    What exactly do you want to check, incoming/outgoing connections or the bandwidth usage? Usually, the "netstat" command is used to check both incoming and outgoing network connections. Also, the command "iftop" is used to display the current list of network connections ordered by bandwidth usage.

    Linux has an utility called netstat, You can run the following command to check the network connections, interface statistics etc.

    List all ports : netstat -a
    List all tcp ports : netstat -at
    List only listening ports : netstat -l
    List only listening TCP Ports : netstat -lt
    List only the listening UNIX Ports : netstat -lx
