Hi all,
Just an issue i found when doing a little test with ping applet. Using
current git i build busybox with only "ping" applet:
busybox.git$ git rev-parse HEAD
0ad438b12a97159c43c9bfc75a4ae4873ecf9bf9
busybox.git$ make allnoconfig
busybox.git$ make menuconfig
(select just ping applet)
busybox.git$ make
After compiling i make a little test with the "-I" option of ping.
According to ping's help:
"-I iface/IP Use interface or IP address as source"
I have a network card in my PC with IP address 192.168.105.1.
busybox.git$ ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:0e:0c:34:11:fa
inet addr:192.168.105.1 Bcast:192.168.255.255 Mask:255.255.0.0
inet6 addr: fe80::20e:cff:fe34:11fa/64 Scope:Link

Base address:0xdcc0 Memory:fe6c0000-fe6e0000
When i try to ping the interface itself with the -I option, it only
works if i set the IP address, but not the interface name:
busybox.git$ sudo ./busybox -I eth1 192.168.105.1
PING 192.168.105.1 (192.168.105.1): 56 data bytes

busybox.git$ sudo ./busybox -I 192.168.105.1 192.168.105.1
PING 192.168.105.1 (192.168.105.1) from 192.168.105.1: 56 data bytes

--- 192.168.105.1 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0.052/0.061/0.069 ms
Is this the normal behavior? or have i hit a bug?
