[SOLVED] wicd connecting to secure network (Buttons not working)

kens · 2012-05-04 17:30:35

Hello all,

I have a laptop with a Broadcom 4312 wireless card in it. I have followed the wiki and installed the broadcom-wl drivers. I am trying to use wicd to setup my wireless.

When I open wicd-gtk, I get a list of wireless networks, one of which is mine. I try to connect to it, and it says I need a password and it opens up the Settings page for that network. Then I type in my password, but when I hit OK or Cancel, nothing happens. If I start wicd from a terminal, I see this as output:

$ wicd-gtk

I tried using the ncurses client but I get the same error. Also I tried editing /usr/lib/python2.7/site-packages/wicd/misc.py on line 433 and changing s.translate(None, table) to just s.translate(table), but I get the exact same error (2 arguments instead of 1, even though in the error message it shows the line as s.translate(table) which only is one argument).

Does anyone know how to fix this error? It's stopping me from using wireless, since I can't get wpa_supplicant working either.

I have the same Problem since the update.

frette · 2012-05-04 23:40:08

same here, kinda looks like a nasty little bug

mr.MikyMaus · 2012-05-05 00:03:09

BC 4312 sucks, got it too and always had nothing but trouble. Using opensource driver though - you may give it a try, although this look more like a Wicd bug.

Anyway, how come you cannot get wpa_supplicant working? Maybe it's related...

frette · 2012-05-05 00:07:41

might very well be (although I doubt it), since afaik wicd uses wpa_supplicant. This most definitely doesn't look like a driver issue though, it's just like kens wrote: when you click ok to save the password, nothing happens

edit: and my wlan connection worked a few days ago when I last needed it

edit2:
ok, I now did what I should have done first: I read the bloody error...

  File "/usr/share/wicd/daemon/wicd-daemon.py", line 1067, in SetWirelessProperty
    prop = misc.sanitize_config(prop)
  File "/usr/lib/python2.7/site-packages/wicd/misc.py", line 433, in sanitize_config
    return s.translate(None, table)
TypeError: translate() takes exactly one argument (2 given)

sanitize_config is called just before saving the config I guess, and translate is simply called with 2 arguments instead of 1. Sounds like a simple coding error, good chance to have a look at the code I guess .

edit3:
ok, I'm too tired to fix this, but they fiddled around with this function, old version:

def sanitize_config(s):
    """ Sanitize property names to be used in config-files. """
    s = s.strip()
    s = s.replace('=', '')
    s = s.replace(' ', '')
    s = s.replace('\n', '')
    return s

new version:

def sanitize_config(s):
    """ Sanitize property names to be used in config-files. """
    allowed = string.ascii_letters + '_' + string.digits
    table = string.maketrans(allowed, ' ' * len(allowed))

    return s.translate(None, table)

just replacing the function won't work, the upper layer obviously changed, too. I'll try a rollback and see what happens.

edit4:
rollback produces the same error I got when I switched the functions... since I'm almost falling off the chair I'll call it a day...
here is the rollback error if anyone cares:

ok, Im posting via wlan

The problem was actually not the changed function I mentioned above, but how it was called.

It's called in /usr/share/wicd/daemon/wicd-daemon.py lines 1067 and 1411 (and 1268, but I didn't change that) with prop as argument. The error we see is a unicode error. So I fiddled around a bit and a simple string cast does the trick.

so just change the aforementioned lines from

prop = misc.sanitize_config(prop)

to

prop = misc.sanitize_config(str(prop))

and everything should be fine

obviously I don't guarantee anything and you are doing this at your own risk.
If you didn't understand a word of what I said, you're probably better off waiting for a patch.

Have a nice day (and I'm finally going to bed now xD)

edit: don't forget to restart the wicd daemon

frette, I tried using the old function and it worked just fine for me. What did it do for you? Keep in mind you'll have to restart wicd for change you make to take effect.

The problem here is they're assuming the string is an ascii string, when it's actually a unicode string. Here's a fix that works for the newer code;

def sanitize_config(s):
    """ Sanitize property names to be used in config-files. """
    allowed = string.ascii_letters + '_' + string.digits
    table = string.maketrans(allowed, ' ' * len(allowed))

    return str(s).translate(None, table)

The only change is on the last line. Make no mistake, that's a bad solution for handling unicode.

The problem is that DBus is sending a unicode string through to wicd, which wicd is not expecting. I tried the other route of modifying sanitize_config to better handle unicode strings, but that had... side effects. Like storing the reprs of lists in my /etc/wicd/wireless-settings.conf.

The more correct fix would be to update wicd to use unicode strings, which I imagine would be a rather large undertaking. Today my first encounter with wicd at all, let alone the code, so I couldn't say for sure how easy this change would be.

Edit: I hadn't refreshed before I posted this. Glad you found a fix in the end!

my fix is for the newer code too and it works fine for me

you simply do the string cast one step later, which results in fewer changes

snoxu · 2012-05-05 03:28:45

I don't fully understand the fix, but you're my personal Jesus!

I've recently installed Arch and stumbled upon this thread after hours of racking my brain over why Wicd would not allow me to save any networks settings, making it completely useless. I was about ready to jump ship and install NM.

Hiram · 2012-05-05 03:28:51

Yeah, they both work, which is the important thing

ewaller · 2012-05-05 18:16:18

Yep, that fixed it. Thanks all, and good job.
If anyone needs it, here is the patch for extra/wicd 1.7.2.4-1 /usr/share/wicd/daemon/wicd-daemon.py:

1067c1067
<         prop = misc.sanitize_config(prop)
---
>         prop = misc.sanitize_config(str(prop))
1411c1411
<             prop = misc.sanitize_config(prop)
---
>             prop = misc.sanitize_config(str(prop))

This was reported upstream already: https://bugs.launchpad.net/wicd/+bug/993912
Here is the Arch Linux bug: https://bugs.archlinux.org/task/29709

Hopefully they will release a bugfix release soon...

netherscythe · 2012-05-05 21:25:25

Hi everyone,

I was having the same problem. Frette, your solution fixed it for me, thank you!

kens · 2012-05-06 16:00:23

Thanks guys, the fix indeed worked. I now know that it was because I didn't restart the wicd daemon that it was giving me an irrelevant error when I edited the python file

It still can't connect to networks with hidden SSID's though for some reason, it always fails with 'bad password' in the console. I unhid the SSID of my router and it actually gets connected, but seconds later it drops the connection and goes back to "unconnected". That's an unrelated problem though, so I'll start a new thread or something if I can't get it working. Thank you all for the help, I had to apply this patch to my other 2 computers running Arch too

ewaller · 2012-05-07 01:00:12

It would appear that today's update to 1.7.2.4-2 has fixed the problem

frette · 2012-05-07 11:56:02

Good to know, and a good chance to see how they actually chose to fix it
(I actually liked Hiram's fix more than my own tbh and am using his )

edit: and so did the wicd devs I just had a look at the code
