Binary package hint: network-manager
I'm using Intrepid Ibex, just upgraded from Hardy.
The version of network-manager is svn20081018t105859-0ubuntu1, but I
don't know if that was the version which broke the configuration, or if
network-manager has been upgraded in Intrepid since October 26th.
Since the upgrade, a previously working laptop with wired and wireless
networks broke both. The wireless breakage is perhaps reported
elsewhere; this is about the wired connection.
Previously, it would use DHCP on eth0 if there was a cable plugged in.
Very sensible.
Now, the nm-applet dialog shows:
Wired connections
ifupdown (tap2)
ifupdown (tap0)
ifupdown (tap1)
Wireless connections
[access points if any]
When I plug a cable into eth0, it then assigns a _static_ configuration
to eth0, which has no relevance to eth0. (This is the opposite of a
bug others have reported where static configurations change to DHCP
after upgrade :-) )
Specifically, after plugging in a cable, nm-applet shows it has selected
"ifupdown (tap1)", and is applying static IP 10.1.1.1 to _eth0_, which
is the static IP that is given for tap1 in /etc/network/interfaces.
My full /etc/network/interfaces, with comments removed, is as follows:
auto lo
iface lo inet loopback
iface ppp0 inet ppp
provider BluetoothDialup
iface ppp1 inet ppp
provider free-dialup
iface ppp2 inet ppp
provider cameldial
iface ppp3 inet ppp
provider freeukisp
iface ppp4 inet ppp
provider 123-reg
auto ppp0
auto tap0
iface tap0 inet static
address 10.1.100.1
netmask 255.255.255.0
tunctl_user jamie
auto tap1
iface tap1 inet static
address 10.1.1.1
netmask 255.255.255.0
tunctl_user jamie
auto tap2
iface tap2 inet static
address 10.1.2.1
netmask 255.255.255.0
tunctl_user jamie
Sometime in the past, it also has "auto eth0" and maybe "iface eth0 inet
dhcp", but I removed those to let NetworkManager handle eth0 in Hardy.
Intrepid selected "ifupdown (tap1)" and proceeds to set eth0 to its
settings, which have never been appropriate for eth0:
[EMAIL PROTECTED]:~$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:16:36:4f:e6:80
inet addr:10.1.1.1 Bcast:10.1.1.255 Mask:255.255.255.0
inet6 addr: fe80::216:36ff:fe4f:e680/64 Scope:Link

TX packets:49 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:5265 (5.2 KB)
So my questions / bug report are:
- Why did it create "ifupdown (tap0)" (+tap1, +tap2) connections?
(I can see them in Edit Connections in nm-applet, btw).
- Having imported data for those connections on upgrade to Intrepid,
why does it then _apply_ the settings for tap1 to eth0???!!!! That is
obviously wrong.
- Why does it not have a DHCP connection under the Wired Networks
created, since that's what eth0 was doing before the upgrade.
I've worked around this by running "sudo dhclient eth0", and later by
creating another connection in Edit Settings called simply "DHCP", and
explicitly selecting that. I've no idea what the normal process would
have called the connection, and it's kind of ugly to have: "Wired
Settings" "DHCP" in nm-applet's main window, but that's purely cosmetic.
I'd provide a screenshot, but Alt-PrintScreen doesn't work when nm-
applet's main selection window is popped up.
Thanks.
