IPtables and binlog

First check the kali virtual machine ip address 192.168.106.137

then nmap scan ip on windows
thiscan scan normally

Then configure port rejection on kaliThen use this to deny windows access

At this time, the scan found that the nmap status is closed

kali rejects nmap scanning through IPtable

binlog

binlog is closed by default

┌──(rootkali)-[~]
└─# vim /etc/mysql/mariadb.conf.d/50-server.cnf
Insert log-bin=mysql-bin statement
After restartThe binlog function is turned on

myAfter inserting it and restarting it, the binlog is not on and I don't know why...
View latest logs in mysql:
MariaDB [(none)]> show master logs;

MariaDB [(none)]> show binlog events in ‘mysqlbin.000001’\G

Create hjw library and table and insert some data:
First full backup:
┌──(rootkali)-[/tmp]
└─# mysqldump -uroot-proot -B -F -x --master-data=2 hjw|gzip >/tmp/hjwlog

Accidentally deleted the database by carelessness
Fortunately, there is a binlog backup
Avoid deleting and copying the latest files:
┌──(rootkali)-[/var/lib/mysql]
└─# cp -v mysqlbin.000012 /tmp

To avoid subsequent data flushing into logs:
MariaDB [mysql]> flush logs;

mysql opens the backup file
┌──(rootkali)-[/tmp]
└─# mysql -uroot -proot < hjwlog

At this time, the hjw database is restored, but it is not complete, so the file 000012 is used.
Edit the file 000012 to delete the data after drop and redirect it to mysqlbin
At this time, the data is completely restored
