I have a vps server that is blocking me every hour via ip with its firewall. Looking the logs several messages like these where found:
Dec 16 13:52:08 srv kernel: [17226167.610181] Firewall: UDP_IN Blocked IN=venet0 OUT= MAC= SRC=22.214.171.124 LEN=60 TOS=0x00 PREC=0x00 TTL=1 ID=494 PROTO=UDP SPT=59052 DPT=33479 LEN=40
Looks like this indicates attempted contact on ports from 33479 to 33511 from my local pc without my feelingly. This rage of ports are not allowed to connect from remote connections. That is why the firewall block me.
I am running Fedora 20. I have thought that maybe a virus (not sure if fedora can catch virus) is trying to connect to my server using a malicious program. So, is there a way to look what program/script is trying to connect remotely to the server using that ports?
