Sounds like the network you're on, or firewall or network filtering software installed on your computer, prevents you from accessing rsync servers.

rsync is the default because you only have to keep as much information on your disk as the current ports collection occupies and because rsync only needs to transfer the differences over the network, not the entire thing every time.

But yes, there are several other methods possible.

One method is to download the entire ports collection over http every time you sync. The disadvantage is that you have to transfer more data over the network every time you sync. There are two sources for such a tarball: the one we produce on our server (which comes with a portindex but which might be an hour of date w.r.t. the git repository but exactly as up to date as rsync), or one generated by github (which will be completely up to date with the git repository but which does not come with a portindex so you'll be generating it on your computer). This method is described here:

Another method is to get the ports by cloning our git repository. The disadvantage is it takes up disk space equal to the entire history of the ports collection (rather than just its current state), and the portindex gets generated on your computer rather than on our server. This method is described here:
