Public bug reported: Binary package hint: ifupdown
DESCRIPTION: The script /etc/udev/rules.d/85-ifupdown.rules does not allow udev to invoke ifdown when a network PCMCIA card is removed. On subsequent reinsertion of the card, ifup refuses to run because it thinks that the status is still 'UP'. CAUSE: the check DRIVERS=="?*" allows the 'add' part to be executed, but causes the 'remove' part to be skipped STEPS TO REPRODUCE: 1) insert the pcmcia card (first time it initializes properly) 2) remove (will not invoke ifdown and will leave a dhclient around) 3) insert again (will not invoke the pre-up or anything else) ENVIRONMENT: Ubuntu 7.04 ifupdown 0.6.8ubuntu6 linux-image-2.6.20-16-generic 2.6.20-16.29 udev 108-0ubuntu4 cat /etc/network/interfaces ------------------------------------------------------------- auto lo iface lo inet loopback address 127.0.0.1 netmask 255.0.0.0 auto eth0 iface eth0 inet dhcp pre-up ifconfig eth0 down pre-up iwconfig eth0 essid XXXXXXXXXXXXX pre-up iwconfig eth0 mode managed pre-up iwconfig eth0 channel auto || true pre-up ifconfig eth0 up ------------------------------------------------------------- Original /etc/udev/rules.d/85-ifupdown.rules: ------------------------------------------------------------- # This file causes network devices to be brought up or down as a result # of hardware being added or removed, including that which isn't ordinarily # removable. # See udev(7) for syntax.
