scrollkeeper loading external (online) DTD

2003-01-08 Thread Sebastien Chaumat
Hi,

 This a real example : 

 The xbill package contains : /usr/share/gnome/help/xbill/C/xbill.xml

 In this file the DTD is refered by an absolute external link :

http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd"; 

 Thus : scrollkeeper-update blindly connect to www.oasis-open.org to get
the docbookx.dtd.

 I can trust signed debian packages but I can't trust 
www.oasis-open.org.

More than 18 files in /usr/share/gnome/help/ induce this download.

I'am about to make bug report against scrollkeeper (for acting blindly,
and dowloading the same file more than once) and against packages that
provides the xml files (for using external DTD instead of provinding
it)...

Your opinion?

Cheers,

SEb

CDs are different from floppies.  It's normal that different CDs have
different sizes (and AFAIK, there's no clear end marker, so I wouldn't
be surprised if the readable area is larger with some drivers than
with others).

I have done some google searching and I believe the culprit might be
gnutella. Take a look at this search (try google's cached files since the
servers are no longer up)

http://www.google.com/search?hl=es&ie=UTF-8&oe=UTF-8&q=6352+gnutella&lr=

You will see that the listing for many servers/clients in the network are
usually port 6346 [1]. But it seems port 6352 is also used sometimes.

Those are standard PHP errors, but it looks like there were a LOT of

RE: raw disk access

2003-01-08 Thread Colin Ellis
This may have something to do with the block size.  I'm not sure of the
default options for dd, but it does allow you to specify the size of blocks
you are copying.

Another thing to check is the options for padding blocks for newline
terminated records.  You might also need the 'noerror' option.

Good Luck :)

i thought originally that dd would work and tried to 'image'

The best that can be achieved is via 'dd'.

however it is actually impossible to get _real_ raw disk access due to the
disk IO controllers.  As far as I know, all disk IO controllers have
automatic data correction etc and so do hard disks.  An accurate copy of the
surface of the disk cannot be gained by this method.

Has anyone any ideas on whether it's possible to bypass the automatic checks
performed by the IO controllers?

Subject: raw disk access


Hi.

As a Debian user, i am posting to this list first in the hopes
that what i am looking for can be found as a Debian package.

i am looking for forensics tools that can be used in computer
crime investigations, and am particularly interesting in a tool
that provides raw drive (hard, floppy, CD, DVD, etc.) access in
order to create complete and accurate drive images.

If such a tool does not exist within Debian, is anyone aware of
any application (GPLed, please) that does?  Failing that, i am
willing to write my own tool, if necessary, and would appreciate
any pointers to good reference material (raw drive access and
how to work with the images created).

If it helps, i am running with the latest 'unstable' packages.

Many thanks.

Hi,

sorry for replying to my own posting, but of course it should read

* /var/log/lastlog not world readable

instead of 

> * /var/log/wtmp not world readable

Cheers, Thomas
