hi i am running linux on my machine which is not connected to any network. it doesn't have any interface card on it. but i want to do some network programming on it. i want atleast three different networks configured. is this possible by configuring virtual interfaces? if i send a packet from one network to another will it travel through the whole protocol(TCP/IP) stack or just go through loopback interface(lo)? this is required, because i will be working on protocol independent multicasting(PIM). i want my computer to work as a router which is connected to three different networks through three interfaces(virtual if possible). i have the pim routing daemon which will do the job of routing. i only need three interfaces(eth0, eth1, eth2) without connecting my computer to any network and without any interface card inserted in it. i hope u got my problem. pliz help me ASAP. arindam mailto:[EMAIL PROTECTED] __________________________________________________ Do You Yahoo!?
