Hello everyone
Can someone help me fix this problem?
I am using an example from Pyro(Python Remote Object) website
directly.
It is the last example from
http://pyro.sourceforge.net/manual/8-example.htm
I have two computers to run Server and Client.
############################################
server.py
import Pyro.naming
import Pyro.core
from Pyro.errors import PyroError,NamingError
###### testclass Pyro object
class testclass(Pyro.core.ObjBase):
def mul(s, arg1, arg2): return arg1*arg2
def add(s, arg1, arg2): return arg1+arg2
def sub(s, arg1, arg2): return arg1-arg2
def div(s, arg1, arg2): return arg1/arg2
###### main server program
def main():
Pyro.core.initServer()
daemon = Pyro.core.Daemon()
# locate the NS
locator = Pyro.naming.NameServerLocator()
print 'searching for Name Server...'
ns = locator.getNS(host='drizzle.des.hep.uiuc.edu', port=9090)
daemon.useNameServer(ns)
# connect a new object implementation (first unregister
previous one)
try:
# 'test' is the name by which our object will be known
to the outside world
ns.unregister('test')
except NamingError:
pass
# connect new object implementation
daemon.connect(testclass(),'test')
# enter the server loop.
print 'Server object "test" ready.'
daemon.requestLoop()
if __name__=="__main__":
main()
###################################
###################################
client.py
import Pyro.naming, Pyro.core
from Pyro.errors import NamingError
# locate the NS
locator = Pyro.naming.NameServerLocator()
print 'Searching Name Server...',
ns = locator.getNS(host='drizzle.des.hep.uiuc.edu',port=9090)
# resolve the Pyro object
print 'finding object'
try:
URI=ns.resolve('test')
print 'URI:',URI
except NamingError,x:
print 'Couldn\'t find object, name server says:',x
raise SystemExit
# create a proxy for the Pyro object, and return that
test = Pyro.core.getProxyForURI(URI)
print test.mul(111,9)
print test.add(100,222)
print test.sub(222,100)
print test.div(2.0,9.0)
print test.mul('*',10)
print test.add('String1','String2')
#######################################
It does not matter which computer Pyro NameServer is located.
When Server and Client are in a same computer, it works perfectly
fine.
But whenever Server and Client run in different computers, I get a
following error message.
########################################

Thanks a lot.
THis is just a guess - but it seems that somehow you don't bind your
pyro objects to the NIC's IP address, but to localhost (127.0.0.1) -
which of course won't work. That never happened to me though, try and
see the pyro docs on how to prevent/control to which IP a proxy is bound.
