- On a basic Linux server following services are required Assign a dynamic IP address to a client on interface eth0 Find out the path of the packet to the server on (172.16.10.19), put your system in promiscuous mode. Apply forsetgid and sticky permissions on /home/Ali/programming Rename file present on Desktop from “file.txt” to “newfile.txt” Find out the number of IP addresses used by google.com Display all user accounts and groups in a Ubuntu system Display all files in /opt/ starting with s and have a .txt extension.Perform the following tasks: a) Write the command to install ssh on Ubuntu.

Give the appropriate example. How to start/stop/restart SSH service on Ubuntu. LinuxYou have successfully configured Windows Server 2019 as a VPN server using SSTP tunnel type. You allowed another user to dial-in to the server. The user reported that there wasn't any ask for credentials and they were connected automatically with the current user account. How can you explain this behaviour? The VPN profile is has“UseWinlogonCredential” parameter enabled. The admin added machine certificate on the client computer. The admin added user certificate on the client computer. The admin enabled VPN roaming profile on the client computer.
- The following program sets up a single client/server connection. When the client connects, the server reads any incoming data as text and prints it out one line at a time. If the server receives the string “shutdown”, then it closes the socket and exits. Download this program Download this program into GCC and run the code. Then update your code to allow for the server to manage concurrent connections on the same port. Use IP address 127.0.0.1.

Which of these would BEST describe this option?Only specific MAC addresses will have access to the networkCertain URLs will be blocked at the firewallAll wireless data will be encryptedInbound connections can be opened without any explicit rulesThe wireless network will not be visible in selection menusEither Windows VM and Either Linux VM Use your knowledge of the 1) Windows Commandl-line and 2) Linux Shell to write a simple script which creates a running log that documents each VM devices network status. The scripts should do the following: 1. The script should create a directory tempinfo in your current working directory 2. It should then capture ALL of the IP configurations on the system and add them to a file called myIPhealth.txt inside of the tempinfo directory 3. It should then perform network check (ping) to determine if the device's network card can communicate. These results should also be added to the myIPhealth.txt file.
- Can you provide some explanation and steps to do , i am using ubuntu20.04 on windows 10 VMware. also i could able to config VPN connection to the server what is next step also i would like to use python for programming. task description is below. Thanks A UDP service FlagServ is running at flagserv.cse543.rev.fish:13337. This UDP service receives a target IP address from the user, and if the user is authenticated, it will happily send a flag (a special string) via UDP to port 13337 of the target IP. Your job is to write a program that retrieves the flag. FlagServ employs THE BEST AUTHENTICATION METHOD IN THE WORLD: Source-IP-based authentication, which means it authenticates all users based on their source IP addresses. If a user's source IP address is trusted, FlagServ will send out the flag to the specified destination (repeat: via UDP). Otherwise, it will send an error message back to the untrusted user (via UDP, too). The only trusted IP is 10.2.4.10. Your task is to break or…Linux: 1.
