Subject: no IKE config found for ..., sending NO_PROPOSAL_CHOSEN
Hello Everyone,
I have two machines one Ubunto 12.0 with strongSwan 4.5.2.1 and one a Openwrt router running strongswan 5.0.4.1.
I am configuring a simple host-host topology with secret key ( password). I ran >>ipsec start --nofork on ubuntu machine and >>ipsec up conn on Openwrt router .You can see below that I get error of No_PROPOSAL_CHOSEN.
Here are all my config files:
Here is the ipsec.conf for client side (openwrt):
version 2
config setup
charondebug = "ike 2,knl 2"
conn Ubuntu
ikelifetime=60m
keylife=20m
rekeymargin=3m
keyingtries=1
keyexchange=ikev2
left=192.168.1.55
right=192.168.1.209
authby=secret
auto=add
leftid="@lmu55"
esp=3des-md5,3des-sha1
ike=3des-md5-modp1536,3des-sha-modp1536,3des-md5-modp1024,3des-sha-modp1024
rightid="@lmu209"
type=tunnel
****No matter what I chose for ike and esp I get the error.I even left them out from the file but still getting error
Here is the ipsec.conf from server side: (Ubuntu)
:config setup
plutodebug=all
charonstart=yes
plutostart=no
conn %default
keyingtries=1
keyexchange=ikev2
left=192.18.1.209
leftid=@lmu209
authby=secret
mobike=no
pfs=no
# Add connections here.
# Sample VPN connections
conn desktop
right=192.168.1.55
rightid=@lmu55
type=tunnel
auto=add
here is the strongswan.conf in server side: ( Ubuntu):
~# strongswan.conf - strongSwan configuration file
charon {
# number of worker threads in charon
threads = 16
# send strongswan vendor ID?
# send_vendor_id = yes
plugins {
sql {
# loglevel to log into sql database
loglevel = 2
# URI to the database
# database = sqlite:///path/to/file.db
# database = mysql://user:password@localhost/database
}
}
# ...
}
pluto {
# load = sha1 sha2 md5 aes des hmac gmp random kernel-netlink
}
libstrongswan {
# set to no, the DH exponent size is optimized
dh_exponent_ansi_x9_42 = no
}

And here is the output of the ipsec start:
