TODO

• <todo: review ns-3, as candidate first project, >
• <todo: focus on use to combat global waring and climate change, extreme weather attribution (Imperial), linking models of different kinds, >
• <todo: relation to ai, >
• <todo: relation to robotics, iiot, remote sensing, telemetry, >
• <todo: relation to neuromorphic computing, as interneuron interbrain substrait?, parallel multi gai processing, multi agent processing, >
• <todo: relation to music, sonics, consider a music repository, pitch encoding and transmission, ! >
• <todo: consider, project re DNS DHCP on local host Ubuntu 24.04 or Ubuntu 26.04, using; pi-hole, dnsmasq, others tbd, objective to block predatory internet domains, >
• <todo: consider, curl file transfer, to remote address, >
• <todo: consider, curl project, how can it be used in relation to AGW project in general, specifivally curl to Raspberry Pi SBC's and other embedded system, >
• <todo: consider, vnc for remote access, RPi Trixie in first instance on RPi Zero, is vnc access possible with Ubunut Core tbd? in which use cases would vnc beneficial for AGW project? in which use cases would vnc be prefereable to ssh? >
• <todo: consider, AGW organisation 'enterprise' network use cases, many, see ssh project for some identified, to identify others, >
• <todo: consider, AGW org h2h communications concerns, many, find GDPR compliant instances, explore Jitsi as candidate solutions or building blocks, /tsi? sub project, prioritise FOSS, LFP options, attempt convergence with Cannonical/Ubutntu/Debian in first instance, look also at RPi re same, others tbc? >
• <todo: consider, AGW org m2m communications concerns, automation, system and software updates, others, stub >

DONE

• <done: consider, intent to commit>
• <done: consider, choose a project, ssh, first cut Ubuntu Core and One SSH, wip >
• <done: consider, ssh project, specifically in relation to AGW project and ssh to Raspberry Pi SBC's and other embedded system, headless access, priority for devsecops for AGW projects, wip>

Output

Localhost IP address - Linux

Get localhost ip address. All the ip addresses assigned to the machine network interface. Including primary ip address. Excluding loopback address.

$ hostname -I

Get localhost ip address. Just the first ip address assigned to the machine network interface

$ hostname -I | awk '{print $1}'

Get detailed ip address information

$ ip addr show
$ ip address show

Get ip address associated with the hostname.

$ hostname -i
127.0.1.1

Get IP4 addresses assigned to the machine network interface.

$ ip -4 addr show | grep -oP '(?<=inet\s)\d+(\.\d+){3}'
