i had a previously working configuration with the config files used in a previous question

However, i've changed this now to the following configuration using server mode, everything on the logs seem fine, however the client doesn't create any tun interface, so i don't have anything to connect to, presumably, i need to add or push some route commands, but i don't have any idea at this point what i need to do. I am posting all my relevant configuration files

server.conf:

dev tun
server 10.8.117.0 255.255.255.0
ifconfig-pool-persist ipp.txt
tls-server
dh /home/lurscher/keys/dh1024.pem
ca /home/lurscher/keys/ca.crt
cert /home/lurscher/keys/vpnCh8TestServer.crt
key /home/lurscher/keys/vpnCh8TestServer.key
status openvpn-status.log
log         openvpn.log
comp-lzo
verb 3

and client.conf:

dev tun
remote my.server.com
tls-client
ca /home/chuckq/keys/ca.crt
cert /home/chuckq/keys/vpnCh8TestClient.crt
key /home/chuckq/keys/vpnCh8TestClient.key
ns-cert-type server
; port 1194
; user nobody
; group nogroup
status openvpn-status.log
log         openvpn.log
comp-lzo
verb 3

the server ifconfig shows a tun device:

tun0      Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  
          inet addr:10.8.117.1  P-t-P:10.8.117.2  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:100 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

However the client ifconfig does not show any tun interface!

$ ifconfig tun0
tun0      Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
