I'm using Ubuntu Server 9.10 AMD Phenom 2 cpu g++ (Ubuntu 4.4.1-4ubuntu9) 4.4.1

trying to run the application pftp-shit v 1.11.

The following code in tcp.cc is executed successfully: int outfile_fd = open(name, O_CREAT | O_TRUNC | O_RDWR | O_BINARY)) which returns a file descriptor int (in my case 6) - name is a char array containing a valid path to my file which successfully i created. and successfully running: fchmod(outfile_fd, S_IRUSR | S_IWUSR); and access(name, W_OK)

The issue occurs during running the function (from sys/uio.h) write(outfile_fd, this->control_buffer, read_length) which returns -1. -1 is of returned if nothing was written and otherwise a non-negative integer is returned which is equal to the number of bytes written.

Anyone having a clue how I can get the write function to work?
