[ale] Network problem: 'no route to host'

Your mask from the ifconfig output says that it is using an 8 bit subnet
mask...your routing table says 24 bit subnet mask.
>inet addr:1.2.3.42  Bcast:1.255.255.255  Mask:255.0.0.0
>eth0 1.2.4.0         *               255.255.255.0   U     0      0

This does not agree with your routing table. This could be potentially
causing you some problems.
