Rebuild locale on Linux

Posted 01/10/2014 by Chris & filed under Linux & Unix.

A quick note on how to rebuild Linux locale, you might get the following errors if your locale is broken:

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

locale: Cannot set LC_CTYPE to default locale: No such file or directory

locale: Cannot set LC_MESSAGES to default locale: No such file or directory

locale: Cannot set LC_ALL to default locale: No such file or directory

To find out what locale is set, run the following:

locale

locale

Output should be something like this:

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_AU.UTF-8
LANGUAGE=
LC_CTYPE=&quot;en_AU.UTF-8&quot;
LC_NUMERIC=&quot;en_AU.UTF-8&quot;
LC_TIME=&quot;en_AU.UTF-8&quot;
LC_COLLATE=&quot;en_AU.UTF-8&quot;
LC_MONETARY=&quot;en_AU.UTF-8&quot;
LC_MESSAGES=&quot;en_AU.UTF-8&quot;
LC_PAPER=&quot;en_AU.UTF-8&quot;
LC_NAME=&quot;en_AU.UTF-8&quot;
LC_ADDRESS=&quot;en_AU.UTF-8&quot;
LC_TELEPHONE=&quot;en_AU.UTF-8&quot;
LC_MEASUREMENT=&quot;en_AU.UTF-8&quot;
LC_IDENTI

locale: Cannot set LC_CTYPE to default locale: No such file or directory

locale: Cannot set LC_MESSAGES to default locale: No such file or directory

How to Upgrade Cisco Flash Firmware Version

Posted 26/09/2014 by Chris & filed under Cisco.

I recently had to upgrade a Cisco router to a new firmware version, so I thought I’d write up a quick how-to guide.

Prerequisites:

Download the new flash version from Cisco (you need a valid Cisco login)
TFTP the firmware to the Cisco device
Connect to the Cisco device using a console cable (highly recommended!

1. Log into the router
2. Elevate to enable

enable
&lt;password&gt;

1 2	enable <password>

3. Check to see if the flash is in the correct location

dir flash:

1	dir flash:

4. Enter configuration terminal

config term

1	config term

5. Disable current flash

no boot system

1	no boot system

6. Specify flash file

boot system flash: &lt;fullfilenameplusextension&gt;

1	boot system flash: <fullfilenameplusextension>

7. Exit out of configuration terminal

exit

exit

8. Display the version

show version

1	show version

If the last digit in the configuration register is 0 or 1 the n go to next step however if the last digit in the configuration register is between 2 and F then proceed to step 12

9. Enter configuration terminal

config term

1	config term

10. Run config-register command

config-register 0x2102

1	config-register 0x2102

11. Exit out of configuration terminal

exit

exit

12. Copy the running to startup

copy run start

1	copy run start

13. Restart the Cisco device

reload

reload

When prompted to save the configuration, enter no

When prompted to confirm and reload, enter yes

If the router reboots and then reboots again straight away, it has not worked and has reverted back to the last firmware version

If it simply reboots, log in and check the version

show version

1	show version

Citrix XenApp: Event 10001 – A usable server cannot be found on which to launch the application. Check your worker group definitions and load balancing policies to verify appropriate servers are assigned

Posted 23/09/2014 by Chris & filed under XenApp.

After rebooting my Citrix XenApp server, I was presented with an error in the application event log for the Citrix application stating the following: “A usable server cannot be found on which to launch the application. Check your worker group definitions and load balancing policies to verify appropriate servers are assigned”.

Details blanked out to protect the innocent

After doing a lot of Google searching, I came across a forum with someone with the same problem, to verify the issue I ran the following command:

qfarm /load

1	qfarm /load

It gave me a result of “1000” which apparently isn’t right

So to resolve this issue you have to rebuild the perfmon counters, in my example I am using Microsoft Windows 2008

lodctr.exe /r

1	lodctr.exe /r

If you need to rebuild the counters for Microsoft Windows Server 2003, see this article here

Additionally, you will find a summary of what the qfarm values are here:

0 to 9998 = This is a normal range for the load manager
99999 = No load evaluator is configured
10000 = load is at 100 percent (full)
10000! = Application disabled for this server
10001 = Out of licenses
10002 = No ICA connections are available for that server
20000 = Incorrect server edition or a license mismatch
99990 = No permission to run qfarm

It fixed the problem for me, hopefully for you too.

Enable SNMP Traps on a VMware ESX 5.1 + Physical Host

Posted 17/09/2014 by Chris & filed under VMware ESX.

I reinstalled my VMware ESX servers the other month and haven’t got around to setting the SNMP traps back up for Observium to use so I thought I’d make a quick article to show how it is done (as I had to look it up again).

1. Log into the console or shell to the box

2. Run the following command to set the trap name (Replace TRAPNAME with the community name you use)

esxcli system snmp set --communities TRAPNAME

1	esxcli system snmp set --communities TRAPNAME

2. Enable the trap

esxcli system snmp set --enable yes

1	esxcli system snmp set --enable yes

3. Log into vSphere

4. Select the host

5. Select the configuration tab

6. Select Software -> Security Profile

7. Under Firewall, click properties

8. Find the SNMP Server under label

9. Go into the options of the service

10. Change to “Start and stop with host”

11. Click on Start

Your traps should now be working

Installing Piwik for Website Visitor Tracking on Apache

Posted 12/09/2014 by Chris & filed under Piwik.

Okay so I have been using Piwik for about a year now and find it to be flawless so I thought I’d do a write up about it.

From the Piwik website: Piwik is the leading open source web analytics platform that give s you valuable insights into your website’s visitors, your marketing campaigns and much more, so you can optimize your strategy and online experience of your visitors.

Installing

Assumptions

This is assuming the following is already configured:

A valid public domain
The said public domain has A records pointing to a publicly visible Apache web server
The said Apache web server has a valid vhost configuration for said domain
The said Apache web server has PHP 5.5 or greater installed and working
The said Apache server has internet access to download files
The said web server has mySQL installed and configured correctly

Configuring Apache

Create a directing for the Piwik install, I will be using example.com as an example domain

mkdir -p /var/www/vhosts/example.com/piwik

1	mkdir -p /var/www/vhosts/example.com/piwik

Download Piwik

cd /var/www/vhosts/example.com/piwik
wget http://builds.piwik.org/piwik.zip

1 2	cd /var/www/vhosts/example.com/piwik wget http://builds.piwik.org/piwik.zip

Install Unzip (if not installed)

apt-get install unzip

1	apt-get install unzip

Unzip the contents of the zip file

unzip piwik.zip -d ../

1	unzip piwik.zip -d ../

Change ownership and permissions

chown -R www-data:www-data /var/www/vhosts/example.com/piwik
chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp
chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/assets/
chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/cache/
chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/logs/
chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/tcpdf/
chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/templates_c/

chown -R www-data:www-data /var/www/vhosts/example.com/piwik

chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp

chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/assets/

chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/cache/

chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/logs/

chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/tcpdf/

chmod -R 0755 /var/www/vhosts/example.com/piwik/tmp/templates_c/

Configuring mySQL

Note1: Do not use the “mysql>” at the beginning of the command, that is just to indicate you are in mysql command prompt.

Note2: mySQL commands require a “;” at the end of the command

Log into mySQL

mysql -u root -p

1	mysql -u root -p

Create a new database

mysql&gt; CREATE DATABASE piwik;

1	mysql> CREATE DATABASE piwik;

Use the database

mysql&gt; USE piwik;

1	mysql> USE piwik;

Create a user

mysql&gt; CREATE USER 'piwik'@'localhost' IDENTIFIED BY 'password123';

1	mysql> CREATE USER 'piwik'@'localhost' IDENTIFIED BY 'password123';

Grant permissions for the piwik account to the piwik database (don’t use password123)

mysql&gt; GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON piwik.* TO 'piwik'@'localhost' WITH GRANT OPTION;

1	mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON piwik.* TO 'piwik'@'localhost' WITH GRANT OPTION;

Finish Install

Browse to the Piwik installation using your browser (I am using example.com)

Select “Next”

Make sure everything has green ticks next to them and click “Next”

Leave the database server as 127.0.0.1

Type in the username

Type in the password

Type in the database name

Select PDO/MYSQL

Click “Next”

Ensure tables are created and click “Next”

Type in the desired admin login name, password and email address and press “Next”

Type in the website name, URL, time zone and whether or not it is a ecommerce site or not and then press “Next”

Take a copy of the Javascript tracking code and select “Next”

Click on “Continue to Piwik” to continue

If prompted, upgrade database

I recommend donating using the secure PayPal feature, select “Continue to Piwik”
