Thanks to Nanyou, let me get the ida dynamic debugging, and it has been a long time ago. It seems that there is a problem with the source of the previous ubuntu. The ifconfig command has not been installed. Reinstalled the system and replaced it with ubuntu. Here we record the ida dynamic debugging process.
1. Ida dynamic debugging
1. First click on this folder 
2.
Many types, see which platform is the file, for example, I am here linux64, so upload that linux_server64 to my server, and then start running,
3. Open ida , Button to
borrow a network diagram, said concisely.
F9 starts to run, and it succeeds without error. If an error is reported, restart linux_server64 on the server side.
