I am trying to ping device on my network by device name, it works on my Linux computer and does not work on my NPi R1.
Expecting pinging the device name will retrieve ping data including my device local IP.

 

$ ping HPC0180319938E.local
ping: HPC0180319938E.local: Name or service not known

I preformed

sudo apt update && sudo apt upgrade

 

 

Not sure how to check ping command version.

Welcome to Armbian 22.08.8 Focal with Linux 5.15.74-sunxi

 

Most likely userspace issue.

Is avahi daemon running?

Looks like I've found a solution.  See: https://askubuntu.com/questions/772774/unknown-host-even-though-avahi-is-installed-and-running

 

I installed libnss-mdns and altered the hosts: line in /etc/nsswitch.conf to read:

hosts:          files mymachines mdns4 [NOTFOUND=return] dns myhostname

 

resolving mdns names is now working for me.

It looks like even though avahi daemon was running I was missing

libnss-mdns

 

so just installing it using

 

sudo apt install libnss-mdns

 

solved it.

 

In my case /etc/nsswitch.conf already had similar content, maybe from my previous attempts to solve this

 

hosts: files mymachines mdns4_minimal [NOTFOUND=return] dns myhostname

 

Thanks for all the help
