I am running FC5. It works fine.

ISAKMP (or IKE) is the key exchange mechanism for the VPN.
It seems it is not installed on my system. Please read the following:

[Nissanka@c83-250-99-43 ~]$ su root
Password:
[root@c83-250-99-43 Nissanka]# find / -name IKE
[root@c83-250-99-43 Nissanka]#



[root@c83-250-99-43 Nissanka]# find / -name ike
[root@c83-250-99-43 Nissanka]#


[root@c83-250-99-43 Nissanka]# find / -name isakmp
[root@c83-250-99-43 Nissanka]#

[root@c83-250-99-43 Nissanka]# find / -name isakmpd.policy
[root@c83-250-99-43 Nissanka]#

[root@c83-250-99-43 Nissanka]# find / -name isakmpd
[root@c83-250-99-43 Nissanka]#

I would like to hear from you all.



However, 'sysctl.conf' file is on the 'etc' folder.

right, so install it if you want to use it. more likely you'd use racoon afaik, which is part of ipsec-tools.

Thanks acid kewpie for the reply. You will find the stuff on the following page. There are so many files. Could you please advice me on this? I just want to know the correct file for me.

http://ipsec-tools.sourceforge.net/

ipsec-tools is normally part of the fedora base install. if not, just get it through yum
