Package: wicd Version: 1.5.9-5 Severity: important Hello,
wicd has been choosen to be the default WiFi manager on Debian on the Openmoko FreeRunner. Since I am working to solve bug #520014 [1], I tried to install it without fulfilling its dependencies and I got an IMHO completely unrelated error. [1] http://bugs.debian.org/520014 BTW, the severity of this bug is important, but I consider it to be more than that, especially in such situations (like on the Openmoko FR) where you are working remotely, since you lost the connection to the device. Here what happens: ===== debian-gta02:~# ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:22 errors:0 dropped:0 overruns:0 frame:0 TX packets:22 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2144 (2.0 KiB) TX bytes:2144 (2.0 KiB) usb0 Link encap:Ethernet HWaddr de:d2:78:7e:81:d8 inet addr:192.168.0.202 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::dcd2:78ff:fe7e:81d8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:954 errors:0 dropped:0 overruns:0 frame:0 TX packets:522 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:367137 (358.5 KiB) TX bytes:71125 (69.4 KiB) debian-gta02:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 usb0 0.0.0.0 192.168.0.200 0.0.0.0 UG 0 0 0 usb0 debian-gta02:~# cat /etc/resolv.conf nameserver 208.67.222.222 nameserver 208.67.220.220 debian-gta02:~# apt-get --download-only install wicd Reading package lists...

Since I can reproduce this every time I install wicd on my FreeRunner, I tried again in a screen session. There, the dpkg process finished correctly, but there is clear a problem, since the usb0 interface got misconfigured: ===== debian-gta02:~# ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) debian-gta02:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface debian-gta02:~# cat /etc/resolv.conf nameserver 208.67.222.222 nameserver 208.67.220.220 debian-gta02:~# ifup usb0 ifup: interface usb0 already configured debian-gta02:~# ifdown usb0 SIOCDELRT: No such process debian-gta02:~# ifup usb0 debian-gta02:~# ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) usb0 Link encap:Ethernet HWaddr 76:aa:86:f6:29:73 inet addr:192.168.0.202 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::74aa:86ff:fef6:2973/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1085 errors:0 dropped:0 overruns:0 frame:0 TX packets:1028 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:68000 (66.4 KiB) TX bytes:265455 (259.2 KiB) debian-gta02:~# ===== First problem: why wicd wants to manage the usb0 interface? It is *not* a WiFi interface (read the whole mail before replying to this point) nor, according to /usr/share/doc/wicd/README.Debian, it is listed as "usable" in /etc/network/interfaces: --8<---------------cut here---------------start------------->8--- wicd for Debian --------------- If Wicd fails to connect after you install it, make sure that the only entry in your /etc/network/interfaces file is auto lo iface lo inet loopback You can change the contents of this file by using various editors, but remember: you have to be root! --8<---------------cut here---------------end--------------->8--- Indeed, the /etc/network/interfaces for my FR contains more than that: ===== # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8) # The loopback interface auto lo iface lo inet loopback # Wireless interfaces iface eth0 inet dhcp wireless-power on wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf # Ethernet/RNDIS gadget (g_ether) # ... or on host side, usbnet and random hwaddr allow-hotplug usb0 iface usb0 inet static address 192.168.0.202 netmask 255.255.255.0 network 192.168.0.0 gateway 192.168.0.200 up echo nameserver 208.67.222.222 >> /etc/resolv.conf up echo nameserver 208.67.220.220 >> /etc/resolv.conf # Bluetooth networking iface bnep0 inet dhcp debian-gta02:~# ===== Second problem: oh, wicd is *both* a wired and wireless connection manager, so it is normal that it wants to manage the usb0 interface as well. However, why should it put every interface down when the daemon starts?

The correct behavior should be to check each interface status and act accordingly. This however *only* for the interfaces the admin wants to be managed by wicd: in my case, it is clear that usb0 does not belong to this group (and IIRC network-manager would skip it). FYI and for the sake of completeness, /var/log/wicd/wicd.log continues with the following lines: --8<---------------cut here---------------start------------->8--- 2009/03/23 13:55:59 :: Exception in thread Thread-1: 2009/03/23 13:55:59 :: Traceback (most recent call last): 2009/03/23 13:55:59 :: File "/usr/lib/python2.5/threading.py", line 486, in __bootstrap_inner 2009/03/23 13:55:59 :: self.run() 2009/03/23 13:55:59 :: File "/usr/share/wicd/wicd/networking.py", line 914, in run 2009/03/23 13:55:59 :: self.release_dhcp_clients(wiface, liface) 2009/03/23 13:55:59 :: File "/usr/share/wicd/wicd/networking.py", line 335, in release_dhcp_clients 2009/03/23 13:55:59 :: liface.ReleaseDHCP() 2009/03/23 13:55:59 :: File "/usr/share/wicd/wicd/wnettools.py", line 531, in ReleaseDHCP 2009/03/23 13:55:59 :: cmd = self.DHCP_RELEASE + " " + self.iface + " 2>/dev/null" 2009/03/23 13:55:59 :: TypeError: unsupported operand type(s) for +: 'NoneType' and 'str' 2009/03/23 13:55:59 :: --8<---------------cut here---------------end--------------->8--- This is normal, since the none of DHCP clients wicd depends on is installed.
