Client can't connect

[Andre_Torres]

Hi everybody,

I made a installation in a HP-UX client, the installation gives me ok, but in the master server it gives me that it cannot connect to client. First I thought it was firewall, but the server administrator said it doesn't have a I firewall in this server. Tried telnet from master to this server and connected to port 13724. Ping works.

So I tried another test, pick the java administration console on my desktop and tried to connect to this server. Didn't work. Try to execute jnbSA with putty and Xming, and worked. With this window open, I've tried to make a manual backup, it gives me VxSS authentication error.

Both Master and Client HP-UX 11.31 in 7.5.0.4.

Netbackup 7.5 will first attempt connection on port 1556. If unsuccessful, then port 13724 will be attempted.

Have you confirmed successful forward and reverse name lookup between server and client?
Have you checked hosts entries on server and client or else DNS?

Please create bpcd folder under /usr/openv/netbackup/logs on the client.

Ensure hosts files and/or DNS is functioning correctly.

Clear NBU host cache on the server after confirming hosts and/or DNS:
bpclntcmd -clear_host_cache

Try the connection again from Host Properties.

If it fails, please check for log file in client's bpcd folder.  Copy file to bpcd.txt and upload as File attachment.

Have you confirmed successful forward and reverse name lookup between server and client?

Yes;

Have you checked hosts entries on server and client or else DNS?

Yes;

/usr/openv/netbackup/logs/bpcd created;

hosts and DNS looks like it is working;

Tried connection with host properties, error 58 again, and the bpcd folder is empty on the client.

Also tried bptestbpcd -client <client name> from the master server and gives me <16>bptestbpcd main: Function ConnectToBPCD(client name) failed: 25

cannot connect on socket

[revarooo]

If bpcd is empty on the client the connection from the server either never arrives at the client or the client is blocking access to the bpcd port.

On the client run:

bpclntcmd -self

bpclntcmd -pn

bpclntcmd -hn <media_server_where_you_run_bptestbpcd_from>

bpclntcmd -ip <returned IP from the command above>

on the media server where you ran bptestbpcd -client <clientname> run this:

bpclntcmd -hn <client_name>

bpclntcmd -ip <returned IP from the command above>

bpclntcmd -self

[Marianne]

Did you remember to clear host cache?

Please show us output of the following:

bptestbpcd -client <client-name> -verbose -debug

[revarooo]

bpclntcmd -pn showing nothing means that the connection is not going back to the master server or not coming back from the master server.

You have comms issues here.

On the Master server run:

telnet <clientname> 1556

telnet <clientname>13782

Does it connect?

[Andre_Torres]

Yeah, cleared host cache

[Andre_Torres]

Yes to both.

[Marianne]

Please show us all output from the top.

I am surprised to see only one connection attempt to bpcd :

09:32:42.530 [18604] <2> logconnections: BPCD CONNECT FROM <master server IP>.51485 TO <client IP>.13782 fd = 4

The default for 7.5 is to first attempt PBX (1556), then 13724 (vnetd), and only if both fail, try bpcd (13782).

Please show us processes running on client:

# ps -ef | egrep 'pbx_exchange|vnetd|bpcd' | grep -v grep

All of the following should be running: 

 /opt/VRTSpbx/bin/pbx_exchange
 /usr/openv/netbackup/bin/vnetd -standalone
 /usr/openv/netbackup/bin/bpcd -standalone

Please also go through this TN: http://www.symantec.com/docs/HOWTO72844 

[Andre_Torres]

I showed all output, its only this.

ps -ef | egrep 'pbx_exchange|vnetd|bpcd' | grep -v grep:

    root 21172     1  0 08:12:08 ?         0:00 /usr/openv/netbackup/bin/vnetd -standalone

    root 21202     1  0 08:12:08 ?         0:00 /usr/openv/netbackup/bin/bpcd -standalone

    root 13270     1  0  Nov 27  ?         0:00 /opt/VRTSpbx/bin/pbx_exchange

[Marianne]

Have you changed default connect options for this client? Connect to bpcd port is not NBU 7.5 default.

Please check output of :

bpclient -client <client_name> -L

If telnet to bpcd is successful, and bpcd is running on the client, then I find it very strange that NOTHING is logged to client's bpcd folder...
Please verify location and spelling of the folder?

[revarooo]

What does this say from the client:

bpcltncmd -hn <master_server> 

does it return the correct IP?

[Andre_Torres]

Yes

[Andre_Torres]

No changes were made.

[rajeshthink]

BPCD directory is not getting update then its clear issue of NBU installtion . I have seen this issue time and again from the time 7.1 has been enrolled.

My personal expirences says , Uninstall and reboot the server and then try to install with right user permission. ( mostly this help).

Cheer,

Rajesh Kumar

[Marianne]

We are not going to resolve this with  'yes' and 'no' answers and without actual output of commands as per our requests.

Best that you log a Support call.
A Symantec engineer will be able to view actual output of commands and verify hostnames and IP addresses via Webex session.

[revarooo]

Exactly, we are not seeing the relevant information to help you. Log a call as Marianne has suggested.

If connectivty is working both ways via telnet yet bptestbpcd is failing, something tells me we are missing vital information to help you.

It could be that the Master is trying to connect on a different interface to the client (or vice versa) and therefore connectivity stalls, yet when using telnet it uses the correct interface.

[Andre_Torres]

I don't want to call support because I've noticed that he forums are better in this little problems.

If you cannot show us the hostnames/IPs then support will be better than the forums. Trust me. I know!
