A Recent Eclipse On Debian

Posted by coldtobi | 9 May, 2009, 13:58

Eclipse is WAY outdated on debian. Even the unstable release ships a basically unmodified version since 3 years.

So today I decided to remove the ancient version -- which did not start anyway -- and try the new nice release from eclipse.org:

And, hey... It works like a charm. The only downside is, that it will run in a local directory in your home directory. But that could be fixed my installing in /opt and including it into the default path.

Manually upgrading horde3 on debian

Posted by coldtobi | 19 Feb, 2009, 00:15 Debian is currently in freeze. (As finishing this, debian just released Lenny!) As a consequence many packages are quite outdated.

For example, the horde framework I use on my NAS is quite old and misses some features I'd like to have.

However, there are some pitfalls when using the debian version and trying to update with the upstream version, as the "debian way" stores some files at different locations, which is ok.

Thecus N2100: Testing a new kernel. Or the Installer. Or Revert. Or Recover.

Posted by coldtobi | 15 Aug, 2008, 10:09

Because of personal experience, it is good to test a kernel prior flashing it: It ould happen, that the Thecus won't boot with a new kernel. I learned this the hard way.

But how to test it? The trick is, to the kernel into RAM and execute it from there.
This howto will show all the steps necessary to testdrive a kernel.

By the way, these instructions are also good for other uses: For example,

  • if you need a recovery/rescue system, (the debian installer is fine for that purpose.)

  • if you prefer to run the debian installer from RAM, (for tests, or if you don't wan't to reflash your current firmware)
  • if you want to uninstall debian and revert to the original firmware.
  • have a backup-kernel handy. ("Known-Good-Kernel")

Best of all, this is done completely in RAM. So just "pull the plug" to revert to the old state.

Update: Please also read this article for some updates. (More)

How to check if you have ModRewrite

Posted by coldtobi | 12 Jul, 2008, 18:58

ModRewrite comes handy for SEO and other opportunites, where you want to change URL to something else. Lifetype uses this to assemble all the php parameters and make more search-engine and humanfriendly URLs. Also, you can do the RFI Protection I described earlier.
To find out, whether your webhoster's Apache supports ModRewrite, you have basically two options:

[Links] Version Control Systems -- Comparsions

Posted by coldtobi | 22 May, 2008, 11:55
For some of my personal data, I currently use CVS. But as this task also should go tho the Thecus, I was looking for something more mordern.

And, there are a lot of them, to many to take a look at them indivudually. Lucklily, other people did that already, so if you ara also in a simular situation -- choosing a new or replacment CVS System (or also called SCM, Configuration Managment ...)

Well, however you wanna call it, here are some links articles to check out:
The New Breed of Version Control Systems
Better SCM Initiative : Comparison
Version-Control Systems for Linux
(As far as I am through with that links, montone looks very promising as is currently my top candiate)

Debian OpenSSL vulnerability: Check your installation/keys

Posted by coldtobi | 14 May, 2008, 09:57

As I learned today by an announce at the debian security list, there was a "patch" against security in the OpenSSL Library. The patch is debian specific, so applies only to debian and clones (e.g Ubuntu). However, it was sufficient to create the keys on a affected machine, so everyone could be affected, if the keys where transfered to a third machine.
