ZeroTier Review

dafyre

@johnhooks Yeah, I have. I apologize for the lack of activity, but that surgery threw me for a bigger loop than I expected, lol. I'm back in mostly good working order today...

Anyhow, from th CLI on your controller... you should be able to:

zerotier-cli /controller/network    #this line will list all of the networks  you have created
zerotier-cli /controller/network/<nwid>/member #this line will list all of the clients in <nwid> 
zerotier-cli /controller/network/<nwid>/member/<memberid>  #gives you the details of the individual client...

{
	"nwid": "<nwid>",
	"address": "<memberid>",
	"controllerInstanceId": "<removed for security>",
	"authorized": true,
	"activeBridge": false,
	"memberRevision": 15,
	"clock": 1442507102271,
	"identity": <removed for security>
	"ipAssignments": ["192.168.251.88\/24"],

As I understand it, they are planning to release an admin tool for it soon so we won't have to keep doing the CLI stuff unless you just like it, lol.

No need to apologize! I just tried it again and it worked. I must not have waited long enough last time.

When it didn't work, I also tried
zerotier-cli -j listpeers

But it didn't list them either.

dafyre

I think the listpeers command is for listing other "nearby" controllers that can be used when necessary.

It listed all of the devices on the network, but the only IP it showed was the public WAN, and it only showed the zerotier ID.

dafyre

Your devices also won't be assigned an IP address until you have authorized them into your network.

I checked right after I ran the authorize script you wrote, but I must have needed to wait a little longer.

dafyre

@johnhooks Thanks for the heads up. I'll keep that in mind.

Thanks for the code snippets to create a network and authorize a client. I modified the PHP script to change a client IP. I disconnected my client and reconnected to be safe and client started using the new IP.

<?PHP

$secret=file_get_contents('authtoken.secret');

echo "Connecting with secret of $secret\n\r";

$networkID="aaaaaaaaaaaaaaaa";
$memberID="bbbbbbbbbb";
$NewIP=array("192.168.50.10/24");

$url="http://localhost:9993/controller/network/$networkID/member/$memberID?auth=$secret";
$networkOption=array(
 'ipAssignments'=>$NewIP
);

//echo json_encode($networkOption);

$curl=curl_init();

$curlOptions=array(
 CURLOPT_URL=>$url,
 CURLOPT_POSTFIELDS=>json_encode($networkOption),
 CURLOPT_RETURNTRANSFER=>true
);

curl_setopt_array($curl,$curlOptions);

$result=curl_exec($curl);

print_r($result);

/*
echo "Sent Data: \n\r";
print_r($curlOptions);
*/

@quicky2g Welcome to the community!

@scottalanmiller Thanks! Co-worker put me onto this article and seems like a pretty cool site. Might have to stick around

Awesome! Great to see people starting to steer others over here!

Welcome aboard & Thanks for the code update!

I'm really liking how easy it is to setup. Just want to see some security review by a trusted security person before I go ahead and roll it out. Anyone seen a review on it from someone like Steve Gibson, Brian Krebs, or the like?

If you haven't read up in the FAQ yet, check it out here: https://www.zerotier.com/tech_faq.shtml -- especially the security section.

What kind of use case are you seeing for it?

I did Wireshark on the traffic yesterday. All I saw was encrypted data inside a UDP packet. Not sure if there are any vulnerabilities or security holes in the dependent applications.

I've got two locations, one with the worst "high-speed" internet you're likely to find outside of satellite (good riddance to satellite!) 1 vm host and 1 backup target at each location. Ether XenServer or ProxMox running on the servers. I'm thinking I'll be able to manage most things at both sites with a jumpbox vm. Maybe even make xrdp available as well, tho that would be painful with the DSL connection (756kb/250kb actual measured 600kb/300kb.)

The use case I see is a primarily mobile workforce. But also something like more modern offices mostly seen on the west coast - just let anyone on the network because the network is just a connection medium. ZT over the physical is what would actually allow you access to services for the company.

ZeroTier must use some kind of compression so might help with your speed issues. I have 5mbps upload at home. Did an upload test with iPerf between my house and my work office and saw 5mbps with Hamachi:

Did the same test with ZeroTier between the same endpoints:

O.o. That'd be some crazy compression!
