It looks to me like we have the following items
UDP
IPv4
Open ports sunrpc, 32771
Question 1: What is *.* Unbound?
TCP
IPv4
Open ports sunrpc, ssh
10 ports open only for localhost
The open ssh connection from my PC
Question 2: What is *.32785 *.* 0 0 49152 0 BOUND?
Question 3: What is *.* *.* 0 0 49152 0 IDLE? (shows up twice)
IPv6
Open port ssh
Question 3: What is *.* *.* 0 0 49152 0 IDLE?
Question 4: What is SCTP?
Question 5: What is Active UNIX domain sockets
