    Hi,

    I followed http://www.howtoforge.com/efficient...d-cluster-on-centos-5.3-direct-routing-method and changed it to load balance smtp port 25.
    But I can not get a listening port 25 on my server.

    Some configs:
    -bash-3.2# ip addr sh eth0
    2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:16:3e:4b:df:69 brd ff:ff:ff:ff:ff:ff
    inet 178.21.112.162/24 brd 178.21.112.255 scope global eth0
    inet 178.21.112.169/24 brd 178.21.112.255 scope global secondary eth0:1
    inet6 fe80::216:3eff:fe4b:df69/64 scope link
    valid_lft forever preferred_lft forever

    my /etc/ha.d/ldirectord.conf:
    checktimeout=30
    checkinterval=2
    autoreload=yes
    logfile="/var/log/ldirectord.log"
    quiescent=no
    virtual=178.21.112.169:25
    fallback=127.0.0.1:80
    real=194.145.200.17:25 gate
    real=194.145.200.171:25 gate
    service=smtp
    persistent=100
    scheduler=lblc
    protocol=tcp
    checktype=negotiate

    In /var/log/ldirectord.log:

    Why isn't anything listening on port 25?

    Change
    Code:
    fallback=127.0.0.1:80
    to
    Code:
    fallback=127.0.0.1:25

    Hi,

    But that is the fallback server, that isn't the port 25 listening right?

    Have you tried it? If it doesn't work, what's the output of
    Code:
    netstat -tap
    ?

    strange thing is that heartbeat does not start ldirectord, this is my haresources:

    When I start ldirectord I can connect to port 25 but it only forwards the traffic to server2 (171 ip).
    When I stop server2 Qmail no failover to server 1 is being made by ldirectord..

    loadbalancer is fedora c12 (normal ip 194.145.200.86 - vip 194.145.200.87)
    realserver 1 is centos 5.4 194.145.200.17
    realserver 2 is centos 5.4 194.145.200.171
