forwarding GRE traffic di router palugada

20 03 2010

Memakai linux untuk router palugada? (ISR in cisco marketdroid speak, router sekaligus firewall, bw manager, proxy, dll )
Problem ketika melewatkan traffic GRE? (padahal rule netfilter sudah accept semua)
Routernya melakukan NAT? atau mangle packet? atau PBR?
Coba aktifkan modul2 kernel yang ditemukan dari command find /lib/modules/`uname -r`/ -name ∗gre∗
Semoga jadi solusi :-)


On migrating tasproject's sites from apache2 to nginx

06 03 2010

Some notes:


  • nginx can run php via fastcgi
  • migrating serendipity to nginx is pretty easy, just google 'serendipity nginx', and you'll get howtos on additional rewrite config needed for serendipity.
  • Dokuwiki doesn't need any additional rewrite configs
  • in progress: migrating MovableType
  • nginx install & config notes coming soon! :-)

Network outages: the biggest cause

the biggest cause of network outages is not hardware or software failures, it’s folks making configuration changes.

Indeed Sir! :-)


Finally, conquering the .ithmb file

18 09 2008

I have one .ithmb file copied from ratugalak's ipod months ago. This file was an 'unfinished business', left over from a quick tinkering session when i tried to use Linux to read/write ratugalak's 6th gen iPod Classic.

The original intent was copying photos from iPod to Linux (Ubuntu Edgy). I tried gtkpod, gpixpod and few other application, but all failed. Apparently the 6th gen was not yet supported at that time. Linux was able to access and read iPod's filesystem, but unable to 'translate' ithmb files as graphic files. So, after quick observation (and little checking with file and strings), i copied the biggest .ithmb file to my harddisk, promising myself that i'll read the contents of this file someday. Using Linux!

The victory day finally come! After a day of unproductive activity (procrastination, blogwalking, yada-yada), I stumbled upon a forum thread, discussing very same problem i have: How to read .ithmb file (this thread starter is using Windows though). The answer : use iThmbConv.exe. This windows command line app (ha!) will read .ithmb file and translate it into .ppm files.

So, i downloaded the .exe file and ran it with wine. The result: 759 .ppm files extracted from a 500MB .ithmb file. Problem solved, at last :-).


another wordpress blog

16 09 2008

Couple days ago friendster informed their users about new blog URL. Well at that time i couldn't see what's changed, because the URL failed :-D. But today, when i randomly blogwalking to some friends friendster blog, i see a familiar appearance: The Kubrick template!
Soo now friendster is using wordpress for the blog engine, replacing the old and (t)rusty typepad. Congrats to wordpress (and matt ;-) ), another step to world domination.
I personally wondering about the migration process, sounds 'trivial', dumping typepad's post table data and import them to wordpress' db (or, changing the table schema perhaps), but then if we consider the number of account friendster needs to convert, that would be interesting. Hmm.. time to googling, maybe someone already blogged about it
