Client can't connect

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.

    So - you have followed my advice in my previous post??

    Have you tried to remove the client software and reinstall? Seems you've been having problems with software installation in your environment...

    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.

    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

    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

    Did you remember to clear host cache?

    Please show us output of the following:

    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?

    Yeah, cleared host cache

    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
