Protect Your Mining & Node Centos 7 Servers With Fail2Ban
Written by CC Freak on August 8, 2017
So you just received a bunch of credits from a VPS provider and you want to start mining or simply host a node. A simple way to protect your new Centos 7 mining and/or node server is to install Fail2ban to prevent SSH brute force attacks to guess your root password. This article isn’t about top notch security and I realize that you can disable root login and/or disable password login. This is for those that simply want decent security while still maintaining root login with password.
Lets get started:
yum -y install epel-release yum -y install fail2ban systemctl enable fail2ban nano /etc/fail2ban/jail.local
and copy the following into jail.local
[DEFAULT] # Ban hosts for one hour: bantime = 3600 # Override /etc/fail2ban/jail.d/00-firewalld.conf: banaction = iptables-multiport [sshd] enabled = true
Save and restart
systemctl restart fail2ban
Check status
fail2ban-client status
Your mining and/or node server now has a bit more security for whatever coin you are supporting! If you found this helpful, consider a donation!
