Be the automator!

Today I saw an awesome video of a presentation by Glenn O’Donnell. In his presentation, Glenn states that it’s not about technology, it’s about services. Service design is modular with a logical structure. Approach it as a system and try to improve it as a whole, not just tiny pieces of it. To do that, […]

Phasing out legacy command line options

For historical reasons, rsyslog offers a number of command line options which are actually configuration settings. These stem back to the days of the original syslogd, where the conf file was just a routing table and "all" other configuration was done via the command line. Some of them (e.g. -r to enable listening to the standard UDP port) have already been removed quite a while ago. Now, we are very serious about removing the rest of them.

Understanding Formatted Capacity versus Unformated Capacity

Have you wondered why Formatted Capacity is lesser than the Unformated Capacity of a Hard Disk. Do take a look at this article Formatted capacity confusion clarified
Storage hardware is using the base 10 system and software is using the base 2 system. So no storage is actually lost, it is just a question of how the information is represented.

PXE booting for Oracle Solaris using Windows DHCP server

A quick blog entry about getting Solaris PXE boot working with Microsoft Windows DHCP server. I was always told it was easy but I never managed to get it to working even though a lot of people I talked to had it working.

The problem was that our network was not correctly configured for PXEbooting. Problem was our network need PortFast enable (Good Ref: Spanning Tree Protocol (STP) and PortFast).

Ansible – disable gather facts

 
When we execute an ansible playbook by default it will gather facts of operating system first and then execute tasks listed in it.
Its always not required to gather facts & if we have too many hosts it will take more time to execute a playbook.
To mitigate this we need to disable gather facts with “gather_facts” attribute in ansible playbook.
By default gather_facts attributes value is True, to disable it we need to set it as False.
gather_facts: False
Here is my play book example with gather_facts: False
