[Openswan Users] method to determine if a tunnel is established ?

[Laurent LAVAUD]

hello,
 
i would like to know which is the best method to know if a vpn is up or no ?
 
actually i have a script which check every X seconds output of the "whack --status" command and search for an IPSEC SA established corresponding to the tunnel name.
 
the problem is that i have a lot of tunnel and the output of the command is about 15000 lines, and it takes lots of cpu in order to analyze it...
 
a "whack --status --name tunnel_name" could be a good thing but dont exist...
 
is there any quick method  to determine if a specified tunnel is up or not ?
 
thx.
