Hello everyone, Someone can help me, I have a problem to run "arpspoof", when I run the command: #arpspoof -i eth0 -t myLocalAddress gateway, it returns this error "arpspoof couldn't arp for host". I'm executing from a VM. Let me know the solution. Thank! Maybe u did any wrong with the commands? what kind of virtualization app are you using? @Panoshoopaz My friend, the commands are right, I think that is not the problem. @SpiderX I'm using the VirtualBox. This problem occur only when I run the command with my IP Address as target. Example: **\#echo 1> /proc/sys/net/ipv4/ip\_forward - this command was successful****\#arpspoof -i eth0 -t destinationAddress localAddress - this command was successful*****\#arpspoof -i eth0 -t localAddress dsestinationAddress - this command returns the message “arpspoof couldn’t arp for host”*** My network was configured in bridge mode. My ip address is and ip address of the target is Any idea about this problem? Felipe:) if the commands is right, hmm u can check the options on vm about permissions @Panoshoopaz please let me know what permissions? if the arpspoof can't translate hostname to ip address , you should add in the /etc/hosts of your backtrack (or kali) the ip address and the hostname of your local machine as well the remote (target machine), or you may need a dns to resolve hostname to ip address. and make sure your network is set to bridge if the remote machine is a physical host. @Spider I'm access per IP, not by hostname. I have sure that my Virtual Machine was set as bridge. Do you have another idea about this problem? Thanks Have u seen about iptables bro? @panoshoopaz I tried it, but I can't verify iptables status. When I run "service iptables status" it returns "iptables unrecognized service". Do you have another idea? Ok firtst,what operate system do you have,to see if this is a problem? second i think u only can run arpspoof in the same gateway,not in different bro :) The system it's windows 8.1, I tried run arpspoof in another gateway and some differents computers, but unsuccessful... Hi, I would try to use ettercap instead of arpspoof. Here the steps to take for doing arpspoofing even over SSL connection: echo "1" > /proc/sys/net/ipv4/ip\_forward iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 8080 sslstrip -l 8080 ettercap -TqM arp:remote // // Your log file is in: sslstrip.log tips: Sometimes the ip\_forward is reset by the OS so creating a script to run echo "1" > /proc/sys/net/ipv4/ip\_forward in a loop as long as you are doing spoofing should keep you hitting forward issues. :)K Try SSLStrip+ which is the sslstrip v2 :). Thanks Ketil, I will try it... Try NAT instead of bridge connection. I have tried... but don't worked... :/ What does ifconfig show? I do remember having to set the network settings in a certain way when I wanted to connect to a webserver on one VirtualBox VM from another VirtualBox VM on the same Windows 7 host. I would start on the VirtualBox forums. First make sure you can ping your target ( from your host ( and the other way too - though I have never experienced a one way ping though I suppose a firewall between to systems could be set up to do that. @Panoshoopaz in your opinion is a permission error? Hello, Sorry for reply so late... My ip configuration is ok... I think this is some problem in VirtualBox... I'll try to run within Kali Linux as main OS... Use Bettercap. On my home network I had problems with arpspoof, using bettercap I solved them. Install bettercap and run: bettercap -I \[interface\] -T \[target\] @TheFedex87 I'll try and let you know about the results... Thank you Im having the same issue. I'm using nat in vmware and my router is my target pc is i can ping both of them but can't do arpspoof im using these commands "echo 1 > /proc/sys/net/ipv4/ip\_forward" "sysctl net.ipv4.ip\_forward" To spoof: "arpspoof -i eth0 -t" "arpspoof -i eth0 -t" im connected through eth0 interface and can access net i tried bridged connection but didn,t work for me.... kindly help.. @Felipe Oliveira check that whether your default gateway( your roter address) and your victim default gateway is same.... use "route" to check in kali and ipconfig in win ..... i had the same issue i changed my kali gateway to victim pc gateway and then atlast i can do arpspoofing.... I hope it helps... Im having the same issue.did u solve it. if so,help me pls.....
