Is this a bug in NetworkManager or Firefox ?This is odd behaviour and needs to be fixed. I would suggest open up a bug against firefox. I know one can change toolkit.networkmanager.disable preference, but it is a PITA for our users. One of use cases is: Sometime network manager does not connect me via my CDMA usb modem (in case signal is weak), but wvdial does and once I switch from NM to wvdial, my firefox gets to offline mode, which I don't expect it to as I am connected.Ok, filed as: 542078NetworkManager is intended to control the default internet connection. If NetworkManager cannot control the default internet connection, then you may not want to use NetworkManager. In your case, you're using a mobile broadband device. The real bug here is that for whatever reason, NM/MM aren't connecting your modem, and we should follow up on that bug instead. DanI am not using a mobile broadband device. The network connection my systemsMy mistake. I guess it was Rakesh Pandit who was using a CDMA 3G connection.use is not just the Internet it is a local network LAN connection that also serves the internet. Most of my systems use a local network server which provides NIS, /home and /data using NFS and VPN etc. I normally use the service "network" to bring up wired or wireless networking for this. Fedora, by default, uses NetworkManager to manage all network devices though. I use the service "network" as, for some reason, the NetworkManager service is started after the netfs and other services are started. Is there a reason for this ??No particular reason, in fact that looks like a bug. NM no longer depends on HAL, but that dependency is still in the initscript, which looks like it pushes NM later than netfs. But in reality, you're looking for a dependency based initsystem which we don't quite yet have. There are already scripts that kick netfs to mount stuff when NM brings the network up (/etc/NetworkManager/dispatcher.d/05-netfs), so you get asynchronous bootup *and* your mounts. The rest of the system, if it requires something from the mounted directories, needs to be smart enough to know that. If you need to, you can set NETWORKWAIT=yes in /etc/sysconfig/network, which causes the NetworkManager initscript to block until a network connection is brought up, or 30 seconds have passed.I can obviously turn of the NetworkManager service, which I have done on the desktop systems. However, I also have a few Laptops that can roam. In F11 and before I have used the network and NetworkManager services. When the laptop boots away from home, the "network" service fails and I can then use the NetworkManager service to connect to whatever wireless network or G3 network is available. It does seem sensible to me that the "system" provides applications with info on if the network is up (not just the Internet). The NetworkManager service seems the place to do this and it looks like the applications are starting to use it for this purpose. So maybe a generic NM "isNetworkUp()" API call is called for ?See the other mail; the problem with a generic isUp() is that it simply says hey, is there a connection? It doesn't provide enough information about the networking state of the system for anything to make an intelligent decision about anything. It's a "hey I'm connected to something" but there's no information about *what* you're connected to; whether it's a secure home network, whether it's a slow 3G network, whether it's billed by the minute or the hour or unlimited, etc. DanHi, Thanks for the info. I would have thought that a generic isUp() is good enough for the likes of Firefox and Pidgen though to decide if to start offline. Being connected to a Network is probably all you need, you may be accessing an Intranet as all my systems Firefox home pages do ... Anyway, following your email (And notes in Bugzilla) I thought I'd try and use NM properly for my config. However I have a problem, which may be a bug. I have turned off the Network services and turned on NetworkManger. I have two main network interfaces eth0 (wired) and eth1 (Wifi), both are set to be managed by NM and to start at boot. I have also added NETWORKWAIT=yes in /etc/sysconfig/network. When I boot with this the network (eth1 (eth0 is disconnected)) does not come up at boot. There is a message stating a failure on the line where it is waiting for the network to come up. When I log in as a local user the network then comes up ... I also note that, before the user is logged in, I cannot start the network with "service network start" and the WiFi light is off. It looks like NM has done something like powered down my WiFi chip ? (Intel Corporation PRO/Wireless 2915ABG IBM Thinkpad R52) Another thing, I would need NETWORKWAIT=yes as I have ypbind enabled. Maybe ypbind should be modified to not start when the network is down and also added to /etc/NetworkManager/dispatcher.d ?NM has two types of connection: system and user (see http://live.gnome.org/NetworkManagerConfiguration ). NM treats ifcfg files as system connections and thus they are available at boot time and before login. I had assumed that since your connection was working correctly with the 'network' service that it was also a system connection. What is the result of 'ls /etc/sysconfig/network-scripts/ifcfg-*' and what are the contents of /var/log/messages when the device is not correctly connected on bootup? Before logging in, can you also drop to a VT, log in, and run 'nm-tool' for me? THanks, DanHi Dan, As far as I am aware my connections are "system" connections. I have configured the Network interfaces using the system-config-network tool. When I use the "network" service the eth1 wireless network comes up fine at boot. When I use NetworkManager the eth1 wireless network does not come up at boot. There is the error: "Waiting for network... [FAILED]" If the NetworkManger service is running (eth1 has not come up) and I run "service network start" the eth1 interface still does not come up. If I stop the NetworkManger service and again run "service network start" then the eth1 interface comes up ... The configuration files are: /etc/sysconfig/network-scripts/ifcfg-* files are there: /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/sysconfig/network-scripts/ifcfg-lo /etc/sysconfig/network-scripts/ifcfg-Vodaphone /etc/sysconfig/network-scripts/ifcfg-eth1 is: # Intel Corporation PRO/Wireless 2915ABG [Calexico2] Network Connection DEVICE=eth1 HWADDR=00:16:6F:8A:E1:95 ONBOOT=yes BOOTPROTO=dhcp TYPE=Wireless NM_CONTROLLED=yes USERCTL=yes PEERDNS=yes IPV6INIT=no MODE=Auto^^^^ This is the problem. "Auto" is not a valid mode. Dec 1 09:59:05 think NetworkManager: ifcfg-rh: error: Invalid mode 'auto' (not 'Ad-Hoc' or 'Managed') you'll probably be seeing something on the console when running "ifup eth1" like this: Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Invalid argument. Since all ifup-wireless does is send $MODE to iwconfig, and "auto" is not a valid mode.
The "MODE" was set up by system-config-network, it is from its list of possible options for Mode and I think was the default. If I run ifup the error you mention is not reported and the interface comes up fine. However, I do get the error: domainname: you must be root to change the domain name Which I assume is due to another F12 bug. Could this cause NM to abort the connection ?
