i try to use zerorpc python client like this:

import zerorpc

c = zerorpc.Client()
c.connect("tcp://127.0.0.1:4242")
print c.hello("RPC")

and i get this error at start

Traceback (most recent call last):
  File "/Programming/python/snmp01/snmp01.py", line 34, in <module>
    print c.hello("RPC")
  File "/Library/Python/2.7/site-packages/zerorpc-0.4.3-py2.7.egg/zerorpc/core.py", line 256, in <lambda>
    return lambda *args, **kargs: self(method, *args, **kargs)
  File "/Library/Python/2.7/site-packages/zerorpc-0.4.3-py2.7.egg/zerorpc/core.py", line 241, in __call__
    return self._process_response(request_event, bufchan, timeout)
  File "/Library/Python/2.7/site-packages/zerorpc-0.4.3-py2.7.egg/zerorpc/core.py", line 225, in _process_response
    raise
zerorpc.exceptions.RemoteError: Error: Hello, RPC
    at Server._recv.result (//Programming/node/snmp01/node_modules/zerorpc/lib/server.js:146:55)

any idea?

The docs are currently wrong. If there is no error on the node side, you need to pass null as the first argument to reply. The first argument is for errors (as it says further down in the docs.)

My CoffeeScript code that works looks like this:

zrpc = require 'zerorpc'
server = new zrpc.Server
  hello: (name, reply) ->
    reply null, "Hello, #{name}!"
server.bind 'tcp://0.0.0.0:4242'
