The backups you never make

Anders — Thu, 18 Jan 2007 06:23:08 +0000

So my harddrive for my home-server crashed. Seems like it short-circuited or something. Any tips for restoring would be appreciated. I had devised some sort og backup mechanism, that obviously didn’t work. Lost about a years worth of posts.

Have signed up to Dreamhost now which offers 200GB diskspace on the cheapest plans. Finnally we are seeing hostingplans that are viable for my hosting. My first impression of their controlpanels etc. are really good too. Some minor glitches, but seems like a well thought through product.

UPDATE: Think I retrieved most my content from some caches. It’ll be a fair bit of job to put it back into wordpress, but at least it’s not lost.

Cleanup directory

Anders — Mon, 18 Dec 2006 16:52:39 +0000

So we started running Maven snapshots at a fairly regular basis to enable automatic running of Watir tests. This fills up the disk really fast so I had to do some research to fine a linux command that would delete all but the newest snapshot from multiple projects:

find /var/www/maven2-snapshots -type d -path '*SNAPSHOT' | xargs -i bash -c "find {} -type f -not -path '*maven-metadata*' | grep projectname | sort -r | awk 'NR>6'"

The above command will keep everything that is called maven-metadata something and the 6 latest files in the directory (Maven generates 6 files for each snapshot).

I need this tutorial next time.

Oracle XE on Linux

I’m not a big fan of Oracle. I’ve had my fair share of problems with their products, but I’ve mentioned before that I think they’re on the right track. As one example you now got deb packages for Oracle Express Edition. Check out a tutorial here.

Update: Another blog that also includes some details about environment and user creation here.

The final steps of installing D-Link DWL-G520+ on Fedora Core 5

Øyvind — Wed, 14 Jun 2006 19:58:59 +0000

This is how I installed my D-Link DWL-G520+ wlan card on Fedora Core 5 (FC5). This card has Texas Instruments chipset and needs the acx111 driver.

Follow the instructions found at the acx100.sourceforge.net homepage.
Add “alias wlan0 acx” at the botom of the file /etc/modprobe.conf
Check that “chkconfig --list NetworkManager” says “ n” under runlevel 3 and 5
If not execute “chkconfig --level 35 NetworkManager on” and check again.
Run “depmod -a“
Restart the computer. (I do not think have to do this, but you’ll never know.)
You should now be able to see your wlan card in the GUI-based Network Configuration tool found under System->Administration->Network (in KDE.. Will swich to Gnome soon).

This is what did the trick for me and I think i have remembered everything. I used kernel 2.6.15-1.2054_FC5-i686 and driver version acx-20060521. Well, no that I am onlie i should upgrade my system and do it all over again with the newest kernel ang gnome.. I’ll update this post if I find any major differences.

Good Luck!

I knew this, but got reminded when I stumbled over this page at VMWare. They have released their VMWare player for free, and there are a bunch of Linux images available here. Downloading my trusty old Debian as well as Ubuntu and Fedora right now. Thought I’d just check out how they were coming along. As if I didn’t have enough other stuff to do.

Oh yeah, and this BEA WebLogic image should probably be a good kickstart for development with BEA.

This page explains how to do a binary upgrade from FreeBSD 5.3 to 5.4 using freebsd-update.

Looks easy and i will give it a try..

Here are some of my most frequently used links regarding FreeBSD. They will help you out with most of the basic questions (and some advanced too).

Apache – “Client denied by server configuration” tips

Øyvind — Wed, 01 Jun 2005 22:53:46 +0000

Having problems with displaying your site and getting error 403 in your web-browser?

does the log-file for apache errors contain lines like tis?
“client denied by server configuration: /path/to/files”

Then you probably have denied access to the directory in the httpd.conf file.

Allow access by adding:

allow from all

If your are using VirtualHosts then add the directory-block inside the block.

FreeBSD thread started!

Hi folks!
I’ve just installed FreeBSD for the first time and plan to share the findigs that I do here on on this page.

I’m a rookie at the time being, but hope to advance into an expert as time passes. Well, atleast intermediate;)

Serverspec:
Pentium III 800MHz
256MB RAM
1 x 17GB SCSI
2 x 80GB IDE

Nothing much, but it does the trick
