Convert master.passwd into gentoo/linux style passwd

[blacharz]

Hello,
i've got problem, i'm trying to convert my users passwords stored actually on freebsd (master.passwd) into gentoo /etc/passwd /etc/shadow passwords.
What can i do? Because normal copy and paste strategy is not working...
Any ideas? Please help

What's not working?

Don't you just move /etc/passwd to /etc/passwd and /etc/master.passwd to /etc/shadow or something like that?

Hi.

Do both systems use the same encryption methods for passwords?

If not, I doubt that copying will work. Instead of copying the entire file, you could try a test case with just one encrypted password for which you know the unencrypted string and see if you can login.

Interesting question; keep us posted ... cheers, drl

I've tried to copy only password string to the new added user on my linux system and it failed. Copying whole line from /etc/passwd and master.passwd fails - i can see the log:
su(pam_unix)[2531]: check pass; user unknown
su(pam_unix)[2531]: authentication failure; logname= uid=1000 euid=0 tty=pts/0 ruser=marcin rhost=
su[2531]: pam_authenticate: Permission denied
matrix su[2531]: FAILED su for romek by marcin

where romek is user that password i know and marcin is my username.

I think that maybe there is something with this PAM authorization??

Ok - i found the solution - i wrote perl script which did the job for me - the only thing i must do is to set this pass string from master.passwd and then add it to useradd command.
f.e.

useradd -c 'Somebody' -m -p 'encoded_password_from_master_passwd'

And it works - password works ok.
Bye!

Hi.

I'm glad to hear it was resolved. I'm surprised that they used the same encryption, but that turned out to be good for you.

I wonder why the copy / paste of the encrypted string didn't work? Perhaps I'll play with that ... cheers, drl
