Network Manager and DHCP

Hi all,
I've just installed the latest NetworkManager, and while it itself managed to connect to the wifi, I still don't get internet access unless I manually launch dhclient under root.

This happens on every boot, obviously, so to make ot a bit more bearable, I tried adding dhclient -nw to /etc/rc.local, but the situation still happens if I suspend/hibernate the laptop.

I haven't changed my config files from when I was using the previous NetworkManager -- which worked correctly, and I never touched dhclient before this day.. Any ideas?

Here are the relevant sections of my config files -- if I need to put any more, pls tell me :

/etc/rc.conf

HOSTNAME="jean-laptop"
wlan0="dhcp"
#lo="lo 127.0.0.1"
#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
INTERFACES=(!lo !eth0 !dhcp wlan0)
#
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
#   - prefix an entry in ROUTES with a ! to disable it
#
gateway="default gw 192.168.0.1"
ROUTES=(gateway)
DAEMONS=(syslog-ng !wicd  hal dhcdbd networkmanager fam !mysqld @cups @stbd @ntpd @portmap @alsa  @crond @openntpd)

# A sample configuration for dhcpcd.
# See dhcpcd.conf(5) for details.

# dhcpcd-run-hooks uses these options.
option domain_name_servers, domain_name, domain_search, host_name

# Most distros have ntp support.
option ntp_servers

# We should behave nicely on networks and respect their MTU.
# However, a lot of buggy DHCP servers set invalid MTUs so this is not
# enabled by default.
#option interface_mtu

I edited dhclient.conf thinking it might help..

It wasn't even there before..

interface "wlan0" {
   send dhcp-client-identifier 00:19:D2:9A:A6:06;
}

/etc/resolv.conf

search lan
nameserver 192.168.1.254

/etc/var/messages.log when resuming from suspend :

Re: Network Manager and DHCP

this might not be causing the problems, but you might want to remove dhcdbd from the DAEMONS list and also not activate gateway in rc.conf as a route.
dhcdbd isn't used anymore by networkmanager and the route should be added automatically.
i've never had this problem with nm 0.7 myself and been using it since february, so no other idea...

Re: Network Manager and DHCP

Thanks for your answer, but it didn't work for me. Can you paste the relevant sections of the relevant configuration files here please? I think I might have screwed up something in the /etc/rc.conf :S

Re: Network Manager and DHCP

do you have dhcpcd installed? nm 0.7 uses dhcpcd instead of dhclient by default, so it seems there is something wrong with that.
oh and !dhcp can be removed from INTERFACES aswell, what does that even do?

as i said above, the things i mentioned before weren't fixes for your problem, so it's no wonder they didn't solve your problem
they were just cleanups for your networking stuff and to make nm really do the part it is supposed to.

Re: Network Manager and DHCP

Have you tried connecting manually with ifconfig / iwconfig and dhclient? Using the output you get then might help you situate the problem...

I am not a big fan of nm and prefer the use of netcfg, but when in trouble, I switch to manual mode and try to understand the output. Last week I found out that I had both dhclient and dhcpcd running and they were interfering with each other: every 2 minutes my ip changed from x.x.x.168 to x.x.x.167 :-)

Re: Network Manager and DHCP

I haven't tried using ifconfig/iwconfig to do this.
I removed dhclient, and tried it using dhcpcd. I now have the same problem - I have to run dhcpcd wlan0 to get the dhcp working.

Re: Network Manager and DHCP

dhcpcd is having problems for some (version 4 at least) - try the other one

Re: Network Manager and DHCP

I think I have solved the problem temporarily, at least. I compiled my own version of networkmanager using dhclient from abs, then I made sure to lock the /etc/hosts as I noticed it was becoming overwritten - with the result that GNOME apps wouldn't even launch because of lines being added like :

127.0.0.1    unknown-00-19-d2-9a-a6-06.lan    localhost.localdomain    localhost

A quick chattr +i /etc/hosts later, and I was in business.

Thanks for all help given!

Now things seem to be working seemlessly.
