We've had some issues with our webserver ISP going under, with Paul Wouters
coming to the rescue so that we have some web presence at www.freeswan.org.
We are currently trying to correct the situation.

The command was introduced in 1.98. Do you not have a "verify" script in
/usr/local/lib/ipsec? Are you sure you have 1.98b installed correctly?

No; you'll need a VPN/Roadwarrior connection to the Cisco in question, as the
Cisco does not support Opportunistic Encryption.

True; without access to your reverse map, you can only do Initiator only OE,
and will be unable to receive incoming OE connections

It might; setting up VPNs can be a complex process, and access to the Cisco's
configuration and/or logs can be very useful as a starting point.

Left and right are arbitrary, and each represent one "side" of the connection.
An IPSec device will be represented as "left" or "right", and the protected
networks (if applicable) represented as "leftsubnet" and "rightsubnet".
