crypt PLAINTEXT, SALT
Where PLAINTEXT is the password in this case
Where SALT is a two character string, matches regexp /[./0-9A-Za-z]{2}/
Many people use seconds to come up with a SALT string but in a tight loop you may pull the the same second. Do something with this...
That will give you a factional time where you can use string operators to suck out two digits at a time and the modulo them to the set of 64 characters available for the SALT with...
So we call these two functions in Perl and return the password.
See attachment for Perl code and remember to 'chmod' it. We can now get the proper password in BASH with...
I tested the 'useradd' command and it worked correctly with adding the account under Fedora12. Sorry for the hedge bet but the documentation says the default '-p' option is to disable the account? This sounds strange.
I work on some hp ux 11.00 Servers. i have to add an user. i use the useradd command like follows: useradd -u 72022 -g 71095 -c " comment " -d /PACKAGE_NAME/home/username -s /usr/bin/sh username
The command returns with error 3. The manpage means value number 3: Invalid argument supplied to an... (6 Replies)
Hi.
due to some needs i gave a user the premission to use useradd command with sudo.
i want to know if there is a way to let him set the initial password, without giving him the premission to use passwd command as root (sudo).
maybe a way to set a default password for all the new users that... (2 Replies)
Hi,
I need to add a new user who will only be able to access one single folder on my Solaris 9 system. Can this be achieved by using just useradd or do i need to fiddle with auth_attr table?
TIA,

The man pages for useradd show the -k flag as a option, problem is I don't know what the description means. Could someone explain what "an alternative skel directory" is?
Is skel an acronym?
Thanks
From the man page:
-k, --skel skeldir
Specify an alternative skel... (1 Reply)

md5crypt
md5crypt(n) MD5-based password encryption md5crypt(n)
__________________________________________________________________________________________________________________________________________________NAME
md5crypt - MD5-based password encryption
SYNOPSIS
package require Tcl 8.2
package require md5 2.0
package require md5crypt ?1.1.0?
::md5crypt::md5crypt password salt
::md5crypt::aprcrypt password salt
::md5crypt::salt ?length?
_________________________________________________________________DESCRIPTION
This package provides an implementation of the MD5-crypt password encryption algorithm as pioneered by FreeBSD and currently in use as a
replacement for the unix crypt(3) function in many modern systems. An implementation of the closely related Apache MD5-crypt is also avail-
able. The output of these commands are compatible with the BSD and OpenSSL implementation of md5crypt and the Apache 2 htpasswd program.
COMMANDS
::md5crypt::md5crypt password salt
Generate a BSD compatible md5-encoded password hash from the plaintext password and a random salt (see SALT).
::md5crypt::aprcrypt password salt
Generate an Apache compatible md5-encoded password hash from the plaintext password and a random salt (see SALT).
::md5crypt::salt ?length?
Generate a random salt string suitable for use with the md5crypt and aprcrypt commands.
SALT
The salt passed to either of the encryption schemes implemented here is checked to see if it begins with the encryption scheme magic string
(either "$1$" for MD5-crypt or "$apr1$" for Apache crypt). If so, this is removed. The remaining characters up to the next $ and up to a
maximum of 8 characters are then used as the salt. The salt text should probably be restricted the set of ASCII alphanumeric characters
plus "./" (dot and forward-slash) - this is to preserve maximum compatability with the unix password file format.
If a password is being generated rather than checked from a password file then the salt command may be used to generate a random salt.
EXAMPLES
% md5crypt::md5crypt password 01234567
$1$01234567$b5lh2mHyD2PdJjFfALlEz1
% md5crypt::aprcrypt password 01234567
$apr1$01234567$IXBaQywhAhc0d75ZbaSDp/
% md5crypt::md5crypt password [md5crypt::salt]
