Linux uses DES encryption so you will need the secure version of FreeBSD
then convert the Linux PassWord file to the FreeBSD PassWord file format.
There are probably better ways of doing this, but this well get the two in
sync, and you can go from there.
--begin--
#!/usr/bin/awk -f
BEGIN { FS = ":" ; OFS = ":" }
{ print $1, $2, $3, $4, "", 0, 0, $5, $6, $7 }
--end--
Use it like this (on the BSD machine):
- put the above in a file, eg. /tmp/pw_convert.
- make a backup of your /etc/master.passwd file.
- make another copy of /etc/master.passwd in /tmp
- get the password file off the Linux machine, and put it
in /tmp/linux.passwd. Edit out all the users that aren't your
customers. (eg. 'root' 'bin' and all them)
- use the script :
# cd /tmp
# awk -f pw_convert < linux.passwd >> master.passwd
be VERY SURE that you use the _two_ '>' signs for the output.
- edit the /tmp/master.passwd file, and make sure that it looks
right. Check it :
# pwd_mkdb -c master.passwd
- install it as the new password database with
# pwd_mkdb -p master.passwd
