Package: debian-installer
Version: 20090123lenny1
hi,
the debian-installer seems to assume that the network is usable as soon
as the link comes up, which may not be the case if the 802.1d spanning
tree protocol is in use, in which case it can be up to ~30 seconds
before the switch port will forward ethernet frames.
i've noticed that trying to preseed a network install on a machine
attached to an STP-enabled switch usually fails since as soon as the
network link is up, d-i attempts to perform a reverse DNS lookup and
fetch the preseed.cfg file via HTTP, both of which timeout and fail
before the switch port the machine is attached to enters the forwarding
state.
a nice strategy to detect if the network is usable might be to send ARP
requests for the default gateway's IP address and consider the network
"up" only after the default gateway is reachable. it looks like there
is a busybox version of the arping utility that could help accomplish
this.
