Redhat 9 SU Command/Password Problem

[DevilishPope]

I'm not entirely sure where this goes, so bear with me. I am new to Linux, and I recently installed Red Hat 9, and upon finding out I needed to update the SSLCertificate to obtain Kernel upgrades, I downloaded it, and followed the instructions. My problem is that when I type in su, it asks me for the root password, and will not allow me to type one in. I can smash all the keys and nothing works except enter, which does me no good, since I cannot enter the password for Validation. I'm wondering, how can I fix this problem? I have the same problem on another machine I installed, and it's rather annoying. Thanks.

its not actually a problem. You only notice enter working because its all that seems to do anything right?
Don't fret, the password is masked, just try typing it in and pressing enter. That should clear things up for you...

yeah like android said you will not notice that you are actually typing it looks like you are doing nothing but it is recording what you type so jst type in the psswrd and then hit enter and see what it does
