What TCP/IP Ports are needed

What TCP/IP Ports are needed

From Networker Client to Networker Server?
7937 and 7938?

From Networker Storage Node to Networker Server?

Are this ports corect?

Thanks for your help

RE: What TCP/IP Ports are needed

Since NW 7.3.0:
  - the NW client SW (nsrexecd) needs 4 ports
  - the NW storage node needs 1 port per nsrmmd (per device)
    plus 1 temporary one for a 'helper' (if the save set continues on another media)
    +1 port for each nslcpd process
  - the NW server needs:
      nsrd          1
      nsrmmdbd      1
      nsrindexd     1
      nsrjobd       2
      nsrmmgd       1
Do not forget:
  - these values are 'function-specific'. For a SN and the server you must add the ports appropriately.
  - Ports 7937 and 7938 are fixed - you can not move them!

You will find procedures how to specify the port ranges in Appendic B of the current NW Admin Guide.

RE: What TCP/IP Ports are needed

Hi 605

Thanks for your help.

1 Question to make it clear.

A Client needs 4 Ports 7937 and 7938 Pus 2 free Chosen.
A Storage Node with 4 LTO3 Drives need 12 Port (4 nsrexecd 2x4 for the Drives) 7937 and 7938 Plus 8 free chosen.
A Server with 8 LTO3 and 4 Librarys need 24 Ports.

I configure the Ports over the Console (Configuration>Local Host> right click > Configure Port Ranges.
I can do that with the networker server but if i couse a client or Dedicated Storage node then i got this message "Unabele to connect to Server: Failed to contact using UDP Ping" what is wrong?


RE: What TCP/IP Ports are needed

1 more question

If i have 10 Storage Node. I need 12 Ports for a Storage Node (see example above)
Can i use the same 12 Ports for alle 10 Storage Node (only 12 Ports are open at the Firewall?


RE: What TCP/IP Ports are needed

The best way to set the porst on clients and SN is :
nsrports -S 7937-7949 in your 12 Port example.

Yes you can use the same ports for all Storagenodes.

RE: What TCP/IP Ports are needed


Your calculation for the server is wrong. You will need:
  -  4 ports  for nsrexecd
  - 16 ports  for (2x8) for the devices
  -  4 ports  1 for each nsrlcpd
  -  1 port   for nsrmmgd
  -  1 port   for nsrd
  -  1 port   for nsrmmdbd
  -  1 port   for nsrindexd
  -  2 ports  for nsrjobd
That makes 30 service ports.
With respect to your problem "Unable to connect to server: Failed to contact using UDP ping." you will find the following hit in the 7.4 Release Notes:

1. Open the NetWorker Management Console window and select Setup> Setup System Options.
2. Ensure that RPC ping using UDP when connecting to NetWorker is unchecked.
Yes, you can use the same ports for all SNs.
