Probably this related question has been asked many times. I looked at
the list archives but could not find a solution to this. Can someonw let
me know a solution to this problem ?

Iam trying to run lwip-0.5.3 under a machine running linux 2.4.2-2. I
also installed the tun-1.1 package. I was able to compile lwip for
unixsim.  I can see a tun device as /dev/net/tun. However, when I try to
run simhost I get the following output:

System initialized.
TCP/IP initialized.
Error /dev/net/tun
tapif_init: No such device

>From the tapif.c code under arch/unix/ I find that an open call to the
device /dev/net/tun is failing with an error No such device.=20

Thanks
Ganesh
