Hi Shlomi,

I saw previous emails sent to you in private end up back on the mailing
list. You seem to be very insisting on that point, it's even included in
your signature. I reserve the right to be selective on what I share on
public forums, and your insistence that emails to you be made public
prevented me from sending you the feedback.

Short consulting gig (programming with BISON/Flex)

2017-08-10 Thread Aviram Jenik
Hi,

We're looking for a consultant that can help us with a short gig to figure
out why
a piece of BISON/Flex code (used to render code into an interpreter)
compiles under Debian 7 but not under Debian 9.

The error is pretty vague so I rather not paste it here as it doesn't
actually helps anyone who hasn't seen the full code.

Any referrals would be appreciated; we're in Ra'anana industrial area.

Re: Skimping on AWS EC2 bills

2015-01-07 Thread Aviram Jenik
I'm not an AWS expert and would love to hear from those who are. But we do
have a few (dozen) instances on AWS.

We have them running 24/7. I get that you could start and stop on demand,
but don't get how you would do that without changing the way you work in a
drastic way (compared to a physical machine). To save costs, buy a
'reserved instance'. You are paying up front for 1-3 years (I recommend 3
years) and then paying a very very low cost per hour. If your load is low,
buy the 'low load' machine to save even more costs (but then you pay hire
fees if you cross the threshold). I don't know how this works well enough -
we always buy the 'high load' instance and buy them for 3 years; the total
average cost is equivalent to what we would have paid for the hosting and
so the hardware is free.

Re: Question about how to make a living from open source

2014-09-18 Thread Aviram Jenik
It's not clear (at least, not to me) what you're asking.

You want something that has no risk, does not require too much hard work,
but pays well. And then you want to further restrict the search space of
this invisible universe to open source only. How is that middle ground?

Decide which of these constraints you're willing to free, and perhaps
people can help you with some experience. If there was an open source way
to make money easily with no risk and little work I promise you we wouldn't
be telling you about it since we would be too busy drinking cocktails in

 Subject: Question about how to make a living from open source

 Hi All,I am in need of assistance.

 I am currently working as a freelancer coding stuff in a company.
 However, although I am making good living, this does not scale much
 (and promotion is out of the question :) ).

 Anyway, I am looking for ways to scale.

 A different way to say the same thing:
 You can choose to be an employee in which case your earning potential is
 limited to what the current market value of someone with your skill set is.
 Doesn't scale but does provide you with benefits, a guaranteed salary
 and a corporate culture for advancement.

 Or, you can choose to work for yourself. This have several variations:
 1. Working as a contractor - Generally this allows you to charge a higher
 hourly rate. The down side is you have to provide your own benefits,
 accounting, etc. You also lose the stability of it being someone else's job
 to generate work for you. This also does not scale as you are limited to
 the number of hours a day you can work and the going market rate for the
 skill set you have.

 2. Produce a product - Build a better mouse trap and sell it. This is not
 necessarily in line with the open source way of doing things. However, it
 is a common business plan. This has the potential to scale as you can
 develop the product once and sell it many times. You have the significant
 risk of startup and development costs and whether the product will be
 successful.

 3. Provide a service - Along the lines of the idea you suggested of
 hosting complex solutions. This is similar to being a contractor but the
 focus is on marketing the service you provide rather you and your  skill
 set. This only has the potential to scale by having other people (employees
 or contractors) provide the service in the name of your company. Your
 profit is the cost you can charge the client minus the cost of the worker
 actually doing the work. You also take on the responsibility of generating
 enough work to cover the costs of the worker(s) and yourself. With all of
 the joys that Yonatan described in his email.

Re: [hopefully on topic] is SSH secure in default configuration?

2013-09-08 Thread Aviram Jenik
I'm only taking a wild guess here. To be clear, I have no inside knowledge
and my guess is probably as good as anyone else's. But if I had to bet this
is where I would put my money.

Either:

1. They have a 0-day against SSH (e.g. if you have ssh running they can
login to your box)
2. They are aware of a weakness in the openssh implementation, unrelated to
the encryption itself

Pressed against the wall, I would go for option 1. But I wouldn't rule out
option 2. I *would* bet against them being able to break the encryption
itself.

Why? Because obviously, it's much easier to break the implementation than
the encryption. I find it hard to believe the NSA can easily break AES or
3DES, and I find it easy to believe they found a flaw or weakness in the
implementation. It's that simple.
The question is encryption ABC safe is nowadays a purely academic
question and only academics care about them (no offense Oleg).

A quick note on Elyahu's list:

1. I don't think allowing root login is a huge issue
2. Likewise with password authentication
3. We rarely see SSHv1 being allowed in modern systems - I don't believe
that's been the default for a while now
4. Likewise, I think having SSHv2 only is the default for years (but I
could be wrong, of course)

 Hi,

 I am not hopeful to secure much of anything against the likes of NSA or
 GCHQ. However, my curiousity woke up when the latest
 NYT/Guardian/ProPublica pieces about NSA/GCHQ/friends compromising much
 of Internet encryption were accompanied by graphics like


 http://www.nytimes.com/interactive/2013/09/05/us/unlocking-private-communications.html

 Now, NYT is hardly a technical authority, but I assume they have
 technically competent sources and advisers. The above page lists Cisco,
 Microsoft (I wonder if they were the ones who outed Skype - chuckle),
 and EFF as sources.

 I shrug at HTTPS/SSl/TLS/VPN/Skype,IM - nothing surprises there. The
 only part that is somewhat surprising (and particularly relevant to
 Linux-IL) is SSH. Why is SSH (on Linux) included and is the inclusion
 justified?

 A glance at man 5 ssh_config (or man 5 sshd_config) reveals the
 Ciphers section and the default preference list for v2 ciphers, with
 AES-128 in the leading position. Can any security/cryptography guru here
 (Or? Aviram? Noam? anyone?) confirm or deny that AES-128 may be suspect?
 AES-256 still seems to be regarded as NSA-safe (but not RC4?

 http://www.theregister.co.uk/2013/09/06/nsa_cryptobreaking_bullrun_analysis/).
 Is
 it prudent to reconfigure ssh/sshd to prefer AES-256? Can anyone comment
 on performance impact of using AES-256 vs. AES-128 for the usual
 scenarios?

 I am not sure I quite understand the implications of AES-128 and AES-256
 both being NSA-approved as Type-1/Suite-B algos. I'd hope that NSA
 assume that anything they can break others can break, too, so Type 1
 product being defined as endorsed by the NSA for securing classified
 and sensitive U.S. Government information, when appropriately keyed
 hopefully means NSA cannot break it. However, there is also
 Type-1/Suite-A... Suite A being seemingly regarded as even more secure
 than Suite B (is it?) goes against the common cryptographic wisdom that
 says disclosed algos deserve more trust. Is it an indication that (at
 least) AES-128 may be somewhat vulnerable? Or is is only because AES was
 not historically NSA-sourced that it is in Suite B and not in Suite A?

 http://en.wikipedia.org/wiki/Type_1_product
 http://en.wikipedia.org/wiki/NSA_Suite_B_Cryptography
 http://en.wikipedia.org/wiki/NSA_Suite_A_Cryptography

 Back to NYT graphics: Another, more mundane possibility is that NSA's
 partial success against SSH (and/or OpenSSH implementation) means that
 SSHv1 and DES (and maybe the default triple-DES???) are vulnerable. That
 would not be a big surprise (at least the DES part).

 I am not changing the default SSHv2 Ciphers configuration unless someone
 I trust says AES-128 is suspect. And maybe not even then... But
 curiousity is killing this cat...

Re: Printing with Cannon MF4150

2012-04-19 Thread Aviram Jenik

 I tried both before and after, but like I mentioned the ubuntu tutorial I 
 linked to only mentioned one symlink.

Looking at my system, I only linked:
/usr/lib64 - /usr/lib

and I did that BEFORE installing the deb files.

Also, contrary to what I told you before, I am looking at my packages
and they are 2.40.

 Did you need to install cannon-bjnp or does the PDD file take care of that 
 for you? I'm running cups 1.5.2-5, I read that earlier versions of cups might 
 work better with this printer. Do you remember if you needed to downgrade 
 cups?

I did not need to downgrade cups and did not install the bjnp. I
didn't use the PPD either, just picked the printer out of the list (it
was detected automatically)

Printing with Cannon MF4150

2012-04-18 Thread Aviram Jenik
Eliyahu,

I've had mixed success with this printer; while the drivers do
eventually work, they sometimes require some fiddling. The
instructions unfortunately differ from version to version.

Is your system 32 bit or 64 bit? If 32, try version 230. It has .deb
files and should work out of the box.
If 64, a simple 'alien' does not work. There are dependencies that
need to be installed, and you need to symlink the 64 bit directory -
sorry, I don't have the instructions in front of me and could find it
in a couple of minutes of googling.

Also, reboot between attempts. Yes, that should not matter on decent
package installations, but it does matter here.

Re: External monitor can only copy laptop's built-in

2010-05-21 Thread Aviram Jenik
I've had some success configuring xorg.conf or using the system settings 
configuration for the dual display. But that sometimes works, sometimes 
doesn't, and hard to know why (not to mention a reboot changes things back 
again) and very hard to give a 'recipe'. It seems to be very 
version-dependent or buggy to the point where it works for some people on 
some video cards, and may not work for others.

The best solution I could find is xrandr, as Omer mentioned. xrandr *always* 
worked for me, even in complex configurations.

Things to note: change the resolution/refresh rate of each screen to their 
maximum (start with xrandr -q to see where you stand, and then 
xrandr --output LVDS --mode YYYxZZZ). It also has switches to put one screen 
on the right or left of the other, and it all happens immediately. Of course, 
as Omer mentioned, make sure the virtual display settings are big enough for 
(1680+1680)x1050.

Also check out the 'addmode' switches that allow you to set a very specific 
configuration (refresh rate, etc) on each of the monitors to really make sure 
you are taking advantage of it.

The downside of xrandr is that you have to manually do it., and you lose the 
wonderful auto-detect features of xorg. Then again you can map it to a 
hot-key and make it work with a single click of a button.

 The KDE System Settings tool sees the external VGA monitor as the

 configure the LVDS to the right of the external VGA monitor, the LVDS

 What must I do to get these monitors configured?

That's pretty much what you wrote. 

Every Ubuntu release has a wiki page with known issues. Ubuntu has a bug

and are open - *for your hardware*. If you want an informative list, that's 
the one. Everything else is personal experience from a tiny sample size that 
might be completely different from your own use case.

To get some meaningful response, it would help if you specify your hardware

problems you were having and most importantly, what is your alternative to 
Ubuntu.

 (Obviously, this is *not *ment to be a discussion (or even worse, a flame

Ubuntu has been around for almost 6 years. I doubt there is something

Answering my own question. This appears to be a known bug:

The workaround is to modify the console-setup variables that are read

Change:

 As far as I know, xorg.conf does this. My logic says that a fork should be

 Other way to check if there is a script that runs is to use the following

Dual screens / keyboard layout

2009-05-20 Thread Aviram Jenik
To hijack the 'ubuntu sucks' thread (though it really does suck), here is a 
tip, and two questions:

- For the guy that asked about dual screens not showing the best resolution, 
open your terminal and type:

xrandr --auto

if that doesn't get you the optimal resolution, do:

xrandr -q

see what your monitor is called (VGA, or TMDS-1 or something similar) and 
then do:

xrandr --output TMDS-1 --auto

This will set your resolution to the best xrandr thinks it can do, using the 
current 'virtual screen' settings. If you want to over rider what xrand 
thinks it's best do:

xrandr --output [bla] --mode 1280x1024 (or similar)



Now my question: X automatically detects when I plug in the 2nd monitor. I'd 
like to run xrandr when that happens to set it to the 'correct' resolution. 
Does anybody know what scripts runs on this hot-plug detection?


Second question: When I connect a USB keyboard it does not have the correct 
layout. I need to go to the keyboard layout and hit 'apply' for it to enforce 
the layout on the USB keyboard as well. Since xorg.conf is now pase', does 
anyone know how to solve this issue?

Re: Israeli ISP blocking outgoing SMTP

Noam didn't say blocking port 25 for everyone is a good thing or that he likes 
it - just that this is what ISPs in Europe and the US are doing that to fight 
spam.

What Noam said is that ISPs have a responsibility to prevent spam being sent 
from their hosts. He also said that blacklists may not be the smartest thing 
in the world, but they are deployed and in use - once that's done it's the 
ISPs responsibility for its users to not be listed. It is unfortunate ISPs 
choose blocking port 25 as the easy way to do that, but like I said it's the 
current common practice.


By the way - just to set the Linux-IL record straight - Imri has been 
extremely helpful to us in several abuse cases we contacted him with. It 
wasn't necessary for him to do that (that's what the abuse desk is for) but

 Not in my experience. That is, unless I grossly misunderstand the
 problem. In my mind, this means that the problem occurs when you
 configure a foreign server as your SMART_HOST while connected to the
 octal 11 Israeli ISP.

[...]

 I have just returned from a trip to Europe. I sent emails, using my
 laptop, from two different Western European countries, from a hotel,
 from coffee shops, from occasional unidentified public Wi-Fi spot,
 etc

You just got lucky.

Some ISPs will only block you after a number of outgoing port 25 connections 
to different IPs. Others block outgoing 25 completely. 

Try and remove the SMART_HOST to have sendmail send emails directly (as the 
Internet was built to allow) and revisit those ISPs. You'll probably be 
blocked. Leave SMART_HOST in and try a few more ISPs in Western Europe and 
the US and you will probably get blocked. 
See for example:
http://www.postcastserver.com/help/Port_25_Blocking.aspx



 In general, this does not make much sense. Imagine a typical
 Windows/Outlook user who has his outgoing mail server (SMART_HOST
 equivalent) configured to something (by his company's IT people, he
 himself does not know what an outgoing mail server is,
 etc.). Imagine this person on a trip somewhere - he does not change
 his configuration, but he doesn't normally have any problems sending
 email.

 If the octal 11 Israeli ISP does it it is *not* following any common
 practice. Oh, and I agree it is stupid, as is blacklisting.

No argument there. It is incredibly stupid, but unfortunately unpreventable 
due to the sheer number of moron blacklisting services.

 slower and crashed more often.
  2. Linux distributions don't work. Even Ubuntu and other mainstream
 distributions simply do not work. Package testing is poor, and various
 programs do not integrate with one another. I often find myself having to
 fix things manually, usually by digging deep into various

 tend to break horribly, requiring a clean reinstallation.
  3. Usability as a whole is becoming less viable. Applications (at least

Re: OFFTOPIC: Re: Hebrew spam: what to do about it?

2009-02-08 Thread Aviram Jenik
Tal Kaplan, from pczlaw, was kind enough to give me a detailed explanation(*) 
about this matter.

First, to answer both Dotan and Boaz, it should be a relatively simple process 
to get 1,000 NIS for every incoming hebrew spam. Think about it as a gift 
from a stranger. The process is documented on the isoc site (link was given 
in some other post in this thread). Remember you have to prove very little 
(that you got the spam) while they have to prove a lot (that you gave them 
permission to send you spam. They need to actually PROVE it).

Second, involving a lawyer will not help - you need to sue in small claims 
court, since the 'hashaom' court will look at you strangely if you come 
claiming such a small sum. Neither hashalom nor small claims court set 
precedence so it doesn't really matter. The cost (legal and otherwise) in 
small claims is much lower. So for all these reasons small claims is the way 
to go unless you are going to file a TVIA IZUGIT which you probably don't 
want to do unless you have a lot of free time.

The only down side is that in small claims you have to file and appear 
yourself, without a lawyer. This is basically the reason I haven't done it 
yet. I'm saving my gifts^H^H^H^H^Hhebrew spam in a special folder for when I 
will have a few free hours to put it in the isoc tempate and go to small 
claims to file it. Spam keeps piling up in it and it gives me the feeling of 
a piggy bank. Oh, how things have turned.


(*) This is the explanation as I remember it. If there are inaccuracies it is 
probably my bad memory and not Tal's fault.

configuration should be changed for Cellcom - I think the windows 
instructions should make it clear where the differences are.


1. edit /etc/bluetooth/rfcomm.conf:

rfcomm0 {
bind yes;

# nokia e65
device your device mac address. Find it using hcitool scan;

channel 2;

comment nokia ppp;
}

'channel 2' is good for nokia E65. Your nokia may be different (though I doubt 
it)

2. Make these changes take effect immediately by:
sudo /etc/init.d/bluetooth restart

3. create /etc/ppp/peers/orange:
debug
noauth
connect /usr/sbin/chat -v -f /etc/chatscripts/orange-connect
disconnect /usr/sbin/chat -v -f /etc/chatscripts/orange-disconnect
usepeerdns
/dev/rfcomm1 115200
defaultroute replacedefaultroute
#user orange
#password orange

#nodetach


lcp-echo-failure 0
lcp-echo-interval 0
nomagic
noccp


Note that orange doesn't need a user and password.
Also, you may want to uncomment 'nodetach' to have the script run in the 
foreground and show you the errors while you're making it work.
Note that I have 'defaultroute replacedefaultroute' which means it will take 
over as the default route (this is useful, because if you bother connecting 
over bluetooth is because your regular gateway is not working or not working 
well).

Finally, the last 4 lines are the 'magic sauce' that may be different between 
providers and between devices. Regretfully the only real way to debug it if 
it doen't work for you is trial and error. Hopefully it'll work for you out 
of the box.

4. create:
 /etc/chatscripts/orange-connect
TIMEOUT 5
ECHOON
ABORT   '\nBUSY\r'
ABORT   '\nERROR\r'
ABORT   '\nNO ANSWER\r'
ABORT   '\nNO CARRIER\r'
ABORT   '\nNO DIALTONE\r'
ABORT   '\nRINGING\r\n\r\nRINGING\r'
''  \rAT
TIMEOUT 12

OK  ATE1
OK  'AT+cgdcont=1,IP,uinternet'
OK  ATD*99***1#
TIMEOUT 30
CONNECT 


The two lines (AT+cgdcont... and ATD*99...) may need to be changed for 
Cellcom

5. create /etc/chatscripts/orange-disconnect
ABORT   BUSY
ABORT   ERROR
ABORT   NO DIALTONE
SAY \nSending break to the modem\n
  \K
  \K
  \K
  +++ATH
  +++ATH
  +++ATH
SAY \nPDP context detached\n


This should probably be the same for all carriers


6. Test it with: pon orange
disconnect with: poff orange


Of course, this assumes bluetooth is working (should be a no brainer on 
ubuntu) and preferably the devices are paired to avoid stupid questions from 
the mobile device when connecting.

Works for me like a charm.

 Hi,
 I heard a story about how a program called

 amounts of email perfectly being restored.


From a brief glance it looks like a forensic tool, which means it probably 
accesses hard drive content of files that have been erased. Every HTML file 
you see went through the hard drive at some point, and so all your web mail 
was stored on the hard drive over the course of the hard drive life.

Whether the software is so good that it can recover the emails in perfect 
shape, I don't know - but the fact the files have a specific structure and 
predefined strings to look for makes the work of the forensic tool a lot 
easier.

 I find the idea that web mail is stored on the local disk over long
 periods weird.
 The web browsers does use a cache to speed up browsing but I assume that
 things like web mail pages get overwritten pretty fast. If not it would
 be possible to go into an Internet cafe or university and read all web
 mail read there in the past from the disk. This would be a huge security
 hole. Anyone got some solid information about what happens when you read
 webmail?

Webmail uses HTTPS which is not stored in the cache. It does, however, gets 
stored temporarily and then deleted. Anyone viewing the hard drive with 
forensic software will see it.


 My guess is that the above program was running and storing the webmail
 when it was being read not month later.

That's also possible. Like I said, I never heard or used this program and it 
could very well be snakeoil.

   Small trick, I noticed that most wireless networks here permit access
 freely to port 53 udp/tcp. So, I simply put a squid proxy on port 53, on

   I guess the next step would be to simply tunnel via port 53, and that

Kernel compilation oddities

2006-03-03 Thread Aviram Jenik
Hi,

On my previous laptop, I would compile the kernel once, and then if I need to 
compile the same kernel again (lets say I only changed something from being 
compiled-in to being a module) I would run make, and watch it skip the 
already-compiled parts quite quickly.

That way, recompiling an existing kernel would be much faster comparing to 
compiling a 'fresh' kernel, except for cases where a change affects most of 
the compilation (e.g. changing a setting that affects all modules).

Now, I'm on another laptop, and trying to do the same. However, every time I 
compile the kernel it takes amazingly long, and goes through a full 
compilation. Even running 'make' twice in a row makes it compile everything 
again. This happened to me with 2.6.13.1 and 2.6.15 and 2.6.15.4.

What should I check? I'm running Debian SID, BTW.

Thanks,

 Aviram

The following is nothing but a wild guess, but it's worth trying.

Over the years, I've had a lot of strange experiences with alsa and various 
sound cards. Almost all of them turned out to be simply a problem with the 
mixer volume.
For whatever reason, the alsa mixer sometimes changes the volume setting (of 
course, there's some external(s) program(s) that do(es) that, but every time 
this happened it turned out to be some other application). This might explain 
why when you reboot, the mixer settings are 'reset' and sound returns. So 
next time this happens, run
$ alsamixer
and see if ANY of the mixer channels changed (I do mean *any*).

Hope that helps.

 You can duplicate this on Debian by installing HAL, preferably from

 often). Yes, HAL/D-BUS are still pre-1.0, but they're already used in

Yup, that worked :-) But there are a few more steps to get it done really 
well.

Here's  what I did, in case anyone else needs it on Debian:

apt-get install hal hal-device-manager pmount
added the user to the 'hal' group

..and that's it :-)

The one thing that is missing from my original request is to have a window 
pop-up whenever the key is inserted. This is apparently a gnome-only feature, 
but is likely to be in KDE 3.5. In the meanwhile, there is a very convenient 
alternative. In Control Center - Desktop - Behavior - Device Icons click

Diskonkey automounting in debian under KDE

2005-11-24 Thread Aviram Jenik
Hi,

I'm looking for a way to enable disk-on-key to be *easily* automounted under 
KDE. Manual mounting currently works, but this is intended for a user who 
does not have access or knowledge about command line utilities.
The KDE media tab works sometimes, but does not unmount, and is hard to 
understand and use.

The best case scenario is an MS Windows-like popup when the diskonkey is 
inserted, with an auto unmounting when the usb stick is taken out.

I believe Ubuntu has something like that (can somebody confirm?). I'll switch 
to Ubuntu if I have to, but I'd rather understand how it works and duplicate 
this behavior under Debian.

STFW didn't produce anything beyond the standard non-GUI automounting 
utilities with tons of scripts to tweak it.

Close the service in question if you don't need it.

If you do, block access to the port (via iptables or tcp wrappers) except for 
a short list of known addresses or networks (e.g. your ISP). If you connect 
to this service from dynamic IP's, check out portknocking to sort this out.
If you absolutely must, allow access to it and block the offending network 
from accessing this port.

If you choose the last, feel free to write a quick script (I won't say in what 
programming language) to automatically block IP's that appear in the log 
files as failed logins. This block should be automatically lifted after 30-60 
minutes to allow you to make mistakes once in a while. Google for portsentry 
for an example of such a script, but writing one from scratch should be just 
as easy.

Need Computer Monitors for APCHII

2005-07-31 Thread Aviram Jenik
Hi,

For the upcoming August Penguin Hacking Contest (APCHII) we need 6 computer 
monitors. If you have a computer monitor (17 is preferred) that you can 
bring with you to the contest (if it's not clear - the monitor will be 
returned to you afterwards...) please let me know.

All monitor contributors will get an APCHII T-shirt :-)

OT: APCHII

2005-07-25 Thread Aviram Jenik
Hi,

The 2nd August Penguin Hacking Contest (APCHII) will take place on August 4th, 
in the August Penguin conference.

This year, we decided to go back to the old meaning of the word 
'hacker' (translating from the Hebrew Wikipedia):

A hacker is a term used to describe different types of computer experts. 
Especially, computer experts with the technical knowledge of bypassing 
borders.
[Hackers] are well known for their abilities in the programming field and in 
rapid programming of software


This is your chance to prove if you are a real hacker in the old sense - if 
you know your way around a Linux system, and can quickly program utilities to 
help you do what you need, come up and show your skills.

Unlike last year, the contest is individual - each person can sign up for the 
contest, and start solving the questions. There is a time limit of 30 minutes 
afterwhich you must vacate your sit to the next person in line - but you can 
return shortly after to resume the competition; this way you can listen to 
the lectures, enjoy the atmosphere and hack - all in one day...

Example to questions:
Easy question (1 pt): what is the current path
Medium question (2 pts): Convert the following hex file to ASCII
Hard question (4 pts): Use a format string attack to modify a certain pointer 
and execute an alternative function

There are about 50 questions in the competition, about a third of each 
difficulty level and some bonus questions.

Prizes:
The winners in the 1st, 2nd and 3rd places will get 500, 300 and 200 NIS in 
book coupons. Prizes are sponsored by Beyond Security.

[SOLVED] Openoffice and unicode and windows 98

2005-07-11 Thread Aviram Jenik
Ok. Here's a workaround to what seems to be an openoffice bug (and might have 
very little to do with Windows 98 or unicode).

Here's a summary of the problem:

On Thursday 30 June 2005 13:21, Aviram Jenik wrote:
 - Take a Hebrew excel file created on Windows 98
 - edit it with Openoffice on Linux (locale he_IL.UTF-8)
 - Send it back to the person who sent it to you
 - They try to open it and see squares instead of Hebrew letters (what
 probably indicates that it was transformed to Unicode which is not
 available on Windows 98, but I'm just guessing)

Actually, if you go to your own sent-items folder and try to open that file, 
you'll see question marks where the Hebrew letters should be. The solution, 
is to use:

File- Send- Document as Email

instead of:

File- Send- Document as MS Excel

Since we're editing a XLS file, OO will send the XLS anyhow. However, the 
first option sends it correctly (Windows 98 can open it) and the second 
screws up the encoding, or the Hebrew, or god-knows-what.

I'm using OpenOffice 1.1.4 on Debian.

 The same file can be opened on Windows 2000 (that supports Unicode) in the
 same office version. This happens repeatedly - i.e. every time I edit an
 excel sent from a Windows 98 and send it back the letters are shown as
 squares.

 Which Office version was that?

Office 2k AFAIK.

BTW, I tried the suggestion of saving it in Office 95 format - still no go.

Maybe a locale change would help? If so, to what?

 yes.  Windows 98 does Unicode differently - AFAIK it doesnt support
 UCS-2 like OO and MS Office require and modern OS's like NT, 2k and XP

But how do word/excel do their magic?

 you're screwed

 In what format did you save it from Oo ? Oo uses only unicode
 internally.

OpenOffice calls it Microsoft Excel 97/2000/XP

  Sure thing.
 
  That's why you can look your password file using a master password, or
  using gpg.

 My question was regrading applications that are not password-protected.


Then your examples (Mozilla password manager and Kwallet) were very poorly 
chosen.


 Since it is obvious that when I don't use a master password it will be
 possible to extract the passwords from my db, I want to prevent the
 trivial case or source-lookup (No anti-debugging tricks for the
 binary, yet :).


Any decent commercial product that encrypts something will require you to have 
a key as well. Nobody is stupid enough to think that if the source code is 
not available the algorithm is secret, and this is why you will never find a 
serious security solution that has a secret (=password, algorithm, whatever) 
in the binary. Some people call that security by obscurity, I call it the 
Chewbacca defense - it just doesn't make any sense.

And all of this has nothing to do with open source. I imagine you wouldn't 
want to use an encryption algorithm that doesn't break only if you try the 
trivial attacks on it as you put it. If this is the case, don't encrypt it 
and save yourself the illusion.

Hi,

I just got a USB frame grabber (ADS tech Instant VideoMPX). I couldn't find 
anything specific about it on google wrt Linux.

Any general tips/tricks? Is there a simple how-to on the subject?

Is there any hope? Does anyone have any experience (positive/negative) with 
USB frame grabbers?

 I could not find more information about this. I tought that the support is

Actually it does. My hibernate.conf contains:

Could you post the results here? It's sometimes tricky to find the right 
combination of swsusp and bootsplash patches that will work with a specific 
kernel version. If you find the right combination that works, it'll be 
helpful for others if you post what version of bootsplash and swsusp worked
