Hello All,

I currently manage a back up sollution for my company.

We currently have multiple Linux Servers within in a policy.

On examing the log files for any server within the policy in question it was discovered that a connectionis made to the master server every 15 mins for 3 seconds roughly.

Unsure as why this is the case, is this normal?

I have just discovered the Linux boxes in question all seem to have an oracle presence......surprise

Mine do that too, regardless of function. A bit annoying.

but it probably still applies to Linux:

GENERAL ERROR: Messages associated with NetBackup processes are appearing in the system logs
http://www.symantec.com/business/support/index?page=content&id=TECH22382

It does state:

These entries may appear in the messages log (Solaris /var/adm/messages) every 10 minutes (or the period the NetBackup scheduler is scheduled to start).  They can also appear more often when backups are running and connections to bpcd or vnetd are being made.

& further:

These messages will continue being sent to the system log (/var/adm/messages) regardless of any NetBackup debugging levels, debug logs or touch files.  These messages are informational only, and do not indicate a problem.

There are "solutions" for Solaris platforms, not sure how these would transfer to Linux.....

Has come up in discussion a few times:

tried ps aux | grep bpcd and then Try to telnet to localhost 13782
# netstat -natpul|grep 13782
telnet localhost bpcd
telnet localhost 13782
/usr/openv/netbackup/bin/bpcd -standalone

Are you using some kind of tcpwrapper (/etc/hosts.allow and /etc/hosts.deny) If so, maybe you have to add one line for bpcd allowing the master server and media servers to connect through bpcd's port


If xinetd is not installed, it may try /etc/inetd.conf, if neither areinstalled or available, it probably will start it as standalone.

Here is the bpcd on a client:

$ cat bpcd
# Service bpcd for NetBackup
service bpcd
{
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/openv/netbackup/bin/bpcd
disable = no
}

ckconfig xinetd on
Run: /sbin/chkconfig --list | grep bpcd
bpcd: on

its on, if its not, enable it and restart xinetd.
