Hello,
I'm running Backtrack 5 on in an VM (VMware Workstation) and I am getting troubles when I try to do a arpspoof on our LAN Network (not an other VM).
I used the tutorial of Hak5:
Doing this I'm getting this error:
arpspoof: couldn't arp for host 192.168.123.254[/CODE] The LAN Computer's Network Address is: 192.168.123.102 Im doing to following things for ARP Spoofing: [CODE] cat /proc/sys/net/ipv4/ip_forward echo 1 > /proc/sys/net/ipv4/ip_forward cat /proc/sys/net/ipv4/ip_forward screen arpspoof -t 192.168.42.254 192.168.123.102 CTRL+a S (Split) CTRL+a TAB (Jumping to next display region) CTRL+a C (Create the session in region) arpspoof -t 192.168.42.102 192.168.123.254 [/CODE] The first one giving me an result, but the second one (arpspoof -t 192.168.123.102 192.168.42.254) gives the error I gave above. My ifconfig looks like this: [CODE]eth1 Link encap:Ethernet HWaddr 00:0c:29:27:8d:30 inet addr:192.168.42.135 Bcast:192.168.42.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe27:8d30/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1446 errors:0 dropped:0 overruns:0 frame:0 TX packets:2823 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:89969 (89.9 KB) TX bytes:148952 (148.9 KB) Interrupt:19 Base address:0x2024 [/CODE] Instead of 192.168.42.254 I also tried using 192.168.123.254 (which is the one on the PC running the VM) which is also not working. If anyone could help me, I would really apriciate that :) If any more information is needed, tell me :) Regards, Melvin Koopmans
