查询词典 bytes

To read this off from left to right:"Load the u32 module, and perform the following u32 tests on this packet; grab the 4 bytes starting with byte 2 (bytes 2 and 3 are the Total Length field, and bytes 4 and 5 are the IPID), apply a mask of 0x0000FFFF (which sets the first two bytes to all zeroes, leaving the last two bytes untouched), and see if that value - the IPID - falls between 2 and 256 inclusive; if so, return true, otherwise false."

从左到右读这条命令是：&加裁u32模块，并且在数据包上执行下面的u32测试；从第2个字节开始抓取4个字节，应用0x0000FFFF掩码，然后查看这个值，如果在2到256之间，那么返回真，否则返回假。&

到这里，就已经将原先的windows的E盘（2501到5000柱面），那个/dev/sda6分成了三个区。现在如果保存分区操作后，再使用格式化工具创建文件系统后，原先的 2501到5000柱面上的数据将丢失。当然，我们不必担心，因为事先已经将文件复制到了其它的地方了。注意：现在有一个问题，看上面/dev/sda11 的尾柱面是 5000 ，而/dev/sda6的首柱面是5001 。一直到/dev/sda8 的首柱面都位于/dev/sda11的尾柱面之后。也就是说它们的物理位置在后面，但分区编号在前面。为改变这一状况，有一个简易的方法。就是先删紧靠 5000柱面之后的一个分区，然后立即按默认首柱面和尾柱面进行分配，在重建分区表的时候注意把分区的系统标识也改也原先的（因为 Linux的fdisk中默认的新建的分区系统标识为id为83。

We see the signature value of 0x504d in bytes 0 to 1 and the number of partitions in bytes 4 to 7, which is 10 (0x0000000a). Bytes 8 to 11 show us that the first sector of the disk is the starting sector for this partition and that its size is 63 sectors (0x3f). The name of the partition is "Apple," and the type of partition is "Apple_partition_map." Bytes 88 to 91 show that no flags for this partition are set.

我们可以看到0-1字节处签名值为0x504d，4-7字节处的分区总数为10，8-11字节处表示硬盘的第一扇区是该分区的起始扇区，它的大小为63扇区（0x3f），分区名称为"Apple"，分区类型为"Apple partition map"，88-91字节处显示该分区无设置标志。

The common method of disassembly, referred to as the linear sweep method, assumes that all bytes starting from the entry point of a binary are instructions, and disassembles the entire code segment, following successive bytes.

反汇编的通常方法，即所谓线性扫描方法，假定从二进制代码入口点开始的所有字节是指令，并且顺序反汇编整个代码段字节。
