destination host is too busy to respond. In this case, you can try to ping the hosts on the other LAN. If the timeout does not exist during the ping process, then the local connection is good and you need to troubleshoot the problem host.The situation is as follows PING 192.168.128.1 (192.168.128.1): Data bytes Bytes from 192.168.128.1:icmp_seq=0 ttl=64 time=3.255 msBytes from 192.168.128.1:icmp_seq=1 ttl=64 time=0.897 msRequest Timeout for icmp_seq 2Request Timeout for icmp_seq 3B

The user's current network is available: WiFi, 2g/3g Network, users open and not open the network, and whether can be used is not the same thing. Can use refers to: users open the network and can connect to the Internet for Internet access.To detect if the current network is

General operating system performance mainly related to the main problems are: Processor usage, memory footprint, disk i/0 operations, and network traffic.To view Windows performance, in most cases through Windows Task Manager, you can eject task Manager by typing: taskmgr in the command line. Task Manager can view: CPU usage, memory usage, and network traffic.Using Windows Task Manager is intuitive and the

The Linux test tool tcpdump command is used to monitor TCP/IP connections and directly read data headers at the data link layer. You can specify which data packets are monitored and which control formats are to be displayed. For example, we want to monitor the communication between all Ethernet and execute the following command: tcpdump-ieth0, let's take a look at the specific content. Even in a relatively

IOS gets the network status, and ios gets the network For iOS developers, obtaining the network status is often used. -(NSString *) getNetWorkStates {UIApplication * app = [UIApplication sharedApplication]; NSArray * children = [[app valueForKeyPath: @ "statusBar"] valueFor

The iPhone determines the current network connection status, and the iphone current network connection Import header files #include Determine the network connection status // Determine the current network connection

developed to assist in TCP Parameter Optimization, but here we do not want to study the TCP Window Scale and maximum segment length, because this is not the focus of our current discussion. However, when testing a high-throughput AP, you may find it necessary to tune TCP parameters so that you can get a larger throughput on each iPerf client-For details, see DrTCP.

Timer is used to monitor whether the network is pinged and timer is pinged. The project needs to connect to a specific server. If the server cannot be connected, the system prompts in real time to start using Timer for real-time detection. Void timer_Tick (object sender, EventArgs e) {Ping pingSender = new Ping (); PingReply reply = pingSender. Send ("192.168.1.104", 1000); if (reply.

Network Monitor 3.4 is a free grab kit from Microsoft that assists administrators in crawling client or server-side access and interaction information to help troubleshoot problems.This article shares how this tool gets, installs, and grabs the package.First of all, this tool can be downloaded from Microsoft's website, as follows.Download Microsoft Network

Nethogs is a small, free open source command-line tool used to count network bandwidth usage in real time by process or program.For use similar to "repo tool", "Depot_tools" and other tools checkout source code is very useful, you can view the current download speed information, so you do not blindly wait.Installation under Ubuntu system sudo apt-get install Nethogs How to use Nethogs [-d] [-h] [-P] [-t] [-v] [device (s)]

Through the/proc/net/dev can be viewed to the network card traffic, according to the changes in the value of the file in conjunction with while loop write a real-time monitoring network card script, by specifying the network card name as parameters to monitor the traffic of the specified

Cacti is a set of graphical analysis tools for network traffic monitoring based on PHP, MySQL, SNMP and RRDtool. If you want to use CACTI to monitor the Linux server's network card traffic, you need to install Net-snmp-utils-related packages on the monitored Linux servers, and we can install them via yum online, for example:After the net-snmp-utils is installed,

There are many open-source network monitoring tools for Linux systems. For example, you can use command iftop to check bandwidth usage. Netstat is used to view the interface statistics report and the current running process of top monitoring system. But if you want to find a tool that can count network bandwidth utilization in real time, then Nethogs is worth a look.Nethogs is an open source command-line to

user. 3. Create a monitoring site Assume that the monitored server is named "test host", the IP address is 192.168.100.110, And the SNMP community is public. Go to the console panel of cacti-> Click "devices" to enter the device panel-> Click "add" to add a new device.-> Fill in the information of the server to be monitored. Select "local Linux machine" or "UCD/net snmp host" for the host template (select a proper host template)-> Click "CREATE" to save the information. If there is no proble

, which are exactly what we Configured the scheduled task to do.Since We know the alert would always send the same values in the same order, i.e. name, date, counter, threshold, and value , we can just pull them from the command line arguments based on position and pass them to the SendMail () function.Note that there is more robust ways to process command line arguments, and this should is sufficient for your purposes. Send email alert from performance

How to monitor network usage through nload in Linux Nload is a free software tool for linux. It provides two simple graphics to help linux users and System Administrators monitor network traffic and bandwidth usage in real time. One is incoming traffic, one is outbound traffic. I really like to use nload to display the

Nethogs is an open source network traffic monitoring tool that shows the bandwidth usage of each process, which makes it more intuitive to use the network. Nethogs supports IPV4 and IPV6 protocols, supports local network cards, and PPP links.Where the PID column shows the program's process number, the user column shows the program's owner, the program column show
