What IPs are connecting to my Celerra NAS?

for cifs you can look at CIFS server properties in the MMC, session area.

Hi Slivesey,

For display the active TCP connection, you can use the command of server_netstat.

use server_tcpdump and capture SMB1/SMB2 traffic.

Hi Jeffey,

We tried using the command on EMC "server_netstat server_2", but this give us IP addresses for the data mover, but does not give us the list of windows servers which are connected to the NAS.

Do we have any other option, any help would be appreciated.

Did you try the list of CIFS sessions via MMC or server_cifs –o audit ?

Yes I do have the list of CIFS sessions from MMC but gives you information about File, CIFS Servername and Interface IP, but this does not give you detail as to where the share is monuted on which windows server and which servers are connecting to the NAS share.

I will see the output from the above command which you mentioned.

Thank you will try to capture SMB1/SMB2 traffic.

Well – some information – like where on the CIFS client the share is mounted isnt available on the CIFS server

Hi James,

For checking active NFS connection session, you are able to use the command of server_netstat in Celerra. Because the client are directly connected to Data Mover via NFS protocol.

For checking active CIFS connection session, you can only check it in windows server. As I know, we can't observe the active CIFS connection session via command in Celerra. 

Sure you can – you point MMC computer management to the CIFS server of the VNX/Celerra and the list all the CIFS session that the Celerra has.

server_cifs audit should be able to do the same

Hey Jeffey,

That is what we are trying to figure out on which windows servers the CIFS shares are mounted or rather which windows servers are using the shares which are on the NAS. Until which we cannot find the list of sessions which are open towards the Celerra NAS.

Awesome I could access that from MMC and could find the open sessions towards to the Celerra NAS. But only if I do have access to the CIFS Shares.

That's how it goes.

You can also use MMC to manage shares
