[Ipsec-tools-devel] too many proposals bug

[Bernhard S. <su...@an...>]

Helo,

We want to connect a Lancom VPN Router (Lancom 1811) to a Linux/racoon IPse=
c implementation. We have add the ipsec connection with the lancom wizard. =
The lancom wizard add a list of 8 proposals to the connection, like that:


remote ... {
...

        proposal {
                encryption_algorithm 3des;
                hash_algorithm md5;
                authentication_method pre_shared_key ;
                dh_group modp1024 ;
        }
        proposal {
                encryption_algorithm 3des;
                hash_algorithm sha1;
                authentication_method pre_shared_key ;
                dh_group modp1024 ;
        }

        proposal {
                encryption_algorithm aes;
                hash_algorithm md5;
                authentication_method pre_shared_key ;
                dh_group modp1024 ;
        }

        proposal {
                encryption_algorithm aes;
                hash_algorithm sha1;
                authentication_method pre_shared_key ;
                dh_group modp1024 ;
        }

        proposal {
                encryption_algorithm blowfish;
                hash_algorithm md5;
                authentication_method pre_shared_key ;
                dh_group modp1024 ;
        }

        proposal {
                encryption_algorithm blowfish;
                hash_algorithm sha1;
                authentication_method pre_shared_key ;
                dh_group modp1024 ;
        }

....
}

the problem is, that racoon can not connect and the message:=20
  ERROR: unknown Informational exchange received.

if i delete 3 proposals and i have only 5 proposals in, racoon still throws=
 this message but after a few moments (and sometimes faster) the connection=
 is initialized.=20

look like a silly bug, of lancom ipsec implementation, or of racoon.=20

greets
Bernhard
