I think 0.7 would be the better choice going forward since you'd have a lot more control over the network configuration (if you need it). 0.7 is a lot more flexible and probably more suited for embedded systems where you likely want more control over the network configuration.

More over I would not have Gnome environment on the device nor I would have GTK. Nope, you can just use the NM daemon. You shouldn't need GTK or GNOME. NM has the ability to grab connections from the system settings service (nm-system-settings) as well as user connections (normally nm-applet on GNOME or knetworkmanager on KDE). Since you're not using GNOME or KDE, you can just use system connections instead. But I would like to have the authentication mechanism for the wireless, atleast WEP and WPA to begin with. With this use case scenario, can you please tell me if I can use the Network Manager and by excluding and including which components in configuration? Do I also need some kind of Keyring Manager? Which one would be suitable if I don't have Gnome? You can just use system connections with the keyfile plugin for the system settings service. You shouldn't need a keyring at all. Were you planning on allowing the user to configure the connections, or just to select between preconfigured connections, or just have everything be as automatic as possible? NM will spawn nm-system-settings via dbus service activation, and nm-system-settings will look for connections, read them in, and send them to NetworkManager. NM can then bring those connections up or take them down based on network conditions. You'll create a /etc/nm-system-settings.conf file that contains: [main] plugins=keyfile this causes nm-system-settings to load the keyfile plugin, which looks for connections in /etc/NetworkManager/system-connections. Each file in that directory is a .ini-style file describing the connection. When you get to that point, we can post some examples of keyfile connections for you. The connection files would contain the WPA or WEP key for connection to your network. Can anyone give me some inputs about configuration and dependencies when trying to do so? What do I specify for --with-distro in configuration? You could create your own distro target. It mainly affects what backend is used for some IP configuration (see src/backends/*) and not much else.

I do have OpenSSL on my device but dont have GNU TLS or Mozillaa NSS. Did you guys find GNU TLS and Mozialla NSS to be better than OpenSSL? The crypto libraries are used for reading certificates and private keys for connections to 802.1x/802.11i networks. If you don't need that functionality you could safely comment out that code in NM. It does look like OpenSSL has the functionality required, but there's no code for that yet. I can write that if you'd like (or you could too :). The one caveat with OpenSSL is that it's not GPL-compatible; which means that you can't link OpenSSL with NetworkManager and distribute the result outside your company. If you're just using NM linked with OpenSSL _inside_ your company, that's fine. You just couldn't distribute/sell/whatever the combination due to the license incompatibility
Network Manager for embedded Linux
HI! I am planning to build and test the Network Manager 0.6.5 for embedded Linux for a MIPS based CPU. Can anyone give me some inputs about configuration and dependencies when trying to do so? What do I specify for --with-distro in configuration?
