p2p network problem #769

Hello! Recently I'm encapsulating a P2P application with nanovms. However, I met a problem as follows:

qi@qi-HP-Pavilion-Notebook:~/bdledger$ ops run -c config2.json -p 2416 -p 2401 bdledger

I looked up a lot of information, and it seems that this problem is caused by the fact that nanos does not support IPv6. After that, I noticed that the master branch of nanos supports IPv6 now. Then I compiled the master branch of 'nanos' program. I replaced these three binary files in ops home directory.

cp output/tools/bin/mkfs ~/.ops/0.1.17/.
cp output/platform/pc/boot/boot.img ~/.ops/0.1.17/.
cp output/platform/pc/bin/kernel.img ~/.ops/0.1.17/.

After that I tested it again, but I still encounter the above error. I don’t know if this error is caused by ipv6, can anyone give me some suggestions. Thanks a lot!

Hi @QiZhang1997, I can confirm that Nanos supports IPv6, the problem here is that Nanos doesn't support Netlink sockets yet, we are tracking this issue in https://github.com/nanovms/nanos/issues/453.

OK! I got it. Thanks a lot!

also @QiZhang1997 fyi - if you run ops update you can get the latest release which should be 0.1.28 - and if you ever want to use what's in nanos master - we do nightly builds and you can use that via the '-n' switch for ops run

yep! I will try it.

The issue should be fixed now in the Nanos master branch (see https://github.com/nanovms/nanos/pull/1407).
