Hello all,

I am new in Linux ,
I am working on IPSEC tunnels with Cisco Routers successfully.
I am trying to get certificates from Ubunto CA server ,
I installed Ubunto 12.04 with Kernel 3 5 0 40 and tried to install CA server according to the following link :

After that I am trying to receive the Certificate from the Ubunto sending request from cisco router but seems it fails before starting .

Can anyone send an example for "ubunto CA server installation" ?
