What three packets are exchanged between two hosts when establishing a tcp connection?
The SYN packet, the SYN ACK packet , And ACK packet
When a syn packet is sent what are the three most common responses?
SYN-ACK, ACK and RST
What is the purpose of SYN bit in a TCP header?
In order to begin the handshake process, the client sends a SYN packet to the server. This is required to establish a synchronization with the server in order to ensure that both the client and the server will maintain and keep their exchange of packets in the right order. In order to complete the "handshake," the reponse from the server will be an ACK packet.
Host 1 sent a syn packet to host 2 what will host 2 send in response?
This is used at transport layer of OSI for connection oriented services. Its three way handshake. 1) SYN 2)SYN-ACK 3)ACK hence SYN-ACK is the answer.
What is 'intent' in Latin?
As an adjective (syn. "eager, earnest"): intentusAs a noun (syn. "aim, purpose"): propositum, destinatum
What is the purpose of the update packet?
The packet is sent to discover neighbors within the EIGRP network.
What is a description of the 3-way handshake?
The following steps explain how the 3-way handshake works. A host or client asks a server if it is open for a connection by sending a SYN data packet over the IP. If there is an open port for a new connection, the server sends an ACK packet to acknowledge the request. On receiving the ACK packet, the client sends back an ACK packet to establish the connection.
How can you get the gas out of a packet of crisps?
The packet must be punctured. That lets the gas out, but of course makes it possible for air to get into the packet at any time after that. The original purpose of the gas was to avoid this. The least messy way to puncture the packet is with the point on the end of a pin.
What purpose does the acknowledgement number in TCP do?
It acknowledges receipt of the previous packet in the sequence.

What are some weaknesses of a packet-filtering router?
The weaknesses of static (or stateless) packet filters and stateful packet filters are different in a few ways. Stateless packet filters frequently block SYN scans of networks, but .... Stateless packet filters. (cf. iptables connection tracking), cf. state vs. stateless discussion. confounded application layer protocols like FTP, H323 Because of the nature of connection tracking and state awareness, stateful packet filters are vulnerable to resource exhaustion and deliberate attempts to trip rate-limiting features.
What is handshaking in networking?
A handshake in networking happens when a computer wants to talk to another computer. Before anything is sent and received the hand shake takes place. This example is from the TCP protocol: Machine 1 sends a SYN packet to Machine 2 Machine 2 sends a SYN/ACK back to Machine 1 Machine 1 sends an ACK back to Machine 2 SYN = Synchronise ACK = Acknowledge
