Hello Stuart ! Thank very much !

How about a simpler test where you change fewer variables (and don't involve the speed of disks on the machines)?

Re: bandwidth problem
Interesting Rick, I will do tests setting auto on ubiquity, My doubt ... Why windows vista on both sides have speed up to 10mb/s when a do an download ? ( I put 2 windows boxes with smb ) if I set auto on both sides ( on openbsd boxes ) the speed is 1.8mb/s and if I set 100baseTX ( Half ) the speed is the same Regards, 2011/3/16 Rick Ballard > The Ubiquity is likely an unmanaged device, it probably does auto only or > is > at least configured for auto.

Re: bandwidth problem
The Ubiquity is likely an unmanaged device, it probably does auto only or is at least configured for auto. When the obsd box is set to full duplex, the auto negotiation fails on the Ubiquity box and defaults to half duplex, resulting in the poor bandwidth. When the obsd box is set to auto, auto negotiation succeeds on both sides, and we get full duplex on both sides. This is normal behavior.

Thanks Mark I checked this on AP's and it are enabled, The structure is : OBSD 1-AP-AP___APAP--OBSD2** |___ AP 2 and 3 are linked with Cable ( Ubiquiti *Rocket M5 ) four AP's The cable are plugged direct on OpenBSD Boxes, without switches, but as i said on AP's are enabled * 2011/3/16 Mark Felder > On Wed, 16 Mar 2011 13:30:21 -0500, R0me0 *** > wrote: > > Please, someone can indicate the right direction to resove this ? >> > > The first step in troubleshooting this is checking the switch or router > your OpenBSD machine plugs into.

Re: bandwidth problem
With the tests that I do, I think that is something with full-duplex, because if I set ifconfig media 100baseTX on both side, I have the same speed that media autoselect ( and this is 100baseTX full-duplex ) But the download speed not is as windows boxes ( 10mb/s ) is 1,8mb/s Regards, > >> The list is going to ask you for some of these points: > http://www.openbsd.org/report.html > > -luis

doing this:
./configure CFLAGS=-lz
gets me (on my i386/3.7 GENERIC) past the error Miroslav has, but now
it's bailing with:
checking for gdImageCreate in -lgd... no
configure: error: Bandwidthd requires but cannot find libgd
Given that I have both p5-GD and gd-1.8.3 installed from ports for
other needs, I think I have all the requisite libs.
Now the pertinent part of my config.log:
configure:2923: $? = 1
configure: failed program was:
#line 2901 "configure"
#include "confdefs.h"
/* Override any gcc2 internal prototype to avoid an error. */
#ifdef __cplusplus
extern "C"
#endif
/* We use char because int might match the return type of a gcc2
builtin and then its argument prototype would still apply. */
char gdImageCreate ();
int
main ()
{
gdImageCreate ();
;
return 0;
}
configure:2940: result: no
configure:2950: error: Bandwidthd requires but cannot find libgd
Lastly, even though this is really a bandwidthd issue and not an
OpenBSD issue, I was hoping another hint or two from misc@ and we'd be
off to the races with this app
Thanks much,
Kevin
