I am trying to configure Tacacs+ in Fedora 8.The question is how do I generate the DES key for the user's password:

user = test {

default service = permit

login = des xxxxxxxx

expires = "Sep 1 2009 "

Any ideeas?

There should be an option in tacas+ to do that.

If not, you could use a program to build one yourself

use Crypt:ES;

my $key = pack("H16", "0123456789ABCDEF");
my $cipher = new Crypt:ES $key;
my $ciphertext = $cipher->encrypt("plaintex"); # NB - 8 bytes
print unpack("H16", $ciphertext), "\n";
Have a look here.

Thanks a lot.Acctually I manage to generate the des key with the generate_passwd utility after a long search .... 'generate_passwd is a program to des encrypt a password like Unix. It prompts for the password to encrypt. You can optionally supply a salt to verify a password.'

Solution: use tac_pwd

Provided by: tacacs+_4.0.4.19-9_i386

tac_pwd - generate DES encryption of a password

tac_pwd [-eh] [salt]

tac_pwd prompts for a clear-text password and produces a DES encryption
of that password on stdout which may be used in lieu of the clear-text
representation in the tac_plus.conf(5).

The DES salt may be provide as a command-line argument.

-e Do not echo the plain-text password to the terminal.

-h Display help message.
