Apps :: Gnu-utils to replace busybox
1) With most distros, a regular user cannot install packages "system-wide", and so you would either have to install as root, or have each user who needs it install into their home directory. DSL, however, is intended as a single user system. User dsl, in a way, has full root access. Sometimes you, or menu items, have to precede a command with "sudo", though.
When user dsl installs an extension, such as gnu-utils, it replaces the system binaries, for all (both) users, including root.
Also, you might run into strange problems if you log in as another user. Some DSL scripts, and myDSL extensions assume that you are either dsl or root, and might have strange problems. Your mileage may vary.
4) I use Shields Up at grc.com to test a firewall. It is fast, and distinguishes between open, closed, and "stealth." There are many such services on the internet. Most of them are pretty slow, though. One problem with Shields Up is that it won't scan more than 64 ports above 1056, but it will easily scan the first 1056, and that is plenty just to make sure the firewall is working.
