Re: CVS (STABLE_0_3) works for Madwifi/Atheros, but starts too late
Quoting Dan Williams [EMAIL PROTECTED]:
In GDB, when you get here, can you do:
print dhcp_resp
print dhcp_resp.dhcp_msg
print dhcp_resp.dhcp_msg.options
And send along the results? That should give me the actual packet the DHCP
server passed back.
It looks like the DHCP client is _thinking_ that it got data, but really it
didn't. It also feels to me like it's a race condition, because it is much
harder to reproduce since I installed the debuginfo package (whereas it
happened really quick without it).

So it should only be listening to the 802.3, not 802.11. However there is definitely a correlation between these error messages and the crash.

Re: CVS (STABLE_0_3) works for Madwifi/Atheros, but starts too late
Quoting Dan Williams [EMAIL PROTECTED]: NM is likely to be very unhappy if you just suspend it, and wireless drivers in general have issues with suspend. There really is no method for NM to know when you've put the computer to sleep since nothing sends global events out (PowerManager+HAL will eventually do this the Right Way using dbus). I already fixed the device issue in my acpi scripts.. I ifdown the interface manually and then rmmod all the device modules (I have no idea why modprobe -r doesn't DWIW). This seems to work fine as far as the module itself is concerned. NM does have a sleep dbus method that will make NM stop and down all devices, and a wake method to wake it up. Those should be able to be done in the ACPI scripts fairly simply: Ooh, this is useful to know. Is this documented somewhere? I'll try this and see if it works. Thanks! /usr/bin/dbus-send --system --dest=org.freedesktop.NetworkManager --type=method-call /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.sleep sleep 5; and: /usr/bin/dbus-send --system --dest=org.freedesktop.NetworkManager --type=method-call /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.wake Dan -derek -- Derek Atkins, SB '93 MIT EE, SM '95 MIT Media Laboratory Member, MIT Student Information Processing Board (SIPB) URL: http://web.mit.edu/warlord/PP-ASEL-IA N1NWH [EMAIL PROTECTED]PGP key available ___ NetworkManager-list mailing list NetworkManager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

Quoting Bill Moss [EMAIL PROTECTED]:
Starting dbus, hal, and NM early will work in the wired case because a
connection is established before nm-applet is run so ntpd will find a
connection when it runs later, but this won't work for wireless because
a connection will not be made until nm-applet runs after all the init
scripts have run. Am I missing something?
I guess that was my question. Does NM need the applet in order to select the
wireless network (and WEP key)? Or will NM have access to the list of
preferred networks (and WEP keys) before I login? I would certainly prefer if
the list were global instead of per-user.
No, the wireless networks are per-user and until you log in to start GConf,
they
are not available to NetworkManager.
If ntpd doesn't find a connection when it is run, it becomes brain dead
and will not work until restarted. Depending on the order of init
scripts is problematic. Network dependent services need some way to be
told that a link is available or some way to be started or restarted
when a link becomes available.
Yep, this is indeed my problem. Currently (well, before I got NM working at
all) I was logging in as root, setting up my network, re-starting my services
(like ntpd) that failed during bootup, then logging out and logging in as me.
I would prefer if NM could do all this during the boot sequence, even with
wireless.
You might want to investigate using NetworkManagerDispatcher. You can drop a
script into /etc/NetworkManager.d that will be executed by
NetworkManagerDispatcher when connections go up or down. Then you can kick
ntpd
manually.
I am running Head 1.361 under FC4 Test 3 on a T42. All seems very stable
including vpnc support.
I haven't tried vpnc support. However I do have a problem with vpnc and ncsd
and selinux:

I've noticed a few of these too, I've spoken with Dan Walsh (an SELinux guy at
Red Hat) and he's aware that we need more finely tuned policy for
NetworkManager.
