Marked node doesn't need an unlocked account. But a node with unlocked account doesn't get a hallmark automatically (in current implementation).
OK, this is good. So I can unlock and mine on a node that is not public, and use a separate public node with a hallmark. Even if the public node (which presumably attracts a lot of unwanted attention) gets hacked, my private key has never been there, even only in memory, so my account is safe.

So if I run a local client should I make all these steps?
If I use a bootstrap node am I more vulnerable to attacks?
Is ur local client visible from the outside? Does it have static IP or domain? If "yes" then "yes".
What do u mean "If I use a bootstrap node"?
Have no idea thus probably not Tongue
You were saying about bootstrap nodes earlier, I though that it is the same as having static IP/domain..

Correct. U could even mark nodes of ur friends with ur hallmark, if u believe they won't attack the network.

I think it's the SHA of an old version. You have daily client updates and the initial posting is only updated every 3-4 days.

HOST_WEIGHT - "weight" of the host, u can have a lot of hosts marked with the same account, weight defines what part of the balance will be used (weight/Sum_of_all_weights). If u have only 1 node then it will use 100% of the balance
...
An example:
_ttp://localhost:7874/nxt?requestType=markHost&secretPhrase=123&host=88.198.210.245&weight=1000&date=2013-12-07
- doesn't I need to write "weight=100" if I have only 1 node ?
It seems, that weight=1000 doesn't make sence anyway...

EDIT: have v.0.3.15 installed, but such query returns:
Code:
{"errorCode":7,"errorDescription":"Not allowed"}

Looks like 0.3.15 on my computer can't load blocks. It load blockchain when start up to actual date, and then show "Catching up..." constantly. There are no errors in console.

@ ImmortAlex
my 0.3.15 (Win7) can load blocks, and even can forge.
But can't calculate hallmark.

To automate the updating of the NXT client (on Linux) I wrote a small bash script.
Hope it may be useful for some of you:

Code:
#!/bin/sh

echo "should be run from one level above 'nxt' directory"
pkill -9 java
mv nxt nxt_old
wget https://dl.dropboxusercontent.com/u/67242472/nxt.zip && unzip nxt.zip && cd nxt
xmlstarlet ed -u "/web-app/servlet/init-param[param-name='myAddress']/param-value" \
        -v YOUR_IP_ADDRESS webapps/root/WEB-INF/web.xml > web.xml
mv web.xml webapps/root/WEB-INF/web.xml
mv ../nxt_old/*.nxt .
rm -rf ../nxt_old
rm -rf ../nxt.zip
java -ms256m -mx512m -jar start.jar &
echo "-------------   UPDATED   ------------"
exit 0

Replace YOUR_IP_ADDRESS with your actual IP address, store it as nxt_update (for example) and then run it as
Code:
./nxt_update

Note that xmlstarlet must be installed:
Code:
sudo apt-get install xmlstarlet

But can't calculate hallmark.
Deleting peers.nxt helps me, donno why...
Edit: no. It stop again.


I calculated hallmark without problems. Hope my small funds help the network.

hat runs Nxt soft. U can bypass this step if u already know ur host.

3. Do such a request: http://localhost:7874/nxt?requestType=markHost&secretPhrase=MY_SECRET&host=MY_HOST&weight=HOST_WEIGHT&date=CURRENT_DATE

MY_SECRET should be replaced with the secret phrase of ur account (more coins it has - better it is)
MY_HOST - ur host
HOST_WEIGHT - "weight" of the host, u can have a lot of hosts marked with the same account, weight defines what part of the balance will be used (weight/Sum_of_all_weights). If u have only 1 node then it will use 100% of the balance
CURRENT_DATE - a date in "yyyy-mm-dd" notation. Use the same date for all ur nodes. If u use other date then all hallmarks set in the past will be invalidated.

An example:
http://localhost:7874/nxt?requestType=markHost&secretPhrase=123&host=88.198.210.245&weight=1000&date=2013-12-07

WHOA.  Are you actually suggesting that we put our secret passphrase, in plain text, into the URL of an http request?

I'd never do that....!!!

EDIT: have v.0.3.15 installed, but such query returns:

U can use any weight from 1 to 1000000000. It does make sense if u want 1 node to be 1000x more "heavy" than others.

"Not allowed" is sent if "allowedBotHosts" set.
