Once again, a completely useless Subject.

_Why_ would you wish to do this?

Ask someone else to set the root password for
you, and then not tell you what it is?

Disabling root login can have some undesirable effects. I have run into problems in Ubuntu, since it by default has a disabled root account.

If you still wish to disable root login, you need to edit /etc/shadow.

The entry for root would be like (for e.g.):
root:$1xxxx:1234:344:0:::

You need to replace the string between the first colon & the second colon. In above example change $1xxxx with * so it looks like:
root:*:1234:344:0:::

Be careful not to edit / erase any other strings. Root user is most integral part of a Linux / Unix system & should not be messed with in my opinion. :)

i would like to know which problems you had on ubuntu with the disabled root account.

better question to ask is how to deny remote root logins. i don't think root should be disabled in total though.
