LDAP-Authenticated Server & Whoami Failures (etc)

I’m back again, after a bit of a unscheduled ‘break’ in my normal work life.  After a couple of days away for work on the Gold Coast, then the sad passing of my Grandfather and his memorial, then being sick over the last weekend from what I can only guess was a nasty 24-hour bug, I’m back.  And whilst a little worse for wear still today, it’s life pretty much as normal.

Today’s fun and games was on a server we use that uses LDAP authentication for its users.  Nothing special, except that today I started …

Buildout: the biggest problems have the simplest answers…

..and how true that is.  Today’s time consumer is directly related to just 1 misplaced line of a buildout configuration (and presumably something that’s changed somewhere else).

The result

After much hunting and hunting, it turns out my Zope2 Fake Eggs weren’t being generated.

On my long quest I had to go through downloading new packages and trying to find something that had changed and even trying to establish new virtual environments on different VMs.  Nothing would fix the problem. To rub salt in the wound, my desktop Ubuntu ran the buildout fine, so methinks the underlying …

Virtualenv, Plone, and Centos 5.x

EDIT: Watch out for python-ldap 2.3.10, the latest version at time of writing. Seems like there’s an issue with it and Centos 5.4. Forcing python-ldap to be version 2.3.8 works, though. (easy_install python-ldap==2.3.8)

Previously, you might have read about setting up a Virtualenv on Ubuntu Jaunty. Now, that was reasonably painless since python-virtualenv and python-setuptools is in the Ubuntu repo. Whether it’s my Centos servers and their misguided repos or me just not being able to find such a related rpm packages, Centos just needs little more love to get …

Unix: Removing Open Logical Volumes in Centos/RHL

Because I still haven’t remembered to set myself up with a limited-access account for blogging on my new site, I’m back here again. (EDIT: Migrated from old site)

This time is a lot of fun and games with removing an “open” logical volume from within a CentOS environment. The dom0 machine has a set of logical volumes in a volume group for each of the VMs and one of them went and failed dismally, and after its xen destruction (xm destory foo) its LV was left with it being “open”.

It’s not exactly easy to see how …
