourUserName@yourLinuxMachineIPorHostname:/home/yourUser/raspberrypi/linux linux

You can check it mounted okay by:

Code: Select all: # df -kh

* will show you that /mnt/linux is mounted to yourLinuxMachines linux directory

Code: Select all: # cd linux # make modules_install # cd /boot # cp kernel.img /root/backup-original-kernel.img

Now copy your new kernel over....

Code: Select all: # cp /mnt/linux/arch/arm/boot/zImage kernel.img

You can check it worked by doing this....

Code: Select all: # diff kernel.img /root/backup-original-kernel.img Binary files kernel.img and /root/backup-original-kernel.img differ #reboot

Fingers crossed

Now to get the wireless driver working........

Back on your Linux Machine.

Code: Select all: # cd # cd raspberrypi # mkdir wifi

Grab the UNIX (Linux) RTL8192CU driver package from http://www.realtek.com.tw
its a long url... but this shortLink should get you there.... http://goo.gl/81MRD
the file should be called something like this: RTL819xCU_USB_linux_v3.4.2_3727.20120404.zip

* Save the downloaded zip file in the wifi directory you just created
*! there must be a way of building this on the pi but I could not get it to work.
*! annoying as it means I cant use the install script.

Code: Select all: # cd # cd raspberrypi/wifi # unzip RTL819xCU_USB_linux_v3.4.2_3727.20120404.zip # cd RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404 # cd driver # tar -zxvf rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404.tar.gz # cd rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404/ # make KSRC=/home/yourUserName/raspberrypi/linux/ ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- -k # ls -ltrh

[you will now see you have a brand spanking new]

8192cu.ko

kernel module, that has been compiled to work with the kernel you prepared earlier.

Back to the rPi

Code: Select all: # cd /mnt # mkdir wifi # sshfs yourUserName@yourLinuxMachineIPorHostname:/home/yourUser/raspberrypi/wifi wifi # cd /mnt/wifi/RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404/driver/rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404 # cp 8192cu.ko /root # cd # install -p -m 644 8192cu.ko /lib/modules/3.1.9+/kernel/drivers/net/wireless/

Blacklist bad module

Code: Select all: # echo 'blacklist rtl8192cu' >> /etc/modprobe.d/blacklist.conf # # echo >> /etc/network/interfaces <--- put a blank line at the bottom of our interfaces file. # echo "allow-hotplug wlan0" >> /etc/network/interfaces <---- if we want to allow hotplug of our adapter # echo >> /etc/network/interfaces # echo 'auto wlan0' >> /etc/network/interfaces <-- create an entry for our wlan0 # echo >> /etc/network/interfaces # echo 'iface wlan0 inet dhcp' >> /etc/network/interfaces <-- we can change this to static if it works. # echo 'wpa-ssid "putYourSSIDhere" ' >> /etc/network/interfaces <--- this is the name of your wireless Lan. # echo 'wpa-psk "putYourWirelassPasswordHere" ' >> /etc/network/interfaces # echo '8192cu' >> /etc/modules # depmod -a

Ok NOW plug in your wifi usb adapter..

Code: Select all: # iwconfig

You should see something like this......

Code: Select all: lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"YourWifiNetworkName" Nickname:"<WIFI@REALTEK>" Mode:Managed Frequency:2.462 GHz Access Point: XX:YY:ZZ:AA:BB:CC Bit Rate:150 Mb/s Sensitivity:0/0 Retry:off RTS thr:off Fragment thr:off Encryption key:****-****-****-****-****-****-****-**** Security mode:open Power Management:off Link Quality=94/100 Signal level=44/100 Noise level=0/100 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Code: Select all: # ifconfig

Should give you something like this

Back on your linuxMachine

Code: Select all: # ping 192.168.0.81 64 bytes from 192.168.0.81: icmp_seq=0 ttl=64 time=0.993 ms

Lets reboot and make sure it all works then.....

Code: Select all: # reboot

Ok... the goal of this for me is a rpi with wifi, camera and motion so actually I need to set
the wifi address to be static so I can connect to it, otherwise it will keep changing and without
a keyboard and screen attached it will be a pain.

Login to your rpi as root (or just prefix all commands with sudo, up to you.)

Code: Select all: # vi /etc/network/interfaces

change the following line

Code: Select all: iface wlan0 inet dhcp

to

Code: Select all: iface wlan0 inet static address 192.168.0.81 <---- whatever is applicable to your lan config, not an address handed by your dhcp server netmask 255.255.255.0 <---- whatever is applicable to your lan config network 192.168.0.0 <---- whatever is applicable to your lan config gateway 192.169.0.1 <---- whatever is applicable to your lan config

Then to write the file

Code: Select all: :wq!

Code: Select all: # ifdown wlan0 # ifup wlan0 # ifconfig

This should give you something like this

Code: Select all: wlan0 Link encap:Ethernet HWaddr XX:YY:ZZ:AA:BB:CC inet addr:192.168.0.80 Bcast:192.168.0.255 Mask:255.255.255.0

Back on your linux machine open a terminal window and

Code: Select all: # ssh root@9192.168.0.81

* enter your password

Code: Select all: ## hostname raspberrypi

OK all good, we dont need a screen or keyboard anymore.
Now unplug the keyboard from the rpi, we will need the usb for your webcam.
Plug your webcam in

Code: Select all: # dmesg (in your terminal window)

You should see something like this...

Code: Select all: usb 1-1.2: new high speed USB device number 6 using dwc_otg usb 1-1.2: New USB device found, idVendor=046d, idProduct=0825 usb 1-1.2: New USB device strings: Mfr=0, Product=0, SerialNumber=2 usb 1-1.2: SerialNumber: AB81D3F0 Linux video capture interface: v2.00 uvcvideo: Found UVC 1.00 device <unnamed> (046d:0825) input: UVC Camera (046d:0825) as /devices/platform/bcm2708_usb/usb1/1-1/1-1.2/1-1.2:1.0/input/input2 usbcore: registered new interface driver uvcvideo USB Video Class driver (1.1.1) 6:3:1: cannot set freq 16000 to ep 0x86 6:3:2: cannot set freq 24000 to ep 0x86 6:3:3: cannot set freq 32000 to ep 0x86 6:3:4: cannot set freq 48000 to ep 0x86 usbcore: registered new interface driver snd-usb-audio rtw_set_ps_mode(): Busy Traffic , Leave 802.11 power save.. rtl8192c_set_FwPwrMode_cmd(): Mode = 0, SmartPS = 0

* I have tried this with the following webcams...
* logitech c120
* logitech c160

* lets see if a video device has been created.

Code: Select all: # ls -ltrh /dev/video* crw-rw---- 1 root video 81, 0 Jun 4 18:42 /dev/video0

* ok good.
* almost there..

Install motion

Code: Select all: # apt-get install motion # apt-get install uvcdynctrl # apt-get install guvcview # vi /etc/motion/motion.conf

Change: webcam_localhost on --> webcam_localhost off <--- this means we will be able to see the camera stream from other machines
Change: videodevice /dev/video0 To whatever video device was shown by ls -ltrh /dev/video*

Optional (but these are my settings):
Change: width 320 --> width 640 This will depend on your camera model.
Change: height 240 --> height 480
Change: framerate 25 --> http://www.lavrsen.dk/foswiki/bin/view/ ... nFramerate
Change: webcam_maxrate 25 --> http://www.lavrsen.dk/foswiki/bin/view/ ... camMaxrate
Change: output_normal on --> off , Im happy just to have the avi I can always jpeg split later if i want

Code: Select all: :wq! <--- Save your settings and exit.

Lets try it.

Code: Select all: # motion

All done.
