New LINUX client connect failure

Hi, I have installed the Netbackup client on a Red Hat LINUX server, but when I attempt a backup it fails to connect with the following errors: 12/07/2016 12:34:52 - Info bpbrm (pid=8316) connect failed STATUS (18) CONNECT_FAILED 12/07/2016 12:34:52 - Info bpbrm (pid=8316) status: FAILED, (44) CONNECT_TIMEOUT; system: (10036) A blocking operation is currently executing. ; FROM 0.0.0.0 TO rhel-dell 10.129.216.55 bpcd VIA pbx 12/07/2016 12:34:52 - Info bpbrm (pid=8316) status: FAILED, (44) CONNECT_TIMEOUT; system: (10036) A blocking operation is currently executing. ; FROM 0.0.0.0 TO rhel-dell 10.129.216.55 bpcd VIA vnetd 12/07/2016 12:34:52 - Info bpbrm (pid=8316) status: FAILED, (44) CONNECT_TIMEOUT; system: (10060) Connection timed out.; FROM 0.0.0.0 TO rhel-dell 10.129.216.55 bpcd 12/07/2016 12:34:52 - Error bpbrm (pid=8316) Cannot connect to rhel-dell I can ping in both directions.

I would suggest disabling iptables to make sure that it isn't interfering.  *** I've seen that happen on local lab systems even when it appears that the connection should work looking at the iptables output.  The lab systems also exited with a status 25.

I assume the master is also the media server in this case?

 

*** PS - great information - might be a little easier to read if you post it as an attachment next time :)

Hi Deb,

You are a genius.

I stopped the iptables service and the backup has worked!

I'll know where to come next time I have an issue.

Thank you very much!

Sorry for the formatting above, hopefully this is a bit clearer:

I have installed the Netbackup client on a Red Hat LINUX server, but when I attempt a backup it fails to connect with the following errors:

12/07/2016 12:34:52 - Info bpbrm (pid=8316) connect failed STATUS (18) CONNECT_FAILED 12/07/2016 12:34:52 - Info bpbrm (pid=8316) status: FAILED, (44) CONNECT_TIMEOUT; system: (10036) A blocking operation is currently executing. ; FROM 0.0.0.0 TO rhel-dell 10.129.216.55 bpcd VIA pbx 12/07/2016 12:34:52 - Info bpbrm (pid=8316) status: FAILED, (44) CONNECT_TIMEOUT; system: (10036) A blocking operation is currently executing. ; FROM 0.0.0.0 TO rhel-dell 10.129.216.55 bpcd VIA vnetd 12/07/2016 12:34:52 - Info bpbrm (pid=8316) status: FAILED, (44) CONNECT_TIMEOUT; system: (10060) Connection timed out.; FROM 0.0.0.0 TO rhel-dell 10.129.216.55 bpcd 12/07/2016 12:34:52 - Error bpbrm (pid=8316) Cannot connect to rhel-dell

I can ping in both directions.

I’ve included some info below that seems to be relevant based on searching for the errors. Any ideas would be most welcome.

Thanks

Hi Deb,

Thanks for the prompt reply.

Yes the server is both a master & media server, it's also a Windows server as you've probably gathered from the output.

I'll look into disabling the iptables firewall.....

Thanks.

I'll keep my fingers crossed.  Let us know if disabling iptables (at least for a test) allows the connection to succeed.

Hi Deb,

You are a genius.

I stopped the iptables service and the backup has worked!

I'll know where to come next time I have an issue.

Thank you very much!

LOL - I have just seen it before in the labs so knew what the most likely issue was.  :)  Have a great day.
