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.

Basic Web Setting

After the system installation be finished, take the CD out, reboot the machine, and then start the basic network setting for the system.

There are two modes to configure the host, one is console mode on the local host, and the other is Web interface mode on Client. You can choose the one you like or just by the network environment of that time.

Console Mode --- configure on local host

A. Input account and password to login into console configuration interface.

　login：reset
　Password：root123

B. You will see 7 options after login in

　1. IP Address：192.168.19.185
　2. Netmask：255.255.255.0
　3. Default Gateway：192.168.19.1
　4. Save and Reboot
　5. Reset to CD setting (DHCP) and Reboot
　6. View Current Active Values
　7. Exit without Saveing Changes

C. Is there any fixed ip ready for configuration?

　 Yes, type fixed IP address, Netmask and Default Gateway into option 1.2.3. severally. You can use up
　　and down arrow to choose the option who needs edit, and then press enter to configure. After option 1.2.3
　　be correctly configured, you can use option 4 to save these changes and reboot the machine. (If you have
　　no idea about the Netmask and Default Gateway, you can just refer to the Completion List provided by your
　　ISP.)

　 No, if there is a DHCP server providing the IP assignment services in your network, you can just use option6
　　to check the IP address assigned by the system. After checking eth0, please write down the IP address, and
　　remember to use option 7 to quit the Console interface.

D. By the IP address you set or the one obtained from DHCP, you can view the configuration page of the
　　 system host via Web browser on remote Client.

※ DHCP server exists in your network, but if you find eth0 shown as IP 1.2.3.4 when you check current system value, please check if your network cables plug into wrong place (eh0 and eth1 may been exchanged), or if there are some problems on other equipments. (Refer to Q&A in the manual)


Web interface Mode --- configure at sub-network

A. Is the host, which you installed system on, connected by other hosts?

　 Yes, please confirm the host is the only DHCP sever (that is to say the network should not have other
　　DHCP servers, e.g. IP distributor), and then start from C.

　 No, please complete basic network configuration according to B’s instruction.

B. A network cable makes host’s eth1 port and the Hub connected. And use another cable to connect to
　　Hub, let the other end of this cable link to a common Client computer.

C. Choose one Client computer from the sub-network which connected to the system host.

D. Open command prompt on the Client (suppose it’s a Windows machine), type “ipconfig” and then press
　“Enter” button, check whether the Default Gateway is 172.16.9.1 or not?

　 Yes, just close the command prompt, enter into next step.

　 No, type “ipconfig/release” to release the old IP in your computer, and then type “ipconfig/renew” to get
　　new assigned IP.
　　(If you are still unable to obtain new IP, please check if the network has other DHCP sever or not, or maybe
　　TCP/IP of this Client does not use the mode of “Obtain an IP Address Automatically”.)

E. Open your Browser, and type http://172.16.9.1 at the address bar to link. When you visit the page at the
　　first time, you will see 4 items;

　　Host Name：Please set Host Name for this host.
　　Admin Password：Default password is admin123.
　　New Admin Password：Please set new password.
　　Confirm Password：Please confirm your new password.

F. After you enter into system page, go to System>>Network, choose Internet or PPPoE depending on the
　situation.

　 Choose Internet. At the Internet Interface, mostly, you should set the values for IP address / Netmask /
　　Default Gateway and then submit, restart your machine and you will find it already connected to Internet.

　 Choose PPPoE. If you use PPPoE, remember to check the checkbox of “Turn on PPPoE”. Fill in the account
　　and password provided by ISP and submit, reboot your computer, then you can connect to the network.
　　(Please refer to the sections of Configuration and Q&A in Quick Installation Guide if you have any questions.)

Extract

The storage server is to provide the secondary storage for your data. Once the main copy of the data on your host is damaged, at least, you still have a copy of the data on the storage server. The following is to introduce how to retrieve the historical data from the storage server.

Select the data to restore

As we mention earlier, the storage server not only performs data backup on the folders of the other servers, but also has the backup for each user’s home directory. To extract data, you need to specify where the source of data is so that the storage server can restore the associated data accordingly.

After the source of data is specified, press “Continue” button will bring you into more detailed criteria to specify the data to restore.

Criteria/View

Once you select the source of the data you would like to retrieve from the backup server, more detailed information is needed. At first, you have to specify the date so that the storage server can extract the data at that date. Data is entered in the format of  YYYY-MM-DD (for example, 2005-03-22. It stands for March 22nd in the year 2005). After the date is entered, the following 3 methods are provided for you to look for the exact copy that you are trying to find:

-extract data on the given date above
The option will give you the snapshot of the data on 0:00 AM on the data YYYY-MM-DD specified above. 

-extract all version of the week associated with the given date
As mentioned previously, incremental backup is performed during weekdays and whole backup is done on Sunday. The option is to extract all the versions of data since its basis copy while whole backup is performed. It computes all the differences and restores them by putting them in the directory “ALL_DIFF_VERSIONS” by adding time stamp in the original filenames.

-extract snapshot of data of multiple days
This option allows you to specify a short range of days from the date you enter above so that the snapshot of the data on 0:00AM on each day can be extracted.

The data extraction process could take quite long time if the amount of data is quite large. If you know there are a lot of files in a specific remote folder, you might try to use different “share names” on Windows and perform backup individually. This can improve the efficiency of the extraction process to avoid extracting the data you do not need.

As for accessing the restored data, you need to issue the command from Windows like \\sHost\loginId . Where “sHost” stands for the name of the storage server, that is recognized by Windows system, or you can just use IP address for it. “loginId” is the login ID that you are using to login to the storage server. After you login successfully, just go to the directory “tmp”. Under tmp directory, you will find out the data extracted for specific date over there.

Virus Scan on Storage and Backup Server

And you can press “Virus Scan” button to check if there is any known virus on the restored files. The Storage server will remove those infected files but will keep the original files. So, each user needs to carefully watch those files if they are infected by virus.

Example: How to access the extracted data

Let’s look at the following example about how to access the extracted data on Backup and Storage server. You can use \\ipAddress\account or \\hostName\account in Windows command prompt or the top panel of Windows file browser. As indicated in the following diagram, we use \\192.168.19.185\test to connect to the server (the server’s IP address is 192.168.19.185). After issuing that request, a login prompt pops up and ask you to input the password.

At this moment, you just type the password for “test” account. If the password is correct, the content of file folder for the account “test” on the Storage and Backup server will be displayed. The extracted data will be found under “tmp” folder.



Or using below



Access your Backup and Storage server as indicated above.



The login menu pops up to ask your password. After that, you will find the files and folders.
