I can't connect to internet (via ethernet) from Manjaro NET Install ISO

Juan Lucas · 01-15-2017, 05:02 PM

Hi there

I got a new computer and want to install manjaro net edition on it, but I can't connect to internet from it.
I know the NIC and cables are working fine because I can connect to internet from a Debian installation on the same computer (On Debian I had to edit a little bit /etc/network/interfaces file to get it working)
My dhcpcd.conf file looks like this: https://hastebin.com/raw/warocaqeda

I tried running dhcpcd and dhclient -4 -v but they return

Code:

dev: loaded udev
DUID 00:01:00:01:20:0e:92:da:40:8d:5c:18:90:27
enp5s0: IAID 5c:18:90:27
enp5s0: soliciting an IPv6 router
enp5s0: soliciting a DHCP lease
enp5s0: using IPv4LL address 169.254.180.236
enp5s0: adding route to 169.254.0.0/16
forked to background, child pid 1730`

and

Code:

respectively, and, after that, ping 8.8.8.8 returns Destination Host Unreachable

This is my ifconfig output:
https://hastebin.com/raw/mofiyisiqe

ethtool enp5s0 output:
https://hastebin.com/raw/efimakadag

lpsci -v output:

dmesg | grep r8169 output:

ip link output:

Could you help me to get connected?

Thanks in advance

If you are trying to run both dhcpcd and dhclient they are likely conflicting.

Code:

dev: loaded udev
DUID 00:01:00:01:20:0e:92:da:40:8d:5c:18:90:27
enp5s0: IAID 5c:18:90:27
enp5s0: soliciting an IPv6 router
enp5s0: soliciting a DHCP lease
enp5s0: using IPv4LL address 169.254.180.236
enp5s0: adding route to 169.254.0.0/16
forked to background, child pid 1730

is expected output for dhcpcd

Juan Lucas · 01-15-2017, 07:19 PM

But after running dhcpcd, I run ping 8.8.8.8 and get

Code:

From 169.254.180.236 icmp_seq=1 Destination Host Unreachable
From 169.254.180.236 icmp_seq=2 Destination Host Unreachable

D:

Shouldn't I get a message of 'leased <some address> for 86400 seconds' or something like that?

TheEzekielProject · 01-15-2017, 08:05 PM

In your first post you said the output of dhcpcd returned what I quoted in my initial response, which seems to indicate that it received a lease from your router. What is the output of

Code:

ip a

Juan Lucas · 01-15-2017, 08:56 PM

That Is the output of dhcpd, but, it never says that it received a lease :O , it just says that is using IPv4LL address 169.254.180.236 (which is useless :P).
'ip a' output is

Code:

show it was successful as well

Try

Code:

ping -c 2 www.google.com

Juan Lucas · 01-15-2017, 09:58 PM

IP addresses within the block 169.254.0.0/16 are link-local addresses. Link-local addresses are assigned to interfaces by host-internal, i.e. stateless, address autoconfiguration when other means of address assignment are not available.

As I said, the output of 'ping 8.8.8.8' is:

Code:

From 169.254.180.236 icmp_seq=1 Destination Host Unreachable
From 169.254.180.236 icmp_seq=2 Destination Host Unreachable

Sorry, I missed that that was a link local address. Try with the option

Code:

--noipv4ll

Meaning the dhcpcd command

Juan Lucas · 01-16-2017, 05:07 PM

Tried adding --noipv4ll parameter, but no luck; I still get the same output

TheEzekielProject · 01-16-2017, 05:35 PM

That's strange. Is it still assigning a link local address even with that option? You might try putting it in your dhcp.conf and see if that makes a difference. If it's still assigning it a link local address, it seems for some reason must not be reading dhcp.conf

Jjanel · 01-17-2017, 01:43 AM

Hmmm... need to 'dig out' the 'hidden clue' here (but I don't have definitive way, sorry)

Manjaro is usually 'pretty good' (I VBox'ed manjaro-net-16.06.1-i686.iso per early LQ recomendation)

To clarify, what is running (&your output posted from) is the .iso (not a 'modified' install), I assume.

What [exact] "edit a little bit" was needed to make Debian work? Any ISP details relevant?
(when my 'unfriendly' wifi ISP refuses to 'lease' me a 192.168.6.x, I get [random?] 169.254..)

Can you run [either] dhcpClient with more/max verbose debugging? Extreme: tcpdump?
