Shorewall Issues

[Hayes43]

Hello: I have used these instructions to install Shorewall Firewall.

They fail each time.

Any advice would be very much appreciated.

Install a Firewall
We now are going to lock down our server a bit more by installing Shorewall, a command-line firewall. To install it
sudo aptitude install shorewall
By default, Shorewall is installed with no rules, allowing complete access. However, this is not the behavior we want.
Instead, we’re going to block all connections to anything other than port 80 (HTTP) and port 22 (SSH). First, copy the configuration
files to the Shorewall directory:
sudo cp /usr/share/doc/shorewall-common/examples/one-interface/* /etc/shorewall/
Now, open the “rules” file:
sudo nano /etc/shorewall/rules
Thanks again

So, how exactly does it fail?

When I use this command sudo aptitude install shorewall
I receive this. O Packages upgraded, O newly installed, O not upgraded.

When I use this command sudo cp /usr/share/doc/shorewall-common/examples/one-interface/* /etc/shorewall/.
I get this message. CP-cannot stat no such file or directory

The last command brings up a blank page in the text editior.

Thanks for your advice

First of all, you probably already have it installed (in particular, if the first message told you "shorewall is already the newest version."). It helps me if you can give me the complete responses to these commands. Otherwise, I can't really help you, as I may be missing vital clues.

Secondly, that next command won't work. Maybe they meant for you to perform:


sudo cp /usr/share/doc/shorewall/examples/one-interface/* /etc/shorewall/.

The third command should work at that point.

When I use this command: sudo aptitude install shorewall
No packages will be installed, upgraded or removed.
O packages upgraded, O newly installed, O to be removed and upgraded.
Need to get OB of archives, after unpacking OB will be used.

When I use this command sudo cp /usr/share/doc/shorewall-common/examples/one-interface/* /etc/shorewall/.

CP-cannot stat. /user/share/doc/shorewall-common/examples/one-interface/* :
no such file or directory
sudo nano /etc/shorewall/rules

This last command brings up a blank page in the text editior.

At the bottom of the page there are several commands that I can use to exit, cancel etc.

Here is the web URL I am following to install this server
