Hi
I think I had this problem, only in my case I was not trying to run an
install script, I was just checking our DNS-config when installing a new
machine (knowing our network/DNS admins ...).
It was a matter of case, and the test just after the awk-script (if [
"X$PTR" != "X" ] && expr " $PTR " : ".* ${FQDN}[.] .*" >/dev/null;) is case
sensitive (which I'm not sure that it should be). If I understand correctly
(and I trust I'll be corrected...) domain names are supposed *not* to be
case sensitive (or possibly always in upper case), however, a DNS should
return names in the case they're entered (so there is an opportunity for
confusion ;-).
I'm not sure if I tweaked the script to be case-insensitive, or got the
DNS-admin to change case (or just didn't care)...
