This is identical in concept to the header length in an IP packet, except this time it indicates the length of the TCP header. Reserved These 6 bits are unused and are always set to 0. Control Flags TCP uses six control flags with each flag being a unique bit. If the bit is set to...
1. TSO feature is implemented using the hardware support. This means hardware should be able to segment the packets in max size of 1500 byte and reattach the header with every packets. 2. Every network hardware is represented by netdevice structure in kernel. If hardware supports TSO, it enab...
The header contains the sending and receiving ports, a field with the length of the packet, and a checksum. The sending UDP process attempts to send the packet to its peer UDP process on the receiving host. The application layer determines whether the receiving UDP process acknowledges the ...
(0x4) IP: Header Length = 20 (0x14) IP: Precedence = Routine IP: Type of Service = Normal Service IP: Total Length = 96 (0x60) IP: Identification = 51462 (0xC906) + IP: Flags Summary = 2 (0x2) IP: Fragment Offset = 0 (0x0) bytes IP: Time to Live = 128 (0x80) IP:...
2.35. 10. The header checksum is 16 bits in size, and this field only checks the header of the packet and not the data division. This is because every time a packet passes through a router, the router has to recalculate the header checksum (some fields, such as time to live, flags,...

tcpdump command is also called as packet analyzer. tcpdump command will work on most flavors of unix operating system. tcpdump allows us to save the packets that are captured, so that we can use it for future analysis. The saved file can be viewed by the
For an IPv6 Type 0 Routing header, flags must be either IPV6_RTHDR_LOOSE or IPV6_RTHDR_STRICT. If successful, the cmsg_len member of the cmsghdr structure is updated to account for the new address in the Routing header and the return value of the function is 0. Upon an error the...
