syn. 基本例句 =synonym同物异名 A client initiates a connection to a host and a specific port by sending a SYN/span> synchronize packet. 客户机通过发送 SYN同步数据包发起到一个主机和特定端口的连接。 ibm In response, the scanned host returns a packet with the SYN and ACK flags set if the port is open. 如果该端口是打开的,则被扫描主机返回设置了 SYN和 ACK标志的包进行响应。 ibm The problem that can occur with TCP is when a rogue client forges an IP packet with a bogus source address, then floods a server with TCP SYN packets. 当恶意客户机使用虚假的源地址来伪造一个 IP报文时, TCP就会出现问题了,这会大量 TCP SYN报文攻击服务器。 ibm The server allocates resources for the connections upon receipt of the SYN, then under a flood of SYN packets, eventually runs out and is unable to service new requests. 服务器在接收 SYN 报文之前,要为连接分配资源,但是在大量产生 SYN报文的情况下,最终会耗尽自己的资源,从而无法处理新的请求。 ibm The server answers with a packet where both the SYN and ACK flags are set. 服务器以设置了 SYN和 ACK标志的包应答。 ibm The syn-gas, or the syn- fuel process. 合成气或合成燃料技术。163 After the collapse of the Empire as known and cherished by Syn, he again found solace in another religion, this time the Church of the Dark Side. 在西恩获悉他所珍视的帝国崩溃之后,他又一次从别的宗教中获得了慰藉,而这一次的宗教是黑暗教会。 starwarschina And obviously this process, the syn- fuel process, is coming back in vogue with the energy crisis around now. 很明显这个过程,合成燃料的过程,随着能源危机的到来,变得又时髦起来了。163 As a result, the stack may be overflowed by SYN flooding attack, which will cause the connection break off. 这种漏洞使系统可能受到 SYN洪水攻击而导致堆栈溢出,连接中断。 cnki As discussed above, when Host A wants to establish a TCP connection to destination Host D, it sends a TCP segment with the SYN flag set first. 如上所述,当主机 A想建立到目的地主机 D的 TCP连接时,它首先发送设置了 SYN标志的 TCP段。 ibm Enough SYN requests to the system, and an attacker can use all the connections on a system so that nothing else can get through. 只要针对系统的 SYN请求足够多,攻击者就能够使用系统上的所有连接,从而阻止任何东西通过。 ibm However, in answer to the SYN/ ACK packet the attacker will send a packet with the RST and ACK flags set. 但是,攻击者会发送设置了 RST和 ACK标志的包回应 SYN/ ACK包。 ibm TCP SYN Scanning is also known as half open scanning. TCP SYN扫描也称为半开扫描。 ibm The first setting enables TCP SYN cookies. 第一个设置启用 TCP SYN cookie。 ibm This means a TCP packet with the SYN flag set is sent to the server. 这意味着向服务器发送一个设置了 SYN标志的 TCP包。 ibm To accomplish this, the attacker sends a TCP packet with the SYN flag set to the target host, just like when opening a regular TCP connection. 要实现这一点,攻击者向目标主机发送设置了 SYN标志的 TCP包,就象打开常规 TCP连接时一样。 ibm When a new TCP connection comes in from a client by means of a packet with the SYN bit set, the server creates an entry for the half-open connection and responds with a SYN- ACK packet. 当从客户机发来新的 TCP连接时,数据包设置了 SYN位,服务器就为这个半开的连接创建一个条目,并用一个 SYN- ACK数据包进行响应。 ibm When receiving this segment, Host D acknowledges it by returning a packet with the SYN and ACK flags set. 当接收这个段时,主机 D通过返回设置了 SYN和 ACK标志的包确认它。 ibm You can specify which incoming TCP packets to scan and discard those that don't match the flags ACK, FIN, PSH, RST, SYN, or URG. 可以指定应该扫描哪些到达的 TCP数据包,丢弃不与 ACK、 FIN、 PSH、 RST、 SYN或 URG标志匹配的数据包。 ibm You can see that the attacker will only have to send a few SYN packets every ten seconds or so to disable a specific port. 您会发现,攻击者只要每十秒钟左右发送几个 SYN包就可以禁用特定端口。 ibm Syn's future pointed to him becoming a“Pera” upon reaching adulthood, but after the Empire intervened and Syn was told to discard his beliefs, this dream was forgotten. 本来西恩将在成年后成为一个神父,但由于帝国当局的干预,西恩被告知必须放弃自己的信仰,于是这一梦想被渐渐遗忘。 starwarschina |
