While re-purposing a few old Google Search Appliances I set up a Network Boot Enviornment as follows: Install Dependencies yum install tftp-server tftp syslinux httpd dhcp Configure tftp mkdir /tftpboot vi /etc/xinetd.d/tftp service tftp { socket_type = dgram protocol = udp wait = yes user = root server = /usr/sbin/in.tftpd server_args = -s -v /tftpboot… Read more »
I have three main proxy servers running Squid, Squidguard and DansGuardian servicing over 1300 desktop computers. The stock DansGuardian code includes a setting to limit the number of potential DansGuardian child processes to the operating system file descriptor limits. I have managed to increase this to 900 but would like to push it further. The setting… Read more »
I have a PHP web application that communicates to Windows Shares via the smbclient binary. My problem was that some characters (particularly accented characters such as é ) were not being shown on the PHP page and were even causing lines of output to be omitted. After ensuring the PHP page was outputting UTF8 I… Read more »
I ordered a CoolerMaster Hyper 212 Evo from Amazon for £26.50 to keep my machine a little cooler than the stock heat sink. The two heat sinks are shown below. The CoolerMaster is much bigger and could be a struggle to get in to most cases but I am very happy with the results. It… Read more »

I started exploring how I could script the creation of this when I happened upon WP-CLI. yum install git Then… Read more »
My colleague forgot the password he used for the admin user account on the RSA Security Console – since it needs to be changed and a previously used password cannot be re-used. We have it installed on a Windows Server 2008 so to create a temporary admin account: Open Command Prompt Change directory to the… Read more »
Install with: sudo apt-get install mediatomb Amend the /etc/mediatomb/config.xml file. I find the configuration below works well for all the video types I throw at it.

To prepare to test a TLS connection to an SMTP server we first need to Base64 encode the Login credentials: perl -MMIME::Base64 -e ‘print encode_base64(“\000LoginID\000password”)’ The result of this is: AExvZ2luSUQAcGFzc3dvcmQ= I tried using the base64 linux command but did not get the same result or a result that would work: echo -n “\000LoginID\000password” |… Read more »
When using XBMC we usually use the ‘Files’ menu. The folder icons under ‘Files’ do not show a preview thumbnail unless there is an image in the folder named ‘folder.jpg’. I could manually search for folder images for each movie but decided that would be time-consuming so I put together a wee PHP script –… Read more »
We had a bit of difficulty yesterday with LDAP / Active Directory authentication within Exim. Sending mail via SMTP with authentication was timing out and it looked like a TLS error. 2013-10-01 14:39:12 [17013] TLS error on connection from blahblahblah (ehloname) [192.168.1.3]:52031 I=[192.168.6.51]:587 (SSL_accept): error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol We got to the bottom of the problem… Read more »
