DNS, LDAP and JMS on Linux Part 1

There are several web servers which can be used on your Linux system but you need to choose the right one according to your requirement. In this regard the DNS web server will be the best fit for your Linux system.

Fortunately, users can use the DNS web server both for the public and private domains. You need to locate this server on DMZ because this server will need to be accessible from both the internet and LAN. You can also use the same name for second level domain on this web server. Now, you need to use the DNS web server for your Linux system for the best functionality.

As the service, DNS is important to operation of Internet and whenever you enter the www.some-domain.com in the Web browser, it is DNS, which takes www host name as well as translates that to IP address.

Without the DNS, you can get connected to Internet fine, however you will not go anywhere. Not till you keep the record of IP addresses of the resources that you access on Internet as well as use these in place of the host or domain names. Thus, when you visit the Web site, you are doing so by using website’s IP address although you specified the host & domain name in URL.

In background the computer fast queried the DNS server for getting IP address, which corresponds to Web site’s server & domain names. You now know why you need to specify 1 or 2 DNS server IP addresses in TCP or IP configuration on the desktop PC (and in resolv.conf file on the Linux system and TCP or IP properties in Network Control Panel on the Windows systems).

One “cannot connect” error will not necessarily indicate there is not the connection to destination server. There might well be and error might indicate the failure to “resolve” domain name to the IP address. I make use of open source Firefox browser on the Windows systems as status bar provides more of informational messages such as “Resolving host”, “Transferring data” and “Connecting to”, instead of generic “Opening page” with the IE. (It as well appears to render the pages faster than the IE.)
