I'm trying to install pam_tally2 since pam_tally is not working for me. I found the package here: http://manpages.ubuntu.com/manpages/..._tally2.8.html but when I download it there's no way for me install it. It's a .gz file, I tried running it with dpkg and browsing to it with the Synaptic Package Manager, and no go.

How do you install a package with a .gz extension
