Hi

You are correct to a point. Any user in on a windows platform that has is in group administrators is dangerous.

QUICK TIP:
To run programs as root, when required you can use "sudo".

EXPANDED:
When running as root, edit "/etc/sudoers" and grant yourself privledge to certain commands or all commands. Then when running as a regular user you can execute the enabled commands like this :
sudo /sbin/ifconfig

If the commands have pipes or redirection then theres a trick required.
EXTRA TRICK:
sudo bash -c "cat /etc/hosts >/dev/null"
This is how you can run commands requiring pipes "|" or redirection ">".

Limiting users access to "special" commands can help with security and flexibility conflicts, this is done the best using sudo.

Hello everyone,

I found this thread interesting reading. I am one of those "ordinary
Win*DOH*s" users referred to earlier in the thread. I started using
windows with vs 1.0 or so. I think I skipped 2.x and then used 3.0 and
every version since then as well as every version of nt since 4.0.
I manage a small network that is served by Windows 2000 Pro (not server)
and will have to upgrade it to handle more users in the next 6 months or
so. In the meantime I am trying to learn enough to setup a Linux server
instead of continuing with m$.
One of the contributors mentioned earlier about not running things as
"root". The only book I have for Linux is Red Hat Linux 7.2 Bible.
Well, I haven't learned very much about Linux yet, but the book taught
me to create a user account and do all work from the user account and
not to use the root user at all. It says, rather, to use the superuser
command as needed. As a result of what I learned from the book, I have
gone back to all my XP/2000 computers and changed all users back to
"user" and setup special admin accounts for those occasions when it is
required to use admin privileges. I discussed this issue on the NT
listserv and learned that while it isn't a perfect solution, using
"user" privileges offers a lot of protection even in NT based windows.
There is definitely a learning curve to cross over from windoze to
Linux.

As I have 8.0 questions, I will be posting them here.
Buck

1. Let's create a file name asdf in your home folder;

and enter this code:
     Sub AViciousCode
        Shell( "rm -rf ./asdf",2)
     end sub
3. Now run it to see your asdf file has gone!

There are other problems, such as the fact that OO.o will only run
macros from a file opened within certian directories. /home/$username is one of
them, but not any subdirectories. So, unless you download the email message
to your home directory, and _then_ open it, you won't have a problem.
