[Openswan Users] nss DH woes

[Richard Pickett]

Curu,

I'm not using sonic wall in my config as Kevin is (the other user reporting
the same problem). The client side is shrewsoft, and it may be part of the
problem, but it's odd that the nss on the server is throwing an error and
causing pluto to die and restart, the client should never be able to cause
that.

Can you send me your config(s) and how you created your keys (did you create
them in nss or import them?)

It would help a lot, and I really appreciate you taking the time to help!
