The client responds with a segment containing ACK that is the response to the SYN sent by the server. To achieve that the server uses the SYN flag in the same way that the client did. The server also must initiate a response to the client. As I stated in the OP, smaller companies are going to contract out to an MSP which serves many clients, and most larger companies with in-house IT departments spread it across several sites.

The value of the ACK number field is the ISN + 1. synsynackack 0 points 1 point 2 points 8 months ago Most 'foot in the door' jobs absolutely require a drivers license in my experience. The client recognizes this as an acknowledgement that the server received the SYN from the client. In the first step, the client establishes a connection with a server. TCP handshake process, a client needs to initiate the conversation by requesting a communication session with the Server. FIN is used for terminating a connection. Because of this, the SYN/ACK packet from 10.223.100. The settings include Sequence Number, Maximum Segment Size, if SACK is permitted or not, Window Scale, Window Size etc. SYN-ACK is a SYN message from local device and ACK of the earlier packet. The acknowledgment number in the SYN/ACK packet in frame 3 should be 3839424769, but instead frame 3 has an acknowledgment number of 14744888. In another saying, they inform each other about what kind of settings they would like to use during the connection establishment.
The server must acknowledge the receipt of the SYN segment, so it sends a segment back with the ACK flag set. During 3-way handshaking both sides synchronize (SYN) and acknowledge (ACK) each other. The exchange of these flags is performed in three steps: SYN, SYN-ACK, ACK. The connection is full-duplex, and both sides synchronize (SYN) and acknowledge (ACK) each other. TCP uses a three-way handshake to establish a reliable connection. The ISN is randomly chosen and is increased by one for each byte of data sent from the client to the server. The ACK flag is always set, except for the first segment of a TCP connection establishment. This value is known as the initial sequence number (ISN). The client begins the three-way handshake by sending a segment with the synchronize sequence number (SYN) control flag set, which indicates an initial value in the sequence number field. synsynackack 0 points 1 point 2 points 8 months ago Most 'foot in the door' jobs absolutely require a drivers license in my experience.
