how to send a file between two nodes in Erlang?

Here's how to send a file between two nodes in Erlang:

1. Establish Node Connectivity:

• Start both Erlang nodes with unique names:
  Erlang

  erl -sname node1
  erl -sname node2
  

  Usa el código con precaución. Más información

  
  

Connect them using net_kernel:connect_node/1:

Erlang

(node1@host)1> net_kernel:connect_node('node2@host').
true

Usa el código con precaución. Más información

Verify connectivity with net_adm:ping/1:

Erlang

(node1@host)2> net_adm:ping('node2@host').
pong

2. Transfer the File Using RPC:

• On the sending node (node1):

  1. Read the file contents:
     Erlang

     {ok, Bin} = file:read_file("path/to/file").
     

     Usa el código con precaución. Más información

Call file:write_file/2 on the receiving node:

Erlang

rpc:call('node2@host', file, write_file, ["path/to/new_file", Bin]).

• On the receiving node (node2):

  • The file will be written to the specified path.

Key Considerations:

• File Handling:
  • Ensure proper permissions for file operations on both nodes.
  • Consider error handling for file I/O failures.
• Large Files:
  • For large files, explore alternative methods:
    • Stream the file in chunks using a custom protocol.
    • Use external file transfer mechanisms (e.g., FTP).
• Security:
  • Implement authentication and authorization for node connections in production environments.

Additional Options:

• External Libraries:
  • Consider libraries like gen_tcp or gen_udp for custom file transfer protocols.
• File System Synchronization:
  • For shared file systems, use Erlang's built-in file system monitoring capabilities.
