Detailed Description

This program tests the low-level block transfer and authentication functions.

Define Documentation

#define bufsize   8192

How much random bytes should be transfered?

#define PORT   1235

Port on which the server is listening and the client trys to connect.

#define threadid   1234

The ID which identifies the thread of the block_call() function. This value can be coosen arbitrary and is passwd to all called functions.

Function Documentation

block_call_do_test (  int    fd, int    id, unsigned int    type, char *    buf, unsigned int    size, int    term )

testfunction which ist called from block_call() if a message/datablock has received.

block_call_term_test (  int    fd, int    id )

testfunction which ist called from block_call() if a the connection terminates.

client_test_program (  char *    server, int    port, int    auth )

test0001sockts: see test0001sockts.c, Client Test Programm. The client test program generates a block of n*(bufsize) random bytes, sents theses bytes to the server, receive a block from server, invert it and compare it with generated block. BUGS: Receives only one block. If not all data ready and function resv() do noct block, data get lost. Test fails. Parameters: server  (char *) contains the server name port  (int) specifies the port on the server auth  (int) 0: normale test; 1: do authentification before run test.

main (  int    argc, char *    argv[] )

test0001sockts: see test0001sockts.c.

server_test_program (  int    port, int    mode )

test0001sockts: see test0001sockts.c, Server Test Programm. The server test program binds a port and waits for connections. If someone connects it reads n*(bufsize) bytes, invert all bits of these bytes and send all back. BUGS: Receives only one block. If not all data ready and function resv() do noct block, data get lost. Test fails. Parameters: port  (int) specify the port to bind. mode  (int) select the mode of receiving a message/datablock: 0: blocked mode, use block_receive(); 1: poll mode, poll with block_receive_poll(); 2: call function block_call_do_test() if a block is received, use block_call(); 3: call socket_accept_do_test() if someone has connected. This function calls block_call() which does the same like in 2, use socket_accept(); 4: testing authenication by using socket_md5auth(). After this do the same as in 0.

socket_accept_do_test (  int    fd, int    id, char *    pip, struct sockaddr_in    their_addr, int    term )

testfunction which ist called from socket_accept() if someone has connected.
