hostname on Solaris

Hi All,

I am wondering how does the hostname command decides what is the actual hostname. Where does the command take the information from?

From /etc/ hostname.<interface> name is the file which hostname command read to decide the hostname of the system.

I don't have access to a Solaris system right now to check for sure, but the contents of /etc/nodename are probably important, too.

Actually not, especially as you can have plenty of physical interfaces but have only one hostname at a given time.

Hostname initial setting is done by reading the /etc/nodename file.
DHCP, bootp or root might change the hostname later.

On Solaris the `hostname` command is a shell script that runs `uname -n` (and uses `uname -S ${1}` to set the hostname). I ran a `truss uname -n` to see if I could spot the location in memory or disk easily but I was not able to figure that out.

During boot the sysid tools check /etc/nodename and set the hostname of the system to the contents of that file.

The uname command uses the uname system call. The host name is stored in a kernel structure named "utsname".

True. But the change still has to be saved somewhere
