It will probably work on other 64-bit architectures as well. Patches for ttcp and the ebuild are attached. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 28068 [details, diff] patch to ttcp that adds patch application to src_unpack
Created attachment 28069 [details, diff] Patch that makes ttcp 64-bit clean(in theory).
have you tried this with nttcp? Description: New version of ttcp -- Tool to test TCP and UDP throughput
No sorry I haven't messed with nttcp. Though I did also fix up the Windows version of ttcp that I got from the Cygwin project. Are there any advantages to nttcp that would make it worth taking a look at? The main reason I grabbed/fixed ttcp was that I recently put together a small gigabit LAN and needed a non file copy based method for testing throughput as I tweaked things. On another note I've tested the patched version of sgi-ttcp.c on an x86 gentoo box and it works fine there as well. I've also modified my copy to print out the actual size of the SO_SNDBUF and SO_RCVBUF parameters. Not sure if anyone would be interested in that?
well, I've havent really made use of either one and they both appear to be dead development-wise... but there's only so much development one can do on an app like ttcp that doesn't involve porting anyway. :) list of improvements (from the nttcp page): * Ported to varity of systems (HPUX, AIX, IRIX, OFS/1, SunOS.4, SunSolaris 5.*, [Free,Net]BSD). * Can be started via inetd; you need not be logged in on the remote side to make transfers to this machin. * Output can be customized on commandline * Different commandline options for the remote side in one call * Measures on boths sides of the connection and reports both measurements on the calling side. * Can checksum the traffic, to detect data failures in UDP transmissions * sending of multicast pakets. anyways, I was just curious about nttcp. also, both nttcp and ttcp compile without problems here... could you provide me with additional information about what you mean by 64bit clean? ayanami ttcp # ttcp -t -s localhost ttcp-t: buflen=8192, nbuf=2048, align=16384/0, port=5001 tcp -> localhost ttcp-t: socket ttcp-t: connect ttcp-t: 16777216 bytes in 0.05 real seconds = 327647.24 KB/sec +++ ttcp-t: 2048 I/O calls, msec/call = 0.03, calls/sec = 40955.90 ttcp-t: 0.0user 0.0sys 0:00real 0% 0i+0d 0maxrss 0+2pf 339+1csw ayanami ttcp # nttcp -s localhost l 8388608 0.13 0.05 519.6356 1428.0912 2048 15858.02 43581.9 1 8388608 0.13 0.08 519.0288 818.5305 2049 15847.24 24991.8 I will mark both applications as testing on amd64 as they are, and I'll leave this bug open until you can explain to me what I'm missing here.
The "big" problem was in the buffer alignment code. It was casting a pointer to an int which on a 64 bit machine would truncate it to 32 bits. The other main problem was many printf format statements that specified an int when the arguement was a long int. I.e. I changed a bunch of %d format specifiers to to %ld. I also cleaned up all but one warning when it is compiled with the -Wall flag. Specifically with the original version gcc -Wall sgi-ttcp.c prints the following warnings: sgi-ttcp.c:151: warning: return type defaults to `int' sgi-ttcp.c: In function `main': sgi-ttcp.c:159: warning: implicit declaration of function `getopt' sgi-ttcp.c:183: warning: implicit declaration of function `atoi' sgi-ttcp.c:229: warning: implicit declaration of function `bzero' sgi-ttcp.c:244: warning: implicit declaration of function `bcopy' sgi-ttcp.c:263: warning: implicit declaration of function `malloc' sgi-ttcp.c:263: warning: cast to pointer from integer of different size sgi-ttcp.c:266: warning: cast from pointer to integer of different size sgi-ttcp.c:288: warning: passing arg 2 of `bind' from incompatible pointer type sgi-ttcp.c:329: warning: passing arg 2 of `connect' from incompatible pointer type sgi-ttcp.c:351: warning: passing arg 2 of `accept' from incompatible pointer type sgi-ttcp.c:356: warning: passing arg 2 of `getpeername' from incompatible pointer type sgi-ttcp.c:396: warning: implicit declaration of function `read' sgi-ttcp.c:401: warning: implicit declaration of function `write' sgi-ttcp.c:430: warning: int format, different type arg (arg 4) sgi-ttcp.c:436: warning: unsigned int format, pointer arg (arg 4) sgi-ttcp.c:438: warning: implicit declaration of function `exit' sgi-ttcp.c: At top level: sgi-ttcp.c:463: warning: return type defaults to `int' sgi-ttcp.c: In function `pattern': sgi-ttcp.c:472: warning: control reaches end of non-void function sgi-ttcp.c: In function `read_timer': sgi-ttcp.c:567: warning: implicit declaration of function `strncpy' sgi-ttcp.c: In function `prusage': sgi-ttcp.c:617: warning: int format, different type arg (arg 3) sgi-ttcp.c:617: warning: int format, different type arg (arg 4) sgi-ttcp.c:623: warning: int format, different type arg (arg 3) sgi-ttcp.c:623: warning: int format, different type arg (arg 4) sgi-ttcp.c:645: warning: int format, different type arg (arg 3) sgi-ttcp.c:651: warning: int format, different type arg (arg 3) sgi-ttcp.c:658: warning: int format, different type arg (arg 3) sgi-ttcp.c:663: warning: int format, different type arg (arg 3) sgi-ttcp.c:668: warning: int format, different type arg (arg 3) sgi-ttcp.c:673: warning: int format, different type arg (arg 3) sgi-ttcp.c:678: warning: int format, different type arg (arg 3) sgi-ttcp.c:683: warning: int format, different type arg (arg 3) sgi-ttcp.c:688: warning: int format, different type arg (arg 3) sgi-ttcp.c:688: warning: int format, different type arg (arg 4) sgi-ttcp.c: At top level: sgi-ttcp.c:747: warning: return type defaults to `int' sgi-ttcp.c: In function `Nread': sgi-ttcp.c:755: warning: passing arg 5 of `recvfrom' from incompatible pointer type sgi-ttcp.c: At top level: sgi-ttcp.c:778: warning: return type defaults to `int' sgi-ttcp.c: In function `Nwrite': sgi-ttcp.c:785: warning: passing arg 5 of `sendto' from incompatible pointer type sgi-ttcp.c: In function `delay': sgi-ttcp.c:806: warning: passing arg 2 of `select' from incompatible pointer type sgi-ttcp.c:806: warning: passing arg 3 of `select' from incompatible pointer type sgi-ttcp.c:806: warning: passing arg 4 of `select' from incompatible pointer type sgi-ttcp.c: At top level: sgi-ttcp.c:39: warning: `RCSid' defined but not used Whereas on the patched version it only prints: sgi-ttcp.c:39: warning: `RCSid' defined but not used I'll take a look at nttcp. Having it running as a service would sure make it more convenient to use.
sorry it took so long, i got distracted
