following captured network traffic shows the three-way handshake to establish a TCP connection. Please write a TcpDump command running at the client side to capture all the packets with flag “S” only between the host “tclient.net” and the telnet server “telenet.com”. When check TCP flags, please use the format ‘tcp[tcpflags]&tcp-syn’, ‘tcp[tcpflags]&tcp-push’, ‘tcp[tcpflags]&tcp-ack’, and so on.

Write a snort rule to generate an alert for the following: search for the word “HTTP” in the first 20bytes of the payload of a packet that is originating in subnet (192.168.34.0/24) and going toyour subnet (192.168.56.0/24). The alert should read: “HTTP detected”. Could you please also include the nmap command used to scan the target?
Using tcpdump,read the packets from tcpdump.pcap and filter packets to include ip address 184.107.41.72 and port 80 only. Write these packets to a new file and md5sum that file. what is the md5sum shown?
8.4 One of the non-payload options in Snort is flow. This option distinguishes between clientsand servers. This option can be used to specify a match only for packets flowing in one direction(client to server or vice-versa) and can specify a match only on established TCP connections.Consider the following Snort rule:alert tcp $EXTERNAL_NET any -> $SQL_SERVERS $ORACLE_PORTS\ (msg: “ORACLE drop tableattempt:;\ flow: to_server, established; content: “drop table_name”; nocase;\classtype: protocol-command-decode;)a. What does this rule do?b. Comment on the significance of this rule if the Snort devices is placed inside or outside of theexternal firewall.
ABC Company needs to deploy an application through which incoming TCP packets are to be scrutinized according to the content type and the payload information it carries. While content types are explicitly available through the flag, payload contents are to be read and sorted. To sort this incoming TCP packets payload, identify the method and sort the payload accordingly. Imagine the inputs accordingly. Write a Code Using JAVA STREAM FILTER
Which one of the following statements is FALSE? File Transfer Protocol (FTP) is a TCP service that operates on ports 20 and 21. Telnet is a TCP service that operates on port 23. Simple Network Management Protocol (SNMP) is a TCP service that operates on port 25. Dynamic Host Configuration Protocol (DHCP) is a TCP service that operates on port 80.
What will happen during communication between TCP peers if either does not advertise it's Maximum segment size MSS value during handshake?
Given the topology below, write the commands to advertise the OSPFv3 networks on the Sohar router. Use the following requirements: - Enable IPv6 routing- Process ID 10 - Router IDs (Sohar router = 2.2.2.2) - Advertise Network address for each interface - LAN interface (G0/0) set to passive interface - Assign Link-Local Addresses (fe80::1) to G0/0
Which component of the IP header may be modified to make certain that a data packet will go through no more than N routers on its way to the location specified in the header?
Suppose a user has a webserver running at a machine with the name nadir.edu.net.pk and IP address 10.10.10.10. The authoritative DNS address for this web server is with the name dns.nadir.edu.net.pk and with IP address 11.11.11.11. Write all the steps involved in retrieving the IP address of nadir.edu.net.pk
A Wireshark trace of TCP traffic between hosts A and B indicated the following segments. Host A sent a segment with SYN flag set to B at time 0 seconds. Host A retransmitted the SYN segment at 1 second, 3 seconds, and 7 seconds. There were no further segments sent between A and B. At what time, did host A give up on getting a response from host B? ________seconds!
Hosts A and B have a TCP connection with neither side having any unacknowledged data. Now, host A sends two TCP segments back to back to host B. Host B sends an acknowledgement (ACK) for each segment. Host A receives the second ACK, but not the first one. How many packets does host A retransmit?
If a host has received the following segments in TCP:[1, 1000], [4001, 5000], [5001, 6000], [1, 1000]. (1)Show the contents of SACK option to be sent.
