Thread: allow-hotplug eth0 not working

hello,

i'm running minimal server natty install , having trouble networking.

trying configure ethernet device fetch ip address when ethernet cable plugged in. currently, if cable plugged in when machine boots gets ip address or if manually run dhclient works. however, if boots without cable plugged in , plug in after boots, not grab ip address automatically.

currently, /etc/network/interfaces looks this:

code:

# loopback network interface  auto lo  iface lo inet loopback    # ethernet network interface  auto eth0  iface eth0 inet dhcp

i tried changing this:

code:

# loopback network interface  auto lo  iface lo inet loopback    # ethernet network interface  allow-hotplug eth0  iface eth0 inet dhcp

but isn't working. when plug in cable, nothing happens. don't see messages in syslog link coming , lights not come on on interface. (if add "auto eth0" in addition "allow-hotplug eth0", acts "allow-hotplug" isn't there.)

i'm thinking there must problem "hotplug" on system. think read natty doesn't use hotplug anymore uses udev instead. correct? chasing wrong rabbit?
