Fix Recommendation

To set the runtime status of the "net.ipv4.conf.all.log_martians" kernel parameter, run the following command:

# sysctl -w net.ipv4.conf.all.log_martians=1

Set the system to the required kernel parameter by adding the following line to "/etc/sysctl.conf" or a config file in the /etc/sysctl.d/ directory (or modify the line to have the required value):

net.ipv4.conf.all.log_martians = 1

Issue the following command to make the changes take effect:

# sysctl --system

Check Contents

The status of the "net.ipv4.conf.all.log_martians" kernel parameter can be queried by running the following command:

$ sysctl net.ipv4.conf.all.log_martians
net.ipv4.conf.all.log_martians = 1

$ grep net.ipv4.conf.all.log_martians /etc/sysctl.conf /etc/sysctl.d/*
net.ipv4.conf.all.log_martians = 1


If "net.ipv4.conf.all.log_martians" is not configured in the /etc/sysctl.conf file or in the /etc/sysctl.d/ directory, is commented out or does not have a value of "1", this is a finding.
