Is such type of question acceptable here? Idk, I am looking for anything like requests from LAN through my computer's vpn to anything unusual like torrent clients, games sites/servers various video sites (except youtube). And so on. Maybe a hidden VPN traffic inside my vpn. Anything like remote desktops.
Depends on the question. In general, I would say:
- "Here's a traffic dump. Notice anything strange?" Will be closed as "needs focus".
- "Here's some relevant subset of trafic. I suspect X. Is that correct?" Probably OK question!
- "Here's some small subset of trafic that I don't understand. I expected X but got Y. What is going on here?" Probably OK as long as there is a security angle to it.
The key is that you need to focus on something specific, and not just a big dump of traffic. The goal is for questions here to be useful for more than just the person asking them. Since your traffic is unique to you nobody else will benefit from a general analysis.
If your goal is "to find any backdoor/rootkit by using wireshark without knowing anything" it is not specific enough to ask here, I'm afraid.
