> I'm interested in the automounter. I would be very nice to have my jumpdrive mount when I plug it in. Also, if anybody knows udev... I managed to just set up automounting on my gentoo box, via some udev rules, HAL, D-BUS and a neat little app called ivman. Ivman will detect when new devices are plugged in and create a new entry in fstab if there isn't already an acceptable one (it'll remove the entry when the device is not connected); it can also be set up to do some more interesting things, such as integration to say start up your burning program when a blank CD-R is put in, etc. Using some udev rules (this is a great reference http://www.reactivated.net/writing_udev_rules.html) isn't *that* hard. You can use the program udevinfo to find out information about your plugged in devices to write appropriate rules. For example, I have a rule to link the device to a node /dev/nikon for my nikon camera, whenever it is plugged in. Then, I have an entry in /etc/fstab to mount /dev/nikon at /media/nikon, and lvman takes care of that (detects when that node is linked, reads fstab and mounts appropriately - if I didn't have that entry in fstab it would create one to mount at like /media/usbdevice01 or something). It even (usually) unmounts the device without issue (figuring out why it doesn't always). Since the serial number for each device is specific, my rule just uses that, so it looks like: SYSFS{serial}="SERIAL OF MY NIKON", NAME="%k", SYMLINK="nikon" to link node /dev/nikon to my camera. I had to use mknod to create that node initially (just a simply character device, I believe, can't remember the major/minor numbers off the top of my head). Of course you need to make sure you have hotplug installed and enabled in your kernel, as well as usb_storage and the SCSI modules (needed for the usb-storage module to work, according to kernel documentation). -- Carlton C.

I know udev takes care of mounting your specific jumpdrive to /mnt/myJumpDrive, but doesn't the automounter automatically mount cds and other stuff? Or am I in left field?

Eric> I'm interested in the automounter. I would be very nice to have Eric> my jumpdrive mount when I plug it in. Also, if anybody knows Eric> udev... I've got udev tamed enough to put devices where I want them when I plug them in. Automounting isn't there quite yet, though my wife would like it. Heck, I just finally switched my desktop to gnome as a full time test. We'll see how it goes with a real desktop she can find things on. Not that I really need icons on my desktop. Anyway, in terms of writing Udev rules, the key is to parsing the output of the 'udevinfo' tool. It's a pain to use in alot of ways, but not impossible. Basically, do: lsusb plug in device cat /proc/partitions ( for usb-storage) lsusb see what changed. udevinfo -q all -p /sys/... -a | less The trick is figuring out which device to look through in /sys/. For Compact Flash adapters and such, I would just cat /proc/partitions and see what changed and do: udevinfo -q all -p /sys/block/sde -a | less and then look through things. Thne I went and edited the file: /etc/udev/rules.d/10_local.rules and added lines like this: # Cruzer USB (Thin, 512mb) BUS="usb", SYSFS{product}=="Cruzer Mini", SYSFS{serial}=="2004351271076612cf2d" , KERNEL="sd?1", NAME="%k", SYMLINK="cruzer-thin" # Cruzer USB (Thick, 256Mb) BUS="usb", SYSFS{product}=="Cruzer Mini ", SYSFS{serial}=="000062894" , KERNEL="sd?1", NAME="%k", SYMLINK="cruzer-thick" # Compact Flash Reader BUS="usb", SYSFS{idProduct}=="0700",SYSFS{idVendor}=="05e3", NAME{all_partitions}="cf" # Epson Printer R300 Compact Flash Reader BUS="scsi",SYSFS{model}=="Stylus Storage ",SYSFS{vendor}=="EPSON " , NAME{all_partitions}="epson_cf" The key was the serial number(s) for stuff, and the idProduct & idVendor (from lsusb) in terms of how to mount stuff like the Compact flash reader which doesn't have a serial number, nor did the CF cards. Hopefully this will help. BTW, I'm on a debian system. John

Re: [Wlug] Disabling eth0 upon bootup

by Adam Keck

Hello Mike, https://wiki.ubuntu.com/WiFiHowto provides a large amount of doc on doing wifi the Unbuntu way (TM), including disabling eth0. If that does not help, you ought to be able to enable and disable interfaces in the configuration file /etc/networking/interfaces (man interfaces for syntax). On straight Debian that file is parsed by the ifup program at boot time. -Adam On Oct 21, 2005, at 12:31 AM, Cretella, Michael A wrote: > Hey all- > > > I'm running ubuntu 5.10, and trying to understand how the linux bootup > process works..

Disabling eth0 upon bootup

by Cretella, Michael A

Hey all- I'm running ubuntu 5.10, and trying to understand how the linux bootup process works.. Right now upon bootup I'd like to change two things: Not ifup eth0 Configure wpa_supplicant to boot up with the right parameters in order to configure itself to the wireless network here. I think I figured out how to get the wpa_supplicant to work-- I just edited /etc/init.d/wpasupplicant and changed $OPTIONS to the arguments I need in order for it to work. For disabling eth0 on bootup, I could modify /etc/init.d/networking and change the command "ifup -a" to "ifup wlan0" to just boot up my wlan0 on bootup, but I feel there might be an easier way to do this... Hope you can help! -Mike --------------------------- Michael A Cretella Worcester Polytechnic Institute Electrical Computer Engineering '07 cretella(a)wpi.edu (203)610-3618
