Opening Message

Hello and Welcome!

Over the course of my time as an Admin I've done a lot of Google searches and writeen a lot of code that has been very helpful to me in my work. I will be posting things here that hopefully will help you in your quest to master some of these technologies (Or simply stand on the shoulders of midgets).

I by no means consider myself a Perl or LDAP expert. It has been a "Learn as you go" ordeal. No formal training, just get things done on an as-needed basis.

I assume that you have a basic knowledge of PERL and LDAP.

Enjoy!

-Sean

OUCH!

[music | The Pixies - Break My Body]

If you'll remember back a few months, I lost a toenail after catching a drunken pit guy at Rev. Horton Heat. In today's installment, it's a fingernail.

Today I was putting some switches in a rack, and was putting in cage nuts the un-safe way. With a screwdriver instead of a cage nut tool. Here's what the aftermath of that can look like unless you're more careful than I am.

I'm putting pictures behind here for people who are queasy:

CSSManager

The CSSManager is meant to allow access to certain functions of the Cisco CSS series load-balancers to less trusted (non network-engineer) staff without opening the CSS up to too much risk of misconfiguration. Currently it allows web users to suspend and activate Services in bulk quickly and safely. There are also value-added features such as "locking" servers so someone can't accidently activate a server that was suspended for a reason, comments are also useful, especially when used in conjunction with CSSPump to give context to a suspended or down server.

Tools and Hacky Stuff

Here are some tools I've written which could be of use to other folks. It's going to be mostly Cisco related, some of which is still being formatted before I upload it, more to come.

CSSManager is a tool to simplify suspending and activating services in a Cisco CSS load balancer. It adds a couple of features like the ability to "lock out" a server and to add comments to a suspended machine to give context for its suspension. More features to come.

Cisco CSS Toy

[music | Bauhaus - Dark Entries (Live)]

This is the first of a few tools I have to release in the coming couple of weeks, mainly involving Cisco's CSS product. The purpose of me writing them is that Cisco's web interface to the CSS is both a terrible user experience and has shown itself to be vulnerable to trivial attacks in the past (in a security sense). I don't want to run the web gui on my CSS's, and most of our admins were terrified of the command line. So I wrote a bunch of tools to help do their jobs, without the possibility of screwing up the load balancers.
