OSX Sierra hosts file is ignored
Look at System Preferences -> Network
If the currently active "Location" has one or more DNS servers listed then the system will create the file "/etc/resolv.conf" which will list those nameservers as the place to go for resolution, bypassing /etc/hosts entirely
resolv.conf is created dynamically by "Network" prefs, and overwritten based on the "DNS Server" field of the currently active "Location" or removed if that field is blank
The file might be corrupted/damaged, it has to be an ASCII file. You should recreate it:
- move the old file with
mv -f /etc/hosts /etc/oldhosts - create a new file with
nano - populate it with the values of the old file
- save it as
/etc/hosts
That should do it.
Also, make sure your list of hostnames doesn't exceed 20 names. I frequent a site which likes to put advertisements in your face, so I assign the FQDN from the popup as an alias of localhost. Recently I found my hosts file wasn't working. Seems the limit is 20 hosts... Example:
