How to limit upload and download to all users in network using mikrotik RouterOS
There are two ways how to make this: using mangle and queue trees, or, using simple queues.
1. Mark all packets with packet-marks upload/download: (lets constider that ether1-LAN is public interface to the Internet and ether2-LAN is local interface where clients are connected
/ip firewall mangle add chain=prerouting action=mark-packet in-interface=ether1-LAN new-packet-mark=client_upload
/ip firewall mangle add chain=prerouting action=mark-packet in-interface=ether2-WAN new-packet-mark=client_download
2. Setup two PCQ queue types – one for download and one for upload. dst-address is classifier for user’s download traffic, src-address for upload traffic:
/queue type add name=”PCQ_download” kind=pcq pcq-rate=64000 pcq-classifier=dst-address
/queue type add name=”PCQ_upload” kind=pcq pcq-rate=32000 pcq-classifier=src-address
3. Finally, two queue rules are required, one for download and one for upload:
/queue tree add parent=global-in queue=PCQ_download packet-mark=client_download
/queue tree add parent=global-out queue=PCQ_upload packet-mark=client_upload
If you don’t like using mangle and queue trees, you can skip step 1, do step 2, and step 3 would be to create one simple queue as shown here:
/queue simple add target-addresses=192.168.0.0/24 queue=PCQ_upload/PCQ_download packet-marks=client_download,client_upload

VMware ESX Command line Management
This documentation describes the concepts, tasks, and commands that you use to administer your virtual environment through the command line. vSphere provides several command-line interfaces that you can use to automate common tasks that you perform to deploy and support your virtual datacenter. For example, you can use vSphere command-line actions to configure and manage storage for the ESXi hosts in your datacenter, set up networking for virtual machines, perform virtual machine power operations, monitor hosts, and many other activities

I am very impressed by the collective smarts of the security community and I highly recommend reading the whole list and investigating any tools you are unfamiliar with. Click any tool name for more details on that particular application, including the chance to read (and write) reviews. Many site elements are explained by tool tips if you hover your mouse over them.

how to know who is accessing your files
ShareWatch allows you to see who is connected to a computer and what files they are accessing. Have you ever wondered why your hard drive or modem is active, but you aren’t doing anything to cause it to be active? It is possible a remoteuser is accessing your computer. Have you ever had a file locked but you don’t know why? ShareWatch can tell you if a network user is using the file and allows you to disconnect them so that you can edit/delete the file. Have you ever wanted to shutdown a computer, but don’t want to drop people using the
computer. ShareWatch will show you all resources in use by remote users.
