random generated password
Hello, When adding a new user it is possible to assign a random generated password. But is it possible to assign a random password for already existing users? Preferably in a non-interactive and scriptable way. Is it possible with the base system tools?

Presumably you're doing this to prevent direct login? chpass allows root to set the encrypted password directly chpass -p '$1$123456789$your-random-chars-here' On Tue, Aug 30, 2011 at 11:16 AM, Michael mlmichae...@gmail.com wrote: Hello, When adding a new user it is possible to assign a random generated password.

Generating a random password can be done with the openssl in the base system; openssl rand -base64 9 You'd want to pipe the output of this command through tee(1) and save it in a file. Next you pipe it to a file discriptor leading to a 'pw usermod -h 0'. Something like this: openssl rand -base64 9 | tee -a newpasswords | pw usermod UID -h 0 where UID is the user-id or name of the user in question.

That occurred to me, but it's a smaller alphabet. Probably doesn't matter if the purpose is to make login unusable. On Tue, Aug 30, 2011 at 11:40 AM, Randal L.
