Lightweight Audio-Only DLNA player
Hello, there's plenty of DLNA capable media players around, but all of them (or at least, all that I could find) are gargantuan packages with tons of functionality and dependencies that I don't need or want. This is supposed to run audio-only on a small headless SBC with a USB connected DAC, nothing else. Thanks, robert

Re: How to upgrade / compile an ARM kernel?
Thanks for the tip, I'll take my question next door.
How to upgrade / compile an ARM kernel?
Hi all, I have this old hardkernel odroid-u2 chugging away as a slow but reliable mediaserver. It's a few years old and uses a Debian Wheezy I downloaded from Hardkernel's site. I now wanted to connect a two-bay USB/SATA adapter, but the odroid only sees one of the drives. Maybe it's something else, but probably it's just due to an old kernel / udev. So I dist-upgraded to jessy but got stuck halfway because the kernel is too old (3.0.57). Soon I found out that upgrading the kernel isn't as straightforward as on i386, first because of the (probably pretty simple) uboot loader, and secondly because there is a large variety of ARM SoC flavors, each of which requires its own kernel. So any tips? Am I even on the right path that the "invisibility" of one of the SATA drives is due to the old kernel /udev? I'm willing to build a new kernel for this thing. Last time I did that was probably literally almost 20 years ago. Also I'll probably need some sort of serial adapter, as the only way I currently communicate with this thing is via ssh; i.e., if the kernel won't boot I won't know why. Any tips?

Where are WiFi passwords (WPA keys) stored?
Not in /etc/wpa_supplicant/wpa_supplicant.conf, despite suggestions in every bit of documentation that I got my hands on. In fact, that file doesn't even exist on my jessie system. Nevertheless, when I configured the WiFi network using some GUI tool in the XFCE desktop, it worked. Even after a reboot, with no desktop running, I could ssh into the system via WiFi. So there must be a place, somewhere, where the WiFi passowrd ist stored, outside the realm of some specific user. Where is it? BTW, I did find a wpa_supplicant.conf file in some deep subdir of /etc/dbus-1/... (I'm not at that computer at the moment). But that is in some XML format that has nothing to do with the syntax described in the wpa_supplicant.conf man page, and my WPA key doesn't seem to be in there. Thanks!

Re: How to run a script before shutdown?
Hi Sven, thanks, that's 99% of what I need (I'd found that thread before but didn't really read it all the way because it looked like discussion going nowhere). It still needs some tweaking, though, because it runs the backup script whenever multiuser mode is left -- no matter if it's a shutdown or reboot. In practise this doesn't make any significant difference though.

How to run a script before shutdown?
Hi all, I want to automatically start a data backup script (to USB or network drive) at each shutdown of my computer. I did some research into this and found that several people have the same problem as I do. But the threads I found petered out into discussions of several ways of doing this, working for some people and not for others. So here I am wondering if there is a canonical, proper and reliable method of doing this. The script needs to run when a shutdown (but not a reboot) is started while networking and USB mounts are still up, and (preferably) multi-user mode has turned off. Perusing the systemd documentation I found all kinds of good examples of how to start stuff in a well-ordered manner to get the system up, but for shutting down there is quite little information. How is it done? robert

OK guys,
thanks a lot for all the helpful hints. What I ended up doing is this:
- purge all pulse audio stuff
- created an .asoundrc like this:
pcm.!default {
type plug
slave {
pcm "hw:0,2"
}
}
ctl.!default {
type hw
card 1
}
I don't understand the first thing about this. I just copied this file
from somewhere. Note the "hw:0,2" part. Remember that I had to use -D
hw:0,0 with aplay to make sound work while pulseaudio was installed? Now
hw:0,2 is the way to go. Search me why.
Thanks
robert

Hi Ric, it's getting weirder: I installed pavucontrol, started it, and started mplayer in some other window. No sound on my headphones, but the little VU bar flashing. Unplugged headphones, sound came from the built in speaker. Plugged headphones back in, pavucontrol sees it and changes from "unplugged" tp "plugged in", still no sound on headphones. With aplay -D hw:0,0 it still works. OK, now trying to remove all pulse-related stuff. Thanks robert -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

I'll try that (have to install first). If it works, can I then purge all ALSA-related stuff from my system?

Hello all, I know what you're thinking. Why doesn't the guy just type the subject of this message into Google and use one of the soöutions provided. Well, I did just that.

Can't. My local "modbus" subnet must not be visible from the outside. Actually there are several production tools in use here that use similar subnets with 400+ nodes (=IP addresses) in just the manner I'm describing. There's no point in exposing all that to the outside network, and it's also a potential security and reliability issue. Just imagine a multi-million dollar tool out of production because the DHCP server is down, when all those modules need to talk to is the local controller. > You could also use another private address range like 10.x.x.x for the > Modbus devices. Yeah, I'll do something of the sort. As I said, all I need to connect to on the intranet side is a single host, so I'm sure I'll find an unused address space ;-) Thanks, robert -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

What's the mess? That the Intranet contains 192.168... addresses? Anyway, this is a big multinational corporation, and I can't have any situation where the Intranet "sees" my Modbus devices, and I can't make any assumptions about addresses being or not being in use in the Intranet. I understand that from the viewpoint of my control PC I can't have any duplicate addresses because that's how IP addresses work. That was my basic question, and it was answered. So as long as I put my modbus stuff into an IP address range that I don't need on the intranet, and I make that address space "invisible" on the intranet side using a netmask, I'm fine. > The devices on your modbus should be assign a unique IP address which > MUST NOT overlap with any other range already in use at your place.

Hello all, I'm trying to have the script (below) run automatically at each system shutdown. But it is never called, neither on startup nor on shutdown. I ran insserv on it and it worked without errors. It also seems to have the correct links installed: dh@dotcom:/etc$ find . -name '*dupba*' -printf '%p %l\n' ./rc5.d/K01dupbackup ../init.d/dupbackup ./rc2.d/S01dupbackup ../init.d/dupbackup ./init.d/dupbackup dh@dotcom:/etc$ So why doesn't this work? It used to work before I upgraded from stable to testing. I've also played with the Default-Start and -Stop levels, no change. Permissions are 755 as for all other init.d script.

Interesting: In xev, I seem to get exactly what I want -- see below
xev's dump of my first pressing AltGr, then a bunch of keys I would
like to have, then releasing AltGr.
What now? I'm stumped.

X Keyboard layout trouble
Hello all,
recently I re-activated my wife's 8-year-old laptop using debian
stable. The installation went of course quickly and hitch-free as
usual. However, what doesn't work correctly is the keyboard under X.
More precisely, the symbols accessed using the "Alt Gr" key produce
all sorts of characters, but not the much-needed []{}|. This is a
German Medion MD6100 (Aldi) laptop. I tried out several X keyboard
configurations, but they either didn't work at all or just as lousy.
The console (non-X) keyboard works fine.
By the way, I'm delighted about the performance Debian gets out of
this old veteran, even with a fully encrypted harddisk. Of course all
I use as X environment is dwm, I don't want to even think about what
this would look like with a full-blown Gnome or KDE desktop.
Thanks,
robert

How to run an X program as a different user?
Hello all, my question is already in the subject line. Also I think that I've got the basics figured out, it's just that I don't understand the details. Essentially I want user A to run a specific X app as user B. So I think I need to write a tiny shell script like this: #!/bin/sh xhost +B sudo -u B /path/to/app arg1 arg2 arg3 xhost -B I need help with two things though: One, "xhost +B" doesn't work, contrary to the manpage. "xhost +" works, granting X access to the entire Net, but who cares. This is just a home computer.

Console font turned cyan
Hello folks, I don't know when it happened but it must have been during some "aptitude upgrade" run lately: My console font turned from white to cyan. At first I thought that the red VGA signal had a bad contact, but X came up in full color. Console apps can control the color to a certain extent, but the default color is a really gross cyan which produces weird color effects on an LCD with the thni Terminus fonts. In other words, I can't live with it. Where is this controlled, and how can it be switched back to white again?

What happened to xpdf in testing?
Hello all, I've searched the Net up and down but had to realize in puzzlement that I seem to be the only one with this problem. After an upgrade from stable to testing I found that xpdf had gone. Sure enough, the page about the package "xpdf" at http://packages.debian.org/squeeze/xpdf says: "This package is intended for compatibility with previous versions of this package only. You can safely remove it from your system." OK, but where is the "xpdf" program now? The only thing with "xpdf" in its name is some virtual package called "xpdf-utils" which is provided by poppler-utils which doesn't contain xpdf.

How to activate VESA mode on boot-up?
Hello folks, recently I accidentally hosed my old kernel image (it was something that ended on -k7). The only reason I'd kept it was because I couldn't get anything but the ugly boxy 80-by-something text mode console fonts to work with the 2.6.26-x-686 line of Debian prepackaged kernels. Anyway, rather than try and go hunting for an old -k7 kernel I'd like to finally get a decent video mode working on with a current 2.6.26-2-686 (stable release). Long story short, when I put "vga=ask" in grub's menu.lst, I can't enter anything but the 80-by-something modes. I've searched the Net up and down, have tried the 0x30... modes in hex, in decimal , with the '0x' and without ... nothing. The kernel simply doesn't know any additional modes (and doesn't list them. either). What can I do? I like working in the console a lot, but I need more and better-looking characters on screen.

I am > pretty stumped as to why this isn't working for you. So am I. I found that I didn't have the console-setup installed, I installed it, and was happy to see after a reboot that midway through the boot process I got a different video mode. However, after a power cycle, everything was back at 80x25 again. Also I think that the fb modes should be available directly from the start, seeing that fb support is compiled into the kernel. Is it time to file a bug against the kernel? Remember, with the latest -k7 version from sarge everything works hitch-free. Regarding the /dev/fb* nodes: Indeed my machine uses udev, and I grepped all of /etc/udev/ for strings with "fb", "framebuffer" and such. Nothing at all. Udev doesn't seem to know about framebuffers. But I suppose that doesn't matter because the kernel should have fb support right from the start, when it doesn't even have a filesystem yet. robert -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

Re: How to change console font?
Hello there, I'm completely stumped. I'm using the out-of-the-box lenny kernel vmlinuz-2.6.26-1-686. According to the config file, ehere seem to be many framebuffer options hard-compiled into the kernel (seel below). When I set the "vga=ask" kernel option, all I get is a handful of chunky 80-by-something options. Selecting "scan" doesn't reveal anything new. All of the modes listed in the "framebuffer HOWTO" yield a "video mode unavailable" error. Yes I know I can't just enter numeric modes at the prompt, I've also tried them in the command line, decimal, hexadecimal, it doesn't matter. What's going on here? When I boot a KNOPPIX cd I get the framebuffer, so it can't be a hardware issue. BTW, on the vmlinuz-2.6.18-6-k7 I used to use mode 775 which doesn't seem to be a fb mode because it doesn't have the penguin logo. robert b...@bob:/boot$ grep 'FB.*y' config-2.6.26-1-686 CONFIG_FB=y CONFIG_FB_CFB_FILLRECT=y CONFIG_FB_CFB_COPYAREA=y CONFIG_FB_CFB_IMAGEBLIT=y CONFIG_FB_DEFERRED_IO=y CONFIG_FB_BACKLIGHT=y CONFIG_FB_MODE_HELPERS=y CONFIG_FB_TILEBLITTING=y CONFIG_FB_PM2_FIFO_DISCONNECT=y CONFIG_FB_VESA=y CONFIG_FB_EFI=y CONFIG_FB_NVIDIA_I2C=y CONFIG_FB_NVIDIA_BACKLIGHT=y CONFIG_FB_INTEL_I2C=y CONFIG_FB_MATROX_MILLENIUM=y CONFIG_FB_MATROX_MYSTIQUE=y CONFIG_FB_MATROX_G=y CONFIG_FB_MATROX_MULTIHEAD=y CONFIG_FB_RADEON_I2C=y CONFIG_FB_RADEON_BACKLIGHT=y CONFIG_FB_ATY128_BACKLIGHT=y CONFIG_FB_ATY_CT=y CONFIG_FB_ATY_GENERIC_LCD=y CONFIG_FB_ATY_GX=y CONFIG_FB_ATY_BACKLIGHT=y CONFIG_FB_SAVAGE_I2C=y CONFIG_FB_SIS_300=y CONFIG_FB_SIS_315=y CONFIG_FB_GEODE=y b...@bob:/boot$ -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

How to selectively automount USB disks under GNOME?
Hello, me and USB again. I normally use usbmount to automount USB disks. To download pictures from my digital camera's card, I've written a hook script which checks for certain things (the existence of a "DCIM" folder, specifically), and if these are found, automatically downoads all images from the card and sorts them into the appropriate folders. This works fine when I use my favorite environment (console and fvwm), but when my wife uses the Gnome desktop, some other automount mechanism seems to override usbmount. I don't want to tuen off the Gnome automount machanism altogether, because of course USB sticks and other stuff should still be mounted as before. It's just that volumes which have certain properties should be processed specifically. Is this possible?

How to change console font?
Hello folks, since many kernels ago I've used VGA console fonts that have been more pleasant than the standard 80x25 screen (mode 775). However, since my recent upgrade to lenny, this often doesn't work any more. Sometimes I get the font I want, sometimes I get the 80x25 one, and sometimes I get asked which mode I want (as if I had given the "vga=ask" boot option). I don't know why this is so erratic, but my system seems to slowly settle for the "ask" way of doing things. Well, I now want this to stop. A font that I really like is the one Knoppix uses. I think it is a framebuffer mode (it has the pengiun logo, too, which I don't care much for). How can I activate a mode like this? I'm running the 2.6.26-1-686 kernel from lenny. Speaking of kernel: I noticed that in lenny there aren't any -k7 kernels any more (or rather, the package is "for transition only"). Does this mean that the 686 and k7 branches have been merged?
