[gentoo-user] Internet

[Cahn Roger]

Hi,

Yesterday I tried to make a connection between my three PC
to manage my Epson printer: two with Win XP and Gentoo
and one with Win7.
I didn't succeed, but that's not important!
After reboot of the three machines
I went back to Win7: no problem
 and to my laptop with Xp and Gentoo: OK.

But the problem is on my desktop with two HD,
one with XP and the other with Gentoo amd64.
None of them can connect to internet neither gentoo nor XP.
I tryed many things (revdep-rebuild, verification in the box, etc.)
but I was unsuccessful. Here is what I become at boot:

Hi Roger,

It looks like your DHCP server isn't serving addresses.

If it's your Internet router you might try resetting it (power cycling
it.)  I've seen them get wedged specifically relating to DHCP with many
different consumer brands.

Todd

Well, it serves adresses for W7, and on the laptop for XP and Gentoo.
The box is configured with fixed adresses.

I'll try it!

Thank you again Todd

Your DHCP server serves addresses for other hardware OK?

Just not on this box running either Gentoo or W7?

When you say fixed addresses you mean the DHCP server gives out a
fixed IP address based on the MAC address of the requestor?

Can you check the DHCP logs on the DHCP server?

If that doesn't work, maybe a wireshark or tcpdump on your Gentoo
box and force it to send another DHCP request.

If you're using fixed IP addresses you might try manually configuring
the Gentoo box with it's IP address and see if networking all works
fine then?

Todd

> Your DHCP server serves addresses for other hardware OK?

Yes. A PC with W7, my laptop with XP and Gentoo
Both work fine.

The problem is on my desktop with two HD: XP and Gentoo
Both OS can't connect to Internet.

Yes. I put manually in the box (router) ip and mac adresses.

> Can you check the DHCP logs on the DHCP server?
No!

What does the router log show?

Can you please share:

ifconfig eth0

/etc/conf.d/net

In the box I stopped the option fixed adresses,
but the problem remains the same   :-(

It depends on your router.  Usually routers have at least a GUI control panel 
access and one of the pages shows recent attempts to connect and authenticate.

Are your running some sort of an access control list on the router and have 
not included your MAC address?

The Rx bytes is zero - your router does not seem to respond.

Does this also stay zero if you set up a static address and route on the PC 
and try to ping the router?

Try setting an address manually:

 ifconfig eth0 192.168.1.20 broadcast 192.168.1.255 netmask 255.255.255.0

 route add default gw 192.168.1.1 (assuming that this is your router) 

and then try to ping it:

 ping -c 3 192.168.1.1

If you can ping it and get a response then the problem is probably with the 
router.

My router hasn't this!

The MAC adresses are included in the box.

I put this in /etc/conf.d/net;  is it right?

> and then try to ping it:

The answer:

ping -c 3 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

From 192.168.1.20 icmp_seq=2 Destination Host Unreachable

No. Run them from terminal as root.
Then check.

Try changing ethernet cable and switch port for the pc that has the
problem, and ping the router again.

Then if the problem persists, delete
/etc/udev/rules.d/70-persistent-net.rules and swap the network card (if
it's not onboard) with another (PCI) that you know is good.

If the card is onboard, do not delete
/etc/udev/rules.d/70-persistent-net.rules, just add a PCI NIC, connect
the ethernet cable to this new PCI NIC and try to ping the router.

OK, the link is coming up.

I've forgotten where we left this ... Oh yes, your router was not responding.  
Once you boot up, have you tried:

/etc/init.d/net.eth0 stop
/etc/init.d/net.eth0 zap
ifconfig eth0 192.168.1.20 up
arping -c 3 -I eth0 192.168.1.1

If this does not return anything then try to arping other machines in your 
LAN.  If you are getting reponses from other PCs but not your router, then the 
ethernet cable is good, but the router configuration is not.

It is probable then that your static IP address/MAC number that you have set 
up at the router has some error with it.  Look at that again and check for 
typos.

You need to remove those lines that I asked you to type on the command line 
from the /etc/conf.d/net file - or look at the example file provided and use 
that to define static address/broadcast/netmask correctly.

Typically something like:

  config_eth0="192.168.1.20/24" 

should do it.  If you want to define a static route and dns server add:

  routes_eth0="default via 192.168.1.1"
  dns_servers_eth0="192.168.1.1"

HTH.

Well his /etc/conf.d/net file is now toast after what Thanasis had him
do.  So they're out of there now.  :-)

He should have already removed them (see the messages in the thread).
/etc/conf.d/net should be empty by now, which means it defaults to dhcp.

Sure, but if he had then he wouldn't be getting all these configuration errors 
when he tried to stop the service.

He shouldn't get those anymore with an empty file either.

If one wants to rebuild the /etc/conf.d/net file, he should take a look
at the example file /usr/share/doc/openrc-*/net.example as a guide.

Hmm ... something is not right at the router, or your ethernet cable is 
faulty/unplugged.

Are you sure that 192.168.1.1 is the correct address for it?  After you set on 
the command line your ip address using ifconfig run this:

arping -c 3 -I eth0 192.168.1.1

If your router is not responding, please check its firewall list and any 
access control lists you may have set up for it - you may have typed 
incorrectly the MAC address for your eth0 NIC.

Hi Roger,

The log you showed indicates that the PC is unable to reach the DHCP server.
As the issue occurs with both Operating Systems on the same machine makes me 
think there is an issue with the network-connection.

Can you check the network cable and connections to ensure that is actually 
correct?

No gateway defined.  :(

When you then run:

 route add default gw 192.168.1.1

to define a route manually what do you get in response and then what does it 
show:

 route -n

and what does ip show:

 ip link show dev eth0

I'm sorry. :) I didn't read the entire thread.

If you have another device with Internet connection you can download
the missing files and place it into your /usr/portage/distfiles

For example you can download from http://mirrors.kernel.org/gentoo/distfiles/

After the required distfiles exist, emerge should work.

OK, this looks good!

Can you please try to ping your router:

ping -c 3 192.168.1.1

if this fails try to ping other PCs in your LAN.  If that fails too can you 
use arping instead:

arping -c 3 -I eth0 192.168.1.1

or the same with the IP addresses of other machines in your LAN.

Can you ping your machine from any other PC on your LAN?  If not please change 
the ethernet cable.  This seems soooo much like a hardware failure I can't 
think of anything else.

OK, let's look at this from the router side ... what router make & model do

I'd go even more basic, connect directly to another computer using a
crossover cable, set addresses on both with ifconfig and see if they can
ping one another. This really sounds like broken hardware and if the
cable is fine, the NIC is suspect.

Or swap the cable with a working PC and vice-versa.
If then the issue stays with the currently broken one, then the issue is 
probably with the network card in the broken one.

If the issue affects the other PC, then the problem is the cable. I've had 
issues before where I couldn't get a connection using CAT-6 cables. Didn't 
check properly and the network card wouldn't allow it. The card did, however, 
claim there was a link...

I'm afraid you're right!
But, as I just wrote, the NIC is included in the motherboard...

PERHAPS a solution: try a restore from the
external HD where I have saved a week ago with
fsarchiver on SystemRescueCD.

No amount of farting around with software will bring dead hardware back
to life. Just try another NIC, at least that way you'll know.

OK, I don't know how much SFR have locked down their firmware.  You should be 
able to access its control panel using a browser (using another PC of course) 
and pointing it to http://192.168.178.1 (the default address for this router 
seems to be http://192.168.1.1).

Then work your way through the menu until you find a log.  If there is one 
available then have a look at what it shows when you try to connect with your 
faulty PC.

After the SystemRescueCD was launched, ifconfig

What do you mean bad address?
Did you start the network? It should get an IP address from the router's
dhcp server.

Once you are inside the SystemRescueCD (has finished booting) try to
start the network. It should get an IP from the router's dhcp server.
If it doesn't, then try to assign manually one to eth0, and test.

OK. I make an ifconfig and the adress is: 169.264.240.204
and of course Firefox has no connection

After reading this thread, I'd say that either the NIC is faulty or he's 
using a cross-over cable instead of straight-through.

Re: [gentoo-user] Internet

Yes, a bad spirit!!!

I resume.
1-The problem occured after I tried to share my Epson printer
between my three PCs: Gentoo+XP (twice) and W7
2-The NIC is included in the motherboard (Asus P5K-E)
3-The cable from the dektop, where the problem exists,
works fine on the laptop which is without problem,
and the cable from the laptop doesn't work on the desktop.
Therefore, I think, that's not a cable problem.

Can you get hold of a PCI* NIC to try, it will appear as eth1. If it
works the problem is with the motherboard NIC. I'd also check the BIOS to
make sure the pixies haven't disabled the NIC in the BIOS settings,
stranger things have happened, sometimes disabling and re-enabling a
device can resurrect it.

What Cahn Roger means is, can you get hold of a network card that is not 
included on your mainboard?
In other words, can you test using a new network card that you built into the 
computer?

Can you try checking the BIOS settings to see if there is something there that 
might cause problems with the network device on the mainboard?


Based on all the information provided already, there is a very good chance 
that the network card on your mainboard is no longer working correctly.
I am, to be honest, hoping that it is caused by interference of the printer or 
by a BIOS setting.

I'm afraid you're right, because neither Gentoo nor XP work and they're
on two different HD.

It was my first idea, because it arrived just afterwards.

I verified, but didn't see any wrong setting

I'll try with an other network card...when I get time!

Re: [gentoo-user] Internet

[William Kenworthy]

Apologies if I missed someone already asking these:

1. are the lights on or flashing with a cable plugged in and pinging
something valid?

2. can you ping yourself (both 127.0.0.1 and the nic IP) - cable plugged
in

3. do you have IP tables installed - "iptables -vnL" and check you have
not firewalled yourself off from the world somehow.

4. set up a ping and check "dmesg" and terminal 12 (<ctrl-alt-F12>) for
anything meaningful.

5. as an outside chance, run "modinfo [eth_module]" - get the right
module name from "lsmod"

That indicates a problem - if a packet is going out/in, the lights

normal, seeing the cable and a valid line discipline the other end

ntpd is the network time protocol daemon - its basicly complaining about
no network.

in this comntext [ ] normally means optional or "replace this" so you
need to do an lsmod, identify the module for your ethernet card (sky2?)
and rum "modinfo eth_module" replacing eth_module with the real module
name.

Next I would remove the switch and use a crossover cable to another
machine and use ethtool on each end to go deeper into what the
hardware/cable is doing.  You can still get problems with one end being
say 10Mb/s and the other running a different speed/duplex etc.  I am
finding that 1Ghz chips seem less than reliable in this regard to older
switches that way!  I also have some 4 port sun 100mhz cards that need
the other end always up before powering the machine they are in on as
nothing I can do once up will get the ends in sync.


also try "cat /proc/net/dev" and see if that shows anything useful

Excuse me; I looked only half a second!!!  Yes they are flashing.

Since this night I found something important: the little box
put in the socket wall from where the cable goes out, doesn't
no more work!!!
When I put it on my two other PCs they can't connect to internet.
For this reason I use one of the boxes, which works, on my desktop.
Between this one and my laptop pings are ok.
The two PCs can recognize each other.
But, on my desktop I don't have yet internet connection.
Is the network card even so out???

Re: [gentoo-user] Internet

> But, on my desktop I don't have yet internet connection.

I don't know why, but my desktop is now connected to internet!
The only thing I did was a reboot!

Thanks a lot to you all who tried to help me.
It was a hard way to obtain the solution.
The problem was really a hardware one,
not the cable, but just the little box connected
to the wall socket for my connection to the router
through the house electric circuit.
But the most important thing is to succeed   :-)
Once more a great thank you.
Roger

You've been using powerline networking and never thought to mention it
throughout this entire thread, even when people were saying it had to be
a hardware problem?

Well, as long as your connection problem is now solved you can carry on with 
using your Gentoo!  :)

Yes, I'm very happy to be able

Long life to Gentoo, indeed!!!

Wow...

All of this wasted bandwidth and you are just *now* getting around to
mentioning that you are using a powerline adapter?

Remind me to never waste time reading one of your threads again.

Is the printer still connected and switched on?
It's possible this is part of the problem

Those can, unfortunately, also break

I agree, the cable has been proven to work.

Or simply, shut down everything that's networked, eg. router(s), 
switch(es)/hub(s), computer(s),....

Wait 5 minutes and then restart the whole thing.

I did it, but without success  :-(
