To start an XXX server, you can use the following command:

rft -s [-t <port>] [-p <p>] [-q <q>] [-v]

To start an XXX client and connect to a server, you can use the following command:

rft <host> [-t <port>] [-p <p>] [-q <q>] [-v] <file> ...

• -s: Starts the program in server mode
• <host>: Specifies the hostname of the server, the client wants to connect to
• -t: Specifies the port of the server. If no port is specified, the default port 2020 is used
• -p/-q: Specifies the loss probabilities for a Markow-chain model. If only one is specified, p=q is assumed. If neither is specified, p=q=0 is assumed
• -v: Starts the client/server in verbose mode
• <file>: Specifies one multiple files the client wants to download from the server
