Running our first node

What we're going to do here is prepare three Jtrix applications and then run them on our own node. The preparation is creating netlet descriptors which are digitally signed with our own unique key pairs.

Here are the commands to start this from scratch, with the system's responses. First we set things up. See Section  for an explanation of this:

% hospitality_init hos01
generating hospitality for hos01...
generating key pair for hos01...
% ls hos01*
hos01-boot.xml	hos01.prv  hos01.pub
% telnet_init 2000
configuring telnet on 2000...
% ls telnet-*
telnet-2000.xml
% sas2_init sas01
generating key pair for sas01...
creating sas01 launch descriptor... 
configuring sas01...
% ls sas01*
sas01-boot.xml	sas01.prv  sas01.pub  sas01.xml
% 

Note that Hospitality is the name of Jtrix.org's implementation of a hosting service. So hospitality_init initialises the hosting service.

Now we can run the first node with a hosting service. Section  has an explanation of this:

% jnode 100 -netlet-stdio hos01-boot.xml hosting-out=hos01-admin.xml \
     telnet-2000.xml hosting-in=hos01-admin.xml \
     sas01-boot.xml hosting-in=hos01-admin.xml \
         hosting-out=hos01-real-admin.xml sas-out=sas01-warrant.xml \
         sas-desc=sas01-real-desc.xml

At the end the prompt does not return, since the node is running. Notice the lines that begin netlet:XXX.0.1. That XXX is the node ID we chose on the command line. We should make a note of it for later.

Also, make sure you leave the node running in its own window; don't ``background'' it. It will continue to produce all kinds of output, and you don't want that to interfere with any other things we're going to.

Starting the node with these applications also produced some more files. Here is everything we have so far:

% ls hos01* telnet-* sas01*
hos01-admin.xml       hos01.prv       sas01-real-desc.xml  sas01.pub
hos01-boot.xml        hos01.pub       sas01-warrant.xml    sas01.xml
hos01-real-admin.xml  sas01-boot.xml  sas01.prv            telnet-2000.xml
