AFAIK, both CentOS & Ubuntu uses MD5 to encrypt the clear text password. No diff.
You could try by simply copying and pasting the encrypted password from CentOS to Ubuntu for one user and try logging in. That should give you the answer. :) As for changing passwords for 8000 users, bash is you friend. A for loop with 'usermod -p' would do. Hope that helps. - Zia P.S.: Logged in to my Mailing List email after a long time and saw your email, could not help but reply. :) On Sun, Jul 26, 2009 at 12:39 PM, Fakrul Alam<[email protected]> wrote: > Hi, > I have one mail server running on CentOS 5.1 which contain > around 8000 users.
