okay if i fill in:

nxt.myAddress=(my ipadress)
nxt.apiServerHost=0.0.0.0
nxt.allowedBotHosts=*

It should be good?

Yes. I've updated the post to clarify that step. I see now that the 12.34.56.78 was somewhat confusing.

Thanks,

I start over from the beginning of the tutorial.
I think i make some more faults

When i say exit i can't save this

.

kind regards,

Hi,coretechs
If start run.sh without using nohup command ,and when i close putty,seems the NRS/Forger will be closed too,right?

The problem is I can not start run.sh with

Code: [Select]

nohup ./run.sh &
Any suggestion?
Thanks.

Why can't you use nohup ?
Otherwise, you could try screen.

@CoreTechs

Have you tried upstart to run NXT?
We used to use god in the past to both auto start NXT at server start and to keep it up once it dies for whatever reason.

But recently we've switched to upstart and i'd recommend it to anyone.
The idea is you create an `upstart` script for NXT (see example below) the script should be put here /etc/init/nxt.conf then you can simply `start nxt` or `stop nxt` and when it dies it's restarted.

The link points to a part of our chef setup that we use to manage all our servers from but if you remove the parts between `<% if node[:ssmtp] then %>` and `<% else %> ` you'll end up with a simple upstart for NXT. The parts you'll remove are the bits we use to get notified through email whenever one of our nodes goes down.

https://github.com/fimkrypto/fimk_chef_repo/blob/master/cookbooks/nxt/templates/default/nxt.conf.erb
[the erb extension is a ruby thing used in chef, the file should be named nxt.conf]

verymuchso · « **Reply #25 on:** February 03, 2016, 01:36:29 pm »

Just realized we compile our NXT ourselves (since we use NXT+) so this part..

Code: [Select]

exec java -cp nxt.jar:lib/*:conf nxt.Nxt
is incorrect, it will not work for standard NXT distributions.

use this way to start standard NXT instead

That should work and run in the background. You can confirm by watching the nxt log file:

Code: [Select]

tail -f ~/nxt/logs/nxt.log
Personally I recommend using screen instead of running it as a background job w/nohup. I included instructions in the blog article near the bottom. With screen, you would instead run:

Code: [Select]

screen -mS nxt ./run.sh
This would start the Nxt server in a screen session named "nxt". You can then detach from the screen if you press CTRL-A, D and safely exit putty. The screen will run in the background, so you can reconnect later and re-attach to the screen by typing:

Code: [Select]

screen -r nxt

- I believe " CTRL-A then 'd' " (detach screen from terminal).

Forgive my ignorance. I'm new in the world of cryptocurrencies and my knowledge and understanding are still pretty incomplete.
My question is: NXT being pre-mined and NXT holders getting rewarded on a POS system, running a dedicated node as explained in this tutorial would benefit the host in some way or it would be exclusively to the purpose of helping and offering support to the NXT community?

Thanks

If you run a Hallmarked node you can earn NSC, which you can then sell for NXT if you wanted to

Is there a way to calculate profitability?

Hmm, this doesn't really tell much other than that it stopped. Didn't see this post until today, were you able to resolve?

Sorry I don't have a Windows guide. This guide is for building a dedicated Raspberry Pi Nxt server that you can access from any computer on your network. Once it's set up, you can use your Windows computer to access it from your web browser.

Hi,

First of all, thanks a ton for the tutorial. I am a total N00b and I think I got the server running (it's doing something

But, when I go to http://[IP]:7876 and try to register it gives me "Server Connection Error Not allowed." prompt. What am I doing wrong?

Thanks,
Alex

Are you try to access this from another computer than your rasperry?
If so I think you need to set the nxt.allowedUserHosts property in your config file.

The default is:

Code: [Select]

nxt.allowedUserHosts=127.0.0.1; localhost; [0:0:0:0:0:0:0:1]; so it can only be access from the same local machine.

smabuki · « **Reply #38 on:** July 06, 2016, 06:57:54 am »

Yes. I try to access it via my Mac.

I changed it to that, is that correct?

nxt.myAddress=192.##.###.###
nxt.apiServerHost=0.0.0.0
nxt.allowedBotHosts=*≈
nxt.allowedUserHosts=12#.#.#.#; localhost; 192.###.#.###; [0:0:0:0:0:0:0:1];

Doesn't work still.

When I go to [IP]:7876/test, I get HTTP error 403 / Forbidden

Thanks and sorry in advance

Hi,

I'm not sure what could be the problem.
Have you restarted the node after updating the config?
What does it work if you put an asterisk ( * ) after allowedUserHosts ?
Also, what is that ≈ character after allowedBotHosts?

On a side note, nxt.myAddress should be your public address as seen on the internet, 192.xxxxxxxx is your internal (local network) address, but I don't think that is the problem here.
