RHCE EXAM PART 1 (root password and single user mode)


At the very beginning examiner will give you a work station with rhel-5.3 installed.
He will not tell you the password of root account.
To access your work station you have to login in single user mode and change the password of your own.
Which, you will have to change afterward.

After seat for the exam reboot your machine and when the first boot screen appears press 'b' before countdown goes to 0 seconds.

Then the another screen will appear and select the line stated “Redhat Enterprize Linux Server –(xxxx)”
 Select that line and press 'e'.

Now type:
Sh-3.1# passwd
And give your password twice
And type 'reboot'

Then press enter

Now machine will boot normally and you can login with the password that you have just given.
After login you will see a page where you have to put your name
(please check the name as exactly waht you want to see on your RHCE certificate) and email id.
Then a password will be generated automatically in a text file at your desktop.
Where, you will find the root password for the exam. Just change the root password as told in the file. Example:
Suppose you have set a password redhat by using single user mode.
But the file says your password will be hatred.

#passwd
And type 'hatred' twice.


Note: In redhat  linux e means edit, b means boot. Your should give your valid email id on the user form. Please try to use gmail cause sometimes yahoo and hotmail bounce the mail from redhat or put it to junk folder. Cause you pass or fail redhat will send you a mail. And also check the spelling of your name. I think you wont like to get a online certificate with misspelled name.

And last, please click some of the adds on my blog. This will generate some money for me via adsense.

That is the first part of the RHCE. Next I will post about network setup of RHCE exam.

Thanks.
