udev device removal not removing file

by Karl Hiramoto

I have some USB serial port devices that show up in /dev/tts/USB0 and /dev/tts/USB1 for example.. I have 4 gentoo boxes, and on one of them when I remove the device file does not disappear, on the other boxes the file disappear. What could be causing this? Adding a device is no problem, only the removal does not remove the device file /dev/tts/USB1 for example dmesg shows the device addition and removal just fine. I copied /etc/udev/* from a working machine where removal happens fine the one with problems with device removal and there was no change. They are all running the same kernel, hotplugg, baselayout.. This is an issue for me as i have a program of my own that looks for /dev/tts/USB* Any ideas out there? Thanks.

Hello Aramico, Are you trying to connect to a VPN server or are you trying to provide VPN services to others? -Adam On Jun 15, 2005, at 8:07 AM, Aramico wrote: > Dear Friends, > > > Can you all please suggest me kind of VPN application based on Linux > (especially RedHat 7.3 compatibility) ? > > > Thanks, > > Aramico > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug

Need Homes: 2U+,custom cases/psupp/fans

by Doug Mildram

Yet another Westboro,MA giveaway: (Anyone teaching EE or Hobbies909?) Free and basically new: empty/nonstandard cases w/powersupp+fans. A dead project has left homeless ~15 cases, 19" wide, 24" deep, (19" wide == standard 18.5" distance between frontpanel mounting holes) 4.5" high == including .5" high rubber feet. (2U == 3.5", these are taller), semi-empty inside (a 13"x14"x3.5" area inside plus a 6"x8"x3.5" along psupply) 19" rackmountable , BUT, ***** NOT ***** set up for PC-based motherboard: does NOT include disk/floppy/usb brackets or any of THAT pc-ready stuff. http://webpages.charter.net/mquinty/case_top.JPG Each case has a 400W standard 12v/5v power supply, and (4) 3.5" fans already mounted (side exhaust) inside; a removable suitcase-strap-panel on the front as shown; (see picture case_front.JPG URL below..but it hides the switches below) also on front panel: 1 power switch; 2 LEDs, "Fan Fail" and "Power". http://webpages.charter.net/mquinty/case_front.JPG Even MORE Gory detail: Each case has a custom (now useless) NONstandard screw-post arrangement which you'd need to re-do (re-drill new holes as needed, may need shorter posts). So it's good if you have something REALLY CUSTOM you want mounted+powered. If you ask for just the power supplies, you're missing my mantra: these babies (CASES) need an inventive home or homes. -- doug mildram

Reminder: WLUG Meeting, Wed June 15, 7:00 PM

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, This is a reminder about the WLUG meeting to be held on Wednesday, June 15, 2005 at 7:00 PM in the Access Grid room on the WPI Campus in Worcester, MA USA. This meeting is open to anyone who is interested in Linux. Tim Keller will be our guest speaker, and he'll be talking about Logical Volume Management (LVM). More details can be found on the WLUG home page. I will have two books for the no cost raffle: Succeeding with Open Source by Bernard Golden Published by Addison-Wesley 2005 PHP5 Power Programming by Gutmans, Bakken, and Rethans Published by Prentice Hall 2005 The raffle winner is requested to write a review of the book and to post it somewhere on the Internet, and to copy the publisher. We had discussed the possibility of a summer barbecue in lieu of the July meeting. I think someone said we could have the party at their place, but I can't remember who said that. If this person was serious, please contact me via email and we can work out the particulars. It'll be a nice way to celebrate WLUG's 8th anniversary (we started July 1997)! After the meeting, we'll go out for pizza/soda at the Tech Pizza restaurant on Highland Street. Its a small place, but the 8-10 of us that go seem to be having a good time, and we've never had to wait for a table. :-) It may be hot in there this time of year...we'll have to scope it out. See you on Wednesday!

My dual PIII 450MHz system is now a MythTV backend, and it seems quite happy in that role. :-) 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 iD8DBQFCq6mgHl0iXDssISsRAu6TAJ9EsNQVMwogKOSmUB1weKE2XU83pgCfZGSI 9n5fJ5mD4VwfZD2LxGcLg1E= =6fO7 -----END PGP SIGNATURE-----
