LFD (Login Failure Daemon) is a security-related daemon that runs on Linux servers. It is designed to monitor and detect brute-force login attempts on the server and take appropriate action to block the offending IP addresses.
LFD is a sensitive daemon that reports every activity running on the server, including excessive processes and resource usage alerts, IP blocks, login failures, email queue size alerts, relay alerts, suspicious file or process alerts, load alerts, SYSLOG alerts, excessive process alerts, etc., and so much more.
To accomplish disabling mail alerts from LFD (Login Failure Daemon) on a Linux system, you can follow these steps:
- Open the LFD configuration file using a text editor like “nano” or “vim”.
vim /etc/csf/csf.conf
- Locate the following line in the configuration file:
LF_EMAIL_ALERT = "1"
- Change the value of this line to
LF_EMAIL_ALERT = "0"
- Save and exit the configuration file
- Restart the CSF service using the command:
csf -r
- Verify that the changes have taken effect by checking the status of the email alerts:
csf -g LF_EMAIL_ALERT
This should stop LFD from sending any more email alerts.
Thus, we completed the discussion on disabling mail alerts from LFD
