Wake up on key press?
Hi, In order to wake up my machine from zzz, I have to reach under the desk and press the power button. Is there a way of having the machine wake up when any key is pressed? I couldn't find any relevant settings in the BIOS setup. $ cat /etc/rc.conf.local ntpd_flags= xdm_flags= apmd_flags=-A sndiod=-mplay pkg_scripts=dbus_daemon avahi_daemon dbus_enable=YES Full dmesg below.

Rust programming language
Hello May 15 2015 have been a release date for Rust 1.0. What is your opinion on Rust? Does it have any chances to be some day popular programming language? Do you think that learning Rust can be good for educational purposes?
Re: Rust programming language
Hey, I follow the development of Rust since last fall and I'm really impressed by it. It has interesting features, e.g. memory leak safety or the match idiom. It was difficult to wrap my mind around many concepts of the language but in my opinion learning Rust is worth the effort. About popularity: This is of course difficult to say but there are already popular projects, e.g. Servo which will be the new rendering engine for Firefox.

Re: swap on encrypted softraid, performance penalty?
In message http://marc.info/?l=openbsd-miscm=143181492518064w=1, Fredrik Alm fred () fredrikalm ! com asked about how to handle the swap partition when using whole-disk softraid crypto: I've seen a few 'whole disk encryption' tutorials which puts the swap outside of the partition used for the softraid encryption, since openbsd already encrypts the swap partition anyway. I assume that by putting the swap inside the encrypte d partition, there will be performance penalties because encryption is done twice? could someone shed a little light on this issue? In message http://marc.info/?l=openbsd-miscm=143185210923894w=1 dan mclaughlin thevoid () openmailbox ! org replied | where did you see those tutorials? i attempted this some months ago | (6-7) and it was not possible to have swap outside of the softraid. | i forget what the exact problem was (i should have taken better | notes...). i believe the system wouldn't boot properly, and i think | it was because the swap partition was on a different device. and later in the thread | honestly though, i don't know how the guy who wrote that tutorial got it to | work (if in fact he did...), i remember it being completely unworkable. i | think the only option was to rebuild the kernel, as you said, which really | isn't an option. In message http://marc.info/?l=openbsd-miscm=143185991125110w=1 Stefan Sperling stsp () stsp ! name replied # Keeping swap on the same disk as the root filesystem has some advantages. # For historical reasons the system expects this in various places. # More things (such as hibernate) will work out of the box this way. I can report that as of 5.6-stable/amd64, it *is* possible to have swap outside the softraid. I currently have this configuration running on a pair of Thinkpad T60 laptops, and I'm fully satisfied with it. Suspend-to-RAM works fine; I haven't tried hibernate. For this configuration, I wanted separate softraid-crypto partitions for the OS and for /home. After a few false starts, I settled on the following layout: sd0 --- | a-+- (sd1) softraid crypt, size = 44.5G || a = root 256M || d = root2 256M || e = var2G || f = var2 2G || g = usr20G || h = usr2 20G | -+- | b swap 6G | j-+- (sd2) softraid crypt, size = all remaining space || j = home --- -+- sd0 is the physical disk It has 3 openbsd-partitions: a, b, and j sd1 is a softraid-crypto disk living inside sd0a. sd1 stores all the OS partitions, currently 5.6-stable in my case. [In my case there are actually two sets of OS partitions, but at present I'm only using the a,e,g root,var,usr ones. The others are for future use as backups, in the same manner as I described (for an older OpenBSD system) in message http://marc.info/?l=openbsd-miscm=125989140407974w=1.] sd0b is the swap partition sd2 is a softraid-crypto disk living inside sd0j. sd2 stores /home. Setting this up took a little bit of tinkering, but with a bit of guru help on misc@, everything eventually came out fine. Here's the procedure that eventually worked, starting from a new-from-the-factory disk just installed into the laptop: boot from 5.6 CD Install, Upgrade, Autoinstall, or Shell -- Shell maybe type some commands so the kernel can accumulate some of entropy in the random-number subsystem fill the entire disk with random data: (-- later steps won't leak which blocks have been written) (for a big disk this may take a day or so) # dd if=/dev/arandom bs=1m of=/dev/sd0c I want to use the entire physical disk for OpenBSD: # fdisk -i sd0 # disklabel -E sd0 add partitions a @ offset 128, size 93323264 sectors, type RAID bsize 6G, type swap jsize everything-left, type RAID now create softraid-crypto sd1 # cd /dev # sh MAKEDEV sd1 # dd if=/dev/zero bs=1m count=1 of=/dev/rsd0a # bioctl -c C -r 10 -l /dev/sd0a softraid0 (enter sd1 passphrase) (enter sd1 passphrase again) This passphrase will be the boot passphrase. Now install OpenBSD from the CD into sd1, # install creating whatever OS partitions you like (in my case a,d,e,f,g,h, as noted above). Two notes about this: First, put the root partition (a) at offset 256 as per Christian Weisgerber naddy () mips ! inka ! de's super-helpful comments in message http://marc.info/?l=openbsd-miscm=141519757707447w=1. And second, don't create either a swap partition (b) or a /home partition at this point -- those will come later. Now boot the newly-installed system (this will require entering the boot passphrase, of course). Once it's up and running, edit /etc/fstab to add sd0b as a swap partition: /dev/sd0b none swap sw 0 0 Now setup up softraid-crypto sd2 to hold /home # dd if=/dev/zero bs=1m count=1 of=/dev/rsd0j # bioctl -c C -r 10 -l

5.7 bootloader hang on Toshiba Portege M400
Trying to install OpenBSD 5.7-RELEASE amd64 onto a Toshiba Portege M400, with no success - the bootloader hangs right after printing out fd0 hd0+. A (very) quick perusal of boot-related manpages doesn't suggest anything I can do to debug this, so I'm looking for suggestions. Do I need to recompile the bootloader with some debug flag set? Did I just zone out while reading the relevant part of a manpage? (FWIW, WinXP, Ubuntu 15.04 and current Sysresccd all boot OK, so I'm pretty sure the hardware is fine.) -- -Adam Thompson athom...@athompso.net

Fwd: OpenTech Conference - Saturday 13th June 2015, London
Forwarded Message Subject: OpenTech Conference - Saturday 13th June 2015, London Sent: 18 May 2015 22:16 From: Alasdair G Kergon Hi everyone, With less than a month until OpenTech 2015, we're really excited by this year's schedule. As you'll see it's a fantastic, diverse line up of talks by a whole range of people working on issues and projects that really matter. Go take a look at: http://www.opentech.org.uk/2015/schedule Highlights include: - Privacy: RIPA2 and Snowdenia - The State of the Network Address - Digital toilets: For your convenience - Selling ideas - Information Infrastructures: How do we show the thing? - The Open Rights Group at 10 years old - Open Health Care - Privacy: health (Do you know where you medical records go?) - 3 Digital Services - I cracked 1,000 UK Government websites. Stop me! - Data and policy - The national election: What happened? What's next? - The Cult of Equity All this and much, much more. Tickets are GB?5 on the door, but to make sure you get in on the day, you can pre-register here: http://www.opentech.org.uk/2015/ We're already about half booked and tickets are selling fast, so don't miss out. And don't forget to remind your friends - OpenTech is as much about the people attending, as the speakers. For those who've not been before... OpenTech is an informal, low cost (thanks Open Data Institute for sponsoring us again!), one-day conference on slightly different approaches to technology, problems and democracy. You are guaranteed a day of thoughtful, thought-provoking talks leading to lively conversations with friends. Besides the sessions, there'll be plenty of time to talk in the bar which will be open until 10pm. _Switch off, sit back and enjoy the show_ As ever, while there is technically some wifi in the building, as soon as we all show up, there will no longer be any working wifi in the building. So listen to the speakers (or your mates in the bar) rather than compulsively refreshing twitter errors, wondering if you should have gone to a different session based on the tweets sent over 3G. __Wish you'd offered a talk?___ As always, we have kept a couple of talk slots in reserve, so if there are any hot new or breaking issues you'd like to offer, that you wouldn't have offered last month, email opent...@opentech.org.uk and we can chat. If you would like to help make the day as successful as previous OpenTechs, we're also looking for a few more volunteers to help out, email opent...@opentech.org.uk. Oh, and did we mention? You can pre-register your tickets here: http://www.opentech.org.uk/2015/registration More soon, Your friendly opentech organisers http://www.opentech.org.uk/2015/ - End forwarded message -

Re: possible httpd Content-Length overflow
The problem seems to be either low-memory or i386 related. I tested on an amd64 machine with 3GB RAM, and the problem goes away with 2+ GB files. The initial machine is i386 with 512MB RAM. 1GB files work fine, but when they get stepped up to somewhere around 2GB, I start seeing the negative Content-Length. I'm not sure if this well help, but I'm using this as an excuse to upgrade the problem machine to amd64. I'll debug further or report back if the issue goes away.
Re: possible httpd Content-Length overflow
That does indeed fix the content length in the header. Thanks!

Re: df(1) shows strange Avail and Capacity info
I experienced a strange output of df(1) for the root partition. The Size is greater than Used but Avail and Capacity are miscalculated That is an incorrect assessment. There is spare space in the filesystem, only available for root, and this is how it is handled.

Re: swap on encrypted softraid, performance penalty?
dan mclaughlin wrote: in the end i found it easier to just leave it all in the softraid for other reasons in addition to that issue. as to swap encryption, i disabled it. no need to encrypt twice. to the contrary, uvm swap encrypt does a better job of expiring keys and making old data unrecoverable.
Re: df(1) shows strange Avail and Capacity info
On Tue, 19 May 2015, Theo de Raadt wrote: I experienced a strange output of df(1) for the root partition. The Size is greater than Used but Avail and Capacity are miscalculated That is an incorrect assessment. There is spare space in the filesystem, only available for root, and this is how it is handled. Yes, df is functioning correctly. It looks like you have 5% of the space on your / partition reserved for the root user. You have less than 5% of the space on / available. When you have less than the reserved amount of space available on a partition df will show greater than 100% capacity used and a negative amount of space available. It's sort of a warning. If any process that is not owned by root tries to write something to your / partition, it will fail. You can see the percentage of reserved space on your / partition with: tunefs -N / You can also see a description of this feature in the notes for the -m option in the tunefs(8) man page. -- John Merriam

TODO item #0 should be to use signify with SHA256.sig rather than checking SHA256 directly. There's an example in the man page. :) SHA-256 checks if the files were downloaded properly, but it does not check if the files are from us. signify with SHA256.sig provides both integrity and authentication. Hi Doug, Well, I relied on the fact that the installer does that anyway... but you are right, given the fact that we now have signify, it is the right approach - it is also cleaner than what I had before. Thanks for the tip! Raf

Re: possible httpd Content-Length overflow
The problem seems to be either low-memory or i386 related. I tested on
an amd64 machine with 3GB RAM, and the problem goes away with 2+ GB
files.
Does the diff below fix the issue?

Re: Robustness in ports fetch program?
On 2015-05-17, Alan Corey alan01...@gmail.com wrote: I didn't look at what FETCH_CMD was defined as by default, I just assumed defining something non-null changed it. I did notice that when it retries it's wrongly assumed there's a problem with the first source and gone to another. That's a reasonable supposition because in the majority of cases, it's correct and you do want to move on to another host. It's common to see files which are no longer present return an error page with a 200 OK response; when that happens you *have* to move on. Does every developer have perfect internet? That's very frustrating, maybe counterproductive in testing. Try a modem, you can probably find a free one. Connection interruptions and resets happen many times a day. Modem, yeah easy. Dialup ISP not so much. Per-minute connection charges in many cases too. But then back when I was on dialup I didn't get that many interruptions/resets, and when they did happen TCP sessions generally recovered. People tended to use specialist download programs for anything large though, maybe you should too?
