[BusyBox] udhcpc and two interfaces?

[Steven Scholz]

Hi there,

I am using udhcpc (from busybox v1.00-pre3) on two interfaces:

~ # ps | grep dhcp
    96 root        640 S   /sbin/udhcpc -i eth0 -b -s /etc/dhcpc/default.script
   262 root        624 R   /sbin/udhcpc -i eth1 -b -s /etc/dhcpc/default.script

The second instance is started by PCMCIA CS in /etc/pcmcia/network:
...
  elif [ -x /sbin/dhclient ] ; then
    log "/sbin/dhclient $DEVICE >/dev/null 2>&1" || exit 1
  elif [ -x /sbin/pump ] ; then
    log "/sbin/pump $HN -i $DEVICE > /dev/null" || exit 1
  elif [ -x /sbin/udhcpc ] ; then
    log "/sbin/udhcpc -b -i $DEVICE -s /etc/dhcpc/default.script $CI $HN"
    exit 0;
  else
...

But somehow a "killall -SIGUSR1 udhcpc" kills my second udhcpc with any further notice!
A "kill -s SIGUSR1 262" or "kill -s SIGUSR2 262" does the same.

But when I start "/sbin/udhcpc -b -i eth1 -s /etc/dhcpc/default.script" by hand (and not from
/etc/pcmcia/network) than a "kill -s SIGUSR1 262" does indeed result in a "renew".

Any ideas?

Thanks a million,

Steven
