I'm still a bit green when it comes to Linux, but I'm trying to get IPTABLES
going.

I've been going through a pretty good book on the subject, but a lot of the
rules and policies I've put in give errors.  So I copied the exact script
from the books web page, and it does the same thing!  He's the page for
reference.
http://www.linux-firewall-tools.com/ftp/firewall/standalone.firewall.1

I'm running Redhat 7.2 with IPTABLES enabled and running (IPCHAINS is
disabled).  I get errors such as:

: command not foundll
iptables; Bad policy name

and

: command not foundll
'ptables v1.2.3: Invalid target name 'DROP

and

: command not foundll
'ptables v1.2.3: Invalid target name 'ACCEPT

and

'ptables v1.2.3: Unknown arg '--flush

I get a lot of the errors listed above.

I also get errors on some of the kernel commands like

# Enable TCP SYN Cookie Protection
echo 1 > /proc/sys/net/ipv4/tcp_syncookies

it says the file is not found?.......

Now, I'll give some info on what I did incase it has something to do with
it.   Because my test Linux box is in an odd spot in my room.  I typed the
script out in Notepad on my WinXP system, named the file rc.firewall, and
saved it.  Then I put it in the /etc/rc.d/ directory and did the following:

chmod u=rwx /etc/rc.d/rc.firewall
chown root.root  /etc/rc.d/rc.firewall
chmod u=rwx /etc/rc.d/rc.firewall

and put the line sh /etc/rc.d/rc.firewall in the rc.local file.   I don't
know what the hell is going on.  Does RH 7.2 use a different version of
IPTABLES where these commands don't work?  Did making the file in notepad
funk it up?

Any help on this would be great!
