wireless & wired active?

hi all

i have ubuntu setup on my laptop. my primary connection is my wireless but i also have a wired connection which i would like to use to connect to a media centre box which is linux based.

i did have it setup in windows in the old days but cant seem to get it to work in linux. the old windows setup was to give the wired connection a static ip, add a user and a share folder, and then give the media centre box a user name and password and also a shared directory to mount. also had to tell it what ip to look at

i used to be able to ping the box but cant no more which suggests that my wired connection isnt active - i dont know how to make it active...i have tried going through the network connections but seem to activate as i cant get it to ping the other box.... is it possible to have it active at the same time as the wireless if so how?

i have setup a share folder under /home/media/ with a NFS share

my ifconfig -a

my media box is

ip: 198.168.0.3
sub: 255.255.255.0
broadcast: 198.168.0.255
gateway & DNS: 198.168.0.2

can anyone help?

I do not Ubuntu setup but if you are wanting the media box to connect to the net this is probably what you want to do. Sorry if it gets to technical.

First setup eth1 as you more than likely have now.
On eth0 you only need to set an IP and netmask. No gateway needed.
Now going to say http://easyfwgen.morizot.net/gen/ and and answer the questions to setup a gateway/firewall.
Copy the script it shows at the end and save to a file in say /etc and call it firewall.sh
Now make the /etc/firewall.sh executable. ' /sbin/chmod +x /etc/firewall.sh '
Bring up both nics and make sure internet is working.
Next run the script from /etc directory like this as root. ' ./firewall.sh '
Now see if the media device box does what is needed.
