Nios II uCLinux repository

Hello.

I'm trying to follow Johan Granath's tutorial "μclinux on nios2 with custom hardware and kernel module" (see attachment).

I have a DE2-115 board.

When I try to clone the repositories with the following commands, git doesn't find any of them.

git clone -b trunk git://sopc.et.ntust.edu.tw/git/uClinux-dist.git
git clone git://sopc.et.ntust.edu.tw/git/toolchain-mmu.git
git clone git://sopc.et.ntust.edu.tw/git/linux-2.6.git
git clone git://sopc.et.ntust.edu.tw/git/tools.git

Anyone knows where to find substitutes?

Thanks.
