a powerful tool for viewing network port traffic in Linux--SARThere is a small tool that allows you to view IP packet traffic statistics for each network port. With the SAR command, plus the-n dev parameter, you can count the traffic on all network cards, in the fifth and si
configurable UDP port on a Windows host. Some common security defects are not considered. Some services such as snmp, tftp, and NFS use UDP protocol. Unfortunately, UDP scanning is sometimes very slow because most hosts limit the proportion of ICMP error messages (recommended in RFC1812 ). For example, in the Linux kernel (in net/ipv4/icmp. in h文) only 80 ICMP messages that cannot be reached by the target

tcpdump-I eth1 pppoes-W/tmp/xxx. the CAP is separated by a size of 100 MB to save the file. If the size of the CAP is greater than 10000 MB, an additional file-C 10000 m is opened to capture packets and then exit-C background to capture packets. The exit of the console will not affect the file: nohup tcpdump-I eth1 port 110-W/tmp/xxx. cap
You can use ethereal or Wireshark to open the captured file.

Port Scanning aims to identify which ports in the target system are enabled and which services can be used. For example, FTP/ssh/Telnet/print/Web Services. There are a total of 65536 ports in the computer system, so connecting to these ports and scanning out available ports makes sense.1. Network Connection
The network of Kali is not hosted by the device by default, so you need to enable it. Enabling method:

There are now port-proof tools, such as Psad, Portsentry, but feel the configuration is a bit cumbersome, and the server does not want to install an additional software. So I wrote a shell script to implement this function. The basic idea is: the use of iptables recent module records in 60 Seconds to scan over 10 ports of IP, and combined with the Inotify-tools tool
Nmap is a tool for network exploration or security evaluation. It supports ping scanning (determining which hosts are running), multi-port scanning technology (determining which services are provided by hosts), and TCP/IP fingerprint (remote host operating system identification ). Nmap also provides flexible target and port list, cover scanning, determination of
