Operating Systems Solaris How to scp shadow file of b form system a? Post 302761755 by jim mcnamara on Saturday 26th of January 2013 07:40:11 PM

on Server A
as root user
Code:
chmod 444 /etc/shadow

on server B
as root user
Code:
chmod 644 /etc/shadow
cp /etc/shadow /etc/shadow.keep   # this is to revert if it screws up
scp me@serverA::/etc/shadow .
chmod 400 /etc/shadow

TEST several user logins on serverB. Note: Create separate processes for login testing, KEEP YOUR root PROCESS active no matter what, so if you broke stuff, you can still fix it. If you really broke things, nobody can login to serverB, including root. Use the copy /etc/shadow.keep to restore.

Go back to serverA
Code:
chmod 400 /etc/shadow

This effort will not work to duplicate passwords if you are using NIS or LDAP or you have messed with PAM setup on either box.

pwconv(1M)						  System Administration Commands						pwconv(1M)

NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd SYNOPSIS
pwconv DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd. pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is already in /etc/shadow and should not be modified. If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates /etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in /etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated. If the /etc/shadow file does exist, the following tasks will be performed: Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file. Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow. Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre- sponding entry in /etc/shadow. The pwconv command can only be used by the super-user. FILES
