How to know the VSphere Server thrue ESX ?

[OlivierTremolie]

Hi all !

I've got an ESX 4 server. I can login in with Putty but the web server is not configured.

The ESX seem to be attached to an VSphere server.

Is it possible, thrue a putty connexion, to know the name or IP adress of the BSphere Server ?

There is no easy way to find out . You may check logs under /var/log directory to check incomming TCP connections .

I assume when you say vSphere Server, you're really referring to vSphere vCenter as vSphere is just the family name comprised of 4th generation of vCenter and ESX(i) products/etc.

Anywho, yes this is possible, there are probably few ways of doing this (via logs/etc)

Here are two:

1) Using the Service Console of classic ESX

Take a look at:

/etc/opt/vmware/vpxa/vpxa.cfg

The output will be something like:

<hostIp>A.B.C.D</hostIp> # ESX Service Console IP
<serverIp>E.F.G.H</serverIp> # vCenter IP

2) Using the vSphere APIs on ESX or ESXi

If you know how to use the APIs or Managed Object Browser, there is a property that is ONLY set if the ESX(i) host is being managed by vCenter server defined by managementServerIp http://www.vmware.com/support/developer/vc-sdk/visdk400pubs/ReferenceGuide/vim.host.Summary.html

As already mentioned, you can look at the hostd or vpxa logs as well which should also have the discovery address.
