socket write failed (Status 24)

What is NBU version on Client ??

pls run on master and post o/p

/usr/openv/netbackup/bin/admincmd/ ./bptestbpcd -client <redhat_host> -debug

So, are you getting status 24 when you try to connect or during backup (connection fine, backup fails with 24 after some data transmitted).

If the same connect error as the post you are referring to, please create bpcd log dir on client.

Do 'bptestbpcd -client <client-name> -verbose -debug' on server.

Please post bptestbpcd output as well as client's bpcd log.

You need to confirm that the client can resolve master's IP to a hostname that appears in client's bp.conf SERVER list. Create /etc/hosts entries if DNS is not used or reverse lookup not enabled.

You also need to confirm that vnetd (port 13724) is open in both directions. Iptables normally need to be disabled as well on Linux.

can you post the bpcd log from the client as well please - this often has the answer - thanks

hi, thanks for your attention...

the version on NBU client is 6.5.0,  Linux 2.6.9-78.0.25.0.1.ELsmp

hi, dear,thanks for taking care of this.

yes, I've posted the verbose  "'bptestbpcd -client <client-name> -verbose -debug' " output in the reply to Yogesh9881....

we use DNS and it works well. client can reslove master's hostname and Ip.

no firewall between port 13724,the same network section

hi, dear,thanks!

I will create logs on client and posted the result for you.

app-p1 is the client

 san-oraadmin-1 is NBU master.......

[root@app-p1 ~]# /usr/openv/netbackup/bin/bpclntcmd  -hn  san-oraadmin-1.fin.activenetwork.com

Are bpcd and vnetd LISTENTING on the client?

The following commands can be used to verify that vnetd and bpcd are listening:

netstat -a | grep bpcd
netstat -a | grep vnetd

The output from these commands should show the following outputs, respectively:

# netstat -a | grep bpcd
tcp        0      0 *:bpcd                      *:*                         LISTEN
# netstat -a | grep vnetd
tcp        0      0 *:vnetd                     *:*                         LISTEN

Also check if iptables is running and disable it:

client# /sbin/service iptables status
Table: filter
...

Stopping this service allows access and results in successful backups:

client# /sbin/service iptables stop
client# /sbin/service iptables status
Firewall is stopped.

I thought we used DNS...sorry

yes, it works! thanks Yogesh9881..........

thanks everybody here
