Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

Stupid little konsole trick

Ok, so I have a dual-head setup at work (running OpenBSD-4.6), and I am usually ssh'd into dozens of machines at a time. My desktop tends to look like a fuster-cluck of aterms.

So I discovered a cool little trick with konsole. Using dcop, you can open new terminals as a new session (tab) in an existing konsole window and then send commands to said sessions (and even rename the sessions to match what commands you sent to it).

But, there's only one problem. I'm running...

PostgreSQL - installation/configuration/benchmarking - on Dell servers Part II

(Continued from this blog post)

Now test the setup:

Code:
linux ~ # hdparm -tT /dev/sdc

/dev/sdc:
 Timing cached reads:   11464 MB in  2.00 seconds = 5739.66 MB/sec
 Timing buffered disk reads:  1816 MB in  3.00 seconds = 604.39 MB/sec
Looks good. Now let's format the partition:

I like xfs. I use xfs. You might not...so run "man mkfs.<your_favorite_filesystem>" to read up on how to convert...

PostgreSQL - installation/configuration/benchmarking - on Dell servers

Dell has historically had a pretty low-end line of RAID cards (the PowerEdge Expandable RAID Controller, or PERC for short) that have required tons of time and care to get them operating at a reasonable level. This blog post will cover my experiences with the PERC6/E line of cards (which aren't that bad, especially compared to previous versions) and how to get optimal performance out of them on Dell 1950/2950 machines, as well as PostgreSQL general configuration.

Remote management of Linux systems via Python and ssh (Part 2)

Posted 02-03-2009 at 08:44 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)
Updated 10-27-2009 at 06:50 PM by rocket357 (modified code)

My last blogpost on Python/SSH seemed to be popular, so here I am again with a more in-depth look at what can be accomplished with this pairing.

To recap, I manage 300 databases, some M$ SQL Server, some PostgreSQL. There are a ton of Apache/Linux machines on our network and quite a few "traffic cops" based on Linux and BSD (as well as a few Cisco machines) for routing external traffic to internal machines. Pretty standard stuff. The IT department has a director, a network...

Thoughts on problem solving for new Linux users

Posted 02-02-2009 at 12:40 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

One of the hardest issues to grasp for many Linux newbies is not a Linux issue, rather it's their problem-solving approach. With the closed-source Windows business model, you really only have one problem-solving option available: tech support. While members at sites such as LQ do their very best to provide something like tech support, there really is a lot more that newbies can do to speed up both their understanding of Linux and finding a solution to whatever problem they're looking at right...
