Your name? Govi or Govinda? Anyway underlying your seemingly facile question are certain deep technical topics. If you configure 3 different IP addresses with different netmasks then they belong to different subnets/networks. But if you assign the same netmask then of course the network is same. But in all cases the packets always come out and come in thro' the same physical eth0 interface. You can however change the source IP of packets with the appropriate switches if a particular command supports that. I am sure ping does. I normally do not have any issue with which interface is chosen for packet transfer. And I do a lot of my dev work using IP aliasing. I use qemu and with that I can get a lot of virtual interfaces for doing the sort of interface specific manipulation and monitoring that you want to do. -Girish -- Gayatri Hitech http://gayatri-hitech.com [email protected] _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
