$ sudo iftop-n
The n option prevents Iftop from resolving IP addresses to host names, and parsing itself can bring additional network traffic.Installing Iftop:ubuntu/debian/fedora users can obtain it from the default

Programming | Network talk about socket programming, we may think of QQ and IE, yes. There are many network tools such as Peer-to-peer, NetMeeting and other applications implemented in the application layer, but also with the socket to achieve. The socket is a network programming interface that is implemented at the network

Switch selection criteria in Network Monitoring
With the increasing use of high-definition cameras, how to choose a suitable switch to monitor the overall network architecture performance has become a very important role in the early design of the high-definition monitoring system and project quotation. A proper switc
Recently, the company has been developing remote video and remote monitoring projects. We just have time to summarize them,
I don't know much about it, just follow the feeling;
Query a lot of information, all scattered, some good information on foreign websites,
Many of them are implemented using C and C ++. I have limited technical skills and can only use C !!

is, the response-based solution. What's worse, this problem usually comes from complaints from end users, which undoubtedly raises questions about the work of the IT department.
In addition to the obvious public relations, this response-based problem solution is very inefficient. If the problem is detected early, it takes only a few minutes to solve the problem, but if it is found late, it will waste more time. For example, if it is found early, the log can solve the problem of insufficient dat
