Subject RE: Reg Exception in Kafka
Date Wed, 29 Jan 2014 06:10:48 GMT
I don't think so. I forgot to include the ifconfig  output. Actually the public IP is not one
of the IP configured in the Ethernet interfaces.
Only the Local IP is configured in eth0. 
Is there any solution to this?

Ifconfig O/P:

eth0      Link encap:Ethernet  HWaddr 22:00:0A:C7:1F:57
          inet addr:10.X.X.X  Bcast:10.199.31.127  Mask:255.255.255.192

Could it be a port conflict?

Thanks,
