Fluxion: Device or resource busy after seconds

[marcusguita]

Do you want to request a feature or report a bug?

-> Bug

What is the current behavior?

-> Get error about interface down after seconds.

If the current behavior is a bug, please provide the steps to reproduce.

ifconfig wlan1 down
export FLUXIONDebug=1; ./fluxion.sh

selected wlan1 and search all channels. After seconds, get error "Device or resource busy"

After that, I run fluxion again, but select interface FXan1AP. Now its works.

What is the expected behavior?

->

If this is a feature request, what is motivation or use case for changing the behavior?

Install drivers properly and try it again.

https://github.com/FluxionNetwork/fluxion/wiki/Patch-driver

[marcusguita]

@deltaxflux I patched drivers but get same behavior... How can I check if drivers is it ok? I didnt get error on make and make install drivers. I rebooted after install. Thanks!

[MPX4132]

It seems like there's a process interfering with the interface, try this:

export FLUXIONDropNet=1; ./fluxion.sh

[marcusguita]

@MPX4132 I started with:

• ifconfig wlan1 down
• export FLUXIONDropNet=1; ./fluxion.sh

result after choice interface: "Unable to determine interface's physical device!"

[MPX4132]

Try running it with even more flags:

export FLUXIONAirmonNG=1; export FLUXIONDropNet=1; ./fluxion.sh

edit: I'm pretty sure your issue has to do with a process interfering, or the wireless card is failing. I use the exact same chipset for testing. That means yours should work perfectly fine as well.

[MPX4132]

By the way, why are you doing ifconfig wlan1 down at the beginning?

[marcusguita]

With command:

• export FLUXIONAirmonNG=1; export FLUXIONDropNet=1; ./fluxion.sh

I have same error ("Unable to determine interface's physical device!")

Without "ifconfig wlan1 down" I can't choice interface... I have a loop:

[MPX4132]

There's your problem. They're both purple because another process is using them. You need to stop whatever's using them. Bringing the interfaces down with ifconfig wlan1 down won't fix that problem. You found a bug, though, so I'll mark it as a bug.

[MPX4132]

You shouldn't have the first two interfaces:

phy1 FXan1AP ath9k_htc Atheros Communications, Inc. AR9271 802.11n
phy1 FXan1APAP ath9k_htc Atheros Communications, Inc. AR9271 802.11n
phy0 wlan0 iwlwifi Intel Corporation Centrino Wireless-N + WiMAX 6150 (rev 67)
phy1 wlan1 ath9k_htc Atheros Communications, Inc. AR9271 802.11n

Delete them with

iw dev FXan1AP del
iw dev FXan1APAP del

[marcusguita]

Interfaces FXan1AP shows after "fluxion scanner breaks" (first exec) and I start ./fluxion again...

I ran this commands (no interface found):

Check if the latest commit still gives you the "Unable to determine interface's physical device" error.

[MPX4132]

The "FXan1AP" thing is fine, I think fluxion already got rid of it.

[marcusguita]

Show this now:

Syntax error after open:

command not found (not show interfaces now)

[MPX4132]

Since you're having trouble with interfering processes, just keep running fluxion with:

FLUXIONDropNet=1; ./fluxion.sh

When you use that flag you can select the purple interfaces. When the flag is used, fluxion aggressively loads and unloads the interface, killing all processes that try to interfere.

[MPX4132]

I'm sorry, I left outdated code in the program. Let me fix it.

[MPX4132]

Go ahead and try the latest commit.

[marcusguita]

Now, "error on line" is red...

[MPX4132]

Ignore the Error on line message, it came up because you probably did export FLUXIONDebug=1; ./fluxion.sh and the killing services couldn't find avahi-daemon-ch.

Run the following and post the output:

Hmm that's pretty weird. It's all working fine...

[marcusguita]

I dont know if its help, but, in old fluxion (https://fluxion.tk/fluxion-stable.zip) works without problem this part...

[MPX4132]

Ok, I just ran a small test. It seems like there's two possibilities:

• Processes are still interfering somehow.
• Your wireless device is disconnecting.

Your device could be failing, making it unstable. If you're using a device that has a USB cord, the cord might be going bad. The USB port might be going bad, or the device's USB port might be going bad. The results you gave are consistent with random device disconnections.

This doesn't seem to be a problem with fluxion.

As a last effort, check that fluxion's interface library is working. Go into the fluxion directory (not the lib directory), and run:

source lib/InterfaceUtils.sh; interface_physical "wlan1"; echo "$InterfacePhysical"

That should give you something like "phy#" where '#' is a number. If it does in fact give you what I said, your issue isn't related to fluxion.

[MPX4132]

@marcusguita I just found an issue with FLUXIONDropNet, give me a couple of minutes to check it out.
edit: The problem is caused by FLUXIONDropNet not waiting for the interface to get ready. Give me a moment to see if I can come up with a decent solution.

[marcusguita]

about command: source lib/InterfaceUtils.sh; interface_physical "wlan1"; echo "$InterfacePhysical"

[MPX4132]

Try the latest commit, but run it with the FLUXIONDropNet flag:

export FLUXIONDropNet=1; ./fluxion.sh

[marcusguita]

Now stops here: "Waiting for interface "wlan1"..."

[MPX4132]

Try the latest commit with the new flag, FLUXIONDropNet was removed:

export FLUXIONWIKillProcesses=1; ./fluxion.sh

edit: If that doesn't work, restart your computer and try again.

[marcusguita]

@MPX4132 You are the best!!!! Its perfect now. Many thanks!!!

[MPX4132]

@marcusguita I wouldn't download the program from that site (https://fluxion.tk/fluxion-stable.zip). @deltaxflux do you know anything about it, is it safe for people to download things from that site? I don't think I've seen any mentions of that domain in this repository, leading me to believe it's a third party.

edit: The site is safe.

[MPX4132]

@marcusguita If you don't want to be typing export FLUXIONWIKillProcesses=1 every time, do this:
Make a file called preferences.sh on the fluxion directory, and add the following to it:

#!/bin/bash
export FLUXIONWIKillProcesses=1

Then make it executable with:

chmod u+x preferences.sh

Now you'll be able to just call fluxion normally: ./fluxion.sh

[deltaxflux]

@MPX4132 it is my site. I use it after I removed my fluxion.git earlier.

[MPX4132]

@deltaxflux Oh ok, I updated my comment.
