It's all about ports.

The company has moved over the past few days, so the busy blog has not been updated for a long time. The key is that there are no technical things and there is no idea what to write.

From Thursday to Sunday, we have been implementing products on the client side. The whole process is naturally interesting. The most important thing for me is to recognize the importance of flexible programming.

Our program requires several communication ports, one of which is 1433 used to connect to the sqlserver database. Many customers have closed this port for security purposes, however, in the configuration of our program, we cannot configure a new port. Therefore, the Administrator had to enable the port through coordination, and the system was running normally.

In the past, I often ignored this small configuration during processing procedures, which resulted in obstacles in implementation. In the past, I said that if a program is good or not, it depends on whether the configuration is good or not, and whether the configuration is flexible or not, there is a loss here.
