My first node is running and second node is not running in this case I tried telnet from second node to first node. Following is the stdout
# telnet 10.96.10.207 7000 Trying 10.96.10.207... Connected to 10.96.10.207. Escape character is '^]'. quit Connection closed by foreign host. I see the same output for 7199 & 9160 ports. is this correct. I am not seeing the telnet session as something like telnet> ---------- But when I tried with 7001. I am seeing the below output # telnet 10.96.10.207 7001 Trying 10.96.10.207... telnet: connect to address 10.96.10.207: Connection refused I see the same output for 61620 & 61621 ports ---------- Please suggest On Thu, Aug 29, 2013 at 11:23 AM, Andrey Ilinykh <ailin...@gmail.com> wrote: > To be sure ports are open try to connect from one node to another: > > telnet <node ip> 7000 > > try all ports. > > Andrey > > > On Wed, Aug 28, 2013 at 10:41 PM, Dinesh <dinesh.gad...@gmail.com> wrote: > >> Hi John, >> >> I had my firewall disabled in both the nodes >> To make sure.
