Preface
This article mainly introduces how UFIDA U8 can achieve remote access from other places through the cpolar intranet penetration tool, making it easy to work remotely anytime and anywhere!
UFIDA U8 Cloud is a cloud ERP solution launched by UFIDA. Based on cloud computing technology, it provides enterprises with comprehensive enterprise resource management solutions, covering financial accounting, procurement management, sales management, production and manufacturing, human resources and other fields.
Easily work remotely anytime, anywhere! How does UFIDA U8 realize remote access through intranet penetration?
1. User needs
U8 cloud products support public cloud deployment and private independent deployment. It adopts the public cloud deployment model. For customers, the server does not require dedicated maintenance. It is unified and maintained by UFIDA engineers. Users can worry and rest assured. However, most customers are out of application. Considering the needs and other aspects, I still want to deploy the server on a private server I built myself and maintain it myself. Since the server is deployed independently for these customers, the following points need to be considered in the remote access solution:
1. You need to optimize your own network. The server's network condition should be as fast as possible and support access to multiple network types to meet the response speed issues of different regions, different network types, and connected servers;
2. The deployment should be as simple as possible, and do not spend too much time and labor costs on implementation and maintenance;
3. Since U8 cloud is an application system for internal enterprises, the security of remote access must be guaranteed, intranet penetration must be supported, and the server configuration should not be adjusted too much to avoid security risks to the server;
Faced with user requirements for access security, server security, access speed, etc., the Cpolar intranet penetration solution can be used. Cpolar is an intelligent networking product that can form a virtual LAN from different cities to realize remote data interconnection. Interoperability to solve the problem of interconnection between headquarters and branches
2. Installation and registration of Cpolar intranet penetration
After completing the U8c test and being able to log in correctly, we can move to the cpolar installation. The installation and registration of cpolar is simple and easy. We can find the "Download" button directly on cpolar's official website page (www.cpolar.com).
The author is using the Windows operating system, so I chose the Windows version to download.
After the Cpolar download is completed, unzip the downloaded compressed file and double-click the .msi file to automatically execute the installation program. Then just click "Next" to complete the installation.
Since cpolar will create an independent data tunnel for each user, supplemented by user passwords and token codes to ensure data security, we need to register users before using cpolar. The registration process is very simple. Just click "User Registration" in the upper right corner of the cpolar homepage and fill in the necessary information on the registration page to complete the registration.
2.1 Cpolar cloud settings
Since the data tunnel of the free version of cpolar is reset every 24 hours, I don’t want to reconnect every day, so I upgraded cpolar to the VIP version to create a data tunnel that can exist stably for a long time and facilitate access to the local Qchan website at any time.
Next, we set about penetrating the local Qchan page into the intranet for public Internet access. To achieve long-term stable intranet penetration, you need to first log in to cpolar's official website, find the "Reserve" button on the left side of the user's home page, and click to enter cpolar's data tunnel reservation page.
A public Internet address is generated here (which can also be regarded as the entrance of the data tunnel). Since this address is not connected to the local program output port at this time, it can also be regarded as a blank data tunnel.
On the reservation page, you can see many types of data tunnels that can be reserved. Here we select the "Reserve second-level subdomain name" field.
In the "Reserved second-level subdomain name" field, you need to make simple settings for several pieces of information, namely:
"Region" (the area where the server is located, just select the nearest one)
"Second-level domain name" (will eventually appear in the generated public Internet address as one of the identifiers of the network address)
"Description" (can be regarded as the name of this data tunnel) description, as long as it can be distinguished from other tunnels).
After completing these settings, you can click the "Reserve" button on the right to retain this data tunnel.
2.2 Cpolar Web UI local settings
After completing the settings of the cpolar cloud and retaining the blank data tunnel, we returned to the local cpolar client and connected the blank data tunnel generated by the cloud to the local test page so that we can access the local test on the public Internet. page.
Open and log in to the cpolar client locally (you can enter localhost:9200 in the browser to access it directly, or you can click the cpolar client shortcut in the start menu).
Click the "Create Tunnel" button under the "Tunnel Management" item on the left side of the client's main interface to enter the local tunnel creation page (if you want to create a temporary data tunnel that does not reset the address for 24 hours, you can set it directly here without cpolar The official website sets up a blank data tunnel).
On this page, you also need to make several information settings, which include:
Tunnel name – can be seen as cpolar’s local tunnel information annotation, as long as it is convenient for us to distinguish;
protocol – since the test page is a web page, the http protocol is selected;
local address – the local address is the output port number of the local website, and the default The output port is, so 82 is also filled in here;
domain name type – In this example, we have reserved a data tunnel for the second-level subdomain name in the cpolar cloud, so check "Second-level subdomain name" (if the reserved To customize the domain name, check Custom domain name), and fill in the reserved second-level subdomain name in the "Sub Domain" column on the next line, in this case "eXtplorerweb". If you plan to create a temporary data tunnel, just check "Random Domain Name" and let the cpolar client generate the network address on its own;
Region - The same as the information reserved on the cpolar cloud, we can fill it in according to the actual location of use;
After completing these settings, you can click the "Create" button at the bottom of the page to connect the blank data tunnel in the cpolar cloud with the local payment test page to generate a data tunnel that can access the local U8cloud page on the public Internet. After the intranet penetration data tunnel is generated, cpola will automatically jump to the "Tunnel List" page.
We can manage this data tunnel on the "Tunnel List" page under "Tunnel Management", including opening, closing or deleting this tunnel. We can also click the "Edit" button to get the most information about this data tunnel. to modify.
3. Public network access test
Access personnel install U8 Cloud client
Click "Add Application" and enter the public network address generated by cpolar on the U8 cloud server, and then click search to see the U8 cloud application icon.
Copy the public address and paste it into the browser below.
Click the U8 cloud icon to open the login interface.
