Installing Fail2Ban on CentOS 7

Fail2Ban is an important utility on the modern Internet for stopping “port probe” and other repeat intrusion/login attempts on your Internet services. The following describes how to install and initially configure it to monitor & block repeated login failures on the SSH service.

It isn’t in the standard CentOS 7 Repositories, but is easily installed and configured with the following commands and settings done as the root user:

a) The Fail2Ban package is in the EPEL-Release repository which is activated with the command:

yum install epel-release

b) After the above which makes the EPEL Release Repository available for use, Fail2Ban is installed with:

yum install fail2ban
(type ‘y’ to confirm the EPEL Key etc)

c) Fail2Ban is activated on the system with the command:

systemctl enable fail2ban

A quick SSH based default config for fail2ban is achieved by loading the following lines to the newly created file /etc/fail2ban/jail.local

[DEFAULT]
# Ban hosts for one hour:
bantime = 3600

# Override /etc/fail2ban/jail.d/00-firewalld.conf:
banaction = iptables-multiport

[sshd]
enabled = true

The above configured Fail2Ban to block repeat offenders for 1 hour, to use the IPTables Firewalling capabilities on the SSH port of 22.

After loading the above to the jail.local file, restart the fail2ban service with:

systemctl restart fail2ban

You can check on fail2ban’s operations with the command:

fail2ban-client status

FYI,
Richard.

Data Centre, Network & POP Maintenance Notice – Wed & Thu evenings, December 7th/8th 2016

During the evenings of Wednesday and Thursday, December 7th and 8th, from 10pm each night (through to 6 am on the next morning) we will be performing upgrades to selected hosting server platforms of Network Presence in Sydney, Australia.

Customers with services (VPS) on the hosting platforms to be upgraded may be emailed advisory notices shortly, and this is a general notice related to other ancillary upgrades and Infrastructure Maintenance being performed during this scheduled window of time.

This Maintenance Window starts from 10pm Sydney time on the evenings of Wednesday and Thursday, December 7th & 8th 2016 through to 6am on the following morning each day, and I’ll be personally contactable by phone & online during and after these works in-case there’s any issues that arise. During this Maintenance Window, selected network or server equipment will be worked on, upgraded and restarted. Works will be completed as quickly as possible (where possible, timing information will be in emails to affected customers) and restarts are short service interruptions only, while upgrades may incur longer service interruptions.

This will incur outages to selected hosting services of Network Presence in Australia during this off-peak scheduled works period.
In addition, there may be some impact (short 5-10 minute periods) to the general Internet Connectivity of portions of Network Presence in Sydney during these works, though redundant routing will be utilised during these works.

Progress updates during the works will be posted to our Operations Twitter Feed at https://twitter.com/netpresops

FYI and regards,
Richard.
