Hi, when I use useradd of adduser in CentOS 3 or 4, the default shell a user gets /bin/bash. I want this to be changed to /bin/false for security reasons... How can I accomplish this?
Thanks in advance for any help.

useradd --help --> -s Shell
So just use that parameter like "-s /bin/false".

I think what he means to do is not add that parameter each time he uses `useradd'
I believe the file you want to look for is /etc/default/useradd or somesuch.
Thanks!

Alexander,
Haven't seen you around in a long time. What's the haps man?
Here's a side question in relation to the shell. Which convention is more correct, or does it even matter. /bin/false or /bin/nologin?

A bit busy in the last weeks - and did post enough in the last year on the Fedora list ;)

With the /sbin/nologin shell you get a feedback that the account login is disabled. /bin/false is just silent. What you use depends on specific target. For login-less FTP user account for example I prefer /bin/false.

/etc/default/useradd

adduser -s /bin/false loginname
if the user is already created... you can use chsh to change their shell. ie: chsh -s /bin/false loginname
Refer to useradd(8) manual page.
