[jpfleischer]

implementation without ips is done as. implemented in cloudmesh inventory

cms host find

cms host find [--ips=IPS]
ips = Parameter.expand(arguments.ips)
for ip in ips:
    try:
      r = Shell.run(f"ssh {ip} hostname -I").strip()
      # we find the hostname, maybe with try except
      if error:
          report
    except Exception as e:
        print(e)
        Console.error("failed")

how do we use this?
cms host names --ips=192.168.1.[100-103]
add "How to use" this into the FAQ
e.g. "what if my hostnames dont show up in my network?"

perhaps use nmap... it must be installed first.

[laszewsk]

there were lots of confusion about this. Former student die not think it works, however i think other then documentation this works and was implemented.
