Hi,
Have a look to
http://vouters.dyndns.org/tima/Linux-Shrew-VPN-Client-Setting_an_Intranet_VPN_with_Windows_Seven.html
and its '#ipsec auto --status' command. Do consider how Philippe_PSK and
FIXED_RIGHT_IP conns are retrieved.
On your side and even if not connected to the Cisco remote peer, the
'#ipsec auto --status' should show up centos6-asa-net-net.
Yours truly,
Philippe Vouters (Fontainebleau/France)
