-Below is an example output.
+The last line that states <color #ed1c24>Error: Nothing to do</color> means that CentOS doesn't know where to get iperf from (not in the repositories that CentOS is aware of) then you can run the following.
+\\
+    yum install epel-release
+\\
+This will install the relevant repositories for CentOS to find iperf. Once again you can run:
+\\
+    yum install iperf
+\\
+Once installed, you can use <color #ed1c24>iperf</color> to connect to a multicast stream by using the following syntax.
+\\
+    iperf -s -u -B 239.0.200.1 -p 10001 -i 1
