I decided to do a bit of checking on the proxy.pac file we were using. I grepped through our Apache access log files to pull out all of the IP addresses accessing the file over the year: zgrep “proxy.pac” ./2013-??-??.access_log.gz | awk ‘{print $1}’ | awk -F “:” ‘{print $2}’ | sort | uniq >… Read more »

MS SQL Server Monitor Queries

To analyse the type of SQL queries received by the server I used ‘SQL Server Profiler’ as follows: File > New Trace … Connect to the database if… Read more »
Radius with LDAP Authentication
The notes here are a quick howto for using LDAP authentication against Active Directory.

Install required software on CentOS/Red Hat: yum install freeradius… Read more »
Apache Directory Studio (Softerra Alternative)

[global] workgroup = WORKGROUP server string = %h server (Samba, Ubuntu) dns proxy = no log file = /var/log/samba/log.%m max log size = 1000 syslog =… Read more »
Twiki Installation and Setup Overview
I am not necessarily a fan of this software as I find it a bit less than intuitive to use but I set it up on one of our CentOS servers for someone else and thought I would jot a few notes about the process. Install dependencies: yum –disablerepo=rpmforge –enablerepo=epel install httpd gdal-perl perl-CGI perl-CGI-Session… Read more »
