Echovnc
In fact, echovnc is not used yet. It may be because there are limits on the software provided by the website. You need to renew and pay for the software before you can complete the service! I think the delay will be extended with lag ....
Why?
1. echovnc is like UltraVNC with server and viewer.
2. The echoserver is like the one that explains how TeamViewer works on the server!
3. instantvnc is interesting. It is like TeamViewer quicksupport. It can be provided to the user so that the user can access the client without the need of security or configuration. The interesting part of this program is that you can change the Setting Value and display when you hold down Shift verification! (It is set to the server opened in the internal region of the echovnc Company)
Generally, UltraVNC is .. (please pay attention to the direction of the arrow)
Viewer --> render control --> Server
Echovnc is ..
Viewer --> echoserver <-- Server
Viewer --> echoserver <-- instantvnc
Only when the echoserver implements authentication and password management, it still needs to provide real IP addresses before it can be transferred to the attacker's terminal through NAT or fire protection.
It is said that, like TeamViewer and supportsmith, both the control end and the control end are used to bypass third-party servers to implement the bypass-to-penetration function. Both firewall and Nat are not suitable for outgoing ports and IP addresses...
Echovnc has very few teaching courses, but it is easy to know @ _ @ even if you are playing for multiple times @_@
Some people may find mixed passwords.
After installing the echoserver, you can set public and private when setting passwords between group and user ..
These two types of words are "public" and "private"
Conclusion:
Today, the manager has three engineering regions: A, B, and C.
In the settings, a group will be set to set public passwords for customers to use!
A, B, and C respectively set private keys for the user to select the group of the customer.
In this way, the customer can only upload data to the echoserver, while only three engineering teams of ABC can transfer data to the customer.
(If more than one customer volume exists, the customer is not afraid of unauthorized access to other customer regions, you don't have to worry about it. If you have mastered the customer's secret, you can try again later ~)

Of course, if only a single set of public passwords is set for a single transaction, the transaction can be transferred to the controlled end. As long as the password is kept confidential, we are not afraid that the controlled terminal will be under external control ~

Echovnc does not need echoserver, it can also be used,
The configured echoserver is the server opened by Alibaba Cloud on the Elastic Compute Service (echovnc). We recommend that you set the name and password of the Elastic Compute Service (echoserver ~ The name should be set to be easy to find (there are at least 30 people above). The password should be free from others who accidentally clicked on you, so they can gain control...

Echovnc is compatible with UltraVNC, that is, you can use echovnc to connect UltraVNC to each other, or multiple people can control the same host!

However, it is suggested that when UltraVNC or echovnc is deployed,
Please refer to any set in different projects ~ Otherwise, it will be based on the last security!

No matter what the problem with UltraVNC is, you just need to grasp a critical point, "Can you ping the IP address of the opposite end of the control"? If you can, it will be okay, if the peer IP address is a temporary IP address, if the IP address cannot be pinged, You need to copy the NAT addon provided by the official website or comment on the comment of the second mark above.

Recently, we connected to a set of similar software supportsmith, which is also the terminal-Assisted Software that penetrate the fire-proof environment. It is also freeware.
I just gave it a try. Similar to TeamViewer, you can use TeamViewer to find out if you are interested!
Bottom site: http://www.supportsmith.com/Download.aspx
However, its server seems to require money, not free of charge.
Supportsmith's server is free of money --"
The server end of TeamViewer also needs money and does not provide any renewal points...
In fact, these two products are intended for use, and TeamViewer will be easier to use than others!
It is a pity that TeamViewer is the problem of having to solve the problem in the current business. If it cannot be met, refill the system to solve it --"
Supportsmith may not be fully developed yet ~ QQ is good for the exam"

Net Control 2
Recently, I also found another example-Net Control 2. It seems that it can be used in classrooms (multi-person environments) for interaction between teachers and students, if you have any interests, you can check them out.
