A compatible version of Cockpit is not installed on XXX

[Daniel Hilst]

Hey everybody

I'm trying to setup dashboard between some machines. When I try to add a
machine to the dashboard it gives me *A compatible version of Cockpit is
not installed on <ADDRESS>. *I'm trying to figure out what is happening, I
tracked the code up here:
https://github.com/cockpit-project/cockpit/blob/master/pkg/lib/machine-dialo...

I fireup a tcpdump at target and didn't see any noise from the source, so
my guess is that something is going wrong on the source side. Also I tried
to connect from the target to source and it worked like a charm.

How *cockpit.channel(...)* works. They are a websocket based connection,
how can I troubleshoot this? Is there any command line to test cockpit
machines connection?

I'm using cockpit from centos7 repositories, version 176. cockpit-dashboard
and bridge is installed on both ends and also started. I can connect to
cockpit in the target and even add source in its dashboard, is only source
-> target that isn't working.

Any help would be appreciated!

Regards,

[Daniel Hilst]

Okay, I got something but I need to help to interpret this, I got the WS
messages:

[image: image.png]

{"payload":"echo","host":"192.168.123.3","command":"open","channel":"1:2!18","flow-control":true,"group":"cockpit1:localhost/dashboard"}
1:2!18 x 8
 {"command":"close","channel":"1:2!18","problem":"not-supported"}

This *cockpit1/localhost* seems strange to me :/

This is strange.

I'd suggest you look at the journal logs and see if cockpit-ssh or
cockpit-bridge is posting any explanatory messages.

It may be that the credentials you're using to connect to the other host
don't allow cockpit-bridge to be executed (for some strange reason).

Cheers,

Stef

There is no cockpit-ssh running! Thank you so much Stef! I'll try to find
out why is not running,

Thanks again Stef, my libssh was corrupted, this is verifiable by `rpm -qV
libssh`, no output means okay. I just reinstalled with yum reinstall and
now everything works like a charm!

Cheers
