Security Alert - Suspicious Connections Detected on My Server

[meryem]

Hello ,
My public IP address is zho connect with ssh. While analyzing active connections using the ss -tnp command, I noticed several foreign IP addresses connected to my server on port 111 (rpcbind), as shown below:

183.129.159.242:28932
115.233.218.204:32133

These IP addresses do not belong to me, and I am concerned they might represent malicious connection attempts , this ips address is normal to be in serveur ?

You simply should not have PVE exposed to the internet and if you really have to, please, use a firewall. PVE has a nice on integrated in the GUI that will help you protect your server.
