Nessus Client Connection Refuses

I have 2 machines: One with Ubuntu Linux Server and the other with the more common Ubuntu Linux. I have installed Nessus server and the client with packages from nessus.org

I have confirmed that the server has started:

Every time I connect, I get the message "It was not possible to connect to the remote host - make sure the host IP and port are correct and that the Nessus Server is running".

Does anyone have any ideas for resolving this? Thanks.

root@flagship:~# /etc/init.d/nessusd restart
$Shutting down Nessus : .
$Starting Nessus : .
root@flagship:~#

nessusd.conf:
# Port to listen to (old NTP protocol). Used for pre 4.2 NessusClient connections :
listen_port = 1241

# Port for the Nessus Web Server to listen to (new XMLRPC protocol) :
xmlrpc_listen_port = 8834

Have you checked that the client machine can see the server's open ports? It might be a firewall in the way?
Try an nmap scan from the client machine (apt-get install nmap):

nmap -p1241,8834 -PN -n -sV <nessus_server_IP_address>

I've just installed nessusd on a windows machine and the server won't even start until I've registered it and got an activation code. Have you done that?

Sweet. I wondered why I didn't have the option to install a client on windows. Haven't used nessus since they changed all the licensing and if I was going to use something like it, I'd use OpenVAS instead.
So, are you up and running then?

I have heard of OpenVAS, but I never had the chance to try it. In any case, I am up and running.

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection. Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
