#172904 — Unidentified subject!

SubjectUnidentified subject!
Message-ID<smvPP-4nU-19@gated-at.bofh.it>
Clean install of deb8 (jessie)on my Thinkpad T4220i laptop. went well
except for the fact that the network configuration
with DCP failed.

I was given 3 options.
1) try it again. This was hope over experience.
2) configure manually. Great if I had the first inkling how. I'm a
complete neophyte when it
   comes to networking.
3) continue without configuring a network. The only one that would let
me continue the
   installation.

I have a functioning desktop pc so I compred some files w/ the laptop.

/etc/networks was identical as was /etc/network/interfaces (from what I
could see) and /etc/NetworkManager.

I looked at "man interfaces" but quickly got in over my head.

Multiple installs resulted in the same failure.

Right now I feel like I'm drowning and could sure use a pointer or six.

If any more information is required (and I'm sure it is) let me know.

Normally, you would have a DHCP server, perhaps included in your
router, which would hand out local IP addresses.

Possible cause 1: you don't. 

Possible cause 2: you do, but it is full or configured not to
give this machine an IP.

Most likely cause: underlying networking is not working right.

Ethernet or wifi?

What does "ip l" tell you? "ip a", too.

If it is wifi, I think you need the firmware-iwlwifi package from non-free  
for this laptop

Hi, Bob.

Welcome.

First, a meta-suggestions

  Try to use a good subject line (I tried to modify it).
  This list is read by many volunteers, and is pretty high
  volume. Nobody reads everything. A good subject line
  will make it more probable that your mail is picked up
  by someone knowledgeable in the subject matter.

Comments interleaved in your main text

This is probably DHCP. That means that the laptop tries to ask in
the local network for an IP address and gets assigned one by the
(local) DHCP server, which these days typically is the internet
router.

Question: is your Thinkpad connected to the local net via a
network cable? Or via WLAN?

Open a console. What is the output of the command

  /sbin/ifconfig

Could you paste it here?

> I was given 3 options.
> 1) try it again. This was hope over experience.

That means it isn't getting an answer to its DHCP requests. Most
probably it doesn't reach the network, but we can't know for sure
yet.

Perhaps the output of /sbin/ifconfig on the desktop PC would be
interesting here as well.

It could be as simple as the laptop requires non-free drivers (e.g.
Intel), which were not installed as part of the Debian setup process.
I had that issues with Wheezy and an Intel 7260 WLAN card.

I just plugged the laptop into the LAN, and grabbed them that way.

No worries. Mail is asyncronous. In my eyes, its biggest asset.

This means that eth0 hasn't an IP address assigned. This is consistent
with DHCP failing. Your laptop sends a DHCP out and expects some answer
(from the "modem" or from the network infrastructure behind it). No
answer came, probably.

This is the "local" interface. It's always there. It doesn't correspond
to any hardware. For our quest, you can safely ignore that.

> > > I was given 3 options.

[...]

There is no way forward until we sort out how to assign an IP address
to your interface (be it via DHCP or manually).

Can you describe this "modem" a bit more? It may well be that it isn't
talking regular IP but needs PPPoE[1] (PPP over Ethernet) or some such.

Nothing to do with the OP's issue but people might be interested in
knowing that this stanza is not a requirement for inclusion in the
interfaces file. If it is left out you still get a loopback interface.

it will go to never there.
