strongswan-ikev1 4.4.0-2ubuntu1 (ia64 binary) in ubuntu maverick

 StrongSwan is an IPsec-based VPN solution for the Linux kernel. It uses the
 native IPsec stack and runs on any recent 2.6 kernel (no patching required).
 It supports both IKEv1 and the newer IKEv2 protocols.
 .
 Pluto is an IPsec IKEv1 daemon. It was inherited from the FreeS/WAN
 project, but provides improved X.509 certificate support and other features.
 .
 Pluto can run in parallel with charon, the newer IKEv2 daemon.
