mod_dphpbb3_last_topics php warnings

 

Today after installing such pretty tool as  mod_dphpbb3_last_topics I received a ton of such errors

Warning: cannot yet handle MBCS in html_entity_decode()! in helper.php in line 130

After googling I found this article. I tried to replace:

$title = html_entity_decode($title, ENT_QUOTES, 'UTF-8'); with $title = utf8_decode($title);

but it brakes UA/RUS lang. After brainstorm I made following changes in code:

Was:

$title = html_entity_decode($title, ENT_QUOTES, 'UTF-8');

Become:

$title = html_entity_decode($title);

I have just committed a monster pf diff that is basically a rewrite of
the entire NAT part.

seperate rules for nat, rdr etc are gone.

nat and rdr become actions on regular rules.

simple rulesets are converted like this:

nat on $ext_if to ($ext_if)
becomes
match out on $ext-if nat-to ($ext_if)

more complex rulesets require some thought. since the weird
difference in matching order is gone (nat/rdr were first match) you
might have to reverse things and use your brains :)

the new NAT code is very very very flexible. every matching "match"
rule changes the adress on the fly (not really, but that is what it
looks like for subsequent rules), and you can nat or rdr multiple times.
for pass rules, only the last matching one matters.

so given
match out on $ext_if nat-to 1.2.3.4
match out on $ext_if to 1.2.3.4 nat-to 5.6.7.8
both rules will match and 5.6.7.8 will be the new src address.
however, with
pass out on $ext_if nat-to 1.2.3.4
pass out on $ext_if nat-to 5.6.7.8
ONLY the second one matters for NAT. same semantic that match rules
have for a lot of other stuff (altq, rtable, log, scrub).

the core logic, that relies on the big state table rewrite ryan and I
(with help from otehr developers of course) did last year, allows for
nat and rdr in any direction, but for now we prevent that in pfctl and
force nat outbound and rdr inbound, there are nontrivial implications
for the routing afterwards - if you rdr outbound, the packet will go
out on the interface it was seen on, even if the route for the address
rdr'd to actually points to a different interface. with NAT there are
similiar implications for the return traffic. since they are useful
nontheless I tend to remove the check in pfctl and document the
implications, but one thing after each other.

the diff is over 3000 lines, and makes pf about 800 lines smaller
than it was before. more cleanup is possible on top of this, but as
said before, one step at a time.

to add another data point how important hackathons are... this was
almost entirely written at c2k9 in edmonton and "finished" (minus a
few bugs fixed later) the week thereafter on bob's couch. while the
diff was almost entirely written by me, getting this actually into the
tree was a concerted effort by many developers. claudio adjusted ftp-proxy,
sthen ported that adjustment over to tftp-proxy, reyk adjusted relayd.
many people were testing a lot, I'm sure I forget a few, but at least
krw, sthen, claudio, reyk, dhill and dlg (who was insane enough to
throw this on production firewalls with significant importance) helped
a lot. igor did most of the manpage work. theo helped getting it in, a
lot. thanks guys.

and now it is your time. test this as much as you can, to avoid
surprises in 4.7, and bugs showing up after release... we really want
to find them beforehands, right?

Встановлення Xen на Debian Etch 4.0

Основна стаття http://mediakey.dk/~cc/installing-xen-on-debian-etch-40/
Переклад Михайло "veselujm" Веселовський

Протягом довгого часу я випробуав багато технологій віртуалізації: Xen, VMWare, і Microsoft VM. Я з впевненістю можу сказати що всі вони придатні для використання, але VMWare і Microsoft’s VM є більш вялими ніж Xen. Цих вихідних я розгорнув свій перший сервер на базі Debian Etch 4.0 і Xen. І все запрацювало з "коробки"

Тут я опишу кроки які я зробив щоб поставити Xen на Debian Etch:

sudo apt-get install xen-linux-system-2.6.18-4-xen-686 libc6-xen bridge-utils

Грузимось в нове ядро з встановленим Xen

sudo reboot

Потім настроюємо настройки мережі в /etc/xen/xend-config.sxp. Вмикаємо network bridge:

(network-script network-bridge)

Встановлюю xen-tools:

apt-get install xen-tools

Xen tools це пакет який включає в себе різноманітні утиліти для Xen, утиліта для створення віртуальних машин тощо.

Редагуємо настройки ядра і initrd в /etc/xen-tools/xen-tools.conf, так щоб вони були подібними до ваших системних.

Взнаємо як ядро і initrd називаються у вашій системі:

ls /boot/vmlinuz*
/boot/vmlinuz-2.6.18-4-686 /boot/vmlinuz-2.6.18-4-xen-686

і

ls /boot/initrd*
/boot/initrd.img-2.6.18-4-686 /boot/initrd.img-2.6.18-4-686.bak /boot/initrd.img-2.6.18-4-xen-686

Змінюємо рядки:

#
# Default kernel and ramdisk to use for the virtual servers
#
kernel = /boot/vmlinuz-2.6.18-4-xen-686
initrd = /boot/initrd.img-2.6.18-4-xen-686

В наступному кроці змінюємо наступні рядки в xen-tools.conf

dir = /home/xen
debootstrap = 1
size = 4Gb # Розмір диску
memory = 128Mb # Память
swap = 128Mb # Своп
fs = ext3 # використовувати файлову систему EXT3 для створення дисків
dist = etch # Стандартиний дистрибутив для встановлення
image = sparse # Визначаємо тип диску повний чи частинами

Створюємо домівки для наших віртуальних машин:

mkdir /home/xen
mkdir /home/xen/domains

Тепер ми готові до створення віртуальної машини

xen-create-image -hostname=mailserver -ip=10.0.0.21 -netmask=255.255.255.0 -gateway=10.0.0.1 -passwd

Після чого новостворену віртуалку можна запустити:

xm create mailserver.cfg

У випадку появи наступної помилки:

Error: Device 0 (vif) could not be connected. Backend device not found.

Потрібно перевірити чи ви увімкнена підтримка network bridge, “(network-script network-bridge)”, в /etc/xen/xend-config.sxp після додавання потрібно пергрузити демон xen /etc/init.d/xend restart. Здопомогою команд “xm list” чи “xentop” можна подивитись яка віртуалка зараз крутиться:

debian5:# sudo xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 874 1 r----- 657.9
mailserver 3 128 1 -b---- 8.0

Базуючись на моєму досвіді використання і впровадження технолоїй віртуалізації , а думаю що Xen це саме те для впровадження Linux і Linux-based технологій і це показує що вони готові до використання вже тепер. Технології віртуалізації вже тепер готові до впровадження в великих компаніях і дата центрах, і вони допомагають спростити настроювання, впровадження і встановлення працівникам, І я думаю що найближчі роки технології віртуалізації будуть грати важливу роль на серверному ринку.

about torrent

short howto about P2P(torrent in this case) for newbie

1. first of all you need software for using *.torrents files, for example I use uTorrent it can be downloaded from http://www.utorrent.com/downloads/
2. you need one small file called torrent. if you already have it you need only add it into your torrent client if none you can find something in such large torrent databases as mininova.org, thepiratebay.com, isohunt.com etc.

How to fix: locate: can not open `/var/lib/mlocate/mlocate.db’: No such file or directory
