ASUS USB-N10 Nano on OpenSuse 13.1 Linux

Today I bought myself a wifi adapter for my Opensuse desktop PC. I was tired of running a network cable across the carpet to my modem.

The model I bought was an ASUS USB-N10 Nano from PB Technologies in Henderson. It was less than $20 so I thought a good deal. When I bought it, I completely ignored all the printed garbage about support for Windows and Mac and figured, that it will be supported under linux.

It is supported under Linux but it was not too simple to set up on my Opensuse.

In the end and after much google-ing, I found this repository:
https://github.com/pvaret/rtl8192cu-fixes

The driver that ships with the kernel is not so hot. The network keeps dropping even though it appears to remain connected. With this version, things are much more stable.

Also it compiles nicely under the latest kernel. The proprietry driver from Realtek did not compile under the kernel shipped with Opensuse 13.1.

So here is what I ended up doing:

~ git clone https://github.com/pvaret/rtl8192cu-fixes.git
~ su - (become root)
# zypper in dkms kernel-devel kernel-headers gcc make
# cd /path/to/git/repo... (you get the picture)
# cd ../ (go to directory above tree) on my system I put this source tree under /usr/local/src/
# dkms add rtl8192cu-fixes
# dkms install 8192cu/1.8
# depmod -a
# cp blacklist-native-rtl8192.conf /etc/modprobe.d
# echo "options 8192cu rtw_power_mgnt=0 rtw_enusbss=0" > /etc/modprobe.d/50-8192cu.conf
# reboot

And that's it. Now if the kernel is ever updated during normal patching, dkms will recompile our driver.

EDIT:
I have made an RPM package for this driver. It's hosted on the openSUSE build service. Currently I have successfully managed to create rpm's for Centos, Redhat and Fedora (x86_64) only. The openSUSE one failed because the build environment does not have DKMS installed and so the install test fails at the very end.
Anyway - find the packages here: https://build.opensuse.org/package/show/home:linuxplayground/8192cu-1.8

so the openSUSE version is here: 8192cu-1.8-1.0.x86_64.rpm

These RPM packages will:
  • save the source in /usr/src/8192cu-1.8
  • Add the source tree to DKMS
  • Build the kernel module using dkms build ...
  • Install the kenrel module using dkms install ...

To uninstall the module and all the dkms source, builds and modules then just execute: #rpm -e 8192cu

Extending the AD Schema on Samba4 - Part 2

Importing LDIF files into Samba4 and Active Directory This is part 2 of the Extending AD Schema on Samba4 series.  The examples below are tested using the Samba4 LAB I created.  If you want more information on how that works then please read  http://david-latham.blogspot.co.nz/2012/12/samba4-ga-release-virtualbox-lab.html For part one, please read http://david-latham.blogspot.co.nz/2012/12/extending-ad-schema-on-samba4.html Unfortunately the format of an ldif file for creating new attributes and classes in the Schema Configuration are differ between Samba4 and Microsoft. The tools are slightly different too.  So this article will attempt to make it all clear. Find all the latest versions of code on this post at  https://github.com/linuxplayground/yubikey-ldap/tree/master/microsoft-schema Samba4 - ldbadd & ldbmodify As far as I can tell the only way to create a new class with a custom attribute in Samba4 (on the Linux command line) is first add ...

Automatically mount NVME volumes in AWS EC2 on Windows with Cloudformation and Powershell Userdata

Introduction This post explains how I go about with AWS Cloudformation and Powershell userdata scripts. attaching EBS volumes to Windows EC2 instances identifying them in the OS initializing them formatting them and assigning labels and drive letters. Prerequisites You should know something about Cloudformation and Powershell. The AWS Image you use for your EC2 instance should be one provided by AWS and should have the following utility already deployed to  C:\ProgramData\Amazon\Tools\ebsnvme-id.exe AWS Cloudformation Step I typically do not declare EBS Volumes together with the EC2 Instance declaration in Cloudformation but prefer to declare them as separate resources along with their own ebs attachment resources.  Here is an example EC2 instance with three additional volume declarations on top of the root volume which is automatically mounted on C:\ WindowsServerInstance: Type: AWS::EC2::Instance Properties: BlockDeviceMappings: - DeviceName: /dev/sda...

Extending the AD Schema on Samba4 - Part 1

Image
My last post on Samba4 showed how easy it is to install and configure an AD Service on Linux.  If you've not read it then please have a look. ( http://david-latham.blogspot.co.nz/2012/12/samba4-ga-release-virtualbox-lab.html ) This post show's how to extend the Samba4 Active Directory Schema.  Specifically for YubiKey integration. YubiKey's can be purchased for a relativlely low price from Yubico.  Please visit their website (www.yubico.com) for more information. LDAP Integration is very well covered by Michal Ludvig on his website and github.  ( http://www.logix.cz/michal/devel/yubikey-ldap/ ) In fact we are planning to leverage his implementation at our work and are considering donating towards what's obviously a very good cause. Now seeing as though LDAP and AD are so similar and exhibit many of the same APIs, I began to wonder how this might fit in with Samba4.  Eventually we might end up using Samba4 for our domain and so I needed to figure out if ...
