README for udevil v0.4.0+ For updates and instructions visit: http://ignorantguru.github.com/udevil/ http://ignorantguru.github.com/udevil/news.html CONTENTS DESCRIPTION PACKAGES INSTALLER BUILD BUILD NEXT CREATE DEB PACKAGE POST INSTALL Kernel Polling Networks and Files NTFS-3G Set SUID systemd Service ENABLE KERNEL POLLING UNINSTALL TRANSLATE LICENSE DESCRIPTION Mounts and unmounts removable devices and networks without a password (set suid), shows device info, monitors device changes. Emulates mount's and udisks's command line usage and udisks v1's output. Includes the devmon automounting daemon. Run 'udevil --help' for usage. See /etc/udevil/udevil.conf for config. http://ignorantguru.github.com/udevil/udevil--help.html http://ignorantguru.github.com/udevil/udevil.conf.txt PACKAGES Find or add packages, forum threads, and other info for your distro: https://github.com/IgnorantGuru/spacefm/wiki/Distros For other distros: See INSTALLER below NOTE: See POST INSTALL section below for post-installation steps. INSTALLER A self-extracting installer is available (udevil-x.x.x-installer.sh): https://github.com/IgnorantGuru/udevil/tree/master/packages (To save a file, click on its filename and click 'View Raw') The installer requires the build dependencies listed below in BUILD. If any dependencies are missing, examine the error, install missing packages, and try again. The installer MUST be run in a terminal. It automatically builds and installs. Run it like this: bash udevil-x.x.x-installer.sh or to see options: bash udevil-x.x.x-installer.sh --help To reinstall or upgrade, just run the latest installer again. NOTE: See POST INSTALL section below for post-installation steps. BUILD 1) Install required build dependencies (below are Debian package names - packages names on your distro may vary but should be similar): libglib2.0-0 libglib2.0-dev libudev0 (>=143) libudev-dev autotools-dev build-essential fakeroot intltool pkg-config Also recommended for network support: cifs-utils curlftpfs sshfs Also recommended if using devmon: eject spacefm|zenity configure will report anything missing when you run it as shown below. 2) Use these commands to download the udevil tarball and build: # Download & Extract mkdir /tmp/udevil-build && cd /tmp/udevil-build wget -O udevil.tar.gz https://github.com/IgnorantGuru/udevil/tarball/master tar xzf udevil.tar.gz cd IgnorantGuru-udevil-* # Build & Install ./configure make sudo make install # Remove Temporary Files cd / && rm -rf /tmp/udevil-build NOTES: * If configure reports missing dependencies, install them and run configure again before proceeding to make. * By default, systemd configuration files for devmon are installed to: /etc/conf.d/devmon /usr/lib/systemd/system/devmon@.service To skip installation of these files, use configure option --disable-systemd In either case, systemd is NOT required. * See POST INSTALL section below for post-installation steps. BUILD NEXT The git 'next' branch of udevil is a work in progress which eventually becomes the next release version. To build from this branch, install the required build dependencies listed above in BUILD, then: # Download & Extract mkdir /tmp/udevil-next && cd /tmp/udevil-next wget -O udevil-next.tar.gz https://github.com/IgnorantGuru/udevil/tarball/next tar xzf udevil-next.tar.gz cd IgnorantGuru-udevil-* # Build, & Install ./configure make sudo make install # Remove Temporary Files cd / && rm -rf /tmp/udevil-next CREATE DEB PACKAGE To build a deb file of udevil on your Debian-based distro: 1) Install build dependencies (see BUILD section above) plus 'debhelper'. 2) Use these commands to download and extract the udevil tarball (be sure to USE A TMP BUILD PATH THAT DOES NOT CONTAIN SPACES): mkdir /tmp/udevil-build && cd /tmp/udevil-build # no spaces in path # Note: you can change "master" to "next" if you want the next branch: wget -O udevil.tar.gz https://github.com/IgnorantGuru/udevil/tarball/master tar xzf udevil.tar.gz cd IgnorantGuru-udevil-* 3) Move the distros/debian directory into the source directory: mv distros/debian . 4) Build package: (the package files will appear in the parent directory) dpkg-buildpackage -b -uc cd .. && rm -rf IgnorantGuru-udevil-* udevil.tar.gz 5) To install the package you built: dpkg -i udevil*.deb POST INSTALL Kernel Polling -------------- You may need to enable kernel polling for device media to be detected by udevil. See ENABLE KERNEL POLLING section below. Networks and Files ------------------ By default, /etc/udevil/udevil.conf is set to allow only local fileystems and ISO files to be mounted, with mounting of networks disallowed. To allow networks and files to be mounted, in /etc/udevil/udevil.conf set: allowed_types = $KNOWN_FILESYSTEMS, file, cifs, nfs, curlftpfs, sshfs, davfs You may also need to install curlftpfs or ftpfs (ftp://), cifs or smbfs (smb://), sshfs (ssh://), and davfs2 (http://). NTFS-3G ------- If local ntfs filesystems aren't mounted writable, you may need to configure your system to mount ntfs with ntfs-3g (on some distros this is already done). For example: sudo ln -s /sbin/mount.ntfs-3g /sbin/mount.ntfs # OR if mount.ntfs-3g is located in /usr/bin: sudo ln -s /usr/bin/mount.ntfs-3g /usr/bin/mount.ntfs Set SUID -------- After installing udevil, /usr/bin/udevil should have the suid bit already set. If not, set it like this: sudo chown root:root /usr/bin/udevil sudo chmod u+s,go-s,ugo+x /usr/bin/udevil ls -l /usr/bin/udevil -rwsr-xr-x 1 root root 226625 May 22 08:13 /usr/bin/udevil OR, to restrict execution of udevil to the 'plugdev' group only: sudo chown root:plugdev /usr/bin/udevil sudo chmod u+s,go-s,o-x /usr/bin/udevil ls -l /usr/bin/udevil -rwsr-xr-- 1 root plugdev 226625 May 22 08:13 /usr/bin/udevil OR, if you don't want to use udevil for mounting, you can unset suid: sudo chown root:root /usr/bin/udevil sudo chmod ugo-s,ugo+x /usr/bin/udevil ls -l /usr/bin/udevil -rwxr-xr-x 1 root root 226625 May 22 08:13 /usr/bin/udevil You can also limit users and groups by editing /etc/udevil/udevil.conf systemd Service --------------- To start devmon as a systemd service: systemctl start devmon@ ENABLE KERNEL POLLING You may need to enable kernel polling for device media to be detected by udevil. For example, if you insert a CD and udevil's monitor command doesn't report a change to the device, or udevil doesn't see a filesystem on the device, this is a symptom that kernel polling is not enabled. Kernel polling is a new feature of the Linux kernel and udev, so most distros don't yet have it enabled. Even if you are using udisks, enabling kernel polling is recommended to eliminate the need for udisks to do userspace polling. Kernel polling also corrects a common issue where the eject button on a drive won't respond with the newer udev. To use kernel polling, your Linux kernel may need to be 2.6.38 or newer, and udev may need to be version 173 or newer. TO DETERMINE IF KERNEL POLLING IS ENABLED, run these commands: cat /sys/module/block/parameters/events_dfl_poll_msecs cat /sys/block/sr0/events_poll_msecs If you get 0 or -1 from those commands, then it's probably disabled. TO ENABLE KERNEL POLLING PERMANENTLY (survives a reboot), add this command to your /etc/rc.local file (anywhere before the 'exit' line in that file): echo 2000 > /sys/module/block/parameters/events_dfl_poll_msecs Any number between 2000 and 5000 (milliseconds) should be reasonable - the higher 5000 means poll every 5 seconds, which is less overhead but a little slower. OR you can pass this option to the kernel boot command line in grub: block.events_dfl_poll_msecs=2000 TO ENABLE KERNEL POLLING TEMPORARILY, enable common polling for the block module: sudo bash -c 'echo 2000 > /sys/module/block/parameters/events_dfl_poll_msecs' OR you can enable polling just for a single device like this (/dev/sr0 in this example): sudo bash -c 'echo 2000 > /sys/block/sr0/events_poll_msecs' The change should be immediate - media will be detected and the eject button on the drive should work normally again. However, the above changes will be lost when you reboot.

Otherwise, extract the tarball and enter the directory containing configure: # first run configure with your original options if needed: ./configure sudo make uninstall # Note: /etc/udevil/ is not automatically removed TRANSLATE To help translate udevil please visit: https://github.com/IgnorantGuru/spacefm/wiki/Translate At Transifex: https://www.transifex.com/projects/p/udevil/ Just sign up for a free Transifex account.
