Hi,
after a vacation, I upgraded sid on my laptop. After pulling in 3 week's
worth of upgrades, I lost ethernet connectivity, and for the life of me
can't figure out what went wrong. Nothing changed in the network's
configuration.
I have a cardbus ethernet card in my laptop. It is connected to a little
hub. The hub's LEDs light up when it is plugged in. The gateway,
192.168.1.1, is connected to a pppoe internet link and is the only other
machine currently on the network. The laptop's eth0 is ifup'ped and
ifdown'ed by hotplug via a mapping stanza in /etc/networking/interfaces:
-------------------
mapping hotplug
script /bin/grep
map eth0
auto lo
iface lo inet loopback
iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
-------------------
The only strange thing I notice is that upon hotplug startup I get:
-------------------
Starting hotplug subsystem: input** can't synthesize input events -
/proc/bus/input/devices missing
pci** can't synthesize pci hotplug events
-------------------
This sure looks suspicious to me, since cardbus is managed as a pci
device AFAIK. But the interface seems to come up normally, the modules
are found, the driver loads. Also, the LEDs on the card connector light
up.
Since the upgrade, I can't connect to the gateway anymore (neither using
the name nor the IP): ssh tells me "no route to host", ping returns
nothing.
route -n on the laptop, 192.168.1.2, gives me
-------------------
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
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
-------------------
To me everything looks ok, I'd appreciate any hints.
Regards, Mario
