how to find users without a password

[Quark]

Hi,

is there a way to find all users on a trusted system that have no password (they can logon without a password) without having to logon one by one to check (manually)?

With kind regards,

Kris

Kris,

logins -x

will report you this information.

Such users will have "NP" as password status ("PS" for valid password)
ex with valid password:
user1 10000 ftponly 10000
/home/user1/./
/usr/bin/false
PS 040506 0 182 7

Hi Kris,

You can use "logins". Check the man page for more information.

Hi Kris,
logins -p if you are root
otherwise on HPUX11i the users with the password disabled (they are using ssh) have !! in the /etc/passwd after the name, i.e.:
user:!!:
