It is strongly encouraged you upgrade to this release and the latest release of zerotier-systemd-manager on linux hosts if you have been using zeronsd in the past. It contains many bug fixes and improvements.
It is also important that as of this release, zeronsd has evolved to the beta stage of release testing. Please be aware it is completely usable in a lot of situations, but maybe don't run your internal facebook clone against it yet.
- hostname translation! Got a computer named
Joe's Computeryou don't want to change? Now,zeronsdwill turn that intojoes-computer.domain. Previously it would just ignore it. - many diagnostic messages were improved and logging output was also made clearer
- performance was slightly increased now that zeronsd has limited threads to the number of cpus on the host (accounting for hyperthreading). Before this number was static and low intentionally, let us know if you run into trouble with this setting. Performance increased by a factor of 300% for cache-less A record lookups of a single domain on a 24 thread machine during testing.
- Multiple listening addresses! Now, if you have a zerotier network with multiple addresses, zerotier will gladly use all of them to listen on. This feature is expected to evolve to be less coarse in the future. Note additionally, that only ipv4 DNS servers will be distributed to central to propagate to clients; IPv6 is still unsupported in zeronsd and will arrive in 0.2.0.
- Related to this change, A and AAAA records can now present round robin selection lists for hosts that have multiple listening addresses.
zeronsd supervisehad a setup bug that would sometimes cause it to not boot at the appropriate time to sync up with zerotier; thanks to @devvick for sorting this one out for us!- Finally, hosts files now refresh within 30 seconds of your edits. They are presented and updated like normal domains on the network.
Pro tip: try nmap -oG - <subnet> to list all the names on your network using Windows, OS X or Linux with zerotier-systemd-manager.
