Iam using a Ubuntu 17.10 VM in GCP. To prevent my server’s IP from being spoofed, I did the below changes in my /etc/host.conf file:
# The "order" line is only used by old versions of the C library. order hosts,bind multi on
# The "order" line is only used by old versions of the C library. order bind,hosts nospoof on
But this gave the below error:
/etc/host.conf: line 2: bad command `order bind,hosts' /etc/host.conf: line 3: bad command `nospoof on'
What is going wrong?
None of those obsolete options you placed in
/etc/host.conf have any effect anymore. And Google will prevent your IP from being spoofed; you don’t have to worry about it.
