Use sysread() and syswrite() instead of read() and send() to avoid blocking on the read. But you need to implement some kind of message protocol. There's no way to guarantee that one sysread() will read the entire message from the client. Also, I *strongly* suggest you use the IO::Socket module, as it encapsulates a lot of gory details for you. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
