understanding /etc/passwd.

[senthil_kumar_1]

For example /etc/passwd file is

1)root:3Km/o4Cyq84Xc:0:10:System Administrator:/:/sbin/sh

2)joe:r4hRJr4GJ4CqE:100:50:Joe User,Post 4A,12345:/home/joe:/usr/bin/ksh

Here the second field contains encrypted password in both the entries.

That is some passwords (real words with letters) are converted as Encrypted password and entered here in second filed.

So I am asking that how to creata a real password as encrypted password?

Hi,

root:3Km/o4Cyq84Xc <<--

The password is in encrypted.

The idea behind changing the system to trusted or creating a shadow password is to change the location of /etc/passwd.

"So I am asking that how to creata a real password as encrypted password?"

Good question..

But it is not possible, since when you provide the password, lot of algorithm gets executed and hence the above encrypted password gets generated.

[Avinash20]

How about assigning some points :)

[senthil_kumar_1]

Is it possible that some lines have "*" and others have "encrypted password"?

Ex: /etc/passwd

1)
cmurphy:*:200:21:C.C.Murphy,US HQ,6588,:/home/murphy:/bin/ksh
2)klabunde:*:252:28:M.C.Klabunde,,,:/home/klabunde:/bin/ksh
3)pwrchute:zf67.sLB9vFPE:257:10:PowerChutePlus,,,:/home/pwrchute:/bin/ksh
4)
weber:*:277:32:D.M.Weber,eds,,:/home/weber:/bin/ksh
5)
mckeen:xQUDOfLwcnNB6:338:36:C.A.McKeen,EMD LMC,,:/home/ccm/home/mckeen:/bin/ksh
6)
ktieman:4Py4ttQiGGxo.:365:36:Ken Tieman,EMD LMC,,:/home/ktieman:/bin/ksh
7)
dandawat:xVUyMpkuSeWUY:399:21:Y Dandawate,,,:/home/pz2tl1:/bin/ksh

Hi Senthil:

> So I am asking that how to creata a real password as encrypted password?

# cat mypwgen
#!/usr/bin/perl -l
die "One arg expected\n" unless @ARGV;
print crypt(
$ARGV[0],
join( '',
( '.', '/', 0 .. 9, 'A' .. 'Z', 'a' .. 'z' )[ rand 64, rand 64 ] )
);
1;

...run as:

# ./mypwgen plaintextpw

...the output will be an encrypted password suitable for use with 'useradd'.

Yes,

Convert the system into Trusted

# /usr/lbin/tsconvert

Password will be in *

Then untrust it

# /usr/lbin/tsconvert -r

Then change the password of any user.

Only for the above user the password will be in encrypted format.

what is the default system "shadowed" or "trusted"?

[James R. Ferguson]

Hi:

Be advised that the Trusted system implematation is deprecated at 11.31 and will not be supported thereafter. You should consider converting to an '/etc/shadow' implementation.

If you are running on 11.11, you can install:

http://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=ShadowPassword

If you are running 11.23 or 11.31, no additional software needs to be installed.

Chapter-8 of this guide discusses this:

Neither. By default the system will come with normal /etc/password having encrypted password.
