Try fseek, because you need to return to the beginning of the file.

        new File:zeport = fopen("/Log/zeport.log", io_read);

        new max_lines = lines;
        lines = 0;
        fseek(zeport, 0);
        while(lines < max_lines - 10)
        {
            fread(zeport, str); //moving the pointer a line down until its on the 10th line from the back
