Why does my pc make so many connections? (lemmy.ml)

Hello all,

According to the Wireshark record my computer connects to various services often, including Amazon, Hetzner, 1337 Services GmbH, Evanzo GmbH and ThomasFamilyInvestments. The most often were the connections to mail.my-mail.rocks which is a part of Netcup GmbH. I have a somewhat minimal distro and the attached recordings were made when no app was open including no browser. I can send the other screenshots showing other connections too. I'm suspecting of malware since some time ago but can you help me clarify these connections please?

I find wireshark too confusing unless you have a lot of experience with it.

It looks like you are using linux because I see Wlan0 at the top of the image

I use ss

ss --help

to see what you are connecting to

ss -x -a

ss -o state established

ss -o state established '( dport = :http or sport = :http )'

what processes are using open sockets

ss -pl

TCP sockets

ss -t -a

UDP sockets

ss -t -a
