Let's look at this again - the Op asked if he can change the root
password he he does not know it.

That being said - ha can't run sudo without knowing the root password.
Unless of couse, the admin of the remote box setup sudo to be used
without a password.

ARE WE CLEAR ON THAT?

How can a user use sudo if he does not know the password (assuming the
root password is needed to use sudo). 

The Op does not define other parms in the request - here's the quote:

"On Monday 13 August 2007 22:06:32 Cesar Augusto Suarez wrote:
so, however, if i  have remote access  by ssh to a linux
machine, can i change the root pass if i dont know it? just in case"

The Op does not define what distro, he does not define whom he is
ssh'ing in as - it is what it is.
