Linux Upgrading Issue

winmelnx · 01-26-2003, 01:42 PM

Is there anyone can give me a clear and straight
solution to login as a root user after I upgraded my Red Hat v6.1 to v7.2 ?
After I completed the upgrading progress, I can login by using my regular user name with the previous password. However, for some unknow reason I can not use the previous root password to login system as a root user. It's look like to me, The upgrade
processing changed the root user's password. I would very appreciated for any suggestion.

Welcome to LQ.org, winmelnx!

I've never seen the upgrade process overwrite the root password. Have you tried 'su' to see if you can log in as superuser with the root password?

Otherwise, you could use an emergency disk such as Toms Root Boot disk to boot up a separate linux, and check the /etc/shadow file to see if there's an entry there for root.

Thanks Bert, I tried every your suggestion. But It's still not
work. Any other good ideas? I would really appreciate it.
By the way, What's you mean of Tom root boot disk?
How you can boot to another copy of Linux without to be asked
password?

Basicly it will let you boot up and then you can mount your partition (am I correct?). Also, you could boot into Linux Single I believe and there wont be any password and all you do is change the pass.

Thanks Vexer, but I still don't get it. Can you show me a step by
step procedure or where I can get the necessary Toms root boot
disk?
