Symptoms

/var/log/messages file on Gaia OS Security Gateway repeatedly shows:
modprobe: FATAL: Could not open '/lib/modules/2.6.18-92cpx86_64/kernel/net/ipv6/ipv6.ko'
There are no additional error messages related to IPv6 in the /var/log/messages file (e.g., "Unable to open '/dev/fw6v2'").

Cause

The error message appears when IPv6 is disabled on Security Gateway running Gaia OS.

By default, the IPv6 module is located in the /lib/modules/2.6.18-92cpx86_64/kernel/net/ipv6/ipv6.ko

When IPv6 is disabled, the IPv6 module should not be loaded. Therefore, when IPv6 is disabled, the path to IPv6 module is changed to /lib/modules/2.6.18-92cpx86_64/kernel/net/.ipv6/ipv6.ko (note the dot in the folder's name - ".ipv6")

This message is printed because the module is not found.
