Python TCP.dstport Examples

Example #1

# of the application

# dropping unnecessary priviliges
umit.umpa.utils.security.drop_priviliges()

# create new IP object
ip = IP()
# setting some fields
ip.src = "127.0.0.1"
ip.dst = "67.205.14.183"

# the same for TCP
tcp = TCP()
# setting some fields
tcp.srcport = 2958
tcp.dstport = 0

# also, SYN flag will be set up. here SYN
tcp.set_flags('flags', syn=True)

# create payload object and set the data while calling constructor
payload = Payload(data="something here")

# create a new packet and include one protocol (ip)
packet = umit.umpa.Packet(ip)
# packing another protocol into our packet
packet.include(tcp, payload)

# creating new socket connection
# NOTE: we need to raise our priviliges.
# we can call super_priviliges() function and pass function which need these
