Hi. I'm using CentOS 5.3 and PostgreSQL version 8.1.11. I opened the posgres SQL to accept incoming connections: <snip start from postgresql.conf> listen_addresses = '*' # comma-separated list of addresses; # defaults to 'localhost', '*' = all port = 5432 max_connections = 100 <snip end> It seems that the posgres SQL sometimes listen on other ports than 5432: # lsof -i -n -P | grep postg postmaste 18415 postgres 3u IPv4 99670 TCP *:17583 (LISTEN) postmaste 18415 postgres 4u IPv6 102029 TCP *:5432 (LISTEN) postmaste 18415 postgres 5u IPv4 102030 TCP *:5432 (LISTEN) postmaste 18415 postgres 8u IPv4 102038 UDP 127.0.0.1:53420->127.0.0.1:53420 postmaste 18421 postgres 3u IPv4 99670 TCP *:17583 (LISTEN) postmaste 18423 postgres 3u IPv4 99670 TCP *:17583 (LISTEN) postmaste 18423 postgres 8u IPv4 102038 UDP 127.0.0.1:53420->127.0.0.1:53420 postmaste 18424 postgres 3u IPv4 99670 TCP *:17583 (LISTEN) postmaste 18424 postgres 8u IPv4 102038 UDP 127.0.0.1:53420->127.0.0.1:53420 postmaste 18425 postgres 3u IPv4 99670 TCP *:17583 (LISTEN) postmaste 22242 postgres 3u IPv4 99670 TCP *:17583 (LISTEN) postmaste 22242 postgres 8u IPv4 102038 UDP 127.0.0.1:53420->127.0.0.1:53420 postmaste 22242 postgres 9u IPv4 117409 TCP 127.0.0.1:5432->127.0.0.1:55254 (ESTABLISHED) postmaste 22270 postgres 3u IPv4 99670 TCP *:17583 (LISTEN) postmaste 22270 postgres 8u IPv4 102038 UDP 127.0.0.1:53420->127.0.0.1:53420 postmaste 22270 postgres 9u IPv4 117489 TCP 127.0.0.1:5432->127.0.0.1:55256 (ESTABLISHED) The extra port which is being used (17583) is a port that i need to other services.
