Develop website from any computers

2011-02-28T16:48:00.001+07:00

I'm using 2 computers for daily use. Sometime I develop website so I need a way to work on the web that I develop from those 2 computers.
To achieve that I use
- Dropbox => this will be used to synchronize all files to any computer
- Apache => You will need this because IIS not support user_dir mod
- PHP ( this will depend on what kind server-side language do you use)

For the first step install Dropbox on your computer. After that install Apache web server.
Now create directory public_html under your dropbox folder.
Dropbox folder at my computer located at "C:\Users\Ronaldo\Documents\My Dropbox" for newer version the dropbox folder located at "C:\Users\\Dropbox"

Now uncomment this lines at httpd.conf
LoadModule userdir_module modules/mod_userdir.so
and
Include conf/extra/httpd-userdir.conf

now the edit the httpd-userdir.conf , here my httpd-userdir.conf looks like

# Settings for user home directories
#
# Required module: mod_userdir

#
# UserDir: The name of the directory that is appended onto a user's home
# directory if a ~user request is received. Note that you must also set
# the default access control for these directories, as in the example below.
#
UserDir "C:/Users/*/Documents/My Dropbox/public_html"

#
# Control access to UserDir directories. The following is an example
# for a site where these directories are restricted to read-only.
#

AllowOverride FileInfo AuthConfig Limit Indexes
Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec

Order deny,allow
Allow from 127.0.0.1
Allow from localhost
Deny from all

Order deny,allow
Allow from 127.0.01
Allow from localhost
Deny from all

restart the apache web server service. After that, access your home directory web, http://localhost/~username,
so for me it will be http://locahost/~ronaldo , after that put the website that you will develop under your public_html folder, which locate inside your Dropbox folder. Dropbox will synchronize every changes under it own directory.

NOTE: This is for development only..

Some improvement that needed by Win 2008 Core

2009-06-29T12:35:00.002+07:00

For few days I’m using Windows 2008 Core. It’s a good idea but for me still need some improvement. Here are the improvement that I think necessary to windows 2008 Core

1. Fixed the command prompt. make a smart command prompt, take example from linux command promot (nuff said).

2. Fixed the command prompt (again). In Linux I can resize the command prompt. Windows command prompt horrible, because sometime I need to get long output from a command.

3. Make a decent text based editor.. try to take example from VI.

4. Why on earth we still need RDP for text based environment. Just make a decent SSH server.

Other than that I like to work with Win 2008 Core, I think it very useful when you want to make RODC and File server at branch office.

My Windows 7 Experience

2009-04-02T12:34:00.004+07:00

After using vista for more than a year I just sick with it so damn slow. It took several minutes until my computer become usable. Sometime when I open application usually, I go to pantry to make tea or coffee. Also on vista my HardDrive is constantly busy this cause by windows search, that keep indexing my files even when my computer not in idle mode. Also when I try to archiving my mail, my vista system become completely useless. The bottom line is my vista experience is a frustrating experience.
Then come Windows 7 After see the performance on my friend laptop I decided to remove Vista, then install Windows 7.
Even though still in beta version, the performance is very much better than Vista, even with SP1 installed. I think this vista should be. Microsoft must provide free upgrade for all the Vista user because the software is a crappie one, and most of those who buy new laptop/computer not have much option(Except you build your own computer). I think that only a dream because no way Microsoft provides free upgrade for all the Vista users (except those who buy vista after June).

Beside the performance stuff what I like from Windows 7 is the Aero Peek , and also the location of the Show Desktop button. Also the New task bar (or super bar). Basically the Interface is just awesome.
Ok enough with all whining stuff. I install Windows 7 on Thinkpad T61, Here my Laptop Spec
Model: Thinkpad T61
Processor: Core 2 Duo 1,8 Ghz
Memory: 4 GB
VGA: Quadro 140 NV M
Disk: 250 GB (20 GB used for Linux)
I use my laptop for working also to play game and web development with PHP
Here some of application that I use on my laptop:- iTunes
- Some Thinkpad Goodies( Active Protection System, Ultranav Utility, On Screen Display)
- Ultra ISO
- Winrar
- MySQL Server 5.1
- MySQL Tools for 5.0
- Google Chrome
- Firefox (My Primary Browser)
- Free Download Manager
- Launchy
- Cisco VPN Client (ver. 5.0.04) to Connect to my workplace
- Songbird
- VMWare Workstation (There is problem with NAT mode)
- Putty ( to do some thingy at Linux Server)
- Tom Clancy's HAWX
I also use Eclipse for PHP development. For the PHP it seems there are problem with version 5.29-1 because php cannot parse the location of extension_dir, I already set the extension directory on php.ini file but still not working, after I revert to PHP version 5.28 it just work. Oh yeah for web server I use IIS7.5 (which came with windows 7).

There are few applications that still I’m not try yet on Windows 7 such as nmap, Process explorer and Process Monitor.
For drivers I use driver for vista. After all Windows 7 only an upgrade from Windows Vista (that’s why the version number is 6.1).
And for the gaming part, it very….very…very… good.
The bottom line is, if you willing to take some risk throw your vista then replace it with Windows 7.. Can’t wait until the final version release.

Here some picture of from Windows 7 on my laptop

And the winner is Chrome, the browser from google

2008-09-03T15:18:00.003+07:00

Today I just download Chrome which a new browser from Google, so I perform Java Script benchmark for each browser that installed on my laptop, from the result looks like the browser from Google is the winner , I not try safari yet, because it’s not installed on my laptop

Publish NTBackup log to Internal Web server

2008-03-14T14:14:00.005+07:00

Creating a web based backup log for your NTBackup

NTBackup is a backup tools from microsoft, it's usually already installed on your windows
machine. After the backup finish NTBackup create a backupog, but the sucks thing is, that
we can not change the directory where NTBackup log reside. The backup log locate at
"C:\Documents and Settings\%USER%\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data"

At my office we use NTBackup to perform the system state backup, and the backup result need to be checked every morning.
Because the NTBackup run with administrator priveledges, So i need to create a way so other people can review the backup
file without login to that server. And the answer is to publish the backuplog to our internal web server.

To do that I use rsync to syncronize the backup log our Linux based web server. But there's a problem with the logfile,
after it was syncronized using rsync, the problem related with character encoding. If we open that backup log on firefox It will show funny characters (see image bellow)

To handle this problem I use python script to change the encoding.
This script also will run the rsync command and generate HTML file.
I will post this python script on my next blog.

To Configure rsync on windows see Brent Noris Homepage about installing rsync on windows
Here the part of my rsync configuration to point to the NTBackup Log directory
[backuplog]
path = C:/Documents and Settings/Administrator/Local Settings/Application Data/Microsoft/Windows NT/NTBackup/data
read only = yes

After you finish configure the rsync on your windows machine, edit your crontab, then add the python script to your crontab entry.

Compatibility Problem between Citrix Memory Optimization and SAP GUI.

2008-01-25T15:00:00.000+07:00

If you published your SAP GUI to the Citrix PS, than there is a chance you get an error message like this "CSapEditorCtrl::GetObject: Object x does not exist". This error caused by Incompatibility between the SAP GUI and Citrix Memory Optimization. To solve this error you must exclude the SAP GUI from Citrix Memory Optimization. To do that here the step
1. Deactivate Citrix Memory Optimization, to desctivate this feature, go to Citrix Management Console
Click Properties at your Farm Name, then Memory/CPU Utilization Management Disable the memory Optimization
2. Exclude the SAP GUI from Citrix Memory Optimization Process.
Open the register editor(regedit), see the "HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\SFO\ProcessExclusionList", for example if yours
SAP GUI Located at "C:\Program Files\SAP\Front End\SAPGui", than add entry for DWORD which contain "C:\Program Files\SAP\Front End\SAPGui\*.*". Set the Value data to 0.
After that run the ADSCleaner.exe, this tools will list and delete the data streams that created by Citrix Memory Optimization.
After that restart this server this step only to make sure the changes that we made on the ProcessExclusionList registry. Than Activate Again the Citrix Memory Optimization.

Installing pnp ( PNP is not PerfParse ) at CentOs 5

2008-01-22T12:34:00.000+07:00

Because nagios not come with tools to generate chart, so I need another tools to this job.
I found several tools for this task such as perfparse, NagiosGrapher, nagiosstat, and pnp.
After try to install some of this tools I choose to use pnp. I use pnp because it's easy to install.
To install pnp first read the documentation then proceed with the installation step

./configure --sysconfdir=/etc/nagios --datadir=/usr/share/nagios/pnp --bindir=/usr/bin --localstatedir=/var/nagios

you will see the configuration summary

make all && make install

Then you finish with the installation.

Now we gonna edit our configuration files.

For the first step edit the nagios configuration file, at my system it is the nagios.cfg, edit the following lines
Now edit the command definition file at my system it's called commands.cfg, edit the process-service-perfdata definition
at the command-line section set the value to /usr/bin/perl /usr/local/nagios/libexec/process_perfdata.pl.

here the process-service-perfdata section at my commands.cfg

According to pnp documentation process_perfdata.pl can not start under ePN(embeded Perl Nagois), that's why we must put the perl full path.

This type of configuration is default mode. There are others type of configuration mode, they are Bulk Mode and Bulk Mode with NPCD.

Create 2 other files serviceextinfo.cfg and hostextinfo.cfg. Both file name must match with the file name at Extended host/service info definitions section in the nagios configuration file (see above).

to create both files use this command "touch serviceextinfo.cfg hostextinfo.cfg"

Then edit both file.Here the content of my serviceextinfo.cfg (this will monitor the CPULoad at my windows machine)

The service_description must be the same at your service configuration file.

And for the hostextinfo,cfg

At my system I also edit the config.php, which the configuration file for pnp, I only change the temp directory to /tmp/nagios

$conf['temp'] = /tmp/nagios

Stop the nagios service, and then use the nagios command with -v parameter to check if there are no errors at your configuration file.
If everything is ok then star tthe nagios service then you are done.
To check if your installation success, see at the RRD direcotry whether the rrd and xml files generated on that place.
I got a problem with SELinux feature, that casue the pnp can not read it's RRD dabatabase directory. I still not figure out how to
fix this, so for now I disabled SELinux on my system.

Nagios monitoring tools...

2008-01-21T18:45:00.000+07:00

Because the nature of my job as System Engineer, and also as Administrator for my division, which running 24x7 so I must know which computer that having sluggish performance, before the computer became useless in daily operational.
My division is a collaboration between Indonesia company and a Dutch based company..well they outsource some of their task to my division, including monitoring task, they use BMC Patrol for monitoring their customer environment.
BMC Patrol is a powerful tools,but is very expensive.Because I only need to monitoring my division environment, so I must use a cost free tools (because there is no way the management will permit me to buy a monitoring tools), and after googling i found a monitoring tools that called nagios.I like nagios because it a great tools with free of charge, and the most important it's open source.Nagios can monitor anything on your computer with the help of its plugin. There are lots of plugin for nagios, such as plugin to monitor mysql server, Citrix, Oracle, CPU, memory, etc. Well there are lots of plugin for nagios, so it's almost imposibble to mention then one by one. You can find nagios at their web www.nagios.org, there are documentation for that, and also you can use google to find help when you stuck with nagios.

But when you installing nagios from the source you must have lot of patient and read the documentation over and over again.
For me I use the rpm package from rpmforge, only need to run the yum command, then the nagios automatically installed on your system.
After you installed then you must configure the nagio configuration file, and what I like from linux is the configuration file use text, and not registry like the one you find a windows system.Because I use centos as the nagios server I use the guide from Max Hetrick at the centos wiki here the web http://wiki.centos.org/HowTos/Nagios. Because nagios not provide a graphic output so you need an add-on to generate chart, for this i use pnp(PNP is not PerfParse ), it's a great tools and quite easy to installed.

Because all the computer at my division ia a windows machine (except for the nagios server), i use the NSClient++ at the windows machine, and at the nagios server I use check_nt plugin. You can monitor all the counter you can find at windows performance counter. To see which counter available at your computer just use the perfmon snap-in. For start see this link http://nagios.sourceforge.net/docs/3_0/monitoring-windows.html.

Don't use Process Monitor at Windows 2000

2008-01-11T20:06:00.000+07:00

Yesterday, I try ProcMon at one of my customer server, that server is a Windows 2000 SP4 with Update Rollup 1, so I think the ProcMon should be running smoothly on that server, but after I start that application and click the Agree button , the server restart it self... it seems the server got crash and it took more than 10 minutes so that server finish it boot process. Thank god I try that outside office hour, if i do that while the customer still work..you can guess what kind of email i will got here... There should be a warning at the Process Monitor web , that this tool can cause crash on windows 2000.... btw I use this tool because it is recommended by MS at their technet web.... well that a story of the day ,,,

Enabling Cirix client Access at ISA 2004

2007-12-06T16:54:00.000+07:00

Few days ago i need to enable Citrix access at my client to their Citrix server at Singapore.
They use ISA 2004 as their firewall.
At ISA 2004 there already a template for ICA protocol, but the
problem is this template useless, i already try to use that, but internal network still can't access
the citrix server.
So as solution I create a "Custom ICA" protocol. Just use the ICA template from ISA 2004
as your reffences to create the Custom protocol, the only different is put the Port 1604/UDP at
Primary connection, rather then at secondary connection like at the template.

Here the different between the ISA template and the Custom

ICA Template from ISA 2004

Custom ICA Protocol

After you create that "Custom ICA" protocol, then create a new firewall policy, see the bellow picture asyour refference.

WinDbg and BSOD

2007-11-30T16:29:00.000+07:00

- Downloads Windows debugger from Microsoft Web, after that install that Application at your Computer
- Find where your Windows store your debugging information.
- To find out where your windows hide your Debugging info Right Click the "My Computer" Icon.
- Select Property then go to Advanced Tab.

- At the Startup and recovery Section click the Settings button.

- Now you can see where your Windows store it's Dump file.

- For the start menu Start -> All Programs -> Debugging Tools for Windows -> WinDbg

- Now Open the dump file, go to File -> Open Crash Dump, then navigate to directory where the dump file stored.

- After you Open that file you will see lot of info. You can find the cause of BSOD, see at the bottom.

- As you can see the cause of the BSOD on my server is a file called mfehidk.sys, which a processes belongin to McAffe AV ( and that sucks)
- For detailed debugging info you can use command !analize -v , at the commad field

Network Configuration File for RedHat/CentOS/Fedora

2007-10-28T00:36:00.000+07:00

Because I work with my Linux Server directly from terminal, No fancy GUI. So I edit the network configuration
directly to ifcfg-ethx file (x = NIC Index), the file name depend to your device name, for example my Linux Server
Only have 1 network card so the configuration will had name ifcfg-eth0.
The configuration file located at /etc/sysconfig/network-scripts directory.

Here the the network file configuration when assign static IP
DEVICE=eth0
BOOTPROTO=none #If DHCP, then change to yes
HWADDR=00:00:1C:0A:AC:60 #MAC Addr
ONBOOT=yes #Set active on boot
TYPE=Ethernet
NETWORK=192.168.1.0
NETMASK=255.255.255.0
IPADDR=192.168.1.10
USERCTL=no #Set Yes if you want te ordinary user change the Network configuratin
IPV6INIT=no
PEERDNS=yes
GATEWAY=192.168.1.254

Here for DHCP
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:00:1C:0A:AC:60
ONBOOT=yes
TYPE=Ethernet
#NETWORK=192.168.1.0
#NETMASK=255.255.255.0
#IPADDR=192.168.1.10
#USERCTL=no
DHCP_HOSTNAME=komputerku.rumahku.local
#IPV6INIT=no
#PEERDNS=yes
#GATEWAY=172.17.8.254

And here for DNS servers
nameserver: 192.168.1.1
nameserver: 192.168.1.2.

For the DNS server, you can edit the file resolv.conf, you can find that at /etc directory.

When you finished, then restart the Network service, you can use command "/sbin/service network restart"
or "/etc/init.d/network restart". You must have root privilege to run both those command.

Don't move Exchange Security Related Groups

2007-10-27T18:36:00.000+07:00

Few day ago, I got call from the Office, they told me that one of our client exchange server got problem.
The exchange services can not start. It took hours to start the server, and sometime they must unlpug the network cable, from server NIC (Yeah good idea). After I came, I see that their try to install the Exchange SP2,but the installation procceses always end up with error.
The person who in charge, told me that there are problem with connection to Domain Controller. After I see the Event viewer I see there are lot of event with Id 9157 with source MSExchangeSA. Here the details of the event

Event Type: Warning Event
Source: MSExchangeSA
Event Category: General
Event ID: 9157
Date: 10/27/2007
Time: 11:57:32 AM
User: N/A
Computer: [Server Name]
Description: Microsoft Exchange System Attendant does not have sufficient rights to read Exchange configuration objects in Active Directory. Wait for replication to complete and then check to make sure the computer account is a member of the "Exchange Domain Servers" security group.

For more information, click http://www.microsoft.com/contentredirect.asp.

Apparently the Microsoft Exchange System Attendant service failed to start. This service is the most important service used by Exchange Server.
Because this service perform the important task, such as DS Lookup and other important task. If this service failed to start at least 3 other services will failed to start

Here the Description for Microsoft Exchange System Attendant service:
Provides monitoring, maintenance, and Active Directory lookup services, for example, monitoring of services and connectors,defragmenting the Exchange store, and forwarding Active Directory lookups to a Global Catalog server.
If this service is stopped, monitoring, maintenance, and lookup services are unavailable.
If this service is disabled, any services that explicitly depend on it will fail to start.

After some search from eventid.net and Google, apparently the main cause of this event because two security that related to Exchange
(Exchange Enterprise Servers and Exchange Domain Servers) moved to other OU. Looks like MS hard coded the Exchange to search both Security Group at User container. After I move back both Exchange and Start the Microsoft Exchange System Attendant, the problem
solved.

2007-10-24T02:44:00.001+07:00

A Week before the final release, I donwload the rc version , and installed to my T61.

The first problem that I got with Gutsy is I need to set the SATA configuration to compatibility mode, instead AHCI.This make Vista run very slow. I still use windows because my job.

Beside that the Wireless NIC unstable, some time I can not change to other network.

Other than thoese 2 problems, Gutsy run well on my T61 , I hope there are solution for the AHCI problem. I hope.

2007-03-22T03:17:00.000+07:00

Because I using Putty to configure the Linux server at my office,
so I choose public-private key as authenticate method.
Here some step to configure your Linux environment so the key authentication method.

- First we must generate a public-private key pair using putty key generator, just click the Generator button,

and move your mouse along the blank area. Make sure the key type is SSH-2 RSA, for security reason.

- After you finish you will see the following window, after that insert your passphrase key, and key comment. And copy paste your public key to notepad, and safe that with name "authorized_keys" , and also click the "Save Public Key" button and "Save private key" button to save yours private key and yours public key. The public key and private key must in the same folder, so It can work.

- After you safe then copy the "authorized_keys" file to .ssh directory at your home folder on linux folder, if the directory not exists the create a new one, you can use pscp to copy from your local folder to the remote folder. I assumed that pscp apps already on your path.
pscp "c:Documents and Settings\ronaldo.ronaldo\keya\uthorized_keys" ronaldo@shiro.office.loc:/home/ronaldo/.ssh

- After the file copied to your home directory at your linux server, the final step is to connect to your linux server using your newly generated key here the command that I use to connect to my Linux server :

putty -i "c:Documents and Settings\ronaldo.ronaldo\key\my-privkey.ppk" shiro.office.loc -l ronaldo

Configure DHCP at Linux

2007-02-20T21:17:00.000+07:00

I create a dhcp server with Linux I use CentOS 4.3 , I use Linux one because the dhcp under win 2003 not work , It always fail when try to get authorize from the Active directory at Holland.
To start we must check whether dhcpd installed at your linux machine.
- after you sure the dhcpd installed on your machine
- then run "cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf" , this command will copy the example configuration file and replace the configuration file, this is ok because the original file contain nothing. just few lines of comment.
- after that edit the dhcpd.conf file, here the example of my configuration file :

ddns-update-style interim;
ignore client-updates;

subnet 192.168.1.0 netmask 255.255.255.0 {
# --- default gateway
option routers 192.168.1.254; #default-gateway
option subnet-mask 255.255.255.0; #netmask

Nature Strike Back.......

The last 2 days jakarta is more like venezia, this is cause by the great flood that came every 5 years, this flood cause by heavy rain for this past few days, but according to the weather guy this is only the beginning, because tomorrow heavy rain still going to happen at jakarta, also the ciliwung river blew up. But the major cause of this flood because people of jakarta never put respect to nature, every green area in jakarta always converted into mall, apartment, real estate, or skyscraper. For simple example kelapa gading , it was a swamp before converted into real estate, mall, and apartment. Also the habit of jakarta citizen that always littering on everywhere especially on the river... now it's time to change our behavior. because if we keep threat nature like this , the next flood will more worse that this .... so please Respect The Nature...

Euh............

Darn... why internet connection at this country very...very...very.. slow , because no no mater the connection type whether ADSL, Dial-up it's all the same . If I use speedy(ADSL) then the connection not reliable, if using dial-up then the connection very....very.. slow like a turtle. This image taken when I update my anti virus.. you see the speed .. it's shameful.

Should human race still exists on this planet ???

what human race do to this planet is nothing more than destruction, every day we can see the size of our rain forest reduce very...very fast, and the number of species also decreasing very fast, event some of the species already extinct. If the human race not do something about this in the end the species that will extinct is the human it self .. quite funny because the cause of human extinction is them self.
