    http://www.okean.com/antispam/china.html

    There are a number of such lists for Nigeria, China, Eastern Europe, etc. See http://www.parkansky.com/china.htm. This idea's been around for a while, and it's been useful. Blocking them at public points like a Great Firewall would be detrimental to freedom, but most individuals and companies don't need packets coming from China or Nigeria or Romania, so the more people who know how to block this traffic from their own systems if they so desire, the better. Sure, a determined hacker will set up a VPN to hide his real point of origin, but very many attacks originate from Chinese IP addresses without an intervening proxy, so it's worthwhile making life (even just a tad) harder for the people who want to make life harder for you.

    Actually, there are a few pages that wil gelp you find blocks from rogue countries. But first on to the ethical questions--

    I'm the admin for a company with around 70 employees, we maintain our own website, and mail systems. We had been getting pounded with spam and a lot of ssh attempts.

    Before taking any action, we found that China (predominately) and Korea were the source of most of our break-in attempts and spam sources. Given that we do _some_ international business, but not there, that was an easy call. Other countries soon followed. Our criteria has been that if there is any chance that someone will travel to a particular country or if the country has useful information to be had via someone with email, we don't block. I know it sounds judgmental, but it has cut our spam/scams down by about 75%. I would prefer to block all cable access to mail, but that would potentially hurt our road warriors with SMTP-AUTH. The slippery slope comes in when you say "Screw anyone on Wannadoo or BTI or Time Warner, etc. running a mail server." I know I quit running a mail server at home just because my stuff was blocked. Our compromise is that spam sources are individually blocked (rather than by range) in places where we travel or may do business.

    Further if you have a good firewall scheme you don't have to block web access. You can block the ports that give you trouble and still allow http access if you need the Chinese comsumer market to see your site. I have found that an invaluable tool to use in conjuntion with iptables is IPSet.
    It allows for very quick processing of ranges or hashes of individual addresses.

    If you want info on blocking countries (sorry if I offend anyone) look here:
