this step defines the actual connection. when ipsec is started, it examines the ipsec.conf file, creates a lists of connections which can be left in one of several states (ignored, added, upped..)I want to know the difference between these 3 things. 1)adding connection information to /etc/ipsec.conf
this step adds a connection which (was already described in ipsec.conf and either a) marked as ignored or b)was added but deleted afterwards ) to the list of connections available to the kernel2)ipsec auto --add conname
this step tries to activate (& use) the connection which was previously upped.3)ipsec auto --up connection
