What gets logged to /var/webmin/miniserv.error on the remote system when you get those "invalid RPC login" messages on the master system?

Master system:

thank you

Those all look harmless.

What about /var/webmin/miniserv.log ?

I don't know if it's related but I also see the following:
In Cluster> Cluster Shell Commands I select a group in "Run on servers".
When I execute my command it will execute well on all the members of the group BUT also on the elements having the same ip not present in the group.

I also note that the connection fails while the machine is easily accessible

[Jamie Cameron]

I think I see the problem - do you have the master system configured to login to the remote system as root, or some less-privileged user?

[glillette]

do you have the master system configured to login to the remote system as root

yes

[Jamie Cameron]

Oh .. I just realized that you have two servers configured with the same IP, which will confuse Webmin's RPC functionality, which causes the status to be shown wrong. This is a bug which we'll fix in the next release.

[glillette]

Thank you very much it will change my life

[glillette]

Hello,

I think the problem is not solved in the last version

image 1:
I have two configurations on the same IP
- An admin account
- A user account

When I click on the link I can connect.
When I edit the configuration (image 2 and 3), I have an identification problem (image 3).

[Jamie Cameron]

This issue is that remote RPC calls made by Webmin only work when connecting as the root user. That's why you get the "Invalid RPC login" error.

[glillette]

ha ok thank you
