Hi there, attempting to use Wireshark to debug a faulty app, I am struggling to use rvictl to create a virtual interface.

Macbook Air 2015 running Big Sur 11.2.3
iPhone 6 running iOS 12.5.2
Xcode 12.4 installed
Manually installed mobiledevice.pkg and mobiledevciedevelopment.pkg packages in

Code Block  Applications/Xcode-beta.app/Contents/Resources/Packages

issued command

Code Block sudo launchctl load -w /Library/Apple/System/Library/LaunchDaemons/com.apple.rpmuxd.plist

which throws

Code Block "Load failed: 37: Operation already in progress"

When issuing the command (with or without sudo):

Code Block rvictl -s <phone-UID>

It throws:

Code Block Starting device <phone-UID> [FAILED]

I have executed

Code Block sudo installer -pkg /Applications/Xcode.app/Contents/Resources/Packages/MobileDeviceDevelopment.pkg -target /

which returns:

Code Block installer: Package name is MobileDeviceDevelopment
installer: Upgrading at base path /
installer: The upgrade was successful.

Any idea?

Any idea?

Regarding the rvictl side, this should be captured in a bug report.
Although not from the exact versions you mentioned, I was able to get rvictl to enable rvi0 on iOS 12.4.4 from Big Sur 11.2.

Code Block text$ rvictl -s e...2
Starting device e...2 [SUCCEEDED] with interface rvi0
$ tcpdump -D

Hello and thanks for your reply.

Could the message

Code Block "Load failed: 37: Operation already in progress"

which appears when entering the following command

Code Block sudo launchctl load -w /Library/Apple/System/Library/LaunchDaemons/com.apple.rpmuxd.plist

mean that something has not yet loaded correctly?

No. Consider this:

Code Block  % sudo launchctl list | grep com.apple.rpmuxd
-	0	com.apple.rpmuxd

So, the job is loaded on my Mac. Now this:

Code Block  % sudo launchctl load -w /Library/Apple/System/Library/LaunchDaemons/com.apple.rpmuxd.plist
/Library/Apple/System/Library/LaunchDaemons/com.apple.rpmuxd.plist: service already loaded
Load failed: 37: Operation already in progress

Error 37 is EALREADY which just means that the job is already loaded.
