When installing a TIBCO Streaming StreamBase node I am getting error:

(node install):     Installing node
(node install): Host name 'Users-MacBook-Pro-2.local' is not resolvable. getaddrinfo() failed with the error 
'nodename nor servname provided, or not known'. Add an entry for Users-MacBook-Pro-2.local to /etc/hosts or 
your site's hosts database.
(node install): returnCode = 255

Do I really need to add a hosts file entry for "Users-MacBook-Pro-2.local"?

This can occur when an active VPN connection interferes with IP address lookup for the hostanme reported by the operating system (Windows, Linux, or MacOS) or lookup for 'localhost' due to having multiple virtual network interfaces.

The error suggests one possible solution:

• On Linux and MacOS, the hosts file is in found in directory /etc.
• On Windows, the hosts file is found in directory C:\Windows\System32\drivers\etc.

Edit the OS's hosts file to include as the first active configuration line (change the hostnames as appropriate):

127.0.0.1    localhost simpleHostName qualifiedHostName.company.com

Another solution is to disable transient network interfaces such as VPN and WiFi.

Finally you may bind the node at install time to a specific network interface by IP address using command options:

epadmin install node adminport=N adminhost=N.N.N.N

This explicitly binds the discovery service port to a specific port on a specific IP address. This is normally used for Proxy Discovery when UDP Multicast is made unavailable by IT network policy. The default 'adminhost' IP address is blank, binding the listener to all available interfaces (which produces a list of potential hostnames leading to the lookup problem).. Bind the node to the IP address corresponding to the hostname reported by the OS (you may need to try each IP address until you find the one that avoids the error).
