Consider the following scenario, in which a Web browser (lower) connects to a web server (above). There is no web cache in this question (so make sure you understand the difference between a browser cache and a web cache). Assume that the total Round Trip Time (RTT) propagation anqueueing delay between the browser and web server is 200 msec.HTTP serverHTTP browserwith browser cacheSuppose that the browser makes an HTTP request to the server for an HTTP object, that the browser has a copy of that object in its cache, but that copy may or may not be up-to-date in its cache (and so the browser requests the object using the HTTP If-Modified-Since header field). Assume that the time taken totransmit an HTTP reply (by the sender into the TCP connection) that contains a requested object in the body of an HTTP reply is 50 msec, but that the time taken to transmit a HTTP reply with a "304 Not Modified" reply code without an included object is negligible (e.g., zero). You can assume that a TCP connection haalready been set up, so do not include that delay in your answer below.What is the time from when the browser issues the initial HTTP GET request until it is able to display the requested object in the case that the browser does not have the requested object in its browser cache?O 100 msecO 250 msecO 300 msecO200 msecO 500 msecO 350 msecO 550 msec

As presented in the text, SMTP involves the exchange of several small messages. In most cases, the server responses do not affect what the client sends subsequently. The client might thus implement command pipelining: sending multiple commands in a single message. (a) For what SMTP commands does the client need to pay attention to the server's responses? (b) Assume the server reads each client message with gets() or the equivalent, which reads in a string up to a . What would it have to do even to detect that a client had used command pipelining? (c) Pipelining is nonetheless known to break with some servers; find out how a client can negotiate its use.
q9c- Context- Alice and Bob are members of the same Kerberos realm. They are both currently logged in with active session keys from the Kerberos KDC (key distribution centre). As per the Kerberos standard, the KDC has created unique session keys for both Alice and Bob, and then discarded them once received by the respective users. Alice wants to access a resource owned by Bob and contacts the KDC to request the necessary material. Answer the following questions about this scenario: Q- When Bob receives the service ticket from Alice, why should he trust her and what guarantees the service ticket is genuine and wasn’t forged by Alice?
Using the following snort rule as a model, write a rule that would detect all the packets shown (1-6): alert tcp any any -> any 80 (msg:"LOCAL my message"; content:"my content"; nocase; sid:1000110; rev:1;) Write a rule which will match all the following: 1. 64.12.10.32:8437 -> 204.126.133.22:80 GET /admin/scripts/setup.php 2. 64.12.10.47:8435 -> 204.126.133.22:80 GET /phpAdmin/Setup.php 3. 64.12.10.2:8439 -> 204.126.133.22:80 GET /php2-1- 10/siteadmin/login.php 4. 64.12.10.18:2173 -> 204.126.133.23:80 POST /admin/scripts/setup.php 5. 64.12.11.2:2174 -> 204.126.133.23:80 GET /php2-1- 10/admin/main/setup.php 6. 64.12.11.2:2176 -> 204.126.133.23:80 GET /ADMIN/PHP/SCRIPTS/login.ph e p Note: Full points are given only if your rule is precise and doesn't generate a lots of false positives. Answer:
What does it mean when an HTTP query has a header field of "Connection: keep-alive"? a. The client can keep the TCP connection open for future requests/responses if this is supported by the server. O b. Use UDP for additional connections to the server. c. Continually send an object from the server to the client until the client has acknowledged receipt of the requested object. O d. Use the QUIC protocol for this connection.
write a custom Snort rule to handle Inbound and Outbound HTTP traffic on the Private (Host-Only) network. Upload a screen shot of the Snort console displaying the alerts. In this exercise, we are going to create two Snort monitoring rules that will be used to alert on HTTPnetwork traffic for both Inbound and Outbound traffic. Remember, Inbound rules are those rules whosedestination is to your internal network (HOME_NET), outbound rules are directed out of your internalnetwork (!HOME_NET). When you use “any” there is no distinction on whether a rule is Inbound orOutbound. When using Inbound/Outbound to describe local traffic, traffic generated on the samenetwork (as in this lab on VMnet-1), the Inbound reference is to your client system that is running snortthe Outbound reference is to the HTTP server.You should now understand a little bit about custom rules, so given the following rule:alert tcp any any -> any 80 (msg:"TCP HTTP Testing Rule"; sid:1000004;)You should be able to…
Please solve it correctly and please provide explanation of your answers. Please answer parts g, h and i. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. g) The second segment from webserver was corrupted. So the PC…
Done in C for a network programming client and server in udp Develop a client and server responsible for a file transfer utilizing UDP. the client sends a local file to the server and the server will then reassemble and save the file locally. You must also account for the packets being re-ordered or being lost in transit to the server for when a connection drops for example. If a file is dropped, print a line to stderr for it. The client must be started by the command: ./client server.ip server.port mtu winsz in_file_path out_file_path An example for the server and client starting up is ./server 9090 0 ./client 10.10.0.1 9090 512 10 dir/file outfile
Question 23 A client's browser sends an HTTP request to a website. The website responds with a handshake and sets up a TCP connection. The connection setup takes 2.1 ms, including the RTT. The browser then sends the request for the website's index file. The index file references 8 additional images, which are to be requested/downloaded by the client's browser. Assuming all other conditions are equal, how much longer would non-persistent HTTP take than persistent HTTP? (Give answer in milliseconds, without units, rounded to one decimal place. For an answer of 0.01005 seconds, you would enter "10.1" without the quotes.)
C Programming: Write a program that optionally accepts an address and a port from the command line. If there is no address and port on the command line, it should create a TCP socket and print the address (i.e. server mode). You can choose any port number for your server (>1024). If there is an address and port, it should connect to it (i.e., client mode). Once the connections are set up, each side should enter a loop of receive, print what it received, then send a message. The ping from the client should be sent before entering that loop to start the process. Otherwise both sides will sit and listen without getting anything. The message should be ping from the client and a pong from the server. In order to test this on one machine, you will need to run the same program twice (in two separate terminals). Run first in server mode, then run in client mode using the information printed from the server as your command line arguments. This is the output it must print out: Running…

Computer Science Networks and should be done in C language. Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threads
6.7-2. Caching everywhere! We've seen caching used in many different places in our study of networking. In this question, you should match the description of a particular form of caching with the protocol or network service where this caching occurs. Each element of the pull-down menu should match with at most one of the given descriptions. Caching copies of web pages for an i client. individual Caching copies of web pages for a set of clients. Caching translation pairs between a domain name and an IP address Caching translation pairs between an IP address and a MAC address.
