Re: automounting
by Carlton C. Stedman II 21 Oct '05

> 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.

November talk topics
by Jeff Moyer 21 Oct '05

21 Oct '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I just recently got back from Germany, where I gave two talks at this year's Linux Kongress. One talk focuses on the state of the automounter, and the other discusses the netpoll API. You can find abstracts at the Linux Kongress website: http://www.linux-kongress.org/2005/abstracts.html If the group is interested in either of these, I'd be more than happy to present. I could also give a quick run-down of what the conference was like, who to go out drinking with, etc. Slides for these talks are available on my people page: http://people.redhat.com/jmoyer/index.html#presentations If there's no interest in these topics, it won't hurt my feelings. Honest. ;) - -Jeff -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) Comment: Processed by Mailcrypt 3.5.8 <http://mailcrypt.sourceforge.net/> iD8DBQFDWQN3H/inyh944bQRAvDWAKCjgzHar2HHSf2/hwlRcWMLp4rKmACfWpoR X0VUV6CwwRi6Hnd+L6jVMio= =D3Z8 -----END PGP SIGNATURE-----

Disabling eth0 upon bootup
by Cretella, Michael A 21 Oct '05

21 Oct '05

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

DELL 720 printer shared on SAMBA??
by Ken Jones 15 Oct '05

15 Oct '05

I've unsuccessfully googled this problem. Maybe you folks know a solution. My wife received a freebie DEL 720 printer. It is really a relabeled Lexmark z600 type. By downloading a driver from Lexmark, I got the printer running on my FEDORA 4 machine. I want to share this printer using SAMBA. After installing the same driver on my FEDORA 3 machine its CUPS sees the remote printer and "installs" it. When I ask to print a test page it announces that it had sent the page. Nothing happens on the FEDORA 3 machine to which the printer is attached. It's CUPS says that nothing is in the printer's queue. Any ideas? Ken Jones

RE: [Wlug] deleting a file named "--exclude"

If the Unix shell doesn't like it then try something else... You could try something like: bash-2.05b$ python >>>import os >>>os.unlink('--exclude') >>><Control-Z (just to exit python)> Assuming you have python installed. I think this should be installed by default on most Linux systems. -----Original Message----- From: wlug-bounces(a)mail.wlug.org on behalf of dulsi(a)identicalsoftware.com Sent: Fri 10/14/2005 11:51 AM To: wlug(a)mail.wlug.org Subject: Re: [Wlug] deleting a file named "--exclude" No. Unix shells expands everything on the command line before running the program. So "rm *exclude" and "rm ??exclude" expand to "rm --exclude". The program cannot tell that the "--exclude" was expanded from wildcard values.

Hi all, Anyone have a Ilssan ISF 120SI compatible Power supply they'd be willing to sell me cheap? This is for an eMachines box that died in a lightning storm. It's for a couple with limited means and I just don't have any spares around the house at all. Specs for what I'm looking for: Input: 100-120VAC 3A Ouput: +3.3V +5V +12V -12V +%VSB 6A 14A 2A 0.3A 0.72A 120W It's a small power supply with a built in Fan that sticks out. More info (web pages for compatible ones) available on request. Thanks, John

Seeking someone to install SuSE Linux
by Andy Stewart 10 Oct '05

10 Oct '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, Mel Korman came to his first WLUG meeting this past Wednesday asking for our help to get Linux installed on his laptop. Those of us who attended the meeting thought that his RedHat 9.0 might be too old for its installer to comprehend the external USB hard drive on which he had hoped to copy Linux, so I gave Mel the SuSE 9.3 Pro CDs which I had at the time, in the hope that he'd have a better time with the installation. Mel gave it a try at home but things are not working. Mel has offered to pay someone who would be willing to get Linux installed on his Thinkpad laptop (where Windows is also installed). If you are interested in helping Mel, please contact him directly at finkor(a)verizon.net. Thanks!

Meeting minutes from earlier this week
by Andy Stewart 07 Oct '05

07 Oct '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, We had our meeting in one of the rooms right off of the Morgan Hall dining area. I think there were 7 or 8 of us, with two newcomers (welcome!). The discussion started with GRUB and some of its more interesting features vs. LILO, such as command line editing and adding graphics to the background. I had made a GRUB bootable CD prior to the meeting. GRUB has a large number of features, and we touched on only a few. After that, we somehow ended up on the topic of VNC: http://www.realvnc.com http://www.tightvnc.com <-- There was also interest in the "suspend to disk" feature of my laptop, which actually worked in a live demo. One person asked if it was possible to do this on a desktop machine (I don't think so....). In addition, Mel K. (newcomer) brought his laptop, onto which he wanted to install RedHat 9.0, which was having trouble recognizing his external USB hard drive. I gave Mel my SuSE 9.3 pro CDs and asked him to give that a try. Mel said that he'd keep us apprised of his progress. Pizza / soda followed at the Tech Pizza restaurant where we've gone after the last several meetings. Mel mentioned that he has interest in VistA (open source medical software). Try http://www.vistasoftware.org and google turns up other seemingly related links. Later, Andy - -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA, USA http://www.wlug.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFDRx4CHl0iXDssISsRAgHDAJ9ZQ4B0Morwv7EcxvAicO9fCxl2LgCdFxFg 5z9ZHpXjfJMuedYXi0ySZMI= =fVQp -----END PGP SIGNATURE-----
