To check the packet loss issue caused by rate-limiting ICMP (ping) requests in CSF (ConfigServer Security & Firewall),
you'll need to adjust the configuration. Here's how you can do it:
1. Access your server via SSH: Use your preferred SSH client to connect to your server.
2. Edit the CSF configuration file: Navigate to the directory where CSF is installed. Typically, the configuration file is located at /etc/csf/csf.conf. You can edit it using a text editor like nano or vi.
For example:
# nano /etc/csf/csf.conf
3. Find the ICMP rate-limiting configuration: Look for the ICMP_IN_RATE setting in the CSF configuration file. It may be set to 1/s as indicated by your hosting company.
ICMP_IN_RATE = '1/s'
4. Adjust the ICMP rate-limiting setting: Change the value of ICMP_IN_RATE from "1/s" to "0". This will disable rate-limiting for ICMP requests.
ICMP_IN_RATE = "0"
5. Save the changes: After making the adjustment, save the csf.conf file with:
"Ctrl+X" then press "Y" and "Enter" to save the file and exit the text editor.
6. Reload CSF: Run the following command to apply the changes to the CSF configuration:
# csf -r
This command will reload CSF with the new configuration settings.
This will disable rate-limiting for ICMP requests.
