Ethernet packet sending tool (xcap)The official version is a tool that can read all network interfaces from the system. The xcap packet sending tool can send constructed packets from the specified interface and supports two simple sending strategies. One is to send the selected one (selected with the mouse), and the other is to send the reply in a loop. The Ethernet packet sending tool (xcap) also supports the construction of common Ethernet packets , including arp, rarp, ipv4, ipv6, icmpv4, icmpv6, etc. Huajun Software Park provides you with a free download of the Ethernet packet sending tool (xcap) 2024. Friends who like the Ethernet packet sending tool (xcap) come to Huajun Software Park to download and experience it!
Ethernet packet sending tool (xcap) software functions
1. Construct the message
Supports the construction of common Ethernet packets, including arp, rarp, ipv4, ipv6, icmpv4, icmpv6, igmp, udp, tcp, pim, ospf, rip, snmp, ppp, pppoe, ipsec (ah/esp), etc., as well as some uncommon packets, such as 802.3, STP, etc. Some of the agreements were not completed.
Use the wizard to construct the message, and construct the header of each layer of protocol in turn; after constructing the header of a layer of protocol, select the corresponding next header type from the interface, and then click Next to generate the corresponding protocol. For example, select 0x0800 for Ethernet, click the Next button to create the IP header construction interface.
2. Send message
WinPcap can read all network interfaces from the system. This function can send constructed messages from the specified interface. It supports two simple sending strategies, one is to send the selected ones (selected with the mouse), and the other is to send the messages selected in the check box in a loop.
3. IP fragmentation
4. Respond to ARP/NDP query
5. Respond to ICMP Echo Request
6. TCL control transmission
7. Support Chinese and English interfaces
8. Provide file browsing in WinPcap format, which can be used in conjunction with WireShark
9. Packet capture and message analysis
Ethernet packet sending tool (xcap) software features
1. The maximum supported message length is 64K. There is no length check in the software. Exceeding this length may cause the software to exit abnormally;
2. The packet capture function does not limit memory usage. If the number of captured packets is too large, the software will exit abnormally. The packet capture function is only for simple testing and TCL script use. For large amounts of data or complex functions, it is recommended to use dedicated packet capture software, such as Wireshark, etc.;
3. Supports a maximum of 16 network interfaces;
4. Each message group supports a maximum of 32768 messages, and the software does not check;
5. The traffic test is not accurate, which is determined by the operating system. This software focuses on the construction and sending of messages. Due to the influence of the operating system and WinPcapSDK, it can only do simple traffic tests;
6. Different versions of message files (.
How to use the Ethernet packet sending tool (xcap)
1. Construct an IPv4 message, select "0x32 (ESP)" for Protocol
2. Fill in the ESP data part:
3. Right-click on the created message, click "View Message" in the pop-up menu to display the wireshark window. Since the message is encrypted, it cannot be displayed. You need to configure the key in wireshark. The configuration process is as follows. Right-click on the ESP part in wireshark and open "ESP" in the pop-up menu. SAs"
In the pop-up dialog box, click "New" to create a new rule and enter the following:
The source address and destination address are addresses in IPv4. The type and key of SPI and encryption authentication are in the ESP protocol. Click OK to return to the main interface of wireshark. You can see that the message has been decrypted:
