Simply to avoid many problems in the first place I do not want my postgres server program to accept/listen to anything from any network (i.e. TCP/IP 4/6) connections.
My setup is a Postgres 9.1 on an Ubuntu 12.04 box and I thought tweeking
/etc/postgresql/9.1/main/pg_hba.conf to not include those lines which commented out (see below) would cause postgres to "please not listen on network TCP/IP devices"
local all postgres trust # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only #local all all md5 # IPv4 local connections: #host all all 127.0.0.1/32 md5 # IPv6 local connections: #host all all ::1/128 md5
Also I know that there is the
-i command line to start the postgres server with if we YES want to listen on TCP/IP . I actually seek for the opposite thing a
-??? meaning NO please do NOT listen on TCP/IP.
I used a
netstat -utap | grep post and it shows that postgres besides my settings in
/etc/postgresql/9.1/main/pg_hba.conf is still listening on TCP/IP.
What did I do wrong here? How can I shut off this TCP/IP listening attitude of my Postgres server? Having only unix socket listening I am happy to the max ;)
Addition: I also perceive that postgres establishes a UDP connection to this
127.0.0.1:38860, what would this be about?
