Debian :: Run Script From Udev?
Aug 30, 2010
I'm trying to run a script when a sd card is inserted into the drive. my udev rules are as follows:
BUS=="usb", KERNEL=="sd*", SYSFS{serial}=="058F63356336", NAME="sdcard", RUN+="/bin/mount /dev/sdcard"
BUS=="usb", KERNEL=="sd*", SYSFS{serial}=="058F63356336", OPTIONS+="last_rule", RUN+="/home/user/test"
The first line works, naming the device as "sdcard" and mounting it in the correct location. The second line should run a simple script to write a file with some text in it. If I run the script it works so I'm assuming it's not being done by udev but I done know why.

Is it possible to run kde in Wheezy without udev? I am asking this because the modesetting failure is manifested as soon as udev tries to populate the /dev directory.

I was trying to install recent updates, but apt-get couldn't do this. Here's the output I got:
Code: Select all(Reading database ... 187979 files and directories currently installed.)

Now I can't continue upgrading because every time it tries to finish the previous update and fails to process udev.
I don't know if it's relevant, but while upgrading udev for the first time, my laptop switched to tty1 on its own. When I switched it back to graphic subsystem, it still was in process of upgrading udev or systemd and after all failed to finish.

I have a problem copying my udev rules from other distro to another pc running debian. My box is running debian without any DE and I want my USB disks to be automounted based on the label; I believe udev is the nicest way to do this task.
Anyways : my rules are (copied from archlinux wiki btw)
cat /etc/udev/rules.d/92-my-media-automount.rules
# vim:enc=utf-8:nu:ai:si:et:ts=4:sw=4:ft=udevrules:
# /etc/udev/rules.d/92-my-media-automount.rules
# Only work on sd*
KERNEL!="sd[a-z]*", GOTO="my_media_automount_end"
ACTION=="add", PROGRAM!="/sbin/blkid %N", GOTO="my_media_automount_end" .....
I notice the directory is made successfully up inserting the usb HD, but the mount doesn't succeed. If I manually execute above command, the mount goes ok.

I am using Debian Squeeze on my laptop an now I want to write udev rules. I bought an USB enclosure for my old Desktop HDD drive (Debian lenny ). But when I plug it in only the first primary partition gets mounted so I can not copy the data from my old desktop to the laptop. the output of mount shows that the following disk was mounted/dev/sdb1 on /media/disk type ext3 (rw,nosuid,nodev,uhelper=hal)
I can cd into /media/disk/etc and cat fstab shows the following:
# /etc/fstab: static file system information.

I have SSD drives without SCT support, because of this I want to tune /sys/block/device-name/device/timeout in order to force mdadm put these drives offline. So, I can see my drive like this:
/dev/disk/by-id/ata-OCZ-SABER1000_A22MJ061512000074.
Where can I tune /sys/block/device-name/device/timeout from 30 to 7 sec only for these drive? I don't want to use rc.local.
Can I create right udev rules for it in /etc/udev/rules.d?
I want to avoid any conflict with /lib/udev/rules.d.
Code: Select all# udevadm monitor --environment --udev
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
UDEV [9302.549485] add /devices/pci0000:00/0000:00:01.2/0000:03:00.0/host0/target0:0:0 (scsi)

I'm trying to allow non-root account to use avrdude to program mucrocontrollers. There are many articles online about how to do that, but it seems not to work for me. Every time i try to execute avrdude it says "permission denied". Here's "$ udevadm info --name=/dev/bus/usb/002/011 --attribute-walk" says looking at device '/devices/pci0000:00/0000:00:1d.1/usb2/2-1':
KERNEL=="2-1"
SUBSYSTEM=="usb"
DRIVER=="usb"
ATTR{configuration}==""
[code]....
However, after restarting udev, replugging the device, even rebooting the computer I still get "permission denied". The Vendor and Product match, so what's the problem?

I've just installed 'Testing' on a VMware server and after I completed the install with no problems, the system booted into the kernel and I noticed the following start up process error:
Code:
startpar: service(s) returned failure: udev...failure!!!
I have not seen this before and am not sure if it's related to the fact that this is a virtual machine and not a physical server or something else. Here is a Screenshot.

I should create a sqeeze image and install it on other computers.Udev should detect network card (NIC) module and load it automatically at startup.How I understand /lib/udev/rules.d/75-persistent-net-generator.rules runs when udev starts, then writes to /etc/udev/rules.d/70-persistent-net.rules.The problem is, udev searches for this NIC on other hardware and the network cannot start.I can solve this problem easily using a startup script to delete /etc/udev/rules.d/70-persistent-net.rules file.

im using Debian (lenny) with 2.6.26 kernel, I'm trying to write udev rules in order to automount my usb pendrive, so I added this rules in udev:
SUBSYSTEM=="block", SUBSYSTEMS=="scsi",ATTRS{vendor}=="OTi ",
ATTRS{model}=="Flash Disk ", NAME="penna128M",RUN="/usr/bin/
pmount /dev/penna128M"
I use pmount to install the device as normal user If i connect my device to the usb port I don't see nothing in /media/penna128M, BUT giving at the prompt cat /etc/mtab the last line is:
/dev/penna128M /media/penna128M vfat rw,noexec,nosuid,nodev 0 0
The line in fstab about this pendrive is:
/dev/penna128M /media/penna128Mvfatdefaults,user,owner,auto00

I have just bought a DVB-T usb dongle to watch some TV. The software I'm using is vdr, which has to be started through the /etc/init.d/vdr service. I have created a udev script that executes the service on device insertion. It works nicely, however now when I boot up the computer it takes ages to get to desktop. I believe it is because of the WAIT_FOR part. But without this part, the service starts too soon because the usb dongle has been inserted but the firmware has not finished loading. Can someone point out an alternative way to do it? The script is here [URL].

Primary symptom: /proc/self/fd is there and normally populated, however /dev/fd is not. Process substitution therefore fails, because bash wants to create files under /dev/fd./dev/.static/ and /dev/.udev are populated. aptitude udev shows that the Debian package is installed, even though udev cannot be supported on this Xen vps (and, I believe, isn't supported by default until later stable versions of the Linux kernel).
I can solve the immediate problem by symlinking from proc/self/fd to /dev/fd, and putting the appropriate script in init.d. But are there any risks arising from Debian being misinformed about what my vps can do? And if so, what should I do about it?

I am using a 3rd party kernel driver that does not support udev properly. When I was using wheezy I placed the required device files in /lib/udev/devices.
The udev in jessie does not appear to support this. Is there any way to have udev create these device files or will I have to create then using a script at boot-up?

I have a trayless SATA hotswap bay that is really terrific for quickly attaching and removing SATA hard drives. I'm trying to write a udev rule to create a symbolic link to the device node for the drive that is attached through the hotswap bay (/dev/bay -> /dev/sdX). This eliminates any ambiguity when performing destructive tasks (fdisk, etc). I'm running squeeze amd64. I've read through several tutorials and have it working somewhat. Here's the output of udevadm info for a drive attached via the hotswap bay.
looking at device '/devices/pci0000:00/0000:00:11.0/host7/target7:0:0/7:0:0:0/block/sdb':
KERNEL=="sdb"
SUBSYSTEM=="block"
DRIVER==""
ATTR{range}=="16"
ATTR{ext_range}=="256"
ATTR{removable}=="0"
ATTR{ro}=="0"
ATTR{size}=="156301488"
ATTR{alignment_offset}=="0"
ATTR{capability}=="52" ....
Here is my udev rule
DEVPATH=="/devices/pci0000:00/0000:00:11.0/host7/*", SUBSYSTEM=="block", SYMLINK+="bay%n"
This produces the desired behavior and gives me an fdisk-able device node. The problem I am having is that the "host" component of the DEVPATH varies from bootup to bootup. I'm just using on onboard SATA, host2-7, specifically host7. There is also onboard PATA, host0-1. It seems to just be random which "host"s are assigned to which controller. For example, the next time I boot the system, the onboard SATA will be host0-5 and the onboard PATA will be host6-7. In this simple case, I could just write 2 rules, one for each possibility and it would still be correct because of the different PCI addresses of the two controllers. But on systems with more SCSI (uh... libata, actually) controllers, a "host" file can point to different physical ports between bootstraps. This would be bad. Does anyone know of a way to write a rule to tie a device node to a specific physical SATA port on the motherboard/hba?

Recently I have noticed that at times my keyboard will act as though shift is pressed. That is, letters are capitalized and when i press a key, its shift equivalent is shown. I actually first noticed this behaviour on fedora 12 beta (i believe fedora has been using udev/DeviceKit since F11). At the time of F12 beta I was not aware of fedora using udev. Where can I find a comprehensive guide to setup udev? Or if it all fails, how to re-enable settings in xorg?
Here is what cat /var/log/Xorg.0.log | grep -A 5 -B 5 evdev shows
(II) Initializing extension GLX
record: RECORD extension enabled at configure time.
record: This extension is known to be broken, disabling extension now..

I have a Logitech marble mouse (trackball, https://help.ubuntu.com/community/Lo...arblemouse_USB) which works great under HAL in Ubuntu 9.10. For me it is simply not as usable without HAL, because it doesn't appear to be possible to have a button assigned to more than one thing.
With HAL, you can click the back button on the trackball to go 'back', e.g. in Firefox, Nautilus, or you can hold down the same button to use vertical and horizontal scrolling with the ball (as opposed to the normal mouse movement when the button is not held down). You can also get a 'middle mouse' press by clicking both left and right buttons at once. restore HAL to the boot process so I can regain this functionality? Or is it not possible? It would be just as good if I could get this same functionality without HAL, but I don't see how that can be done using xorg.conf.

I have two touch screen monitors tha tI'm configuring for a dual-head display.That is working.For the touch screens it's a bit more complicated, each touch screen requires that I apply a specific config file for each individual TS (touch screen). Each config file is unique to it display. for that I'm using xinput to apply those configuration.My problem here is that the TSs are the same model and show up under udev and xinput under the same the same name minus the different hardware IDs whish is the only way that I can currently distiguish them.So far I've experimented with tweaking the udev rules for a particular TS with no luck (more than likely because I might be doing it wrong).I ned to be able to tell the two appart when I apply the configurations in xinput so I can write a script that will do this automatically for me.

I am trying to list udev rules for devices ( similar to lshal ). lsdev is not listing what i want. trying to write udev rule for ALSP touchpad. Upon reading the guide at this site, I am not seeing the ../10_local.rules which is indicated as the correct pat to save user defined udev rules.
Code:
ls /etc/udev/rules.d
Would I be correct in assuming that I save my rule as
Code:
/etc/udev/rules.d/mouse.rule
Device ID:I am confused also as to which device is actually being used! running
Code:
cat /proc/bus/input/devices
i get a return with these entries:
Code:
I: Bus=0017 Vendor=0001 Product=0001 Version=0100
N: Name="Macintosh mouse button emulation"
P: Phys=
[code]....
I have followed howtos as listed here, here, and here. Am I not pointing my mouse.rules to the correct location? Maybe my issue is that I followed howtos from varied sources.the mouse.rules i put in /etc/udev/rules.d/mouse.rules had no effect.
