- please help me to solve this simple operation of paython 3- spam = 'This is a computer.'spam[2:7]: spam[7:]: len(spam):Write a complete bash script that monitors who logs in and logs out of the current CSELinux machine (e.g., cse01, cse02, etc.) where the script is running. In particular, youwill check the status of who is logged in every 10 seconds and report each user ID thatlogs in or logs out during that time frame. Note that there may be more than one userthat logs in or out duringthis interval. You must include the host name when reportingthe user ID information. In addition, you will install a custom signal handler to trap theSIGINT(i.e.,^C)onetimebeforeyouareabletoterminatethescriptwiththeSIGINT.You will also print out the current date and time and report the number of users loggedin,even if there are no changes (i.e.,no one logged in or out during the interval). HOW TO DO THIS? PLEASE EXPLAIN WITH ANSWER!!You have already made a file that can be used to hit the target server with a dictionary attack even if salt is not used. If you take out the word "impossible," the file has 171,000 words from the OED. The dictionary is now out of date because the 32-bit salt server was changed. You want to make a new dictionary so you can use raw force to find words in an existing one. How many words are in the new book all together?

Note that there may be more than one userthat logs in or out duringthis interval. You must include the host name when reportingthe user ID information. In addition, you will install a custom signal handler to trap the SIGINT(i.e.,^C) one time before you are able to terminate the script with the SIGINT.

PLEASE EXPLAIN WITH ANSWER!!2. Describe the flaw in this argument: Consider the following attack against one-time pad: upon seeing a ciphertext c, the eavesdropper tries every candidate key k e {0,1}^ until she has found the one that was used, at which point she outputs the plaintext m. This contra- dicts the argument in the book that the eavesdropper can obtain no information about m by seeing the ciphertext.Write a short bash script to count the number of blank lines in a file or from stdin. you are not allowed to use the -c/--count option of grep in your solution or awk/sed unfortunately. how it'll function:numblank [-q] [FILE...]• the option -q (for quiet):– if supplied, counts are not printed out;– exit status alone is used to return info (see below);– must be the first command-line argument to numblank if supplied;2• [FILE...] indicates that one or more file names/paths may be supplied, but all are optional: – if no FILE arguments are supplied, the program is to read from standard input, and print out a single line containing only the count of the number of blank lines found – if a single FILE argument is given, the program is to print a single line containing only a count of the number of blank lines found;– if multiple FILE arguments are supplied, counts for each file are to be printed on some example calls: numblank foo1 foo2 foo3 ⇒foo1:5foo2:0foo3:23• numblank -q foo ⇒(no output)•…
- A certain university is considering the purchase of N95 masks to distribute to their students for protection against the next variant of the covid virus. They found a reliable distributor who offers N95 masks with a quantity discount. The pricing is shown below. Number of N95 masks Price per mask From To 500 $1.23 501 2000 $0.98 2001 5000 $0.62 5001 or more $0.53 For example, if the university purchases 700 masks the price is 500 × $1.23 = $615.00 for the first 500 masks plus (700 – 500) × $0.98 = $196.00 for the next 200 masks for a total of $615.00 + $196.00 = $811.00. Write a MATLAB program that first prompts the user to input the number of masks. Use the following prompt: Please enter the number of N95 masks: Then, based on the number entered and the above table, calculate the purchase price. Output to the command window the number of masks and the purchase price as follows: Your price for xXXx N95 masks is $xxx.xx where xxxx is the number of masks and $xxx.xx is the price. If the…Prior to now, you had created a file to utilize in a dictionary attack against a target server that didn't use salt. With the exception of "impossible," this file's 171,000 words cover the whole of the OED. The dictionary can no longer be used as a result of an update to the 32-bit salt server. In order to use brute force to search through an outdated vocabulary, you want to create a brand-new one. How many entries does the new dictionary have in total?In this project, you are required to do socket programming in C language (Linux environment) to implement a pair of client and server that can achieve simple password verification to indicate the current market value of the stock.
