Ok... taking a second look at the strace I sent there... :) The problem is actually clear, nsock has no problems with network input, but with stdin input! dup(0) = 4, then recv(4, ...) = -1 errno ENOTSOCK means that recv() refuses to read from stdin as not being a real socket. ncat.h: struct conn_state { nsock_iod tcp_nsi; nsock_iod stdin_nsi; [...] So we have a minor design issue there, if we do not want to copy any nsock code for nmap. My proposal is that we could have an additional "real_socket" field in "struct mspool" that takes care of making a difference between non-network (stdin) and network socket. read() only for stdin should even work on Win32. ;) And only ncat would need to set that flag when initializing their conn_state.stdin_nsi. $.02 _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
