How to Use Iperfer

Configure and Run Iperfer as server and client on each end of the network to be measured.

1. Client Mode

   $ java Iperfer -c -h [server hostname] -p [server port] -t [time]

   • -c indicates this is the Iperfer client which should generate data.
   • Server hostname is the hostname or IP address of the Iperfer server which will consume data.
   • Server port is the port on which the remote host is waiting to consume data.
   • Server port should be in the range 1024 ≤ server port ≤ 65535.
   • Time is the duration in seconds for which data should be generated.
   • All arguements are needed to be present.

2. Server Mode

   $ java Iperfer -s -p [listen port]

   • -s indicates this is the Iperfer server which should consume data.
   • Listen port is the port on which the host is waiting to consume data.
   • The port should be in the range 1024 ≤ listen port ≤ 65535.
   • All arguements are needed to be present.

Sample Output

1. Client Mode

   sent=58629 KB rate=21.253 Mbps
   

2. Server Mode

   received=58629 KB rate=20.947 Mbps
