setting up WPA Personal (F9 & KDE 4.1 (from updates-testing))

[Michael Park-3]

Hi there,

I read here ( http://www.kdedevelopers.org/node/3462 ) that KDE 4.1's
getting a plasmoid front-end to NetworkManager (which doesn't seem to
be in 'updates-testing' yet). Till that arrives, can someone either
point me to a howto or explain how I can go about setting up a WPA
connection for an Intel 4965 AGN wifi adapter (Thinkpad T61).

I tried playing with 'system-config-network' and it seems to be
lacking any WPA configuration options. Can anyone help point me in the
right direction?

The Gnome nm-applet works fine under KDE.

The community wisdom around here is that you should choose between
system-config-network and NM, but don't try to mix them as they don't
get on, i.e. disable one or the other. On the whole NM seems better
suited to wireless, though personally I use it with a wired connection
and haven't had problems.

Hi Patrick,

Thanks for the reply.

So I tried that, specifically I did a:

[bailey@homer:~]$ sudo yum install NetworkManager-gnome

...which pulled in 'gnome-panel' and 'gnome-panel-libs'. However, when
I tried to start 'nm-applet', I got the following error:

[bailey@homer:~]$ nm-applet

** (nm-applet:6268): WARNING **: <WARN>
applet_dbus_manager_start_service(): Could not acquire the
NetworkManagerUserSettings service.
  Message: 'Connection ":1.344" is not allowed to own the service
"org.freedesktop.NetworkManagerUserSettings" due to security policies
in the configuration file'


(nm-applet:6268): GLib-GObject-CRITICAL **: g_object_unref: assertion
`G_IS_OBJECT (object)' failed

...same thing happened when I tried it as 'sudo' (also, when I
restarted both 'network' and 'NetworkManager' services). Is this a
dbus problem or some kind of PolicyKit thing?

Hmm, all I can say is it works for me and I didn't do anything special.
Does it work under Gnome?

When I was using F7, I remember that there was something like
KNetworkManager, that runs as an icon in the system tray in KDE. It
also allows you to see the available wireless networks, the SSIDs, and
the signal strengths of each wireless network found.

The NetworkManager for gnome does not show these available wireless networks.

It does here (NetworkManager running on Gnome on Fedora 9).  Are you
sure that it's not just that those networks aren't around anymore?

Unleswsw things have changed radically system-config-network works with
network not networkmanager.

You need all the rpms below installed for it to work.

On F9, the NetworkManager applet makes you ADD the wireless network MANUALLY.
There are "Wired", "Wireless", "Mobile Broadband", "VPN", "DSL" tabs.
On each of those tabs, you have "Add", "Edit", and "Delete" buttons.
They don't show you the available wireless networks that it detects,
but you have to add them yourself, specify the SSID, etc.

Are we talking about the same NetworkManager ?

At least on my laptop, running Fedora 9 with KDE, clicking the
NetworkManager icon in the tray immediately shows me the available
networks, just as in Fedora 8. I never need to manually specify an
SSID. Easy and powerful.

Likewise, here with 9 and using Gnome.  I wonder a couple of things:
Whether the original poster has tried both right clicking and left
clicking on the network manager icon.  And whether they're trying to use
access points that aren't broadcasting their SSID (which is a complete
waste of time).

Here, if I left click on the icon, I see a list of available networks
(wired and wireless), and I can select one of them, there's also some
options about manual configuration.  If they need authentication for
use, then I'm prompted to enter the necessary information.

If I right click, there's enabling options, and manual editing options.

Yes it is the same, however, we have to be more exact in our
communication. If you have a wired connection that will be detected and
the connection made without your having to do anything. Any WEP, WPA,
etc networks that are available will appear with their SSID under the
nm-applet and clicking on one of them will allow you to put in any
security information that is needed and the connection will be made.
That information will be remembered for future connections.

I have not had access to any VPN Connections so I am not sure how this
works.. But you certainly don't have to add any of these connections
manually.

        I have to be missing something here. Why do the wireless settings
on my router allow me a separate choice whether to broadcast SSID, if one
that isn't doing it is useless??

I think you misunderstand what Tim is trying to say.  To make a router
not broadcast its SSID in the hopes of being more secure is a waste of
time.  It does *NOT* make your connection any more secure.  Anyone
sniffing for SSID broadcast packets won't see it, but, anyone sniffing
for ALL packets will eventually see packets destined for your "hidden"
SSID while your wireless is active.  So to *not* broadcast your SSID is
a waste of time.  "iwlist scan" (amongst other tools, I'm sure) will
find networks without an SSID being broadcast and print out their
channel number and encryption details.

It doesn't make the access point useless, but it unnecessarily complicates the
life of the users of the AP, and doesn't protect against malicious
users. When the
station sends anything, it can be detected anyway.

As a (false) security idea, not broadcasting it is a useless thing to
do.  It actually causes more problems:  How do manual and automated
systems connect to the right access point, when they don't name
themselves?  (It's doable, but abnormally.)  More so when presented with
several unidentified access points, and you're only supposed to use a
particular one of them.  You might keep trying to use the wrong one(s),
you might actually keep on using the wrong ones (on unencrypted
systems).  The list goes on and on with things that's wrong with hiding
SSIDs.  There is no benefit in doing so.

As to *why* a device gives you an option to hide the SSID, good
question.  I can't think of any good reason to give you the option,
considering that it only causes harm, not good.  It's probably offered
to appease stupidity amongst the cargo cult breed of users.

A much more useful thing would be for the manufacturers to either make
sure that devices all had a unique ID, by default (e.g. something
matching a sticker on the device), which would still allow network
admins which want to have multiple devices with the same ID (for special
purposes), by manual reconfiguration, but keep SSIDs unique for everyone
else (which is the normal requirement - different networks should have
different IDs).  That'd avoid the problem that I would see in many
homes, where the network configurators would present a list of several
access points (yours and the neighbours), all with the same name
(something like "AP325"), and the only way you could pick yours from the
neighbours was by signal strength (which is open to error).

Personally, I think wireless access points are a bad idea for personal
use.  The average user doesn't have a clue about them.  The average
access point seems to default to no security, wireless is active,
default passwords, configuration allowed over the wireless link, and the
same SSID as other access points.  That means that most people have an
unsecured network, and that their neighbour can reconfigure it,
accidentally or on purpose.
