Computer security today advances at an exceptional rate, as both its operational relevance and the tension between attackers and defenders continue to grow. New services, new systems, and new networking architectures continually add new dimensions to the field and subvert previously held assumptions. This symposium offers cutting-edge research on topics that range from Web-based detection through memory performance attacks. * The Security training program can help you learn the latest on topics such as: -- TCP/IP Weapons School -- Live Forensics Experts such as Richard Bejtlich, Dan Geer, Frank Adelstein, and Golden G. Richard will give you the information, techniques, tools, and strategies you need to practice effective security today--and tomorrow. * Don't miss the keynote address by Steven Levy, a senior editor and columnist at Newsweek, on "How the iPod Shuffled the World as We Know It." * The Invited Talks cover a number of timely topics, including: -- "Windows Vista Content Protection," by Peter Gutmann, University of Auckland, New Zealand -- "Exploiting Online Games," by Gary McGraw, Cigital -- And more... * The 23 refereed papers present the best new research in a variety of subject areas, including privacy, cellular network security, and authentication. * Join colleagues with similar interests for thought-provoking discussions at the evening Birds-of-a-Feather sessions. * Share a provocative opinion, interesting preliminary work, or a cool idea that will spark discussion at the poster session. To submit a poster, please send a 1-5 page(s) proposal, in PDF or PostScript, to sec07posters@usenix.org by June 23, 2007 * Get a preview of next year's news or present your own new work and get audience feedback at the Work-in-Progress reports (WiPs). Speakers should submit a one- or two-paragraph abstract to sec07wips@usenix.org by August 8, 2007. Whether you're a researcher, a system administrator, or a policy wonk, come to the 16th USENIX Security Symposium to find out how changes in computer security are going to affect you. Please see http://www.usenix.org/sec07/proga to register today! We look forward to seeing you in Boston, August 6-10, 2007. For the Security '07 Program Committee, Niels Provos, Google Inc. Security '07 Program Chair sec07chair@usenix.org P.S. Workshops will be held in conjunction with the main conference. EVT '07 and WOOT '07 will both take place on August 6. DETER 2007 will take place August 6-7. HotSec '07 and MetriCon 2.0 will both take place on August 7.

I can't talk about the specifics of the program, but let's say that it is a UI with many options to choose from on the main screen.

I knew I would get that question.  I can't talk about the specifics of
the program, but let's say that it is a UI with many options to choose
from on the main screen.  You can arrow to the different options, but as
soon as you try to execute one of the options (Enter) it will freeze.
It also freezes when you try to exit normally (Esc).

Thanks for the help.

Is it acceptable to run it via "strace -o /dev/null <program> &" or some such?

You may want to try running the program normally, cause it to hang, and only then attach to it with strace, using "strace -p ", to see what system call it was in the middle of processing. Attaching with gdb may also be an option.

X-BeenThere: plug@lists.phillylinux.org X-Mailman-Version: 2.1.5 Precedence: list Reply-To: Philadelphia Linux User's Group Discussion List List-Id: Philadelphia Linux User's Group Discussion List List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: plug-bounces@lists.phillylinux.org Errors-To: plug-bounces@lists.phillylinux.org Short version: does anyone have any thoughts/recommendations on "send it out to the clean-room" hard drive recovery services (e.g. On-track)? Long version: A neighbor has a hard drive that died suddenly and he'd like to recover some of the data. (Don't even ask about backups.) I got my hands on the drive and its behavior is--odd. My theory is that the drive's electronics suffered a component failure somewhere in the data path between the drive firmware and hardware. It was apparently working at 9:30 AM and just dead by 11:30 AM, with no known issues (no storm, etc.) and no previous warning signs. When I installed it as the only drive (IDE master), the test PC (Dell PE 350) BIOS didn't see the drive at all. So I threw in another drive and set it to master and the failed drive to slave. Then the PC BIOS could see the failed drive. As far as I can tell, the platters spin up fine. So I booted up Ubuntu and started poking around. fdisk can see /dev/hda (good) but not /dev/hdb (failed). Yet, /proc/ide/hdb is populated [1]. Yet, dd has been running for 14,000+ seconds and has copied 0 bytes (dd if=/dev/hdb of=/mnt/good/image.dd conv=noerror). I plan to let dd run overnight then try the freezer trick, just in case. But unless that changes things, it seems to me that SpinRite, or recover2000.com or whatever other home-use software solutions (as suggested by another list) won't help, since I can't even dd the raw data... Anyone disagree? So the only other option is one of the bazillion services e.g. at http://www.google.com/search?q=drive+recovery+services. So any thoughts/recommendations on these? This is a home user looking to recover only 1-2 folders worth of data. No pics, mp3, or anything else, just some data, and money is a concern. ________________________ [1] /proc/ide/hdb/* ==> /proc/ide/hdb/cache <== 2048 ==> /proc/ide/hdb/capacity <== 80293332 ==> /proc/ide/hdb/driver <== ide-disk version 1.18 ==> /proc/ide/hdb/geometry <== physical 16383/16/63 logical 16383/255/63 ==> /proc/ide/hdb/identify <== 0040 3fff c837 0010 0000 0000 003f 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0003 1000 0039 4e41 5236 3135 395a 4d61 7874 6f72 204e 3430 5020 2020 2020 2020 2020 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 8010 0000 2f00 4000 0200 0000 0007 3fff 0010 003f fc10 00fb 0100 2dd4 04c9 0000 0407 0003 0078 0078 0078 0078 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 00fe 001e 7c69 7f09 4003 7c68 3c01 4003 007f 0000 0000 0000 0000 6b00 c000 0000 0000 0000 0000 0000 2dd4 04c9 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0001 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 74a5 ==> /proc/ide/hdb/media <== disk ==> /proc/ide/hdb/model <== Maxtor N40P ==> /proc/ide/hdb/settings <== name value min max mode ---- ----- --- --- ---- acoustic 0 0 254 rw address 1 0 2 rw bios_cyl 16383 0 65535 rw bios_head 255 0 255 rw bios_sect 63 0 63 rw bswap 0 0 1 r current_speed 0 0 70 rw failures 0 0 65535 rw init_speed 0 0 70 rw io_32bit 0 0 3 rw keepsettings 0 0 1 rw lun 0 0 7 rw max_failures 1 0 65535 rw multcount 0 0 16 rw nice1 1 0 1 rw nowerr 0 0 1 rw number 1 0 3 rw pio_mode write-only 0 255 w unmaskirq 0 0 1 rw using_dma 0 0 1 rw wcache 1 0 1 rw ==> /proc/ide/hdb/smart_thresholds <== ==> /proc/ide/hdb/smart_values <== ---- cut here ---- Thanks, JP ----------------------------|:::======|------------------------------- JP Vossen, CISSP |:::======| jp{at}jpsdomain{dot}org My Account, My Opinions |=========| http://www.jpsdomain.org/ ----------------------------|=========|------------------------------- Microsoft has single-handedly nullified Moore's Law.

Anyone disagree? You could try to dd a portion of the disk instead of the whole thing. If this completes then you might be able to carve some of the data from the image. You can check dd's status during the process by (from the man page): Sending a USR1 signal to a running `dd' process makes it print I/O statistics to standard error and then resume copying. $ dd if=/dev/zero of=/dev/null& pid=$! $ kill -USR1 $pid; sleep 1; kill $pid 18335302+0 records in 18335302+0 records out 9387674624 bytes (9.4 GB) copied, 34.6279 seconds, 271 MB/s What type of box did this drive come from? Some manufactures prevent data from being read if the drive is removed, so you might need to image it in the original tower (use Knoppix).

The total cost was about $2,000 and the drive was an old ~4GB SCSI drive. I don't think Ontrack charges a fixed rate per MB. There was a charge for just looking at the drive (about $135 or so) then a charge for the data recovery, plus a $5 charge for a DVD to put it on. This was back in 2002-2003 so I'm not sure what the current costs would be. ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug From plug-bounces@lists.phillylinux.org Fri Jul 06 22:57:12 2007 Return-Path: Delivered-To: historian@netisland.net Received: (qmail 30929 invoked from network); 6 Jul 2007 22:57:09 -0000 Received: from unknown (HELO ellesmere.netisland.net) (127.0.0.1) by localhost with SMTP; 6 Jul 2007 22:57:09 -0000 Return-Path: Delivered-To: alias-plug@lists.phillylinux.org Received: (qmail 30895 invoked by uid 107); 6 Jul 2007 22:57:07 -0000 Received: from smtp.jpsdomain.org (HELO smtp.jpsdomain.org) (66.92.238.114) by qpsmtpd.netisland.net (qpsmtpd/0.32) with ESMTP; Fri, 06 Jul 2007 18:57:07 -0400 Received: from [192.168.99.121] (unknown [192.168.99.121]) by smtp.jpsdomain.org (Postfix) with ESMTP id 57FCF7C8020 for ; Fri, 6 Jul 2007 18:56:58 -0400 (EDT) Message-ID: <468EC8B0.1040006@jpsdomain.org> Date: Fri, 06 Jul 2007 18:56:48 -0400 From: JP Vossen User-Agent: Thunderbird 2.0.0.4 (Windows/20070604) MIME-Version: 1.0 To: plug@lists.phillylinux.org References: <468DC51F.6040001@jpsdomain.org> In-Reply-To: <468DC51F.6040001@jpsdomain.org> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Subject: [PLUG] Re: hard drive recovery services?

Thanks to everyone who replied. It turns out this is a known problem with Maxtor drives: http://forums.actionfront.com/showthread.php?t=339 "If you see this drive as N40P, you definitely don't have electronics problem. So PCB swap likely won't help. Drive is locked in the "Safe mode" , by one reason or another. It's likely have firmware problem but could be a problem with heads/preamplifier , which will require internal work. Slight possibility exist that r/w channel chip is died and but all other components on PCB are working, in that case PCB swap will help... but that is very low chance, since majority of PCB work to allow it to be detected as N40P."

I have been reading,  "http://en.wikipedia.org/wiki/Portmap"

Does anyone know exactly what this service does, and the importance of it for NFS? I know NFSV4 does not need Portmapper, so why does NFS Version 3 and 2 need it?

Thanks in Advance!

A friend emailed me yesterday looking for 2 or 3 Cu GBIC adapters. Note, not SFP sized, old-skool big sized. Anyone have any laying around? For the more Cisco-inclined, we're talking about WS-G5483 GBICs. Other brands should work as well, but that's the type we're talking about here. He's hoping for free, but would settle for cheap. :) He's not from the area (Chicago), but either I could get them from you and pass them on to him when I see him in 2 weeks or, he could probably hook you up with a fedex # to use to get them to him, or possibly just send you the $$ to cover shipping.. I'm out of town until Wed, so the earliest I'd be able to pick them up is Thursday. While I live in Marlton, hitting the other side of the river (as long as it's not insanely far) is totally in bounds..

NFSv3 services by default does not listen on a regularly assigned port -
they ask the OS at startup for a random port, and then listen on it.
portmapper exists to translate RPC call requests into port numbers.
This way, when one machine needs to know how to do an RPC call to, fo
instance, figure out the files in a directory, the application talks to
portmapper, which figures out what port the relevant service is on, and
then network traffic can happen.  It does seem a bit arcane to me as
well.

The smb protocol (which the samba project has painfully reverse engineered) does use RPC. The difference is that smb uses well known ports, so there is no need for a map daemon. nfsv4 also uses well known ports for most things, so the need for portmapper is getting less and less. --=20 -------------------------------------------------------------------------- | Stephen Gran | Everything will be just tickety-boo | | steve@lobefin.net | today. | | http://www.lobefin.net/~steve | | -------------------------------------------------------------------------- --9jxsPFA5p3P2qPhR Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFGkqtVSYIMHOpZA44RAnivAJ40mazMyuN89TMKJihPiOq/vAB63gCg3FPa ah/zyxym2U/XU2wq/yStfY8= =QfUD -----END PGP SIGNATURE----- --9jxsPFA5p3P2qPhR-- --===============2100022856== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ___________________________________
