Special guest lecture at dc9723

DC9723 hosts Marc “van Hauser” Heuse (founded the renowned security research group “The Hacker’s Choice”, author of various famous security and pentest tools like hydra, amap, THC-Scan and more!) on Recent Advanced in IPv6 Insecurities!

The talk will be held on Wednesday, May 4 at Tel Aviv University Wolfson Bui., Rosenblat auditorium, at 20:00.

The talk is free, but please RSVP. This talk *Don't* replace the regular dc9723 meeting!

For more information, please visit http://dc9723.org/

Abstract:

Five years have past since Marc “van Hauser” Heuse initial talk on IPv6 insecurities 2005 and 2006. New protocol features have been proposed and implemented since then and ISPs are now slowly starting to deploy IPv6. Few changes have led to a better security of the protocol, several increase the risk instead. This talk starts with a brief summary of the issues presented 5 years ago, and... then expands on the new risks especially in multicast scenarios. As an add-on, discovered implemention security issues in Windows 7/2008, Linux and Cisco will be shown too. Lets hope patches are out until the conference, if not – they had enough time. All accompanied with GPL’ed tools to and a library: the new thc-ipv6 package. rewritten, expanded, enhanced.

Marc “van Hauser” Heuse is performing security research since 1993, having found vulnerabilities in software like firewalls, DNS servers, SAP middleware, etc. and is the author of various famous security and pentest tools like hydra, amap, THC-Scan, secure_delete, SuSEFirewall and many more. He is performing security research on IPv6 since 2005 and has spoken on many conferences on this topic since then, among these are the CCC congress (Germany), Cansecwest (Canada), PacSec (Japan) and many more international conferences, and additionally has programmed the solely available pentest toolkit for ipv6: the thc-ipv6 protocol attack suite. In 1995 he founded the renowned security research group “The Hacker’s Choice”, which was the first group to e.g. crack A5 GSM in 2006 within a minute. Since 1997 he is working as a security consultant in the top-5 enterprise consultant companies, since 2007 he is working as an independant security consultant.

OT: Laserdisc player needs a new home

Please excuse the OT, but the hardware geeks here just might be interested.

An associate in Be'er Sheva has a Laserdisc player in like-new
condition (and discs) that he needs to dispose of. If anybody wants it
then send to me your contact info and I'll pass it on to him.

[HAIFUX LECTURE] vIOMMU: Efficient IOMMU Emulation by Nadav Amit

On Monday, May 2nd (TOMORROW), at 18:30, Haifux will gather to hear Nadav Amit talk about

   vIOMMU: Efficient IOMMU Emulation

Abstract

Direct device assignment, where a guest virtual machine directly interacts with an I/O device without host intervention, is appealing,because it allows an unmodified (non-hypervisor-aware) guest toachieve near-native performance. But device assignment for unmodified guests suffers from two serious deficiencies: (1) it requires pinning of all the guest's pages, thereby disallowing memory overcommitment,and (2) it exposes the guest's memory to buggy device drivers.

We solve these problems by designing, implementing, and exposing an emulated IOMMU (vIOMMU) to the unmodified guest. We employ two novel optimizations to make vIOMMU perform well: (1) waiting a few milliseconds before tearing down an IOMMU mapping in the hope it will be immediately reused (``optimistic teardown''), and (2) running the vIOMMU on a sidecore, and thereby enabling for the first time the use of a side core by unmodified guests. Both optimizations are highly effective in isolation. The former allows bare-metal to achieve 100%of a 10Gbps line rate. The combination of the two allows an unmodified guest to do the same.ools used to track and count I/O (including - why is process-based I/O accounting so tricky).

================================

We meet in Taub (CS Faculty) building, room 6. For instructions see: http://www.haifux.org/where.html

Attendance is free, and you are all invited!

================================

Future Haifux talks include:

16/5/2011 The anatomy of a PCI/PCI Express (Linux) kernel driver by Eli Billauer
30/5/2011 How to Spread Knowledge Throughout the World While Wearing Only Your Slippers by Tomer Ashur.
13/6/2011 SSD fundamentals by Amit Berman
============================================================

We are always interested in hearing your talks and ideas. If you wish to give a talk, hold a discussion, or just plan some event haifux might be interested in, please contact us at webmaster-E9S1XMMTbEgdnm+yROfE0A@public.gmane.org

Automatic crop and rotate scans?

Hi,

I have a flatbed scanner (by HP) attached to my Linux machine, and I often
need to scan rectangular items such as photographs, CD inserts, and the
occasional piece of paper.

At the moment, I follow a tedious manual process to do that: The scanner
generates a big image of everything it sees on glass window, and then using
Gimp I manually rotate the image (because I can't place it on the window with
100% precision) and then crop it to the rectangle.

Supposedly, Photoshop has an "Automate->Crop and Straighten Photos"  feature
(see http://www.photoshopessentials.com/photo-editing/crop-straighten/)
but I couldn't find such a feature in Gimp.

I was really surprised that I couldn't easily find some program to do this
automatically: The program would recognize (using a relatively simple algorithm)
the foreground rectangle in the image, rotate it to be perfectly horizontal,
and then crop the image to it.

Does anyone know of such a program? Obviously, it needs to be free software
running on Linux. Bonus points if it's a command line program (a la netpbm
or imagemagick) and not an "integrated" GUI program. Extra bonus points if
it's a pipeline of netpbm or netpbm-like tools :-) But any other sort of
(free) solution would also be acceptable.

Thanks,
Nadav.

Re: Automatic crop and rotate scans?

I'm using PHPSANE (http://sourceforge.net/projects/phpsane/). It doesn't do auto crop but I can see on my browser whats the pic and with 2 clicks to decide which part to scan.

Hi,

How does your process deal with the inevitable need for rotation?

I can never align the photo on the scanner with 100% precision, so I always
need to rotate. I'd prefer not even to bother with alignment, and be allowed
to just "throw" the photo on the scanner (even at 30 degree angle, if it
happens that way) and run "scan", and that's it.

Upgrading Android Under Linux

Hi all,

I recently switched from Nokia N97 to Samsung Galaxy S GT-I9000. It came with Orange's ROM (Based on Android 2.2). 

It is lightning fast compared to my "old" N97, but still - it hangs and has a bunch of Apps I do not need or like...

I'd like to upgrade it to version 2.3.3 (Gingerbread). Can any of you tell me how to do it under Linux? I am running Ubuntu 10.04.

I found out that Heimdall is the equivalent to Odin, but I get a dependency error on the C Libraries when I try to install it.

Thanks!

Amichai.

Re: Upgrading Android Under Linux

If you're inclined, check out the CyanogenMod ROM.  Works great for
me, much better than (*&%$) carrier-branded firmware.
