    5353Once our sliver is ready we will go ahead and configure our click routers. In this example we have 4 routers, so instead of logging into each one of them and configuring it, we are going to use remote execution and configure them from our VM.

    55 === 3a. Remote execution ===
    56 In order to figure out how to login
    57 
    58 Create a sliver and add resources. (You changed the slice name, right?)
    59 
    60 {{{
    61 omni.py createsliver -a http://www.emulab.net/protogeni/xmlrpc/am StupidSliceName click-example.rspec
    62 }}}
    63 
    64 Wait until your sliver is ready, typically a few minutes. (You can monitor your sliver with [http://protogeni.net Flack] or use omni's '''sliverstatus''' command as shown below.)
    65 
    66 {{{
    67 omni.py sliverstatus -a http://www.emulab.net/protogeni/xmlrpc/am StupidSliceName
    68 }}}
    69 
    70 When your sliver is ready, run the '''readyToLogin''' script to get login information for your nodes. Use the same aggregate manager and slice name that you used for your '''sliverstatus''' command above.
    71 {{{
    72 readyToLogin.py -a http://www.emulab.net/protogeni/xmlrpc/am StupidSliceName
    73 }}}
    74 
    75 You'll get a big chunk of information, but you're interested in the '''ssh''' command information near the end.
     55=== 3a. Login and remote execution ===
     56Run the `readyToLogin.py` script to get information about logging in to nodes. The script has a lot of output so lets put that in a file so that we can easily search for the information we want.

    110 The six lines that start with '''xterm -e ssh ...''' contain the information you need to connect to your nodes. There are six nodes in this experiment, and you will want to open a window for each. Copy and paste the commands, '''adding the -A switch to each ssh command''' as shown below. You will get six new terminal windows, one on each node of your experiment. (You should say yes if you are prompted to accept the RSA key of the remote host.)
    111

    115 
    116 The shell prompt in each of your new terminal windows will tell you the host name. The four routers in your experiment are named '''top''', '''left''', '''right''', and '''bottom'''. The two end hosts are named '''hosta''' and '''hostb'''. You may want to rearrange the windows on your screen, putting the router hosts in the locations indicated, with the end hosts off to the side.
    117 
    118 '''Tip''': If you want to login to your hosts from a different host than the one you are running Omni on, take a look [wiki:HowTo/LoginToNodes here] for some tips about how to do this.
