Hi friends,
Sorry for asking a trivial question to all of you.. but i am really stuck.

Please reply if you have any idea.
I tried to search on the Mailing archieves, and got that this could be a version problem, but still I am not sure how to solve it.
Please help

I got into this problem, while trying to Eshtablish SA in openswan.
PS: I am installing on Red-Hat Linux-9.0,
                                        Kernel 2.4.20-30.9.

I ran:-->

ipsec spi --af inet --edst 10.232.40.40 --spi 0x123 \
--proto esp --esp 3des-md5-96 \
--authkey 0s+aadddeeeefffff2 --enckey 0s+aadddeeeefffff2 

And Got this, after switching Debug option ON:--> 


 ipsec spi --debug `cat /home/in1064c/spidata`
