Drupal Debian Linux VirtualBox TroubleShooting Tips
Fix Virtual Network Interface Card to eth0
===========================================
When we move the image to various hosts,
1) the interface name will keep running to eth1, eth2, eth3 and so on
2) the ip address will not automatically obtained.
because inside /etc/network/interfaces
....
iface eth0 inet dhcp
...
For solution Go To network-interface-in-linux.html
HTTP request status Fails

Blacklist (Disable) Bluetooth kernel module in Debian
$ sudo /sbin/modinfo bluetooth
filename: /lib/modules/3.0.0-1-amd64/kernel/net/bluetooth/bluetooth.ko
alias: net-pf-31
license: GPL
version: 2.16
description: Bluetooth Core ver 2.16

depends: rfkill,crc16
intree: Y
vermagic: 3.0.0-1-amd64 SMP mod_unload modversions
parm: disable_esco:Disable eSCO connection creation (bool)
parm: disable_ertm:Disable enhanced retransmission mode (bool)

$ sudo vi /etc/modprobe.d/bluetooth.conf

Bluetooth coexistence
=================
http://wireless.kernel.org/en/users/Documentation/Bluetooth-coexistence
= An 802.11 device and Bluetooth can interfere with each other when the 802.11 device operates on the 2.4 GHz band.
All Bluetooth devices operate at the 2.4 GHz band.
ath9k supports Bluetooth coexistence
Ref http://wireless.kernel.org/en/users/Drivers/ath9k/btcoex
$ cat /sys/module/ath9k/parameters/btcoex_enable
To disable it
options ath9k btcoex_enable=0
Note
====
There is also a file called blacklist.conf inside the /etc/modprobe.d/ directory.
Do not add the blacklist
It won’t prevent the module from auto loading. In fact the beginning of that file states the same:
$ head /etc/modprobe.d/blacklist.conf
....
It does not affect autoloading of modules by the kernel. This file is provided by the udev package.
...
Related Information
===============
The easiest way to control the behavior of an init script is by changing environment variable assignments in the file named like the init script in the
/etc/default directory.Ref: http://qref.sourceforge.net/quick/ch-tune.en.html
$ sudo vi /etc/default/bluetooth
then set
BLUETOOTH_ENABLED=0
$ sudo update-rc.d bluetooth remove
$ cat /etc/modprobe.d/aliases.conf

NFS Ports
Ports
=====
The ports used by NFS RPC-based service can be listed by:
$ rpcinfo -p
While NFS uses port 2049 and portmapper uses port 111,
the underlying RPC mapper uses a variation of ports,
by default randomly assigned as part of the Sun specs.
rpc.statd :
A daemon that listens for reboot notifications from other hosts,
and manages the list of hosts to be notified when the local system reboots
If the -p option is not specified,
rpc.statd chooses a random ephemeral port for each listener socket.
-o, --outgoing-port
Specifies the source port number
for NFS server to send reboot notifications.
rpc.mountd :
The rpc.mountd program implements the NFS mount protocol.
The -p option force rpc.mountd to bind to the specified port num,
instead of using the random port number assigned by the portmapper.
Fix Ports
=======
/etc/default/nfs-common
STATDOPTS="-p 32765 -o 32766"
/etc/default/nfs-kernel-server
RPCMOUNTDOPTS="-p 32767"
Sample mounting options
===================
mount -v -t nfs -o proto=tcp,port=2049,mountport=32767 {Server-IP or Server Name}:/path/to/public /local/mount/directory
'man nfs' for more info
Configuring port forwarding with Virtualbox NAT for NFS Server
==============================================
As the virtual machine is connected to a private network internal to VirtualBox and invisible to the host,
network services on the guest are not accessible to the host machine or to other computers on the same network.
However, like a physical router, VirtualBox can make selected services available to the world outside the guest through port forwarding.
This means that VirtualBox listens to certain ports on the host and resends all packets which arrive there to the guest, on the same or a different port.
VBoxManage modifyvm "VM name" --natpf1 "guestnfs,tcp,,2049,,2049"
VBoxManage modifyvm "VM name" --natpf1 "gueststatd,tcp,,32765,,32765"
VBoxManage modifyvm "VM name" --natpf1 "guestnotify,tcp,,32766,,32766"
VBoxManage modifyvm "VM name" --natpf1 "guestmountd,tcp,,32767,,32767"
The NFS client can use the standard NFS port number of 2049 without first checking the server's rpcbind service.
This allows an NFS version 4 client to contact an NFS version 4 server through a firewall that may block rpcbind requests.

Change the scaling governor
============================
Ondemand governor
- sets the CPU frequency depending on the current usage.
This would be good for systems that do a lot of work (high load) for a short periods of time
and then don't do much (low load) the rest of the time.
Conservative governor
- CPU frequency is scaled based on current load of the system. It is similar to ondemand.
The difference is that it gracefully increases and decreases the CPU speed
rather than jumping to max speed the moment there is any load on the CPU.
This would be best used in a battery powered environment.
Powersave governor
- CPU runs at min frequency regardless of load.
Performance governor
- CPU runs at max frequency regardless of load.
$ sudo sh -c "echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor"
to set the desired scaling governor at boot-time.

Solution
=======
I reboot to a live cd (http://www.playoss.com/node/179)
mount internal hdd
download http://packages.debian.org/firmware-linux-nonfree
and extract the radeon to {mount-directory-of-debian-root}/lib/firmware
Useful commands

I reboot to a live cd (http://www.playoss.com/node/179)
mount internal hdd
download http://packages.debian.org/firmware-linux-nonfree
and extract the radeon to {mount-directory-of-debian-root}/lib/firmware

No sound on Realtek ALC269VB under Linux
As of 30/09/2011, ALC269VB is not the support model listed in
www.realtek.com/downloads/downloadsview.aspx?langid=1&pfid=24&level=4&conn=3&downtypeid=3
I thought it must be a key (e.g. laptop-amic) to define in /etc/modprobe.d/alsa-base.conf
for the sound card to work properly like
https://help.ubuntu.com/community/HdaIntelSoundHowto
and http://siripong-computer-tips.blogspot.com/2011/07/82801i-vostro-v13-debian-no-sound.html
After hours of trial and error changing snd-hda-intel model=auto, basic, asus
and reboots, there were no sounds from Realtek ALC269VB of ASUS X43B Series.
Finally, I found that the root cause was that
"the modern video-cards have an little audio support built-in, for HDMI.
In some cases, ALSA misunderstand where is the 'main' sound hardware".

Solution
======
The solution is simply set the default PCM device.
How to do that

Big Thanks to: http://alsa.opensrc.org/.asoundrc

$ aplay -L

# To set the default device, place a pcm.!default line in the .asoundrc
$ echo 'pcm.!default front:SB' > ~/.asoundrc
While aplay is still error, there are sounds from vlc and iceweasel.
