I’m configuring a Debian (Stretch) webserver to run docker containers for socks requests.

I am looking to set up self-hosted cloud storage, and need to open a port in order to do this.
This would be hosted on a raspberry pi with an external drive that I used to store my important documents.
The raspberry pi uses NordVPN w/ open… Continue reading Openvpn blocks external traffic [migrated]
If we have a private network connected to the Internet with NAT, how can an attacker estimate the number of host computers in network using port scanning?
For both possible modes, the attacker inside and outside the private network.

I want to install and run scanlogd from my Ubuntu 16.04 machine. I am able to install and run it with apt-get install scanlogd and it works fine.
But I am not able to change the parameters like log count threshold or max length of a messag… Continue reading How to install and use scanlogd

My context: I’m looking into running a rootless Dock… Continue reading Security implications of granting non-root access to privileged ports (<1024)
I have a single home server with a single NIC. I intend to run numerous services — some will be internet exposed, some will not. I don’t know if I am going to run them as VMs or Docker container but it shouldn’t matter for this question.
… Continue reading What is the threat/risk difference in opening multiple ports on one physical NIC on a home server vs creating VLANs and opening ports on each VLAN?
Listing all the ports currently in use on my mac running $ sudo lsof -i -n -P | grep TCP, I see six entries starting with a weird-looking string of "2BUA8C4S2".
A web search for that string yields some results, but no explanation… Continue reading What’s this port? [closed]

I’m currently learning about network security and came across a problem, maybe I’m just missing something obvious but I’ll try to explain my environment:
I have a Kali Linux VM connected to the WAN Interface (192.168.178.109) of a Pfsense … Continue reading scan forwarded ports with OpenVAS/GVM?
