[Sugar-devel] Error testing collaboration using 2 Oracle virtual machines

[James Cameron]

Thanks.

Without the Collaboration Server configured, Sugar will use link-local
Salut.  This is a normal configuration, and is the default.  It does
not require internet.  When using VMs, they must be on the same network.

With the Collaboration Server configured, Sugar will use Jabber via
Gabble.  This is a normal configuration, but is not the default.  It
does require internet, or a Jabber server on a local network.  When
using VMs, they may be on different networks.

Both of these normal configurations should be tested when porting,
thanks.  Most of my testing is link-local only.

We have a Jabber server jabber.sugarlabs.org for testing.

Is the "Protocol 'jabber' not found on CM 'gabble'" traceback
reproducible?

I don't know what you mean by "able to see the buddy icon".  In the
context of the thread, I'm confused.
