There is always a group of people who have nothing to do with the server! I don't know who is violently cracking the company's ftp.

The log server keeps alarming and keeps trying to log in to ftp with user passwords, but it's not about you logging in. The password is complex enough to crack for a period of time. If there is a loophole, it depends on the conduct of those who do it. The key is that I am worried about my log server, ah, to keep recording these things. Looking uncomfortable affects your mood.

Dynamically view the log: (if you try more ip, you can disable access manually, of course, you can also write a ftp to prevent brute force cracking script. If you try too many times, iptables can be temporarily closed. )

Check out ip, Aliyun. You're kidding me. I don't know who's lying down. It is estimated that the connection will be made by * or other ways!

Write an acl to prohibit it first. Calm down. no, no, no.

Reflection: firewalls only allow companies to connect to ftp. What the heck is this? The company didn't build anything like that.

Is the local area network affected? Daoxing is not enough, what do you think?
