Why don't you use static IP address for your NAS?

I wonder if the OP is even using Debian, ? " Linux" could be any of the 100s

If you are looking to scan your local network with GNU/Linux to find your NAS ip, try nmap. (For Windows I use angry ip scanner)

For example:

Code: Select all

russel@NUC-G:~$ nmap 192.168.2.0/24

Starting Nmap 7.40 ( https://nmap.org ) at 2017-11-20 14:17 PST
Nmap scan report for 192.168.2.xxx
Host is up (0.015s latency).
Not shown: 999 closed ports
PORT   STATE SERVICE
80/tcp open  http

Nmap scan report for 192.168.2.xxx
Host is up (0.000049s latency).
Not shown: 999 closed ports
PORT   STATE SERVICE
22/tcp open  ssh

Nmap done: 256 IP addresses (2 hosts up) scanned in 4.08 seconds
(Clearly, I have 'xxx'ed out the last three digits of the IP adresses)

What does "don't work" mean?

# man ifconfig and # ip r don't work.
'man ifconfig' should get the manual, it is standard on any linux system.
It does not need to be run as root either. Where did you get the idea to run it as root " # " ?

Nor me,:

Code: Select all

man ifconfig
said to run these commands as root,

But maybe the OP should also include the out put of:

Code: Select all

uname -a
So we can see what version of Debian, or which
"Linux" is really being used here.

I hope you know that 192.168.x.y belong to the private IPv4 space so you can post whatever addresses you may have.
They are not routable/reachable from the outside (regardless of NAT or any port mappings you may have).

Yes, I am aware of that. It just goes to show how paranoid I am! I don't even want to advertise my lan ip address

I don t want to use the nas wen my computer is connected to the internet that's why i say 'local network'
at this time i use kali because i can't install nmap on debian with ease.

Yes, but this is Debian, not windows, or is it Kali,? .... what OS are you really
using ?

The OP needs to look at the specifics for "kali", especially on configureing the net works. Kali is not Debian, but that does explain why :
root@kali:~# man ifconfig
root@kali:~# man ifconfing -v
Apparently it is not just Kali, but also the newer Debian versions, in fact they blame Debian, but any way, you need to install : "net-tools"
https://forums.kali.org/showthread.php? ... t-found!!!
sudo apt install net-tools
should solve the problem,
This would be better to ask about on the kali forums.

^^ This, ladies and germs, is BS. Windows or Kali, networking standards are the same and this is not a valid private IP address, nor is it a valid public address. It is an IP address assigned by DHCP client when network is screwed up (local link address). IMHO this is another wannabe hacker who has no business running Kali, these are networking basics we are talking here.

Kali is not Debian, it is a distro for professional pen testing on a live medium. For assistance with Kali please use the Kali forums.
