What agent are you using (nrpe,check_by_ssh, etc)? Is this server a windows or linux box? Is the agent service running on the remote host?

[inderraw]

Dear Team,

I am using NS client agent, which is running on server.

Are you using check_nt or check_npre to connect to to the nsclient agent?
nrpe uses port 5666 by default whereas check_nt uses 12489.

Can you nmap or telnet to the ports in question from a different box?

[inderraw]

Dear team,

I am telneting but not getting any solution.

telnet 54.243.141.244 5666

I see you tried port 5666, which would imply nrpe. Are you sure you enabled and configured nrpe in the remote hosts' nsclient config? If 5666 is not responding, either nsclient is not running, you still have firewall issues, or you are not using nrpe (you would be using nt_client instead).
Try:

Code: Select all

telnet 54.243.141.244 12489
