Just stating that other approaches could work because people do not like penalty, is leading nowhere.

Never said that. I said "it seems like"... I want mathematical proof, too.

BCNext used a wrong word. Actually it's not a penalty, it's a trick to bump forging power of the other accounts back to 100%.

That sounds way more positive. Thank you, CfB. Smiley

Are you basically saying that preventing a node from forging for a period is essentially preventing a node forging or preventing an account forging.

I assume its preventing an account forging not the actual NRS instance i.e. its like the account had an effective balance of ZERO - that also explains the 24h because its 1440 blocks for an account balance to become effective again.

This would also automatically increase the forging of the remaining nodes because that NXT would not be included in the total able to forge.

Have I understood it right?

Therefore if an account was penalised you could log another account into that node and it would still have a chance to forge.

Something like that. This "penalty" is also used for other things, for example, it forces to split big accounts into smaller ones. Which in turn gives extra benefits (the small bias toward bigger accounts) to those who support "transparency" approach.

Then, excuse me. I misunderstood. 'it seems like' sounds to me like 'it's basically proven that'.

Try configure the absolute path in the configuration file client NXT.

Like html/nrs  => /mnt/nxt/html/nrs

https/ssl is not enabled by default in 0.8.x. You have to use http.

Quote from: Jean-Luc
SSL can be enabled for both the API server and the UI server (default disabled). If this is done, the corresponding ports will accept https requests only. There is no way currently to have both http and https supported at the same time, but this can be added, I just didn't see the need for it. If you enable SSL, you need to set nxt.keyStorePath and nxt.keyStorePassword, and obviously you need to have your own SSL certificate (self-signed or signed by a CA) in a keystore file. I have only tested this with a self-signed certificate.

How to upgrade your NXT node guide.

Step 1) Log in to your node using Putty (user 'root' and pass that your received in the welcome email from your VPS company).

Step 2) Enter the following commands in the terminal:

1) 'top' command, it will show a line similar to this for 'java' process:

2973 root       20   0 1166m 428m  10m S   0.0 41.8   9:57.51 java


2973 is your process ID.


press 'q' to exit top;

2) kill -9 2973      (kills the java process, enter your 'java' process ID number instead of 2973).

3) cd    (switch to your home directory);

4) rm nxt.zip   (delete the old nxt.zip file);

4a) rm -rf /root/nxt.old   (this removes the old nxt working directory if it's not the first upgrade you do);

5) mv nxt nxt.old   (rename the old nxt working directory);

6) wget http://download.nxtcrypto.org/nxt-client-0.8.3.zip

7) unzip nxt-client-0.8.3.zip

8 ) cat ~/nxt.old/webapps/root/WEB-INF/web.xml   
(this lists the contents of the old config file, copy-paste your myAddress and myHallmark parameters from it into a text file on your PC, if you hadn't saved them earlier.

9) nano conf/nxt-default.properties

a) in the section  ###PEER NETWORKING ###, find the following lines:

Code:
nxt.myAddress=
put IP address you got from the host.

It should look like:

nxt.myAddress=x.x.x.x

b)
Code:
nxt.myHallmark=
if you use a hallmark on your node, put your hallmark there (make sure no whitespace character is left in it when you copy-paste it)

press CTRL+X and then Y to save the file.

Code:
10) cd ~/nxt

11) nano run.sh

a) If your VPS has 512 MB RAM, replace the line:

java -Xmx1024M -cp nxt.jar:lib/*:conf nxt.Nxt

with

java -Xmx450M -cp nxt.jar:lib/*:conf nxt.Nxt

b) If your VPS has 1024 MB RAM, replace the line:

java -Xmx1024M -cp nxt.jar:lib/*:conf nxt.Nxt

with

java -Xmx800M -cp nxt.jar:lib/*:conf nxt.Nxt

-----

press CTRL+X and then Y to save the file.

12)
Code:
nohup ./run.sh &

13) run
Code:
top
  to show running processes, check that you see process 'java' running and using CPU and RAM, if it is, then press 'q' to enter 'top'.

14)
Code:
exit
