IPSEC: just AH, no ESP

[Roger Grosswiler]

	Ciao,

i configured an ipsec-tunnel between 2 machines, using
system-config-network (i think it uses openswan) 

i configured it using psk, both have the same, but i just get
AH-Headers, no ESP. 

Is there some kind of checklist for this? i would like to get ESP, not
AH.

Roger
