Hello all:

I'm about at about an intermediate level with Ubuntu, but completely new to servers. I followed this tutorial to set up Ubuntu Server 9.10 on my Lenovo R61i. All went well up until the installation of the firewall.

I can't seem to install Shorewall. I typed

sudo aptitude install shorewall
and it seems to have installed fine, but when I try to backup the configuration file:

sudo cp /usr/share/doc/shorewall-common/examples/one-interface/* /etc/shorewall/
I get
cp: cannot stat `/usr/share/doc/shorewall-common/examples/one-interface/*': No such file or directory
I can't find any evidence that Shorewall is even installed. What am I missing?? I googled the problem, and haven't seen anyone else with this issue.

Please help! Let me know if any more info is required.
