sourceforge and openid
Posted by ebal at 19:45:12 in blog, planet_Sysadmin

I am using OpenId and i have a personal OpenID provider based on simpleid.

I used to be able to login to sourceforge via https://balaskas.gr but i’ve removed my SSL from my website
(My SSL cert is signed by cacert and firefox doesnt accept cacert - thats another story).

So i wanted to re-configure my sourceforce access with http and openid.

I cant !

“There was an error using your OpenID.”

My logs

216.34.181.60 - - [21/Nov/2012:08:39:33 +0200] “GET / HTTP/1.1” 200 951 “-” “Zend_OpenId”
216.34.181.60 - - [21/Nov/2012:08:39:33 +0200] “POST / HTTP/1.1” 200 951 “-” “Zend_OpenId”

i’ve opened a support ticket but i got this:

“While we certainly allow users to use custom OpenIDs, we cannot guarantee that they work with our site. As such, we’re not going spend time troubleshooting that.”

right …. custom OpenID !

for the love of Bob, i am using a personal OpenID provider - i dont have a custom openid !

The investigation of LVM2
Posted by ebal at 12:29:51 in planet_Sysadmin

This is a rather large post, so you need to have some time to read through it.

I was interested into learning/identifying how data are written on a hard disk using LVM2.
All that begun when i was trying to extract partitions from a corrupted disk with no partition table!

Steps:

  • Create a disk image
  • Create Physical Volume
  • Create Volume Group
  • Create Logical Volume
  • Format Filesystem

using only basic cmds [ du, fdisk, file, hexdump, losetup, strings, truncate ] and LVM2 basic cmds.

to reduce the size of this post, the latest couple hexdumps are located in separate files (12K and 172K) provide them with links.
Plz click on them just to see the output. They are very interesting.

So lets start

A. Create disk image file



# truncate -s 5G&nb...

Thank you.
