In debian lenny with encrypted root and swap partitions, when booting, one is asked for root and swap passphrases. To avoid the swap passphrase, a working setup is found here: http://agnulinuxuser.blogspot.com/2011/12/encrypting-swap-partition.html

also ensure that the sudo echo command is all on one line. It doesnt appear so well in the web page here, but its supposed to be on one line.

Hi Rod,
Normally that would indicate that the user you ran the command as does not have enough permission to access the /etc/crypttab file. try becoming root and doing the echo that way

[code]
sudo su -
echo cryptoswap /dev/sda3 /dev/urandom cipher=aes-cbc-essiv:sha256,size=256,hash=sha256,swap >> /etc/crypttab
[/code]

if that also fails, then copy/paste the resulting failure as well as the output of

[code]
sudo ls -la /etc/crypttab
[/code]

Hi,

Everything worked well until I got to this line:
sudo echo cryptoswap /dev/sda3 /dev/urandom cipher=aes-cbc-essiv:sha256,size=256,hash=sha256,swap >> /etc/crypttab

I received this error message:
/etc/crypttab: Permission denied

(Note: I changed from your sda3 to my sda5)

Any thoughts?

Cheers,

Rod
