necessary to encrypt data between 2 hosts?

[fraksken]

Hey,

My LDAP VM needs to supply information to another machine. For some reason I can't get the SSL to work.
Is it a great security risk if these 2 hosts, which are on the same node, transfer data without encryption?
Does Proxmox make a direct connection, or does the data first go to the router and then back?

Thanks

when in doubt, run wireshark or tcpdump on that network and see for yourself. securing layer 2 (where the switches and bridges are) is a broad topic.

in this case, i would make a bridge just for those two nodes to communicate and not let anything else on it. its the virtual equivalent of a cross cable.
