I'm not able to connect with SSH because of SUID warning

Question

When I try to connect with another machine, after this command below:

user1@host1:~$ ssh user2@host2
user2@host2's password: 

I receive:

WARNING: Your password has expired.
You must change your password now and login again!
passwd: must be suid to work properly
Connection to host2 closed.
user1@host1:~$ 

• host1 is Ubuntu OS machine

• host2 is Buildroot OS machine

Obviously I've changed my password, but it didn't help.

What is wrong? How can I fix it?

Solution

SOLUTION:

The source of the problem is the date on my ARM board. This is the reason that the 'password has expired'.

To set up correct date, use:

# date -s '[current date]'

command on an ARM board, and:

# hwclock -w

to keep date settings on the hardware.

You were about to change the password on host2? (Your post said "hanged" and I think you meant "changed" but maybe you mean "mucked up"? If you want to reset and create a new sshkey you can delete the lines corresponding to host2 in .ssh/known_hosts

@beroe: I just want to get access to host2 (with Buildroot) via ssh, but it's just sending this warning and my connection gets closed. I don't know what is wrong.

Do you have physical access to the machine? Are you able to login directly to the console?
