I need to use several IPs on interface in Linux, and switch it, but it's not working.<br>
for example:
# ifconfig
eth0 Link encap:Ethernet HWaddr 90:2b:34:33:80:65
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0

# ip route

192.168.1.0/24 dev eth0 scope link src 192.168.1.99
# ping 192.168.1.50

and then i use Curl
# curl 192.168.1.50
and tcpdump:

and source ip is still 192.168.1.1, what am i doing wrong?
UPD: BTW, just tryed same thing on Ubuntu 10.04 with 2.6.32 kernel, everything works good, and you even dont need to add "-I" to "ping" command, it seams in my kernel (3.2.0) somebody broken this feature.
