The `cdcontrol' command works fine with my ATAPI CD-ROMs.  I haven't
used it with SCSI CD-ROM devices, but AFAIK it works for those too.

None, at all.

This does not imply that there are no problems regarding the security of
a BSD system, ever, at all...  At times, there are bugs and security
problems with programs that can be run on a BSD system too.  None of
that crap with virii taking over unsuspecting users' home machines and
launching attacks on random IP blocks on the Internet causing all sorts
of havoc and disturbance to the world though.

Netstat is fine, but I usually prefer sockstat when I'm sitting in front
of a BSD shell.  The output is more informative when one cares to know
exactly this sort of thing (which process has opened which connection):

: [EMAIL PROTECTED]:~$ sockstat -4
: ncvs   cvsup     4664  4  tcp4
: root   sendmail  3721  4  tcp4          *:*

: root   named     1738  20 udp4          *:*
: root   named     1738  21 tcp4          *:*

Kill the PID that has opened the connection and off it goes.

Aliases are a shell-dependant feature.  The default shells that are part
of teh FreeBSD base system have the following ways to define aliases:

  1. Interactively:

     As you type commands in your /bin/sh prompt, try this:

          $ alias ls='/bin/ls -FGh'

     In tcsh, the '=' sign is not necessary but pay very careful
     attention to the quoting of special characters, because tcsh(1) is

          % alias ls /bin/ls -FGh

  2. In startup files

     Whatever you type in the command line can be stored in a shell
     startup script, making it effectively persistent across login
     sessions.  Each shell has its own startup files; sh(1) uses
     `.profile' and `.shrc', while tcsh(1) reads `.tcshrc', `.login',
     and `.logout'.

Journaling metadata isn't supported AFAIK by any version of FreeBSD.
If the filesystem hasn't been mkfs'ed to use some of the special,
unportable to other systems, Linux-specific features of ext3, you
might get away with mounting it as ext2.

Read about xset(1) in XFree86.  Especially the sections about `dpms'.
This should work while you're using a GUI.

I use "metaports", i.e. ports that I have written which depend on all
the ports I regularly use.  This is a sort of hackish way to update your
ports, but I usually update my installed ports only when there is a
security problem with one of them.  Which is a lot less often than the
updates I do to the base system with CVSup, buildworld, etc.

A lot of people like `portupgrade' for keeping their ports up to date.
It's available in the ports and there are dozens of tutorials online
that explain how it works.  A quick google search yields:
