Pharo and network
Locked
 
|
Hello,
I read these documents: http://book.pharo-project.org/book/networking/Socket http://wiki.squeak.org/squeak/325 but I still don't get what I want with pharo. Here is the idea: I want a socket to listen a port while pharo is launched as a deamon. I tried to test the sockets with this idea: - creation of two sockets in two workspaces - server: | server st | st := String new. server := Socket newTCP. server listenOn: 12345 backlogSize: 4. server receiveDataInto: st - client: | s | s connectTo: ('127.0.0.1' asByteArray asSocketAddress) port: 12345. s sendData: 'Hello' - the connectTo:port: fails, and I don't understand why So I have no idea ... Adrien. |

Shouldn't this lead to a MNU? I don't know how to initialize a socket, but maybe you forget to instantiate the socket, or you have to talk to the class.

Could you try : | s | s := Socket new. s connectTo: (NetNameResolver addressForName: 'localhost') port: 12345. Best regards Olivier ;-) www.auverlot.fr Hello, |

yes... depending on your OS and version of Pharo, 127.0.0.1 does not
always work as the destination from your client to your server socket. Did Olivier's code snippet work? try using netcat or lsof (unix) to see and interact with the state of your sockets. There is also a SocketStream implementation (somewhere) that hides a lot of this. cheers, Mike On Fri, Jan 14, 2011 at 11:35 PM, Olivier Auverlot <[hidden email]> wrote: > Hi Adrien, > > Could you try : > > | s | > s := Socket new. > s connectTo: (NetNameResolver addressForName: 'localhost') port: 12345. > > Best regards > Olivier ;-) > www.auverlot.fr > > Hello, > > I read these documents: > http://book.pharo-project.org/book/networking/Socket > http://wiki.squeak.org/squeak/325 > > but I still don't get what I want with pharo. > > Here is the idea: I want a socket to listen a port while pharo is launched > as a deamon. > > I tried to test the sockets with this idea: > - creation of two sockets in two workspaces > - server: > > | server st | > st := String new. > server := Socket newTCP. > server listenOn: 12345 backlogSize: 4. > server receiveDataInto: st > > - client: > > | s | > s connectTo: ('127.0.0.1' asByteArray asSocketAddress) port: 12345. > s sendData: 'Hello' > > - the connectTo:port: fails, and I don't understand why > > So I have no idea ... > > Adrien. > > |
