Link XSIBackup-DC -> XSIBackup-NAS

Hi,

I would like to use XSIBackup-NAS from a XSIBackup-DC. I am trying to set up a link and after
entering the IP of the XSIBackup-NAS I get a request from the NAS to enter the password.
But after that I get the message 'You can only link to Linux and VMWare ESXi hosts'

Is there something I am doing wrong here ?

Thanks,
Thomas

Re: Link XSIBackup-DC -> XSIBackup-NAS

Use the [b][url=https://33hops.com/xsibackup-dc-full-manual-home.html#add-key]--add-key[/url][/b] action from the command line instead of using the GUI.
The complete message above should be:

You can only link to Linux and (c)VMWare (c)ESXi hosts
Response was: some text

Could you provide the response text?: that's where the information is contained.

ssh does work though on the commandline:

gives me instant login into xsibackup-nas. VM Firewall for ssh client/server is open.

The response from the gui is just "You can only... ESXi hosts ############### # Tip: ################################# #Tip: type the menu....etc

Any idea would be appreciated,
thanks,
Thomas

Re: Link XSIBackup-DC -> XSIBackup-NAS

We haven't tested [b](c)XSIBackup-NAS[/b] with [b](c)ESXi 7.0[/b], please use some older version. That doesn't mean it can't work, but most probably default OpenSSH configuration is preventing [b](c)ESXi 7.0[/b] from being able to authenticate by public key.

We don't understand what you mean by "[b]ssh does work though on the commandline[/b]", the example you are posing is misleading.

You can't login to [b](c)XSIBackup-NAS[/b] using the (c)XSIBackup-DC RSA key; by running

ssh root@134.28.70.59

You are using the default (c)ESXi host key. To use [b](c)XSIBackup-DC[/b]'s RSA key run the code below from the installation dir:

ssh -i xsibackup_id_rsa root@134.28.70.59

[b]Update:[/b]
Apart from that, you can easily exchange the key manually, just paste the [b]xsibackup_id_rsa.pub[/b] to its own line in the [b]authorized_keys[/b] file at [b](c)XSIBackup-NAS[/b], it is located in the [b]/root/.ssh/[/b] dir

Re: Link XSIBackup-DC -> XSIBackup-NAS

yes the manual exchange is working.
I only have 1 ESXi and its on V7.
I'll see how it goes and test things...

Thanks for the help,
Thomas

Re: Link XSIBackup-DC -> XSIBackup-NAS

We did a correction to our previous post, there was a typo. The key that you have to paste in the [b]authorized_keys[/b] file is the public key: [b]xsibackup_id_rsa.pub[/b]

BTW, what do you mean by V7?

I didn't even notice there was a typo... what I did worked anyway... thank you
