Hi, I'm trying to implement a simple server. What I want the code to do is as follows: * Create a socket and listen on a port * Wait for an incoming connection * When a connection is received, fork a process to deal with it and go back to waiting for connections. I believe the following code should accomplish this (I have omitted the loop and the fork because I want to get it working for a single connection before I start with multiple connections!): server := Socket new. server listenOn: 1234. client := server accept. However when I run this I get Socket(Object)>>primitiveFailed. Examining the stack trace reveals the source to be this method: Socket>>primAcceptFrom:receiveBufferSize:sendBufSize:semaIndex: <primitive: 'primitiveSocketAccept' module: 'SocketPlugin'> ^self primitiveFailed When I take a look in /usr/local/lib/squeak/3.11.3-2135 there are lots of plugins, but no SocketPlugin. Swazoo seems to work fine without it and all of the tests in the NetworkTests package pass.
