[TriLUG] some TCP utilities ignore kernel routing table?

Hi Folks,
   Just wondering if someone could shed some light on why it seems that 
some tcp utilities seem to ignore the kernel routing table.  For 
example:  (Sorry about the wrapping..)

% /sbin/route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
192.168.10.0    192.168.1.125   255.255.255.0   UG    0      0        0 eth0
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 eth0

% telnet 192.168.10.4
Trying 192.168.10.4...
telnet: Unable to connect to remote host: No route to host

Um.  Yes there is a route to the host.  Right there in the kernel 
routing table.  It says to go by way of .1.125.

What gives?  I think this also affects the cups printing manager as it 
does nothing but report no printer at the specified address/port.

Thanks,
~Brian
