when I use nslookup my IP address, it respond my hostname that 53.50.168.192.in-addr.arpa name = e1db6296bb57494.

Now I want to use nslookup with my hostname. Example: #nslookup quartslove. And others can khow me as quartslove, not my IP address. I've used hostname to change my hostname, and I also change in /etc/host, but there's nothing change.

First, nslookup is a horrible tool to query DNS servers. If you want to know what is actually going on, you have to use dig.

2nd, you can't control what name your nameserver gives for your computer from your computer. The nameserver needs to know your name to reply with it. You would need to create a forward and reverse lookup for quartslove, and most home routers don't allow you to do that. You would have to be running a proper nameserver, not just the caching server build into home networking devices.

3rd, why? The only people who can find your computer on the private 192.168.50.0 subnet are those on your LAN. Just give yourself a static mapped IP address, and let them connect to you that way.

They can connect to me, but not my hostname also. Is there any trouble with my computer and my network files ?
Thanks all .

There we go, it isn't a DNS issue, it is Samba. Samba is the service used to share files with the windows world. Your name under samba is usually your hostname, which can be configured as root. Use "man hostname" for more details on setting your computer's name.
