GETHOSTID(3) BSD Library Functions Manual GETHOSTID(3)NAME
gethostid, sethostid -- get/set unique identifier of current host
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
long
gethostid(void);
void
sethostid(long hostid);
DESCRIPTION
The sethostid() function establishes a 32-bit identifier for the current processor. The id, intended to be unique among all UNIX systems in
existence, is normally a DARPA Internet address for the local machine. This call is allowed only to the super-user and is normally performed
at boot time.
The gethostid() function returns the 32-bit identifier for the current processor.
This function has been deprecated. The hostid should be set or retrieved by use of sysctl(3).
SEE ALSO gethostname(3), sysctl(3), sysctl(8)BUGS
32 bits for the identifier is too small.
HISTORY
The gethostid() and sethostid() syscalls appeared in 4.2BSD and were dropped in 4.4BSD.

gethostid, sethostid - get or set the unique identifier of the current host
SYNOPSIS
#include <unistd.h>
long gethostid(void);
int sethostid(long hostid);
DESCRIPTION
Get or set a unique 32-bit identifier for the current machine. The 32-bit identifier is intended to be unique among all UNIX systems in
existence. This normally resembles the Internet address for the local machine, as returned by gethostbyname(3), and thus usually never
needs to be set.
The sethostid call is restricted to the superuser.
The hostid argument is stored in the file /etc/hostid.
RETURN VALUE
gethostid returns the 32-bit identifier for the current host as set by sethostid(2).
CONFORMING TO

B.4.4.1. SVr4 includes gethostid but not sethostid.

Hi there,
Honestly i'm not much of a code guy but i found some short piece of code over the net which i need to compile in my Solaris machine (in order to change my hostid).
As far as i read - i need to use the gcc to compile this short text file making it an executable file.

Hi,

I did found few threads but all of them either have broken links to all kinds of scripts or not described simply for some UNIX beginers user like me.
Can anyone assist me?

There is no /etc/hostid file.
I know that there is no relationship between with MAC address and hostid. There are a lot of scripts on the net but how can I exactly do in my case. :rolleyes: (4 Replies)
