Default Cannot su

I have had a problem since I started using zsh and I havent worked out how to fix it.

Looks like su doesnt like zsh. In the same machine, I can su to root or any user fine. Never have luck with zsh, it always complain:

Code:
[0:2]gu@server~su                                                                                                     
Password:
zsh: suspended (signal)  su
Im 100% sure the password is correct. I can do sudo fine

Any idea how to fix it? It really annoys me. Thanks

You need to be in wheel group to be able to su
if your not you need to log in as admin or use sudo to add your self to wheel

you can do it by editing /etc/group

This statement is not entirely clear.

Note that su(1) requires a different password than sudo(8). su(1) requires the password of the root account. sudo(8) (if configured as such...) allows root access using the password of a user account.

Likewise, note that FreeBSD will only allow su(1) to succeed (even if the root password is known...) if & only if the user's account is a member of the wheel group.

I didnt know the different password requirement when suing and sudoing.

But I know I must be a member of wheel group to su successfully. And yes, zsh is listed in the /etc/shells file.

Please note the error message, it said "suspended (signal)". As I understand, I did su successfully, but somehow zsh suspended it and put it to background. In other machine, it behaved the same, but I can bring it back with fg command:

Code:
[0:1]gu@workstation~%su                                                                                                
Password:
zsh: suspended (signal)  su
[17:2]gu@workstation~fg                                                                                         
[1]  + continued  su
workstation#
Also, I can su in bash fine. It just happen in zsh

Post your zshrc and zprofile configuration files. There might be something in those.

Exellent. This was because of the line which colorises the stderr.
