Hello everyone,
I am trying to get Tcpreplay to work with FreeBSD 7.2. I've successfully
installed the tool but when I attempt to run this command:
$ tcpreplay -l 1 -p 2500 -i nfe0 -I nfe1 -c cache.prep my_dataset.pcap
I get the following error:
"Fatal Error: Invalid interface name/alias: nfe0"
If I do a ifconfig, the following information is shown:
nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:1e:8c:b1:de:91
inet 192.168.1.111 netmask 0xffffff00 broadcast 192.168.1.255
media: Ethernet autoselect (100baseTX <full-duplex,flag0,flag1>)
status: active
nfe1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:1e:8c:b1:e3:4f
inet 192.168.1.112 netmask 0xffffff00 broadcast 192.168.1.255
media: Ethernet autoselect (100baseTX <full-duplex,flag0,flag1>)
status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
inet6 ::1 prefixlen 128
inet 127.0.0.1 netmask 0xff000000
As far as I can tell, the aliases for my two network interface cards are
correct, so why is Tcpreplay not recognising them? Furthermore, I've used
the exact same command on a Linux distro (ubuntu) and it works perfectly
fine there (as long as I replace nfe0 and nfe1 with the aliases eth0 and
eth1 which is given in the Linux distro). Can anyone tell me what I might
be doing wrong?
Thanks.
Owen.
