I am outlining the steps for my server, ie. CentOs 5.2 with Apache 2.2

• wget http://dl.atrpms.net/all/mod_limitipconn-0.23-4.el5.x86_64.rpm
• rpm -i mod_limitipconn-0.23-4.el5.x86_64.rpm
• vi /etc/http/modules/ipconn.conf
  

  Add following to the content of ipconn.conf
  # LimitIPConn module limits the number of connection to apache
  # per IP address. This helps in limiting the simultaneous downloads and will help
  # prevent slow users from blocking your servers.
  #
  <IfModule prefork.c>
  LoadModule limitipconn_module modules/mod_limitipconn.so
  </IfModule>

• Make sure ‘ExtendedStatus‘ is ON in /etc/httpd/conf/httpd.conf
• You will have to configure the module for each of your virtual host that you need to implement the limitip for.
  

  <IfModule mod_limitipconn.c>
  <Location /forums>
  MaxConnPerIP 3
  # exempting images from the connection limit is often a good
  # idea if your web page has lots of inline images, since these
  # pages often generate a flurry of concurrent image requests
  NoIPLimit image/*
  </Location>
  <Location /video>
  MaxConnPerIP 1
  # In this case, all MIME types other than audio/mpeg and video*
  # are exempt from the limit check
  OnlyIPLimit audio/mpeg video
  </Location>
  </IfModule>

• Save the config file and test the new configuration “/etc/init.d/httpd configtest”. If you get “Syntax OK”, then all you need to do is restart the server and you are good to go.

This is a brief guide on how I got mod_limitipconn working on my server. If you have any questions, please feel free to post in comment and I will try to answer your questions.

1. start -> run -> Type “msconfig” -> click on ok
2. Check the box selective startup
3. Under selective start up uncheck the 1,2 and the 4 options
4. Click on the services tab
5. Check hide all microsoft services
6. Click on disable all
7. Click on apply and ok
8. When asked, restart the computer
9. Wait for restart to complete and then log on to administrator account
10. Start -> Run -> Type “msiexec.exe /unregister” ->  click on ok
11. Start -> run -> Type “msiexec.exe /regserver” -> click on ok
12. Now insert the disc and install the office software

Hope this helps you in case if you encountered an error while installing Microsoft office.

It’s very easy to sync up the time in Linux/Unix. Issue the following command as ‘root’ to update the time.

ntpdate pool.ntp.org

To automate this time update, you can set up a cron job to run once every week.

Then I found that in the lower left corner, there’s a box with “Host Summary”. You have to add your nameservers entry in that box first. So click on “Add” besides “Host Summary” and it will present you another dialog where you can enter your subdomain and the ip address to point to your server. Once you have added your nameservers in Host Summary, then you can click on “Manage” besides “NameServers” and add your nameservers ns1.xxxx.com and ns2.xxxx.com there and Godaddy will happily accept it!!

Hope this saves you your time and help you avoid pulling your hair!!!

Google Error - This site may harm your computer

As you see in above screenshot, I saved the snapshot of the “yahoo” search keyword on google and all sites were reported as malware sites and when you click on any urls, it would redirect to a page warning you of that site. This is ridiculous and it is giving badname of your site to your visitors. Google has got no right to do so.

Save the following to /disk3/backup_exclude. Essentially, these are the files/folders you do not wish to backup using rsync.

/disk3/
/bin/
/boot/
/dev/
/lib/
/lost+found/
/mnt/
/opt/
/proc/
/sbin/
/sys/
/tmp/
/usr/
/var/log/
/var/spool/
/var/lib/php4/
/var/lib/mysql/

- Install Sun ODF Plugin for Microsoft Office.
- Open ODT document using File > Open, or by double-clicking the ODT file and when prompted for the application to open it with, choose Word.

Basically what this error is trying to mention that there is an issue with your php_openssl.dll and a possible mismatch with other depending libraries. To resolve this, follow the below steps:

1. Rename ‘ssleay32.dll’ and ‘libeay32.dll’ in c:\windows\system32 to ‘ssleay32.dll.old’ and ‘libeay32.dll.old’ respectively.

2. Copy ‘ssleay32.dll’ and ‘libeay32.dll’ from your PHP folder to the system32.

3. Restart the apache webserver.

This should get your problem sorted!!

My System setup is:

• Ubuntu 8.10
• Eclipse Ganymede (3.4) with CDT

Follow the steps to get black background with white foreground for source code editing part of eclipse.

1. Select Window -> Preferences -> C/C++ (language editor you need to change for) -> Editor. In the Appearance color options change the following
   • Matching brackets highlight (Color #FFA500)
   • Inactive code highlight (Color #302E2E)
   • Completion Proposal background (Color #000000)
   • Completion Proposal foreground (Color #FFFFFF)
   • Parameter Hint Background (Color #000000)
   • Parameter Hint Foreground (Color #FFFFFF)
   • Source Hover Background (Color #F5F5B5)
2. Select Window -> Preferences -> C/C++ (language editor you need to change for) -> Editor -> Syntax Coloring
   • In the Code, change all the ones with black color to white and vice versa and leave the rest as they are.

This will give you the colors you want. I know its tedious but that’s the only way to do it at present.
