Have to ask - why servers preinstalled and default configured?

 

I found NFS/rpcbind and OpenVPN preinstalled on the image - this is a security risk that can be easily avoided.

Idea was to provide client part, so I don't know why server was also there.

Thanks.

 

 

Sorry for bumping, but I have just tried Armbian_23.02.2_Pine64_jammy_current_5.15.93.img and there is rpcbind started on boot and listening on all interfaces:

I think this is a security risk

Seems like nfs-common depends on rpc-bind which is the reason this is pre-installed. So multiple ways to address:

 

- leave it as it is

- remove nfs-common and therefore rpc-bind

- provide custom config to make rpc-bind listen to localhost only (which could confuse users who'd expect default behavior instead on installation)
