Very Computer

Does somebody know how to setup a linux laptop without
network card to use all network programs (like apache
or ping) on the local station without having "network
unreachable" messages ?

Thank you for your help,
Manu

Yes, the standard setup of Linux should work, as you (should) have a
localhost.localdomain address of 127.0.0.1 in your /etc/hosts file.  You
should also enable networking in /etc/sysconfig/network - set
networking=true.  As long as Linux has the network destination "localhost"
available, networking works.

Bill Strosberg

  use  localhost (127.0.0.1)  (loopback interface).
  You can also simulate networking with the "dummy" interface.
  (replace dummyb y dummu0 if loaded in module)

  BTW,  give a look at "man ifconfig" and  "man route" ans so on.
  (NET-3-HOWTO)

Maybe a stupid question, but why would you wanna do that?

Plenty of reasons!  If you were on a deserted tropical island with a case
of rum, a beautiful woman, and orders to get a CGI application completed
within the next week, it would be wonderful to be able to develop and
test it without having to find a real network to hook into.  8^)

The original questioner does not give quite enough information to give
an answer.  What are you pinging when you get "network unreachable"?
The only thing you should be pinging is "127.0.0.1", and you should
not get "network unreachable" when you do that.  If the machine is
disconnected, then why are you trying to ping another host?

Everything should work fine once you understand what is happening on
your machine.  You should be able to use ping and apache just fine.
Post more details on exactly what you are trying to do and what happens
when you do it.

Of course, I didn't try to ping another host. My box is
named "chryseis" and when I try "ping chryseis" I get
the message "network unreachable". But as said by somebody
else, I should verify I set the dummy option when I recompiled
the kernel. But you're right: "ping 127.0.0.1" is ok.

It's the first time I set Linux for a standalone computer
(w/o network adapter), so I think I forget to check the
dummy option...

Well, I've checked and everything with the localhost is fine. Httpd is not
running anywhere else in init.d, yet Apache still just starts and stops
immediately. It's got to be something simple....
