Ubuntu is a free computer operating system based on the Linux kernel. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

NAME

        hostname - show or set the system’s host name
        dnsdomainname - show the system’s DNS domain name
 

SYNOPSIS

        hostname  [-v] [-a] [--alias] [-d] [--domain] [-f] [--fqdn] [-i] [--ip-
        address] [--long] [-s] [--short] [-y] [--yp] [--nis]
 
        hostname [-v] [-F filename] [--file filename] [hostname]
 
        hostname [-v] [-h] [--help] [-V] [--version]
 
        dnsdomainname [-v]
 

DESCRIPTION

        Hostname is used to either set or display the current  host  or  domain
        name  of  the system.  This name is used by many of the networking pro‐
        grams to identify the machine. The domain name is also used by  NIS/YP.
 
    GET NAME
        When  called  without  any  arguments, the program displays the current
        names:
 
        hostname will print the name of the system as returned by the  gethost     
name(2) function.
 
        dnsdomainname  will  print the domain part of the FQDN (Fully Qualified
        Domain Name). The complete FQDN of the system is returned with hostname
        --fqdn.
 
    SET NAME
        When  called  with one argument or with the --file option, the commands
        set the host name or the NIS/YP domain name.
 
        Note, that only the super-user can change the names.
 
        It is not possible to set the FQDN or the DNS domain name with the dns     
        domainname command (see THE FQDN below).
 
        The   host   name   is   usually   set   once   at  system  startup  in
        /etc/rc.d/rc.inet1 or /etc/init.d/boot (normally by  reading  the  con‐
        tents of a file which contains the host name, e.g.  /etc/hostname).
 
    THE FQDN
        You  can’t  change the FQDN (as returned by hostname --fqdn) or the DNS
        domain name (as returned by dnsdomainname) with this command. The  FQDN
resolver(3) returns for the host
        name.
 
gethostbyname(2) returns for the host
gethostname(2).  The DNS domain name is the part after
        the first dot.
 
        Therefore it depends on the configuration (usually  in  /etc/host.conf)
        how  you can change it. Usually (if the hosts file is parsed before DNS
        or NIS) you can change it in /etc/hosts.
 

OPTIONS

        -a, --alias
               Display the alias name of the host (if used).
 
        -d, --domain
               Display the name of the  DNS  domain.   Don’t  use  the  command
               domainname  to  get the DNS domain name because it will show the
               NIS domain name and not the DNS domain name.  Use  dnsdomainname
               instead.
 
        -F, --file filename
               Read  the  host  name  from  the specified file. Comments (lines
               starting with a ‘#’) are ignored.
 
        -f, --fqdn, --long
               Display the FQDN (Fully Qualified Domain Name). A FQDN  consists
               of  a  short  host  name and the DNS domain name. Unless you are
               using bind or NIS for host lookups you can change the  FQDN  and
               the  DNS  domain  name  (which  is  part  of  the  FQDN)  in the
               /etc/hosts file.
 
        -h, --help
               Print a usage message and exit.
 
        -i, --ip-address
               Display the network address(es) of the host.
 
        -s, --short
               Display the short host name. This is the host name  cut  at  the
               first dot.
 
        -V, --version
               Print  version  information on standard output and exit success‐
               fully.
 
        -v, --verbose
               Be verbose and tell what’s going on.
 
        -y, --yp, --nis
               Display the NIS domain name. If a parameter is given (or  --file
               name ) then root can also set a new NIS domain.
 

NOTES

        The  address  families hostname tries when looking up the FQDN, aliases
        and network addresses of the host are determined by  the  configuration
        of  your resolver.  For instance, on GNU Libc systems, the resolver can
        be instructed to try IPv6 lookups first by using the  inet6  option  in
        /etc/resolv.conf.
