Remotely access local hard disk files from the public network [intranet penetration]

With the popularity of the cloud concept, many companies use cloud storage technology to save office files. At the same time, many individual users also feel the convenience brought by cloud storage, making the concept of cloud storage unparalleled for a while. Due to the sensitivity of data, frequent outbreaks of cloud storage data leakage incidents and expensive cloud space rental fees, many companies have given up public cloud storage. However, the benefits of cloud storage for data and data are difficult to give up, making the private cloud model gradually popular. The price of small cloud storage devices represented by Synology NAS has been rising all the way, which is the best proof. In fact, it is not necessary to purchase expensive kits for medium-scale data cloud storage. Just a few simple software can turn our personal computer into a convenient cloud data search and download device, thus Great savings. Today we will introduce to you how to use cpolar and Everything to build a low-cost and lightweight search and download platform.

First of all, let's understand the functions of these two software. Everything is essentially a small but powerful file searcher. We can search for files on the local computer like a search engine, and the software also provides simple http services and specified port output functions. And cpolar is a powerful intranet penetration software, which can establish and maintain multiple data tunnels of different protocols, such as http, https, tcp, ftp, etc. By combining the two, one of the core functions of cloud storage can be realized, which is to retrieve data files located on intranet devices in a public Internet environment. Of course, due to the lack of functions of the Everything software, it is temporarily impossible to read online and upload files back to the LAN device.

To build this minimalist cloud storage platform, we first need to download Everything and Cpolar. After the software installer is downloaded, double-click the installer to install it by itself.

After the software installation is complete, we first open Everything and set the output port of the software. In the task bar above the main interface of Everything, find the "Tools" option, and then click "Options" in the drop-down menu to find the settings about http.

In the http setting content, we first check "Enable http server", and then set the http server port. There are not many requirements for setting the server port, as long as it is an unoccupied port; then you need to set the http server user name and password, which can be set according to your preferences; finally, for our practical use, it is best Also check "Allow http file download", otherwise the files searched remotely will not be able to be obtained. After completing the above settings, you can click the "OK" button below to complete the http settings of the Everything software.

When saving the http settings of the Everything software, the system security prompt may pop up, here we click "Allow Access".

After completing the setting of Everything, we enter into the setting of cpolar. Since we don't want the hard-working setting of the Everything query and download tunnel to be used only temporarily, it is necessary to establish a data tunnel that can be accessed stably for a long time.

First, we enter the official website of cpolar (you can enter cpolar in the search bar of the search engine to find the official website, or you can find the shortcut key directly connected to the official website in the Web-UI interface of cpolar)

The first is "region", here we can fill in according to the actual use, in this example we choose China VIP; then "secondary domain name", here we can fill in any information such as company name, department name, project name, etc. However, the reserved second-level domain name will be displayed on the final data tunnel address URL, so it is best not to fill it indiscriminately. Here we fill in Everything; the last is the "Description" field, which is mainly for users to distinguish this second-level domain name from other second-level domain names, so you can fill in content that is easy to identify, here we fill in "remote call data".

After filling in these contents, you can click the "Reserve" button on the right. Create a blank data tunnel with no tunnel entry and exit set.

After the blank data tunnel is set up, we can go back to the cpolar client of the local computer and set the entrance and exit for this blank data tunnel. Open the cpolar Web-UI interface on the local computer, find the "Create Tunnel" under the "Tunnel Management" item on the left side of the main interface, fill in the second-level sub-domain information we reserved into the tunnel to be created, and at the same time Also set the entry and exit for the blank data tunnel.

First, we enter the "Tunnel Name". Since this field will not be displayed outside, we can choose it by ourselves. Here we enter "Remote Data Transfer"; for the "Protocol" and "Port" fields, select "http" and "Port" respectively. "82" (port 82 is previously set for Everything, and it is also the exit of the data tunnel, which needs to be filled in according to the actual set port number); in the next "domain name type" field, we select "secondary subdomain name", After selecting the second-level sub-domain name, the "Sub Domain" column will appear below, where we fill in the second-level sub-domain name reserved on the cpolar official website (that is, which reserved data tunnel is selected); the subsequent "Region" field, It can be filled in according to the actual usage area, here we choose "China VIP". After completing these settings, you can click the "Create" button below to generate an intranet penetration data tunnel that can connect to the local Everything software from the public Internet.

At this point, we can click the "Online Tunnel List" page under the "Status" item on the left side of the cpolar main interface to find the entrance of this data tunnel, which is the public Internet address, so that we can easily query and download the local computer on computers outside the LAN. documents on the .

It can be seen from the above introduction that it is not complicated to establish a data platform that can remotely call and download local data by itself, which is very suitable for small businesses and private use. Of course, the establishment of such a remote data call platform is only one application scenario of cpolar's powerful functions. The intranet penetration data tunnel established by cpolar can be used in conjunction with other software, and there are more application scenarios. If you have any questions about the use of cpolar, please contact us, we will provide you with assistance within our ability. Of course, you are also welcome to join the VIP official group of cpolar to explore the unlimited potential of cpolar together.
