    6160  Your `~/.ssh/config` file should look like

    7876  i. Login to your hosts. For each one of the myPlc hosts, open a new terminal and login to each one of them. Substitute <pl_hostname> with the hostnames of pl nodes you were given on the paper slip.

    105102   i. Figure out the last octet of the IP address of your hosts. The way these MyPLC hosts are setup, is that they have multiple subinterfaces, each configured to be part of a different IP subnet. Almost all subnets in the hosts are in the form of 10.42.Y.0/24. You will notice that for all these subnets, your host has the same last octet.  In the example above all the subinterfaces of eth1, will have an IP address that will end in '''90''' (10.42.147.'''90''', 10.42.148.'''90''')

    107103   i. Ping over 3715. After logging in to your hosts, ping from host1 to host2. Assuming that host2 has a last octet of YYY you should:
    108104   {{{
     
    110106   }}}
    111107   Notice the RTT on the packets.

    113108   i. Ping over 3716. After logging in to your hosts, ping from one host2 to host1. Assuming that host1 has XXX as it's last octet you should ping
    114109   {{{

    117112   i. Notice the RTT on the packets and compare it with the above ping.
     113   i. Look at the maps of 3715 and 3716 and locate your hosts. Is the result you are seing above reasonable? Which topology has the longer path between your nodes?
