Hi All,
I'm having a strange problem with a Marvell 88E8056 - 10/100/1000
Controller on a Biostar TA 770 A2+ motherboard. This is an Etch
AMD64 install, but I have added the 2.6.25-amd64 kernel as I could
not get the Marvell controller to work at all with the 2.6.18
kernel.
...
I have two NICs. The onboard Marvell and a 3Com 3c905b. The 3Com
handles dhcp and dns requests. Both are configured for statically
configured IP addresses in /etc/network/interfaces. However, the
Marvell will, after some unknown amount of time--less than 12
hours--drop its static IP address and request a dhcp address from the
3Com adapter.
...
I'm assuming this is a bug in the sky2 module, but don't know enough
about things in this area to do more than assume.
I bet it's not a driver problem but simply that you have inadvertently
started a dhclient. It picks up a lease from somewhere, but then you
restart networking which reverts the interface to a static
address. Then when the dhclient thinks the lease has expired, it goes
and gets another one.
I've seen this happen on my laptop when I've been monkeying around
with getting a connection at a new location. I'll forget that I
manually started dhclient and then some time later... maybe days, I'll
connect somewhere where I get static ip (like home) and then all of
the sudden the dhclient will wake up and go looking for a new
address...
probably a killall dhclient will sort it out.
I wondered about it, but it didn't make sense in that the networking
system is completely ignoring its own configuration. Plus, this
behavior has survived several reboots of the system. However, I will
give that a try and see if the behavior changes.
do you have network-mangler^Wmanager installed?
perhaps some other package is starting dhclient? Basically, if you
have both interfaces using static ip, dhclient shouldn't even be
started. care to post /etc/network/interfaces?
A
For some reason dhclient WAS running, but I don't know why. Especially
on that interface as it was not chosen as the default interface during
install, and that's the only interface I've had configured to use dhcp
at any time. As I said, both interfaces specify "static" in
/etc/network/interfaces. It's working now as it's had long enough to
repeat its behavior based on the time frame of how long things took to
happen last time so I'm assuming it's fixed.
And, if dhclient was getting a new IP address for that interface, why
not for the other NIC too? What makes the Marvell interface the
interface that keeps getting reconfigured and the 3Com interface stay
stable? I've never seen this kind of thing happen before and I've
switched interfaces between static and dhcp many times. I've never had
to manually kill dhclient before to keep it from reconfiguring a
working, manually configured, interface. To me that says there is
possibly something wrong with the driver for the NIC itself and it's
crashing and losing its state or something. Nothing shows up in syslog
or kern.log, but I still wonder about it.
And, no, network-mangler isn't running or installed. It's one of the
first things I get rid of in a desktop install. IIRC, n-m only comes
with a gui, and I have no gui installed. Plus, it doesn't show up using
dpkg -l | grep network so I know it's not there This is just a base
install with the server packages I need to run for use in my lab.
Nothing else.
You wouldn't happen to have any guesses on the second problem I listed
would you? :)
