Linux Server Security Check script

#说明: Everyone usually on the Linux server security is mainly to the system user check, login server IP check, and firewall status check!

1. The correct system user name needs to be stored in the/root/liu_shell/local_user.txt file and then compared!

2. Determine whether the IP that is starting with 192.168.1 and 192.168.2 is the normal ip!

3. Judge Iptables status!
