Unable to pull github repository

[Xusheng Ai]

Hello,

I am trying to build NDN-tool on Fabric nodes, which needs to pull the resources from the github. However, when I ran git clone https://github.com/named-data/ndn-tools.git , I got the error : `Cloning into ‘ndn-tools’…
fatal: unable to access ‘https://github.com/named-data/ndn-tools.git/’: Failed to connect to github.com port 443: No route to host`

I was wondering if I miss any network setting for the nodes,

Thanks,
Best Regards,
Xusheng

Github is one of the few major sites that doesn’t work with IPv6.

• An easy way to work around this is to use a public NAT64 like this:  https://nat64.net/
• More reliable but complicated solutions can be found here: https://learn.fabric-testbed.net/knowledge-base/using-ipv4-only-resources-like-github-or-docker-hub-from-ipv6-fabric-sites
• The permanent solution is to wait for github to enable IPv6.

I would try the nat64.net option. The only real negative is that it is a free public service and could disappear someday.  In practice we have found it to work quite well.

One other option is to create a tarball of whatever you need to install and just transfer it in manually.
