enabling ipsec support in kernel

[mummaneni]

Hi everybody,
I am using FC1 with kernel version 2.4.22-1.2149.nptl

I am trying configuring VPNs through IPSec.

I am getting the following error while giving the ipsec verify command

bash]# ipsec veriy
Checking for IPsec support in kernel [FAILED]

bash]#/etc/init.d/ipsec start
Starting IPsec: Starting Openswan IPsec 2.1.5...
insmod: ipsec: no module by that name found
modprobe: Can't locate module af_key
modprobe: kernel appears to lack KLIPS
Can't locate module ipsec
[FAILED]


I have tried the kernel compilation, But i didn't find any option regarding ipsec
(GRE, l2tp are there).

Is ipsec support there in this kernel or not.

Please help me in enabling ipsec module support.

Thanks inadvance,
Mummaneni.

I don't know what was compiled into FC1, but KLIPS is in FC3,4,5 by default.

You enable KLIPS/ipsec you need to "make xconfig" and select "networking" on the left pane. On the right pane select "networking support/networking options".

Under this you should see &select
+ IPSEC user configuration interface
+ PF_KEY Sockets
+ IP:AH transformation
+ IP:ESP transformation
+ IP:IPComp transformation
+ IP:Tunnel transformation
I doubt it's necessary but you should check "The IPv6 Protocol" and all the minor items under it.
