iPhone doesn't save password for Cisco IPsec VPN using racoon daemon
- by dsx
On my Debian server I had set up racoon daemon (1:0.8.0-14) for Cisco IPSec VPN using certificates for authentication. My racoon.conf is like following:
log info;
path certificate "/etc/racoon/certs";
listen {
isakmp $SERVER_IP_HERE [500];
isakmp_natt $SERVER_IP_HERE [4500];
}
timer {
natt_keepalive 10 sec;
}
remote anonymous {
lifetime time 24 hours;
proposal_check obey;
passive on;
exchange_mode aggressive,main;
my_identifier asn1dn;
peers_identifier asn1dn;
verify_identifier on;
certificate_type x509 "cert_name.crt" "key_name.key";
ca_type x509 "ca.crt";
mode_cfg on;
verify_cert on;
ike_frag on;
generate_policy on;
nat_traversal on;
dpd_delay 20;
proposal {
encryption_algorithm aes;
hash_algorithm sha1;
authentication_method xauth_rsa_server;
dh_group modp1024;
}
}
mode_cfg {
conf_source local;
auth_source system;
auth_throttle 3;
save_passwd on;
dns4 8.8.8.8;
network4 $SOME_LAN_SUBNET;
netmask4 255.255.255.0;
pool_size 128;
}
sainfo anonymous {
pfs_group 2;
lifetime time 24 hour;
encryption_algorithm aes;
authentication_algorithm hmac_sha1;
compression_algorithm deflate;
}
I'm not using PSK authentication here. Using iPhone configuration utility I had uploaded all required certificates to iPhone and set up VPN on demand. Everything works just fine except one thing: iPhone refuses to save VPN password regardless of save_passwd on; in racoon configuration file. As opposed to iPhone behaviour, Mac OS X 10.8.2 have no problems saving password. I had examined iPhone log file and found following:
racoon[151] <Notice>: >>>>> phase change status = phase 1 established
configd[50] <Notice>: IPSec Network Configuration started.
configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-ADDRESS = $SUBNET_IP_HERE.

configd[50] <Notice>: IPSec Phase2 starting.
configd[50] <Notice>: IPSec Network Configuration established.
configd[50] <Notice>: IPSec Phase1 established.
Please note IPSec Network Configuration message containing SAVE-PASSWORD = 0.. Is it a bug in racoon daemon on server, or iPhone (iOS version is 6.0.1 (10A523)) or it is me missing something? How to make iPhone remember IPSec VPN password?
