are you running any kind of firewall/iptables/SELinux where the settings are perhaps not the same on the two machines?

I can do this: on the 192.168.111.11 box: -bash-3.1$ psql -h 192.168.111.13 Welcome to psql 8.2.6, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help with psql commands \g or terminate with semicolon to execute query \q to quit postgres=# However if I do this it fails: on the 192.168.111.13 box: -bash-3.1$ psql -h 192.168.111.11 postgres psql: could not connect to server: No route to host Is the server running on host "192.168.111.11" and accepting TCP/IP connections on port 5432? Both boxes have the same copy of the postgresql.conf file and the pg_hba.conf file. Here's the listen address setting (on the 192.168.111.11 box) from the postgresql.conf file: listen_addresses = '*' I also checked (after a restart) that the listen address and port was in fact as I thought on 192.168.111.11 : Welcome to psql 8.2.6, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help with psql commands \g or terminate with semicolon to execute query \q to quit postgres=# show listen_addresses; listen_addresses ------------------ * (1 row) postgres=# show port ; port ------ 5432 (1 row) postgres=# Here's the current pg_hba.conf file on 192.168.111.11 : # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all ident sameuser # IPv4 local connections: host all all 127.0.0.1/32 ident sameuser # IPv6 local connections: host all all ::1/128 ident sameuser #DRW. This should be tighted up once the db instances are figured out host all all 192.168.111.0/24 trust I'm stumped.. Anyone have any thoughts ?
