> Ok, I added comments/summaries above each test (in fact 4 of them). Ok, thanks. So it happens that I've just done my first real etch install onto a new laptop. The desktop is great, but network-manager is /awful/ for my purposes; not because I don't want a desktop applet managing my connection -- I in fact do want this -- but because it stores all my wep keys under lock and key, and as a result my wifi connection isn't brought up until I log into the GUI. This is doubly-broken for me because I want to be able to use Kerberos for network-based login *at* the GUI... None of this is anything that I think should be RC for etch, though I look forward to trying to help find a solution better-integrated with ifupdown for lenny. In the meantime, I'll probably install waproamd for my own use. > Summaries are separated between some visible markers. > > It is certainly the case that /etc/init.d/networking should have no effect > > on interfaces that are not marked 'auto'. > allow-hotplug ones should be managed, too (according to the README.Debian > examples) Uh, I don't understand what you mean by "too". I was talking about what *ifupdown* does with interfaces that are not marked 'auto', which is: nothing. The interface is only managed by /etc/init.d/networking if it's marked 'auto'; if it's marked allow-hotplug and *not* marked auto, it's managed via the hotplug system exclusively. > > fact that it is possible in the NM applet to *override* the status of an > > interface sounds to me like a feature, not a bug. > That would be ok *if* I would still be able to use the init script to stop > and start networking from the console.

Well, at this point the problem you're describing is not reproducible for me. I've set up my ethernet interface as: # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet dhcp I have manually disabled networking with NM. I have then run /etc/init.d/networking restart, and the ethernet interface is brought up successfully, and stays up. > -------------------------------------------------- > The first situation starts with NM removed, after a reboot, with > "allow-hotplug" set in interfaces. > After "networking stop", "networking start" has no effect. > So this whole issue looks like is related both to NM and the > "allow-hotplug" vs. "auto" option. > Sorry for not provifing full information here. > -------------------------------------------------- So what I understand from this description is that 'allow-hotplug eth0' was set, and 'auto eth0' was /not/ set, so this behavior of /etc/init.d/networking is expected. > Script started on Jo 29 mar 2007 19:57:11 +0300 > debian:/# ifconfig eth0 > eth0 Link encap:Ethernet HWaddr 52:54:00:12:34:56 > inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 > inet6 addr: fe80::5054:ff:fe12:3456/64 Scope:Link > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:9450 errors:0 dropped:0 overruns:0 frame:0 > TX packets:2313 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:1000 > RX bytes:14039029 (13.3 MiB) TX bytes:149074 (145.5 KiB) > Interrupt:10 Base address:0xc100 > debian:/# ps ax | grep dhc > 1740 ?

/etc/init.d/networking doesn't bring it up because network-manager didn't bring the interface *down* using ifupdown, so ifup believes the interface is already configured (this is the same thing that happens if you run 'ifconfig eth0 down'); running stop and then start again resets this. > -------------------------------------------------- > NM installed, connection was activated the GNOME applet, the interface has > "allow-hotplug" > /etc/init.d/networking stop has no effect. > This configuration would be the one after the default install, *after* the > user realises that he has to start the interface via the applet. > -------------------------------------------------- Ah, again, in this case the eth1 interface was not brought up by ifupdown, but by network-manager; so there's no ifupdown state in /etc/network/run/ifstate telling ifdown that it needs to act on this interface. I agree that this is surprising; perhaps network-manager could be fixed to write to /etc/network/run/ifstate for better integration?
