Migration Debian from i386 to amd64 without reinstall (Cross Grading)

Posted by coldtobi | 2 Nov, 2013, 14:53

Well, I just started the adventure to upgrade my NAS server from i386 to amd64.. Why? I want to enable flash-cache, which is currently not compatible with 32-bit kernels.

For this I am using the "Cross Grading"

Note: This is dangerous stuff. If you are not really deep into Debian you should prefer reinsalling! Backups are mandatory.

Samba: No mount as user.

Posted by coldtobi | 5 Apr, 2010, 22:48

For security reasons (CVE-2009-2948) samba ceases to support setuid mount.cifs. Until at least a proper fix has been generated (saw patches for them, but at least in Debian they are not or defunc (Patches: http://archives.free.net.ph/message/20100326.142523.e959e38d.en.html, details of the problem http://www.samba.org/samba/security/CVE-2009-2948.html )

(IMHO the CVE is valid, but only makes sense in an multi-user enviorment and if you want to store your passwords in some files. Both are false for me. ) 

However, I need a working system. The other option is waiting until upstreams deciding what's better for me -- a security problem not touching my samba usage or no service at all. (Yes, I'm a little upset by this -- hitten cold by this "improvement" and finding out that they indeed choosen a way to "fix" it by disabling the execution at all. When I read the CVE notice from samba, it could also be done to disable the offending "information leaking" command options when run setuid... Well.)

Well *taking deep breath* lets stop ranting:

Small bugfix for Recaptcha

Posted by coldtobi | 8 Apr, 2008, 10:45

I found a small bug for ReCaptcha: If you do not select a style, the generated Java Script code will be invalid and therefore the lanugage selection will not work.

Just select a style, for example "red" and everthing works fine.

There also some issues with several templates (for example MinimaPlus) : These issues are CSS related and show themself by a "broken bottom border" of the widget. I am currently trying to figure out how this can be solved without the need of a new CSS file to be included.

If you need a intermediate solution, please mail me for instructions.

Digital Camera Fuji Finepix S9600

Posted by coldtobi | 15 Aug, 2007, 12:55

For my upcoming trip, I am planning to buy me a new digital camera. First I was after a digital SLR, but now I found the Fujifikm Finepix S9600.

Its quite an older modell, but the technical details are quite ok. 

As I am currently too lazy to quote all the nice details, I just post an amazon.de link to the project, where all the details are available:
