No route to host

Seems you need to get hold of your network team.

What happens if you ping the client name?

Thanks Marianne for your reply

I can ping the client from the master and vice/versa

[root@nbucom2 ~]# ping xobi.my.company.com
PING xobi.my.company.com (xx.xx.xx.xx) 56(84) bytes of data.
64 bytes from xobi.my.company.com (xx.xx.xx.xx): icmp_seq=1 ttl=61 time=0.295 ms
64 bytes from xobi.my.company.com (xx.xx.xx.xx): icmp_seq=2 ttl=61 time=0.305 ms
64 bytes from xobi.my.company.com (xx.xx..xx.xx): icmp_seq=3 ttl=61 time=0.280 msny

are you using DNS for name resolution?

if yes, please add client name and IP in master server /etc/hosts and see how its working.. 

Did you do bptestbpcd shortly after adding entries to hosts files?

If so, remember to clear NBU host cache: 
bpclntcmd -clear_host_cache

Please check that iptables is stopped and disabled on Linux client.
If firewall between server and client, check that port 1556 is open in both directions.

Thanks Nagalla, Marianne

Nagalla,I added the client name and IP to the master and it still can't connect to our NBU master

Marianne,

I did the bptestbpcd again after adding the entries in the hosts file (see below)

[root@nbucom2 admincmd]# ./bptestbpcd -client xobi

Marianne, to clear the NBU host cache, the command is done on the master nbu server correct? Just checking I have never used the command before

Also, I am going to check on the iptables and the port

Thanks again

hi 

what is the output of below commands in Master server

bpclntcmd -hn xobi.my.company.com

bpclntcmd -ip <client Ip address>

grep xobi /etc/hosts

grep <Client IP> /etc/hosts

nslookup xobi.my.company.com

nslookup <client Ip>

ping xobi.my.company.com

ping <Client IP>

check for correct paths and existence of vnetd on that path NOTICE incorrect path for vnetd listed.

under  /etc/xinetd.d we need to confirm if there are files bpcd & vnetd

these files have the script for the path for bpcd and vnetd 

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

}
 

service vnetd
{
        socket_type = stream
        protocol = tcp
        wait = no
        user = root
        server = /usr/openv/bin/vnetd
        disable = no
        instances = UNLIMITED
        cps = 1000 1

}
