I'm setting up udev to handle my external USB hard drive when it gets plugged in and removed (no mounting yet).
I'm running Arch Linux, and I have a udev rule which starts a service when a device is inserted.
Hi, While my udev rule works and triggers a bash script on USB insertion, media is not being mounted until +=RUN script ends. Rule file is the last one executed (z99.fooo.rules). Script is supposed to search for a specific file, if file found then runs a backup and beeps, then user can unplug usb device....
I have a device that is an contec cms-50f oximeter that connects to the computer using a usb cable.
When I do an lsusb command I can see it in the output
Bus 002 Device 004: ID 10c4:ea60 Cygnal Integrated Products, Inc.
udev is responsible for populating /dev. It adds and removes device nodes to /dev dynamically based on rules/configs/scripts under /lib/udev and /etc/udev/.
If I have a CDROM device node /dev/sr0 I can add a symlink /dev/cdrom by adding a rule like:
SUBSYSTEM=="block", KERNEL=="sr0", SYMLINK+="cdrom", GROUP="cdrom"
I understand how symlinks are created in udev.
I am trying to execute a shell script from udev rule, when a network interface is added, as follows:
SUBSYSTEM=="net", ACTION=="add", KERNEL=="eth*", PROGRAM="/usr/local/bin/changemac.sh", NAME="eth0"
The shell script is just changing the MAC address of eth1 using ifconfig command, as follows:
#!/bin/sh
/sbin/ifconfig eth0 hw ether 00:cc:dd:ee:ff:e1
echo "command return status $?" > /root/c
Udev-Discover is a sysfs browsing tool focused on helping udev users and developers.
I get this message (Could not find '' executable.) in terminal after using sudo apt-get since I installed and removed Krusader. I'm using Ubuntu 12.10 with Unity.
$ sudo apt-get remove gstm

I talkt with falconindy, because i got the same problem so there is the fix (workaround). I know falconindy don't like override permission by udev, but maybe OpenVZ Container need this. If i had time, maybe i will look deeper in it.Problem was upgrade from udev v182-4 to systemd-tools v184-2, because of removing the following line.
