These instructions show you how to install the P2PNS implementation for Linux. Compiling for Windows is currently not supported.

1. Download and install ​OverSim according to the these ​install instructions.

2. Download the modified OpenSER SIP proxy openser-1.3.1-p2psip-20080926.tgz and extract in next to your OverSim installation:

     cd ~/sim
     tar xzf /tmp/openser-1.3.1-p2psip-20080926.tgz
   

3. Compile and install !OpenSER:

     cd ~/sim/openser-1.3.1-p2psip
     make prefix=`pwd/install` install
   

4. Edit openser-1.3.1-p2psip/install/etc/openser/openser.cfg and change the following parameters:

     listen: change this to the local IP
     mpath: change this to the module path of your OpenSER installation
            (e.g. /home/user/sim/open-1.3.1-p2psip/install/lib/openser/modules/)
   

5. Edit OverSim-20080919/Simulations/realworld/realdhtapp.ini and remove the bootstrap IP:

      bootstrapIP: replace the "10.6.0.1" by ""
   

5. Start OverSim and click on the "FAST" button:

     cd ~/sim/OverSim
     bin/OverSim -f Simulations/realworld/realdhtapp.ini 
   

6. Start !OpenSER (in a new terminal):

     cd ~/sim/openser-1.3.1-p2psip
     install/sbin/openser -f install/etc/openser/openser.cfg
   

7. Start and configure a SIP UA of your choice (e.g. ​Ekiga):

     - Set the outgoing proxy to ''localIP'':5061
       (With Ekiga: ''Edit->Preferences->SIP Settings->Outbound Proxy''
     - Create a new SIP account with an arbitrary username and the domain ''p2p'' (e.g. alice@p2p)
       (With Ekiga: ''Edit->Accounts->Add'': Account Name and User ''alice'' and Registrar ''p2p'')
     - Register the account at the local SIP proxy
       (With Ekiga: ''Edit->Accounts'': Click the checkbox next to the account, if it's not already registered)
