hi @rymurr yes, figured its just a typo in README.md -Denable **d** I see you published ver 4.1.8 in docker hub, any specific changes related to flight protocol in this version? ---

Hey @smora, There is nothing in 4.1.8 that should affect flight. Please let us know if I am wrong! Best, Ryan ---

Hi @rymurr, when you planning to release dremio-oss image with arrow flight protocol ? ---

Hey @VahagnBleyan, We are currently working to incorporate the plugin into the product. In the meantime check out [https://github.com/dremio-hub/dremio-flight-connector/blob/master/Dockerfile](https://github.com/dremio-hub/dremio-flight-connector/blob/master/Dockerfile) this is an example of how to easily add the flight connector to the `dremio-oss` image. ---

Hi @rymurr I m facing a similar issue. I tried connecting to dremio using python , but getting an error as: File “pyarrow/\_flight.pyx”, line 944, in pyarrow.\_flight.FlightClient.authenticate File “pyarrow/\_flight.pyx”, line 68, in pyarrow.\_flight.check\_flight\_status pyarrow.\_flight.FlightUnavailableError: gRPC returned unavailable error, with message: failed to connect to all addresses ---

Hey @Rutuja, It is hard to say from this only: 1. what version of Dremio are you using 2. what version of the flight connector are you using 3. can you verify in the server logs that the flight connector has started 4. can you telnet to port 47470 from localhost or from an external machine Best, Ryan ---

Hi @rymurr looks like host binding fix is broken in latest ver of dremio(\>=4.1) after specifying -Ddremio.flight.host=0.0.0.0, service is still attached to local ip ``` dremio@dremio-master-0:/opt/dremio$ ss -tuln Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port tcp LISTEN 0 128 ::ffff:10.42.4.109:47470 :::* tcp LISTEN 0 128 :::45678 :::* tcp LISTEN 0 50 :::9047 :::* tcp LISTEN 0 1 ::ffff:127.0.0.1:42744 :::* tcp LISTEN 0 128 :::31010 :::* dremio@dremio-master-0:/opt/dremio$ ``` ---

hey @smora this flag was removed in the flight connector and flight should bind to all interfaces now, see [https://github.com/dremio-hub/dremio-flight-connector](https://github.com/dremio-hub/dremio-flight-connector) for the updated jvm params ---

hi @rymurr same result with all these options > -Ddremio.flight.host=0.0.0.0 > -Ddremio.flight.host=localhost > did not specify -Ddremio.flight.host in all the cases service is binding to local ip address and remote clients not able to establish a connection could it be related to ssl changes? i see `InetAddress.getlocalHost().getHostName() is passed to sslHelper` by default > :ffff:10.42.4.109:47470 instead of ::::47470 ---

Hi, we have latest version of Dremio on Docker, and we also cannot manage to access remote Arrow flight. From host to container works: telnet 172.17.0.2 32010 Trying 172.17.0.2… Connected to 172.17.0.2. But remote, not. Iptables rules are forwarding, but there is no listening port 32010 on all interfaces. ---

@mtance Is the IP your coordinator host? When you say “cannot manage to access remote Arrow flight.”, do you see an error? Can you please share more info ---

This is info from settings: ![slika](https://us1.discourse-cdn.com/flex020/uploads/dremio/original/2X/a/aa4c2b7794467319547aec6e77b102545af96480.png) So, If I want to connect to Arrow Flight (using telnet) on coordinator host via 172.17.0.2:32010 it is working, but if I want to connect on coordinator host via external WAN IP, it is not working. Iptables firewall rule in made, so there is issue with binding service port 32010 on Dremio I think. ---

Hi, when I tried to connect from host to container - locally I got telnet Connection successfull, when I try to connect outside - via internet i got Connection timed out (before I make firewall iptables rule I got Connection refused). Thanks ---

@mtance Any chance you can test this in a non-docker deployment like a GCE VM? just to narrow down that it is something to do with Docker? ---

@mtance Let us try something, change the ODBC/JDBC port to 32010 and use 31010 for flight and see if flight works and ODBC breaks, just to narrow down the issue In dremio.conf add services.coordinator.client-endpoint.port: 32010 services.coordinator.flight.port: 31010 Restart cluster [Previous page](https://community.dremio.com/t/arrow-flight-protocol/3855.md?page=2)
