java - Socket clientSocket = serverSocket.accept(); cannot be resolved - after years of creating small- medium-scale flash games (and little java command-line apps), i'm ready introduce myself world of sockets :). i'm pretty sure i've grasped decent understanding can't work out why wont work... seems work everywhere else i've seen it. try { serversocket serversocket = new serversocket(6644); } grab (ioexception e) { e.printstacktrace(); } while(true){ socket clientsocket = serversocket.accept(); } eclipse keeps telling me 'cannot resolved' when hover mouse on serversocket on clientsocket = serversocket.accept(); line. variable exists , there isn't typo what's matter? i've imported java.io.* , java.net.* i'm pretty sure have need. your serversocket variable visible within try block. move declaration outside, maybe this: serversocket serversocket = null; seek { serversocket = new serversocket(664

linux - Is anyone using netlink for IPC? - i planning utilize netlink communication between 2 userland processes. part of reason beingness picky netlink - of processing 1 of process go in kernel space , netlink based communication can used (hopefully). the approach taking - define new generic netlink family (i have write kernel module back upwards family - appears @ moment). fine, looking @ illustration code, kernel routing messages between different processes , not doing work - actual population of messages handled processes. my question - using netlink in similar manner in of projects? - above approach makes sense? i read proposal netlink based dbus. haven't found implementation of that. comes closest requirements. thanks. what looking netlink_usersock if want communicate between userspace processes. netlink documentation awfully scarce unfortunately. might help bit: who can give me latest netlink programming samples? just create sure nl_pid non-zer
