incorrect password when logging in as su -
 

When logging into server via telnet I can login in with admin user and password fine, but trying to su - to root, I type the password and recieve incorrect password.

I have reset the password numerous times, checked the passwd, shadow and group files all is correct.

Do you have any troubleshooting procedures or fixes for this issue? Any help would be much appreciated. Thanks.

You may have system security set so high as to not permit su root logins remotely. Check into that.

hmmm... if you use some strange characters in your password then maybe they are not supported by ssh. Also possibly if the keyboard region is different at work??? but if you are using regular characters for your password then forget all the above ;)

Good luck!

What distro did you say your using?
Try adding you user name to wheel group.
man usermod

Also consider using sudo to preform SA task like, roboots,
mounts, useadds, ppp etc.

man sudo
man visudo
man sudoers


The idea being you want to spend a little time as possible
logged in as root.:study:
