A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo replies.
When a ping of death is initiated, it is my understanding that the command used, i.e. "ping -l 65536" will cause an oversized ping packet to be sent to the host by inserting 65536 bytes into the ICMP data field. As the ping is sending, then ICMP makes an ICMP_ECHO_REQUEST and this ICMP_ECHO_REQUEST is 65536 bytes. This together with the rest of ...
On devices like modems, bytes may be more than 8 bits long because they may be individually padded out with additional start and stop bits; the figures below will reflect this. Where channels use line codes (such as Ethernet , Serial ATA , and PCI Express ), quoted rates are for the decoded signal.
The round-trip time or ping time is the time from the start of the transmission from the sending node until a response (for example an ACK packet or ping ICMP response) is received at the same node. It is affected by packet delivery time as well as the data processing delay , which depends on the load on the responding node.
For file sizes, it is usual for someone to say that they have a '64 k' file (meaning 64 kilobytes), or a '100 meg' file (meaning 100 megabytes). When talking about circuit bit rates , people will interchangeably use the terms throughput , bandwidth and speed, and refer to a circuit as being a '64 k' circuit, or a '2 meg' circuit — meaning 64 ...
The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...
[1] [2] The backronym Packet InterNet Groper for PING has been used for over 30 years, and although Muuss says that from his point of view, PING was not intended as an acronym, he has acknowledged Mills' expansion of the name. [1] [3] The first released version was public domain software; all subsequent versions have been licensed under the BSD ...
The keepalive packet contains no data. In an Ethernet network, this results in frames of minimum size (64 bytes [2]). There are three parameters [3] related to keepalive: Keepalive time is the duration between two keepalive transmissions in idle condition. TCP keepalive period is required to be configurable and by default is set to no less than ...
