Hi, I just got a bash bunny yesterday. I'm using macos, and initially I could connect via serial in arming mode (switch 3) and I could connect via ethernet (switch 1). I did an apt-get update/upgrade, ran into the problem with systemctl not knowing about procps, fixed that thanks to this forum, but after that, ethernet no longer worked (with the default switch 1 payload.txt: ATTACKMODE ECM_ETHERNET STORAGE). I've just looked at the doco again and noticed that it says (for macos) to use RNDIS_ETHERNET (not ECM_ETHERNET) which would mean that the default switch 2 payload.txt was the right one: ATTACKMODE RNDIS_ETHERNET STORAGE So that's confusing me. It looks like I did the wrong thing but it worked anyway (or maybe the doco is wrong?). Anyway, when I try switch 1, macos now reports that the RNDIS gadget has a self-assigned IP and when I try switch 2, it says that the RNDIS device is not connected. So that makes me think that ECM_ETHERNET is better on macos than RNDIS_ETHERNET. The self-assigned IP is because dhcp isn't working and I think the dhcp server isn't working because of a problem with usb0 but I can't seem to find the error message that mentioned usb0 anymore. Anyway, here's what I can find from arming mode (where I can still connect via serial): # systemctl --failed UNIT LOAD ACTIVE SUB DESCRIPTION isc-dhcp-server.service loaded failed failed LSB: DHCP server LOAD = Reflects whether the unit definition was properly loaded. ACTIVE = The high-level unit activation state, i.e. generalization of SUB. SUB = The low-level unit activation state, values depend on unit type. 1 loaded units listed. Pass --all to see loaded but inactive units, too. To show all installed unit files use 'systemctl list-unit-files'. # systemctl status isc-dhcp-server ● isc-dhcp-server.service - LSB: DHCP server Loaded: loaded (/etc/init.d/isc-dhcp-server) Active: failed (Result: exit-code) since Thu 1970-01-01 00:00:13 UTC; 1min 31s ago Process: 244 ExecStart=/etc/init.d/isc-dhcp-server start (code=exited, status=1/FAILURE) Jan 01 00:00:11 bunny dhcpd: Jan 01 00:00:11 bunny dhcpd: No subnet declaration for usb0 (no IPv4 a...).

Ah, but I can do systemctl start isc-dhcp-server and it succeeds, and from macos, it says the RNDIS gadget is "Connected" and has the right address, but it still doesn't work. apt-get update says: Err http://httpredir.debian.org jessie/main armhf Packages 504 Gateway Time-out W: Failed to fetch http://httpredir.debian.org/debian/dists/jessie/main/binary-armhf/Packages 504 Gateway Time-out Any idea what I've done wrong or what I can do to get ethernet working again? I tried rebooting and isc-dhcp-server failed again, starting it manually worked and everything looks ok but network connectivity still isn't working. This is wierd. From the macos host, I can ssh email@example.com and it works, but only after I've done a manual: systemctl start isc-dhcp-server from my serial port login. But from the bunny, I can't do: apt-get update So the networking is only working in one direction. Any idea what's going on? This is wierd. Thanks for any advice. cheers, raf Update: I have a lame solution for dhcp not starting up for me when ATTACKMODE has ECM_ETHERNET. It seems like maybe there's a bug in /root/ATTACKMODE but I can't see what it is. I don't know why isc-dhcp-server isn't running by the time that ATTACKMODE completes, but adding this to payload.txt after ATTACKMODE seems to fix it: systemctl status isc-dhcp-server || systemctl start isc-dhcp-server I still have the problem that apt-get update doesn't work anymore but it's got nothing to do with the bunny's networking. It is making a request to the squid proxy on the host server and squid is replying with: HTTP/1.0 504 Gateway time-out So it's a problem elsewhere (i.e. not bunny-related). cheers, raf
Hello there! Just got a bash bunny that worked fine when I got it. I decided to upgrade it using apt, and got a lot of issues. I fixed the problems I had with apt (fixed issues with procps), and now it seems to have some issues with DHCP when connecting to my computer using FNDIS_ETHERNET. If I connect the bunny and then set a static ip for it, I can ssh in as normal. Then I see that the service isc-dhcp-service has failed. If I try to start that service again, it seems like it works just fine. I get a dhcp lease from the computer and can GET TARGET_IP. So maby this is an issue with the usb0 interface not being ready when the dhcp server starts or something? I am not sure. It is pretty annoying that I have to set a static ip, log in with ssh, restart the service, set dynamic ip again just to get dhcp to work 😛 Have anyone else had any issues like this? I will provide you with more logs and stuff soon
