Hello The Answer Gang,
I have a question about the following article: http://linuxgazette.net/107/tomar.html
I did the following:
"Delete everything between the first and second colons, so that the line looks like:" root::12581:0:99999:7:::
"Save the file and exit your editor"
"Type 'reboot' to reboot your system"
However I can't complete this step:
"Now you can log into your system as root with no password. Make sure you change the password immediately."
When I try to login through putty, it asks me for login name, I enter root, then it asks me for password, I just hit enter, and it says the password is invalid.
How exactly do I login with no password?
Thanks!

The article talked about login on the console presumably. The "ssh" daemon is usually configured to not allow empty root password logins.

I didn't know that about ssh.
It worked through console. Thanks!

Helpful hint: please refrain from top posting. It's more natural, and generally considered better form, to include your replies at the bottom of the e-mail or inline for better flow.

Another good barrier is that root login is often disabled over ssh, with empty passwords being disabled for all users. This forces users to use sudo (a "good thing").
These and more settings can be found in either the ssh daemon or pam configurations.
