#198307 — Network configuration

[Multipart message — attachments visible in raw view] — view raw

If I choose to configure the network during installation, where can I
configure the network after?
on which file, because in /etc/network/interfaces I don't see the ip
address, subnetwork ...

It depends which pkg you choose to install during installation.
If you selected a desktop manager (gnome, mate ...) it is most likely 
that NetworkManager (NM), WICD or or similar apps is installed.

For some hints of what is configuring your interfaces you might look at 
the top of:

/etc/resolv.conf

Not in my experience.

At one time, if you did a non-expert install with no network DHCP
server, then you got no networking, even after a netinstall. It bit me
around the time of etch or lenny. I've no idea if it's still true today.

I think there's only one Brian over there in the UK somewhere, and here's what
he said a year back that pertains (if the bug still kicks) to whatever it
is we're talking about here (in the interests of precision and clarity):

 netcfg sets up the network during installation and writes a temporary
 /e/n/i stanza. If a user installs a DE and n-m is installed the stanza
 is not copied to /target, the assumption being, I suppose, that the user
 would want n-m to handle the network. This happens when either a wired
 or wireless connection is used to install.

 If the user uses a cabled connection but does not select a DE the stanza
 is copied to /target.

 If a user has a wireless connection but does not select a DE the stanza
 is not copied to /target but rewritten to contain loopback only and then
 copied over. On first boot there is no external connectivity. Your guess
 is as good as mine why a wireless installation is treated differently
 from a cabled one. I have never seen any adequate justification for
 denying external connectivity in this circumstance.

So it is the experience of wireless people, I guess.

Thank you for all your reply,

I configured the network via the GUI during installation, the network works
perfectly.
I just want to know if I want to change the address or ..., without going
through the GUI, where I can make my changes, knowing that the

/etc/network/interfaces file does not contain my configuration :

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).


source /etc/network/interfaces.d/*


# The loopback network interface

auto lo

iface lo inet loopback

To answer that question we/you need to know what app is configuring your 
interfaces.
Then you can reed how to configure that app through CLI/config file.

I don't have access to images.
What is the output of:

$ cat /etc/resolv.conf

Ok -- The app "NetworkManager" is managing your interfaces.

To deal with NetworkManager through the CLI and config files you will 
need to do some reading:

https://developer.gnome.org/NetworkManager/stable/nm-settings-keyfile.html
https://developer.gnome.org/NetworkManager/stable/NetworkManager.conf.html

If you do a command line install with no graphics, you end up with no
network configuration once installation completes.I left some writing on
wiki.debian.org for how to configure wifi to work for command line
installs on post-install boot and that uses ifup and ifdown.  I don't
know what happened to the text on that site since I put it up in pure
ascii without any markup editing.  If need be, I think I can find it
among my files here.
