Re: Feedback about HOT as an isp

2014-04-18 Thread Michael Ben-Nes
So now I use HOT for the infrastructure. I got the 100mbit download  2mbit
upload.
The line is stable and fast though I understand the quality changes from
place to place depending on the local infrastructure.

The latency to HOT speed test server is 17ms

 On the same subject:

 I am using Bezeq as infrastructure @ 15Mb and 014 as the provider at the
 same speed. Somehow I get a high latency when accessing sites, both in
 Israel and abroad.

 How can I check for the exact cause?

  As a guess, your latency is high because you are NOT paying for a
 better service package. The cheapest is the gamer's which will cut things
 down considerably. Last summer I changed my line from 012 with a gamer's
 package to CCC without. Latency is much lower.

 IMHO the program which is most affected by latency is BitTorrent.

The upload was great. True 3M in most reasonable Israeli servers. It was
slower to abroad but it its expected.

 Well,
 The upload of 3mbit (of bezeq was great for backup and other uploads).
 Now I have 750k or so :(

 Was/is the upload truly 3M, as far as I know they promise best effort but
 rarely reach promised speeds especially in upstream speeds since most
 customers barely care about it, it more overbooked and lower priority.
 That said I also like having 1M or more upload when and where possible.

 The high DL is a big plus when I need to DL updates and big images

 And also important, the ping is reduced

 If it's 15 megabit or below, you've probably been upgraded to NGN. NGN
 uses vDSL equipment which can run (poorly) in aDSL-2 emulation mode.
 Instead of informing people of the problem, they just wait for them to

 חנונים are nerds, there's a difference.
 http://www.nerdist.com/2010/03/geeknerddorkdweeb-venn-diagram/

 I think what people object to here (or at least what I object to) is the
 entire premise of the whole show.
 There are a few base assumptions here which are, imo, not necessarily true:

1. All geeks are men.
2. By inference, no pretty women are geeks.
3. Men geeks want an air-headed pretty woman as their significant other.
4. Men geeks are incapable of talking to and impressing a woman on their
 own, and therefore need a tv show to do it for them.

 The whole show is degrading and embarrassing to any intelligent person, men
 and women alike. The only possible reason I can see for wanting to
 participate in this show is to say Look Ma! I'm on TV! Which is a
 boneheaded reason.
 I think that's why anybody who does participate should not affiliate
 him/herself with any self-respecting geek organization.

 the APEX T328B which is a GeniaTech T328B with an unsupported tuner chip and
 the second is sold under the brand name Innova at Home Center.

 Since the Innova unit was on sale for a week for 99 NIS and went up to 199
 and has stayed there, I don't think many have been sold. Did anyone buy one,
 or know anyone that did? It looks different than the APEX, but who knows

  dd has a --sparse flag which makes it not copy empty space.

 I don't see such a flag in the man page.

 partimage avoids copying any free block (block marked as free by the
 file system). If that block also happens to be zeroed out, dd is not
 aware of such details. And frankly can't safely be aware of them if Hetz
 want to copy a mounted partition.

 Also note that if you use dd to copy a mounted partition, you copy
 different parts of it in different times. This is tricky at best. Unless
 you e.g. use an LVM with a snapshot.

 tar (or any other backup of files) is safer. Even there you don't get a
 complete snapshot of the system. But at least every file is valid.

 As I said earlier in this thread, I tried Greasemonkey. Unfortunately, I've
 found no way to make changes to an existing Javascript routine using
 Greasemonkey. Even if I could do so, there is the little problem of doing
 the
 change BEFORE the browser parses the Javascript code, so that the fixed
 version of the routine will run.

 If you (or anyone) know(s) a way to achieve this please let me know.

 I'm a die hard capitalist, I believe you should go with whomever gives you
 the best service for the best price.

 But Bezeq and Netvision are huge companies, and yet they offer not one
 thing more than the small ISPs (those that are left).

 I remember being a customer of ACT.com and couldn't have been happier.  The
 moment they were bought by BBL service turned to crap.  Connections wouldn't
 stay up, VOiP quality declined, and service requests (what few I'd needed
 under ACT) took days instead of minuets.

 On top of all that ALL larger ISPs in Israel block ports and use traffic
 shaping.

 It's insane that after I've paid BBL for a connection of a 5Mb that I need
 to pay them another 20NIS for a gamers package so that VOiP can work (when
 VOiP could work as well on an unthrottled line 1/4 the size).  If they
 downgrade P2P traffic, I understand that.  I don't like it, but I understand
 it.  But VOiP is not bandwidth intensive standards, and doesn't degrade the
 network.  Gamers, even hard core gamers, aren't online enough that they
 saturate their slice of the bandwidth.  THE ONLY REASON to downgrade traffic
 for VOiP or gamers is to justify taking more money from them.

 The large ISPs have every opportunity to offer a superior product. They
 have efficiency of scale on their sides.  But at the end of the day small
 businesses are still offering a better service, because they don't have the
 marketing capacity to simply replace abused customers.

 These servers have space for only two internal disks and I'd like to
 try to convert a couple of them into servers of shared storage.
 I'm thinking of just setting them up to sync their disks using DRBD
 and providing access to the rest of the network via iSCSI.

 I'm looking for a way to attach lots of disks to them. So far the only
 options I found are MD1000/3000 from Dell, which are a bit too
 expensive for such a side-project.

 Is there another economical (and sane, speed-wise) way to get lots of
 disks on these system's bus?

 I don't know about Ubuntu, but in Debian these variables are set either in

 changing those is by doing dpkg-reconfigure locales as root.

 Hope this helped.

 All was well, until today. In the last month, on purpose, I've downloaded
 about ~100 GB through Cellcom.
 I've received the invoice yesterday, and starting from today, the bandwidth
 is about ~150 kbps (before it was ~2000 kbps).
 When changing to other Cellcom SIM (belonging to a different number), I
 receive the expected 2000 kbps. When changing to the blacklisted number
 other SIM, I receive the throttled ~150 kbps.
 It's consistent, and doesn't depend on my location.

 In the contract I've signed with them, they're stating that if I'll use P2P
 or more than triple of the network average bandwidth per subscriber, they
 reserve the right to throttle me.

 It's seem that they're doing exactly that. Tomorrow I'll check with
 Cellcom.

 Also, I believe that In the past they've killed DNS queries after starting

Re: Open Source Games or the Lack of Them

2009-09-23 Thread Michael Ben-Nes
For years I been waiting to get the same Windows gaming experience from
Linux.Sadly the gap is just get wider over time and I don't think the
increase will reverse it self in the coming years.

Lucky us technology change rapidly and my expectation is that in the coming
years gaming / application will be streamed to our computer from near
by libraries.
So putting it simply you will have at your disposal the choice of games /
application of every OS. What at least render the lack of games on Linux.
Here is pick to a possible future:
http://www.youtube.com/watch?v=k-w56hQxmnY

As for the Opensource concept, I can only hope that in the coming years
companies will benefit by using the opensource model. That might give them
the ability to harness the community to add extra feature to their games.
There is also the question if the result of this workflow will be better
games ( Sell more ) or like the result of the wiki book ( lame content ).

 Hi all!

 Someone emailed me in private and said that you don't want to mention open

 mention some reasons for why I think this is largely the case.

 Reason: Proprietary Games are OK.
 ---

 If you read Joel on Software's
 http://www.joelonsoftware.com/articles/FiveWorlds.html , you'll see that
 commercial games play by different rules than what Joel calls shrinkwrap
 software, which is software (whether open-source or proprietary) that is
 distributed or used in the wild by many different people. A game must be
 perfectly right the first time, most games are failures, and generally
 games
 require much more effort than just coding the engine.

 Richard M. Stallman was quoted as saying that game engines should be free,
 but approves of the notion that graphics, music, and stories could all be
 separate and treated differently (i.e., Non-Free.):

 http://developers.slashdot.org/article.pl?sid=05/01/09/191257

 Since a typical game nowadays costs a lot of money to develop, and requires
 the collaboration of many people, it seems unlikely that we will see many
 open-source games that are up-to-par with commercial offerings. When we
 work
 on FOSS alternatives to commercial apps: Firefox, Thunderbird,
 OpenOffice.org,
 Inkscape, GIMP, Audacity, etc. we can expect the first versions to have
 some
 bugs and that some features will be missing even in the contemporary
 versions,
 because either they don't matter much to people or because we will
 eventually
 catch up with them. But we cannot afford to do it in most games.

 My hope is that eventually either game engines would indeed be open-source
 or
 at least close (because the amount of work done on the engine is minuscule
 in
 comparison to the rest of the game) so they can be ported to Linux, or that
 at
 least game companies will start supporting Linux better once it gains
 marketshare, or that wine, cedega, etc. will allow better support.

 Reportedly, Blizzard has been using GNU/Linux internally to develop their
 games (World of Warcraft, etc.) and test them, but has not released an
 official version for Linux yet, or supports it.

 Reason: Graphic Artists are unwilling to contribute
 -

 For some reason or another it seems that talented graphic artists do not
 volunteer to contribute to open-source/open-content, whether games or other
 software. You can see some discussion of it here:


 http://www.shlomifish.org/humour/fortunes/shlomif.html#third-sharp-perl-reich

 And scrottie later continued it in this blog comment to a post where a
 graphic designer expresses moral outrage at being asked by Google to
 contribute design work to Chrome in exchange for thanks, not money

 http://use.perl.org/~scrottie/journal/38916

 While there are probably fewer professional graphic artists than
 professional
 programmers (since many classes of programs require very little graphics
 design), I still think that a much smaller percentage of them contribute to
 open-source than programmers.

 I don't know which percentage of programmers contribute to FOSS on their
 free
 time, and there was something that people asked after the 2001-2002
 recession,
 when many programmers became unemployed, why we don't see a flood of
 Israeli
 programmers to FOSS projects, where they can gain some esteem, experience,
 knowledge, and also have something to do in their free time. Nevertheless,
 there are still enough programmers to make a difference and to even pose a
 significant competition to commercial offering.

 I don't know the reason why graphics artists are so reluctant to

 The problem I have is that Drupal 6 is not packaged for 8.04.  I got around
 this by installing Drupal 6.10 from Ubuntu 9.04, but even this has pending
 security updates.  So I'm considering updating to the version from the

 But this raises a problem.  It's possible to update Drupal from within

 to provide a Drupal installation or should I just install the main upstream
 package asis and use its own updating capabilities to keep it updated?

 I can see complications ahead if I don't make a firm decision one way or
 the other, so I'd like the advice of anyone who has had to deal with this
 sort of thing.

 I don't know much about Drupal and I don't particularly plan to.  I've been
 asked to install it so that content people can do their thing with it, and
 that people in charge of specific sites on the machine can admin their bit
 of it.  Am I naive in thinking I can keep my distance from this?

 I encounter several issues in how to get them to use IRC.

 One of them is that they don't find the IRC clients intuitive for them.

 The other one is that they seem to be afraid of talking on the main
 project channels. I know it is difficult to wonder in a room full of people
 and start talking. It is difficult if the channel is silent and it is
 difficult
 if people are already talking. The newcommer can feel that
 s/he is making noise or interrupting the conversation.

 So I was wondering how to try to solve this?

 We have our own channel for the project where they started to talk
 a bit. That's a good step. I was wondering if we should setup a

 #projectname_babytalk or #projectname_kindergarten or #projectname_newbies
 channel in the hope that people can start talking there first?
 If so what name would you suggest?

 What other strategies do you suggest?

Re: Virtualization recommendation

2009-09-15 Thread Michael Ben-Nes
If your primary OS is the Linux one, then I recommend installing it as a
host and use VirtualBox ( basically because its so easy to use )
If you intend to play 3D games on win7 then note that it wont work on a
vitalized OS. In my case I just created a separated portion just for win7 /
games.

As for the Vista, throw it away and install win7, no reason to waste future
time on upgrade. Win7 work so much better then Vista as a host and as an
guest.

Re: Which is the best ISP in Israel when accessing US server using ssh

2007-10-21 Thread Michael Ben-Nes
Yep, in the resnable time effort.

1. Israeli ISPs shift traffic over lines from time to time, due to their
notorious tendency to buy STM1 links, due to them being cheaper (a STM4
takes time to fill, and while it's not full, they waste money). Thus, their
STM-1s get filled up quickly, and they shift traffic based on alot of
variables, depends on what you've bought, the kind of traffic you pass
through, etc.

Talked with the ISPs getting nothing. They ask for traceroute ( with the
hope I wont return ) and then do nothing but bla bla bla. Its cheaper to buy
a satellite or lay my own cable to the US then waste eon with the ISPs :)

2. There are four virtual segments to check.
 a. One is your local loop (meaning the connection from your office to the
ISP, and I include in this the connection inside you office).

No problem here. I have fast access to other locations

 b. Two is the connectivity of the edge router that you connect to on the
ISP side to the ISP internal core network.

Checked what I could with and without the ISP ( refer to my answer to point
1 )

c. The international connectivity of the ISP in regards to the IP block
which you are part of, since they don't advertise all IP blocks equally,
including possible QoS tagging they may do, or other traffic shaping.

I assume the problem is here.

d. The local loop of the ISP you want to get, including the connectivity in
the LAN of the hosting place, or company.

Thats probably ok because I get good responses from other directions ( like
with the tunnel )

Conclusions? not clear ones. I assume the ISPs are less generous to ADSL
users then server hosters when it comes to international lines.

Which is the best ISP in Israel when accessing US server using ssh

2007-10-15 Thread Michael Ben-Nes
Hi,

I'm working on a project that require me to ssh to a US server.
The problem is that through Netvision  Bezeqint the performance are
horrible ( though Bezeqint its almost always faster then Netvision )

I don't mind paying double for a better connection. Waiting 10 sec to see
something happens over ssh is too much.

The IP of the server is 216.139.210.179 and its located at HostWay data
center in Texas.

Any recommendations?

Best,

You should have some relevant lines in your /etc/apt/sources.list,

deb http://mirror.hamakor.org.il/pub/mirrors/debian sid main contrib
You might want sarge instead of sid for the stable version.

Then do 'apt-get update' to update apt's indexes, then 'apt-get install

Re: RAM swap

2006-02-16 Thread Michael Ben-Nes



Tzahi Fadida wrote:


Note that postgreSQL has a local swap of itself for doing big sorts etc...

However, I have a feeling its more to do with how much time it takes for
your transaction to finish. There is an automatic mechanism in postgreSQL
that drops the connection if it thinks the transaction got stuck.
I usually thinks that if in a specific command in a the plan tree the executor 
cant
advance past a sub plan around 15min which is usually impossible(I think) unless
you write your own functions like me.
  
I don't think so because to my understanding the kill came outside 
PostgreSQL ( kernel ? )

I also noticed the process worked more time after increasing shared_buffers.

Note that in postgreSQL functions can only return all their result 
(materializing)
even if it seems like pipping it is not(it was not implemented yet), so all the 
P lang, J lang,
etc... can get stuck.
  

No functions at all :) only plain SQL

Perhaps you can increase the time out, however, try first to drop the indices
in your tables (+unique constrains which are really indices) and build them
at the end.
  

Yes, we did that. or the process could take even more time.
We also used prepare to accelerate the insert process

besides that, as you already said, you need a bigger swap. (9GB worth :)
  

But thats the strange thing. the swap never get used.

Finally, this could also be a bug in postgreSQL though I doubt it.
If you write C functions like me (like a second postgreSQL in a function), 
memory leaks are common :). So check your functions.

RAM swap

2006-02-07 Thread Michael Ben-Nes

Hi Everyone


I don't get this RAM / swap relation.


I have a script that feed data into PostgreSQL database.

All the data is fed as one huge transaction that takes allot of memory.


I noticed that one 1GB RAM machine the task cant be completed ( kernel 
kill the process ) while on 3GB RAM it can.


The strange thing is that on the 1GB RAM machine the swap is not used at 
all.



I thought that when the RAM is fully used the OS start to fill up the swap.

I'm obviously wrong :)


Can any one explain this topic ?


Thanks

Miki

But then i wont be able to control who has what. and the access will be 
limited to a device or a desktop.



Think of a system where i can:
Add new password and enable USER1, USER2, USERn to access it ( i assume 
the passwords will be save using appropriate pgp key, maybe the user key )

On change all relevant fields will be updated.

Is it possible that I'm the first one who need such an option ?

What you're looking for is a password wallet solution.
KDE has kwallet my OSX has a keychain manager and I'm sure gnome has

There are also physical devices to store stuff like that from toys at

I'm sure that if you're phone has java app support you can find a

Hi, 


I am an old time ELM user, now upgraded to MUTT. I have over 4,000 email
files (each containing multiple emails) in my Mail directory. This is
because I've been collecting emails since 1991 and want to keep them
online so I can refer to them.

However I would like to join the rest of the world and use a web based email
client. 


The problems that I have are:

1. It needs to be able to access them email in the mutt files interchangeably.

2. It needs to work on a web server running Apache 2.

3. If it uses IMAP, it needs to have support for SSL.

I tried roundcube and found that it has two problems that affect me:

a. It does not see my old email files. This could be an IMAP problem
  or another problem. I turned off email caching in roundcube to prevent
  double copies of the files.

b. If I go into folder list on on roundcube, it crashes due to using too
  much cpu time. I have a slow computer, but 128 seconds is a long time.

Anyone have an suggestions for other software?

performance diffrence between two servers

2005-09-29 Thread Michael Ben-Nes

Hi Everyone


I transfered a perl script driven web site ( not mod-perl ) to a new server.

On the old server the performance where quite good and on the new one 
they sucks big time.



Old Server is:

CPU: Intel(R) Pentium(R) 4 CPU 2.00GHz with 512KB cache

MEM: 1GB DDR ( i think 200mhz )

DISKS: HW SCSI RAID ( mirror ) U160 10K RPM

OS: Red-Hat 7.3, Kernel 2.4.19


New Server is:

CPU: AMD Sempron(tm) 2800+ with 256KB cache

MEM: 1GB DDR 400mhz

DISKS: Software RAID 1 from two IDE 7600 RPM

OS: Debian Sarge, Kernel 2.6.8-2-k7


What happen actuly is that apache on the new server cant handle the cgi 
script ( perl ) like it did on the old server.


iostat, top  dstat show that the CPU (usr) is under heavy load ( 
97-100% ). there is no wait and sys take around 1-3%.



Its not the Disks as i made few tests that where successful ( under load 
) and the respond was very fast.


I also find it hard to believe that 2-3 year old 2GHZ Pentium is way 
stronger then AMD 2GHZ ( 2.8 ).



Any ideas ?

Re: performance diffrence between two servers

2005-09-29 Thread Michael Ben-Nes

But the the CPU user was not on 100% but on 40%  the wait as on 60%

I was also able to duplicate a file ( 700mb ) quite fast under the load. 
this prooved me that the disks are not the issue.



Unless the software raid is very hungry when it comes to kernel 
calculation ? though i would expect the over head to be shown under CPU 
system and CPU user.



Am i right ?

I beg to differ. The single biggest difference between the two
servers is:
 


DISKS: HW SCSI RAID ( mirror ) U160 10K RPM
   


Versus
 


DISKS: Software RAID 1 from two IDE 7600 RPM
   



They are simply not in the same league. Try running
hdparm(8) and check the results.

Re: sys / db performance block size

2005-09-14 Thread Michael Ben-Nes

After a week of testing i decided to go with JFS as the FS for Postgres.
im not an expert benchmarker so I hope I initiated the right parameters 
in bonnie  pgbench.


The bonnie command:
bonnie++ -u miki -b -d /data/bonnie/ -s 6080:8k -m pr1

pgbench commands:

pgbench -i -s 10 test
pgbench -c 10 -v test
pgbench -c 10 -t 1000 -v test

Any way here are the results of bonnie++  pgbench:

http://www.canaan.co.il/users/miki/stats/stats.html

I couldnt create a filesystem with block size of 8k because my page size 
is 4k.
Is there a way to extend the pagesize to 8k ? ( i mean without compiling 
the kernel ).

at both levels might defeat the database's disk-access atomicity.

(And before I'll be suspected of bias - I use ReiserFS for my home machine

Re: sys / db performance block size

2005-09-06 Thread Michael Ben-Nes
After few test, not certain yet i found *Surprise*Surprise* ext3 is 
quite fast especially when using dir_index


This is the command i issued. i was recommended going on Journal size of 
400 ( not really sure why ).


mke2fs -j -J size=400 -O dir_index -T largefile /dev/sdb1


testing it with bonnie++ brought back better result then Reiserfs.


Seems like IBM ServeRAID family not support 2.6 and are close source.

I suspect my performance under Centos 4.1 could be much better.

Someone advised me to go on software raid as the scsi drivers are much 
more supported. Any idea ? ( ServeRaid 6i IBM x345 )



Will report back later.

I am guessing that Debian did not invent this country, but rather that

A simple Google search confirmed my guess: see, for example,
http://lists.debian.org/debian-boot/2004/04/msg00231.html

Other search results show what can happen when they broke the cover your

Debian Political standings

2005-08-11 Thread Michael Ben-Nes

Hi Everyone

While installing Debian i was asked to choose from which coutry I am.
I was suprised that in the country list I found the following entry:
Palestinian territories, Occupied

Its not that importent but:
1. Does debian need to take a stand in the dispute ?
2. Even if they choose to show the Palestinian territories why they 
added the Occupied?
3. if point 2 is accepteble why they didnt added Iraq, Occupied or 
Basque, Occupied  or maybe if they really want to state opinions how 
about North Korea, death camps?


Considering the fact that the Palestinian state never existed we can 
conclude that someone use Debian to say false accusations.


I think that the Israeli Community should ask to correct that.

I also must clear that I dont take a political stand ( in the list ) for 
or against the Palestinian or their right for a home land.


Cheers

Yep, having an exact _current_ copy all the time on two storage system.
Its the WAL ( Write ahead log ) of the postgresql DB.

So i assume it will be quite Long and will change every sec or less.
I would like to keep the backup on a another computer. NFS and such.


does it mean: having an exact _current_ copy all the time on two storage

does it mean: keep a historic change log of the file for every change
made, with the ability to rollback to any desired state?

does it mean: keep a backup of the file every 10 minutes?

does it mean something else?

then define: the size of the file (min/average/max)
the rate of changes per time unit (min/average)
who generates the file and changes to the file - a given
software you wrote, a given software you did not write?
are the changes to the file performed manually, or by
automatic software?

then come back.

Re: Advice - fastest INTEGER operations CPU

2005-08-07 Thread Michael Ben-Nes
Read somewhere today ( wish i remembered where ) that if the budget is 
limited and the option are:



Dual Opteron 250 CPU

OR

One CPU 275 ( dual core )


You should go on the single 275.


one of the reasons was the balancing between two real cpus slow the 
performance.



Im wondering if that true.



Gilboa Davara wrote:


Shachar,

There's no single answer to your question; in-order to give you better 
answer I'll need some further information about your software.
Here's a couple of points that you might find interesting: (I mostly 
do kernel-level network streaming/filtering work, so YMMV)


* The AMD Opteron *is* the King of the Hill. I found that my HP 385 
(Opteron 248/250) and older IBM e326 (Opteron 246/248) to be able to 
outperform a similarly configured (and priced) Xeon 2.8/3.4/3.6 (DL 
380, IBM e345) hands down. Highly memory and I/O intensive 
applications like my own (which spends days btree searching and 
memXXX-ing itself to death) seem to *greatly* favor the Opteron's 
on-die memory controller. (compared to the Xeon's traditional 
north-bridge design). I'm still looking for ways to use the Opteron 
NUMA support; I *assume* that xxx_alloc_node will further improve 
performance.


* The dual core option is a true winner. Even the relatively cheap 
(?!?!) Opteron 265 machine can run circles around a quad Xeon MP 
machine. (Shared bus designed never really favored  2 CPU 
configuration.) At less then 1000$ per 265 CPU, building a dual - dual 
core workstation / server is pretty inexpensive. (I plan on upgrading 
my private dual Opteron workstation to dual core once I find someone 
that's willing to buy my left kidney...)


* The GCC's x86-64 AMD64 optimization favor the Opteron greatly. Only 
when we optimized our code with -march=nocona we managed to level the 
playing field a *bit*. Somehow Intel seem to  have skimped a little 
when it they duplicated the AMD64 (s/EM64T/AMD64/g)
As far as I remember the Debian AMD64 port is using -march=nocona to 
help the Xeon save face. (Same goes for my FC4/x86-64 machines)


* The Xeon might close the gap if you have highly hyper-theadable code 
(little or no I/O [including memory I/O] with a lot of integer 
calculations). In such a (remote?) case, you might actually see a 
10-15% gain per socket, maybe even slightly outperforming the Opteron. 
However, if you plan on using more then two sockets (dual), a shared 
400/533Mhz bus doesn't play nice with Hyper-threading enabled. In 
general I'd stir clear of Hyperthreading on dual - or -above machines.


* Might sound weird... but while working on my previous project we saw 
instances where an older 2.8Ghz 533Mhz (Prestonia?) Xeon was able to 
outperform the 3.0Ghz 800Mhz Nocona Xeons. Go figure.


* The Itanium (1.4Ghz, Medison core?) has lousy Integer performance 
and memory performance. Don't touch it. (Or you'll burn... literally...)


In general I find the Opteron to be the superior platform. But again, 
we conducted out tests with our software, so YMMV (greatly).


Hope it helps,
Gilboa

Hi all,

I'm looking into buying a computation server for a client. They are 
looking for the platform that will give them optimal INTEGER 
performance. I'm thinking between the 64Bits - PowerPC, Itanium and the

knowledge (Xeon is better than Athelon etc.).


Thoughts? Ideas?

Any solution picked will be running Debian Linux (Sarge), and the

Re: Apache access problem

2005-07-31 Thread Michael Ben-Nes

quite easy: write the error in google and walla:


snip from a thread:


Whew. I found the reason for the problem. Apache is running as
group www and the group file had two groups www with different
numerical ids. Must have some historical reason that we use a
differing numerical id on a few machines. One of the updates
must have either readded the old offending id or changed the
way the id is grabbed on daemon startup, so most of the time the
wrong numerical id was grabbed, clashing with the numerical id
in the file system.

web page to see how this worked. At the time, I had no real problems. Today, 
I tried to access that page and got a 403 error. 


Here's what I've tried so far.

1 - I looked for error messages and found the following 
in /var/log/httpsd/error_log:

2 - I then tried apachectl (as root) and got:
[EMAIL PROTECTED] solomon]# apachectl extendedstatus
  Forbidden

  You don't have permission to access /server-status on this server.

  Apache Server Status for shlomo1.solomon

3 - the following was in /var/log/httpsd/error_log:

access to /server-status failed because search permissions are missing on a 
component of the path


4 - I GOOGLED and learned it's a probably a permission problem. 

According to http://www.onlamp.com/pub/a/apache/2004/04/22/apacheckbk.html:  


quote
What search permissions are missing on a component of the path means is that 
somewhere in the directory path leading up to the file in question, there's a 
search (x) bit missing from one of the directories. You see, Apache needs to 
be able to look at files, the same as any other application does. And so it 
needs the search bit (x) set so that it can cd into a directory to get a look 
around.


For directories containing the web content, you need the read and execute 
permissions to be set. For a directory that Apache will just need to pass 
through on the way to a content directory, execute (search) permission is 
sufficient.

/quote

But, as far as I can see, my permissions are set OK. 


The page is in the standard location as set up by the Apache installation:
[EMAIL PROTECTED] solomon]$ ls -la /var/www/html/index*
-rw-rw-r--  1 root root 1299 Jul 30 21:15 /var/www/html/index.shtml

favicon.ico is in the same location:
[EMAIL PROTECTED] solomon]$ ls -la /var/www/html/fav*
-rw-r--r--  1 root root 1406 Aug 26  2004 /var/www/html/favicon.ico


And here are the permissions of all the directories in the path:
[EMAIL PROTECTED] solomon]$ ls -lad /var/www/html
drwxr-xr-x  15 apache apache 720 Jul 31 00:07 /var/www/html/
[EMAIL PROTECTED] solomon]$ ls -lad /var/www
drwxr-xr-x  11 apache apache 272 Jan 23  2005 /var/www/
[EMAIL PROTECTED] solomon]$ ls -lad /var
drwxr-xr-x  27 root root 680 Jan 31 20:09 /var/


Any ideas what's wrong here?

TIA

DMZ public IPs and such

2005-06-14 Thread Michael Ben-Nes

Hi Everyone


I installed IPCOP with RED/GREEN/ORANGE (dmz ) legs.

The DMZ use internal address of 192.168.1.x

On the DMZ i have a mail server and a web server
Currently i cant telnet port 25 from the webserver to the real public IP 
of the mail server.


I been told on IPCOP list to resolv the internal address and not the 
public one. but this will double the admin work with domains.


sound me quite logic to route incoming internal packet whos destination 
is the public IP to the correct internal.


Am I right ?

ns1.some-domain.com

I dont think it will be wise to set the DNS servers within the same

What is the best practice ?

There is no problem in having the domain nameservers reside under the
domain itself, as long as those domain servers are directly pointed to
by the delegating registrar.

Why?

Because when a DNS cache does a query about a domain it doesn't know
(your domain), it goes to the root (.) and asks it for the TLD's
authoritative nameserver. Then, it asks the TLD's authoritative
nameserver about your domain. The TLD's authoritative nameserver replies
with the list of nameservers you supplied to the registrar; If those
nameservers are within your domain, it'll also send _in_the_same_reply_
the IP addresses of these nameservers; No loop.

Example:

[EMAIL PROTECTED] ~ $ dig @a.gtld-servers.net google.com

;  DiG 9.2.5  @a.gtld-servers.net google.com
; (2 servers found)
;; global options:  printcmd

Your system clock is still two months behind...
 


Sorry. Fixed. its not my work station :)


No, I said that when YOU define a nameserver for a domain that resides
under the same domain, YOU also give the IP address of this nameserver,
and the DNS server delegating the domain to YOU will provide that IP
information you gave when it's queried about the nameservers of YOUR
domain.
 

might do an extra work when changing IPs. I think ill just ask Netvision 
to be my slave servers for the Server domain.



Sounds a bit complicated, but to conclude: it simply works if you
provide a NS hostname and IP address in the registrar. ;-)

ppmtogif or ppmtojpeg will convert ppm to gif or jpeg, resp.  (in RedHat

the software one is irrelevant. Is it true ? ( assuming im using simple 
2 HD mirror )

Is it possible to Hot Swap the faulty HD in the software solution ? the 
IBM spec say the bay  scsi adapter support hotswap.

How reliable and easy to maintain is the software solution ?
and one last bomb :) what is more Linux friendly IBM or Dell ?
Thanks

i.e. Hard Disk scsi 200GB x 3 because is RAID.
Maybe we can ask some companies to donate.

Hello to both lists,
This mail is to let you know a bit what's going on with the mirror.
In three words: Disk Space Shortage.
Where did all the disk space (~125 GB) go?
The three big mirrors (Debian, Gentoo, Mandrake) grow each day, and
filling up the FS almost every day.
The following mirrors were removed to free some space:
* Fedora Core ISO files
* Gentoo 2005.0 for amd64
* TheOpenCD mirror
* MandrakeMove ISO files
But I'm still in space shortage. So the next victims are:
* cygwin mirror
* debian non-us
* mandrake cooker

Xeon, 64bit Debian

2005-03-08 Thread Michael Ben-Nes
Hi All
In the previous thread i had I/O problems with IBM machine with 2 Xeon 
3G Cpu, 3 GB Mem and Raid.

The solution ( upgrading the Raid card capabilities ) require me to 
reinstall the OS on the mechine.

Naturly I thought about Debian Sarge :). The New Xeons support 64bit and 
i thought installing the 64bit version.

Is it worth it ? im going to run postgres on it.
Also i could not found the right package under:
http://www.debian.org/devel/debian-installer/
Which package is it ?

If you need a good raid they attach piece of hardware to the scsi card

I'm going to raise some questions in order to trigger you for the fault.
Are you sure that its not a hard disk bound queries?
Mybe the raid is slower then the last. (faulty driver??)
Seems so though not suppose to. its LSI Logic 53c1030 Fusion-MPT Dual 
Ultra320 SCSI.
The formaer one is Adaptec 2015 which suppose to be slower.

I suspect the Raid is the problem, some how its not fast as i expected 
it to be. im going to throw the Centos away and install a beautiful 
Debian Sarge 2.6.x on it :)

Is the os the same or you swiched it?
If you swiched it, i guess you have a problem with the kernel, mybe a module 
or something. Try to google for xeon slowing and the kernel.

Did you swich filesystem?
Yes, the OS came with ext3 :( thugh i dont think it can take the mechine 
down. maybe 10% in performance.

Re: Linux, Raid and how do I know the speed

2005-01-04 Thread Michael Ben-Nes
Very strange, i get the CPU stats but the device stats are blank.
Tried on few systems, checked google but couldnt find the reason why its 
not shown.

some of the tests:
iostat -x hda2 5
iostat -x /dev/hda2 5
iostat -x hda 5
iostat -x 5
and so on.
im using Debian woody  kernel 2.6.x
tried both on IDE system and SCSI system
Any idea ?

You could use measurement tools, for example:
dd if=/dev/sda of=/dev/null
and in the meanwhile, measure the speed using iostat:
iostat -x /dev/sda -kt 5
(-x device -Kilobyte -refresh every 5 seconds)
The stats in /proc show what's the bus speed, which is nice, but not 
very usefull (you know your max speed).
