Use line mode to display (the specific data of the package will not be seen in this mode) I normally use iptrace on our AIX servers to get packet traces but have recently found out that this doesnt work for other nix systems - namely Centos.

Commonly used Unix system packet capture methods HP-UXДЇormat: nettl -traceon -entity -n num_files -tracemax tracefile_size*2 -file tracefile_path If the network card is working in the 'normal mode', only the IP packets sent to the machine will be received by the kernel and sent to the application. In order for the packet capture program to capture all network packets flowing through the network card, the network card needs to be set to 'promiscuous mode', so that all network packets are sent to the packet capture program for analysis. An important way to solve this problem is to capture packets on the host. Run iptrace on AIX interface en1 to capture port 80 traffic to file trace.out from a single client IP to a server IP: iptrace -a -i en1 -s clientip -b -d serverip -p 80 trace.out This trace will capture both directions of the port 80 traffic on interface en1 between the clientip and serverip and sends this to the raw file of trace.out. If the packet can be captured, but the application data is still not there, there may be a problem with the application parsing, or it may be blocked by the host's own firewall otherwise, the packet may be dropped somewhere on the network. In the process of network fault diagnosis, it is often necessary to determine whether the network packet sent by the other party reaches the host, and then to understand whether the problem lies at the network level or the host application level.
