Copy all the above information and paste it into your `.ssh/config` file, and do the same for all the AMs, then you can very easily login into your nodes, just by using the name that is after the `Host` attribute. 61 60 Your `~/.ssh/config` file should look like … … 75 74 IdentityFile /home/nriga/.ssh/geni_key 76 75 }}} 77 78 76 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. 79 77 {{{ … … 102 100 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 103 101 }}} 104 105 102 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''') 106 107 103 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: 108 104 {{{ … … 110 106 }}} 111 107 Notice the RTT on the packets. 112 113 108 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 114 109 {{{ … … 116 111 }}} 117 112 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? 118 114 119 115 == 7. Clean up ==
