can't connect to client  (58)

These are some of the things I tried before reaching out to everyone.

- I can ping the client in question.

- Netbackup can see this clients properties under Host Properties

- I can ping the master from the client, and the client from the master successfully

- I ran the bptestbpcd.exe -client client123 on the master; returned the right ip info.

- Tried backing up the client using it's ip address; same result.

The jobs do not fail immediately.

This is a 8.1.1 environment; master is a Windows 2012 cluster and media servers are appliances.

Client is a Windows 2012 physical server.

Your help greatly appreciated.

Under Host Properties – Clients, this particular client did not have any servers listed in the “Media Servers” tab.

They were all listed under the “Additional Servers” tab.

You need to run bptestbpcd on the Appliances.

Ensure connectivity (forward and reverse lookup as well as port connectivity) in all directions between media servers and clients.

I think I found something on the appliance.

mediaserver124:/home/maintenance # bptestbpcd -client server123.corp.com
<16>bptestbpcd main: Function ConnectToBPCD(server123.corp.com) failed: 25
<16>bptestbpcd main: cannot connect on socket
cannot connect on socket

you have declared in hosts file the name and ip of the client and master/media?

Try below and check once.

1. update /etc/hosts file of media server with client short and FQDN names. Also add master and media into clients hosts file.

2.try to do nslookup client and ensure it is resolving the DNS.

3.use the command ./bpclntcmd to check forward and reverse lookup after adding hosts file entry.

4.If the server are under the firewall then ensure port 1556,13782,13724 working between master,media and clients each other.

5.perform the step ./bpclntcmd -clear_host_cache and try to run the backups.

Prathap..

I can currently ping both from the backup client.

Master is a cluster...can you check on which physical node master is active and add both the nodes including cluster Virtual name in the clinets winodws registry server list and hosts file.

You can see that the problem is with port connectivity.
Port 1556 needs to be open in both directions.

The fact that you can 'ping both from the backup client' is not enough.
NBU needs all of these to ensure connectivity between media server(s) and client(s):
- forward and reverse name lookup in both directions
- port connectivity in both directions (1556)

Please create bpcd log folder on client(s), then run bptestbpcd from Appliance again - remember to add -debug and -verbose to the command.
Is anything logged in bpcd on client? 
If not, there is a firewall problem.
