[uml-user] networking and DHCP questions

[Tasos K. <ak...@in...>]

Hi,


I play with UML for some time and I managed to set everything up and 
running OK, including networking. Nevertheless, there is still a nagging 
issue: I cannot setup the eth0 in the uml machine, in the case I have 
boot the uml as a *plain user*. More specifically, when I run 'ifconfig 
eth0 10.0.0.2 up' I get a:

TUNSETIFF failed, errno = 1SIOCSIFFLAGS: Operation not permitted

Otherwise, when I boot the uml machine as root, everything goes fine. I 
checked that indeed the /dev/net/tun has r/w permissions for all, and 
here is where my mind stopped creating new ideas... I would be grateful 
for any help.

Another problem is that I haven't yet managed to boot a uml using DHCP, 
TFTP, etc. I can do this for any other linux system (e.g. built an 
appropriate kernel, etc.), but in the case of a uml I still cannot make 
it work. I bet it has to do with the boot options, but I haven't seen 
any *detailed* documentation about this. So the question is: Are there 
any pointers on this matter?

Thanx in advance
