Dependency hell

2006-08-23 14:37:00

Damn! I'm really starting to hate Dependency Hell. Installing a few Nagios check scripts requires the Perl Net::SNMP module. This in turn requires three other modules. Each of these three modules requires three other modules, three of which require a C compiler on your system (which we naturally don't install on production systems). And neither can we use the port/emerge/apt-get alike Perl tools from CPAN, since (yet again) these are production systems. Augh!

Building RPM packages

2006-08-10 13:48:00

While working on the $CLIENT-internal package for the Nagios client (net-SNMP + NRPE + Nagios scripts + Dell/HP SNMP agent), I've been learning about compound RPM packages. I.e., packages where you combine multiple source .TGZs into one big RPM package. This requires a little magic when it comes to running the various configure and make scripts. Luckily I've found two great examples.

* SPEC file for TCL, a short SPEC file that builds a package from two source .TGZs.

* SPEC file for MythTV, a -huge- SPEC file that builds multiple packages from multiple source .TGZs, along with a very dynamic set of configure rules.

SANE 2006 conference notes

2006-08-09 07:35:00

After months and months I've uploaded the notes that I took at the various lectures at SANE 2006. They might be usefull to -someone- out there. Who knows. Be aware though that portions of the notes are a mishmash of dutch and english :) The notes can be found as .PDFs in the menu on the left.

Listen up. Here's da plan...

2006-08-08 16:52:00

Because I've got all kinds of things lined up for me to do, I'm going to put them into order. That way both you and I will know what to expect. Here's my priorities:

1. Make the requisite changes to my website, so that it plays nicely with search engines. This shouldn't be more than an evening or two of work (barring any reruns of Doctor Who on BBC3).

2. Study for my two LPIC1 exams.

3. Revive the manga and anime section of the website. This needs regular updates, so I'm going to have to think of a few nice things to add to this. I'm thinking "reviews"... It's also meant to give me a couple of days off between studying for my four exams.

4. Study for my two LPIC2 exams.

5. Move other parts of the website into the mySQL database as well.

6. Improve the PHP code that gets data from the database. It could be much cleaner, safer and efficient.

7. Build some form of CMS for myself, so I don't have to work in the database manually.

So there you have it boys! The next few months of my life lined out for ya.

Parallel to da plan I will keep on expanding the Sysadmin section with new stuff I discover every week. And I will try to fit in a week or two of vacation somewhere along the line. I have a big bunch of video games that I finally want to finish!

Creating packages

2006-08-08 11:04:00

Recently I've been trying to learn how to build my own packages, both on Solaris and on Linux. I mean, using real packages to install your custom software is a much better approach than simply working with .TGZ files. In the process I've found two great tutorials/books:

* Maximum RPM, originally written as a book by one of Red Hat's employees.

* Creating Solaris packages, a short HOWTO by Mark.

SNMP = hard work

2006-08-01 17:23:00

Boy lemme tell ya: making a nice SNMP configuration so you can actually monitor something useful takes a lot of work! :) The menu on the left has been gradually expanding with more and more details regarding the monitoring of Solaris (and Sun hardware) through SNMP. Check'em out!

All work and no play...

2006-08-01 11:49:00

Busybusybusy, that's what I've been. I've been adding all kinds of new stuff to the Sysadmin section, telling you everything you'd like to know about monitoring Solaris and Sun hardware through SNMP.

I don't have much interesting to tell to the non-admin people right now :) Better luck at a later point in time.
