Cipher Algorithms: des3_ede= 3des_CBC??

[StraightL]

I am testing openswan 3.01 on Debian.

ERROR:
Jul 8 16:16:09 Debian pluto[9381]: "net-to-net" #3: ERROR: netlink response for Add SA esp.af7ed6f@192.168.44.10 included errno 38: Function not implemented


I guess it is due to incompatible algorithm.
Because openswan is aksing for
"IKE algorithm newest: 3DES_CBC_192-MD5-MODP1536"

but my box only support:

Debian:/lib/modules/2.6.11.7pcnet/kernel/crypto# modinfo des
filename: /lib/modules/2.6.11.7pcnet/kernel/crypto/des.ko
alias: des3_ede
license: GPL
description: DES & Triple DES EDE Cipher Algorithms
vermagic: 2.6.11.7pcnet PENTIUM4 gcc-3.3

So the question is des3_ede= 3des_CBC??


Thanks!
