psql: error: could not connect to server: could not connect to server: Connection refused Is the server running on host "10.14.202.76" and accepting TCP/IP connections on port 9999?
If you run `netstat` on the machine with the database, does this port show up as a listening port? Also, #postgresql normally uses port 5432 ... did you change the config to make it use 9999 instead?
Most DBMSs listen only for local connections unless manually configured differently. (No one wants to find out accidentally that their database is accessible to places they didn't intend.) So check your database config.
What happens when you try `telnet 10.14.202.76 9999` (or `telnet 10.14.202.76 5432` as appropriate)?
