Try...
su - root
It should then ask for a password, enter the root password, and the prompt=
should change to indicate you'r now root.
Like this....
(After successful login as a plain user, who has the rights to enable them=
to su
of course!)
Welcome to Dave's FreeBSD!
$ su - root ('user mode')
Password: (enter root password here, but it is not echoed to the terminal)
# /root > (now in 'root' login mode.)
NOTE! The 'space,hyphen,space' between the 'su' command, and the 'root'
argument. Comments between () are not shown on screen of course.
When done doing root stuff...
Use Ctrl+D (^D) to exit the root mode back into your user mode, and again =
^D
to exit the machine.
I do the above from various windows boxes to my FBSD box at home, from
within the LAN, or from outside. As I just did, to get that example above=
.
I use PuTTY on Windows for this sort of thing, as that also gives you some=
tunneling abilities if you need to reach into somewhere else on your LAN f=
rom
outside, such as to run VNC to admin' another machine somewhere for exampl=
e.
Best Regards.
