If you cannot connect at all between the K2000 appliance and the RSA, there are two factors that can cause this.
Name resolution is incorrect.
The other other possible issue is that in the Mangaged Linked Appliance page there is a check box for SSL. If SSL is not being used, then checking this box will case the linking to fail. It is recommended to link the K2000 and the RSA and confirm communication before enabling SSL.
NOTE: Even though it is possible to navigate from the K2000 appliance webpage to the RSA webpage using single sign on, it does not mean that files can be synced between the two appliances. The linking process (single sign on) uses port 80 while the syncing of files uses Secure Shell (SSH port 22).
SSH is sensitive about the name of the computers the files are coming from and going to. Matching the name is part of the security verification. If the name of the appliance does not match the name in the Managed Linked Appliance page or visa versa, the sync will fail.
There are several errors that could result if the names are not setup correctly. looking at the K2000 logs will reveal possible entries like the ones listed below.
In the console the log in question is Server Processor Task error log. "Host Key verification failed"generally means the a naming mismatch. In the case of the example, error 255 is given. Error 12 may also be exhibited.
