My box has two network cards, one ethernet card (using sky2) and one
wireless card (ipw2200). The ethernet connection is faster than the
wireless (802.11b) but I keep the wireless around as the router it is
attached to is easier to configure vis-a-vis port forwarding.
The sky2 is eth0, the ipw2200 is eth1. They have both coexisted
succesfully for a long while. As of recently though they do not (since
the problem is intermittent and networking sometimes works, I can't
pinpoint exactly when the change occurred, but was I believe in the
last couple weeks).
Both interfaces are assigned addresses from their respective routers via
DHCP: sky2 gets 10.0.9.*, ipw2200 gets 192.168.0.*
The problem is ifup seems to be getting the interfaces mixes up.
ifconfig currently shows
eth0 Link encap:Ethernet HWaddr 00:16:E6:82:E4:E0
inet addr:192.168.0.107 Bcast:192.168.0.255
Mask:255.255.255.0
...
eth1 Link encap:Ethernet HWaddr 00:16:6F:B0:53:E9
inet addr:10.0.9.3 Bcast:255.255.255.255 Mask:255.255.255.0
and my connection works, even though eth1 (supposed to be ipw2200) has
an address in the range assigned by the router to which eth0 (sky2) is
physically attached.
iwconfig shows
eth0 no wireless extensions.
eth1 IEEE 802.11b ESSID:"dlink"
According to iwconfig, eth1 is the wireless card (as it should be) but
ifconfig shows that eth1 has an address assigned by the wired router.
This _works_ but is highly strange.
Worse is that running ifup -a again (through /etc/init.d/networking
restart, or directly, or by rebooting or whatever) returns completely
random results. Running ifdown -a and then ifup -a right now shows
dhcpcd.sh: interface eth0 has been configured with new IP=10.0.9.4
dhcpcd.sh: interface eth1 has been configured with new IP=10.0.9.3
so now both interfaces have an address in the range assigned by eth0
(sky2)'s router. Doing the same thing again may show both with a
192.168.0.* address. It is completely inconsistent. The practical
effect is a 50/50 chance of no working network connection on any
reboot/networking restart/ifup -a
ifconfig now shows
eth0 Link encap:Ethernet HWaddr 00:16:E6:82:E4:E0
inet addr:10.0.9.4 Bcast:255.255.255.255 Mask:255.255.255.0
...
eth1 Link encap:Ethernet HWaddr 00:16:6F:B0:53:E9
inet addr:10.0.9.3 Bcast:255.255.255.255 Mask:255.255.255.0
From what I understand modules may not always load in the same
order, and that sky2 might not always be eth0, and ipw2200 might not
always be eth1. But without even rebooting, to run ifup -a and come up
with different results each time is very disconcerting, and certainly never
happened before.
I just can't figure out why ifup gives different results each time
(not something that happened previously) and why both cards, connected
to different routers can appear to have an address assigned by the
same router, or both with an address assigned by the router to which
they are not connected, etc.
If the bug is elsewhere, I'd appreciate any assistance tracking it down.
