Chapter 15: Network Encapsulation with Remote Procedure Calls (RPCs) |
|||
|
|
Time Server | Makefile.rpctime | This is a very simplified program that demonstrates passing scalar (simple) variables through an RPC connection. The rpcgen program creates all files from the .x file. |
|
|
rpctime.h | ||
|
|
rpctime.x | ||
|
|
rpctime_client.c | ||
|
|
rpctime_clnt.c | ||
|
|
rpctime_server.c | ||
|
|
rpctime_svc.c | ||
|
|
Process Table Server | Makefile.rpcproc | This program extends the types to include strings. The program's server opens a pipe to 'ps' and sends the resulting strings to the client. The new XDR file helps with data type conversion. |
|
|
rpcproc.h | ||
|
|
rpcproc.x | ||
|
|
rpcproc_client.c | ||
|
|
rpcproc_clnt.c | ||
|
|
rpcproc_server.c | ||
|
|
rpcproc_svc.c | ||
|
|
rpcproc_xdr.c | ||
|
|
Linked List Server | Makefile.rpclist | The rpcgen program allows you to create dynamic data types and send them over the communication link. It has some interesting limitations, though, which the book covers in detail. |
|
|
rpclist.h | ||
|
|
rpclist.x | ||
|
|
rpclist_client.c | ||
|
|
rpclist_clnt.c | ||
|
|
rpclist_server.c | ||
|
|
rpclist_svc.c | ||
|
|
rpclist_xdr.c | ||
|
|
List-Process Table Server | Makefile.rpcps | This program merges the list and proc-table programs to create a fielded, dynamic memory process information query. |
|
|
rpcps.h | ||
|
|
rpcps.x | ||
|
|
rpcps_client.c | ||
|
|
rpcps_clnt.c | ||
|
|
rpcps_server.c | ||
|
|
rpcps_svc.c | ||
|
|
rpcps_xdr.c | ||
|
Chapter 16: Adding Security to Network Programs and SSL |
||
|
|
ssl_client.c | The SSL (with the OpenSSL API) client/server uses the standard socket interface as the starting point, and then, it does the handshaking for a secure connection. |
|
|
ssl_server.c | |
|
Chapter 17: Sharing Messages with Multicast, Broadcast, and Mbone |
||
|
|
bcast_client.c | Broadcasting, an older method of sharing information uses the network mask to send and receive general messages. Multicast replaces broadcast as a more WAN-friendly solution. Until multicasting is fully supported on the Internet, Mbone acts as a virtual network using IP-over-IP protocols. |
|
|
dgram_echo.c | |
|
|
mcast_client.c | |
|
Chapter 18: The Power of Raw Sockets |
||
|
|
myping.c | Raw sockets permit you to experiment with nearly zero-level protocols, simplifying custom protocols. |
|
|

|
|
ping.c | |
|
Chapter 19: IPv6: The Next Generation to IP |
||
|
|
client_v6.c | When written right, converting to IPv6 from IPv4 is very simple and only requires a few changes. These examples show the few changes in socket creation and setup. |
