Mine has a "user" column, which yours skipped. It would be:

local all all 10.17.11.0 255.255.255.0 trust

You must also make sure you restart the server. Try connecting on localhost
or 127.0.0.1.

PS, are you actually on a Class C network? If you are, then your subnet mask
might be 255.0.0.0, or something else entirely.
