NMC - New Setup
Hello all,
Greetings for the day!!
I am doing fresh installation from NW Server, Storage Node and I got stuck in NMC. Finished installation of NMC in centos and configured with the NMC_Config script. But not able to connect my console when i am trying to access NMC from local host with https:// :9000
I able to ping nmc server from my local system, So i believe there is no issue with connectivity.
I am thinking it's due to port issue. Any suggestion?
Note: gst service started without any issue
Thnks,
Sam

Samuel.
If you need iptables up and running, you need to add some rules to get ports opened in networker server. In recent versions of Networker Security Guide are not given this rules (I don't know why, honestly). But you can see "Networker 7.5 Firewall and TCP configurations" to consider rules given there.
We don't use iptables, We delegate security to external Firewall. So, we disable iptables. I am not expert in CentOS, but for RHEL you can disable with "service iptables stop" and then use "chkconfig iptables off" to prevent iptables go up when reboot server.
Hope it helps.

Check if iptables and selinux are blocking connections

Looks like the local firewall is blocking it. From your PC try to telnet the NetWorker NMC server on port 9000.

Plz check the version of the Java runtime environment (JRE) in your PC, and make sure the firewall both in NMC server and PC can 't stop your connectivity．

Hi Samuel,
Not sure if you mentioned https by mistake or trying to access the NMC with HTTPS.
Access the NMC with HTTP not HTTPS.
http:// :9000
if you are accessing the NMC from same server : http://localhost:9000
also you can disable the local firewall in centos by using iptables off command.

Thanks Gautam. You're right. I am not able to do telnet my NMC server via 9000 port. But I didn't think as it's due to local (PC) firewall blocking. Because I able to do other NMC servers (hosted on windows- same new setup) from this PC.
Any other suggestion which may help to get closer..
Thx,
Sam

Hi Samuel,
I wanted to say that the firewall on your NetWorker Server is blocking the traffic.
you can use the following commands to disable firewall on CENTOS.
systemctl stop firewalld
systemctl disable firewalld

Perfect ledugarte Thanks lot for your help.. This works..
I fixed temporarily with "iptables -F", I heard after reboot again it will block. From your statement, I can prevent this even after reboot also.
Thanks again!
