ODP libpcap example
This document explains how to test the libpcap which integrate the ODP.
(a) Compiling the libpcap
Must have ODP libs before compiling this example. Make sure those files exist:
- <odp_root>/build/include/
- <odp_root>/build/lib/libodp.a
build libpcap at <odp_root>/test/libpcap/:
$> make
or add ODP_HAVE_NETMAP=yes to enable the netmap support:
$> make ODP_HAVE_NETMAP=yes
install to system:
$> sudo make install
(b) Testing
test it through tcpdump:
$> sudo ./tcpdump -ni odp:eth0
test it through wireshark:
$> sudo ./wireshark -i odp:eth0
test the tcpdump bridge:
$> sudo ./tcpdump -ni b:eth0,eth1
test it through tcpdump with netmap pktio:
$> sudo ./tcpdump -ni netmap:eth0
test the tcpdump bridge with netmap pktio:
$> sudo ./tcpdump -ni netmapb:eth0,eth1
(c) Note
1. Currenly system default tcpdump can't successfully do mlock which is needed
in ODP. So this example will use self-build tcpdump instead.
2. Same reason as tcpdump, you can use self-build wireshark if you got mlock
related error.
$> sudo apt-get install autoconf bison flex libtool libgtk2.0-dev libpcap-dev
libc-ares-dev libsmi2-dev libgnutls-dev libgcrypt11-dev libkrb5-dev
libcap2-bin libgeoip-dev libortp-dev libportaudio-dev wireshark-dev
$> make wireshark
