Securing your web server is very important than the security of other computers on the network, because you can make other computers invisible on the internet using the “stealth mode” feature available on many firewalls. But the same cannot be done on the web server as it is meant for the complete public access. And the “public” might include beginner level users trying to curiously explore every nook and corner of you website and advanced hackers intentionally trying to find vulnerabilities on your website. And directory listing can be a boon for such people to start looking for juicy information.Continue Reading…
PHP can be useful when used in conjunction with html. Even if you don’t plan create full blown dynamic pages certain functions like server side includes can help you repeat the code less for commonly used things like menus and advertisements. But it can be irritating to end the file with a .php extension just because you’ve added a snippet of PHP code. Also some people say that pages with a .html extension rank more in search engines when compared to .php. I don’t know how far its true and I’ll leave it in your hands to experiment.
In this article I’ll focus on the things needed to be done for html to be parsed by the server. (More about this word later)Continue Reading…
Web Designing can be fun and interesting. Using the current cutting edge of web programming courtesy HTML5, CSS3 and jquery a beginner can easily create mind blowing web templates that look cool and refreshing. But all the hours of work to decorate the face of your site is wasted if the user encounters a bland looking error page containing technical jargon that leaves visitors scratching their heads. So custom error pages are the order of the day!!!Continue Reading…
The vmware virtual network editor can be of immense help for experts who want to tweak each and every component in their virtual network. Unfortunately it won’t get installed on your system when you install VMware player but fortunately copying it manually is not so difficult. The article Components of VMware Network contains instructions on copying vmnetcfg.exe.Continue Reading…
VMware player is a boon for people who have a single computer but want to learn networking from the comfort of their couch. In this article I’ll brief about the components of the VMware network which will help you in designing your own virtual network.
Virtual Network Adapters
On the host machine (physical PC) where VMware player is installed two network adapters are created VMware Virtual Ethernet Adapter for VMNet1 (used for Host-Only networking) and VMware Virtual Ethernet Adapter for VMNet8 (used for NAT).
In this post I’ll be briefing about the various services used by vmware player. If any of these services are not running you’ll experience problems accessing certain features of VMware player.
- VMware Authorization Service:- This service is used by virtual machines when they are “powered on” to access information. If this service is not running you’ll receive the error “Error while powering on: The VMware Authorization Service is not running.”
- VMware DHCP Service:- This service acts as a DHCP (Dynamic Host Configuration Protocol) server when NAT or Host-Only Networking configurations are used. It automatically assigns IP addresses to all the virtual machine adapters.
- VMware NAT Service:- When NAT (Network Address Translation) type of networking is selected this service is used.
- VMware USB Arbitration Service:- Plugging USB devices into the host computer shows a message box in the virtual machine. This service is used to connect USB devices to the Virtual Machine.
If any of these services are stopped you can bring up the run window [windows key] +R type “services.msc” (without quotes) and manually start these services.
