Host Properties returns - "invalid error number"

[Michele_2]

Hi,

I have just installed the netbackup client on some new Linux servers.

Netbackup 5.1 MP4

Oracle Enterprise Linux 5.1

When I try to do the Host Properties it timesout with "invalid error number"

The bprd log shows -

15:55:10.609 [9913] <2> bprd: socket fd from accept() is 7

I can ping from the master-server to the client and vice versa.

I can nslookup from the master-server by both hostname and ip address - and vice versa.

I issued the bpclntcmd on both the master-server and client as well as another linux server that is working fine and -hn for hostname, -ip for ipaddress, and -self work. When I issue the -pn switch on the client it only returns a command prompt and the bprd log shows -

bp.conf looks fine on the client.

I would appreciated any help with this issue!

Thanks.

as this is a new client and the first time you are trying to connect to it from the master server you need to do the first steps of on communication.

check the dns entries for the new client.

does it have both a forward and reverse.

can you ping the client from the master both by name and ip

can you ping the master from the client both by name and ip

check to see if you have any ports closed that nb needs.

[Michele_2]

Thanks for you quick response!

I have checked the dns and all is working. I can nslookup from the master-server to the client by hostname and ip. Also, nslookup from the client to the master-server by hostname and ip. Ping also works both directions by hostname and ip address.

I do not have any ports closed (that I know of) - is there a command I can issue to verify that. Also, the bprd log does show that a connection is made -

connected_peer: Connection from host bkvlrac01.ad.swfwmd.net, 10.10.24.30, on non-reserved port 13301

As I said, this is on Oracle Enterprise Linux (Red Hat based) 5.1 kernel 2.6.18-53.el5. I have three servers with this os and all three have the same issue.

Thanks!

Check xinetd for proper configuration.

Try using "bpclntcmd" to test basic connectivity from NetBackup's perspective.

use "netstat -a" to check that the appropriate ports are open.

I also believe that Linux has it's own build in firewall that you may want to check to see who it's configured. (I''m not familiar with it though).

Thanks for the quick response. I have used the "bpclntcmd" and it works for the -hn and -ip switches, not for the -pn.

Xinetd is running and my xinetd.conf is the default - is the a specific entry needed?

In the linux desktop 'Service Configuration' I see "bpcd" and "bpjava-msvc' checked.

The built in firewall is disabled.

Thanks!

Test the bpcd port on the master:

From the master: telnet localhost 13782

From the client: telnet <master> 13782

It should connect, wait for you to hit ENTER and then drop you off.  Does that happen or do you get an error?

[Michele_2]

With the mention of xinetd.conf and some more googling ;) I was able to get it to work.

Added the following to xinetd.conf -

service bpcd
{
socket_type     = stream
protocol        = tcp
 wait            = no
user            = root
server          = /usr/openv/netbackup/bin/bpcd
# server_args     = bpcd
#only_from       = ........removed...........
}

service vopied
{
socket_type     = stream
protocol        = tcp
wait            = no
user            = root
server          = /usr/openv/netbackup/bin/vopied
# server_args     = vopied
#only_from       = ........removed...........
}

service bpjava-msvc
{
socket_type     = stream
protocol        = tcp
 wait            = no
user            = root
server          = /usr/openv/netbackup/bin/bpjava-msvc
server_args     = -transient
#only_from       = ........removed...........
}

Thanks to all for the help!
