# countryblock.sh -- yet another country blackholing script by morb

CC=$1;[ -z $CC ]&&printf "Usage: $0 <country code>\nex:\n$0 cn #China\n"&&exit 1
[ "$USER" != "root" ]&&printf "root required.\n"&&exit 1
ZONE="http://www.ipdeny.com/ipblocks/data/countries/${CC}.zone"
curl -s $ZONE | xargs -I, ip route add blackhole , metric 999

I added the if statement to take the option "list" and it will print all available codes from the commandline so you don't have to visit the site. The SSL cert expired so used -k.

if [[ "${CC}" == "list" ]];
then
	curl -k -s https://www.ipdeny.com/ipblocks/ | egrep -o '[A-Z].*\([A-Z]{2}\)\ ' \
| sed 's/([A-Z]\{2\})/:&/g' | column -t -s : | more

fi

cool

check this out

$ awk '{FS="\t";print $1, $5}' /usr/share/libtimezonemap/countryInfo.txt
$ awk '{FS="\t";print $1, $3}' /usr/share/zoneinfo/zone.tab | sed '/^#/d'

That would work too, but there are some county codes (14) in the zone.tab that are not on the ipblocks website.
