Hello dcampregher, 

DP uses the default SSH port configured in the IS to try to connect to the client. In my investigation, is not possible to tell DP what port use, but you can configure this on OS level. I found this forum that could help you:

Hello dcampregher, 

In DP 10, when you try to add any server to the cell, you have to specify the secure communication. Please use this command: 

omnicc -secure_comm -configure_for_is Hostname

Then retry the import. 

I hope this helps,

Worked, now the IS is imported in the CELL.

But now when i try to upgrade one Disk Agent version 10.00 the GUI prompt to enter the user and password...

 

This behavior also was changed in the version 10 ? Because in 9 and ealiers the upgrade was directly from the IS.

Hi, 

You need to enter the user and password with admin rights in this server to install the software. 

This is a normal behavior.

Even if the version 10.00 is already installed ? It just na upgrade.

So if is necessary, this server have the SSH port changed to 2227 and the root can't login directly.

Is there a solution for this case ?

Hello, 

If the installation process connects to the client the connection is fine. 

Now, you have to specify a user that can install the software. Even if is an upgrade you need a user with this rights. You only have to type it. 

When you use the user with permissions to install the process should work properly. 

If the issue persists please copy the messages generated for the process and send me this. (Remember to change the names of the servers for privacy.)

Hello

Please check SSH configuration, if this right DP shouldn't ask for root password.

Client installation procedure (push installation to Linux and UNIX clients)
Linux clients used to take rsh and rexec on Installation Servers (IS) to push packages to be locally
installed on clients (if not already configured to SSH). From Data Protector 10.00, Data Protector is
using SSH as the default mechanism to send and install software on new clients. If SSH Keys are not
pre-configured between the IS and the clients, then a password will be prompted for on a per-client
basis. If you use password-less SSH make sure the omnirc-variable “OB2_SSH_ENABLED” is set to 1
on the IS.
Benefit: SSH is a much more secure protocol when compared to rsh and rexec, which both send and
receive data in an unencrypted format. SSH sends data encrypted and is widely regarded as one of
the most secure protocols within the network. Another inherent benefit is that mutual exchange
certificates (public keys) between a Cell Manager and client will happen over this secure SSH channel.

Best Regards

Hi Andres!

So is not necessary to create the SSH Trust relationship  between servers, OK ?

If the SSH port on the server ( DIsk Agent ) has been changed from 22 to 2227 ( for example ), how can instruct the IS to use another port instead the default SSH 22 ?
