BackTrack Remove disks or other media

After creating a bootable USB image for BackTrack 5 R3 with Unetbootin you may encounter an error:

[code]
Remove disks or other media
Press any key to restart
[/code]

This means you have incorrect image on USB drive.

Simple solution is to use a different ISO to USB utility:

You can download it from following URL:

Universal USB Installer – Bootable Pendrive Software

Ansible No Package matching found available installed or updated

When trying to manage packages with yum module via Ansible, on fresh installed RHEL / Centos Linux systems, you may face following error:

[code]
msg: No Package matching ‘sendmail-cf’ found available, installed or updated
[/code]

This is caused by missing package yum-utils.

It can be installed with Ansible raw module (also used for installing python-simplejson for Ansible):

[code]
ansible 1.2.3.4 -m raw -a “yum -y install yum-utils” –user=userx –sudo
[/code]
