Trouble configuring network   
Hello,

I'm having trouble configuring network through DHCP in my target which uses 6.4.0.
I execute the following in the target:

io-pkt-v4-hc -ptcpip &	
waitfor /dev/socket
inetd &
dhcp.client -i en0 -m -u -T 10

After this when I check up with ifconfig I find that the system is not configured to any IP. Is there something I'm 
missing here or is there any other dependency which I should have?

Thanks,
Lakshminarayanan.R

RE: Trouble configuring network   
Hi:

  If there's no typo, then you haven't specified any hardware driver for io-pkt to load (the "-d" option).

Re: RE: Trouble configuring network   
You are right. en0 wasn't mounted. I managed to configure it in DHCP. 
But, now I'm trying manual configuration. Just replacing dhcp.client with ifconfig
ifconfig en0 192.168.12.11/24

This configures the network. But when I try to ping it from outside, the request times out.

What could be the possible reason? Anything else to be done for this?

RE: RE: Trouble configuring network   
DHCP also configures such things as default routes and name servers.  If
you're trying to connect to your target from a host on a different
subnet, setting a default route is the first thing you're going to have
to do.

I'd recommend reading up on the documentation for networking (or simply
go to the web) for basic information on how networking is configured.

Re: RE: RE: Trouble configuring network   
Now, I'm able to hop the packets through the gateway. Route gateway wasn't configured and I did it with this command:

route add default .......

Still I'm facing an issue. If I give a route show (or) a telnet to another sys (or) a ping to another sys it is taking 
time, although it works.

But this is not observed with DHCP! Any suggestions on this?

RE: RE: RE: Trouble configuring network   
This is probably a name server problem.  Your apps are attempting to
convert an IP address into a name and this is failing.

You can test this with the ping application by adding the -n option
(don't look up names).

Re: RE: RE: RE: Trouble configuring network   
Yes, it is trying to look up the name links and with ping -n the delay is aborted. But, how to avoid this without -n?

You're on to the next thing.  Check the documentation (or the web) on
how you set up the name resolver (DNS).

In particular the documentation on /etc/resolv.conf, /etc/hosts
and /etc/nsswitch.conf in the utilities reference.

There doesn't seems to be any network driver loaded.
