General :: Script In Udev Rule Doesn't Run?
Jan 13, 2010I'm running Ubuntu 9.10 (Karmic Koala) on a laptop and would like NumLock to automatically toggle depending on whether my USB keyboard is plugged in (numlock on) or unplugged (numlock off).
To accomplish this, I first installed the "numlockx" package. numlockx on and numlockx off works fine.
To hook into the device system, I thought I'd use udev. I have read "Writing udev rules", but I'm having trouble getting the udev rule to work.
First, here's an example of the dmesg output:
[20906.985102] usb 3-2: new low speed USB device using uhci_hcd and address 6
[20907.166403] usb 3-2: configuration #1 chosen from 1 choice

Ubuntu Networking :: Udev Rule Is Ignored For Eth Devices?
Jun 3, 2010I'm trying to set my network interfaces so that they don't get random every boot.(eg assign eth0 to a network interface with a given MAC addr, and eth1 to the other one)I trew in a udev rule (in fact just modified the rules that was automatically generated and set the ethX in it) but the system ignores my udev rule.What am I missing ?Here is all the info :

Software :: UDEV Rule Not Running A Command?
Aug 1, 2010I have a UDEV rule below that maps a symlink from a specific usb device and 'Should' run a command.
Code:
BUS=="usb",SYSFS{serial}=="1111111111111111111111111111",SYMLINK+="myusbstick_%n",RUN+="/usr/local/bin/my_command"
The symlink part is fine but it does not appear to run the command when I plug the device in. I can run the command "/usr/local/bin/my_command" from the shell fine.
Code:
mount /dev/myusbstick_1 /media/TMPUSB && cryptsetup luksOpen /dev/md5 md5_crypt --key-file=/media/TMPUSB/key && vgscan && vgchange -ay && mount -a && umount /media/TMPUSB
What am I missing. I have tried +x in owner,group and other.By the way what does UDEV run as, I assumned +x on ROOT as that is the owner should be enough.
Ubuntu :: Udev Triggers Add-rule Multiple Times?

Slackware :: Udev Rule Not Starting Gpsd During Boot?
May 29, 2011I'm trying to configure gpsd 2.96 to start automatically from udev rule on a Slack 13.37 box.1. I've compiled and installed gpsd from sources and made sure it starts manually.2. I've copied the /lib/udev/gpsd.hotplug and /lib/udev/gpsd.hotplug.wrapper scripts in their places from the source tree and made them executable.3. I've copied the gpsd.rules file from sources into /etc/udev/rules.d4. I renamed it 99-persistent-gpsd.rules to run late in the bootup process.5. I've copied the /etc/default/gpsd file from sources and made sure it has the right settings inside.
Now, for the results. If I plug the gps usb dongle in while the system runs, it starts gpsd if it is not started, and it connects to it just as it should. But if I start the system with the dongle in, gpsd doesn't get started during boot. I can't find any relevant message in /var/log/syslog or /var/log/messages for boot time. There is stuff there from when I plug the dongle in while the system is running though. It's like udev ignores the rules for it at boot time.Is there something in the Slackware boot scripts that would prevent running those scriptssd.hotplug.wrapper which in turn runs /lib/udev/gpsd.hotplug which is a Python script)?Here is the contents of 99-persistent-gpsd.rules (ignore the comments referring to Debian, it was meant for a Debian box). My usb gps adapter is the first one - the Prolific chipset one:

Debian Configuration :: Creating Udev Rule For Specific SATA Port
Apr 19, 2011I 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?
Ubuntu :: Create An Udev Rule To Stop Card Reader From Being Initialized
Jan 24, 2010I have a netbook (MSI Wind U100 rebrand) that has one of those card readers built into the handrest. The thing is I've never used it once, and it keeps popping up in powertop as waking the cpu when it should just shut up and be quiet.Aside from breaking open the case and tearing it out, the immediate solution is to browse to /sys/bus/usb/devices/usb1/1-6/ and pipe 1 to the file remove. That disables it until system reboot or resume, at which point I have to do it all over again.
Code:
$ echo 1 | sudo tee /sys/bus/usb/devices/usb1/1-6/remove
Now I'd like to create an udev rule to make it not get initialized at all. A quick Google search found me this article on creating udev rules, and after toying about with the udevadm tool I managed to produce the attributes/properties of the device.
Code:
zorael@lethe:/sys/bus/usb/devices/usb1/1-6$ udevadm info -a -p $(pwd)
Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device.
looking at device '/bus/usb/devices/usb1/1-6':
KERNEL=="1-6"
SUBSYSTEM=="usb"
DRIVER=="usb"
ATTR{configuration}=="CARD READER

Ubuntu Security :: Set A Rule In Iptables, Does That Rule Also Apply To Ipv6, Or Just Ipv4?
Jul 16, 2010Question (and Google results aren't making this clear): Ubuntu has both iptables & ip6tables installed. 1. If I set a rule in iptables, does that rule also apply to ipv6, or just ipv4?
2. If "no" to above, then it would be prudent to *also* set ip6tables rules as well if I want to maintain an active firewall, correct?
3. Does ip6tables rules have the same syntax and behavior (more or less) to iptables rules - i.e. can I just copy my iptables rules & change "iptables" to "ip6tables"?
4. Any gotchas or issues that I should be aware of?
