Dear all,
I have this funny question:
on a DEC Unix box you can use getdomainname library call to get the
domainname (not NIS) extracted from the FQDN stored in utsname.nodename,
and this seems to work on Suns and AIX machines as well.
On a Slackware 3.0 linux one getdomainname returns '(none)' because it
reads utsname.domainname which is not set by domainname which is a link
to domainname-yp.
Note that uname does not read utsname.domainname at all and returns
utsname.nodename which is not the FQDN in contrast to the behaviour of
other Unix flavours.
This misconfiguration could be fixed in two ways:
1) deleting domainname from the utsname kernel structure and setting
utsname.nodename to the FQDN similar to what other Unix implementations
do and fixing getdomainname accordingly to it;
2) separating domainname and domainname-yp functions.
Take care,
Leonardo
