msi Diagnostic logging

Windows Installer supports detailed logging as a powerful diagnostic tool. Logging can be enabled in the following ways:

* Command-line: If installing an MSI package from the command-line, the /L switch can be used to enable logging. For example, the following command installs Package.msi and outputs verbose logging to c:\Package.log:

msiexec /i Package.msi /l*v c:\Package.log

* Windows Registry: The following registry value can be used in Windows Server 2003, Vista, and XP to enable verbose logging:

Key: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer
Value Name: Logging
Type: REG_SZ
Data: voicewarmupx

* Local Policy The following local policy must be changed in Windows Server 2008. The above registry key is no longer used:

Start > Run and type mmc to open a blank management console.
File > Add/Remove Snap-In...
Local Computer Policy, Add, OK, OK
Expand Administrative Templates > Windows Components > Windows Installer
Select "Logging" choose the "Enabled" option box and type "voicewarmupx" without quotes

The resulting log is named MSI#####.log (where "#####" is a unique random identifier) and is placed in the user's Temp directory (the 'temp' directory location is per-user, and is pointed to by the environment variable %temp%).

* Group Policy: The following Group Policy setting can be used to manage logging on multiple systems:

Computer Configuration -> Administrative Templates -> Windows Components -> Windows Installer -> Logging.

* Windows Installer API: If installing an MSI package programmatically, the MsiEnableLog function call can be used to create a log file and set the logging level for the life of the calling process.

* MsiLogging property: Windows Installer 4.0 introduces the MsiLogging property, which can be set to a list of flags indicating what information to log. The flags are similar to the flags that can be added to the /L switch to msiexec.exe or to the Logging policy setting. If MsiLogging is used, the MsiLogFileLocation property will be set to the location of the log file.

Although verbose logs are very useful for diagnosing Windows Installer problems, they can be very long and difficult to read without practice. A quick way to find the location of a problem in the log is to open it in a text editor (such as Notepad) and search for the phrase "Return Value 3". This entry commonly appears in logs close to the point where a critical error has occurred. The Windows Installer SDK provides a tool called WiLogUtl, which parses and annotates Windows Installer log files.

To output debug information in the log file, pass "x" on the command line or add it to the Logging registry value. For example, the following command installs Package.msi and outputs debug, verbose logging to c:\Package.log:

msiexec /i Package.msi /l*vx c:\Package.log

How to Change User Password at Command Prompt

How to Change User Password at Command Prompt

How to use the net user command to change the user password at a Windows command prompt. Only administrators can change domain passwords at the Windows command prompt. To change a user's password at the command prompt, log on as an administrator and type: "net user * /domain" (without the quotation marks)

When you are prompted to type a password for the user, type the new password, not the existing password. After you type the new password, the system prompts you to retype the password to confirm. The password is now changed.

Alternatively, you can type the following command: net user . When you do so, the password changes without prompting you again. This command also enables you to change passwords in a batch file.

Non-administrators receive a "System error 5 has occurred. Access is denied" error message when they attempt to change the password.

Container is already locked

Sometime when automated OR Manual Virtuozzo backup process gets stuck OR sometime a VPS stuck while starting up OR stopping during this stage its impossible to make any changes on that VPS. You can stop the VPS or kill the process which is running. Making any updates or trying to restart the VPS shows message “Container CTID is already locked”.

Solution:

In case of Linux this error can be fixed by deleting the lock file located at /vz/lock/CTID.lck but in Windows there is no such file.

Following are the steps to unlock the locked Container

1) vzctl stop CTID –-skiplock (try this command twice till it doesn’t show that the container is not running)
This command might throw some ERROR but no need to worry.

2) vzctl start CTID –-skiplock
This Command will throw an error if the VPS is stuck while starting or stopping.

3) After the both the above command the status of the VPS will be locked, so you will have to allow sometime to unlock the stuck processes.

4) If the above command doesn’t start the VPS, stop the VPS using –skiplock option again and kill “vzlpl” process from the Task Manager. After that you will able to start the VPS normally.

5) and restart VZAgent service

net stop vzaop

net start vzaop

Helm 4.0.x upgrade to 4.1.x

there is some additional information to this topic: http://forums.webhostautomation.com/showthread.php?p=182350#post182350

Upgrade Instructions
4.0.x to 4.1.1 Upgrade

  1. The upgrade to Parallels Helm 4.1.1 requires a valid license with Upgrade Protection, or, in terms of Parallels licensing, a license that provides Software Update Service (SUS) which entitles you to version upgrade licenses throughout the life of your SUS. Read more about SUS: http://www.parallels.com/en/support/sus.
    You can validate your license by going to the Parallels Helm member area: http://www.webhostautomation.com/members.
    If you have a license without SUS, go to http://www.parallels.com/store/support/helm/ and reinstate your license. Otherwise, you will not be able to upgrade to Parallels Helm 4.1.1
  2. Download the Parallels Helm 4.0 to 4.1.1 Upgrade Tool from the following location: http://helm.download.webhostautomati...pgradeTool.exe.
  3. Run the tool and follow its instructions.

=========

First of all make sure that you have .net framework sp2 installed (for all versions) and your Helm is running. If no http://kb.parallels.com/en/5996 you should patch your helm, and re run helm upgrade

Second you should have ready to upgrade licenses for all your servers (SUS)

If you are ready you can run upgrade tool. Usually upgrade procedure takes about 30-40 mins.

NOTE!!! UPGRADE FROM HELM 3.0 TO HELM 4.0 IS ALMOST IMPOSSIBLE, IF YOU WANT TO SAVE YOUR TIME AND MONEY DO NOT PERFORM UPGRADE.

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 Xen LogoMicrosoft 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.

PDNS & named

I’ve met strange problem. We have primary DNS server as pdns and slave dns as named. In /var/named/named.zone slave zones are correctly included, but there are no zone files in /var/named

How I fixed the problem:

1. restart named

2. run hspc-dns-sync.pl –all at server side

Finnaly I received all zone files in /var/named

Slow Helm

Some times we have such problem like: “ohh God my f** Helm goes crazy, it takes 2-5 mins to load page, bull shit, bad product”

So first of all I wanna say - Helm is good product, and you should check your server because it is the main problem :).

Ok lets talk about reasons of the problem:

1. your IIS very loaded.

how to check: run task manager > processes sort by mem and check how much memory w2wp.exe use.

fix: try to restart IIS (run > cmd > iisreset) and try to load Helm CP. If at the begining Helm loads fast and then again become slow, so congratulation you found the reason

2. MSSQL server use more than 1.5 Gb of mem.

how to check: same as in 1.

fix: restart MSSQL server and then steps as in 1. but I want to say that this fix usually temporary because MSSQL begins to “eat” mem very soon :(

3. you have 1 Gb memory installed

how to check: if you have more than 50 web sites running at your server, so you should have at least 2 Gb of mem installed at your server.

fix: add memory

4. You have more than 1000 web sites.

how to check: if its your server then you know how many sites running at your server

fix: there is no fix( in windows

recommendation: install Linux with apache and migrate sites with “Me and my dog” to Linux

5. Virus

How to check: run from liveCD any antivirus

Fix: clean the viruses

How to Move Your Joomla! Site to a New Server

Things happen. Plans change. Websites outgrow current servers and need new servers. Hosting companies provide poor service, prompting a web master to decide to change servers. Whatever the reason, you might need to move your Joomla! installation from one server to another.

If you've been running a website for a while, you have probably already accumulated quite a bit of content and several 3rd party components and/or modules, and you do not want to start fresh with a new Joomla! installation. This article explains what I did to move HowToJoomla from my test server (howtojoomla.corywebb.com) to the server that it is on now.

Why not use a fresh install?

In my case, I probably could have. I only had about 4 or 5 articles on the test site, and I am using relatively few 3rd party CMT's (JomComment, TagBot, and JoomlaXplorer). But, I decided it would be easier just to move the installation I had to the new server, so I did.

You will want to move your Joomla! installation rather than re-install if you fit one or all of the following parameters:

  • Your site has accumulated a large amount of data in the database over time (sections, categories, content items, contacts, newsfeeds, etc.).
  • Your site uses multiple 3rd-part extensions already configured and/or customized for your site.
  • You just feel like trying it out to see if you can do it.
Step 1: Backup everything!

The first thing you want to do is backup all files within your Joomla! installation. Create a folder on your local system, and download all files to that folder using your ftp client application. I used FileZilla as my ftp client application to download all of my files to a folder on my desktop I named "howtojoomla".

Step 2: Export your database

Note: For this step, it really helps if you have phpMyAdmin installed on your server. Most hosting companies have phpMyAdmin already installed. If you are unsure, ask your hosting provider.

The second thing you need to do is export your Joomla! database. The best thing to do is to export it into an SQL file, which makes importing it easier in a later step. An SQL file will contain all of the necessary SQL commands for creating your database tables and filling them with your data. Be sure you export the entire database.

Step 3: Modify configuration.php

This step is very important. Go to the folder on your local system to which you downloaded all of your Joomla! files. In the first level folder, you will find the file named "configuration.php". Open this file with a text editor and make the necessary changes. At the very least, you will probably need to change the following parameters:

  • $mosConfig_absolute_path: This is the absolute server path to your new Joomla! installation. It will probably look something like "/path/to/joomla/installation".
  • $mosConfig_cachepath: This is the absolute server path to the cache for your Joomla! installation. It will probably look something like "/path/to/joomla/installation/cache".
  • $mosConfig_live_site: This is your website's url. It will be something like "http://www.yoursite.com".
  • $mosConfig_host: This is the location of the server that hosts your MySQL database. For most instances, this value will be "localhost". If you are unsure, ask your hosting provider.
  • $mosConfig_db: This is the name of your MySQL database.
  • $mosConfig_user: This is the database user name. Make sure this user has all privileges on your database.
  • $mosConfig_password: This is the password for your MySQL database user.
Step 4: Upload all of your files to your new server

Using an ftp client application (like FileZilla), upload all of your files to the location on your new server where you want to install Joomla!.

Step 5: Import your database to your new MySQL server

Using phpMyAdmin (or console commands if you are an advanced database administrator) and the SQL file you generated in step 2, import your old database into your new database.

Step 6: Test your new installation

Your move should now be complete, but please don't take my word for it. Test your site to make sure that everything is in it's proper place and working the way you expect it to. For example, if you did not use relative url's for your links on your old site, they will not work properly on your new site.

If you are uneasy or uncomfortable with this process, I strongly recommend that you hire a professional to do this for you.

Update: Another Resource

I just came across a resource called JoomlaCloner which automates much of this process for you. It has a commercial license, so unfortunately it is not free. The base price is $49.95 for 1 year support and upgrades. I have never used it, so I cannot speak for whether or not it is a good component. I just wanted to make you aware of it.

UPD: Additional for Joomla 1.5


Edit configuration.php

You have to tell Joomla to use the new database data. Open the configuration.php file on the new server, and edit the following variables to fit the new database and FTP settings:

var $log_path = 'yourfullserverpath/logs';
var $tmp_path = 'yourfullserverpath/tmp';
var $live_site = 'http://www.mysite.com';
var $ftp_host = '127.0.0.1';
var $ftp_port = '21';
var $ftp_user = 'myftpuser';
var $ftp_pass = 'myftppassword';
var $ftp_root = 'myftprootfolder';
var $host = 'mymysqlhost';
var $user = 'mysqluser';
var $db = 'mysqldatabasename';
var $password = 'mysqlpassword';

Convert ape to mp3 in linux (Fedora)

Виникла у мене проблема з тим щоб конвертнути ape в mp3 під лінухом, погугливши я знайшов наступну процедуру вирішення цієї проблеми.

використовувати ми будемо наступний скріпт:

ape2mp3

#!/bin/bash
echo "Brian's Archive CUE/FLAC Splitter v0.1"
echo "No sanity checking in place. Be careful."

if [ $# != 2 ]
then
echo ""
echo "Usage:"
echo " $0 cue_file ape_flac_file"
echo ""
exit 1
fi

#Get the filenames
cuefile=$1
flacfile=$2

#Other variables
tracks=$(cueprint -d '%N' "$cuefile")

#Get the filenames into an array
count=1
while [ $count -le $tracks ]
do
tracknames[$count]=$(cueprint -n$count -t '%p-%T-%02n-%t' "$cuefile"|sed -e s@/@,@g)
count=`expr $count + 1`
done

#Load up the ID3 tag info into variables for later use
id3count=1
while [ $id3count -le $tracks ]
do
artist[$id3count]=$(cueprint -n$id3count -t '%p' "$cuefile")
album[$id3count]=$(cueprint -n$id3count -t '%T' "$cuefile")
tracknum[$id3count]=$(cueprint -n$id3count -t '%02n' "$cuefile")
title[$id3count]=$(cueprint -n$id3count -t '%t' "$cuefile")
echo "Artist: ${artist[$id3count]}"
echo "Album: ${album[$id3count]}"
echo "Track No: ${tracknum[$id3count]}"
echo "Song Title: ${title[$id3count]}"
id3count=$[$id3count + 1]
done

#Output general file information
cueprint -d '%P - %T\n' "$cuefile"
echo "Total number of tracks: " $tracks

#Split this bitch
cuebreakpoints "$cuefile" | shntool split -a '' -n '%02d' -o wav "$flacfile"

#Convert those waves into mp3s
convertcount=1
while [ $convertcount -le $tracks ]
do
wavenum=`printf "%02d" $convertcount`

lame --add-id3v2 --noreplaygain -b 320 --ta "${artist[$convertcount]}" --tl "${album[$convertcount]}" --tn "${tracknum[$convertcount]}" --tt "${title[$convertcount]}" "$wavenum.wav" "${tracknames[$convertcount]}.mp3"
rm "$wavenum.wav"
convertcount=$[$convertcount + 1]

done
