sys_id(4)							     sys_id(4)

NAME    [Toc]    [Back]

     sys_id - system identification (hostname) file

DESCRIPTION    [Toc]    [Back]

     The file /etc/sys_id contains the name by which the system	is known on
     communications networks such as the Internet and UUCP.  The name can be
     up	to 64 alphanumeric characters long and can include periods and
     hyphens.  Periods are not part of the name	but serve to separate
     components	of a domain-style name.	 For example:


     During system startup this	file is	read by	the script
     /etc/rc2.d/S20sysetup and the contents are	passed as a parameter to
     hostname(1) to initialize the system name.	 Once this has been done, this
     name is returned by the commands hostnam
 and by the
     system calls gethostname(2) and uname(2).	uname(1) returns only the
     first eight characters up to the first period.
