I am doing a wireless experiment which used a tp-link router WR1043ND flashed OpenWrt system. Because I need to catch packages through the router, I need to install the tcpdump software.
I just used the command "opkg install tcpdump" to install it, and the terminal showed installation successful.
But when I entered "tcpdump" command, I got a failure prompt which showed that
-ash: tcpdump: not found
So I try to know whether the tcpdump was installed. I entered as following:
opkg list | grep tcpdump
the result after filter showing:
openvswitch-ovs-tcpdump - 2.8.1-1 - Dump traffic from an Open vSwitch port using tcpdump
openvswitch-ovs-tcpundump - 2.8.1-1 - Convert ``tcpdump -xx`` output to hex strings
pcapsipdump - 0.2-1 - pcapsipdump is a tool for dumping SIP sessions (+RTP traffic, if available) to disk in a fashion similar to "tcpdump -w" (format is exactly the same), but one file per sip session (even if there is thousands of concurrect SIP sessions).
tcpdump - 4.9.2-1 - Network monitoring and data acquisition tool
tcpdump-mini - 4.9.2-1 - Network monitoring and data acquisition tool (minimal version)
tcpreplay - 4.2.5-1 - tcpreplay is a tool for replaying network traffic from files saved with tcpdump or other tools which write pcap(3) files.
Obviously, the installation was successful. I really hope somebody can help me handle this question, thanks!
