NEM nodes: security protocols

CryptoBeliever · February 7, 2018, 7:52am

Why you need https in this case?

Daniel_Ju · February 8, 2018, 12:57am

I was hoping to host a site similar to pacnem - a token based web game platform - I have most of the foundation setup and it runs nicely locally but when I host it (currently hosted on github pages) I get the mixed content error because the nodes aren’t from a https source. From what I understand all of the nodes are currently only http? Is that correct?

I mainly make calls to the nodes to validate and perform transactions?

I’m a little stumped at the moment, any thoughts @CryptoBeliever?

CryptoBeliever · February 8, 2018, 7:58am

Ok. I understand your problem. You connect directly from browser (javascript) and your service is over https.
@BloodyRookie have we list nodes exposing API over https? Or in this case should by used some proxy (where configured is https) which points to some node?

BloodyRookie · February 8, 2018, 8:06am

No list of nodes offering https available as far as i know. Maybe ask the pacnem coders for help?

CryptoBeliever · February 8, 2018, 8:12am

@Daniel_Ju
Please ask PacNEM developers in @nemprojects Telegram channel.

Daniel_Ju · February 8, 2018, 8:12am

Thanks for the responses guys! I’ll be sure to drop a message in. I’m curious to know how they did it haha.

Hi. Were you able to find a solution to this issue? We are running into the same problem.

CryptoBeliever · July 4, 2018, 6:30am

Hi. You want find some nodes running over https or you want configure your own to support https?

chefky · July 4, 2018, 8:05am

I’d like to find public nodes that run over https. I don’t want to have to configure my own NIS server if I can avoid it.

CryptoBeliever · July 4, 2018, 8:43am

For sure:
https://shibuya.supernode.me:7891/chain/height
@marc0o should know more

chefky · July 4, 2018, 9:04am

Thanks. I forgot to say that our proof of concept is running on the testnet. Would you happen to know of nodes on the testnet running on https?

marc0o · July 4, 2018, 9:11am

These are the https nodes I discovered:

But they are all Mainnet. I think there should at least be 1 Node in Testnet running with https. But unfortunately I don’t know the address.

chefky · July 4, 2018, 1:51pm

Thanks for the info anyway.

Mohd_Nazif · December 4, 2018, 1:48am

Hye guys, sorry I am new to nem. Do you guys know how to run NIS through proxy server connection with authentication?

Thanks

CryptoBeliever · December 5, 2018, 11:03am

Hi @Mohd_Nazif could you explain what you want to do exactly? You want configure SSL?

Mohd_Nazif · December 6, 2018, 12:34am

Hi @CryptoBeliever,

Actually I want to run a NIS under a company network. However the NIS keep telling me “connection refused” whenever request synchronization block with other node.

As I know, NIS synchronization are using port 7890 and that port opened. However, the port opened are under proxy server with authentication.

CryptoBeliever · December 6, 2018, 2:19pm

@Mohd_Nazif API works over 7890 port.
@BloodyRookie for synchronization is used same port?

Mohd_Nazif · January 2, 2019, 7:26am

any update?

CryptoBeliever · January 3, 2019, 7:35pm

Could you provide file with nis log?

Mohd_Nazif · January 4, 2019, 3:13am

Note : Around 21k+ available block are sync using mobile phone instead of local network.
