Exclamation how to test network programs with out LAN connectivity on FC5


Hi all,
I have been running FC5 for about 3 months and graduated from school. The problem is now that I dont have LAN connectivity is there a way to run the network programs that involve multiple IP addresses.Like binding a server to one IP and clinet to one IP. do I need to buy any hard ware? Please help.
Thanks in advance,
udai.

using the tun/tap devices you can do this. those devices simulate a network device, but pipe the data to a socket etc. see the documentation in the kernel sources (/usr/src/linux/Documentation/networking/tuntap.txt)

HTH,

Thanks for reply

Hi, Thanks for reply, it worked.
I already have a ethernet interface on my pc. can I create multiple ip addresses on my pc and simulate a network. can I create two taps for two different IP addresses.

Thanks,
Udai.
