When I tried to post a new topic in Socket and Protocols with the following title and message: TCP/IP stack implemented with Java I just wonder if anyone in this world has ever inplemented the TCP/IP stack with Java. Maybe that's too slow compared with C. And I really find the TCP/IP related Java classes have much fewer arguments than the corresponding C methods, thus much simpler and lacking full functions. Is it possible to implement TCP/IP stack in a way that you can dynamically configure proper parameters, such as TIME_WAIT, sendbuffer, recvbuffer, according to the network conditions (eg. too congested at the moment). Anyone has ever heard about that?? I'm thinking about that seriously now. I got the following problem: Can't open /home/vhost1/www.javaranch.com/vroot/ubb/test.file: Permission denied Here is the backtrace: Backtrace: ubb_lib_filehandle.cgi:294 -> sub UBB::FileHandle::tracer Backtrace: ubb_lib_filehandle.cgi:382 -> sub UBB::FileHandle::_open Backtrace: ubb_lib_filehandle.cgi:58 -> sub UBB::FileHandle::_open_file Backtrace: ubb_lib_filehandler.cgi:116 -> sub UBB::FileHandle::new Backtrace: ubb_lib_files.cgi:519 -> sub UBB::FileHandler: pen Backtrace: ubb_new_topic.cgi:414 -> sub main::WriteFileAsString Backtrace: ultimatebb.cgi:603 -> sub main::submit_new_topic
