## IPv4 and IPv6 raw sockets programming #### Introduction : Low level socket programming in C. -- #### ARP -- #### IPv4 ##### # ICMPv4: - When create a ICMP socket `socket(AF_INET, SOCK_RAW, IPPROTO_ICMP)`, the kernel will fill the Ethernet and IP header automatically. - Using ancillary data to specify the option content for only a single datagram. - More details on using ancillary data, please refer to `Linux Socket Programming by Example - Chapter 17`. | Code | Descriptions | | --- | --- | | [icmpv4_echo__icmp_socket.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv4_echo__icmp_socket.c) | Send echo request (with TTL)). | | [icmpv4_echo__icmp_socket_ancillary.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv4_echo__icmp_socket_ancillary.c) | Send echo request using ancillary data (with TTL)). | | [icmpv4_echo__raw_socket.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv4_echo__raw_socket.c) | Create a Raw socket(IP_HDRINCL) to send echo request (with TTL). | -- #### IPv6 ##### # IPv6: - Fragmentation. - Hop-by-Hop Extension Header. ##### # ICMPv6: - IPv6 sockets api [RFC3493](https://github.com/Lancher/network-programming-examples/blob/master/http://www.ietf.org/rfc/rfc3493.txt) and [RFC3542](https://github.com/Lancher/network-programming-examples/blob/master/http://www.ietf.org/rfc/rfc3542.txt). - When create a ICMPv6 socket `socket(AF_INET6, SOCK_RAW, IPPROTO_ICMPV6)`, the kernel will fill the Ethernet, IP header and ICMPv6 header chuckseum automatically. - All the fields in IPv6 header and all the extension headers can be set by `ancillary data` or `setsockopt()`. - There is No option similar to the `IPv4 IP_HDRINCL` socket option. - Using ancillary data to specify the option content for a single datagram. | Code | Descriptions | | --- | --- | | [icmpv6_echo__icmpv6_socket.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv6_echo__icmpv6_socket.c) | Send echo request (with hoplimit). | | [icmpv6_echo__icmpv6_socket_ancillary.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv6_echo__icmpv6_socket_ancillary.c) | Send echo request using ancillary data (with hoplimit). | - Neighbor Discovery [RFC4861](https://github.com/Lancher/network-programming-examples/blob/master/https://tools.ietf.org/html/rfc4861). - IPv6 Neighbor Discovery (using multicast address, IPv6 do NOT have broadcast address). - Neighbor Solicitation/Advertisement and Router Solicitation/Advertisement | Code | Descriptions | | --- | --- | | [icmpv6_ns__icmpv6_socket_ancillary.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv6_ns__icmpv6_socket_ancillary.c) | Send neighbor solicitation request (with hoplimit). | | [icmpv6_na__icmpv6_socket_ancillary.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv6_na__icmpv6_socket_ancillary.c) | Send neighbor advertisement request (with hoplimit). | | [icmpv6_rs__icmpv6_socket_ancillary.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv6_rs__icmpv6_socket_ancillary.c) | Send router solicitation request (with hoplimit). | | [icmpv6_ra__icmpv6_socket_ancillary.c](https://github.com/Lancher/network-programming-examples/blob/master/src/icmpv6_ra__icmpv6_socket_ancillary.c) | Send router advertisement request (with hoplimit). | ##### # Tunneling IPv6 over IPv4: - [RFC4213](https://github.com/Lancher/network-programming-examples/blob/master/http://www.ietf.org/rfc/rfc4213.txt). -- #### TCP4 | Code | Descriptions | | --- | --- | | [tcp4_syn__eth_socket.c](https://github.com/Lancher/network-programming-examples/blob/master/src/tcp4_syn__eth_socket.c) | Send TCP SYN packet (construct from ethernet layer). | -- #### Miscellaneous | Code | Descriptions | | --- | --- | | [getaddrinfo.c](https://github.com/Lancher/network-programming-examples/blob/master/src/getaddrinfo.c) | Use `getaddrinfo()` to identify an Internet hostname. | | [bind_dev.c](https://github.com/Lancher/network-programming-examples/blob/master/src/bind_dev.c) | Bind a socket to a network interface(eth0, eth1 ...). | | [iovec.c](https://github.com/Lancher/network-programming-examples/blob/master/src/iovec.c) | How iovec work in ancillary data. | | [get_ifs_ips.c](https://github.com/Lancher/network-programming-examples/blob/master/src/get_ifs_ips.c) | List all the interfaces and ip address. | | [get_mtu.c](https://github.com/Lancher/network-programming-examples/blob/master/src/get_mtu.c) | Retrieve MTU of a interface. | --
