##### FOR THE ARP SCANNER/SYN SCANNER #####

# Function: Get Gateway
def get_default_gateway_linux():
    """Read the default gateway directly from /proc."""
    with open("/proc/net/route") as fh: # Opens the /proc/net/route interface
        for line in fh:

                continue

            return socket.inet_ntoa(struct.pack("<L", int(fields[2], 16))) # spits out the gateway!

# Function: makerange(), gets gateway, returns the range
def makerange(gwaddr):
    SIP=gwaddr.split('.') # Splits the IP address of the gateway
    iprange = SIP[0] + '.' + SIP[1] + '.' + SIP[2] + '.0/24' # makes a new one that is the range

# Defines variable scanrange for scanner

# Faster ARP scanner. outputs list of MAC:IP as per old scanner

##### GET MORE SYSTEMINFO #####

# Gets meminfo and cpuinfo, outputs to files
getsysteminfo():
