passprase error and data loss

[yashodeep28]

I have rhel5 installation on my laptop and at the startup there is prompt for lucs passphrase. Since some days I am not getting this passphrase prompt and all my important user data is lost. The system starts without passphrase.

You have not asked any question and so we can't understand your real problem.

Do you know your passphrase ?
Have you forgotten your passphrase ?
Do you think your data is lost because you are no longer prompted for your passphrase ? That won't be true and don't delete, format or repartition anything !!!
Do you remember if you encrypted a whole partition or a file/folder ?

thanks for the concern,
i remember the passphrase but my data is lost and i am no longer prompted for passphrase. i am not able to retrive the data. please give me solution if possible

You must know at least where your data is : on a whole partition or as a file mounted on a loop device. I can't know how your system tries to mount the encrypted data at boot, perhaps through a service run at boot time. Please give more information :

As root :

uname -a > /var/tmp/cr.txt
chkconfig --list >> /var/tmp/cr.txt
fdisk -l >> /var/tmp/cr.txt
df -h >> /var/tmp/cr.txt
which cryptmount >> /var/tmp/cr.txt

Best would be to tell us if you know where is your encrypted data.

Post the file /var/tmp/cr.txt as an attachement.

my data was on the user profile. i am posting the file /var/tmp..........

The data you sent seems crap and is not what these commands output. And user profile is not really meaningful.

What's important is to locate your encrypted data.

You can then manually mount them as follows :

cryptsetup luksOpen /dev/XXX# atag
mount -t auto /dev/mapper/atag /amountpoint

where /dev/XXX# is the partition containing your data.
