Just before someone complains about my usage of awk, it's of course:
ps aux | grep [.] | awk 'BEGIN {} { cpu += $3} END {print "CPU (Total): " cpu "%"}'

Is there a Linux equivalent to Dos's debug which allows viewing of binary
files in hex format?

I have an Apache server running on Redhat 6.2 and it works fine with simple
HTML pages, but when I try to use CGI scripts I get a 403 error. In the
httpd error log it says that its because of restricted access and that I can
clearly understand but how and where do I change it so that I can let people
run the cgi scripts without this error message?
I know that the directory is correct in the httpd.conf for cgi-bin so its
not that.
Thanks in advance.

No. There is nothing there to get that speed. IF you send teh right
setup commands to your modem, then after the CONNECT report (in the chat
-v output) it may list the connection speed-- either computer to modem,
or modem to modem depending on how you set up your modem.

This is the wrong output It is the ouput from pppd. There is no way ppd
even could tell you what the speed is.

You may not use echo here since messages is often being written to
by syslog. If so, then use logger, e.g. like this ...
echo `date` $HOSTNAME "Yi["$PPID"]: Starting Yi.org" \
/sbin/logger -i -p user.notice -t Yiorg
... and mind the `date` syntax.

The directory that your cgi-bin scripts are in needs to have the access
'x' permissions bit set for the user which runs apache. The script itself
will need to be at least readable by the same user, and any parent
directories will also need the 'x' bit set (e.g. chmod 751 /dir).

The version of GNOME which came with Redhat 6.0 was known to be a little
buggy. You should check out Helix Code (http://www.helixcode.com) which
can help you easily install the latest greatest GNOME for your Redhat 6.0
system.

To work in user mode you'll need to add the ppdev kernel modules if you are not using
kernel 2.4
Check on my web site on the first Linux page for the proper module
Here is an example of some code, download my AVR microcontroller programmer to see
more.
I use ioctl to access /dev/parport1 which is a Lava PCI parallel card. You can change
the code to use /dev/parport0 instead
The reason I am using the kernel module is that is the only way to access the port in
user mode. You have to be on root otherwise. It works very well this way.
unsigned char parallel::wr2SPI(unsigned char c)
{
unsigned char x = 0;
