Unable to create a signing request to server(agent to server communication issue)

edit

Hi All,

It seems that I am having some issue with creating a signing request from agent to server.

client can ping sever and vice-versa. Even they can do ssh to each other.

I am unable to understand why client is not able to create a signing request for server?

At server:

  jim@puppet:~$ ps -aef|grep 8140|grep -v grep
jim@puppet:~$ ps -aef|grep puppet|grep -v grep
avahi      532     1  0 10:51 ?        00:00:00 avahi-daemon: running [puppet.local]
root      1322     1  0 10:52 ?        00:00:09 /opt/puppetlabs/puppet/bin/ruby /opt/puppetlabs/puppet/bin/mcollectived --pid=/var/run/puppetlabs/mcollectived.pid --config=/etc/puppetlabs/mcollective/server.cfg --daemonize
root      1612     1  0 10:53 ?        00:00:00 /opt/puppetlabs/puppet/bin/ruby /opt/puppetlabs/puppet/bin/puppet agent
jim@puppet:~$

At Client:

[root@agent1 ~]# puppet agent --test
Info: Creating a new SSL key for agent1.netgear
Error: Could not request certificate: Connection refused - connect(2) for "puppet" port 8140

Again at client side:

[root@agent1 ~]# telnet puppet 22

What might be the reason for this and how to have it resolved?

Any help would be greatly appreciated !
