Hi Dan, Since I'm not aware of any automated tool for doing what you want, here's what I would do: - Look at FreeBSD's master.passwd file, each entry consists of the following fields, seperated by ':' name User's login name. password User's encrypted password. uid User's id. gid User's login group id. class User's login class. change Password change time. expire Account expiration time. gecos General information about the user. home_dir User's home directory. shell User's login shell. - Find the corresponding fields in RedHat's passwd and shadow files. - Write a (perl?) script to create a master.passwd from the passwd and shadow files - Move the master.passwd file to the FreeBSD box in the /etc directory and run the command: # pwd_mkdb -p /etc/master.passwd That will create the necessary password database files for you. Disclaimer: I don't know what format RH uses for its encrypted passwords, so maybe you'll have to write another script to generate new passwords for each user. hope this helps, Ruben > > -Dan > dan037@yahoo.com > > > > __________________________________________________ > Do You Yahoo!? > Yahoo!
