Knowlegebase HPE Linux KB0013 - Creating .pcap Files with tcpdump It’s often more helpful to capture packets using  tcpdump rather than wireshark , as it is available as a package in most Linux and BSD package managers. For example, you might want to do a remote capture and either don’t have GUI access or don’t have Wireshark installed on the remote machine. Older versions of tcpdump truncate packets to 68 or 96 bytes. If this is the case, use -s to capture full-sized packets:  $ tcpdump -i -s 65535 -w You will have to specify the correct interface and file name to save into. In addition, you will have to terminate the capture with Ctrl+C when you believe you have captured enough packets.   Authentication LDAP Response Codes Below are the codes that an LDAP query can return.
