Hi all,
I am having trouble with dhcp3-client. First the trouble, then why I
think
it is dhcp3-client.
I: When I try to start the network I get this error:
----------------------------------------------------------------------------
# /etc/init.d/networking start
Configuring network interfaces...Internet Systems Consortium DHCP Client
V3.0.4

Can't allocate interface etlease {
interface .
Failed to bring up eth0.
done.
----------------------------------------------------------------------------
II: This also occurs if I just try to "ifup" the interface:
----------------------------------------------------------------------------
# ifup eth0

----------------------------------------------------------------------------
III. Running dhclient (from dhcp3-client) (on a preconfigured wireless
device)
does work:
----------------------------------------------------------------------------
# dhclient eth0
There is already a pid file /var/run/dhclient.pid with pid 2141

IV. I believe the culprit is dhcp3-client because using alternative dhcp
clients gives different (successful) results:
----------------------------------------------------------------------------
with dhcpcd instead of dhcp3-client
--------------------------------
# /etc/init.d/networking start
Configuring network interfaces...dhcpcd.exe: interface eth0 has been

Why does directly running "dhclient eth0" from dhcp3-client work
(marked
with a "III" above), while using "ifup eth0" doesn't work ("II")? It almost
appears as though ifup is pass garbled arguments to dhclient, but I don't
know enough to figure out more.
My /etc/network/interfaces:
...................
auto lo
auto eth0
allow-hotplug eth1
# The loopback network interface
iface lo inet loopback
# eth0 is wireless
iface eth0 inet dhcp
wireless-mode managed
wireless-essid any
wireless-key off
# eth1 is wired
iface eth1 inet dhcp
...................
Thanks for your help!
