Windows Server 2012 & 7.5.0.6

[Kev_Lamb]

Hi,

I have installed the Win2012 7.5.0.6 client onto a Win Server 2012 client but am having difficulties connecting from the Master Server to the client.

The install completed wihout error and I can run the Backup/Restore client from the Server; however, when I try to connect to the client from the Master GUI I get Connection Requested By Invalid Server, the Master was correctly placed in the relevant box on install and I have double checked the client GUI and this is correct.

If I run the usual connection tests from the master server I get the following:

bpclntcmd -hn lonbfbvmconn2

host lonbfbvmconn2: LONBFBVMCONN2.corp.ad.timeinc.com at 10.132.113.127

aliases:     LONBFBVMCONN2.corp.ad.timeinc.com     lonbfbvmconn2     10.132.113.127

telnet lonbfbvmconn2 bpcd

Trying 10.132.113.127...

Connected to lonbfbvmconn2.corp.ad.timeinc.com (10.132.113.127).

Escape character is '^]'.

bptestbpcd -host lonbfbvmconn2   

<16>bptestbpcd main: Function ConnectToBPCD(lonbfbvmconn2) failed: 46

server not allowed access

bfbackup.ipcmedia.com:/root> bptestbpcd -client lonbfbvmconn2

<16>bptestbpcd main: Function ConnectToBPCD(lonbfbvmconn2) failed: 46

server not allowed access

So as you can see I can quiet clearly access the bpcd port via Telnet and the bpclntcmd returns the correct client details but the bptstbpcd fails.There is no firewall active on the client and the client and master can do a reverse lookup on each other and can ping also.

Anyione got any ideas as I am at a loss

Setup a bpcd log on the client to see why it actually denies access

It may just be a FQDN thing and you will then need to either add a hosts file entry to the client and / or Master / Media Servers or add the FQDN to the clients server list

Create the bpcd directory - try and connect to it again and post the resulting log file

[Kev_Lamb]

Just done that, looking through the log (attached) it is stating that my master server is not a master or a media.....

[Kev_Lamb]

Just had a look at the Reg Key in HKEY_LOCAL_MACHINE\Softeare\veritas\netbackup\currentversion\config and the Server key includes the following:

bfbackup.ipcmedia.com
bfbackup
10.132.112.22

So it is listed in the software as a server in all the FQDN ways

What does bptestbpcd show? I don't recall the options off the top of my head, but it checks connections to clients. What about bpclntcmd -hn (option) and bpclntcmd -ip (IP)? This checks lookups (forward and reverse) from the NBU side.

[Kev_Lamb]

Chack22 if you take a look at the initial post the bpclntcmd returns ok but the bptesbpcd fails with server not allowed access, the telnet to the bpcd port works fine, all entries on the client are correct and I have even put the master in the host file and can do forward & reverse DNS from client to master and master to client.

[CRZ]

I may be nuts, but something stood out from your log...

17:22:30.901 [2060.2032] <2> bpcd peer_hostname: Connection from host bfbackup.ipcmedia.com  (10.132.112.22) port 51386
...
17:22:31.151 [1108.536] <4> bpcd valid_server: bfbackup.ipcmedia.com  is not a master server
17:22:31.151 [1108.536] <16> bpcd valid_server: bfbackup.ipcmedia.com  is not a media server either

It sure looks like there's an invisible space appended to the reverse DNS of your master (I'm seeing two spaces instead of the one which I would expect) which is causing NetBackup to fail to match the name "bfbackup.ipcmedia.com " to "bfbackup.ipcmedia.com" because, to NetBackup, the strings ARE technically different...

Can you recheck the host file on the client and see if there's something you can edit?  (I'm assuming this isn't a problem for other clients so it's something local to this particular one, but you probably know your DNS better than I do)

[Kev_Lamb]

Hi,

I have checked and rewritten the hosts file on the Win2012 server and this still fails, I even removed the hosts file and checked I could still do a reverse nslookup to the Master from the client and thsi was Ok.

Still getting the same entries in the bpcd log about the master and media server.

As your entries look OK try this:

1. See what the Browser registry key is set to - this should match the Client_Name key

2. Run this twice on the client:

\program files\veritas\netbackup\bin\blclntcmd -clear_host_cache

3. Check what the Port_BPCD key value is - it should be 13782

4. Re-start the client service on the client

5. Try to connect again

Also on the client run bpclntcmd -sv to see what it brings back

[Kev_Lamb]

Hi Mark

The Reg keys look correct (see attached doc) I have ran the clear_cache option twice and restarted the client services, also the output of the bpclntcmd -sv returns 7.5

I am at a loss as to why it cannot relate to the Master Server

Kev

[Mark_Solutions]

There doesn't look to be enough components in the registry there

Could you try re-installing (run a repair) on the client - make sure AV is turned off and that you do everything using the Run As Administrator

[Kev_Lamb]

Uninstalled the client then ran a clean install as Admin, same issue

I have just removed the client and then cleared all relevant directories and cleaned the registry, rebooting the server, going to run another clean install and see what happens, not confident though

[Mark_Solutions]

OK - do you have a Media Server too?

If so add that to its configuration and see if you can connect from that

[Kev_Lamb]

I have two media server, one Windows and one Linux, I did add both to the config and they both returned the same fault as the master where the server is refused connection.

[Mark_Solutions]

OK - make sure you have the bpcd and bpinetd log folders - increase logging (via its BAR GUI) - re-start the services and try to connect again

Then post the logs

And just in case .. try setting the NetBackup Client Service and NetBackup Legacy Network Service to use a Domain Admin account to see if that makes any difference

[Kev_Lamb]

Set logging to 2, used a domain admin account to start the services, still get the same issue though :(

Log files are attched

Just ran the  bptestbpcd -client lonbfbvmconn2 -debug from my linux media server (lonbfbreddev) and this returns with a clean connection:

Also get a clean return from the windows media server also, so it is something with the master server it is having an issue with

[Mark_Solutions]

How many domains are involved here and is DNS good, if not you will need to use hosts files.

On the Master Server what is the value of the regsitry key Port_BPCD?

It really does look like a name resolution issue or similar - when it compares the masters name with the masters name it cannot do its own lookup and that is where it goes wrong as it cannot extract anything from its own cache.

How many networks does the client have?

Just as a test could you try this ..

In the registry change the Client_Name and Browser to be the short name of the client and the server to be the short name of the Master and Media Servers

Then, also on the client, in its hosts file add the Master, Media and itself in short format

Re-start the client services, do a couple of clear_host_cache commands and see if anything changes

Also make sure AV and Firewalls are turned off while you check this out

[Kev_Lamb]

Hi 

There are two domains corp.ad.timeinc.com & ipcmedia.com, none of my other 300 clients have a problem with this only the new 2012 ones

I have changed the entries in the reg to shortname and also in the hosts files, cleared the cache and still get the same response from the Master Server only.....

Thanks for all your help with this by the way
