The Presence of the Running Machine on the Internet

Everything has a start, and has an end.

Deploying a server over the Internet is different from setting up a local server without being revealed to outside people. For a server to be unknown on the Internet by fully-qualified hostname, it requires some registration processes. Furthermore, since the server is known to the public, some security measures should have been taken to avoid the abuse of the server.

This package includes basic elements for network operation, for example, DNS, FTP, firewall, backup storage server, VPN (Virtual Private Network) and Email .

We start from the introduction on Domain name registration with the following diagram:

1. Purchase domain name from the “vendor for domain name registration”

The “Domain Name Registration Vendor” usually will provide a Web interface for you to query your desired domain name. You may find some of the domain names you like have been acquired by other people. It is necessary for you need to find a domain name that is not being occupied. And then make the purchase of the domain name from the “Domain Name Registration Vendor” to complete this step.

2. Purchase Internet bandwidth and obtain “static” IP addresses from your local ISP (internet service provider).

Usually, the ISP will give you a set of IP addresses that may include a list of public IP addresses, the netmask, and the default Gateway. This IP information will be used when you install the software and configure your server. You shall keep the information in a safe place once you obtain that from your ISP.

3. Find a legitimate “DNS host provider”

It is to host your domain name (which you get from step 2) and the associated static IP address (which you get from step 3) record so that everybody on Internet can use your domain name to reach your server. Usually, the “DNS host provider” will provide a Web interface to allow you to input your domain name and the mapped IP address record into their hosted server. This step is completed after you have entered the data into the web page.

4. Update the record at the “Domain Name Registration Vendor” server with the IP addresses of the “DNS host provider”.

At this step, you need to access the website provided by “Domain Name Registration Vendor”. If you do not know the DNS server’s IP addresses of your “DNS host provider”, you can do as follows at your Windows command prompt (the command prompt is reached through Start > Run > cmd), issue the command

　　C:\>nslookup DNS-server- name-from-your-provider

The system will respond with the IP address of your “DNS host provider”. Usually, you need to find two IP addresses of the two DNS servers provided by “DNS host provider” (one is called primary DNS host server, the other is secondary DNS host server). The two IP addresses will be entered into the record in the place of “Domain Name Registration Vendor”. We suggest using primary DNS server and secondary server from different places. The Azblink server package also provides DNS server. But to allow people all over the world can query your domain, you should have your domain name placed in different DNS servers to alleviate the load.

5. Wait until it is in effect.

In general, it needs 24 hours to 72 hours to have your domain name record of the server populated across the world so that people can use domain name to access your server.
Those are the general steps as long as you want to have your own private server(s) on Internet.

Connection Failure Solving

Something wrong with your network? You completed the installation, but unfortunately you failed to get through, that really make us depressed. Many problems will cause failure, thus at such moments, we may feel perplexed and have no idea about how to deal with it. It is for this reason that we provide integrated test items and solutions to ensure your network works smoothly.


1. Check if there is something wrong with your network configuration, your clinet PCs are
　connected in same network with the host? The mean is all ones is in the same subnet
　in intranet (ex: 172.16.9.0/24).

　a. You can open Windows command prompt at your PC, enter ipconfig/release to release current IP, and then
　　 host.

　b. If it is not in the same subnet (ex: 172.16.9.0/24), please confirm if there is something wrong with your
　　configuration, or there is other DHCP server.

2. Network setup fault?
　Please comfirm Internet or PPPoE item in System >> Network. ex: DNS, default gateway

3. Does the network cable loose contact?
　Pull it out and then plug in

4. Is the network cable broken?
　You can use cable tester to test it, or just replace it.

5. When the network cable outdoors, please check that the cable efflorescence that its maybe
　the cable bedisconnect or short even damage the machine.
　Please maintain equipment periodically

6. Is the cable too long?
　Signal will be weak and make us unable to access network. It is suggested that you set a repeater
　( ex: HUB, switch, repeater, bridge.) every 30-50 meters to avoid attenuation.

7. Do network card and transport port work normally?
　a. We can judge it from the indicator light.

　b. If it looses contact when you are at thunder and Lightning day, although the light can glitter normally,
　　your network card maybe already got short-circuited. We suggest you change network card.

　c. If the NIC card is onboard and seems no any unusual, but you cant access the network, we doubt that
　　your network card may be broken. Please enter the BIOS, and disable that startup
　built-in network card. Then add-on a new NIC card.

8. Does the port of hub work normally?
　Judge from the indicator light

9. If the system has two Ethernet ports, by switch plugging the Ethernet cable into the
　eth0 and eth1 ports, you can confirm what port is eth0 or is eth1. The cable connected
　to internet should connect to eth0. The cable connect to LAN should connect to eth1.

　Pull network cable out, we can check if eth0 or eth1 turns out on the screen.

10.Before host installation, you must check slot is outdating or oxidation
　 you can reinstall hardware like mainboard, NIC card etc, that it is be deoxidized

11. Can system support the NIC card?

　a. After system been installed, we login in the console mode by using account: reset and password: root123
　　on the host side. Select option 6. View Current Active Values to check if system can detect the NIC card.

　b. If the system cant find NIC card, it maybe because the system didnt detect the card when installation,
　　or system doesnt support it. We just re-install the system, or replace with a new card.

　c. If the NIC card is onboard, please enter the BIOS, and disable that startup built-in network card. Then
　　add-on a new NIC card.

　d. We suggest you use cards consistent with Relteck, such as 8139, for others you can check the network
　　card support list.

12.After system installation been completed, if some hardware changes, we strongly suggest
　 you re-install your system. Several minutes can avoid many mistakes which can not be 
　 expected.

13. Please check if your network bill has been paid or not.
　  If network be broken, contact your ISP )

Hardware Requirement

X86-compliant hardware

Nowadays, this kind of application would not need computation power like large-scaled scientific research projects. Most of the constraints come from input/output operations from one device to another device. So, instead of choosing powerful machines, we suggest using reliable ones.

Hardware with Ethernet interface(s):

If you would like to put the server inside a firewall, it only needs one Ethernet interface on that machine. To use firewall on the same machine, it needs two Ethernet interfaces.

Uninterrupted Power System

For the sake of system stability, we recommend to equip the server with mini UPS (Uninterrupted Power System) to protect the server from sudden power outage. Power outage or power surge would damage some components. To protect the investment, it is a good choice to have UPS ready.

Switch/Hub

Switch or hub bridges traffic from each host and each host is responsible for collision detection and retransmission. If your network environment has more PCs that can not be plugged into one hub or switch, an additional Ethernet switch shall be used to expand the connectivity.

Wireless Router (Recommended, but not necessary)

Wireless router or wireless access point becomes popular in office and home environment. This device can deliver data just like a wired Ethernet, and provide an efficient solution for people with mobile computers. It should be noticed to deploy wireless access point by avoiding IP address conflict.
