     53=== Tutorial Setup ===
     54
     55Follow the steps below to gain access to the sandbox console and set up nodes with appropriate images.
     56 1. If you don't have one already, sign up for a [https://www.cosmos-lab.org/portal-2/ COSMOS account]
     57 1. [wiki:/GettingStarted#MakeaReservation Create a resource reservation] on COSMOS SB2
     58 1. [Documentation/Short/Login Login] into sandbox console {{{console.sb2.cosmos-lab.org}}}) with **four** SSH sessions.
     59 1. In **terminal 1**, make sure all the nodes and devices used in the experiment are turned off. Use the following command for SB2
     60    {{{#!shell
     61    omf tell -a offh -t sdr1-s1-lg1,sdr1-md1,rfdev2-1,rfdev2-2,srv1-lg1
     62    }}}
     63 1. Load {{{To_be_updated}}} on the server. 
     64    {{{#!shell
     65    omf load -i To_be_updated -t srv1-lg1 -r 0
     66    }}}
     67 1. Turn all the required resources on and check the status of all the resources. Use the following commands for SB2.
     68    {{{#!shell
     69    omf tell -a on -t sdr1-s1-lg1,sdr1-md1,rfdev2-1,rfdev2-2,srv1-lg1
     70    }}}
     71    {{{#!shell
     72    omf stat -t all
     73    }}}
     74 1. {{{ssh}}} to the server with option -Y for using GUI for our live demo.
     75    {{{#!shell
     76    ssh -Y root@srv1-lg1
     77    }}}
     78 1. In **all the ssh sessions** for {{{srv1-lg1}}}, use the following to source the correct environment.
     79   {{{#!shell
     80   source /opt/intel/oneapi/setvars.sh --force --config="/opt/intel/oneapi/renew-config.txt"
     81   }}}
     82
     83==== Find and prepare USRPs  ====
     84* Upon logging into the server, set up the 10G data interfaces DATA1, DATA2 in **terminal 1**.
     85    {{{#!shell
     86    ifconfig DATA1 10.117.1.1 netmask 255.255.0.0 mtu 9000 up
     87    ifconfig DATA2 10.118.1.1 netmask 255.255.0.0 mtu 9000 up
     88    }}}
     89    {{{#!shell
     90    sudo sysctl -w net.core.rmem_max=536870912
     91    sudo sysctl -w net.core.wmem_max=536870912
     92    }}}
     93   After running the above commands, you should see that the data interfaces have the appropriate IP addresses assigned.
     94   {{{#!shell
     95root@srv1-lg1:~# ifconfig DATA1
     96DATA1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

     113* Run {{{uhd_find_devices}}} to make sure that both USRP N310s can be reached:
