[Gloucs] Lan configuration

[David]

  As I have mentioned to Guy and others, I have been having problems 
setting up a simple connection share between two Mandrake boxes.  The 
hardware is recognised no problem, and both boxes can ping each other.  
If I then run SSH 192.168.1.252 I get :*Port22 Network unreachable.*
 That is as far as it goes though and as a very simple newbie, I have 
run out of ideas.

 Ping shows the following  :
 PING 192.168.1.252 (192.168.1.252) from 192.168.1.253 : 56(84) bytes of

Netstat -rn came up with the following:

/etc/sysconfig/network is this:
NETWORKING=yes
FORWARD_IPV4=true
DHCP_HOSTNAME=davey@localhost.localdomain
HOSTNAME=happy
DOMAINNAME=localdomain
GATEWAY=192.168.1.1

 If this is a firewall issue, how do I go about altering it?

I would be grateful for any help
