Test TCP and TLS connectivity separately in the Geo setup instructions
This came up in the Geo demo of 2017-12-05
Test connection between the servers with netcat on same port and protocol (443, http? No: 5432 or the test is meaningless) without TLS to detect firewall problems. => Nick: I’ll add this
Currently, we provide a psql
command that checks both firewall and TCP at the same time. We should include a netcat
(or other) command that:
- Tests that TCP to port 5432 on the primary works from the secondary
- Times out quickly if the firewall is dropping, rather than rejecting, packets.
