Description: tcpick is a textmode sniffer that can track TCP streams and saves the data captured in files or displays them in the terminal. It is useful for picking files in a passive way. It can store all connections in different files, or it can display all the stream on the terminal with colors.

Description: 计算校验和
校验和算法描述：为保证网络上传输的数据的可靠性，在许多协议中都设置了校验和项，例如：IPv4、ICMPv4、IGMPV4、ICMPv6、UDP和TCP 等等。计算这些校验和的算法称为网际校验和算法，简单来说就是：把被校验的数据１６位进行累加，然后取反码，若数据字节长度为奇数，则数据尾部补一个字节的０以凑成偶数。
由于从输入文件读入的数据不能直接满足计算校验和的条件，所以首先对从文件读入缓冲区的数据进行预处理，即读入缓冲区时忽略空格。由于累加是按16位进行的，所以每次从缓冲区中读出4个字符，并将字符转换成对应的16进制数字，如此依次累加，直至数据全部读完。
还有一种情况，即如果数据长度为奇数个字节，则需要判断，并补0累加。程序中利用的是缓冲区长度计数器i和当前读取到计数器j判断数据长度是否为奇数。即如果数据长度为偶数，则读完数据时当前读取到计数器j的值应与缓冲区长度i相等，而如果数据长度为奇数，则读完数据时，当前读取到计数器j>缓冲区长度i，此时需将缓冲区中剩余的两个字符读出，并补0，转换成相应16进制数以后参与累加。
当累加结束后，将累加和的16位以上数据位移下再进行一次累加，并对最后累加和取反即得所求校验和。

Description: 我们用得最多的协议是UDP和TCP，UDP是不可靠传输服务，TCP是可靠传输服务。UDP就像点对点的数据传输一样，发送者把数据打包，包上有收信者的地址和其他必要信息，至于收信者能不能收到，UDP协议并不保证。而TCP协议就像(实际他们是一个层次的网络协议)是建立在UDP的基础上，加入了校验和重传等复杂的机制来保证数据可靠的传达到收信者。关于网络协议的具体内容，可以参考专门介绍网络协议的书籍，这里直接探讨编程实现网络程序的问题。-We use the most agreement is UDP and TCP, UDP is not reliable transport services, TCP is a reliable transport service. UDP as point-to-point data transmission, the sender of data packing, has prepared to receive packets on the address and other necessary information for the receiver can not receive, UDP does not guarantee agreement. The TCP protocol is like (actually they are a level of network protocol) is built on the basis of UDP, joined the checksum ARQ complex mechanism to ensure that reliable data were communicated to the receiver. With regard to the specific content of network protocols, you can refer to specialized network protocols introduce the books, here to explore the direct network programming procedures.

Description: IP/UDP/TCP/ICMP的校验和
在发送数据时，为了计算数IP据报的校验和。应该按如下步骤：
(1) 把IP数据报的校验和字段置为0。
(2) 把首部看成以16位为单位的数字组成，依次进行二进制反码求和
(3) 把得到的结果存入校验和字段中。
在接收数据时，计算数据报的校验和相对简单，按如下步骤：
（1）把首部看成以16位为单位的数字组成，依次进行二进制反码求和，包括校验和字段。
（2）检查计算出的校验和的结果是否等于零。
（3）如果等于零，说明被整除，校验是和正确。否则，校验和就是错误的，协议栈要抛弃这个数据包。-IP/UDP/TCP/ICMP checksum and

Description: 自己写的C# DOSS攻击实例 通过tcp 协议是3次握手的方式连接的，第一次客户机向服务器发送一个标志为syn的数据包，这个数据包的tcp部分有个16位随即序列号，而且ip部分和tcp部 分各有一个校验码，发送出去只有校验码正确才会视为合法的数据包，然后如果那个机器那个端口有服务器，比如http服务，就会把序列号+1，然后再生成一 个16位随机序列号，标志syn+ack的数据包返回，服务器就会占着一个信道等待第三次握手了，如果超过预定时间等不到就超时去掉了，这时如果开始那个 syn的源ip地址和源端口是伪造的并大量发送，服务器就会大量的向假ip端口返回syn+ack并等待，这样就大量占着信道了，如果超过了连接限制，别 的机器就连不上了，就拒绝服务了。原理大体就是这个样子了。-Write your own C# DOSS attack instance handshake connection through tcp protocol, the first time the client sends to the server a flag for the syn packet, this packet tcp part of a 16 then the serial number, and ip part and tcp part one on each check code sent only correct checksum will be regarded as the legitimate packets, and then if that machine that port server, such as http service serial number will+1, then regenerated into a 16-bit random serial number, logo syn+ack packet returns, the server will occupy a channel exceeds a predetermined time less than a timeout to remove the wait for the third handshake, then if you start the syn source ip address and the source port and send a large number of forged server will be a lot of to fake ip port to return syn+ack and waiting for, so that a large number of occupied channel, if the connection limit is exceeded, the other machines on the crawl denial of service. Principle roughly like this.
