[SOLVED] mpd blocks all other sound output EBUSY
I was about to write a long email, complete with some logs and config
files, and postpone it to remind me to STFW for more info on an mpd
issue I was having.
While bundling everything up, I decided to try, on a lark, commenting
out someting marked 'optional' in mpd.conf, under the assumption that
using said option would force it straight to hardware as opposed to
going through dmix.
This was caused, in my case, by blindly uncommenting the "device" entry
in the audio_output block of mpd.conf; it'd look something like this:
audio_output {
# snip
device "hw:0,0" # optional
# snip
}
Parts of the message I was writing will be left as google bait to
document a potential cause of trouble to watch out for while
troubleshooting mpd for all eternity.
---
With my laptop running Debian lenny 5.0.8, I was unable to play any
other sounds while mpd is running; an attempt to do so failed, the error
indicating blockage of the audio device (EBUSY) typical transcript is
below.
$ sudo invoke-rc.d mpd start

In /etc/profile:
# cut here
[ $BASH ] && . /etc/bash.bashrc
PS1='foo $ '
# cut here
With this method you can set PS1 to be compatible with POSIX-compliant
shells, but if the user happens to choose bash you've got the full range
of bash options available. The bash version is in /etc/bash.bashrc

Re: How does Squeeze initialize PS1 ?

[ -n $PS1 ] isn't what _defines_ a shell as being interactive. That's merely one test to determine if the shell's interactive or not. Another test would be to see if the value of $- contains 'i'. From bash(1): An interactive shell is one started without non-option arguments and without the -c option whose standard input and error are both connected to terminals (as determined by isatty(3)), or one started with the -i option. PS1 is set and $- includes i if bash is interactive, allowing a shell script or a startup file to test this state. > I can imagine that a non-empty PS1 is used as an indicator, in which Yes, it is used as an indicator, as stated above. > case whatever code that actually sets up the tty also sets PS1 to some > minimal non-empty value like a single space or a dot, but is this > actually the way it works, and where is it? It's actually the shell that sets $PS1 on startup. I don't have the bash source (or 1003.2 if it's defined there) on hand as I'm composing this offline, so I leave finding exactly where and how an exercise to the reader. While technically you CAN set PS1=' ', or even unset PS1, I wouldn't recommend it. The smallest I'd recommend setting it to is '\W:\$ ', or '\$ ' (note the trailing spaces). The former displays just the last component of your current directory, and the latter doesn't even display that, just a $ (or # if you're root) I further recommend against unsetting PS1 as without some kind of prompt you have little visual indication your current process is finished. A demonstration: bry...@esterhazy:~ OLDPS1=$PS1 bry...@esterhazy:~ unset PS1 find ~ -name "`apgwrap`" && echo done # [1] [2] done [1] apgwrap is the following: #!/bin/sh apg -a0 -n1 -m10 -x12 -MNCL -tc $(dd if=/dev/urandom bs=16 count=1 2>/dev/null) [2] the 'echo done' is there only to show when the process is finished.

Multiple, non-concurrent repositories?
I don't have Internet access from home for my laptop, so I access it from a friend's house. At home, I have a Lenny repo set up using reprepro (I'll call it homeRepo), and things install from there okay. When I have network access, I install packages from the official Debian repositories (here called debRepo), so packages can never be installed from both homeRepo and debRepo at the same time. that's all good. My problem lies in the fact that I have to edit my sources.list and update the package lists each time I change sites, so that I have access to that site's repository. I've checked the documentation, without success, for a way, without having to change config files every time I change sites, to specify "Install package foobar, preferably from debRepo, but if debRepo doesn't work, then install from homeRepo, and only if homeRepo doesn't work, then give standard failure message." I've made some progress in figuring out how to do this, but my method still has a few snags: leave _both_ the homeRepo and debRepo entries uncommented in my sources.list. The snag here comes when I see a DSA, see if I need to upgrade, and if so, update && safe-upgrade -- I get (expected) errors that homeRepo can't be found and every package in homeRepo is marked Untrusted until I update from home. (unexpected, but that's another thread) I am aware of 'aptitude install package=version' and 'package/archive'. Something that just struck me as I was composing this mail: Would it be a more effective solution to my problem (than what I'm currently using) to change homeRepo's archive name from 'lenny' to something else, then when I want to install a package from homeRepo, do 'aptitude install foopackage/somethingelse'? The way I see it, though, it wouldn't settle the update issue. As an aside, the homeRepo is mainly intended for installing packages until I can get to a network connection, at which time they'll be upgraded on my next upgrade run. -- _ Brian Ryans 8B2A 54C4 E275 8CFD 8A7D 5D0B 0AD0 B014 C112 13D0 .

Quoting Scott Gifford on 2010-02-16 14:41:14: > Is there a way to get similar behavior from a CIFS server, where a rebooted > fileserver will automatically be remounted when it comes back? Hi Scott. If my mental model of your problem is correct, then your problem can be solved by adding an entry to the Debian box's crontab, which runs a script that attempts to touch a file on the NAS. If it works, return 0. If it fails, the script should remount the CIFS share, and optionally write a warning to syslog, send a text message to an admin, or whatever your site's procedure specifies. The crontab should be fired fairly frequently to minimize downtime, but use discretion of course. To me, '*/5 * * * *' should be fast enough to limit downtime, but not so fast as to effectively DoS yourself. I've only applied minimal testing to this method, yanking the network cable to simulate an outage of the CIFS server. Works okay for me, but more testing would probably be necessary. -- _ Brian Ryans 8B2A 54C4 E275 8CFD 8A7D 5D0B 0AD0 B014 C112 13D0 .

Trial and error is an effective way to figure it out. [1] Depending on a
few factors though, it may be more instructive long-term to read the
source. I've recently been putting that philosophy to use in various

I don't know of any actual utilities to do so, but there's a handy
little pipeline that I use as a generic string-counter that, so far,
works for all files I've tried, printable or not.
$ strings $yourFile | grep -oe '$yourString' | wc -l
where $your{File,String} are the file you want to search, and the string
(actually a regex) you want to search for, respectively.
These are extremely powerful commands, and from my experience are all
fairly universal. For more information, see their relevant manpages:
strings(1), grep(1), and wc(1).

Wow, thanks for that Clive. Easier to remember, too. I just tried it in
a shell one-liner, and I used a bit less logic to parse it than other
methods I've tried in the past.
The below is for the benefit of those who are just joining this thread:
For programs that expect strftime(3) format [1] this is equivalent to
-Iseconds (which isn't even documented in date(1)'s manpage in Lenny)
date +'%FT%T%z' # the part in single quotes is passed straight to
# strftime(3) if I believe, someone correct me if
# I'm wrong, please.
A simple '%F' is equivalent to 'date -I'.

implementations (IIRC)...

From my experience, it's equally able to be parsed by software, and (IMO) easier to parse by wetware.

[SOLVED] Permission denied when changing fan speed on T23 (Lenny)
I forgot to mark my previous reply to this thread solved, silly me :)
I've also written a little script for the benefit of those who may have
a similiar problem in the future and find this via the archives or by
google. Due to the triviality of this script, I'm declaring it to be
public domain.

Re: Msn protocol
send 560116
thanks
Please see Debian bug #560116, "Pidgin 2.4.*: Can't Connect to MSN
Messenger". Apparently Microsoft have changed their MSN Messenger
protocol _yet again_ -- Several clients of mine who use Woe{XP,Vista,7}
all asked me about 'mandatory wlm updates'.
This bug is available via www at [1], or by sending an email containing
the first two lines of the body of my message to [2].
[1] http://bugs.debian.org/560116
[2] requ...@bugs.debian.org
I do not have Internet access at the time I compose this email, so the
syntax of [1] may be off. Someone correct me if I'm wrong.
Offtopic: Would it work if Roy simply forwarded this mail to [2], since
I included the commands at the beginning of the mail?

Re: Permission denied when tweaking various /proc knobs (Lenny)
Thanks, I wasn't paying attention to the 'bash' part, only to the 'permission denied' part. :> PEBKAC on my part. -- _ ASCII Ribbon Campaign Against ( ) Brian Ryans HTML E-mail and V-cards Xbrianlry...@gmail.com www.asciiribbon.org / \ GPG Public Key 0xC11213D0 Key Fingerprint: 8B2A 54C4 E275 8CFD 8A7D 5D0B 0AD0 B014 C112 13D0 signature.asc Description: Digital signature
Permission denied when tweaking various /proc knobs (Lenny)
I am attempting to adjust brightness via '/proc/acpi/ibm/brightness',
but I get permission denied if I do it via sudo -- I have to su to root
in order to do the adjustments. Log at [1].
[1]
bry...@esterhazy:~$ sudo echo up > /proc/acpi/ibm/brightness
bash: /proc/acpi/ibm/brightness: Permission denied
bry...@esterhazy:~$ su
Password:
esterhazy:/home/bryans# echo up > /proc/acpi/ibm/brightness
/* Display brightness increases */
[end 1]
I am in my /etc/sudoers file with all permissions. My /etc/sudoers file,
with comments stripped, is at [2].
[2]
Defaultsenv_reset
rootALL=(ALL) ALL
bryans ALL=(ALL) ALL
[end 2]
My sudoers seems alright as I can execute other privileged commands with
no difficulty, just not mess around with the files in /proc (those few
I've tried)
I don't think it _can_ be a permissions issue, as by my understanding,
absolutely no permission checks are applied to root by userspace --
though correct me if I'm wrong.
I tried to "sudo echo h > /proc/sysrq-trigger", and again was denied.
This led me to look in "$linux/kernel/sysrq.c", but I found nothing
useful in determining why I can't do this using sudo.
I'm left to several possibilities:
1. I'm misunderstanding some documentation somewhere (PEBKAC)
2. sudo cannot allow me to do this, possibly due to restrictions
elsewhere in the kernel [3]
3. I'm able to do this, but I'm just not looking in the right place for
how to enable it
[3] Highly unlikely, by my knowledge.
