Hi, Joseph.  I haven't tried to connect to the RIP with the
self-signed certificate because both Real servers currently shared the
same certficate/key.  I haven't explored creating different
private/public keys for this scenario yet.  However the problem is
that from the standby real server, I simply could not connect to the
VIP (by ssh)  of the lived master server.   For some unknown reasons
(to me), lo:0 interface got activated and masked the VIP on other
server.  I could only connect to it without lo:0 on the standby real
server (and without arptables).  I just would like to know if this is
something that I misconfigured somewhere in my setups or it is
something else.

Is there any other workarounds beside removing lo:0 like I did?

Please help.

Thank you very much.
