[Openswan Users] no RSA public key

[Salvatore]

Hi, I have a problemu with openswan-2.4.7 and site-to-site connection, my 
ipsec.conf is:

config setup
interfaces="ipsec0=eth0"
conn %default
esp=3des-md5
rekey=no
conn afra-aquila
auto=start
authby=rsasig
pfs=yes
#sede left
left=82.104.xxx.xxx
leftsubnet=172.16.0.0/24
leftnexthop=82.104.xxx.xxy
# RSA 2192 bits   host122-bla.it   Mon Jun 25 16:41:02 2007
leftrsasigkey=0sAQOSd...
#sede right
right=79.5.yyy.yyy
rightsubnet=10.0.0.0/24
rightnexthop=79.5.yyy.yyx
# RSA 2192 bits   host90bla.it   Mon Jun 25 16:42:41 2007
rightrsasigkey=0sAQOZ74bR....

...in log file I have (on both sides):

I have generate keys in this mode:

#ipsec newhostkey --hostname host90bla.it --output /etc/ipsec.secrets

Thanks.
