[strongSwan] RSA-encr authentication IKEv1 - no RSA private key found for

[Alex Zetaeffesse]

Hi there,

I'm trying to build a tunnel with key-auth between strongswan and a Cisco
router.
Phase 1 doesn't complete successfully because StrongSwan complains that it
cannot find a key for the the other side.

May 17 05:52:10 ubuntu charon: 05[IKE] no RSA private key found for
'192.168.72.4'

however the key is loaded fine when I reload ipsec

May 17 05:42:12 ubuntu charon: 00[CFG]   loaded RSA private key from
'/etc/ipsec.d/private/ubuntu_prv.key'

and ipsec.secrets looks as follows

192.168.72.144 : RSA /etc/ipsec.d/private/ubuntu_prv.key

root at ubuntu:/etc# ls -la /etc/ipsec.secrets
/etc/ipsec.d/private/ubuntu_prv.key
-r-------- 1 root root 1679 May 15 03:02 /etc/ipsec.d/private/ubuntu_prv.key
-rw------- 1 root root  379 May 17 05:42 /etc/ipsec.secrets

root at ubuntu:~/temp# head -2 /etc/ipsec.d/private/ubuntu_prv.key
-----BEGIN RSA PRIVATE KEY-----
MIIEpAIBAAKCAQEAx70hAWwWg6LRdqXkdInmShazUHsrHHbbaPc6jUtlR2n/zngv
(it's not encrypted)

Where am I doing wrong?

Thanks in advance, Alex
