Windows Media Player not showing on IE8 part 2
Posted by adminix Labels: Basic PC Troubleshooting, WindowsOkay so given that you have already installed the Internet Explorer Add-on, the windows media player still does not show up. A possible answer for this is maybe due to Windows Media Player 11 not being the default media player.
To set it to be the default media player, follow this steps from the Microsoft KB:
1. Open the Control Panel and navigate to Add/Remove Programs.
2. From the Add/Remove Programs, click Set Program Access and Defaults.
3. In the Choose a configuration box, double-click Custom.
4. In the Choose a default media player area, click Windows Media Player, and then click OK.
Hope this helps.
This happens when a website requires windows media player. It just shows an "x" whenever you try accessing the link.
There is two possible causes for this. Its either you haven't installed the Windows Media Player addon for IE8 or your default media player is not set to use WMP.
To install the Windows Media Player addon, navigate to the website that is having problem playing music or videos. A prompt should ask you if you want to run the addon.
Right click and click run add-on on all websites.
Click run when it prompts you the activex thingy.
That its. You should be able to see the windows media player.

PHPIZE is a part of the PHP Development package. All you have to do is to login to your linux server, and execute:
yum -y install php-devel
And that's it. Installation should be complete in less than 5 minutes.
Here's a quick how to in installing yum to your VPS. I don't know about you but Virtuozzo or the Parallels team told us that it should be included in the VPS template. I am running Virtuozzo version 4 and for some reason, yum isn't installed. You should be able to install it with a flick by trying out my solution:
Linux distro: Centos 4.4
1. Login to your box thru ssh using any of your favorite ssh clients. I used mRemote.
2. Create the directory yum under /usr/src. (Optional)
3. Download the following files using the wget tool:
a. python-urlgrabber-2.9.6-2.noarch.rpm
b. python-sqlite-1.1.6-1.i386.rpm
c. python-elementtree-1.2.6-4.i386.rpm
d. python-urlgrabber-2.9.6-2.noarch.rpm
e. sqlite-3.2.2-1.i386.rpm
Usage: wget
Sample: wget http://mirror.centos.org/centos-4/4/os/i386/CentOS/RPMS/python-2.3.4-14.7.el4.i386.rpm
4. Run this command:
# rpm -Uvh *rpm
5. Download yum:
a. centos-yumconf-4-4.3.noarch.rpm
b. yum-2.4.0-1.centos4.noarch.rpm
c. yum-metadata-parser-1.0-8.el4.centos.i386.rpm
6. Proceed with item no.4.
You should be able to see a successful installation afterwards.
For an updated version of the yum dependencies and yum itself, visit Centos' repository. And speaking of dependencies, other's might encounter a dependency issue when installing components manually. Do drop by and post a quick comment and we'll try to sort things out.
Have a nice yum day!

Updating Plesk Control Panel to Higher version : Fiasco
Posted by adminix Labels: Linux, Mysql, Plesk, Plesk for Linux
Well what a week. Thank you readers for dropping by at my tech blog once in a while. I know i don't frequently update it due to lack of time but here I am, ready to post new ideas again.
Yesterday, we ran into a "not so difficult" problem, at all. Here's the story.
We need to install the Sitebuilder package since one of the clients need the application. We installed the Sitebuilder support using the Plesk updater. Installation successful as per Plesk but upon checking, still no sitebuilder support. Next step, we did an upgrade from Plesk 8.4 to Plesk 8.6. We got a prompt again saying that the upgrade was successful. Ok got it. But, after a few minutes, Plesk started acting really weird. We checked the status of the PSA service and here comes the real fiasco. We got an error of course:
psa dead but subsys locked
Oh not again. I happen to encounter this kind of problem on the http, vsftp etc daemons. But I can easily fix them by just restarting the machine or deleting the corresponding /var/lock/subsys file and then start the service again. I did this for a couple of times for the PSA service but to no avail, Plesk isn't just working! I looked at the logs and I just can't find any clues there.
Well, what we did is to email the Parallels Support team. We didn't got any answer overnight so we are feeling a bit hopeless about the case. The next morning, ideas are fresh and we started looking at the key answer to the problem.
/tmp/autoinstaller3.log
So yup. I looked into the updater logs and found this:
Trying to establish test connection... ERROR 1044 (42000): Access denied for user 'root'@'%' to database 'mysql'
Trying to establish test connection... ERROR 1044 (42000): Access denied for user 'root'@'%' to database 'mysql'

again

Please, contact product technical support.
Unable to connect to Mysql? Duh?. FYI, the script looks into the .psa.shadow for the mysql password. But here's the dish. We can login into the mysql server using the password defined in the .shadow file. So how come we cannot run the upgrade without the creepy errors?
Per Parallels support, we we're running a "mixed" version of Plesk. Probably because of the failed upgrade.
Just in case you noticed this error, I stumbled into a knowledgebase entry regarding the /root/.my.cnf file.
SYMPTOMS:
Plesk upgrade or installation fails with the error in upgrade log:
Access denied for user 'admin'@'localhost' (using password: YES)\n")
RESOLUTION:
Make sure that there is no /root/.my.cnf file with MySQL password. Plesk uses environment variable to pass the password to MySQL server, but the .my.cnf file has greater priority and MySQL uses the password from the file. If it does not match, restoration fails.
Also, check that you are able to connect to MySQL from the command line with:
# mysql -uadmin -p`cat /etc/psa/.psa.shadow` psa
You should not have any .my.cnf file on the /root directory. Although I tried creating a symlink to /etc/my.cnf. But it didn't made any difference. The error for the missing .my.cnf was gone but we we're still not able to finish the upgrade.
SOLUTION
We replaced the admin password to a more simplier password.
Login into the mysql server. and then run this command:
UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='admin';
and then
flush privileges;
Do not FORGET to update the /etc/psa/.psa.shadow file for the new password.
Then re-run the upgrade.
# cd /root/86/dist-rpm-CentOS-4.2-i386
# rpm -Uvh --force base/*.rpm opt/migration/*.rpm opt/backup/*.rpm
Finally, Plesk is now behaving perfectly fine! There you go. A complex problem with a really simple solution.
Hope this sheds a light to anyone out there having the same problem.
Current Mood: Fulfilled but exhausted.
Well what's your busiest day of the week?
I work 6 days a week and most of the time im busy. But for me, it's Saturday. I do automated backup of some of the system files but of course, the thing still needs supervision! But still loads of stuff needs to be done.
Saturday, Saturday and Saturday.
Good luck to me!

Getting defpackagemng errors when logging into Plesk Control Panel
Posted by adminix Labels: Knowledgebase, Plesk for windows
When attempting to log into Plesk Control Panel the following error message is received:
DefPackageMng() constructor failed: defpackagemng failed: Access is denied.(Error code 5) at CreateProcess 'C:\\WINDOWS\\system32\\cmd.exe /c ""C:\\Plesk\\admin\\bin\\defpackagemng.exe" --get"' at execUtil C:\\Plesk\\admin\\bin\\defpackagemng.exe --get on C:\\Plesk\\admin(PleskSrvClient::execUtil line 420)at execute console command --get(vconsoleapp::start line 128) at execute C:\\Plesk\\/admin/bin/defpackagemng --get(vconsoleapp::run line 138)
RESOLUTION
Such error occurs when Plesk Control Panel web server service cannot access the C:\Windows\System32\cmd.exe ( C:\Windows\SysWOW64\cmd.exe on 64bit Windows version). This may happen when administrator has manually changes permissions to access the file. User SERVICE should have Read+Execute; Read on the file.
The following permissions should be set on cmd.exe :
- Administrators - Full Control
- System - Full Control
- Service - Read+Execute; Read
- Interactive - Read+Execute; Read
The file owner should also be administrator, otherwise it will not be possible to change these. File owner can be checked in file’s Properties, Security tab, Advanced button, Owner tab.

Website asks for password - Plesk for Windows
Posted by adminix Labels: Knowledgebase, Plesk for windows
SYMPTOMS
It's impossible to access website - authorization prompt appears.
CAUSE
There may be several reasons of this issue. To determine them, the following conditions need to be checked:
1. There should be read + execute permissions for IUSR_
2. Root directory for the domains can be under Plesk protection.
3. Passwords for system user and IIS user can be out of synchronization.
RESOLUTION
1. Go to %plesk_vhosts%\domain.com\httpdocs directory and check permissions for IUSR_
2. It can be checked using Plesk Control Panel. Go to Plesk, domains, domain.com, Protected URLs. If the root directory "/" is present there, it needs to be removed.
3. The password can be synchronized using the following command:
"%plesk_bin%\websrvmng.exe" --update-anon-password --domain-name=

How to install PHP5 with legacy Plesk versions
Posted by adminix Labels: Knowledgebase, PHP, Plesk for windows
Plesk 7.5.5-7.6.1versions support this version of PHP but they are not able to manage PHP4 and PHP5 at the same time only PHP4 or PHP5.
If your Plesk version is 7.5.5 or higher you can follow these steps to install PHP5 at your server:
1. Download PHP5 Windows Binaries:
- PHP 5.x.x zip package
- Collection of PECL modules for PHP 5.x.x
2. Remove current PHP4 extensions from Register Web Service Extensions in IIS:
Open command prompt:
cscript c:\windows\system32\iisext.vbs /RmFile "%plesk_dir%\Additional\php\php.exe"
cscript c:\windows\system32\iisext.vbs /RmFile "%plesk_dir%\Additional\php\sapi\php4isapi.dll"
3. Rename folder "%plesk_dir%Additional\Php" to "%plesk_dir%Additional\Php4"
4. Re-register web service extensions for PHP4.
Open command prompt:
cscript c:\windows\system32\iisext.vbs /AddFile "%plesk_dir%Additional\php4\php.exe" 0 PHP 1 "PHP Extensions"
cscript c:\windows\system32\iisext.vbs /AddFile "%plesk_dir%Additional\php4\sapi\php4isapi.dll" 0 PHP 1 "PHP Extensions"
cscript c:\windows\system32\iisext.vbs /EnFile "%plesk_dir%Additional\php4\php.exe"
cscript c:\windows\system32\iisext.vbs /EnFile "%plesk_dir%Additional\php4\sapi\php4isapi.dll"
5. Unzip PHP 5.x.x package into %plesk_dir%Additional\Php.
6. Unzip Collection of PECL modules into %plesk_dir%Additional\Php\Ext.
7. Register PHP5 extension in IIS manually:
Open command prompt:
cscript c:\windows\system32\iisext.vbs /AddFile "%plesk_dir%Additional\php\php-cgi.exe" 0 PHP 1 "PHP Extensions"
cscript c:\windows\system32\iisext.vbs /AddFile "%plesk_dir%Additional\php\php5isapi.dll" 0 PHP 1 "PHP Extensions"
cscript c:\windows\system32\iisext.vbs /EnFile "%plesk_dir%Additional\php\php-cgi.exe"
cscript c:\windows\system32\iisext.vbs /EnFile "%plesk_dir%Additional\php\php5isapi.dll"
8. Backup or rename C:\Windows\php.ini.
9. Put attached to this article file php.ini to C:\Windows\php.ini.
10. Configure default C:\Windows\php.ini according to Plesk configuration.
Set parameters:
extension_dir = "%plesk_dir%Additional\Php\ext"
Example:
extension_dir ="C:\Program Files\SWsoft\Plesk\Additional\Php\ext"
11. Re-configure webmail in IIS to use PHP4 because HORDE webmail does not work on PHP5.
IIS Management, Web Sites, webmail(default), Properties, Home Directory tab, Configuration button, Application Extensions, edit value for `.php` extension, set to "%plesk_dir%additional\php4\php.exe"
Edit "%plesk_vhosts%webmail\horde\php.ini"
Change parameter:
extension_dir = "%plesk_dir%Additional\Php4\extensions"
Example:
extension_dir ="C:\Program Files\SWsoft\Plesk\Additional\Php4\extensions"
12. Make sure that PHP5 has been detected by Plesk. You can check in Plesk, Server, Components Management, Web Scripting section PHP should be listed there. If not, you need to check whether all the steps were done properly.
13. Reconfigure domains web-sites in IIS to use PHP5.
"%plesk_bin%\websrvmng.exe" --reconfigure-all

How to install CDONTS on Windows 2003 Server
Posted by adminix Labels: Knowledgebase, Plesk for windows
Microsoft Windows Server 2003 does not install Collaboration Data Objects (CDO) for NTS (CDONTS). Therefore, applications that use CDONTS do not function on a Windows Server 2003-based computer. Windows Server 2003 provides improved alternatives to CDONTS.
To make CDONTS functioning on a Windows Server 2003-based computer, use one of the following solutions:
1. Download an attached CDONTS.ZIP file. Once you have downloaded it unzip the CDONTS.DLL and put it into %systemroot%\system32 folder (C:\Windows\system32 by default). You can also get CDONTS.DLL from your Windows 2000 CD.
2. Register the CDONTS.DLL component on your server using the following command:
regsvr32 "%systemroot%\system32\cdonts.dll"
For example:
C:\WINDOWS\system32>regsvr32.exe cdonts.dll
3. After you have registered your CDONTS.DLL component you need to check whether your SMTP service is running.
Go to Administrative tools, IIS and expand your local machine. If SMTP service is listed then it is installed, else it's necessary to install this service.
To install SMTP perform the following operation:
Go to Control Panel, Add/Remove Programs, Add/Remove Windows Components, Application Server, IIS, Check on SMTP service, Click OK.
4. Change the port number for SMTP service. Default port is 25. Use 25 only if you don't have another SMTP service running. If another SMTP service is already running on your server you should switch IIS SMTP port to another, for example to 8025.
You can do through IIS management console: Control Panel, IIS, expand `local computer`, SMTP, Properties, General tab, click on Advanced button, Edit.
5. Configure SMTP service. The main things are to set a valid full-qualified domain name for SMTP service: Control Panel, IIS, expand `local computer`, SMTP, Properties, Delivery tab, click on Advanced button and configure Security for SMTP service.
It's necessary to grant permissions to IIS_WPG standard IIS Worker Process Group. Control Panel, IIS , expand `local computer`, SMTP, Properties, Security tab , click on Add button, cick Object types... button, check on Groups item, click OK, type IIS_WPG as object name to add , click OK.
Additional setting: Choose Authentication and tick Anonymous Access and Integrated Windows Authentication. Click OK, and then click CONNECTION. Configure RELAY settings as you wish. Click the DELIVERY tab then click ADVANCED. Set the MAX hop count to whatever you like but we recommend at least 20
Now IIS SMTP service is configured and ready to work.

You may create Service Container on a Virtuozzo hardware node using 'vzsveinstall' utility:
# vzsveinstall -D DISTRIB_DIR -s SERVICE_CT_IP
where
- DISTRIB_DIR - path to Virtuozzo distribution directory hierarchy on a server. F.e. if you have the Virtuozzo distrib on your server in the folder /root/Rel400 then DISTRIB_DIR should be /root/Rel400/;
- SERVICE_CT_IP - IP address to be assigned to Service Container;
Please refer to man page on 'vzsveinstall' utility for additional information.
Please note - OS template 'redhat-as3-minimal' must be installed on a hardware node and cached before Service Container may be created. If you have no that template on a node please do the following:
- install OS template 'redhat-as3-minimal', corresponding RPM package is located in the folder 'virtuozzo/SVE' inside Virtuozzo distrib (in Virtuozzo 3.x it is the folder 'HW/SVE');
- create OS template cache using 'vzpkgcache' command on a node.
If Virtuozzo server has been updated since the very first release (using 'vzup2date' utility or manually) then you need to apply all needed updates to the Service Container as well. Updates downloaded by 'vzup2date' utility are usually located under /vz/vzup2date/3.0.0/TU-3.0.0-* dirs on a Virtuozzo server. You may apply them to the Service Container using 'vzsveupgrade' utility using this simple script:
# for i in `find /vz/vzup2date/$(awk '{print $NF}'
If you need to re-create Service Container then you may destroy the existing one using 'vzctl destroy 1' utility (container must be stopped first), then create it from the scratches and apply available updates as it is described above.
Iptables NAT module does not work in container
Posted by adminix Labels: Knowledgebase, Linux, Virtuozzo
SYMPTOMS
NAT module does not work in container, you get "can't initialize iptables table 'nat'" error:
# iptables -t nat -L -n
iptables v1.2.11: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
The following Iptables modules settings are configured on the hardware node:
# cat /proc/net/ip_tables_targets
LOG
TOS
TCPMSS
REJECT
ERROR
# grep con /etc/modprobe.conf
options ip_conntrack ip_conntrack_disable_ve0=1
RESOLUTION
If order to enable NAT you should perform the following actions on the hardware node:
- stop Virtuozzo service and all containers:
# service vz stop
- reconfigure IPtables module "ip_conntrack":
# sed -i '/ip_conntrack/ d' /etc/modprobe.conf
# echo "options ip_conntrack ip_conntrack_disable_ve0=0" >> /etc/modprobe.conf
- restart IPtables service:
# service iptables restart
- start Vituozzo service and all CTs:
# service vz start
