unable to connect to server: Remote system error - connection refused

Still i am getting same error.

rpcinfo: can't contact portmapper: RPC: Remote system error - Connection refused

We reconfigured NetWorker Portmapper. Opened 7939 to 9936.

Sorry, typing mistake. This two ports is also included.

You missed 2 most important ports in NW universe - 7937 and 7938.

In that case 2 things are happening:

- nsrexecd is not running

- something is still blocking comunication

If later one, then you can easily see that using telnet.  Do following:

- from backup server to telnet 7937

- from client do telnet 7937

This will verify if you are able to communicate with these boxes.  Alternatives:

- from backup server do:

rpcinfo -t 390113 1

- from client do:

rpcinfo -t 390113 1

what is the port settings on the firewall. say you have configured service ports range from 7937-9936 on the networker client, but how many ports are configured to allow the communication on the firewall. To make it simple, in a firewall enviornment it is best to open the required number of ports, rather than opening the entire port range. (opening the entire port range beats the purpose) of having a firewall

You may try setting the following:

1. delete the nsr peer information for the client (both client and server)

2. Configure the service ports range on the client from 7937-7947

Ensure that the same ports are opened on the firewall(TCP/UDP bi-directional) and then try to run the wizard.

I have configured the Ports bi-directionally on Firewall and Clients based on below calculation.

Number of Ports = 12 + 2*number of drives+ number of Tape Library = N no. of ports need to be open.

Services port range: 7937 to (7937+N) - Need to be open on firewall and Clients and no need to configure connection port(0-0) on clients.

Command: nsrports -S 7937-(7937+N) on clients and restart the networker client services.

Refer Example A: Calculate service ports on a bidirectional firewall Pg-11 from Configuring TCP Networks and Network Firewalls for EMC NetWorker.PDF

Below error i am getting from backup server to client but from client, it is taking very long time.

rpcinfo: RPC: Remote system error - Connection refused

program 390113 version 1 is not available

Di need to open 111 on firewall??

Hi Sabarna,

Please try opening 111 port on the firewall bidirectionally.

Thanks & Regards

Just to make sure... turn off firewall and see if the firewall is blocking you, or is something else. If it is firewall, and you are using enterprise solutions, like CheckPoint, login to a console of that firewall and monitor connection tryouts and correct the firewall rules according to blocked traffic seen in a monitoring window.

thanks, I checked  nsrexecd services was not running.  after running the service backup running fine.
