How do I make SuMa talk to clients on multple subnets?

Hi there. I have clients I am trying to add and it seems that if they are on a different subnet than my SuMa server then it is stuck at:


  • downloading necessary files…
    curl: (7) Failed connect to; Connection timed out
    curl: (7) Failed connect to; Connection timed out
    ERROR: was not downloaded
    Last login: Wed May 2 15:20:44 UTC 2018

. How do I accommodate for this? I know this seems like a general Linux question, but since my issue is within SuMa I figured I’d ask here.

That looks like a general Linux question indeed !

How did you get the bootstrap script to the client ? Is there a network connection ? Can the server ping the client ? Can the client ping the server ?
Is there a firewall inbetween ? Make sure that its configuration follows the firewall rules:

Well, the bootstrap script never made it to the client seems since I got stuck here. There is a network connection. It seems I can ssh into the client, I can’t do much else. I gave the service account permissions in the client. The client can ping the server, but not able to ssh to the server. There is a firewall active on the server as is the client side, but both seem to be open on the right ports.

Maybe a DNS issue. The server’s FQDN needs to resolve to its IP address and vice versa. Check with “dig” and “dig -x”.

By the way, that ‘’, I’m assuming that is supposed to be the FQDN of my SuMa server? Because I can’t find where I am supposed to change that.

You can’t change a SUSE Manager Server’s FQDN after installation because it would invalidate all certificates.


Maybe there is a wrong name in Admin → Manager Configuration → Bootstrap Script?
But first I think you could try to change the name directly in the bootstrap script just for testing. They are in /srv/www/htdocs/pub/bootstrap .
But also try to figure out if there is just a routing problem to the SuMa Server. If a ping or telnet [suma-server] 443 doesn’t work, everything else will also fail.
