I'm starting a new LVS-DR setup with ldirectord but am unable to get it
working. I started with trying to set up a single director server with a
single real server.
My ldirectord.cf:
------------------
checktimeout=8
checkinterval=5
autoreload=yes
logfile="/var/log/ldirectord.log"
quiescent=no
fork=yes
virtual = xx.xx.xx.xx:80
fallback = 127.0.0.1:80 gate # if no real servers are available
real = 10.0.0.2:80 gate 10 # weight of 10
scheduler = wrr # weighted round robin
persistent = 7200
protocol = tcp
service = http
request = "test.php"
receive = "Success"
checktype = negotiate
------------------
The director starts up fine, I see no errors in the logfile:

------------------
When why I try to send any traffic to the xx.xx.xx.xx IP address, it seems to
go nowhere. My real server never sees the incoming traffic (using tcpdump).
Using tcpdump on the ldirectord server shows that it is polling the "test.php"
file successfully very often, but no further traffic is going out.
Results of: ipvsadm -L
------------------
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP xx.xx.xx.xx wrr persistent 7200
-> 10.0.0.2:www Route 10 0 0
------------------
When I try to curl xx.xx.xx.xx from anywhere else on the network, the InActConn
increments (if I try it 12 times within a minute, it goes up to 12
InActConn's), but nothing is getting served, not even so much as an ACK-SYN
comes back.
I am really stuck at this point and have no idea what to try, there seems to be
very little documentation anywhere on how ldirectord actually works except the
manpage. All documentation online seems to be only about setting up clustering
services like heartbeat/pacemaker/keepalived to manage director failover and
nothing about actually setting up a working director.
Any suggestions for what to try next would be very welcome.
