Just to confirm that their is definitely a small bug in ldirectord,
The bit that checks if the RIP has already been checked doesn't allow
for the same RIP but with a different virtual host setting (i.e.
different web site)
I can't program so I've just riped out these bits from (v1.99) to solve
the problem on my site....
Maybee someone can change it to take account of virtual servers as well
as just RIPs?
In sub ld_main()...
REAL: foreach my $r (@$real) {
my $real_id = get_real_id_str($r, $v);
#foreach my $tmp_id (@real_checked) {
# if($real_id eq $tmp_id) {
# &ld_debug(3, "Already checked: real
server=$real_id (virtual=$virtual_id)");
# next REAL;
# }
#}
and is sub service_set()....
# Check each virtual service for the real server and make
# changes as neccessary
#foreach $v (@VIRTUAL){
# Use found rather than relying on tmp_id being
# set when we leave the foreach loop. There
# seems to some weirdness in Perl (5.6.0 on Redhat 7.2)
# my $found = 0;
# my $tmp_id;
# my $virtual_id = get_virtual_id_str($v);
# foreach $tmp_id (@$virtual) {
# if($virtual_id eq $tmp_id) {
# $found = 1;
# last;
# }
# }
# if ($found == 1) {
if ($state=~/up/i) {
_service_up($v, $r, $force);
&ld_debug(2, "Enabled server=$$r{server}");
} elsif ($state=~/down/i) {
_service_down($v, $r, $force);
&ld_debug(2, "Disabled server=$$r{server}");
}
# }
#}

I think I've run into a problem with the feature of ldirectord that only
checks a real servers status once (even if it occurs in multiple
virtual servers)
Waiver:Not convinced because a similar set up seemed to work.
With the following config where only wwwtest.blast.com is set to
weight=0..
ALL of the 192.168.3.60:80 servers in all of the VIPs go offline!
Tested in v1.99 & v1.132

Ps. I think this is the code that effects it?
REAL: foreach my $r (@$real) {
my $real_id = get_real_id_str($r, $v);
foreach my $tmp_id (@real_checked) {
if($real_id eq $tmp_id) {
&ld_debug(3, "Already checked: real
server=$real_id (virtual=$virtual_id)");
next REAL;
}
}
Thanks in advance for any help..

Malcolm Turnbull.
