The point of AC3/DTS pass-through mode is that it sends what looks like 16-bit stereo audio at the S/PDIF level. It's only the receiver that, on seeing a signature bit pattern, re-interprets the data and decodes it according to AC3 or DTS. audio is not only about data transfers, it's also a clock source. AC3 data could be sent on the wire, but to make audio work at least the clock must be properly handled. So, I don't even understand how AC3 would work at all. I mean, a lot of programs (ie all using sio_onmove(3)) expect that one second of s16le at 48kHz be exactly 192000 bytes of data. If AC3 is used, that wouldn't be true anymore (AC3 is 320kbit/s iirc) and audio would be broken. And this can't be fixed without adding AC3 specific code. AFAICS, pass-through would be better outside the audio subsystem, after all AC3/DTS and friends is to transmit opaque data from one computer to another without processing it. While audio interfaces are to play and/or capture analog signals to process them. We don't use any AC3 mode for azalia(4) either and pass-through works there. I bet it only works in few special cases, probably because the clock is not involved -- Alexandre

But then again there _were_ an awful lot of those questions... I'm sure that's part of the motivation but these are now automatically and dynamically tuned now. There was some discussion about bringing them back for particular cases as an override. Not sure or can't remember what the outcome was, many would leave them on and get worse performance as a result and I think the particular case brought up was already catered for. It's in the archives. I think Claudios posts likely give the answers.

The hosts were connected with 1Gbase as I have no other 10Gbase cards.

Great, thanks. I tried it out today, but the performance wasn't exactly what I had expected. This is a dual port card, so I bridged ix0 with ix1 and ran iperf between two hosts through the card.

You could try use rdomains and route exec with a cable between the two ports to make packets go over the interfaces if you don't have another host with 10G interfaces. If you've had ppb problems with em I'd imagine they would affect ix as well if it is sitting behind the same ppb.

relayd, not more than 59 redirects?
Hi,
I'm using relayd as inbound loadbalancer for about 50 websites and
webservices, https and http. All worked fine in the past few years.
I'm on OpenBSD 4.7 Generic. Currently I've configured 59 redirects.
They are working as expected but as soon as I add another redirect in
the config the last redirect stays down forever and no checks are made
for the table (verified via tcpdump on interface).

Did you try doing it with a directory without a space in it? Not
that the space shouldn't work, but it might narrow down the problem
(as might grepping the source for that error message).
Yep, it breaks when using a name without space, but it seems that this
is only reproducible with an ssh server running on Linux:
$ ssh -V
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
So the client is on OpenBSD (also 5.8), and the server is the Linux
version. This is the environment where the bug happens.
It works fine with an OpenBSD sftp server:
$ mkdir '/tmp/my dir'
$ sftp localhost
hans@localhost's password:
Connected to localhost.
sftp put -r /tmp/my\ dir
Uploading /tmp/my dir/ to /home/hans/my dir
sftp version
SFTP protocol version 3
sftp ^D
$ ssh -V
OpenSSH_5.8, OpenSSL 1.0.0a 1 Jun 2010
$ uname -a
OpenBSD stary.dhcp.fjfi.cvut.cz 4.9 GENERIC.MP#794 i386
It also works with a linux client and obsd sevrer.
So it's probably the Linux server's problem. Indeed, grepping
the source shows that the error message appears in exactly one
place, namely
$ grep Couldn't canonicalise *
sftp-client.c: error(Couldn't canonicalise: %s, fx2txt(status));
which is
if (type == SSH2_FXP_STATUS) {
u_int status = buffer_get_int(msg);
error(Couldn't canonicalise: %s, fx2txt(status));
/* ... */
}
That's the server reporting a problem status to the client.
Trying with a Linux server:
sftp put -r /tmp/my\ dir/
Uploading /tmp/my dir/ to /home/jsta6559/my dir
Couldn't canonicalise: No such file or directory
Unable to canonicalise path /home/jsta6559/my dir
The server cannot resolve the absolute canonicalized name of the dir
to be uploaded if the dir does not already exist; it seems irrelevant
whether the dir name is nice or not (I have tried both 'dir' and 'my
dir', wit the same results).

Re: relayd, not more than 59 redirects?
Hi,
Just upgraded to 4.9 and problem is solved, now. I read in the changelog,
there was a bug till 4.8 and solved in 4.9. Moving to 4.9 was good idea
anyway as I still used 4.7 :-)
Thanks for the off-list replies...

man cp: -i versus -f

This option overrides any use of -i. -i Write a prompt to the standard error output before copying a file that would overwrite an existing file. If the response from the standard input begins with the character `y', the file copy is attempted. but that isnot what cp actually does: $ rm -f echo bar $ echo new foo $ echo old bar $ cp -fi foo bar overwrite bar? n $ cat bar old Accoording to the manpage, the '-f' should have overrided the '-i'. Instead, it asked for confirmation, which said 'n', and cp(1) did not copy foo over bar, as it still has the old content. Jan

Re: cmpci(4) and S/PDIF?
Alexandre Ratchov: I would, but there shouldn't be anything required to make it work. The point of AC3/DTS pass-through mode is that it sends what looks like 16-bit stereo audio at the S/PDIF level. It's only the receiver that, on seeing a signature bit pattern, re-interprets the data and decodes it according to AC3 or DTS. So, I don't even understand how AC3 would work at all. I mean, a lot of programs (ie all using sio_onmove(3)) expect that one second of s16le at 48kHz be exactly 192000 bytes of data. If AC3 is used, that wouldn't be true anymore (AC3 is 320kbit/s iirc) and audio would be broken. Padding, of course. A video player like MPlayer will format the AC3 or DTS audio (both of which support numerous bit rates) in such a way that the result is a 192000 byte/s stream. The data on a DTS CD is already preformatted to 176400 byte/s and just needs to be passed through. I put the disk in, cdio cdplay, and the drive, cdio(1), and azalia(4) all think they are dealing with 44.1 kHz 16-bit stereo audio when in fact it is 6-channel DTS. As designed, S/PDIF only transmits 20(!)-bit stereo audio at various sample rates. However, ISO/IEC 61937 specifies how to carry various non-PCM audio formats over S/PDIF by formatting them like a 16-bit stereo stream. This is widely implemented for AC3 and DTS, rarely for MPEG audio. And this can't be fixed without adding AC3 specific code. It is handled at the application level. Check out libmpcodecs/ad_hwac3.c in the MPlayer source. There is nothing OpenBSD-specific about this. It's the same for FreeBSD, Linux, and probably others. We don't use any AC3 mode for azalia(4) either and pass-through works there. I bet it only works in few special cases, probably because the clock is not involved And you will lose that bet. There is no theoretical reason why it shouldn't work, and in practice it does with everything I've thrown at it: * DVD audio tracks, AC3 (2.0, 4.1, 5.1; 192/224/384/448 kbit/s) and DTS (5.1; 768 and 1536 kbit/s) * DTS CD (44.1 kHz) * AC3 from digital television (2.0 and 5.1; 192/256/384/448 kbit/s) * DTS extracted from Blu-ray (at the maximum 1536 kbit/s) -- Christian naddy Weisgerber na...@mips.inka.de

But then again there _were_ an awful lot of those questions... I'm sure that's part of the motivation but these are now automatically and dynamically tuned now. There was some discussion about bringing them back for particular cases as an override. Not sure or can't remember what the outcome was, many would leave them on and get worse performance as a result and I think the particular case brought up was already catered for. It may be useful to have an override in some special cases (though it would be better to tweak the autotuning algorithm if possible), but if there is some override, these particular sysctls are tainted. People would follow copy-n-paste guides and blindly set buffers to 256k per socket connection on busy servers to improve performance and wonder why their kernels were running out of memory and crashing.

Searching for the problem I found the following Mail mentioning what might be the problem http://permalink.gmane.org/gmane.os.openbsd.tech/23877 So I tried the snapshot Kernel from June 10 but that did not solve my Problem (I did not compile the Kernel just downloaded it) My question is is anyone else experience the same problem. Or did I miss something (e.g. does one of the card not work with OpenBSD 4.9 in Host AP mode anymore. At least the ral interface worked fine in OpenBSD 4.7 in hostap mode) If more Information is needed let me. Thanks in advance Mario Kothe

Recommended PCI-E adaptor with fibre connection
Hi All, I'm looking for a new 1Gb or 10Gb PCI-E adaptor with fibre connections. Can anyone make some recommendations on a good performing adapter under OpenBSD. I see there has been a lot of work going on with the Intel ix(4) based adapters would these be the recommended cards to use in the 10Gb department? If so what have the developers been using to test/develop this driver with? -- James A.

Control of OpenBSD through a web interface

I have no clear idea regarding how to design this, in the first place I thought about a cgi script written in C which I did manage to have it say hello world at the present time, but not yet much more. There's not yet clear clues regarding how to make this peace of web interface talk to the system and I would like to make it clean by means of elegant way to deal with web page - system communication.

Without the need of a web interface, if your goal is to automate some boring tasks, you can have a look at Fabric (http://fabfile.org).

I did this for a server in a law office to allow the users to do things like kill runaway print jobs and to restart the server. httpd was *not* accessible from the internet by a rule in pf and was run as httpd -u (un-chrooted). You can write CGIs as shell scripts--you just have to send the correct headers at the beginning of the script. Use your google-fu to figure those headers out. If the jobs you need require more than simple shell scripts, you can use php or perl. In the un-chrooted environment they will give you access to *everything*. Hope that helps! Jeff

Re: Control of OpenBSD through a web interface
There are free solutions available for web-based SSH; cf. here: http://en.wikipedia.org/wiki/Web-based_SSH The way you might want to set this up is so that you might install your own chosen web-based SSH software on the same OpenBSD box that also is the one you want to access via web-based SSH. (So the actual SSH traffic then becomes traffic to localhost.) Be aware that whatever box the web-based SSH software runs on can potentially see and intercept the SSH traffic in clear text, so you want to be in control of that box. Also, be VERY aware that this -*at best*- reduces the security offered by SSH to that offered by HTTPS. (Wasn't there some news some time back that HTTPS had been defeated in some context? Does anyone remember?) Whether you are prepared to sacrifice this much security for convenience obviously is for you to decide. That said, if you do implement something like this, I'd be interested in reading your notes about exactly how and you did things. Yeah, I'm a curious feller. --regards, ropers 2011/6/15 Jean-Frangois SIMON jfsimon1...@gmail.com: Hi, I have a remote controlled machine which I manage by ssh and yet I'm in the process of making up a small web page through which basic commands can be passed.

Re: sed behavior
FWIW GNU sed also appears to have the same behaviour (different from perl).

Re: Recommended PCI-E adaptor with fibre connection
- Original Message - | Hi All, | | I'm looking for a new 1Gb or 10Gb PCI-E adaptor with fibre | connections. Can anyone make some recommendations on a good performing | adapter under OpenBSD. I see there has been a lot of work going on | with the Intel ix(4) based adapters would these be the recommended | cards to use in the 10Gb department? If so what have the developers | been using to test/develop this driver with? Anyone have any comments/problems with the following cards? The following cards look to be well supported. I'm specifically talking about the Intel Gigabit EF Dual port SX adaptor based on the Intel 82576 Gigabit Ethernet Controller. This card supports full hardware virtualization which the others don't, so I'd likely go with it even though OpenBSD doesn't do H/W virtualization. http://www.intel.com/Products/Server/Adapters/Gb-EF-Dual-Port/Gb-EF-Dual-Port-overview.htm For 10GbE the following adaptor looks to be quite good and supported using the Intel 82599 10 Gigabit Ethernet Controller http://www.intel.com/Products/Server/Adapters/X520/ethernet-X520-overview.htm -- James A.

Maybe openbsd devs should test another regexp code version ?

Tracing a bit around process(),
it looks like the first application of the s command
yields dst = x continue_to_process = b\n,
and then the second application

Maybe something is wrong here with character/pointer counting,
