How to transfer SGI UNIX user on LINUX server
I am transfering all the data from SGI to Linux server. I also need to transfer all the 800 users from SGI to linux with same passwords. Is there any simple way to transfer them on linux (Fedora)?.
Thanks

Re: How to transfer SGI UNIX user on LINUX server
Fedora uses md5 encryption for passwords.
Even if SGI uses the same method it may not work.
Between Fedora machines and Red Hat for that matter, I transfer users by copying the relavvent sections of /etc/passwd and /etc/shadow
then cat passwd >> /etc/passwd etc
If that doesn't work, you may be better off with reading a copy of the passwd file from SGI and use awk to get the user name.
Then with a script you can passwd -f the new account and set a temporary password that the users have to change at first login.
useradd to add the user.

Re: How to transfer SGI UNIX user on LINUX server
you can change the authentication used
on it to that of the SGI machine.
Use the authconfig program, and remove
the MD5 password and shadow password
option.
You must immediately after this set
the password for the root account, else you
won't be able to log in any more! The passwords
for other Linux users should be set as well.
Then you can simply append the 800 users from
the /etc/passwd file from the SGI machine to
the /etc/passwd file on the Linux box.
However, this gives quite a low security,
so you should at leastreenable shadow passwords
after this. I'm not sure if the authconfig
program automatically moves the passwords
from the passwd file into the shadow file,
else you can use the pwconv program for
this.
Note, you can't automatically convert
between md5 and not-md5 passwords.
man authconfig
man pwconv
gives more information.

Re: How to transfer SGI UNIX user on LINUX server
Next time users change passwords on Linux server, passwords will be encrypted using MD5 algorithm.
