Typical RCCMD installation Problems

During testing, everything worked very well, but now.

Check the license on your ESXi host. If you have used an evaluation key for the ESXi host when setting it up, you may have configured some commercial functions. If you then imported the free key, strange error messages may suddenly appear or the host may no longer shut down.

Also check whether you have entered the correct key into the RCCMD. Basically, the RCCMD appliance is equipped with an evaluation key that can be changed at any time via the web interface. When the evaluation period has expired, RCCMD will stop the service. If you enter an incorrect or invalid key, the evaluation phase is automatically activated.

Sometimes one RCCMD runs, then the other.

This always happens if you have accidentally entered RCCMD keys several times. In this case, when the network starts, the first RCCMD that starts with an affected key will claim it for itself. Subsequent RCCMD clients, however, will stop again with a corresponding log entry “License fraud <IP address>.

Typical network problems, e.g.,

vLAN is in use:

Even if both hosts are on the same switch, because the ports are separated via vLAN, they must be seen as two separate networks.

Port separation and/or missing routing:

This configuration is quite common when servers are in different network segments and e.g., an uplink line to a neutral third network segment with an internet connection exists. The router requires special routing entries in order to be able to mediate between the networks. Among other things, you can also set here that the RCCMD appliance can reach only the hosts.

Firewall settings and intrusion detection

A firewall or intelligent intrusion detection detects that RCCMD has no internal port release and rejects communication. As a consequence, RCCMD cannot reach host 2. Very large networks also use a multi-level or modular firewall concept. Check whether the firewall settings have to be adjusted. Smaller systems, on the other hand, can get these problems if e.g., a local firewall and an additional Internet security software package are in use simultaneously.
