How to capture packets bound from/to solely one application?
#### My Rationale I want to diagnose [`github.com/AchetaGames/Epic-Asset-Manager/issues/318#issuecomment-3641224648`](https://github.com/AchetaGames/Epic-Asset-Manager/issues/318#issuecomment-3641224648) — a failure to access a (likely non-existent) API endpoint. [^5] On AOSP, I would invoke PCAPDroid, and select the relevant application (from a list, enumerated from `getPackageManager.getInstalledApplications`). [^2] [^3] However, that's unavailable here, and `wireshark-4.6.0-1.fc43` doesn't make achieving this task a trivial endeavour [^4] (albeit, likely because of how powerful it is, and how much less restricted *and* standardised desktop OSes' APIs are.) [^6] Does a way to monitor the network traffic of a single application exist? I see [`powerusers.codidact.com/posts/283650/history#2`](https://powerusers.codidact.com/posts/283650/history#2), although am not certain whether it's applicable here, because this isn't a DNS failure, and most alternative sources suggest a port, [^8] or VLAN, [^7] –based approach: [^8]: [`superuser.com/questions/1370924/how-can-i-monitor-all-activity-from-only-one-software-with-wireshark/1371095#comment3018542_1371109`](https://superuser.com/questions/1370924/how-can-i-monitor-all-activity-from-only-one-software-with-wireshark/1371095#comment3018542_1371109) [^7]: [`superuser.com/questions/1370924/how-can-i-monitor-all-activity-from-only-one-software-with-wireshark/1371095#comment3018544_1370924`](https://superuser.com/questions/1370924/how-can-i-monitor-all-activity-from-only-one-software-with-wireshark/1371095#comment3018544_1370924:~:text=If%20you%20don't%20you%20could%20create%20a%20(virtual)%20network%20interface%20and%20let%20only%20one%20application%20use%20it) > You could create a (virtual) network interface, and let only one application use it.
