I am working on some client-side Javascript and I need to be able to test it in all of the currently extant versions of Internet Explorer. A collegue of mine pointed me to the ievms project by Greg Thornton (xdissent) that automates the download of multiple Windows vms provided by Microsoft to facilitate testing in multiple versions of IE.

To get it working under Fedora (RedHad, CentOS):
. The script requires unar but is not readily available for FC18. → Continue reading “Automate the Download of Windows VMs for Testing IE6, IE7, IE8, IE9, IE10 and IE11 with ievms”

I am setting up a cluster of KVM virtual machines and want to be able to ssh to them as the root user on the vm without having to enter a password.
The first thing that I did was create keys on the box from which I was going to make connections (A):
[rchapin@A .ssh]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/usr/local2/home/rchapin/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again: → Continue reading “Setting Up Passwordless SSH Under CentOS 6 Running Selinux”

Most high level languages have some sort of String.split([delimiter]) method to create an array of Strings tokenized by a user specified delimiter. This is a simple way to convert a CSV into an array.
Here is a quick way to do that in a bash shell script:
#!/bin/bash
SOURCE_STRING='foo|blah|moo'
# Save the initial Interal Field Separator
OIFS="$IFS"
# Set the IFS to a custom delimiter
IFS='|'
read -a TOKENS <<< "${SOURCE_STRING}"
for i in "${TOKENS[@]}"
do
echo "$i"
done
#
