Adding a strange realserver

[David Darras]

Hello,

My lvs recently had a strange behavior. I have 3 realservers (with the 
same content) , and only 2 of them are loadbalanced. But my ipvs command 
displays the 3 realservers :

IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
FWM  1 wlc persistent 600
  -> 192.168.0.2:0              Route   1      0          0
  -> 192.168.0.3:0              Route   1      0          0
  -> 192.168.0.4:0              Route   2      0          0
FWM  2 wlc persistent 600
  -> 192.168.0.3:0              Route   1      0          0


The 192.168.0.2 doesn't appear in my configuration file. When i reload 
my director, 192.168.0.2 is deleted, but after a couple of hours, it's 
added again. Nothing about adding this realserver in the log.

Here is my config :

# Global Directives
checktimeout=5
checkinterval=10
#fallback=127.0.0.1:80
autoreload=no
logfile="/var/log/ldirectord.log"
quiescent=no

# for HTTP
virtual=1
        real=192.168.0.3:0 gate      1
        real=192.168.0.4:0 gate      2
        netmask=255.255.255.255
        service=http
        request="/root/hello.txt"
        receive="hello"
        scheduler=wlc
        persistent=600
        protocol=fwm
        checktype=negotiate

# for AOL proxys
virtual=2
        real=192.168.0.3:0 gate      1
        netmask=255.255.255.255
        service=http
        request="/root/hello.txt"
        receive="hello"
        scheduler=wlc
        persistent=600
        protocol=fwm
        checktype=negotiate

Any idea ?

Sincerely yours,
David
