The quickest way to find out would be to copy one entry from Linux to FreeBSD and see what happens. Under FreeBSD there are two hashing engines used, MD5 and DES. DES is not provided by default. I think a hashed (the mess you see in the 2nd field of the passwd entry) MD5 password begins with a dollar sign. A FreeBSD system with DES will take either but new passwords will be DES. DES is required for NIS to be compatible with other Unix (and Linux) systems. So I'd guess somehow Linux has DES. > Another questions is about new format password on Free > BSD.

If you upgrade by sources this might take care of the passwd format for you. I know this machine started out as 2.2.x and went thru 2.2.[5678] before making the leap to the 3.x series. Believe when I made the leap I used the upgrade option from CDROM but have used the source technique on other systems. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
