Hi thank for you answer, it seem tha packeg is not forward to the
realserver, in this case the loadbalancer and realserver are the same node,
nmap 172.17.1.13
Nmap scan report for 172.17.1.13
Host is up (0.0043s latency).
Not shown: 998 closed ports
PORT STATE SERVICE
25/tcp open smtp
it says open but a telnet to the virtual ip dosen't respond
ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 172.17.1.13:25 rr
-> 172.17.1.15:25 Route 1 0 0
-> 172.17.1.16:25 Route 1 0 3
This is the partial conf
virtual_ipaddress {
172.17.1.13/24
}
# Invoked to master transition
notify_master "/etc/keepalived/bypass_ipvs.sh del 172.17.1.13"

# Invoked to fault transition
notify_fault "/etc/keepalived/bypass_ipvs.sh add 172.17.1.13"
}
# describe virtual mail server
virtual_server 172.17.1.13 25 {
delay_loop 15
lb_algo rr
lb_kind DR
persistence_timeout 50
protocol TCP
real_server 172.16.1.16 25 {

}
}
real_server 172.17.1.15 25 {

}
Thanks ind advance for your time and effort. Regards
