[SOLVED]I can ping but can't do anything else

nasser · 2017-11-03 11:02:21

I have 2 Arch machines, and one of them worked for a year without a problem
But suddenly the internet connection has stopped on both of them and on a Win machine too, I can ping to any IP on the three machines but can't do anything else

Information about my main Laptop:
I use wpa_supplicant to connect

less /etc/resolve.conf

 nameserver 192.168.1.1

*Everything works fine on tablets and mobile phones
*When I try to connect through USB tathering nothing changes

*I posted this from my tablet

Can you ping machines not in your local network? What is an example of "anything else"? What fails, and with what error messages?

Note too that wpa_supplicant is not sufficient for a connection. Are you also running dhcpcd or something similar?

Sorry I meant I can ping to static IP's for WebSites but can't brows the website
"Server not found", and can't use pacman

And I run dhcpcd for the interfaces like "wlp2s0"

So if every machine has stopped -- Arch or Windows -- I would look to the router you are behind. Has anything changed there? Any other devices you can try?

Does your nameserver work (nslookup, ping with a domain instead of an ip)?

# test with your default nameserver
nslookup example.com

# test with google nameserver
nslookup example.com 8.8.8.8

# http test with curl
curl example.com

# http test directly to ip
curl --header "Host: example.com" 93.184.216.34

The router is fine (I can use my tablet and mobile phone and can ping to IP addresses)

nslookup didn't work with default nameserver

;; connection timed out; no servers could be reached

But worked with Google nameserver

curl:

curl: (6) Couldn't resolve host: www.google.com

But worked with http test direct to IP

Could you post

ip route

?

well, installing nmap sounds like a solution to the latter??

How?

seth · 2017-11-05 08:22:59

You mean how installing nmap is a solution to this problem?

And nmap:
Command not found

How did you install Archlinux?

I meant: given that the problem is complete lack of a network connection, it may not be easy or obvious to the OP how to install anything. I assume you were thinking that the OP could download the package elsewhere to removable media and then install the package using pacman -U or so?

Ok, tbh that question didn't cross my mind at all... (and the OP didn't ask)

The USB walk is certainly a solution that always works, but in the particular situation, changing the DNS server to 8.8.8.8 would very likely have provided a workaround (inferable from the context ant comment #13 suggests that the router rebooted or fetched a new DNS from the ISP to be wired through; android will for more or less sure at least resort to googles DNS)
