Listing all active internet connections on Linux
By jeltsch on Wed, 09/02/2020 - 07:31There are many possibilities, but perhaps the most friendly command is:
netstat -natp
The fact that everything looks different doesn't mean that all has changed...

PXE-booting from Netgate Pfsense SG-3100

To install Linux without the need of a CD/DVD/USB-stick, I now use PXE-booting ("pixie"-booting) on our local home network.

Scanning my home network (nmap)
By jeltsch on Sun, 03/18/2018 - 16:00Scanning my home network for all devices that are listening
on port 80 (http):
nmap -p80 192.168.0.0/24 -oG - | grep 80/open
Sometimes this doesn't work (because nmap tries to be smart and only scan hosts that are available). In order to make nmap scanning without intelligence, use the e-Pn (no ping) option. This scans all ports of host 192.168.0.2:
nmap -Pn -p0-65535 192.168.0.2
