Trixbox message waiting indicator

Paul — Wed, 12 May 2010 15:10:16 +0000

After importing extensions with trixbox using the bulk extension tool you will have to preform a few changes. When an extension is imported the context is set wrong for the voicemail and mailbox. To correct this change the highlighted sections in the following two pictures from “device” to “default”.

Asterisk dialplan injection

Paul — Tue, 27 Apr 2010 23:50:45 +0000

Dialplan injection is great for preserving changes in a web ui distro such as trixbox. The released version 0.1.1 has an error in its SQL file that will break operation. The install.sql included with the package has error comments that breaks the MySQL import. I have also modified the table for extension varchar longer then 10 which will allow rules for long distance numbers.

Download the modified install.sql (patch)
Now load the modified SQL into your database
mysql -u root -p asterisk < install.sql
Note: trixboxes default root password is passw0rd (the o is a zero)

Alternatively here’s a bundled new installer (ver 0.1.1m) so you can follow these easy steps to install the dialplan injection module

cd /var/www/html/admin/modules
wget http://binfuser.com/wp-content/uploads/2010/04/dialplaninjection-0.1.1m.tgz
tar -xzvf dialplaninjection-0.1.1m.tgz
rm -f dialplaninjection-0.1.1m.tgz

Windows 7 nor Dell’s website offer any driver downloads for the audio driver on an Inspiron 6000

Download this driver for 32bit support.

Xen CentOS guest to VMware

Paul — Fri, 18 Dec 2009 19:29:36 +0000

use the vmware vcenter converter standalone
once the machine is in your esxi server
power it off and connect a centos install cd as your cd and make sure its connected on start
power on the vm and hit esc at the vmware bios post
boot from your centos install cd
at the boot: prompt enter linux rescue
select your language (im guessing english if your reading this)
and select your keyboard type
choose yes to start network interfaces (enter in your site config if need be or use dhcp as you will need internet access)
at the rescue operating system select continue
at the last rescue prompt press enter at the “ok”

chroot/mnt/sysimage

vi /etc/inittab
delete the line:
co:2345:respawn:/sbin/agetty xvc0 9600 vt100-nav
uncomment the following:
1:2345:respawn:/sbin/mingetty tty1
2:2345:respawn:/sbin/mingetty tty2
3:2345:respawn:/sbin/mingetty tty3
4:2345:respawn:/sbin/mingetty tty4
5:2345:respawn:/sbin/mingetty tty5
6:2345:respawn:/sbin/mingetty tty6

To install a pristine kernel
yum -y install kernel

And to purge the xen kernels
rpm -e kernel-xen* | xargs rpm -e

vi /etc/grub.conf
look for the kernel line and remove the following
console=xvc0
so the line looks something like
kernel /vmlinuz-2.6.18-164.6.1.el5 ro root=/dev/sdb1

vi /etc/modprobe.conf and remove any lines with xen in them ie:
alias scsi_hostadapter xenblk
alias eth0 xennet

now to leave the chroot type in:
exit
and to finally restart your client
reboot
allow selinux to fix the filesystem and auto reboot

once you confirmed your machine is up and running fine shut it down and power off the vm and remember to detach your cdrom from the client.

bootup your system
right mouse click on the vmware machine and select guest -> install/upgrade vmware tools
click on ok
type in dmesg and you should see the last drive attempting to connect example hda
type in:
mount /dev/hda /mnt
now copy the tools to your root directory
cp /mnt/VMwareTools*.tar.gz ~/
unmount the tools
umount /mnt
extract the tools
tar -zxvf VMwareTools*.tar.gz
change to the proper directory
cd vmware-tools-distrib
then run the installer
./vmware-install.pl
just choose the defaults for all the questions
once the installer completes run the optional vmxnet driver
/etc/init.d/network stop
rmmod pcnet32
rmmod vmxnet
modprobe vmxnet
/etc/init.d/network start

remove the /etc/yum.repos.d/Citrix.repo
and run a yum update

Dell r410

Paul — Thu, 17 Dec 2009 01:12:13 +0000

Never buy a Dell r410 without the hot swap option. The drive bays are only removable if you take the cover off of the server due to a retaining clip at the back of the hard drive sled.

Openfire Admin Password Reset

Paul — Tue, 08 Dec 2009 23:22:03 +0000

First check your openfire.xml file located in your conf directory (example: RHEL5 is /opt/openfire/conf).

Look for the lines to give you the server’s address, database name, username and password to authenticate with.

com.mysql.jdbc.Driver
jdbc:mysql://localhost:3306/openfiredb
openfire
L0t0!
select 1
true
true
5
15
1.0

If your using the internal MySQL authentication like this example you can connect to the database via this command

mysql -u openfire -p openfiredb

Then use the password L0t0!

When your connected to the database run the following command to reset your admin password to 123456

update ofUser set plainPassword=’123456′, encryptedPassword=NULL where username=’admin’;

Now restart your Openfire server(example: RHEL5 run /sbin/service openfire restart) and you should be able to login via the admin page with the username admin and password 123456.

vSphere + ESXi4 SSH Tunnel

Paul — Thu, 03 Dec 2009 22:39:04 +0000

In order to use vSphere properly over a SSH tunnel forward the following ports

If you still cannot connect with vSphere to your remote machine update your hosts file. For example, if your ESXi 4.0 server is named vmsrv1 edit your hosts file:

127.0.0.1 vmsrv1

With Windows your hosts file is located in C:\Windows\System32\Drivers\etc and under Linux /etc/hosts

From Wikipedia

A batsu (punishment) game that took place over the period of 24-hours, where all, except Matsumoto, were locked in a sports arena, playing “tag” with various Oni (demons) who were men dressed in full-body black suits, were “summoned” to attack at random moments, each with a specific type of punishment written on the suit to be inflicted whenever the victims were tagged. This batsu game is the result of Matsumoto winning the race against the 4 others in “Gaki no tsukai – 4 tai 1 100m sou Taiketsu!”
