To To 1. It's very simple. After setting the firewall to set the root user's password incorrectly for 3 times, the user cannot log in again within 24 hours, so not only others cannot log in, but even those who know the password cannot log in. 2. Close the ssh port, use vnc directly, if you want to use it, open ssh in vnc 3. Close the ssh process. Similarly, just enter vnc when it is used, so you don’t need to modify the port 4. Close the ssh port and connect to the 127.0.0.1 ssh port through a software agent that can be crawled 5. Forward the ssh port to another machine of its own, as a honeypot to collect passwords 6. The ssh port load balance is forwarded to neighboring machines on other network segments, even if the password is scanned out, the machine is safe, harming others and benefiting oneself. 7. friendship mjj supplement <br>

Netizens reply: To To Which is your step or choice? Look at Article 5. This is called "being a firewall"? I didn't see any strategic judgment. This is not clearly the dream of Dr. Zhao, who has a weak language foundation.
Netizen reply: To To This is too much trouble for you, it's okay to find something to do for yourself. It is enough to change the port plus the key plus the specified ip
Netizen reply: To To Close the password login, use the key. Then add a fail2ban, take it away without thanks.
Netizens reply: To To Simply change the port of sshd, this scan software is stupid, so I feel dizzy,
Netizen Reply: To To Nothing to look for, just turn off the password for honeymoon login, and I have never changed the port
Netizen reply: To To As for, what a precious machine. The port has also been changed before. Now I don’t even bother to change the port for a long time. Most machines still use the same password.
Netizens reply: To To I have tested it, if the port is not changed, the sshd is violently tested, the cpu will rise, After changing the port, the cpu doesn’t respond,
Netizen reply: To To I changed the SSH port and disabled root login. Su
Netizen Reply: To To Why is it so troublesome Directly strong the password, you scan it slowly!

Netizens reply: To To Poweroff is safe, since it is a waste of dust, then shutting down is the best choice.
Netizens reply: To To aptinstall-yfail2ban Relieve all your worries Except for password 12345

Netizen reply: To To Quote: 88232128 published in 2020-9-2412:43 What is the operation of changing vnc, vnc can not also blast
Netizens reply: To To The last one is a few layers of forwarding. If you are on the 7th layer, it is not that you are scanning others, and you will be titled.
