1 /*
2 * T T C P . C
4 * Test TCP connection. Makes a connection on port 5001
5 * and transfers fabricated buffers or data copied from stdin.
7 * Usable on 4.2, 4.3, and 4.1a systems by defining one of
8 * BSD42 BSD43 (BSD41a)
9 * Machines using System V with BSD sockets should define SYSV.
11 * Modified for operation under 4.2BSD, 18 Dec 84
12 * T.C. Slattery, USNA
13 * Minor improvements, Mike Muuss and Terry Slattery, 16-Oct-85.
14 * Modified in 1989 at Silicon Graphics, Inc.
15 * catch SIGPIPE to be able to print stats when receiver has died
16 * for tcp, don't look for sentinel during reads to allow small transfers
17 * increased default buffer size to 8K, nbuf to 2K to transfer 16MB
18 * moved default port to 5001, beyond IPPORT_USERRESERVED
19 * make sinkmode default because it is more popular,
20 * -s now means don't sink/source
21 * count number of read/write system calls to see effects of
22 * blocking from full socket buffers
23 * for tcp, -D option turns off buffered writes (sets TCP_NODELAY sockopt)
24 * buffer alignment options, -A and -O
25 * print stats in a format that's a bit easier to use with grep & awk
26 * for SYSV, mimic BSD routines to use most of the existing timing code
27 * Modified by Steve Miller of the University of Maryland, College Park
28 * -b sets the socket buffer size (SO_SNDBUF/SO_RCVBUF)
29 * Modified Sept. 1989 at Silicon Graphics, Inc.
30 * restored -s sense at request of tcs@brl
31 * Modified Oct. 1991 at Silicon Graphics, Inc.
32 * use getopt(3) for option processing, add -f and -T options.
33 * SGI IRIX 3.3 and 4.0 releases don't need #define SYSV.
35 * Modified --> Nov 1996 at CERN (Daniel DAVIDS)
36 * printout of the Socket-Buffer-Sizes
37 * configured for HP-UX 9000 OS
38 * configured for Windows NT OS
39 * Modified Dec 1996 at CERN (Jacques ROCHEZ)
40 * severe cleanup
41 * addaptation to the gcc compiler (ANSI)
42 * configured for Lynx OS
43 * automatic format for the rate display (G/M/K/)bytes/sec
44 * added log (L) and more help (h) options.
45 * Modified May 1997 at CERN (Jacques ROCHEZ)
46 * removed the mes() function following err() function.
47 * changed the default port to 5010
48 * Modified jul 1997 at CERN (Jacques ROCHEZ)
49 * adapted the timing calculation in microseconds
50 * addapted the code for Vsisual C++ under NT4.0
51 * Modified aug 1997 at CERN (Jacques ROCHEZ)
52 * initialise to 0 the variables nbytes, numcalls
53 * moved the buffer pre-load outside the measured timed area
54 * Distribution Status -
55 * Public Domain. Distribution Unlimited.
56 * Modified jun 1998 at Epigram
57 * - print hash marks to indicate prograss on transmitting side
58 * - sleep between bursts of buffers
59 * - set number of buffers/burst
60 * Modified jul 1998 at Epigram
61 * - send random size buffers
62 * Modified jan 1999 at Epigram (WES)
63 * - added start and end patterns to UDP start and end packets
64 * - added handling of missed start, end, or data packets for UDP tests
