moduser on Ubuntu 8.04

I'm finally getting started with the software. I installed Ubuntu 8.04 on my machine, followed the instructions for installing all the extra Java stuff (j3d, etc). One instruction didn't work on my machine.

rsteff@moonguide:/usr/lib/jvm/java-6-sun/jre$ sudo moduser -G `groups |sed 's/ /,/g'`,dialout `whoami`
sudo: moduser: command not found

Was moduser replaced between Ubuntu 7 and 8, or did I miss something?

I don't have any hardware to connect, yet, so I was hoping the serial port didn't matter. I do have something connected to a serial port, but I don't have it running yet, either.

Recommendations on how to proceed are welcomed.

Thanks.

If the output of

groups rsteff

shows dialout additional to some other groups, you are already in and there is no need to add your user to dialout.

If not you can

1.
Use the mouse, go to the system preferences menu > users/groups and check modem connect for your user.
(or something like that. My menus are not in english, so I don't know the correct expressions.)

2.
Use

usermod

instead of

moduser

This should work.

If I am wrong with the second way someone else should stop you

Thanks. I had my machine at a Linux group clinic this afternoon where there are several Ubuntu users. They had me use

sudo gpasswd -a rsteff dialout

That worked fine. It let me start the program. It didn't get past the terminal window stage, but I'll have to run it again tomorrow to see the error messages and figure out what question to ask next.
