TCP connection succeeded but Erlang distribution failed-DPDK中文网

If you are experiencing a situation where the TCP connection is successful but Erlang distribution is failing, it could be due to several reasons. Here are some potential troubleshooting steps:

Check the firewall settings: Ensure that the necessary ports for Erlang distribution (usually port 4369) are open and not blocked by any firewalls or network configurations.
Verify hostname resolution: Make sure that the hostname or IP address used for Erlang distribution is correctly resolved and accessible from both sides of the connection. You can test this using ping or nslookup commands.
Verify cookie mismatch: Erlang nodes use a shared secret called “cookie” to authenticate and establish connections. Ensure that both nodes have the same cookie value configured in their respective Erlang runtime environments (usually specified in the .erlang.cookie file).
Check network connectivity: Validate that there is proper network connectivity between the two nodes, including routing, DNS resolution, and any VPN configurations if applicable.
Upgrade/patch versions: If you’re using different versions of Erlang/OTP on each node, there might be compatibility issues. Try upgrading or patching to compatible versions.
Review error messages/logs: Examine any error messages or log files generated during the failed Erlang distribution attempt to identify specific issues or error codes that can provide further insights into the problem.

If these steps do not resolve the issue, consider consulting relevant documentation or seeking assistance from experienced Erlang developers or support channels for more specific guidance based on your particular setup and configuration details.
