bandwidth hogs on network

Today's computers are getting faster and faster, and dual-core, three-core, and quad-core computers are already common. Now there is a lot of memory, 2 GB/4 GB is normal, but the network is still very slow!2 Mbit/s/4 Mbit/s. What balance do you have in your mind when the computer is so slow? If your community can find multiple wireless networks, then...Today, we will teach you how to turn your computer into a wireless router using virtual machine tech

When we are lazy, we will say that the network bandwidth is 10 MB. Do not assume that the maximum download traffic can reach 10 MB of files downloaded per second. It is actually 10/8 = 1.25 MB. The reason is that the bandwidth unit is different from the hard disk unit. Misunderstanding: whether KB is equal to KB I often encounter such a problem. If we clearly

Background information: In debugging the network, often need to detect the maximum bandwidth between the two hosts, I have been using the Iperf command, the effect is very good and accurate, but found some Yun-wei friends do not know that there is this tool, so intend to write a brief introduction to the article. Specific actions: Operating system: CentOS6.5 x86_64 MinimalServer:192.168.10.11192.168.10.1

Prevent users from using PHP code DOS to consume network bandwidth. Use PHP code to call sockets and directly use the server's network to attack other IP addresses. the common code is as follows: Copy the code as follows: $ packets0; $ ip $ _ GET [ip]; $ rand $ _ GET [port]; set_ti uses PHP code to call sockets and directly uses the server's

This article describes some of the Linux command-line tools that you can use to monitor network usage. These tools can monitor data transmitted over a network interface and measure the speed at which data is being transmitted. The inbound traffic is displayed separately from the outbound traffic.Some commands can show the bandwidth used by a single process. This

Use PHP code to call sockets, directly with the server network attack other IP, the common code is as follows: Copy the Code code as follows: $packets = 0;$ip = $_get[\ ' ip\ ');$rand = $_get[\ ' port\ ');Set_time_limit (0);Ignore_user_abort (FALSE);$exec _time = $_get[\ ' time\ ');$time = time ();Print \ "Flooded: $ip on port $rand\";$max _time = $time + $exec _time;for ($i =0; $i $out. = \ "X\";}while (1) {$packets + +;if (Time () > $max _time) {Br

What is Nethogs? Nethogs is an open source command-line tool (similar to the Linux top command) for real-time statistics of network bandwidth usage by process or program. From Nethogs Project website: Nethogs is a small ' net top ' tool that does not slow down each protocol or the speed of each subnet, as most tools do, but to group bandwidth by process. Net

When IIS is enabled, the outbound bandwidth of the server is used up. that is to say, the server continuously sends packets to others. this is different from the DDOS attack. DDOS constantly receives a large number of packets. use PHP code to call sockets and directly use the server's network to attack other IP addresses. the common code is as follows: The code is as follows: $ Packets = 0; $ Ip = $ _ GET

But when the bandwidth of our servers or VPS is heavily occupied or full, there is no satisfactory tool or program to see how much

Nload is a simple and easy-to-use bandwidth flow monitoring tool under Linux, and dynamic graphics based on character interface display the current traffic of the NIC.
