This directory contains a set of network tests and demonstrations programs.
| Directory | Description |
|---|---|
| netdemo | simplest test, echos data on sockets |
| dnstest | test of DNS client |
| http | test of GoAhead web server |
| netlink | link only test to evaluate code space requirement of network stack, ftpd, and httpd |
| ntp | test of network time protocol client |
| rpc_demo | test of RPC library |
| select | test of select() routine functionality |
| tftpTest | test of TFTP (Trivial FTP) client filesystem |
| ttcp | TTCP throughput test |
The file networkconfig.h MUST be configured to reflect your local
network according to the included Configuration Notes.
-
Make sure you change the definition of MY_ETHERNET_ADDRESS in networkconfig.h before you try to use any of the network demonstration programs.
-
If you do not use BOOTP (i.e. the
#define USE_BOOTP 1in init.c is removed), make sure you change the definition of MY_INTERNET_ADDRESS before you try to use the programs.
FAILURE TO FOLLOW THE ABOVE INSTRUCTIONS MAY PROVOKE YOUR NETWORK ADMINISTRATOR TO THE POINT WHERE VICIOUS ATTACKS WILL BE MADE UPON YOU.
For debugging, I'd suggest breakpoints in the socket receive and transmit
tasks to trace where you're running. Also, if you have a LANalyzer or
workstation with snoop capability set it up to show all packets to/from the
hardware (Ethernet) address of your target machine.
On Linux, you can use the tcpdump utility to examine packets. Something like this:
tcpdump -i eth0tcpdump can filter packets. See the man page for details.
This set of tests is intended to demonstrate the capabilities of the RTEMS port of the FreeBSD TCP/IP stack. In addition, these tests can be used to test a network device driver.
