I just tried out removal of bind-utils on a soon to be retired machine. It seems fine with the caveat that we lose /bin/host and /bin/dig

Perhaps a perl script might suffice to emulate 'host' on machines that might need the occasional networking debug session. Just typed this up, so FWIW:

use Net::DNS;

my $res = Net::DNS::Resolver->new(); my $sought = $ARGV[0]; my $a_query = $res->search($sought); if ($a_query) { foreach my $rr ($a_query->answer) { if( $rr->type eq 'A' ){ printf("%s has address %s\n", $sought, $rr->address); } elsif( $rr->type eq 'CNAME' ){ printf("%s is an alias for %s\n", $sought, $rr->cname); $sought = $rr->cname; } } } else { warn "Unable to obtain a record for $ARGV[0]: ", $res->errorstring, "\n"; }

Are you running sssd? Are you connected to the AD?
