                          Scanning the machine on the LAN with my laptop, I got this:

    gabriele @ osiris { ~ } [ Tue Oct 07 ] [ 08:49 PM]
     nmap -sP 192.168.1.236
    
    Starting Nmap 6.40 ( http://nmap.org  ) at 2014-10-07 20:50 CEST
    Nmap scan report for ---.homenet.telecomitalia.it (192.168.1.236)
    Host is up (0.0044s latency).
    Nmap done: 1 IP address (1 host up) scanned in 0.03 seconds

nmap won't recognize the nostname, putting—in place of "mercury" and I assume is not a problem of nmap because it doesn't even access in this way:

    root@mercury

when I changed the hostname I follow these steps

    sudo nano /etc/hostname

and I wrote a single line with "mercury", then:

    sudo nano /etc/hosts

with this configuration:

    127.0.0.1       localhost
    127.0.1.1       mercury localhost
    ::1             localhost ip6-localhost ip6-loopback
    fe00::0         ip6-localnet
    ff00::0         ip6-mcastprefix
    ff02::1         ip6-allnodes
    ff02::2         ip6-allrouters

and finally:

    sudo /etc/init.d/hostname.sh start

am I doing something wrong?
