Nutanix Move - Port Requirements - More detailed info required than what is public

Hello Team,

I am working on a project where Nutanix Move will be highly leveraged for migration from Hyper-V, VMware to AHV Cluster. 

I know the ports that are required to be opened between diff source and destination, however customer is asking for more details as in what is the usage of the ports. 

Do we have any docs with detailed explanation on port usage? 

For example usage of ports 2049 (I know its for udp nfs but little more details :))

Also some of the follow up questions:

  1. Is it mandatory to open port 80 (http) for Nutanix Move to work? Cause in this environment only secured communication is allowed 443 (https)
  2. Port 22 used for SSH to Linux VMs - Does it use asymmetric or symmetric encryption?

Please advice. Thank you in advance!

Hi @Ravi Kumar Please take a look at the following document.  You should be able to find your answers in there.

@Michael.Manuele Thank you, I did go through this document but my customer needs some more details that what is mentioned in the document. Like the actual usage of port. 

Also, could you help with below queries:

  1. Is it mandatory to open port 80 (http) for Nutanix Move to work? Cause in this environment only secured communication is allowed 443 (https)
  2. Port 22 used for SSH to Linux VMs - Does it use asymmetric or symmetric encryption?

@Ravi Kumar I guess I am a little confused when you say actual port usage.  In that document that I referenced above their are several tables depending on what your source/destination is with a list of ports/protocols and description.  Is the description not enough for your customer? 

In your example you reference 2049 is NFS.  What more do you need?  NFS is used for copying/storing data and move is designed to copy data from one source and store it at the destination.  If they require more details on NFS I am pretty sure they can google it and read the RFC.  I am happy to answer more specific questions, but not sure what you need.  

Query answers:

  1. Currently Move has never been tested with port 80 blocked.  If it is blocked preparation may not work and move agent installation on Hyper-V host may fail.
  2. I don’t think that there's a choice between "symmetric" and "asymmetric" in SSH. Both symmetric and asymmetric encryption is used in SSH, but for specific tasks. I might be wrong here.
