Request: separate arp.spoof and arp.ban into individual modules #874

Closed lecatos closed 3 years ago

lecatos commented 3 years ago

Description of the bug or feature request The description and the title is straight forward. When I do "ARP.BAN OFF", IT ALSO TURN OFF ARP.SPOOF idk if this is a bug or they intended to do this but if they intended to do this, I don't want this to happen because I wanted the spoofing to continue to work after I turned off ban mode. I know that I can just do "arp.spoof on" back but I am not fast enough because in my case, the victim device will try to make a http request when it is disconnected (this disconnection is caused by me doing "arp.ban on") and when the victim tries to make a http request, I should do "arp.ban off" to spoof their http request but instead when doing "arp.ban off" it also turn off arp spoofing (arp.spoof) therefore my http spoofing will fail.

In order for my attack to be successful, I will have to manual set "ip_forward" file to 1 which is equivalent to doing "arp.ban off" except this manual way, arp.spoof won't be stopped automatically thus making http spoofing in "my case" possible.

Environment

Please provide:

Expected behavior: What you expected to happen What I expected to happen is that after I run "arp.ban off", it should only turn off ban mode and not the entire arp spoofing Actual behavior: What actually happened it turned off arp spoofing --

♥ ANY INCOMPLETE REPORT WILL BE CLOSED RIGHT AWAY ♥

You can execute multiple commands using a semicolon separator (arp.ban off; arp.spoof on) but in your case, stopping the arp.ban module will begin to restore the ARP cache of those victims, possibly causing some packet loss.

I'll mark this as a suggestion.

i could add an option to skip arp cache restoring when turning arp.ban and/or arp.spoof off so you could do what @buffermet here suggested and it'll be quick enough
