On Myths ..

This is a rant about 'common knowledge' and about how it hurts technology. You would think that what I'm talking here are wiki's...well.. maybe a bit. Wiki's posess one truly great ?thing? going on for them - they're not authoritary sources and it's very easy to correct them. And most importantly - you're generally encouraged to fix wiki articles. This results in very interesting pattern - often you'll find wiki article that describes something in great detail... and then goes on debunking previous claims by prividing correct definitions PLUS reasons for the not-totally-correct explanation that prevails. There is very well known and recurring pattern out there, small fact, like '2.4.x kernels won't compile with 3.x gcc', they are repeated few times by those that tested this, then the whole 'clergy' learns it by heart ( those that have no idea what they're talking about, but repeat what they heard/read from their 'guru'). By repeating their mantra, they enter 'inner circle' of their religion, they feel superior to the uninitiated, closer to their 'gods' etc... This are all well known ...

how about - squid configured with null cache, using only some memory, and oops attached to it as parent?

Generic Scheduler - Design Patterns

As I'm slowly getting older, I encounter recurring problems , with perl and general practices being already decades old, one would think that there are well-tested and generic solutions.

One of those thingies is problem of generic hmm, message-scheduler or maybe switch.

You can see this in projects like alamin (sms gateway), varios MTAs, B2B solutions sending invoices, SNMP managent consoles etc..

One way of solving that is by using filesystem - aka spool directory.

Popular solution - shared space aka spool, multiple daemons handling messages - incoming, outgoing, processing...

Two mains choices - spool directory and sql table.

Requirements for spool:

Ability to drop incoming message into it
Ability to check emptiness of spool/list waiting msgs
atomic operation for changing status of msgs ( processing, finished )

Proponuje na poludnie od Lublina, np. Zemborzycka do Prawidniek, dalej
do Osmolic i wzdluz Bystrzycy spokojna szosa w strone Zakrzowka (unikac
piwa w knajpce na rozdrozu, nie najdaje sie do picia) i dalej ku
Roztoczu. W okolicach Batorza, Blizowa (tu juz dostepne znakomite
lokalne janowskie piwo, warzone wg tradycyjnej receptury) mozna jechac
przez Wole Galezowska w kierunku Bychawy, a stamtad przez Bychawke
lokalna, wlasnie odnowiona na dluzszym odcinku szosa po lewej stronie
rzeki do osmolic. Z Osmolic przez Kreznice do Lublina.
Te trase mozna zrobic tez jadac za Zakrzowkiem do Modliborzyc. Ciekawe
sa tez trasy w kierunku Wisly, czyli na zachod, ew. pd-zach.
Mapa w garsc i do dziela!

Ja bym poleca³ trasê do Krzczonowa, czyli Krzczonowskiego parku
krajobrazowego. Zeby wysz³o 100km trzeba objechaæ kawa³ek tego parku, a nie
tylko dojechaæ do tablicy z napisem "Park krajobrazowy. Mo¿na zawracaæ:)"
Generalnie mo¿na pojechaæ w stronê zalewu i pojechaæ w stronê Prawiednik,
min±æ i jechaæ w stronê ¯abiej Woli. Potem skrêciæ w lewo najbli¿sz± wieksz±
poln± drog±. Potem przez pola t± drog± mo¿na fajnie wyjechaæ a¿ do trasy
Lublin - Czerniejów - Jab³onna - Piotrków i gdzie¶ ko³o Piotrkowa skrêciæ w
lewo, potem lokalnymi asfaltami kierowaæ siê w stronê masztu Radia Puls,
mieszkañcy okolic na pewno pomog± znale¼æ. Dalej ca³y czas prosto a¿ do
skrzy¿owania w jakiej¶ wsi. Tutaj w lokalnym geesie znajduje siê bardzo mi³a
pani, która sprzedaje bardzo dobre lody w przystêpnej cenie nawet w niedzielê
po po³udniu. Na tym skrzy¿owaniu odbija siê w prawo na Krzczonów (jest
tablica) i jedzie pro¶ciutko, pro¶ciutko a¿ do tablicy "Park Krajobrazowy".
Do tego miejsca jest oko³o 35 km, wiêc ¿eby by³o 100 km warto poje¼dziæ
troche po okolicy.

BSD - Bastard patcheset for Linux kernel. 2.4.26-bsd21k

Wed Jun 2 20:37:54 CEST 2004 21k is now ready/in testing https://ghost.anime.pl/~eyck/Projects/bsd/21k/, contains

FRESH: it now compiles with gcc 3.4.0
FRESH: it now compiles with gcc 3.3.3
FRESH: contains gcc 3.4.0 compilation fixes from Rock Linux, plus few personal tweaks (drbd, honeynet logging etc...) (btw, drbd is still 0.6.1, while current is 0.6.12, I'm not using drbd in production so it may take me some more time before I get to updating this)
UPDATE: ocfs updated to 0.1.9
jfs deadlock fixed: http://linux.bkbits.net:8080/linux-2.4/cset@1.1359.20.3
rfc2385 - md5 protection on long-running tcp sessions
Bunch of fixes from http://www.csd.uu.se/~mikpe/linux/patches
UPDATE: openswan updated to 1.0.4

Plus new stuff from earlier non-released bsd21XXXs:

UPDATE: squashfs 2.0 ( GREAT STUFF! )
FRESH: esfq 2.0
FRESH: ext2 compression ( chattr +c ) (this is not for production, will be removed in stable branch)

This time around I'll probably release debian kernel packages compiles with gcc : 2.95, 3.3.3, 3.4.0 with and without space-conserving optimisations (-Os)

NOTE: -Os brakes stuff, for example, usbcore no longer works

	unresolved symbol memcmp

with 3.4.0 I still have those problems:

/lib/modules/2.4.26-bsd21k/kernel/fs/ocfs/ocfs.o: /lib/modules/2.4.26-bsd21k/kernel/fs/ocfs/ocfs.o: unresolved symbol ocfs_version
/lib/modules/2.4.26-bsd21k/kernel/net/khttpd/khttpd.o: /lib/modules/2.4.26-bsd21k/kernel/net/khttpd/khttpd.o: unresolved symbol tcp_v4_md5_lookup

To be investigated...

Scotty Doesn't Know Lyrics


Artist: Lustra Lyrics
Song: 
Scotty Doesn't Know Lyrics

Scotty doesn't know that Fiona and me 
Do it in my van every Sunday.
She tells him she's in church but she doesn't go
Still she's on her knees and Scotty doesn't know!

Oh Scotty doesn't know!
So Don't Tell Scotty!
Scotty doesn't know!
Scotty doesn't know!
So Don't Tell Scotty!

Fiona says she's out shopping,
But she's under me 
and I'm not stopping...

Because Scotty doesn't know!
Scotty doesn't know! (X3)
So don't tell Scooty!
Scotty doesn't know!

I can't believe he's so trusting,
While I'm right behind you thrusting.
Fiona's got him on the phone,
And she's trying not to moan.
It's a three-way call and he knows nothing! nothing...

Scotty doesn't know!(X3)
So don't tell Scotty!
because Scotty doesn't know!
(Scotty doesn't know!X2)

We'll put on a show!
Everyone will go!
Scotty doesn't know!
Scotty doesn't know!

the parking lot?
Why not? It's so fun when you're on top!
It's full on in the snow
If it's a hunk(?) because Scotty doesn't know!

We did it on his birthday...

Scotty doesn't know!(X4)

Scotty doesn't know!
Scotty won't know!
Scotty doesn't know!
Scotty's gotta know!
Gotta tell Scotty!
Gotta tell him myself!
Scotty doesn't know! (X10)


[Chant] Scotty doesn't know! 
[Chant] Scotty's gotta go!

Why XFS

Motto: quoting xfs whitepaper from 1996 usenix conference: With today's 9 gigabyte disk drives it only takes 112 disk drives to surpass 1 terabyte of storage capacity (emphasis mine). http://oss.sgi.com/projects/xfs/papers/xfs_usenix/index.html

XFS: eXtended File System (SGI, Unix, Windows)

What are 'journaled filesystems': filesystems with journal.

Old and very well-tested: shipping since 1994
Very good performance on large IOS
Fully 64bit filesystem, has no problem with large files and discs, very well tested ( literaly decades ) with terabyte-range files and filesystems.
Security: damaged files gets zeroed...
Native quota
Native acl
Native EAs

Relatively new to linux. But still - oldest journaling filesystem available on Linux
Slow on small files ( with 1-2k sized files even ext2 is way faster)
Convenience: damaged files gets zeroed... supposedly this is the issue with all journaling filesystems
Not very popular - issues with exotic software: quotes inside virtual servers, etc..
Not very simple codebase, stable and well-tested, but very big and relatively intrusive. (non-issue on 2.6, where lots of needed support was moved to lower layers, things like variable-size IO requests, delayed allocation )
Takes few % more of diskspace then others, it bit me when I tried to convert partition that was 99% full...
On related note - xfs is very slow when filesystem is 99.x% full,
No data=journal
You can't use it in raid1 both driectly on hardware and via md1

Devices needed for vserver operation

/dev/random ( needed for crypto, supposedly is safe to put inside vservers, because it can't be used to brake random pool, ie - you can update pool, but not in a way that could harm entrophy or sth..) /dev/tty ( used by lots of perly stuff and more ) /dev/null ( some stuff needs it, especially sh scripts )

BSD - Bastard patcheset for Linux kernel. 2.4.26-bsd21c

Wed Apr 14 21:42:00 CEST 2004 Todays release (21c), https://ghost.anime.pl/~eyck/Projects/bsd/21c/, is based on recently released 2.4.26 contains

Tiny patch fixing this:

 
 In file included from gamma_drv.c:34:
 drmP.h:180: redefinition of `__cmpxchg'
 /home/eyck/bsd/patches/21b/work/linux-2.4.26/include/asm/system.h:245: `__cmpxchg' previously defined here
 make[4]: *** [gamma_drv.o] Error 1
 make[4]: Leaving directory `/home/eyck/bsd/patches/21b/work/linux-2.4.26/drivers/char/drm

vserver routing fixing patch from Herbert of Vserver fame
floppy-fallback patch from Herbert of Vserver fame
drbd returns to tree, relativly old version..

Also, together with patchset I prepare 'default' kernel, which configuration is based on debian kernels. This time around I added strangely missing pcmcia-support, and enabled advanced routing ( multipath ... )..

Filesystem for squid.

For xfs, try this:

/dev/hde3 on /var/spool type xfs (rw,noexec,nosuid,noatime,osyncisdsync)

But supposedly the best fs for squid is reiserfs, and you may like those options:

reiserfs (rw,noexec,nosuid,nodev,noatime,nodiratime,notail,block-allocator=noborder)

Nice thing to remember is that squid is very HDD intensive application, so it's rather unwise to run in on anything slower then SCSI (like you can see above I'm running it ;) is asking for trouble... and dumb.

You should also consider oops instead of squid for following reasons:

oops is more lightweight then squid
it's way easier to set up and configure.
oopsctl stat provides hot stats in nice format
oops can use raw partitions as it's cache.
oops very quick to stop and start. ( try /etc/init.d/oops restart -> few seconds, try /etc/init.d/squid restart -> few minutes ). And you don't wan't your users waiting for few minutes when you change something simple but requiring restart.
oops provides special for for transparent proxy ( with squid you can use either transproxy programm, or configure your squid as transproxy, but if you do, prepare for troubles when you use it also as normal proxy)
squid is rather old code, oops is young and developing vigorously. It's code is cleaner and smaller ( squid is well tested, but contains lots and lots of cruft accumulated for years).
oops uses single file as it's spool, not some clunky array of arrays of directories. Way easier to manage.

Update:

Based on: http://conferences.oreillynet.com/presentations/os2002/wessels_duane.ppt best filesystem for squid cache is ext2fs, and worst is xfs ( no wonder... ). second best filesystem for squid seems to be reiserfs (notail,noatime), but ext2 is twice as fast as reiserfs in this scenario.

17f includes Jan Dubiec's newest mppe/mppc module. Unfortunatelly it contains fix for 'PFC bug', which, unless you're affected by 'PFC bug', triggers 'PFC bug'. 17g will be available with older (0.98) version of this module

netconsole patch should not be trusted. As Herbert Poezl says:

11:51 < Bertl> eyck: it seems that some parts of the netpoll api ahve sneaked in for the following cards:
11:52 < Bertl> net/8139cp.c, net/b44.c, e1000/e1000, net/gt64240eth.c, net/mv64340, net/tg3.c

thus, you should be cautious with using this feature on those cards.

Things missing from vserver... or sth like that

mount -o bind,ro http://vserver.13thfloor.at/Experimental/patch-2.4.25-rc3-vs1.26-bme0.04.diff
near-instantenious creation of vservers
single configuration for zone - what devices it needs, what directories to import, comment ..
IPv6 support
Some types of filesystems should be mountable inside vservers... some shouldn't. There's someone doing work on something similiar in 2.6.x tree ( user-mountable filesystems )
Extended auditing inside zones
'privilege' set
well-thought ability to use raw devices inside vserver (?)

Zones in Solaris10

TODO: prepare similiar tools for vserver, From: John Beck Newsgroups: comp.unix.solaris Subject: Introducing Solaris Zones Date: Wed, 25 Feb 2004 22:23:34 +0000 (UTC) Organization: Sun.Software.Solaris Lines: 173 Message-ID: NNTP-Posting-Host: opal.sfbay.sun.com Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Trace: news1nwk.SFbay.Sun.COM 1077747814 2188 129.146.86.88 (25 Feb 2004 22:23:34 GMT) X-Complaints-To: usenet@news1nwk.sfbay.sun.com NNTP-Posting-Date: Wed, 25 Feb 2004 22:23:34 +0000 (UTC) X-Mailer: exmh version 2.6.3 04/04/2003 with nmh-1.0.3 Hello world, Solaris Express 02/04 is now available, and this post is to announce one of the exciting new features, a means of partitioning a single Solaris instance into isolated application environments called "zones." (Note that Zones and Resource Management are related subsets of "N1 Grid Containers"; N1GC = S10RM + Zones.) Each zone can be separately administered and each zone can run an independent set of applications. Zones allow one or more processes to run in isolation from other activity on the system. Processes running in a given zone cannot monitor or affect processes running in other zones. For example, a process running in a zone will only be able to send signals to other processes in the same zone, regardless of user id and other credential information. Likewise, processes in zones will be unable to control global aspects of the system configuration such as run level, most physical devices, and network routing tables. (The exception is the global zone, which is discussed under Security, below.) Features: * Security Network services can be run in a zone, limiting the potential damage in the event of a security violation. No process running within a zone, even one with superuser credentials, is allowed to affect activity in other zones. Certain activities, such as rebooting or shutting down the system as a whole, will only be permitted in the global zone. An administrator logged into the global zone can monitor the activity of applications running in other zones and control the system as a whole. The global, or default, zone will always exist. * Isolation Zones allow the deployment of multiple applications on the same machine, even if the applications operate in different trust domains, require exclusive use of a global resource, or present difficulties with global configurations. Individual zones can have their own set of users and their own root password and when rebooted, any other zones running on the system are unaffected. * Virtualization Zones provide a virtualized environment that can hide details such as physical devices and the system's primary IP address and host name from the application. This can be useful in supporting rapid deployment and redeployment of applications since the same environment can be maintained on different physical machines. * Granularity Zones can provide isolation at almost arbitrary granularity. A zone does not require a dedicated CPU, physical device, or chunk of physical memory. These resources can either be multiplexed across a number of zones running within a single system, or allocated on a per-zone basis using resource management features available in the operating system. * Transparency Zones avoid changing the environment in which applications execute except when necessary to achieve the goals of security and isolation. Zones do not present a new API or ABI to which applications must be ported. Instead, they provide the standard Solaris interfaces and application environment, with some restrictions that affect applications attempting to perform privileged operations.

Remote Filesysemts, Network filesystems

those include: nfs, webdav, sshfs, openafs, coda, etc etc... Usefull stuff for nfs: mount options: rsize=8192,wsize=8192 ( default is 1024 and makes nfs slow, but is required for old nfsv2 servers ) soft ( soft If an NFS file operation has a major timeout then report an I/O error to the calling program. The default is to continue retrying NFS file operations indefinitely. ), hard is very very very bad when your nfs server dies ( or if network dies ) intr If an NFS file operation has a major timeout and it is hard mounted, then allow signals to interupt the file operation and cause it to return EINTR to the calling program. The default is to not allow file operations to be interrupted. retry=n The number of minutes to retry an NFS mount operation in the foreground or background before giving up. The default value is 10000 minutes, which is roughly one week. http://www.fs.net/

Using LVM

ALWAYS create your VGs with -i 32 ( 32M physical extents ), this allows for 2TB size arrays, with default you get only 256G.

Installing Oracle Xi/10g on Woody

Get Oracle10g ;)
get some diskspace, get some ram, get some swap, create users and groups for oracle ( oracle user is enough, you can go with group dba, user oracle, orainstall etc etc.. though.. )
apt-get install make rpm binutils gcc ln -s /usr/bin/awk /bin/awk ln -s /usr/bin/rpm /bin/rpm It's also nice to go and tasksel -> c/c++ development
Pretend you're a redhat: root@ox $cat > /etc/redhat-release Red Hat Linux release 2.1 (drupal) ^D
uncompress your install and run installation script: /opt/oracle/Disk1/runInstall
Make some choice, push some buttons, run some runme.sh scripts, ignore two compilation errors and voile'a: eyck@ox $ sqlplus Enter user-name: eyck@OX Enter password: Connected to: Oracle Database 10g Release 10.1.0.2.0 - Production

Shagma lyrics...

(speech)
Depuis la Grand Cataclysme, les Arkadiens vivaient blottis au centre de
la Terre. Ils avaient tout oublié de leur passé, ainsi l'avaient voulu leurs
anc?tres. Jusqu'au jour o? leur soleil, le Shagma, tomba malade. Alors
les enfants d'Arkadia os?rent entrer dans le musée interdit. Ils y
retrouv?rent quelques traces du passé mais aucun plan du Shagma.
Alors les enfants cré?rent puis envoy?rent vers la surface de la terre
leur messag?re : Arkana.

Setting up remote Subversion repository on debian (woody)

First, you need some packages, using backports.org is probably the easiest route.., add this:

deb http://www.backports.org/ woody subversion
deb http://www.backports.org/ woody apache2

to your /etc/apt/sources.list.

Subversion itself is also available at deb http://people.debian.org/~cjwatson/subversion-woody/ ./

apt-get install libapache2-svn subversion subversion-tools apache2-mpm-prefork

svnadmin create /var/lib/svn

chown www-user(or svn-user) /var/lib/svn

enable:

srv:/usr/share/doc/libapache2-svn# htpasswd2 -c /etc/apache2/dav_svn.passwd eyck New password: Re-type new password: Adding password for user eyck

# dav_svn.conf - Example Subversion/Apache configuration
#
# For details and further options see the Apache user manual.

# <Location URL> ... </Location>
# URL controls how the repository appears to the outside world.
# In this example clients access the repository as http://hostname/svn/repos
<Location /svn>

# uncomment this to enable the repository
DAV svn

# set this to the path to your repository
SVNPath /var/lib/svn

# The following allows for basic http authentication.  Basic authentication
# should not be considered secure for any particularly rigorous definition of
# secure.

# to create a passwd file
# # rm -f /etc/apache2/dav_svn.passwd
# # htpasswd2 -c /etc/apache2/dav_svn.passwd dwhedon
# New password:
# Re-type new password:
# Adding password for user dwhedon
# #

# Uncomment the following 3 lines to enable Basic Authentication
AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/dav_svn.passwd

# Uncomment the following line to enable Authz Authentication
# AuthzSVNAccessFile /etc/apache2/dav_svn.authz

# Uncomment the following three lines allow anonymous read, but make
# committers authenticate themselves

<LimitExcept GET PROPFIND OPTIONS REPORT>

Net::TLSFTP quest

Howto easily install stuff in your home directory ( without uid=0, root )

Get the toast:
```
 eyck@hostname:~$ wget -O- http://toastball.net/toast/toast|perl -x - arm toast
```
(actually, you shouldn't do that. You should download the toast script, review it to make sure it realy does what is should, and then you can try running it)

Prepare the environment:

 eyck@hostname:~$ ln -s .toast/armed/bin/ .

 eyck@hostname:~$ ln -s .toast/armed/man/ .

Now add something like this to your .bash_profile:

# set PATH so it includes user's private bin if it exists
if [ -d ~/bin ] ; then
    PATH=~/bin:"${PATH}"
fi

# do the same with MANPATH
if [ -d ~/man ]; then
    MANPATH=~/man:"${MANPATH}"
fi

And then load it:

 eyck@hostname:~$ . .bash_profile

Your PATH should look roughly like this: PATH=/home/eyck/bin:/bin:/usr/bin:/usr/bin/X11:/usr/X11R6/bin:/usr/local/bin:/usr/bin

Try it out:

 eyck@hostname:~$ toast arm openssh

After few lines of getting the package... and then compiling it... you should see the results:

 eyck@hostname:~$ bin/ssh -V
OpenSSH_3.7.1p2, SSH protocols 1.5/2.0, OpenSSL 0.9.6c 21 dec 2001

Congratulations! your toast is now ready to eat. You can now go berzerk:

 eyck@hostname:~$ toast arm mplayer

 eyck@hostname:~$ toast arm fluxbox

 eyck@hostname:~$ toast arm screen

Instant Messaging/Instant Messanger Quest.

I'm in quest for 'asynchronous bi-directional' communication protocol.

Starting point are:

IRC Internet Relay Chat, traditional workhorse in the field.
CIMD2 Nokia protocol for communicating with SMSC/telephones. Has few nice properties and quirks.
Jabber famous protocol that solves the problem - how to spy on people's chats in times when most IM's go encrypted.

asynchronous bi-directional - the most important thing, and different from most of the "normal" protocols, is the fact that system must be able to sand AND receive message in any given moment. "Normal" protocols like FTP/SMTP/POP3 etc, work this way:

client -> request -> server
client <- response <- server

so basicaly, on very low level of protocol - client can't receive anything from server until it asks for it. This something important in perl world - we've got Net::* clients, and many of those use object infrastructure of Net::CMD... this means that you're on your own if you want to create client for some IM...

Raphael - Carla Bruni


Lyric Raphael
Carla Bruni
Quatre consonnes et trois voyelles
C'est le prénom de Raphaël
Je le murmure ? mon oreille
Et chaque lettre m'émerveille
C'est le tréma qui m'ensorcelle
Dans le prénom de Raphaël
Comme il se m?le au a au e,
Comme il les entre-m?le au l
Raphaël ? l'air d'un ange
Mais c'est un diable de l'amour
Du bout des hanches
Et de son regard de velours
Quand il se penche
Quand il se penche mes nuits sont blanches
Et pour toujours
Hmm

J'aime les notes au go?t de miel
Dans le prénom de Raphaël
Je les murmure ? mon réveil
Entre les plumes du sommeil
Et pour que la journée soit belle
Je me parfume Raphaël
Peau de chagrin pâtre éternel
Archange étrange d'un autre ciel
Pas de délice pas d'étincelle
Pas de malice sans Raphaël
Les jours sans lui deviennent ennui
Et mes nuits s'ennuient de plus belle
Pas d'inquiétude pas de prélude
Pas de promesse ? l'éternel
Juste le monde dans notre lit
Juste nos vies en arc en ciel
Raphaël a l'aire d'un sage
Et ses paroles sont de velours
De sa voix grave
Et de son regard sans détour
Quand il raconte
Quand il invente je peux l'écouter
Nuit et jour
Hmm

Quatre consonnes et trois voyelle
C'est le prénom de Raphaël
Je lui murmure ? son oreille
Ca le fait rire comme un soleil
