Which repository should you install before installing the nginx web server?

Answers

Answer 1

Before installing the nginx web server, it is recommended to install the EPEL (Extra Packages for Enterprise Linux) repository. The EPEL repository provides additional packages that are not included in the default repositories of the operating system, which are needed to run some software, including nginx.



The EPEL repository contains various packages that are commonly used in a production environment, such as development tools, libraries, and web servers. It is available for CentOS, RHEL, and other related distributions.

To install the EPEL repository, the command may vary depending on your operating system and its version. For example, on CentOS 7, you can install the EPEL repository by running the following command:

sudo yum install epel-release

On RHEL 7, you can install the EPEL repository by running the following command:

sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Once the EPEL repository is installed, you can proceed with installing the nginx web server by running the appropriate command for your operating system, such as:

sudo yum install nginx (on CentOS)

sudo dnf install nginx (on Fedora)

sudo apt-get install nginx (on Debian/Ubuntu)

In summary, it is recommended to install the EPEL repository before installing the nginx web server to ensure that all necessary packages are available and up-to-date.

What are the major differences between message-passing and shared-address space computers? Also outline the advantages and disadvantages of the two.

Answers

Message-passing and shared-address space computers are two different approaches to interprocess communication in distributed systems.

Message-passing is a method of communication where processes exchange messages with each other. Each process has its own private memory space, and communication occurs through message passing. The sender process creates a message, and the receiver process retrieves the message. This type of communication is often used in distributed systems where processes are distributed across multiple nodes and cannot share memory.

On the other hand, shared-address space computers are systems where multiple processes share the same physical memory. Each process has its own private memory space, but all processes can access a shared memory region. This type of communication is often used in parallel computing where multiple processes are executing on the same computer.

The major differences between message-passing and shared-address space computers are as follows:

1. Message-passing requires explicit communication between processes, whereas shared-address space computers allow processes to communicate implicitly through shared memory.

2. Message-passing is often used in distributed systems, whereas shared-address space computers are often used in parallel computing.

3. In message-passing, processes do not have direct access to each other's memory, whereas in shared-address space computers, processes can access each other's memory through shared memory.

The advantages of message-passing are:

1. Message-passing is easier to implement in distributed systems.

2. Message-passing provides better fault tolerance because processes are isolated from each other.

3. Message-passing allows for greater security because processes cannot access each other's memory.

The disadvantages of message-passing are:

1. Message-passing can be slower than shared memory communication because of the overhead associated with message passing.

2. Message-passing requires more memory because each message must be stored in memory.

The advantages of shared-address space computers are:

1. Shared-address space computers can be faster than message-passing because processes can access each other's memory directly.

2. Shared-address space computers can be easier to program because processes can communicate implicitly through shared memory.

3. Shared-address space computers can reduce memory requirements because shared memory is used instead of message passing.

The disadvantages of shared-address space computers are:

1. Shared-address space computers are less fault-tolerant because processes can directly access each other's memory.

2. Shared-address space computers can be less secure because processes can access each other's memory.

A hacker uses port 25 as the client post on his/her end to attempt to open a connection to your Web proxy server using the following rule set. Rule Direction Src Addr Dest Addr A In External Internal B Out Internal External с Out Internal External D In External Internal E Either Any Protocol TCP TCP TCP TCP Any Src Port Dest Port >1023 25 25 >1023 >1023 25 25 >1023 Any Any Action Permit Permit Permit Permit Deny Any a. The following packets might be generated. Explain why this attack will succeed, Packet Direction Src Addr Dest Addr Protocol Src Port Dest Port Action 7 In 10.1.2.3 172.16.3.4 TCP 25 8080 ? 8 Out 172.16.3.4 10.1.2.3 TCP 8080 25 ? b. When a TCP connection is initiated, the ACK bit in the TCP header is not set. Subsequently, all TCP headers send over the TCP connection have the ACK bit set. Use this information to modify the rule set.

Answers

Based on the rule set provided, the hacker is attempting to use port 25 to connect to the Web proxy server.

The rule set allows traffic from external sources (Direction A) with a source address of any (Any Src Addr) and a destination address of the internal Web proxy server (Dest Addr Internal) using TCP protocol with a source port greater than 1023 and a destination port of 25.

Outbound traffic (Direction B) is permitted from the internal network to external sources (Dest Addr External) using TCP protocol with a source port of 25 and a destination port greater than 1023. Any traffic that matches these criteria is permitted (Action Permit).

The packets in question are as follows:

Packet 7: Inbound traffic with a source address of 10.1.2.3 (external), a destination address of 172.16.3.4 (internal Web proxy server), using TCP protocol with a source port of 25 and a destination port of 8080. The action for this packet is not specified in the rule set, so it is unclear whether it is permitted or denied.

Packet 8: Outbound traffic with a source address of 172.16.3.4 (internal Web proxy server), a destination address of 10.1.2.3 (external), using TCP protocol with a source port of 8080 and a destination port of 25. The action for this packet is not specified in the rule set, so it is unclear whether it is permitted or denied.

Based on this information, it is possible that the attack will succeed. The hacker is attempting to use port 25 to connect to the Web proxy server, and the rule set allows traffic using TCP protocol with a destination port of 25. However, it is unclear whether the packets in question are permitted or denied by the rule set, so further analysis is needed to determine the success of the attack.

To modify the rule set to improve security, the ACK bit in the TCP header can be used to ensure that only legitimate TCP connections are allowed. One way to do this is to add a new rule that requires the ACK bit to be set in all incoming TCP traffic. This can be done by modifying Rule A to specify that only TCP traffic with the ACK bit set is permitted. The modified rule set would look like this:

Rule Direction Src Addr Dest Addr Protocol Src Port Dest Port TCP Flags Action
A In External Internal TCP >1023 25 ACK Permit
B Out Internal External TCP 25 >1023 - Permit
C Out Internal External TCP >1023 25 - Permit
D In External Internal TCP 25 >1023 ACK Permit
E Either Any TCP Any >1023 ACK Permit

This modified rule set ensures that only TCP traffic with the ACK bit set is allowed in both inbound and outbound directions. This can help prevent malicious TCP connections from being established, improving overall network security.

You are using fast 8-bit pwm with a 1 clock prescaler on timer 1. channel B. You want to generate a hitime of 0.0023 milli-seconds. What value should you set OCR1B Your Answer: Answer

Answers

The value to set OCRB for a hitime of 0.0023 milliseconds using fast 8-bit PWM with a 1 clock prescaler on timer 1, channel B is 37.

How to calculate

To calculate the value to set OCR₁B for a hitime of 0.0023 milliseconds using fast 8-bit PWM with a 1 clock prescaler on timer 1, we need to use the following formula:

hitime = (OCR₁B + 1) ×(1 / f_pwm) ×prescaler where f_pwm is the frequency of the PWM signal, which is equal to the frequency of the timer clock divided by the prescaler.

For an 8-bit timer with a 1 clock prescaler, the timer clock frequency is equal to the CPU clock frequency (F_CPU).

Therefore, f_pwm = F_CPU / prescaler = F_CPU.

Substituting the values given in the question, we get: 0.0023 ms = (OCRB + 1) ⨯ (1 / F_CPU)

Solving for OCR₁B, we get:

OCR1B = (hitime ×F_CPU) - 1

Plugging in the values, we get:

OCR1B = (0.0023 ×F_CPU) - 1

Assuming a CPU clock frequency of 16 MHz, we get: OCR₁B = (0.0023 × 16e6) - 1 OCR₁B = 36.8

Since OCR₁B must be an integer value, we round up to the nearest integer and set OCR₁B to 37.

Therefore, the value to set OCR₁B for a hitime of 0.0023 milliseconds using fast 8-bit PWM with a 1 clock prescaler on timer 1, channel B is 37.

According to the information presented in the video, the telephone system is an example of a circuit-switched network. In a circuit-switched network, a dedicated communication channel is established between two endpoints for the duration of their communication.

In the case of the telephone system, the network establishes a connection between two parties by allocating a dedicated line between them for the duration of the call. This ensures that the parties can communicate with minimal delay or interference, but it also means that the resources used by the dedicated line are unavailable to other users while the call is in progress. Circuit-switched networks were the dominant form of communication networks in the early days of telecommunications. However, with the advent of digital communication technologies and the internet, packet-switched networks have become more prevalent. In a packet-switched network, data is divided into packets and transmitted over a shared network, with each packet being independently routed to its destination. This allows for more efficient use of network resources and greater flexibility in communication, but it also introduces some overhead and potential delay due to the need for packet routing and reassembly.

This next problem is going to deal with checking if someone inputs a string with a few requirements. Imagine you are prompted to input a password, but the password needs to have include uppercase and a number. In order to do this, you must look at each char in the string and Booleans to indicate certain criteria are met. Since there are 3 criteria, you should have 3 Boolean variables. The rules for the password are: • Must contain at least 8 chars • Must contain 1 uppercase letter • Must contain 1 digit • There are no restrictions with lowercase letters or special chars When considering where to use Booleans, think of it as a "flag", for each criteria. If you meet the length requirement, then the flag would change from FALSE to TRUE. Once all the flags are true, you will have a valid password. Tip: The ASCII table can be used to determine the numeric value of a particular char. You may want to create ranges of these numerical values for each criteria.

Answers

The requirements that meets user's input string are length, uppercase letters, and numbers.

Specifically, the password must contain at least 8 characters, at least 1 uppercase letter, and at least 1 digit.
To check these requirements, you can use Boolean variables as "flags" for each criteria. For example, if the password contains at least 8 characters, you can set a Boolean variable to true to indicate that this criteria has been met. Similarly, if the password contains an uppercase letter or a digit, you can set other Boolean variables to true.
To determine whether a character in the password is an uppercase letter or a digit, you can use the ASCII table to find the numeric value of that character. Then, you can create ranges of these numerical values to check whether the character meets the criteria for an uppercase letter or a digit.
Once all three Boolean variables are true, you can consider the password to be valid.

Overall, this approach allows you to use Boolean variables and the ASCII table to check whether a user's input string meets certain requirements.

What does it mean if the ttl expires for a packet?

Answers

A packet is sent across a network, it is assigned a Time-to-Live (TTL) value. This value is set by the sender and determines how many network hops the packet can make before it is discarded. Each time the packet passes through a router or network device, the TTL value is decremented by one.

If the TTL value reaches zero before the packet reaches its destination, the packet is discarded and an error message is sent back to the sender. This error message is called a TTL expired message.There are a few reasons why a TTL value might expire for a packet. One reason could be that the packet is stuck in a routing loop, where it keeps getting forwarded between the same routers without making any progress towards its destination. In this case, the TTL value would be decremented each time the packet passes through the loop, eventually reaching zero.Another reason why a TTL value might expire is if the packet is taking too long to reach its destination. If the network is congested or there are other delays along the way, the packet might not make it to its destination before the TTL value runs out.In summary, if the TTL value expires for a packet, it means that the packet has exceeded the maximum number of network hops allowed and has been discarded. This could be due to a routing loop or delays in the network.

in what type of exploitation does an attacker steal a valid session id and use it to get into the system to extract data?

Answers

The type of exploitation in which an attacker steals a valid session ID and uses it to gain access to a system and extract data is known as session hijacking.

In this type of attack, the attacker intercepts the session ID of an authenticated user and then uses it to impersonate the user and access sensitive information. To prevent session hijacking, it is important to use secure session management techniques such as regularly changing session IDs and implementing strong encryption and authentication measures.The type of exploitation where an attacker steals a valid session ID and uses it to gain access to the system and extract data is known as "Session Hijacking".Session hijacking is a technique used by attackers to steal an authenticated user's session ID, which is often stored in a cookie or URL parameter, and use it to impersonate the user and perform unauthorized actions on the system.

Suppose that Malice is attempting to guess the password for a smartphone taken from Alice. Through research, Malice knows that the password is a total of 9 characters, where each character can be an English upper or lower case letter or a digit from 0 to 9 inclusive. Malice was able to obtain the first 2 characters in the password by posing as a maintenance repair worker at Alice's workplace to observe her (using social engineering), but does not have the remaining characters.
a) Showing all steps, calculate and show the password search space of the remaining portion of this password Malice is attempting to obtain. Also, explain how this password should be stored in Alice's smartphone, for best security?

Answers

The password search space for the remaining portion of the password is approximately 3.5 x 10^13 possible combinations. For best security, a strong and unique password should be used that is difficult to guess or brute-force.

The password search space for the remaining 7 characters is the total number of possible combinations of upper and lower case letters and digits raised to the power of 7. This is calculated as follows:

There are 62 possible characters for each of the 7 remaining characters (26 upper case letters + 26 lower case letters + 10 digits = 62).

Therefore, the password search space is 62^7, or approximately 3.5 x 10^13.

This password should be kept as a salted hash on Alice's smartphone for maximum security. Salt is a random value that is added to the password before hashing to make it more difficult to crack for attackers. Both the salt and the hashed value should be saved in the smartphone's memory separately. Even if an attacker has the hashed password, they will still need to know the salt value to break it.

Additionally, the hash function used should be a strong one-way hash function, such as bcrypt or script, to further increase the difficulty of cracking the password.

the big win for quicksort over mergesort is that it runs in place. true or false

Answers

Yes, the above statement is true. One of the big advantages of quicksort over mergesort is that it operates in place, meaning that it doesn't require additional memory space to sort the elements.

A divide-and-conquer algorithm is a quicksort. It operates by choosing one element from the array to serve as the "pivot," and then dividing the remaining components into two sub-arrays based on whether they are less than or greater than the pivot. It is referred to as partition-exchange sort for this reason.

Merge sort, which is also sometimes spelled mergesort, is a general-purpose, effective sorting algorithm used in computer science. The logical sequence of equal elements is identical in the input and output for the majority of implementations, which results in a stable sort.

Approximately how many songs could the first ipod hold?

Answers

The first iPod was released in 2001, and it had a storage capacity of 5GB. This might not seem like much today, but at the time, it was a significant amount of storage for a portable music player.

To put it into perspective, 5GB is enough to hold approximately 1,000 songs, assuming that each song is about 5MB in size. Of course, this is just an estimate, as the size of songs can vary depending on factors like the length, bit rate, and compression.It's worth noting that the first iPod wasn't the first portable music player on the market. However, it was the first one to use a hard drive instead of flash memory, which allowed it to store a lot more music. Prior to the iPod, most portable music players had a capacity of around 64MB or 128MB, which meant that they could only hold a handful of songs.Over the years, the storage capacity of iPods has increased significantly, with the latest models able to hold up to 256GB of music. However, the first iPod remains an important milestone in the history of portable music players, as it paved the way for the digital music revolution that we take for granted today.
