routing question

[Douglas Frank <frank@xxxxxxxxxxx>]

I'm unable to reach local networks from the new fc3 box, that I've never 
had trouble with using other unixes (or Slackware for that matter). 
It's been my experience that simply kicking off routed or gated was all 
it took to make the world accessible.  FC3 is different!

We have several networks here at work and my question is, how do I set 
up the routing table to reach them?  Example:

16.140.160/24  <-- fc3 box is on this one
16.47.32/24
16.32.176/24
..several others..

Here's the output of route(8):

Kernel IP routing table
Destination  Gateway        Genmask       Flags Metric Ref Use Iface
16.140.128.0 16.140.128.238 255.255.255.0 UG    0      0     0 eth0
16.140.128.0 0.0.0.0        255.255.255.0 U     0      0     0 eth0
169.254.0.0  0.0.0.0        255.255.0.0   U     0      0     0 eth0
0.0.0.0      16.140.128.238 0.0.0.0       UG    0      0     0 eth0

eth0 is 16.140.128.238

I can reach anything on the home network, 16.140.128, but nothing on any 
of the others.  What have I screwed up/left out?

thanks
