The reason I had said anything is
that when I do forensic work I used to just do MD5's of files, but it
has gotten called to task in court so we now use both MD5 and SHA1
hashes as it is NP-complete to find a collision in both of them for
the same file.


Finding collisions for both MD5 and SHA-1 together is actually
NP-complete and not just NP?  That's an significant result that would
affect the design of protocols using hashes.  Do you have a citation
for that?


I would be interested in a proof for that as well, esp if this was true 
for _all_ collisions.

Makefile troubles w/ Xerces-C 2.7.0

[Moritz Kiese]

Greetings,

I have a little problem in getting Xerces-C 2.7.0 to compile:
After seeting XERCESCROOT to the correct path and running
./runConfigure -p netbsd
in $XERCESCROOT/src/xercesc (which runs w/o obvious errors) firing up a
simple

connect to such routers? the sangoma, accoom, etc. cards are pretty pricey.


That is highly dependent on the technology your ISP is using underneath. 
In case you already have the 1721s just continue to use them, but remove 
functionality (i.e. routing) from them --- I recall them as rather simple 
but solid hardware for terminating circuits.



The cheapest way that I can think of would be to get your ISP to provide
you some sort of Metro Ethernet or Ethernet over TDM solution.


That might be true, but this still depends on how your contract is (e.g. 
are you renting the 1721 from your ISP or are they yours)... In case your 
ISP provides them, switching to some kind of Ethernet would exactly do the 
same thing I suggested above --- the 1721 would simply act as 'dumb' line 
terminators... Otherwise your ISP would probably charge you something for 
the TDM termination equipment (EoTDM) or you would have to buy some very 
specific ethernet equipment (at least the 'right' type of GBICs, which 
might be as expensive as line cards).


As this is rather OT contact me off-list for further questions.

LUN-Probing on Multi-LUN Devices

[Moritz Kiese]

Greetings,

I just hooked up a rather old 6x CD-changer (Pioneer DRM-624X) to my 
SUN Ultra 1 (fast SCSI provided by a combi SBUS card with additional esp, 
le & cereal). The CD-changer usually presents its six cds at six different 
devices appearing under six LUNs, however neither 4.0 GENERIC nor a custom 
kernel with an additional


option SCSIFORCELUN_BUSES=0x0001

which I vaguely remember from an elderly discussion about multi-LUN 
devices on misc@ seems to find more than the first cd (cd1) of the six 
(which seems to be working fine).
In case it helps: Under Lunix and (IIRC) Slowlaris this beast appeared 
under six different LUNs, generating six cd-devices. All devices could be 
mounted simultaneously, but only one at a time could be read of course. So 
I wonder whether there is some way to force LUN probing on all devices?


Any hints highly appreciated,
Moritz.

Re: Unexpected Busfrees w/ Adaptec 2940 U2W and Raidframe

[Moritz Kiese]

Greetings,

just for the record, I never managed to solve this problem, but the
problem exists with the latest OpenBSD and FreeBSD incarnations of this
driver as well as under Linux (for the sake of simplicity Gentoo 2005.0
boot-cd).
Switched to an Adaptec HW-RAID and the damn thing is working now.

Best regards and sorry for wasting your bandwidth (again),
Moritz.

Intel 82801FB AC97 not configured?

[Moritz Kiese]

Greetings,

do I have any chance to get the above mentioned on-board sound on a (maybe 
too) new-ish PC running --- googling showed quite a few dmesg's with 
identical 'not-configured' lines?


$ man 4 auich only mentions support for the 'EB' version of the bridge.

Of course upgrading to CURRENT will be considered if helpful.

As usual any hints will be highly appreciated, best regards,
Moritz.
