NANDDUMP (no replies)

I used to have a copy of nanddump but it has disappeared and can't seem to find a place to download it...

Following some code here https://openwrt.org/toh/seagate/goflexhome for doing a backup it says:

cd /tmp
mkdir backup
mount /dev/sda1 /tmp/backup
wget http://plugapps.com/os/pogoplug/uboot/nanddump
chmod +x nanddump
./nanddump -nf backup/mtd0 /dev/mtd0
./nanddump -nf backup/mtd1 /dev/mtd1
./nanddump -nf backup/mtd2 /dev/mtd2
umount /dev/sda1

but this no longer retrieves nanddump. Where can I get it? Preferably by wget http rather than wget https...
