I am running an instance in AWS and i have installed HAProxy but when i run start HAProxy service i got below error.(OS-Centos)

[ALERT] 108/173540 (10131) : Starting frontend http-in: cannot create listening socket [;5988]

Its a simple configuration

maxconn 256
mode tcp
timout connect 5000ms
timout client 50000ms
timeout server 50000ms
frontend http-in
bind *:1-65535
default_backend backend_servers
server sv1

Please help

You are listening the all 65535 ports on all IP addresses. Some ports are not available, because they are used otherwise.

Yes…You are right.Ports are unavailable not because they are being used but they were not enabled. As soon as i add a iptable rules to enable them, i am bale to start the service… Thanks a lot…
